Journal - Essay Example We also learnt about the audience of the story. The people who read stories and listen to stories are the audience. We learnt that good compositions are about things that the audience knows. Week Three During this week, I learnt about analysis. Analysis is looking for facts and issues that are presented in the composition. Analyses are important because they help us to understand the issues that the composition is writing about. This lesson was important because it helped me to get good skills of analyzing compositions and other writing in English. Week Four This week was important because I was tested on the skills of how to analyze something that I had read. It was an important week in the classroom. In this week I was able to write a paper from the article called â€Å"The Responsibility of Intellectuals, Redux.† I was interested in this article because I read it and understood what it was about. It was the first assignment of analyzing an article that was written in Englis h language. I was an important test which helped me to sharpen my analytical skills. During this week, I gained skills of analysis and summary. I was able to read articles written in English and then summarize them in my own words. It was an important task that helped my process of learning, reading, and writing. Week Five This week was important because I was taught about ethos, logos, and pathos. ... Ethos are the symbols which writers use when they want to explain something in their writing. Pathos are the things that writers use to convince the readers. Pathos use emotions to make meaning out of the various issues that writers use in their writings and articles. Many times, the use of these ethos and logos are brought about through articles and stories. I also learnt about logos. Logos are used when writers want to use facts and logic in in their articles and other writings. These week helped me to understand the way different writers use different methods for making meaning from various sources. I can also use ethos, logos and pathos to write stories and make meaning from them. Week Six During this week, I was able to learn about poetry. We learnt about poems and the way of reading and writing poems. We were taught the way the language used in poetry is different from the language that is used in other forms of writing. Usually, the writing process is important because it help s people to understand the use of language very well. I was able to write some poems and to read others. I was also able to analyze some poems that are generally brought within the element of writing. Week Seven During this week I was able to try and write about the things that I was taught in class. It was a week that helped me to practice my new skills. Week Eight This week was important because it helped me to understand poetry and the styles used in writing of poems. I was able to read about tone by looking at the words that were used in writing of the poem. I have developed the skills of writing about the things used in poems in ways that are creative and which respond to the challenges of everyday life. Week Nine During this week I was now able to practice

The European Union and the common European currency, the Euro Essay Example for Free

The European Union and the common European currency, the Euro Essay The European Union (EU) is an economic and political partnership of 27 nations with a citizenship base of 495 million persons. The EU functions through three bodies. The European Parliament which represents the people, the Council of the EU which represents the governments of the member states, and the European Commission which represents the common interests of the people and the governments. This operating method is called supra nationalism and is characterized by shared power among individual governments. One way the the EU accomplishes its goals is through the use of a common currency, the Euro. According to the European Commission website, the Euro was introduced in 1999 and is currently used by 15 member nations including, by order of adoption, Belgium, Germany, Ireland, Spain, France, Italy, Luxembourg, the Netherlands, Austria, Portugal, Finland, Greece, Slovenia, Cyprus, and Malta. The purpose of the Euro is to create a common market. Of the nations that have not adopted the Euro, two have been exempt by treaty (Denmark and United Kingdom). The others are newer EU member nations who have not met the requirements to adopt the common currency. Participating nations must adapt their fiscal and economic policies to mirror those of the EU. The Euro reduces trade barriers among member nations. It also facilitates and enhances international trade opportunities for member nations by reducing currency exchange costs and protecting member nations from fluctuations in currency values in the international market. For example, the Euro helps member nations to protect their economies from extreme fluctuations in international oil prices. Several nations purchasing oil in the common currency gives them greater negotiating power based on the amount of Euros invested in the oil markets.The Euro fosters a sense of European identity similar to how the American identity is common across 50 states along with the symbol of the U. S. dollar. Works Cited European Commission. The Euro. Economic and Financial Affairs. 23 Oct. 2008. http://ec. europa. eu/economy_finance/t he_euro/index_en. htm? cs_mid=2946.

Why Is English Considered a Global Language?

Why Is English Considered a Global Language? Abstract This project aims to show us why the English known as a global language and why other languages do not have this ability. Also introduce some other languages such as Chinese that can be replaced with English and their capability of being a global one. Key words: english , global , language , capability. Introduction We all are able to communicate freely with one language to people all around the world. A single language would help to reduce misunderstanding and miscommunication. People will need to learn this one world language, whichever that may be, but we will also never forget older languages completely. It means that we can use both of them at same time for the several reasons. We use our mother tongue in our country (home town) and use second language (global language) for communicate with people that don’t know anything about our mother tongue or for some other reason like job, travel, migration and †¦. . Global language A language is called a â€Å"global language† when it achieves the official position and education preference in every nation, that language will finally come to be used by more people than any other language. The essential reason to make a language global or international is the power of its people. The power includes the power of military, politic and economic. Military power, political power and economic power are the three essential factors to make a language global and to keep its status (Culpepper, 1997). What does the global language do? When a new language is introduced to new communities, and a new better life is achieved by the new language, it makes people prefer to use the language than their own language. In turn, the low frequency of using particular language may cause the language to disappear. This was true when English was introduced to academic life (Kaplan, 2000). If the language is no longer the key in communication, it will not live anymore. People will forget it. Many factors cause to the death of the languages that cannot known as global language like War, revolution, economic development or urbanization (Kaplan, 2000). But the development of some areas, like aviation, tourism and banking can be help to be as a global. English English is universal language. It is the worlds second native language, the formal language in 70 countries, and English-speaking countries are accountable for about 40% of worlds total GNP. English can be used everywhere with educated people around the world. It can be used in media, cinema, pop music, TV and †¦for anyone who knows English (Bond, Michael, 1751). From Old and Middle English, English was spoken early in the last one thousand years. Examples of language written at that time, such as the works of Chaucer (mid to late 1300s) are useful in supervising linguistic evolution over the last thousand years. In these works, often spellings will be indistinguishable, but once pronounced phonetically, are understandable to modern English speakers (Sapir, Edward, 1871). Why English is the Most Widely Used Language in the World? 1-Some people may disagree that â€Å"English is the world’s most important language.† It is definitely the world’s most widely used language. It is spoken by a number of people 800,000,000 by a conservative appraise 1,500,000,000 by a liberal appraise. It has official status in over 60 countries. 150 million people use English fluently as a foreign language. English is also the language of international air traffic control, and the principal language of world publishing, science and technology (Crystal 2001). 2- In the postcolonial world, English is often used outside the domestic area, discussions of the links between English and Anglo culture may even seem repulsive. Speakers of English—in Britain, the United States, and elsewhere—discussions of possible links between English and Anglo culture may also seem to be best avoided (Quirk et al. 1985). 3- English is also important in business. 84% of companies want English as a foreign language; only 32% require French (Felberbauer 1996). In the Austrian job market, English is pay heed to as a basic qualification; therefore not knowing English may be a conclusive deficit. In Austrian businesses which operate internationally the internal use of English is not so much a feature as it is in Scandinavia (Dension 1981). According to research conducted by Stockinger, secretaries, for instance, are expected to be able to hold telephone conversations in English while technicians have to be able to read technical literature in English (Stockinger 1995). The Significance of Learning English: English may not be spoken language in the worlds, but it is an official language in a large number of countries. It also very important for whom works in global workforce because English is the language of business in world, so it had become necessary for people to speak English. Another reason for learning English is that many of the worlds top films, music and books are published and produced in English. Therefore by learning English, you will be able to have a great understanding. And also most of the content produced on the internet is in English. So knowing English will allow you access amount of information which may not be otherwise available. Chinese The Chinese language is the oldest language in the world with six thousand years of history. Chinese character inscribing has been found in turtle shells dating back to the Shang dynasty(Reid, Thomas, 1890). Chinese phonetics is very complex, making the learning of the language a far more difficult role than learning English (Simon-Vandenbergen, Anne-Marie, 1937). The written language is a common form of communication. Even though people are not able to orally communicate in different district, they are able to understand each other in writing (Saltman, Michael, 1903). Chinese is already the most widely spoken language in the world, but that is because of the large population of China (Aleksandr, 2001). Chinese is not suspended to pass English as a global language. The Chinese economy is strong enough to raise the cause and popularity of its language, just like the English did. But, it is possible that China economy is a result of its ability to conform to others’ languages and way of work rather than the task of the Chinese language on other countries (Spevack, Marvin 1985). In business, Chinese is the most useful language like English. Transacting business matters using a common language is essential for camaraderie building but also for the speed and effectiveness of your negotiations (Thompson, 1998). France French represents different cultures around the world. It is used on five continents, in more than fifty countries. French is one of the six official languages of the United Nations and the official language of the Olympic Games (Vera. 2004). It provides the base for more than 50% of the modern English vocabulary, which improves presentation on standardized tests. French is supported by over 35 years of research and has been proven to be successful with students of all races, economic status and levels of English expertise (Quinn, Naomi. 2002). The importance of French has economic importance for major economies in the world, For example, French is the official global language of Canada, which performs major trade deals with the US. The knowledge of French for traders to such countries becomes all the more important (Jeremy. 1999). Being the second most taught language after English and having a readership and with the number of its students, French is absolutely the language to know these days. With English, French is the only other international language; being spoken in 5 continents (Steven. 2002).France has not lost its level of development in language. France is still a highly respected country, and still one of the top romantic languages in western civilization. The United Nations communicates have only two languages: French, and English. There are parts of Africa where French is still the native language, along with several islands. Test: I did a test on two groups. Group 1, who decided to learn English as second language Group 2, who decided to learn French as second language. I asked same question from two groups. Here are the questions and answers: Question 1: why are you choosing this language to learn? Group 1 à ¯Ã†â€™Ã‚ ¨ we choose this language because it is an international language and is more important than other language to learn. Group 2 à ¯Ã†â€™Ã‚ ¨ because nowadays some other language such as French comes to high level in international position and it may know as global language instead of English. So we try to learn it to be modern and update with worlds language changing. Question 2: How much do you want learn this language? Do you want to learn just for being good at conversation or more than it? Group 1 à ¯Ã†â€™Ã‚ ¨ No, not just for conversation. We try to use it in our daily life such as reading English books, articles and watching English movies. Looking for medicine news in the internet and †¦ Group 2 à ¯Ã†â€™Ã‚ ¨ yes actually we learn it to make conversation, greeting and understand what people say. Result à ¯Ã†â€™Ã‚ ¨ nowadays we choose language instead of English just because of communicating, making conversation and understanding what other says. But we choose English to learn for several important reasons. As I mentioned before, we use English to being able to surf the internet, read the international book and magazine, being aware of news around the world and †¦ Conclusion We result that it is no surprise that English is becoming the language for international communication. English is the most widely spoken language of the world because of the power the United States in economic and politic. English is the mother tongue of 380 million people, and it is used worldwide by the newspapers, magazines, scientists, businessmen, and politicians. One billion to 1.5 billion people around the world presently speak English. It is the most widely language in 70 countries (J. Draper. 1994).Globalization at the end of the twentieth century is occurring through the media, and technology, thus affecting languages worldwide (Sebesta , 1996). In my idea, languages have fallen and risen with the military and economic growth of a nation. Western culture has a large influence to keep it raise and use these power to impose the word for being as a global language. References STIG HJARVARD (2008).

Argumentative Essay: The Dangerous Expansion of Federal Power :: overextension of federal power

In 1995, there was great consternation when the Supreme Court ruled that carrying a gun near a school was not interstate commerce. On May 15, 2000, there was great consternation when the Supreme Court ruled that rape was not interstate commerce. It is a sign of how twisted the law has become that each of these common sense rulings was by a narrow 5 to 4 majority. While the 1995 case involved a federal law against carrying a gun within a certain distance of a school, this year's case involved a woman suing two men for rape under a federal law. Neither case was about whether the law was good or bad. The cases were about Constitutional limits on the powers of the federal government -- and all our freedoms depend upon maintaining those limits. The feds have been getting around the Constitutional limits by claiming to be regulating interstate commerce. But the Supreme Court didn't buy it. Rape is already illegal in every state. What the recent ruling said in effect was: You are in the wrong courthouse, lady. Sue those so-and-so's in the state courthouse down the street. State courts have the power to do everything up to and including executing people, so sending a case to a state court is no wrist slap. Why does it matter whether a case is tried in a federal court or a state or local court? It matters because a concentration of power is dangerous. The people who wrote the Constitution of the United States understood that -- and feared that -- even if too many of us today do not. The familiar division of federal power among the President, the Congress and the Supreme Court was just the beginning. The Constitution also made it possible to impeach anybody who abused his power. In addition, the crucial 10th Amendment to the Constitution said that the federal government had the power to do only what it was specifically authorized to do, while the people or the states could do whatever they were not specifically forbidden to do. This was understood for about 150 years. Then, during the heady days of the New Deal, the federal government's power to regulate interstate commerce was stretched to include virtually anything that the politicians in Washington chose to regulate. In one case, the federal government's agricultural laws were applied to a man who grew his own food in his own backyard.

The Impact Of Hydroelectric Power Development Environmental Sciences Essay

Over the old ages, there has been increasing involvement in electricity coevals utilizing hydropower. However, it is merely late that the impacts of hydroelectric power workss on the environment have been recognized ; until now, it was assumed that hydroelectric power coevals was a clean and environmentally friendly electricity production method, compared to other methods. After extended research, it has been found that hydroelectric power production has some impacts that include production of nursery gases from the disintegrating flora that have been submerged in the dike, and implosion therapy of large land countries, rendering them unfit for agribusiness and other human activities, among others. Possibly the biggest impact from hydroelectric power production is the consequence it has on H2O quality. Dam building, for the intents of power production, can alter the measure and quality of H2O of a river. The disintegrating flora contains bacteria that may besides transform the quicks ilver found in basic reservoir stones into a H2O soluble signifier, which builds up in the fish organic structures and accordingly presenting a wellness hazard. This paper will research the impact of upgrading of bing hydroelectric power workss on H2O quality by, foremost, depicting typical proposed enterprises and options when upgrading bing hydropower workss, and so researching the environmental impacts of such proposed enterprises and options. 2.0 Description of proposed enterprise and options For any undertaking that aims at upgrading an bing hydropower works, the chief aim should be to increase efficiency and increase energy production and end product to the upper limit with no unwanted environmental impacts.2.1 Upgrading bing hydropower workssSeveral methods exist that can be used to increase the production of power at bing hydropower workss. Normally, these methods can be grouped into two: methods that increase the power production efficiency and methods that increase the useable H2O or caput volume. To better efficiency, old turbine smugglers and Gatess can be replaced with newer, more efficient designs ; coatings can be used to minimise loss of energy through clash in flow channels ; the public presentation of the turbine can be tweaked ; turbine smugglers can be replaced with newer 1s holding a similar design to cut down pits and other defects ; generator efficiency can be increased by rewinding them ; H2O escape can be reduced in Gatess and other constructions ; junk path cleansing can be bettered to minimise clash losingss ; and automated systems for aggregation and analysis of diagnostic informations can be set up. To increase the useable H2O or caput volume, the dam lift can be increased to increase the caput and storage capacity ; more turbines can be added to utilize the H2O that is being spilled ; put ining newer turbines and generators that have wider flow scopes ; and other alterations can be effected during distribution of storage and releases of the reservoir.2.2 Retrofiting dikes to develop new hydropowerThe chief activities during retrofitting a dike for hydropower coevals include: constructing sluicegates, consumptions, and a human dynamo that may, in high-head dikes, be located downstream, or, in dikes with low caput, replace subdivisions of the bing construction ; employment of extenuation actions to minimise the undertaking ‘s impacts ; hard-on of power lines to link the undertaking into the bing power grid ; and rerouting through the H2O turbines. Monitoring of quality of H2O, testing to forestall fish from come ining the turbine, edifice of fishing installations, and flow release conditions can do up the extenuation actions.2.3 Options to hydropower development at bing dikesWhen upgrading a hydropower works to better its bring forthing capacity, it is presumed it replaces the bing capacity since it is dearly-won to run because of high costs, for illustration disused workss or those that use dearly-won fuel, and the new capacity that is more expensive than hydropower coevals at bing dikes. To find the right capacity mix that the proposed hydropower ascent will replace, there is demand for a complete respect for future energy disbursals, the nature and location of bing and future hydropower workss, and environmental factors particular to a site.3.0 Environmental impacts of the proposed enterprise and optionsAs has been established, any hydropower development, and other methods of bring forthing power, causes several environmental impacts. The following subdivisions explore the impacts of hydropower ascents and besides for power coevals utilizing fossil fuels, which is the most likely option.3.1 impacts of upgrading bing hydropower workssNormally depending on the type of upgrade being done, the environmental impacts of hydroelectric works ascents are non as terrible when measured up against other energy development impacts. In fact, upgrades that merely necessitate the generators or turbines to be replaced, go forthing the reservoir ‘s volume and release timings unchanged, have few immediate impacts and may even hold several enduring environmental benefits. The ascents that see the volume and release timings change on the other manus may some permanent impacts.3.1.1 Water resources3.1.1.1 Construction ImpactsMinor ascents do non necessitate much work and therefore hold small or no impacts on the H2O resources, like eroding, oil spills, and riverbed break, among others. However, major ascents would necessitate more wide building and therefore the impact on H2O resources is increased. Activities in such ascents such as digging or heavy machinery usage during building addition the local creek beds ‘ and Bankss ‘ eroding, doing more sediment tonss and possible deposition downstream. The redistribution of deposits by building may hold harmful effects when the taint of the deposit is local. While enduring impacts on the H2O quality are improbable, building during ascents may take to short-run impacts like little oil spills. Due to the arrest of H2O flow in major ascents, short-run dewatering and stagnancy of the tailwater may happen, ensuing in high growing of algae and changing concentrations of dissolved O ( DO ) which finally adversely impacts aquatic life.3.1.1.2 Decreased AerationTurbines able to utilize higher flows may be installed during undertaking ascents where spillage of flow occurs via wasteweirs or Gatess because the bing turbines ‘ size can non utilize all the flow. During spillage, the spilled flow may slightly hold increased DO concentrations, or become aerated. When the tu rbines ‘ capacity is increased, there will be an addition in the flow per centum in the turbine, where aeration is minimum or absent. Entire concentrations of DO would diminish in undertakings where the DO concentration is low and an ascent would do less flow aeration during spillage. In undertakings where spillage happens during high flow periods merely, spillage may be used for power coevals because it does non hold important impact3.1.1.3 Improved Turbine AerationTo cut down jobs of H2O quality is some undertakings, turbine replacing may be the solution. In the hot season, stratification occurs in most deep reservoirs. At the underside is a bed of low DO concentrated cold H2O, which when released through the turbines means the tailwater will hold deficient DO concentration. To ease this job, the H2O can be aerated prior to go throughing it through the turbine. Research has shown that in a few workss where the turbines have been constructed to entrain air into the flow when it passes through them, aeration of the tailwaters is sufficient and economical ; aquatic life and efficiency may nevertheless be affected. In such undertakings, upgrading of old turbines may enable the installing of self-aerating turbines that accordingly may increase the DO concentrations of the tailwater, finally profiting the environment.3.1.1.4 Changes in reservoir storage and flow releasesAs seen, to upgrade bing hydropower workss, methods like increasing the turbines ‘ flow rates or increasing or changing reservoir storage, done by increasing the dike ‘s lift and altering the H2O release periods during the twelvemonth severally, can be used, which may impact the downstream and reservoir H2O quality such as altering the concentrations of DO and temperature of H2O.3.1.2 Air QualityThe impacts of hydropower workss ascents on the air quality are normally impermanent and minimum, and usually occur merely because of dust emanations and other emanations that have escaped from the equipment used in upgrade undertakings that need major building. In fact, hydropower ascents may positively impact the air quality by minimising coevals utilizing fossil fuel.3.1.3 Aquatic EcosystemsIt has been established that the alterations that may happen during building and operation activities during bing hydropower works upgrades impact aquatic life. While minor ascents do non significantly impact the H2O quality, major ascents may ensue in dirt eroding and deposit, chemical and building oil spillage, and break of contaminated deposits, which may impact aquatic life. Increased temperatures and reduced concentrations of DO, hapless tailwater quality, could ensue because of fluctuations in flow releases during building. Furthermore, because of go throughing lowly DO concentrated H2O through a turbine, instead than sloping the H2O over a dike, there could be decreased aeration which besides affects aquatic life.3.1.4 Riparian and tellurian ecosystemsBreak to riparian w etlands and home grounds due to building activities is the chief cause of the impacts of bing hydropower workss upgrade on tellurian ecosystems. However, these impacts, which depend on the site or undertaking, are normally insignifanct and merely a few undertakings may do important impacts. Upstream tellurian home ground may significantly be lost through flood because of developments that comprise heightening lifts of the dike. Short-run deposit and fluctuations in flow agendas during building, in add-on to equipment replacing inside edifices, is non likely to hold long-run impacts on tellurian ecosystems.3.1.5 Diversion3.1.5.1 Construction impactsRecreational installations will non be significantly impacted by minor hydropower works ascents except during a little building period. Major ascents on the other manus may impact recreational activities. With the possibility of the deposit loads increasing as a consequence of creek beds and bank eroding, the affected H2O quality may impac t recreational activities such as H2O skiing, fishing, yachting, and swimming, among others ; such activities may besides be affected by rare minor spillage of oil and lubricators. During upgrade building, there may be dewatering and stagnancy because of controlled flow, which consequences in unwanted growing of algae and low concentrations of DO, accordingly impacting activities like fishing. Open stones, awful odors, loud blares, dust, harmful gas emanations, and eroded Bankss, among others may besides impact the aesthetics and therefore the recreational activities.3.1.5.2 Long term ImpactsDecreased aeration in downstream dike H2O is among the permanent impacts of hydropower works ascent on recreational activities. New turbines decrease the DO concentration, impacting aquatic life and finally fishing activities. Recreational activities may besides be impacted in undertakings where high flow-capable turbines are used because there will be different flow agendas for impoundings. Alt erations in the downstream flow graduated table or programming may impact the aquatic life, therefore impacting recreational activities.3.1.6 Dam Safety and FloodingConcerns for dike safety are normally as a consequence of major, non minor 1s, hydropower works ascents which involves promoting the reservoir degrees that consequences on more structural tonss on the dike, accordingly compromising the general dike ‘s safety factor. In most upgrade developments, deluging frights are uncommon. Still, among the methods of increasing coevals at bing reservoirs is to minimise flood storage so as to do more H2O available for coevals. There would, as a consequence of this lessening in inundation storage, be an increased concern for downstream implosion therapy ; different sites have different impacts and magnitude of the excess implosion therapy.3.1.7 Energy security benefitsAlthough it will non significantly to the U.S. ‘s entire power grid, the ascent of bing hydropower workss wo uld supply inexpensive and valuable energy signifier that is local and renewable, therefore is non susceptible to foreign ordinance or fuel scarcenesss. The value of energy ensuing from such ascents is felt more during peak demands, even though it may sometimes turn out undependable, particularly during low flows or when more flow releases are required to better H2O quality and aquatic life.3.2 Impact of new hydroelectric power at bing dikesWhen an bing dike is developed by put ining new hydropower workss, many advantages are realized, minus the several bad environmental effects experienced during hydropower development at new dikes. This is because at bing dikes, the impacts caused by stream ictus such as submerging of tellurian home ground, obstructor of fish migration, alteration in volume and timing of downstream flow, among others, have already been felt ; more impacts may still be felt during retrofitting.3.2.1 Water resources3.2.1.1 Construction ImpactsThere may be some imper manent impacts on H2O resources that result from the building activities during retrofitting. Erosion at the site of building and the accidental discharge of unearthed stuffs into the watercourse may do the tailwaters to hold sediment tonss. Furthermore, the building activities may do spillage of oil and perturbation and distribution of contaminated deposits present at a dike. These impermanent impacts normally end after building is complete.3.2.1.2 Change in flow release formsDue to alterations in release agendas of H2O in hydropower workss, the downstream may hold harmful effects like interrupting aquatic life, recreational activities, and increasing eroding of the bank. As such, flow alterations are normally prohibited because they may take down the dike ‘s capacity to run into its initial marks.3.2.1.3 Changes in tailwater quality due to alterations in release liftWater in a retrofit hydropower workss can be extracted from lifts separate from the initial impounding ‘ s backdown lift. During summer, the quality of H2O in deep storage reservoir normally fluctuates with lift. An impounding, with cold H2O normally holding low concentrations of DO in its lower lifts and warm H2O holding high concentrations of DO in the higher lifts, is caused by thermic stratification. In such graded impoundings where the bing release is through a wasteweir or high lift Gatess at the top, there would be fluctuations in downstream quality during hot conditions from high to low concentrations of DO and high to low temperatures when there is installing of a hydropower works retreating from low lifts. There is normally a high heavy metal concentration like Mg and Fe, irritant compounds, in yatter discharged from low lift. Rarely, shallow impoundings may besides hold stratified H2O quality.3.2.1.4 Change in reserve H2O quality due to alterations in release liftVariations in the backdown lift from a reservoir, in add-on to the impacts discussed before, may besides impact q uality of H2O in the impoundment upstream of the dike. A gate release replacing with a turbine consumption at even the slightest lift alteration for case may take down the volume of cold H2O on the reservoir ‘s underside and raise the warm H2O volume in the reservoir in hot conditions. These fluctuations may impact temperature of H2O, production of algae, concentration of DO, and other issues of H2O quality at changing times and sites in the reservoir. Reservoir simulation theoretical accounts are employed in the anticipation of the compound, unpredictable, and site-exclusive impacts. Changing the backdown lift may sometimes be utile for the H2O quality in the reservoir, and sometimes harmful.3.2.1.5 Nitrogen Super impregnationHydropower upgrade undertakings cause nitrogen ace impregnation and later the fishes ‘ gas bubble infection which causes the formation of gas bubble in a organic structure of the fish which may kill. Three conditions may ensue in the formation of n itrogen ace impregnation: when releases from the reservoir are really aerated, when air is entrained into severely constructed sluicegates, and when N saturated H2O from inside the reservoir is discharged to tailwaters. Nitrogen ace impregnation does non by and large have big impacts in hydropower development at retrofitted dikes.3.2.2 Air QualityAs has been established, impacts of air quality of retrofitting dikes are similar to hydropower works ascent ‘s local, impermanent and minimum impacts. Happening merely during building, effects may include get awaying dust emanations and equipment usage emanations and are by and large minimum compared with other emanations.3.2.3 Aquatic ecosystemThe aquatic resources during building from dike retrofitting are impacted the same manner as during ascent of bing hydropower workss. There is nevertheless greater opportunity for the impact on aquatic resources, by degrading the H2O and home ground quality, to be more, peculiarly from H2O deb asement, because of the major building in this option. Despite the already bing reservoir and the beings ‘ version to the H2O environment, get downing of hydroelectricity production may alter the releases ‘ volume and timing. Consequently, there may be instant and more terrible H2O degree fluctuations in the tailwaters and reservoir, which destroy critical shallow-water home ground for aquatic life. Furthermore, when lowly concentrated DO, cold, deep H2O is discharged from stratified reservoirs will degrade the quality of H2O of the tailwaters and negatively impact the ecosystem adapted to deep warm, extremely concentrated DO H2O releases.3.2.4 Dam safety and implosion therapy3.2.4.1 Dam safetyRetrofiting hydropower dike has a few dike safety concerns. Because building may necessitate removing of some of the bing dike ‘s parts, there is a possibility of the dike ‘s basis or construction weakening if improperly done.3.2.4.2 DelugingDesign-specific, the buildin g of hydropower workss at dikes with low-head may upsurge the implosion therapy upstream ‘s rate and graduated table. If there is the slightest obstructor in the flows ‘ way due to building, the upstream inundation lifts would increase.3.2.5 Energy security benefitsAlthough it will non significantly to the U.S. ‘s entire power grid, energy from retrofitting dikes would supply inexpensive and valuable energy signifier that is local and renewable, therefore is non susceptible to foreign ordinance or fuel scarcenesss. The value of energy ensuing from such an option is felt more during peak demands, even though it may sometimes turn out undependable, particularly during low flows or when more flow releases are required to better H2O quality and aquatic life.3.3 Impacts of coevals utilizing fossil fuelsMost of U.S. power production capacity is due to the usage of fossil fuels ( coal, gas and oil ) . The power that would hold been produced by hydropower is so got from th e usage of these fossil fuels.3.3.1 Water resourcesThe coevals of fossil-fuels can take to a figure of effects to H2O resources. In most instances fossil fuels workss are normally constructed following to big H2O organic structures to supply H2O for chilling or to thrust ahead as agencies of conveyance for the fuels. The building of these workss besides interferes with the land countries taking to eroding and as a consequence taking to residue tonss in the H2O organic structures. Coal excavation and transit are the chief effects of coal- power coevals to legion H2O organic structures. In the humid parts coal mines have for a long period triggered serious pollution of H2O organic structures due to altering of the river channels ( because of direct excavation effects, hydrologic alterations to watershed, and increased residue tonss ) and drainage of acids from mines. Although these impacts can be controlled, to a certain extent they can non be wholly avoided. In waterless countries, these effects are less compared to those in humid countries. However, impacts such as change of groundwater can happen. Even though, the transit of fossil fuels by flatboat on H2O resources can do minor impacts, other agencies of transit such as coal slurry grapevines, can ensue into terrible impacts on local H2O organic structures. The lavation of coal at the power works or mine to better its combustion or emanations qualities ; big sums of H2O are consumed every bit good as pollut ion as a consequence of these procedures. Water resources can besides be degraded due to production and transit of gas and oil used in the production of electric power. These effects can be due to offshore oil production and oil spills in the class of refinement and transit. The production of fossil-fuel power workss is the root to several pollution effects to H2O organic structures. Cooling H2O is required by these workss in the condensation of steam after it has been recycled in the boilers. The cooling H2O can be used one time and channeled to come up H2O or it can be recycled through the chilling tower let go ofing the heat out to the ambiance. Significant temperature addition and vaporization in the receiving H2O organic structure can besides be caused by chilling procedures. Water is likewise consumed by the chilling towers through vaporization and the discharge of blow down H2O, which contains higher concentrations of dissolved solids.3.3.2 Air qualityThe major beginning of air emanations is due to the usage of fossil fuels in power coevals as compared to the usage hydroelectric coevals. Some of these emanations include ; dust discharged from coal hemorrhoids and mines, vehicles used in excavation and transit of these fossil fuels, the storage and use of crude oil and gas besides release hydrocarbon emanations and emanations from burning. Air quality as an impact of fossil- fuel production is of the greatest concern as it leads to the emanation of burning merchandises such as S dioxide, azotic oxide, atoms and C dioxide. Approximately 70 % sulfur emanations, 40 % of azotic oxide emanations and 10 % of particulate emanations of U.S. are produced during fossil- fueled power production. With most emanations coming from oil and coal burning, natural gas- fuel workss have significantly lowered air emanations. The chief concerns are sulfur dioxide and azotic oxides ; they non merely affect human wellness but besides contribute to acidic rain and dry deposition. Particulates can likewise hold terrible effects on human wellness, conditions and visibleness. Carbon dioxide emanations are besides possible subscribers to planetary heating. Ever since the 1950s, a steady rise in the emanations of C dioxide has been experienced. Whereas about half of the emitted C dioxide released remains in the ambiance lending to planetary heating, the staying half is either dissolved into oceans or taken up by workss or sequestered.3.3.3 Aquatic ecosystemSeveral of the impacts due to the building and operation of fossil-fueled power workss to aquatic ecological resources are really different both in sort and magnitude to the impacts brought approximately by several hydropower replacements. Unless a chilling lake is created by the dodo fuel works, the loss of aquatic home ground will be relativity little, compar ed to those due to upgrading or retrofitting of already bing reservoirs. This will be much less compared to the sum of riverine home grounds that would be lost due to a new hydroelectric impounding. Entrainment, encroachment and chemical and thermic discharges are some of the effects brought approximately by the operation of a chilling system capacitor of a dodo works to aquatic beings. Large sums of solid wastes such as burning ash and scrubber sludge are besides produced by coal-burning power workss. If non controlled, leachates form coal and ash hemorrhoids can degrade the H2O quality every bit good as holding toxicant effects on the aquatic beings. Furthermore, aquatic communities over a big geographical country can see important H2O quality effects and habitat loss associated to the whole fuel rhythm ( coal and oil excavation, polish or cleansing, and ash deposition ) . Aquatic beings in widespread countries can likewise be affected by acerb deposition from fossil fuel workss.3.3.4 DiversionThe state ‘s uninterrupted dependance on fossil fuels as the chief beginning of production for electrical power has appeared to hold important effects on recreational avocations in assorted countries. During the air inversion episodes in some of the major metropoliss in the U.S. , air quality effects due to the burning of coal are already impacting people with respiratory complications who the usage some of these recreational resources. In New England and other parts of the U.S. , acidic depositions from coal burning is said to hold affected fishing in assorted lakes. Drain of acids from coal mines has non merely affect fishing but white water canoeing and kayaking, yachting, swimming, hike and the overall aesthetic qualities of watercourses in Appalachia and in other topographic points. Through the surface excavation of coal recreational chances such as hunting, hike and nature observation can be disturbed throughout the U.S. However, through renewal, these sites may heighten some of these recreational resources. Increased concentrations of nursery gases in the ambiance can besides convey with it impacts to recreational resources such as alteration in the precipitation measures and governments of a part, more serious or more perennial air inversions, raising or take downing of reservoirs capacities, legion or more terrible major storms in the coastal countries, rise in the sea degree, altering of wildlife home grounds, and change of wildlife migration waies and times. Any out-of-door recreational avocation will be significantly be affected by all these. The boring rigs near the refineries for gas and oil used in power coevals can likewise consequence in H2O quality impacts from rigs, oilers or grapevines which may take to occasional oil spills both onshore and offshore. Recreational activities such as fishing, yachting, swimming, and nature observation can besides be affected as consequence of these impacts. Refinery installations ( with both ocular and olfactive effects ) are frequently seen to be noxious topographic points doing them incompatible with recreational resources. Aesthetic enjoyment of such recreational resources can be reduced where there are grapevines. Drilling, production and other research activities due to increased used of gas and oil can hold possible negative effects on these diversion resources particularly in wildlife safeties and delicate offshore locations. In Western United States, in some of the comparatively pristine environment where natural gas desulfurization installations are located near the boring rigs ; ocular, audile and olfactive impacts could be produced where this gas is found. Activities such as hike, runing and nature observation could besides be affected.3.3.5 Energy security benefitsSupplies form Coal and domestic gases are considered to be unafraid energy resource suppliers. In the United States, coal is known to be the richest unrenewable energy resources. Although, fossil-fueled workss are considered to be extremely dependable, they can be besides be affected by terrible conditions conditions such as drouths ( that consequence into inefficient chilling doing it expensive for power production ) . Following the day-to-day rhythm demands, fossil-fuel power workss are non all that efficient. In the quest to extenuate this inefficiency, pumped storage hydroelectric power undertakings and gas turbine workss though less ef ficient are frequently used because the turbines respond rapidly to altering demands. Environmental impacts which involves air emanations both regional and globally and the high ingestion of H2O are some of the factors that limit the development of new fossil-fueled workss at assorted sites. 4.0 Decision

Free Essays on Leonin

Leonin Leonin was born in Paris, France in the year 1135 AD (Estrella, 2004). He had such a musical influence to the pioneers of our medieval time period even after his death in the year 1201 AD (Estrella, 2004). Leonin was even considered one of the greatest musical minds in the history of Western Music. He received his well earned education at Notre Dame Cathedral in Paris. Eventually, he served as a canon (Estrella, 2004). He was a French composer as well as poet (Estrella, 2004). Though his significance came from his work with music, his poetry was also well recognized. Though very little is known about the life and details of Leonin, the impact he made in the music world has lasted for ages now. The only writings on Leonin from his earlier life time, came from a later student at the Cathedral known as Anonymous IV (Estrella, 2004). This person is supposed to be an Englishman who left a treatise on theory (Estrella, 2004). Anonymous IV mentions Leonin as the great composer of the Magnus liber (Estrella, 2004). One of Leonin’s greatest achievements was the creation of the Magnus liber organi (The Great Book of Organum). The Great Book of Organum, is a cycle of two-part Graduals, Alleluias, and responsories for the entire church year (Grout, p 77). Unfortunately, the Magnus liber does not exist in its original form (Grout, p 78). . There are manuscripts preserved in libraries at Florence, Wolfenbuttel, Madrid, and elsewhere (Grout, p 78). There is no knowledge of exactly how much of the Magnus liber Leonin composed (Grout, p 79). . Organum is the earliest form of medieval polyphonic music (Estrella, 2004). Before any of the works of Leonin, there is no evidence of any type of comprehensive rhythmic system (Estrella, 2004). Leonin improved organum by adding rhythmic structure to the tenor (Grout, p 79). This rhythmic system is based on six different rhythmic patterns known as rhythmic modes (Estrella, 2004)....

Sample Essay: Instagram – the Vanity Fair of Modern Pop Culture Try to guess which feeling is indispensable for human nature for many centuries? Here is the prompting: â€Å"What a nice chariot has this patrician?!†; â€Å"The horse of this knight from Birmingham is amazing!†; â€Å"The Louboutin shoes of this girl can be compared only with her bag from Prada!† So, this feeling is envy. The commandment  «Love your neighbor† was transformed into â€Å"Discuss your neighbor† and â€Å"Compare yourself with your neighbor†. In the modern world, it’s much easier to follow this rule. One doesn’t need to go to the knight tourney or ball as now it’s quite enough just to take a photo with your â€Å"metal horse† and share it with others in social networks. The illusion of the photo works perfectly: other people believe that the person on the photo is the lucky one, and their lives are so boring in comparison with him or her. They say that Facebook is for clever people, Twitter – for lazy and Instagram – for attractive. The last one became a real vanity fair where everyone can boast with something he or she is proud of new Botox lips or appetizing hamburger. That’s the new type of a superhero – the â€Å"example-person†. Such a person doesn’t have some supernatural powers and lives only on the screens of the smartphones, gathers â€Å"likes†, and serves as an example of a successful life about which all average users should dream about. We try to look like this person and get upset when understand how difficult it is. However, don’t trust everything from the web. In autumn 2015, one of the superheroes of our time became sick and tired of everything. 19 years old Australian Essena ONeill – the owner of the Instagram account with half a million of followers, left the social network and shared the truth which was hidden behind each of her photos. Essena became popular in a simple way: selfies, photos of fashionable looks and sportive body gathered a lot of followers. After this numerous brands started to pay her for selfies and hashtags in their products. Sometime later, she opened the truth – all these photos weren’t real. The girl could make hundreds of photos to get one perfect. Social networks aren’t real life. Be careful when admire such photos and ask yourself what was the aim of this or that photo. Hanna Krasnova, the professor from Berlins Humboldt University, states that photos in Instagram demonstrate success, welfare, and happiness. They make us compare our own achievements with the achievements of others. It may even cause low self-esteem. Krasnova provided a research where she gave the definition to the phenomenon of â€Å"Vanity fair†: When you see some nice photos of your friend – the only way of compensation is self-presentation – you post even better photos; your friend sees them and posts better photos again. It’s a never-ending circle: self-presentation causes self-presentation, and the world of social networks becomes even further from the real world. The researches confirm that social media possession makes us unhappy. More and more people worry because of the decision which photo to post doubting whether it is perfect or not. â€Å"Consume responsibly† – such a note should be added not only to beer bottles but to social networks as well. Hundreds of followers and â€Å"likes† are often only the sign that the person has mastered the commandment  «Discuss your neighbor†. The happiness which we see on the Instagram photos is not always present in the real life. References: Trompenaars, F., Hampden-Turner, C. (1997) Riding the Waves of Culture.

15 Compare and Contrast Essay Topics on the Changes of Women’s Role in Vietnamese Society

15 Compare and Contrast Essay Topics on the Changes of Women’s Role in Vietnamese Society If you are tasked with writing a compare and contrast essay on the changes of women’s roles within Vietnamese society, there are many things that you might want to cover. The first step is of course, selecting the topic that most speaks to you. Your goal in selecting a topic is to pick something that you are interested in. The more you are curious about a particular change that has taken place in that society, the easier and faster the research and writing process will be for you. You will also be able to put forth your personal passion for the topic into the work, something that will show through to your reader. When writing a compare and contrast essay, you can take any of the key issues you want and compare them to other issues, contrast them to other countries, to other services, or even to different ethnic groups. One of the main areas for discrepancy among any of the changes that have taken place with regard to women’s roles is that which exists between rural and urban women, as well as women who are of a minority ethnically or a majority ethnically. Almost all areas you might want to review can be compared or contrasted in these lights. Below is a list of some interesting facts that you might be able to use in your compare and contrast essay: Today, women in Vietnam are represented widely in higher education, within the public sector, and in non-government organizations. There is still a glass ceiling for women, but they can nonetheless gain leadership or managerial positions. Women are free to travel in urban areas without many restrictions on the people with whom they can interact, where they are allowed to go, or how they must dress. Women today take credit for up to 50% of the workforce and labor growth of the country, particularly in the shoe, garment, and electronics factories which make up a substantial part of that workforce. Women have migrated from poorer, agricultural communities to work in factories that are unhealthy and overcrowded, but recently liberalized trade has opened up new markets and allowed women to start their own businesses. There are still gaps between men and women with regard to general health, economic performance, and educational attainment, but each of these three gaps has narrowed over the last few years as statuses for women in the country have improved. 60% of the adult women in the country are economically active and the mean hourly wages are between 85-90% of that earned by men. This compares to women having an average of just one year less of formal education compared to men. Additionally, women are more likely to live in poverty, to have been sick at least once over the last twelve months, or to live with disabilities. While there are many changes taking place in urban areas for women, the gender gaps remain at their widest in rural regions or among ethnic minority groups. Changes have taken place with regard to the access to credit made available to women. Today new banking interventions now allow private credit institutions the ability to offer credit to small and medium sized businesses, owned by men or women. This credit is now being offered by the State Bank of Vietnam making it easier for those businesses operating within an international framework. Trade functions as one area that offers women clear opportunities, but there is a lack of targeted support for those businesses owned exclusively by women which is why it has not been used to its highest capacity. Technical support has now been made available for those women who own businesses. There are local business associations in smaller areas comprised of the women who are starting businesses in those areas, but there is still no single beacon of service or support for women in the workplace. Labor conditions are different compared between rural and urban areas, as well as between the service, industrial, and agricultural sectors. These items are also influenced by the minority status of the women, whether or not they have disabilities, and their geographic location. Women in poorer areas often lack trade unions or political stability which results in better labor conditions or more opportunities for advancement. Vietnam recently became part of the World Trade Organization (WTO) which means its citizens can now participate in regional trade and use legal frameworks that are pre-established. Overseeing this is Ministry of Trade which is overseen in almost all of its highest positions by men. Women are starting to gain positions within this department. Previously, businesses and enterprises owned by women were underserved and lacked access to the same opportunities as those owned by men. They were also subject to higher competition from businesses owned by men. The government does not maintain records of those businesses owned by women which makes it difficult, at best, to decide how well target programming is working, but with new partnerships with the WTO, this will be made easier and more regulated. Gender equality remains a core legal principle and as such gender bias is not apparent as a barrier to using formal dispute resolution processes in any legal problem. The reality, nonetheless, is that very few women actually use alternative dispute resolutions or the official court systems to resolve their disputes. There is a cultural aversion to the engagement of public disputes. What’s more, many businesses within the country lack formal written agreements, something which would be necessary for formal dispute resolution processes. In the country today, two thirds of enterprises in urban areas are owned by women and in rural areas nearly three quarters of enterprises are done by women. Many of these enterprises are small and lack information necessary to use formal dispute resolution processes. As a result, there is a risk that poor women, as well as those living in rural areas, and who are part of an ethnic minority do not have equal access to information about legal rights. These facts are very important for you if you want to deal with this issue in your compare and contrast essay writing. So, don’t forget to look through them before completing your writing assignment.

Measured Building Survey Essay Example | Topics and Well Written Essays - 2000 words

Measured Building Survey - Essay Example It comments on the current state of all parts of the structure. These parts of the building are physically inspected but limited to the scope of services offered by the building surveyor. Major defects survey is also referred to as main elements survey. For this type of survey, focus is on the main parts of the structure. Inspection and report concentrate on selected areas like roofs, floors, ceilings and windows. The home buyer report survey is standardized, covering main aspects of the structure but not detailed. It is restricted only to accessible parts of the structure. Specific survey narrows down the scope of survey to particular parts of a property depending on the owner’s knowledge (Douglas, and Noy, 2011 P.8). In most cases, building survey is advocated for buildings that lack documentation or they cannot be used. However, it assists in developing reliable and an accurate document and or a verification of an existing document. This makes building survey an essential a ctivity in the planning process as well as providing detailed information for further planning activities. The methods of survey used are: field sketch, dimensioned sketch, tape and offset survey or extended baseline survey and plane table and alidade survey. The best survey is achieved through a combination of these three methods (Scotland’s Rural Past, 2005, p.6). Sketches, plans and accurate geometric data together with information gathered from survey are combined and structured properly. These parameters are used to derive an actual design and planning process. The first step towards building survey is taking of measurements on site by use of conventional equipment like measuring stick or optical distance meters. Sophisticated surveying techniques like tachometry, laser scanner and photogrammetry are used (.Douglas, and Noy 2011, p.34). The next steps involve combining the measurements to produce details, sections and elevation of the property that are derived from plan. According to RICS (2007, p.30), any residential property is defined by linear measurement but not from floor area. Measurements are taken from a point not greater than 1.5 meters above the floor and skirting board. Recesses, bays and the like are excluded in the measurements taken. The room area should include kitchen units, cupboards and the like although it must be identified separately. When taking garage measurements, the span between main walls faces internally are of importance. Risk Assessment Some of the factors to consider in risk assessment are: Critical areas of concern in relation to residential property. Considerations from building codes and seismic zones. How to get information in relation to resources, skills and ability to investigate what you are not familiar with. Commitment to the task of checking and confirming details in the design. From the plan, elevations and sections developed from survey, the form, dimensions, orientation, natural lighting, ventilation an d spatial organizations of occupants assist in redesigning a new property. Issues required in designing of a house and their relevance as well as recommendations is considered. This is what is called risk assessment that aims at construction of safer homes. The main risks for property are; fire, harsh environment, floods, cyclones and earthquakes. The main services are drainage, gas, electricity and water. The

Microeconomic Essay Example | Topics and Well Written Essays - 1500 words

Microeconomic - Essay Example This academic paper will be focused on the logic behind warranties as signal of quality as well as what limits the attractiveness of warranties as signals for high-quality firms. Grossman (1981) argued that indicating enhanced efficient functioning of a perfectly competitive market in a situation where there is information deficiency. Warranties offered by most production companies are considered common types of signal sent by high-quality production companies. This is at reducing consumer’s quality doubt and information gaps in the product’s quality. Quality has been used to refer to observable and unobserved product characteristics in terms of product performance and durability. The common assumption is that firms producing low-quality products find it very expensive to offer a warranty. This product assumption makes offering of product warranty a credible signal of unobservable product performance and durability among many other features. In the production industry, product failures are highly linked with product quality and workmanship hence the cost of offering the warrant will be higher for poor quality products. As a result of innovation and technological advancements, the information asymmetry between consumer and manufacturer is great. This comes about due to an increase product modifications and releases on an annual basis. In the situation of new products, consumers have very little information on product information and quality due to the unavailability of past experiences and third party reviews. The injection of costly warranties in asymmetric information implies that warranties serve as pertinent projections of product quality in the production sector. The primary objective of all businesses remains profit-making through cost minimization and revenue maximization. In case the producers manufactured goods with high chances of product failures, they will be forced to incur high costs through repair and repl acement which will

Does football promote freindship or enmity Essay

Does football promote freindship or enmity - Essay Example Apparently, most soccer fans prefer watching matches in social places such as clubs, restaurants or at home as long as they are in the company of people who have interest in soccer. Consequently, a bond is created between these people, who may be strangers, since they will have a common topic for discussion throughout the 90 minutes. In this context, it is true to say that football facilitates and enhances the creation of friendships between strangers however short lived they might be (Foer 39). Similarly, football promotes friendship in terms of suppressing racial mentalities that promote discrimination. The world cup for example sets an international stage for teams from different countries, some of which have been in conflict with each other for a long time due to political or ideological differences. Whenever these teams are playing, the people watching get to forget their differences, especially due to the fact that there are high standards set for officiating matches such that every participant feels comfortable with the results. This is made better by the display of sportsmanship by footballers whereby they shake hands even after one of them has committed a foul against the other. By doing so, they portray a high level of emotional intelligence which becomes a good example for those who are watching.

Men and women often tend to carry a magazine with them to pass their time. Today, we have magazines covering the latest fashion, Hollywood scandal, the glitz and the glamour of celebrity lifestyles, sports and fitness, just to name a few! The ‘magazine business’ is a multi million dollar business simply because it is affordable and also produced on a monthly basis in general. Although men and women buy and read magazines, it is indeed safe to say that most if not all magazines covet the â€Å"perfect woman† to adorn its pages, sell its products and lure customers to take the bait.In this paper we will look at how popular magazines focus on spreading the image that in order for a woman to look beautiful, she must look a certain way and follow a particular style. We will examine the consequences and effects that this has had on women, look at why there is such a great demand for scantily clad women and why does sex sell so quick!We will also look at why Caucasian women are more in demand to pose for magazines and be their glamour girls more than any other race in the world.I will conclude this paper by examining the cause and effects that magazines have on women and how can one be wise enough not to be snared or captured by the glitz and the glamour that these magazines so readily display! display! Magazines: Their Powers of Persuasion One of the strongest forces that magazines use is 'The power of persuasion'. The power of persuasion goes to work on the reader as soon they pick up the magazine. It was Gloria Steinem who said "Most women's magazines simply try to mold women into bigger and better consumers". And that's the reason why we see magazines such as 'Cosmopolitan', 'Vogue' 'Glamour' etc having celebrities and models adorn their pages and promote their products. Through them they convey to the world, that in order to be like them and look like them you must follow them. Most magazines encourage its readers to go on diets to make them look thinner, try plastic surgery so that they can fix any 'flaws' that they have and urge you to try their beauty secrets and vitamin pills so that you can not only look good but also feel good! These magazines make sure they feature a list of their products that will help you achieve your goal! The power of persuasion works through the medium of suggestion and this is one of the biggest reasons why Magazines have such a tremendous impact on the world at large! Magazines: The Pictures they Paint The front covers of most magazines have pictures of celebrities and models that are scantily clad and in a pose that is both suggestive as well as provocative. On the front pages are alluring captions which act as powerful tools of persuasion and immediately go to work on the readers mind. The November issue of Cosmopolitan has the words "Get a sexy Bod" in bold letters on its front page, Vogue has Jennifer Aniston on its front cover with a bold lettered caption "The Shape Issue" and Muscle Mag has wwe diva Candice Michelle on its cover to promote fitness and subtly suggest how one can and should have a body like Candice. The message that is being sent across to every woman through these magazines is very subtle but yet perfectly clear. They suggest that if you want to look glamorous, be in sync with the latest style and be the center of attention, you must do whatever it takes, buy whatever it

English Education - Essay Example An interesting dimension to this trend in education is how students choose their schools. One would find, for instance, that parents take a greater role in their children’s schooling, especially in regard to university and skills education, in their desire for a better life and chances for their children. For example, Doria, (2005) talked about the case of Australia: A â€Å"factor that influences students to study in Australia is that the country is comparatively safe, it has a clean environment, and living here is affordable.† (20) Students are swayed by attractive university marketing, say, one that promotes the high quality of education and the relative appearance of the school campuses. Scholarship offerings, which the U.S.A. is known for, is also important factor in the students’ choices of schools. (Doria 2005, 9- 20) Another issue in studying abroad concerns immigration opportunities. For parents, if their children study, say, in Australia, there is a possibility of obtaining Australian citizenship for all families and that, in itself, is a worthy return for the investment. In addition, many students look for career opportunities by studying abroad where they can develop their mental abilities, cultural perspective and in learning another language. Some of them want to get away from restrictive customs (Doria 2005, 19). The result of this new phenomenon in education is that overseas students are forcing changes in the curricula of universities by requiring emphasis on the methodology of teaching, special programmes and also result in confronting the slowing down of communication classes due to language-skill and cultural barriers. In preserving the quality of education including improving the standard of English courses, universities have to focus on developing teacher abilities and changing styles of educational

France increasingly eclipsing Spain as the favorite destination for UK Essay

France increasingly eclipsing Spain as the favorite destination for UK property buyers to invest - Essay Example If you thought the overseas property market is dying due to the recent financial upheavals, then think again. The most-recent and the biggest-ever study of overseas holiday homeowners has revealed that in spite of price falls ranging from ten percent in France to fifty percent in Spain, the number of Britons purchasing homes in other European countries has actually increased in course of the recent recession. In 2006 for instance, some 385,000 Britons owned holiday homes in other European countries, a figure that has since increased tremendously to as high as 430,000 by 2010 (Avella, 2004). Reflecting travel and tourism trends, investments in long haul holiday destinations like Caribbean, Asia, and Africa, which generally offers warm climates enable holiday home owners to benefit from longer visiting seasons and therefore, longer rental periods. Correspondingly, holiday homeowners have been taking advantage of the short-term letting in the year-round city-break market (Keller, & Bieger, 2008). However, compared to inland nation and urban locations, it is beach holiday destinations that seem to attract most second home investment. Motivated both by the letting potential and their own holiday plans, over half of UK overseas properties owners have bought homes in coastal areas as can be demonstrated by the graph below. Due to this changing environment in the property market in Europe, we are going to explore the attractiveness of a number of countries in terms of overseas property investment. In this case, we will focus on three European countries namely; France, Italy, and Spain. ... currently, we will be able to advice our clients on those countries (Italy, France, and Spain) on whether to continue holding on to their property investment or to sell them. Sample Framework: In coming up with appropriate information to help ascertain which among France, Italy, and Spain is a better property investment destination at the moment, we will be required to ask property investor in UK a number of a question on each of these countries and score them on a 5-point Likert Scale before using a Frequency distribution as a quantitative technique to draw a conclusion. Sample Size and Technique: The sample of this research will be a total of ten property investors residing in UK. The research will make use a number of sampling techniques namely; a. Random sampling; questionnaires will be issued at random to people who have properties in all or any of the three countries (Italy, France, and Spain), something that is expected to ensure that each property investor residing in the UK is accorded an equal chance of participating in the research. b. Convenient sampling; because of the difficulty that might be involved in identifying a UK citizen who is not only conversant but also up-to-date with overseas property investment, it might be a bit difficult to achieve randomness in this research. However, in order to bypass this handicap it therefore becomes necessary to issue a questionnaire or hold an interview with any UK property investor that the researcher bumps on, which is a measure that will help the researcher achieve randomness in this research. c. Purposive sampling; because of the complexity of some of the issues, reaction of some research questions will require the input of particular property investor. This therefore calls for an approach that will see to it

La-Mg-Ni Based Alloys

La-Mg-Ni Based Alloys Abstract: Degradation behaviors of La2MgNi9, La1.5Mg0.5Ni7 and La4MgNi19 alloys were studied. The results indicate that severe pulverization and corrosion are important factors leading to the capacity deterioration. However, it is puzzled that corrosion of the electrochemical cycled alloys is aggravated, which is inconsistent with the result that La2MgNi9 present poor cycling stability andalso the assumption that alloy with high Mg content is easy to be corroded. Then, the intrinsic anti-corrosion and anti-pulverization characteristics were mainly focused in the first part of this work. Immersion experiments demonstrate that the Mg-rich phases are more easily to be corroded. The intrinsic anti-corrosion resistance of the three alloys presents an improved trend which is inversely proportional to the abundance of the Mg-rich phases. However, the intrinsic anti-pulverization ability just presents an inverse trend, which is closely related to mechanical property of the phase structures. LaNi5 with the highest hardness is easy to crack, but the soft (La,Mg)Ni2 is more resistant to crack formation and spreading, suggesting a possibility to improve the anti-pulverization ability by adjusting the phase constitution. In general, the weaker corroded extent of La2MgNi9 in the electrochemical test is attributed to its better intrinsic anti-pulverization capability though the intrinsic anti-corrosion of La2MgNi9 is worse. As to La4MgNi19 which possesses excellent intrinsic anti-corrosion resistant, enhancement of the anti-pulverization ability is the key issue to improve the cycling stability. 1 Introduction Superlattice La-Mg-Ni based hydrogen storage alloys have received substantial attentions over the last decade because the excellent electrochemical performances used in nickel/metal hydride (Ni/MH) battery [1-5]. Up to now, A2B7 type alloys have been successful developed for the practical use [3]. However, AB2 and AB3 type alloys present poor cycling stability though the theoretical discharge capacities are higher than A2B7 type alloys [6-8]. In addition, A5B19 type alloys have been reported to possess good electrochemical performances, but they still need improvement to meet the practical application, especially on the cycling stability in the long-term reversible cycles [9-10]. It is well accepted that electrochemical capacity decrease of the metal hydride electrodes is caused by both the physical and chemical degradation [11-12]. In La-Mg-Ni system, factors affecting the capacity degradation were emphasized on pulverization and corrosion during the charge/discharge cyclings [13-17]. Corrosion leads to damage and disappearance of the phases which possess considerable hydrogen storage capacity. It has been reported that La-Mg-Ni alloys are easily to be corroded into La(OH)3 and Mg(OH)2 [13-15]. And these kinds of corrosion products are loose and passive which cannot protect the matrix for further corrosion [15-16]. Severe pulverization of La-Mg-Ni alloys during cycling had also been reported in many works [13-17]. Pulverization makes fresh surface of the electrodes alloys continuously exposed to the electrolyte and dramatically improves development of corrosion. Liu et al. classified the degradation process of the La-Mg-Ni-Co alloy into three stages: the pul verization and Mg oxidation stage, the Mg and La oxidation stage and the oxidation and passivation stage [14]. In addition, capacity degradation of the metal hydrides is closely related to the structural changes during absorption/desorption cycling. Our previous works demonstrated that transformation from crystallinity to amorphous viz. hydrogen induced amorphization (HIA) of La-Mg-Ni alloys occurred during the hydrogenation cycles and remarkably worsens both the gas-solid and electrochemical storage performances [18-19]. Understanding of the degradation mechanisms is the precondition for improvement of the cycling stability of the La-Mg-Ni based alloys. Several compounds including AB2, AB3, A2B7 and A5B19 type phase exist in this system, and the alloys usually present multi-phase microstructure. Though quiet a number of efforts have been applied on the degradation characters of the La-Mg-Ni based alloys, these works mainly focused on the overall capacity deterioration behaviors of the alloys. Diversity of the degradation characteristics of various compounds in this system is also lacking. In the present study, degradation mechanisms of three typical La-Mg-Ni alloys: La2MgNi9, La1.5Mg0.5Ni7 and La4MgNi19 have been systematically investigated. In the first part of this work, corrosion and pulverization behaviors of the alloys, especially the intrinsic characteristics of the AB3, A2B7 and A5B19 type La-Mg-Ni phases during absorption/desorption cycling were generated. In a following paper, HIA and its in fluence on the hydrogen storage properties are discussed. 2 Experimental materials and methods 2.1 Alloy preparation The as-cast La2MgNi9, La1.5Mg0.5Ni7 and La4MgNi19 alloy was prepared by induction levitation melting under argon atmosphere. The as-cast alloys were remelted twice for homogeneity. Appropriate excess of Mg was added in order to compensate for the evaporative loss of Mg during melting. Then the as-cast La2MgNi9, La1.5Mg0.5Ni7 and La4MgNi19 alloys were annealed at 1143, 1173 and 1193 K respectively for 6 h protected in argon atmosphere. 2.2 Characterization The sample was fine polished and then etched using a mixed etchant (including water, ethanol, acetic acid, picric acid, nitric acid and hydrochloric acid) at 343K. Then metallographic microstructure of the alloys was observed using a laser scanning confocal microscope (LSCM: Olympus-OLS4000). Phase constitution of the alloys was also characterized by a scanning electron microscopy (SEM: FEI-Qanta 400) under backscatter electron mode (BSE) applied on the unetched samples. The chemical composition of various phases was studied by energy dispersive spectroscopy (EDS) equipped in the SEM. Crystal structures of the alloys were measured by an X-ray diffractometer (XRD: Bruker-D8 Advance) with Cu KÃŽÂ ±1 radiation. Micro-morphologies and selected area electron diffraction (SAED) were applied by means of a transmission electron microscopy (TEM: JEOL-2100 and FEI-F20) to examine the microstructural and crystallographic information. TEM samples were firstly crushed the bulk into fine powder , and then ultrasonic dispersion was performed in ethanol for 1800 s. Several drops of the mixed liquid were laid on a carbon membrane support on the copper grid, and dried in a vacuum oven. Particle size of the cycled alloys was tested by a laser particle size analyzer (Malvern-Mastersizer 3000) where the alloy particles were dispersed by absolute alcohol. Oxygen content of the electrochemical cycled and immersed alloys was performed on a nitrogen/oxygen tester (NCS-ON3000). Before the oxygen test, samples were immersed in deionized water for 24 h, then washed using absolute alcohol twice to remove the residual KOH, and dried in a vacuum drying oven. 2.3 Hydrogen storage properties Gas-solid cycling and PCT isotherm measurement were carried out by Suzuki -2SDWIN PCT system at 303K (Sieverts type). Before the PCT analysis, sample was activated as follow: evacuated at 473 K for 2 h, placed to 303K, hydrogenated under 3Mpa H2 (Purity 99.999%) pressure for 5 h, evacuated at 573 K for 2 h again. Each cycle consists of absorption at 2MPa for 600s and desorption by evacuating at 298K for 1200 s. For the electrochemical measurement, the alloy particles (40-50 µm) were mixed with carbonyl nickel powder in a weight ratio of 1:5 and cold pressed to form a pellet about 1g firstly. The pellets were then packed in a Ni foam substrate spot-welded with a Ni strip. The simulated three-electrode cell including a working electrode (metal hydride), a counter electrode (NiOOH/Ni(OH)2) and a reference electrode (Hg/HgO) was installed. Before electrochemical test, the alloy metal hydride electrode was immersed in 6 M KOH aqueous solution for 1d. The measurement to get the maximum capacity and cycling stability was to charge at current density of 105 mA/g for 4h followed by a rest of 10min, then discharged at the same current density to the cut-off voltage of -0.6 V. 3 Results and discussions 3.1 Microstructure and hydrogen storage performances LSCM and BSE micrographs of the three alloys are shown in Fig.1. Four contrasts can be detected in the La2MgNi9 alloy. The chemical quantitations of various contrast from EDS analysis are listed in Table 1, from which the four phases are speculated to be (La,Mg)Ni2, (La,Mg)Ni3, (La,Mg)2Ni7 and LaNi5. Five crystal structures including CaCu5-type, MgCu4Sn-type, PuNi3-type, Ce2Ni7-type and Gd2Co7-type are identified in XRD profile of the La2MgNi9 alloy, as shown in Fig.2. The structural parameters and phase abundance are refined and listed in Table 2. The results are in consistent with the metallographic observation that the main phase is (La,Mg)Ni3, then (La,Mg)Ni2and (La,Mg)2Ni7, but content of LaNi5 is rare. In case of the La1.5Mg0.5Ni7 and La4MgNi19 alloy, metallographic and XRD characterization indicate that (La,Mg)Ni2disappears, (La,Mg)5Ni19 emerges and LaNi5 increases with elevation of the B-side stoichiometry. The main phase of the La1.5Mg0.5Ni7 and La4MgNi19 alloy is (La,Mg)2Ni7 and (La,Mg)5Ni19 respectively, and the structural parameters and phase abundance are also listed in Table 2. Fig.3 displays P-C-Tcurves of the alloys, and the detailed data are given in Table 3. Theoretically, hydrogenation capability increases with reduction of the B-side stoichiometry in the La-Mg-Ni based alloys. However, the maximum hydrogen absorption content of the La2MgNi9 alloy is slightly lower than the La1.5Mg0.5Ni7 alloy. It is ascribed to the fact that some (La,Mg)Ni2 which can hardly absorb and desorb hydrogen at room temperature [8], existing in the La2MgNi9 alloy. The three alloys have analogic hydrogen absorption plateau. But both the desorption pressure and the reversible hydrogen capacity elevate with increase of the B-side stoichiometry of the three alloys. Reversible hydrogen capacity of the AB3-typed La2MgNi9 alloy is only 1.15 wt%, and the hysteresis effect is more evident than the other alloys. Electrochemical discharge curves and performances of the alloys are shown in Fig.4 and Table 3 respectively. Discharge capacities of the La2MgNi9 and La4MgNi19 alloy are lower than the La1.5Mg0.5Ni7 alloy. The lower discharge capacity of La2MgNi9 is due to the weak reversible hydrogen storage capacity. As to the La4MgNi19 alloy, it is attributed to high abundance of LaNi5 which is unsuited for the electrochemical application without alloying [20]. Furthermore, La1.5Mg0.5Ni7 presents better cycling stability than the other two alloys. Capacity retention after 100 cycles of the La2MgNi9 alloy is similar with that of the La4MgNi19 alloy. 3.2 Degradation characteristics after electrochemical cycling From morphology and EDS results of the alloys, it is clear that pulverization and corrosion have occurred after electrochemical cycling by 100 times (only La2MgNi9 alloy presents in Fig.5). XRD analysis shows that La(OH)3, Mg(OH)2 and La2O3 appear in the cycled alloys, as displayed in Fig.6. Likewise, morphology and SAED analysis of TEM confirm existence of La(OH)3 combined with La2O3 (stick-like), Mg(OH)2 (needle-like) and MgO (particles), which are marked with 1, 2 and 3 respectively as illustrated in Fig.7. The results are in consistent with the other literature studied on the corrosion products of a La1.5Mg0.5Ni7 alloy [21]. Detailed determinations of TEM are provided in the supplementary information (Fig.S1-S3). In addition, size and amount of La(OH)3 and La2O3 are obvious than that of Mg(OH)2 and MgO, indicating that corrosion of La is significant in the electrochemical environment. Mg(OH)2 and MgO are close to the alloy surface but very loose. It agrees well with the previous works that corrosion products of Mg are gel-type and cannot form a solid protection layer for further corrosion [15-16]. Compared among the three alloys, it is noteworthy that corrosion productions of the La2MgNi9alloy are less than the other alloys (see in Fig.6). Identically, oxygen contents of the electrochemical cycled alloys follow the order that La2MgNi9 1.5Mg0.5Ni7 4MgNi19, indicating that the corroded extent are aggravated (see in Fig.8). It is puzzled that the result is inconsistent with the electrochemical performances that La2MgNi9 possesses poor cycling stability. It also disagrees with the consideration that high Mg content is harmful to the corrosion resistance in La-Mg-Ni based alloys [22-24]. In order to comprehend this fact further, the intrinsic anti-corrosion resistance of the three alloys was investigated next. 3.3 The intrinsic anti-corrosion properties To avoid impacts of pulverization on the corrosion behaviors, the alloy particles with the same diameter (around 40 ÃŽÂ ¼m) were immersed in KOH solution at 60  °C for 15 d. Then the morphology, phase structure and oxygen content were measured for characterization of the intrinsic corrosion behaviors. SEM micrographs and EDS analysis of the alloy particles illustrate that severe corrosion occurred after immersion, the typical results are shown in Fig.9 (only La2MgNi9 alloy particles are given here). Compared to the electrochemical cycled alloys, the stick-like products which have been confirmed as composite of La(OH)3 and La2O3, are remarkable in the immersed samples which is due to aggravated corrosion at higher temperature. XRD profiles identify that the corrosion products are mainly La(OH)3, but La2O3 cannot be detected in the immersed alloys, as shown in Fig.10. Coincidently, SAED by TEM found that the stick-shaped phase is single-phase La(OH)3, as shown in Fig.11. The result suggests that La2O3 transforms to La(OH)3 during evolution of the corrosion process. Besides, Mg(OH)2 and MgO are also found existing in the immersed samples, and their morphologies are same with that in the electrochemical cycled alloys. However, Mg(OH)2can only be detected in La2MgNi9 from the identifications of XRD, indicating that corrosion of Mg is violent in La2MgNi9. Fig.12 is the oxygen contents of the immersed alloys, from which severity of corrosion of the three alloys are La2MgNi9 > La1.5Mg0.5Ni7 > La4MgNi19. To provide detailed information of the relationship between the corrosion behaviors and phase constitution, immersion test applied on the massive samples has also been studied (the condition is same with that of the powder samples). Fig.13 shows the SEM-BSE micrographs of the immersed samples (only La1.5Mg0.5Ni7 alloy are present here). Obviously, the corroded extent is inhomogeneous which is considered to be caused by differences of the anti-corrosion capabilities of the various phases. EDS analysis on two regions with diverse corrosion grades (as marked with 1 and 2 in Fig.13) shows no Mg but less O existing in region 1. Whereas, more Mg and O are detected in region 2 with severe corroded extent than region 1. Likewise, EDS-mapping indicates that the region possessing more Mg presents richer O, as shown in Fig.14. Similar result is more evident in the as-cast alloys, which is attributed to the inhomogeneous chemical composition and microstructure of the as-cast alloy, details can b e seen in the supplementary (Fig. S4 and S5). The aforementioned results demonstrate that the Mg-rich phases are easy to be corroded in the alkaline solution. It has been well demonstrated that Mg solubility in La-Mg-Ni alloys follows the order that (La,Mg)Ni2> (La,Mg)Ni3 > (La,Mg)2Ni7 > (La,Mg)5Ni19 > LaNi5 [25]. Thus the intrinsic anti-corrosion resistances of various phases in the La-Mg-Ni system are considered to be according with the inverse trend. This result is in agreement with several works where AB2and AB3 type La-Mg-Ni alloys have suffered serious corrosion after electrochemical experiments [8, 23-24]. The tendency is also exactly identical with that the anti-corrosion resistance is inversely proportional to the abundance of the Mg-rich phases. La2MgNi9 presents worse anti-corrosion capability because contents of the Mg-rich (La,Mg)Ni2and(La,Mg)Ni3 arehigher thanthe other two alloys. However, trend of the intrinsic anti-corrosion resistance is opposite to the corrosion extent of the three alloys after electrochemical cyclings. Concern to the fact that corrosion extent of the electrode alloys is also closely related to severity of pulverization during the electrochemical charge/discharge process, the pulverization properties of the alloys are carefully characterized then. 3.4 The intrinsic anti-pulverization properties In order to avoid influence of the additives in the electrochemical test on characterization of the intrinsic pulverization behaviors, the alloys are gaseous hydrogenated and dehydrogenated for 30 cycles. Morphology observation indicates that remarkable pulverization has occurred where decrease of the particle size and emergence of cracks can be seen clearly in the cycled alloys, as shown in Fig.15 (only La2MgNi9 alloy are present here). Then the particles sizes before (Sb) and after (Sa) cycling are measured and the size retention is calculated by Sb/Sa. It (Fig.16) shows that severity of pulverization for the three alloys are La2MgNi9 1.5Mg0.5Ni7 4MgNi19, which is just contrary to the tendency of the corrosion extent after the immersion experiment. Combined with the results of the intrinsic anti-corrosion and pulverization characterization, we can conclude that the weaker corrosion extent of La2MgNi9 in the electrochemical test is attributed to its better intrinsic anti-pulverization capability though the intrinsic anti-corrosion of La2MgNi9 is worse. It has been well accepted that pulverization is induced by the cell volume expansion upon hydrogen absorption [11-12]. Thus, large volume change leads to severe pulverization. Unfortunately, exact measurement of the volume expansion in the present work is difficult due to the multi-phase microstructure. Instead, we summarize the volume changes according to other experimental works where microstructures of these alloys are all sing-phase to ensure the accuracy as far as possible. Based on the data as listed in Table 4, there is no regular trend for the volume changes among the various structures in La-Mg-Ni system. And, no special relationship between the reported volume expansion data and the pulverization performances in the present work can be found. Besides, pulverization is believed to depend on the mechanical properties of the alloys [11-12]. Alloys with the more ductile character are more resistant to pulverization than the brittle materials. Usually, hydrogen storage alloys ar e hard and brittle, thus measuring ductility directly is difficult. Alternatively, Vickers hardness has been used to evaluate the preference of pulverization for the hydrogen storage alloys. And, previous works have found an almost inverse relationship between Vickers hardness and the pulverization rate [11-12, 30], suggesting the availability of Vickers hardness measurement on characterization of the anti-pulverization ability. Fig.17 gives indentations of the various phases in La2MgNi9 and La1.5Mg0.5Ni7 alloy. Evolution of Vickers hardness can be seen in Fig.18. It presents a linear relation between the Vickers hardness and B-side stoichiometry of the structures, which also agrees well with the pulverization behaviors of the alloys. Obviously, the mechanical property is an important factor affecting the anti-pulverization ability in the La-Mg-Ni phases. It is found that hardness differences of the AB3, A2B7 and A5B19 type phase are small. Under low loading of the hardness test, micro-cracks can hardly be observed in all the above three phases. Since the test force increase, micro-cracks can be seen in all these phases, but there is no obvious difference between them. Differently, LaNi5 is the hard phase, but hardness of (La,Mg)Ni2 is far more lower than the other phases. To comprehend more understanding on the crack formation of various phases, a massive sample with a polished surface was partial charged by electrochemical method, and the morphology and distribution of crack was observed. To highlight character of the hard and soft phase, the as-cast La2MgNi9 alloy was selected for the high abundance of LaNi5 and (La,Mg)Ni2. Microstructure characteristics of the as-cast La2MgNi9 alloy are given in the supplementary (Fig.S6-S7). As shown in Fig.19, quite a number of cracks can be observed in the sample which is only charged for 10 min. Most of the cracks exist in LaNi5 with the darkest contrast in the BSE image. One reason is that LaNi5 is the catalytic phase that primarily charged in the La-Mg-Ni system [31-32]. More importantly, it also ascribes to the brittle character of LaNi5 which agrees well with the above result that the hard phase is easy to crack formation. It is noteworthy that cracks are often stopped in front of (La,Mg)Ni2. Obviously, the soft phase is more resistant to crack formation and able to prevent the crack spreading. Similar result has been reported in other literatures where ductile secondary phases are believed to be beneficial to the cycling stability [33]. According to the above results, we can conclude that La4MgNi19 alloy is easy to pulverization as the high abundance of the hard phases LaNi5 and (La,Mg)5Ni19. As to La2MgNi9, little LaNi5 but existence of the soft (La,Mg)Ni2 and (La,Mg)Ni3 make it more resistant to crack emergence. These findings enlighten a way to improve the anti-pulverization ability by introduction appropriate abundance and distribution of soft secondary phases. 4 Conclusions In the present study, corrosion and pulverization behaviors of three typical La-Mg-Ni alloys: La2MgNi9, La1.5Mg0.5Ni7 and La4MgNi19 have been systematically investigated. All the alloys present multi-phase microstructure with (La,Mg)Ni3, (La,Mg)2Ni7and (La,Mg)5Ni19 as the main phase respectively. La1.5Mg0.5Ni7 possesses better electrochemical properties among the three alloys. It is found that pulverization and corrosion with the main product La(OH)3, combined with La2O3, Mg(OH)2 and MgO, have occurred after the electrochemical cycling. The overall corrosion extent of the electrochemical cycled alloys follow the order that La2MgNi9 1.5Mg0.5Ni7 4MgNi19. Immersion test demonstrate that the Mg-rich phases are easy to be corroded in the alkaline solution. The intrinsic anti-corrosion resistance are found to be La2MgNi9 1.5Mg0.5Ni7 4MgNi19, which is inversely proportional to the abundance of the Mg-rich phases. However, the intrinsic anti-pulverization ability just presents an inverse tre nd that La2MgNi9 > La1.5Mg0.5Ni7 > La4MgNi19. It is found that the mechanical property is an important factor affecting the anti-pulverization ability. Vickers hardness elevates with increase of the B-side stoichiometry of the various phases, which agrees well with the pulverization behaviors of the alloys. Furthermore, LaNi5 with the highest hardness is found to be easy to crack formation, but the soft (La,Mg)Ni2 is more resistant to crack formation and able to prevent the crack spreading. The weaker corrosion extent of La2MgNi9 in the electrochemical test is attributed to its better intrinsic anti-pulverization capability though the intrinsic anti-corrosion of La2MgNi9 is worse.
