Free Essays on Sex and Aids in Canada

As of 2001, close to 40 million people are living with HIV/Aids and close to 3 million died from it. By 2004, Aids will be the leading cause of death on the planet. (UNAIDS 2002). These are startling figures that no doubt impress upon any global policy maker to try to do more to help find a cure. In the meantime, the media has helped to ensure that the vast majority of global citizens are educated on and aware of the threat posed by this merciless virus. It is estimated by UNAIDS that close to 55 000 Canadians are presently infected with HIV. The disease that was once labeled the â€Å"gay man’s disease† no longer discriminates, everyone person who chooses to become sexually active risks exposure. Although reported HIV cases have ceased to increase in recent years across our country, certain social groups in our communities instead have witnessed a steady elevation within their populations. This essay will attempt to prove that societal marginalization and discrimination against aboriginals, drug injection users and gays have contributed to the steady rise of HIV infection rates and diminished the effectiveness of health promotion initiatives within these groups. The economic and social power imbalance between Aboriginals and Non-Aboriginals in Canada plagues reserve and off-reserve communities with a host of social problems. Aboriginals represent a higher percentage of Canada’s inmate population which places them in a more high risk scenario for exposure to HIV. Once released, they may return home and unknowingly infect other members of their community. In 1996, 9% of all new HIV infections in Canada were among Aboriginals which is an alarming statistic considering they only represent 2.8% of our country’s total population. Allard 2 Health Canada also reported that 60% of all aboriginal male reported cases was amongst men who have sex with men. Injection drug use accounts for 54% of accounted aids cases among Abo...

Tear Gas - What to Do If You Are Exposed

Tear Gas - What to Do If You Are Exposed Tear gas (e.g., CS, CR, Mace, pepper spray) is used to control riots, disperse crowds, and subdue individuals. It is intended to cause pain, so exposure to it is not fun. However, the effects of the gas usually are temporary. You can expect relief from most of the symptoms within a couple of hours of exposure. This is a look at how to prepare for a potential encounter with tear gas, with tips on how to respond. Symptoms of Tear Gas Exposure stinging and burning of the eyes, nose, mouth, and skinexcessive tearingblurred visionrunny nosesalivation (drooling)exposed tissue may develop a rash and a chemical burncoughing and difficulty breathing, including a feeling of chokingdisorientation and confusion, which may lead to panicintense anger The disorientation and confusion may not be totally psychological. In some cases, the solvent used to prepare the tear gas may contribute to the reaction and may be more toxic than the lachrymatory agent. What to Do Tear gas usually is delivered in the form of a grenade, which is fitted onto the end of a gas gun and fired with a blank shotgun cartridge. Therefore, you may hear shots being fired when tear gas is used. Dont assume you are being shot at. Do not panic. Look up when you hear the shot and avoid being in the path of the grenade. Tear gas grenades often explode in the air, delivering a metal container which will spew gas. This container will be hot, so do not touch it. Do not pick up an unexploded tear gas canister, since it could explode and cause injury. The best defense against tear gas is a gas mask, but if you dont have a mask there are still steps you can take to minimize damage from tear gas. If you think you might encounter tear gas you can soak a bandana or paper towel in lemon juice or cider vinegar and store it in a plastic baggie. You can breathe through the acidified cloth for several minutes, which should give you sufficient time to get upwind or reach higher ground. Goggles are a great thing to have. You can use tight-fitting swim goggles if chemical safety goggles arent available. Dont wear contacts anywhere you might encounter tear gas. If you are wearing contact lenses, immediately remove them. Your contacts are a loss as is anything else you cant wash. You can wear your clothes again after you wash them  but wash them separately that first time. If you dont have goggles or any sort of mask, you can breathe the air inside your shirt, since there is less air circulation and therefore a lower concentration of the gas, but that is counterproductive once the fabric becomes saturated. First Aid First aid for eyes is to flush them with sterile saline or water until the stinging starts to abate. Exposed skin should be washed with soap and water. Breathing difficulties are treated by administering oxygen and in some cases using medication that are used to treat asthma. Medicated bandages can be used on burns.

Overview of the conflicts Essay Example | Topics and Well Written Essays - 500 words

Overview of the conflicts - Essay Example s necessary to have a clear understanding of both of their arguments and the possible solutions they put forward, to recognize the actual reason of the conflict. Chua begins her essay by explaining how Aunt Leona, her father’s twin sister who was murdered by her driver in Philippines and how no action was taken by the Philippines police because her aunt was Chinese. This was nothing shocking for the people as hundreds of Chinese in Philippines were kidnapped every year and brutally murdered by the Ethnic Filipinos. . The minority Chinese dominated the whole of industry and commerce in the country whereas all menial jobs were done by the Filipinos. Chua cites this example to show how the market-dominated minority of Chinese are despised and taken revenge by the majority of Filipinos and how the government supports it. For Chua, the conflict lies in the relationship among three factors- markets, democracy and ethnic hatred. She believes that Americans today are perceived as the world’s market- dominant minority and this has obviously resulted in the September 11 World Trade Center episode. According to her, the global spread of m arkets and democracy is the major reason for group hatred and ethnic violence throughout the Non- Western world. This results in three kinds of violence: a) violence against markets that target the market dominant minorities’ wealth, b) attack against democracy by forces favorable to the market dominant minority, and c) violence directed against the market dominant minority itself .Thus she considers the working of market dominant minority against the wishes of the impoverished majority as the major factor behind the conflict and possible changes in the prevalent system can bring about a difference. Huntington, on the other hand, believes that the fundamental source of conflict is not primarily ideological or economic but cultural. Clashes occur when people divide themselves based on their common cultural identity such as language,

In order for learning to take place, one must have a source from which to draw upon knowledge. Once this is achieved, recollection is attained. Thus, knowledge has a purpose and a direction which can be analyzed through various means. This is the nature of knowledge. [150 words] Part II. Method/Hermeneutics. Seventh-Day Adventist4 theology is unique. Seventh-Day Adventists’ theology approximates a movement with apocalyptic overtones. Adventists’ hermeneutics, or interpretational theory, stems from the books of Daniel and Revelation, which are both books of the Bible that deal with prophecy. Seventh Day Adventists are particularly concerned with prophecy and how it relates to the interpretation of the sacred text of the Bible. Basically, the main ideas that characterize Seventh-Day Adventism has been carefully analyzed. The way the Bible is interpreted by people within the religious culture of Seventh-Day Adventism is very specific. The theme of the end times reoccurs often, more often than not, in the hermeneutics of the Seventh-Day Adventists. The main hermeneutic regarding the book of Daniel deals mainly with the foreshadowing of the coming of Christ. The main hermeneutic regarding the book of Revelation deals mainly with the symbols associa ted with end times and the impending return of Christ. [150 words] Part III. Method/Hermeneutics. The Seventh-Day Adventist hermeneutic is continued to be discussed in this section. The interpretational theory of the Seventh-Day Adventists depends largely on the text being evaluated or analyzed. In the case of Seventh-Day Adventists, the text that is mainly focused upon—usually, but not always—is Revelation. This is because a large part of Seventh-Day Adventist theology usually focuses upon the up-and-coming return of Christ to earth in order to

Water first Essay Example for Free

Water first Essay The film captures the inspiring story of Charles Banda, a man who has dedicated his life to providing clean and safe water to the people of Malawi. It was this dedication that saw him turn down a political office offer from none other than the country’s president. If you were to ask anyone in Africa what a political appointment means in that side of the world then you would understand the depth of his commitment to provide water to the impoverished citizens of Malawi, a poor sub-Saharan nation of 12 million people with serious water deficiency. However, back to the film, and something one gets from the film is how grave the consequences of not having water are. The film avoids going in to those morbid details that have sometimes characterized films coming out of Africa and other third world countries. The film captures the green countryside showing a large water reservoir then moves on to show girls moving in a brownish environment (a symptom of dryness) carrying heavy loads in their heads- presumably water. Another scene shows a girl drawing water from a shallow well. The water she is drawing cannot be particularly termed as clean by any standards. It may not even qualify to wash utensils in a lower class neighborhood in Harlem. There are many other scenes of interest, but in the overall, the director does present a picture of the situation as it is in a majority of the African nations and other developing countries without taking away too much of their dignity. In addition, the film also presents some crucial numbers such as the number of people lacking clean water. Relationship between water and the millennium development goals (MDGs) The millennium development goals were arrived at in 2000 by a United Nations declaration and it is envisioned that its targets are to be reached by 2015. There are 8 goals in total, and watching the film, I have a clear picture of the central role to be played by water in the attainment of each of the eight goals. There are two women in the film who give us the common diseases in their communities and among them; cholera and dysentery emerge as some of the most common. You will hardly hear of these diseases in the developed world, and even when they happen they do not come in catastrophic proportions. They are mostly isolated. Yet, for African countries such as Malawi, cholera epidemics are not uncommon. Of importance however, is how the girl child is affected by lack of water. Goal three of the millennium development goals is to promote gender equality and empower women. This goal cannot be achieved if the girls are going to continue carrying the heavy loads for long distances as we saw in the film. Unfortunately, most of the countries that are yet to achieve the MDGs are mostly composed of patriarchal societies. These societies hardly value the place of the woman and for that reason; the women are treated as second class citizens. They are mostly confined to lowly duties such as fetching water, cooking, washing utensils and taking care of small children. Men, on the other hand, get to do more valuable jobs, most of which concern taking care of property. In fact, in such societies, women do not own property-they are properties themselves. Most of the roles listed for women will need water to perform and it is therefore incumbent upon them to ensure that they have enough water supplies. Given that scenario, we can then expect that water shortages will hardly affect men because they have no urgent need for it. As we have seen from the film, it is the girl child who is always out in the wild going to fetch water and one wonders whether she has the same chance of doing well in school in comparison with the boys. Long term empowerment of women cannot be achieved if the girls do not have equal access to education like their male counterparts. Of course, much more than the mere provision of water has to be done, but it has to be the starting point. After providing the water, civic education may then be done to get the society to appreciate the role education will play in the life of the girl child. An equally important area covered by the film is goal number two. This is the area of achieving universal primary education. By this declaration, it is hoped that by the year 2015, primary education will be a universal right for every child. For the girl child however, the right to education must go beyond the promulgation of such a policy. They have more specialized needs in terms of sanitation and without water then their school attendance cannot be guaranteed especially during menstruation periods. That means that their rights to education cannot be guaranteed because of water. Has the United Nations been successful? So far, the UN has been involved in a number of initiatives aimed at easing the strain on the available water resources. It has even predicted that future wars will be fought over water resources as opposed to the current wars, most of which are based on territorial disputes. The issue of water shortage cannot be addressed wholly; it requires addressing the underlying issues that cause it. The range of factors may include global warming, desertification and rapid industrialization. Although the UN does not explicitly list water as a basic human right, it does include access to food as a basic human right. It is hard for food to exist without water and it can therefore be assumed that the UN considers water a basic human rights. It cannot however be said that the organization has been successful at addressing the issue of water accessibility in most of the developing countries. The film gives a figure of 1 billion people as being unable to access water because of their inability to afford it yet most governments are busy privatizing the provision of water. An important lesson from the film is that water provision should have a social approach. The waterman in the film has been largely successful in his efforts because his social approach has enabled him to mobilize substantial resources for use in the sinking of wells. The developing countries are clearly not prepared to commercialize the provision of water because a substantial part of its population still does not have access to it. To that end, the UN needs to do more to dissuade these countries from commercializing the provision of such a basic commodity. Would I recommend the film? The situation in Malawi is representative of how the general situation is in most of the developing countries and especially those in Africa. I would recommend the film to anyone interested in getting a feel of what the average person in a country without water is going through. Those of us in the developed countries take too many things for granted. Many cannot fathom life without the running water or electricity. Many of those in the developed world get to learn about the problems facing other citizens of the world from national geographic channels or Hollywood movies such as blood diamonds. Although they are made in Africa or whichever continent, their objectives are mainly commercial and may not therefore, have the patience or motivation to develop a wholesome picture of the situation. The film attempts to give a balanced view of the situation without having to apportion blame, either to the government or the communities. It simply calls our attention to the problems existing in these countries and leaves the rest to our own judgments. I therefore propose the film to anyone intent on understanding the development needs in these countries. Works Cited UNDP.

Music Copyright Essay -- Copyright Laws Music Industry Essays

What is a Copyright? Music Copyright is a very important aspect of the music industry. The Copyright law was established to preserve the creativity and rights of authors, composers, performers of expression. Copyright is the law that protects the property rights of the creator of an original work in a fixed tangible medium. (http://dictionary.reference.com/browse/copyright) A fixed tangible medium is something substantial like copying lyrics on paper or putting a song on tape or CD. Copyright can be seen every where in the music industry. Many music artist of our culture today have been involved in copyright issues. Recently, on MTV news it was stated that, "As the music industry becomes increasingly concerned about protecting the integrity of artists copyrights in the age of MP3. Prince has now filed a motion in New York federal court aimed at shutting down several websites offering free downloads of the Artist's songs." (http://www.mtv.com†¦19990304/prince.jhtml) In addition, in recent music news, "Nine Inch Nails lead man Trent Reznor copyright infringement suit was dismissed. Another artist claimed that the Reznor had stolen material for his last album." (http://www.mtv.com†¦19991202/nine_inch_nails.jhtml) The copyright law has become an important legal aspect to know our music generation. What works can be copyrighted? Copyright applies to more than musical works. It protects many different things. It protects musical works, literary works, dramatically works, dance works (choreography), sculptures, graphic works (maps, graphs, etc.), pictorial works, motion pictures (videotapes), sound recordings, and even computer creations (computer programs, databases). (http://askjeeves.com/copyright/html) Although there are a lot categories that can be protected by copyright, not every expression can be protected. These original expressions are not eligible for copyright protection. Ideas and discoveries are not eligible for copyright protection. A speech or music performance that is not recorded, written (in a fixed medium) is not protected. Titles are also not eligible for copyright protection. For example, if artist A writes a song titled "That Thing" and then artist B writes a totally different song, but titles the song "That Thing" also. Artist B has not infringed on the copyright law. How can an artist copyright their work? Copyright prot... ...ts new and old artist from having their original forms of expression stolen. A performing artist or songwriter should have a good understanding of the factors of the copyright law. An artist always wants to protect their work so the wrong people can not abuse it. By having a deep knowledge about the copyright law, the artists can save themselves from paying endless unnecessary legal fees. . Work Cited Baskerville, David.

Social Theory

Midterm ExamQ1: My dorm roommate Angelica is a psychology major and she disagrees with my major on Sociology. Angelica insists that psychology is the real deal for studying people and that sociology is completely clueless subject. I disagree with her on that since I was looking into the different examples of sociology applied to human behavior. I looked into the class textbook, â€Å"Introducing Social Theory† in the first section was individualistic theory. Individualism means an individual's personal attributes. I started seeing how sociology could describe people based on their personalities reflecting on their actions towards social interactions with others (Jones, Bradbury, and Le Boutillier, 1). I also showed Angelica an example on people having a controlling persona was an example of individualism based on individuals own ways of behavior. I told her, â€Å"Not everything is explained in psychology. Sociology gets more into a society realm perspective.† Q3: Garfinkel was a colleague of Goffman. He was a believer of symbolic interactionism, and wanted to study close proximity behavior amongst people. He wanted to teach students how to use different tactics in order to learn more about the ordinary social atmosphere. In â€Å"Introducing Social Theory,† Ethnomethodology was based on the methods people do based on getting a reaction and using that reaction to embark that the action from the person is a true fact. Garfinkel's breaching experiment brought into gender interaction based on conversations. For instance, there is a radio station that picks on the second caller for a trivial questionnaire. The caller answers all of the questions correctly and gets a free trip to Disneyland for a weekend getaway; the caller is enthusiastic. The host asks the caller's name and the response is: Devon. The host gets an idea based on Devon's tone of voice and believes that Devon is a young woman since her tone of voice is medium pitched. Ethnomethodology also goes for the experiment on race. For example, I remember watching a YouTube video on a teenage boy that was questioned constantly about what his racial identity was. He said that people cannot understand that he is mixed race. When it comes to ethnomethodology, the aspect of race is an idea that people are assumed the things associated with identity is the real traits of someone based on their culture. Q5: W.E.B. Du Bois and C. Wright Mills are sociologists that bring in the study of people and the struggles that they face. Du Bois focuses his theory on ethnic struggles amongst African Americans and their impressions amongst living with Caucasians in â€Å"Spiritual Strivings†. His main theory involves looking at the social spectrum of society in general and a realm of the treatment of African Americans (Du Bois, 2). C. Wright Mills' â€Å"The Sociological Imagination† goes into depth about people facing personal problems and feeling very down about being stuck in a difficult circumstance and feeling internal conflict (Mills, 3). Goffman was a symbolic interactionist that believed in the fact that people would act in front of a stage and back stage in order to give off an impression from performing from a script. In his own book, â€Å"The Presentation of Self,† Goffman goes into how an individual will go into feeling like making the first impression is difficult based on making a perfect impression once group interaction takes place (Goffman, 12). This also applies with going into social roles in order to understand what the interactions are and the types of conversation taking place. Du Bois would analyze Goffman by underlining the fact that based on Caucasians are racist amongst African Americans simply for being different and the ideas of what race is that it is nothing but a mere idea of African Americans treated as outcasts. Goffman makes a point about the actor that can make up a believable statement to others while being on stage. He says, â€Å"A cynical individual may delude his audience for what he considers to be their own good, or for the good of the community, etc.† (Goffman, 18). Goffman makes the statement that an actor can cover up a default while performing in order to make a lasting impression. C. Wright Mills makes a demonstration at looking at the biography of an individual to analyze an inflicted social problem. Q7: My social problem that I chose is the high cost of living in the Bay Area. For Weber, this problem is analyzed based on social class dividing people. In â€Å"Class, Status and Social Stratification,† Weber's point of view on class has to deal with people in a group that share the same struggles and the same views of acquire basic necessities (Weber, 1). Weber would approach this problem looking at which class could easily pay for the rental costs and analyze that only middle-income people would be moderately struggling while the upper class would have no trouble for paying rent. There would be another approach when it comes to earning money and the actions that people do in order to pay the rent on time. Another approach Weber would do is analyzing the high rental costs based on capitalism. Since the rental costs are going up, people ask their bosses for a raise in order to keep their jobs without relocating or quit. Capitalism was once seen as a religious duty to preserve money and wealth was subject to be cautious. While wealth was taken seriously, living in poverty was not an excuse because of being a sign of struggle (â€Å"The Spirit of Capitalism and The Iron Cage†, 4). Capitalism amongst the Bay Area is all about paying the rent on time and making everyone work overtime in order to stay in their residential area. Durkheim would take on a different approach where he would make a positivism tactic. He would claim that the rental costs are not the problem, but it is the people that are able to survive without cracking under pressure. Durkheim goes into the fact that there are people that need strategic discipline in order to pay their rent, overlooking the high cost and more on the functions of people (â€Å"Suicide†, 3). Durkheim would be mainly about social order and categorizing the statistics of financial restraint versus bankruptcy. These two different approaches contradict Weber and Durkheim on the social problem for high cost rent in the Bay Area. ReferencesDu Bois, W.E.B. 1903. Pp. 1-12 in The Souls of Black Folk.

Emission Control

Emission Control Techniques 1. INTRODUCTION The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons, carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits as to the amount of each of these pollutants that could be emitted from an automobile. The manufacturers answer was the addition of certain pollution control devices and the creation of a self-adjusting engine. 1981 saw the first of these self-adjusting engines. They were called feedback fuel control systems. An oxygen sensor was installed in the exhaust system and would measure the fuel content of the exhaust stream. It then would send a signal to a microprocessor, which would analyze the reading and operate a fuel mixture or air mixture device to create the proper air/fuel ratio. As computer systems progressed, they were able to adjust ignition spark timing as well as operate the other emission controls that were installed on the vehicle. The computer is also capable of monitoring and diagnosing itself. If a fault is seen, the computer will alert the vehicle operator by illuminating a malfunction indicator lamp. The computer will at the same time record the fault in it's memory, so that a technician can at a later date retrieve that fault in the form of a code which will help them determine the proper repair. Some of the more popular emission control devices installed on the automobile are: EGR valve, Catalytic Converter, Air Pump, PCV Valve, Charcol Canitiser etc. Like SI engine CI engines are also major source of emission. Several experiments and technologies are developed and a lot of experiments are going on to reduce emission from CI engine. The main constituents causing diesel emission are smoke, soot, oxides of nitrogen, hydrocarbons, carbon monoxides etc. Unlike SI engine, emission produced by carbon monoxide and hydrocarbon in CI engine is small. Inorder to give better engine performance the emission must be reduce to a great extend. The emission can be reduced by using smoke suppressant additives, using particulate traps, SCR (Selective Catalytic Reduction) etc. 2. EMISSION CONTROL IN SI ENGINE 2. 1. Methods to reduce emission in SI engine. 2. 1. 1. Catalytic Converter Automotive emissions are controlled in three ways, one is to promote more complete combustion so that there are less by products. The second is to reintroduce excessive hydrocarbons back into the engine for combustion and the third is to provide an additional area for oxidation or combustion to occur. This additional area is called a catalytic converter. The catalytic converter looks like a muffler. It is located in the exhaust system ahead of the muffler. Inside the converter are pellets or a honeycomb made of platinum or palladium. The platinum or palladiums are used as a catalyst (a catalyst is a substance used to speed up a chemical process). As hydrocarbons or carbon monoxide in the exhaust are passed over the catalyst, it is chemically oxidized or converted to carbon dioxide and water. As the converter works to clean the exhaust, it develops heat. The dirtier the exhaust, the harder the converter works and the more heat that is developed. In some cases the converter can be seen to glow from excessive heat. If the converter works this hard to clean a dirty exhaust it will destroy itself. Also leaded fuel will put a coating on the platinum or palladium and render the converter ineffective. 2. 1. 2. PCV Valve The purpose of the positive crankcase ventilation (PCV) system, is to take the vapors produced in the crankcase during the normal combustion process, and redirecting them into the air/fuel intake system to be burned during combustion. These vapors dilute the air/fuel mixture, they have to be carefully controlled and metered so as not to affect the performance of the engine. This is the job of the positive crankcase ventilation (PCV) valve. At idle, when the air/fuel mixture is very critical, just a little of the vapors are allowed in to the intake system. At high speed when the mixture is less critical and the pressures in the engine are greater, more of the vapors are allowed in to the intake system. When the valve or the system is clogged, vapors will back up into the air filter housing or at worst, the excess pressure will push past seals and create engine oil leaks. If the wrong valve is used or the system has air leaks, the engine will idle rough, or at worst engine oil will be sucked out of the engine. 2. 1. 3. EGR Valve The purpose of the exhaust gas recirculation valve (EGR) valve is to meter a small amount of exhaust gas into the intake system; this dilutes the air/fuel mixture so as to lower the combustion chamber temperature. Excessive combustion chamber temperature creates oxides of nitrogen, which is a major pollutant. While the EGR valve is the most effective method of controlling oxides of nitrogen, in it's very design it adversely affects engine performance. The engine was not designed to run on exhaust gas. For this reason the amount of exhaust entering the intake system has to be carefully monitored and controlled. This is accomplished through a series of electrical and vacuum switches and the vehicle computer. Since EGR action reduces performance by diluting the air /fuel mixture, the system does not allow EGR action when the engine is cold or when the engine needs full power. [pic] Fig. 2. 4. EGR Valve 2. 1. 4. Evaporative Controls Gasoline evaporates quite easily. In the past these evaporative emissions were vented into the atmosphere. 0% of all HC emissions from the automobile are from the gas tank. In 1970 legislation was passed, prohibiting venting of gas tank fumes into the atmosphere. An evaporative control system was developed to eliminate this source of pollution. The function of the fuel evaporative control system is to trap and store evaporative emissions from the gas tank and carburetor. A charcoal canister is used to trap the fuel vapors. The fuel vapors adhere to the charcoal, until the engine is started, and engine vacuum can be used to draw the vapors into the engine, so that they can be burned along with the fuel/air mixture. This system requires the use of a sealed gas tank filler cap. This cap is so important to the operation of the system, that a test of the cap is now being integrated into many state emission inspection programs. Pre-1970 cars released fuel vapors into the atmosphere through the use of a vented gas cap. Today with the use of sealed caps, redesigned gas tanks are used. The tank has to have the space for the vapors to collect so that they can then be vented to the charcoal canister. A purge valve is used to control the vapor flow into the engine. The purge valve is operated by engine vacuum. One common problem with this system is that the purge valve goes bad and engine vacuum draws fuel directly into the intake system. This enriches the fuel mixture and will foul the spark plugs. Most charcoal canisters have a filter that should be replaced periodically. This system should be checked when fuel mileage drops. 2. 1. 5. Air Injection Since no internal combustion engine is 100% efficient, there will always be some unburned fuel in the exhaust. This increases hydrocarbon emissions. To eliminate this source of emissions an air injection system was created. Combustion requires fuel, oxygen and heat. Without any one of the three combustion cannot occur. Inside the exhaust manifold there is sufficient heat to support combustion, if we introduce some oxygen than any unburned fuel will ignite. This combustion will not produce any power, but it will reduce excessive hydrocarbon emissions. Unlike in the combustion chamber, this combustion is uncontrolled, so if the fuel content of the exhaust is excessive, explosions that sound like popping will occur. There are times when under normal conditions, such as deceleration, when the fuel content is excessive. Under these conditions we would want to shut off the air injection system. This is accomplished through the use of a diverter valve, which instead of shutting the air pump off diverts the air away from the exhaust manifold. Since all of this is done after the combustion process is complete, this is one emission control that has no effect on engine performance. The only maintenance that is required is a careful inspection of the air pump drive belt. 2. 2. Modification in SI engine to reduce emission. †¢ Multi-port fuel injection system to completely replace carburetors. †¢ Electronic engine management to accurately regulate fuel supply to cylinders by sensing various engine parameters. 4-valve system to replace 2-valve system, improved combustion chamber design and improved inlet manifold design for axial stratification of charge. †¢ Turbo-charged (TC) and Turbo-charged After Cooled (TCAC) engines. †¢ Turbo-compounded engines; they are found to be upto 18 per cent better than the conventional engines. †¢ After treatment, catalytic co nverter and exhaust gas recycling. Some future directions for engines are: †¢ Lean burn technology, air-fuel ratio as lean as 22:1 is possible with 4-valves, high swirl and squish generated turbulence. †¢ Use of ceramic components (e. g. low density Silicon Nitride, Si3N4) such as piston pins, valves, blades in turbochargers. †¢ Variable Valve Activation (VVA) providing improved charge control of SI engines, reducing fuel consumption by 5 per cent at low/medium speed and  13  Ã‚   per cent at full engine speed. †¢ 3. EMISSION CONTROL IN CI ENGINE 3. 1. Methods to reduce emission in CI engine 3. 1. 1 Particulate filter. Particulate filters are highly effective in the elimination of particulate matter (PM10) or soot from diesel exhaust. It has a variety of filter coatings and designs, depending of the engine application and duty cycle. . 1. 2. Selective catalytic reduction Selective Catalytic Reduction of NOx (generally abbreviated with SCR deNOx) is a very pow erful technology to reduce the NOx emission and fuel consumption of truck and passenger car diesel engines. The European truck manufacturers starting in October 2005, when EURO-4 emissions legislation enters into force, will introduce SCR deNOx on a large scale. With SCR deNOx a 32. 5% aqueous urea solution is injected upstream of the catalyst. Urea which converts to NH3 (ammonia) in the hot exhaust gases reacts with NOx to form harmless N2 and H2O. The urea quantity needs to be precisely dosed as a function of the engine NOx output and the catalyst operating conditions. 3. 1. 3. Smoke Suppressant additives There are a number of additives, which are added in order to reduce the smoke from CI engine. HYDRAX ATH (hydrated alumina), HYDRAMAX (magnesium hydroxides and hydroxy-carbonates), CHARMAX LS (low smoke), CHARMAX LS ZST & LS ZHS (zinc stannates & zinc hydroxystannates), CHARMAX AOM & MO (ammonium octamolybdate & molybdic oxide), CHARMAX ZB200 & ZB400 (zinc, magnesium, and calcium borates) etc. This reduces the amount of smoke produced by various chemical reactions. The smoke produced can also be controlled by deairating, maintenance, catalytic mufflers, fumigation etc. 3. 1. 4. Control of odour It is very difficult to estimate the odour produced by the diesel engine because the lack of standard tests has not allowed much work to be done in this direction. Catalytic odour control system muffler and or catalyst container are under development and it has been found that certain oxidation catalysts if used under favorable conditions reduce odour intensity. But the tests are still going on. 3. 1. 5. Exhaust Gas and After treatment Modeling While the diesel (compression ignition) engine is more efficient than the conventional spark ignition engine from a thermodynamics standpoint, it has the potential for a large negative environmental impact. The lean combustion of these devices provides the perfect environment for the production of NOx; relatively high temperatures and abundant oxygen. In addition, direct injection of fuel into the combustion chamber creates rich fuel pockets that can cause the formation of particulate matter (soot). Recently these emissions have come under increased scrutiny from the Environmental Protection Agency (EPA). Their radical nature (smog) in the atmosphere and subsequent health hazards has caused the EPA to act to increase the regulation standards for both 2007 and 2010. Unlike the three-way catalysts currently used on spark-ignition based platforms, diesel after treatment systems will not utilize one device for all problematic emissions. Instead, devices are targeted to take care of only one or a few issues at a time. For instance, Diesel Particulate Filters (DPF) might take care of the particulate matter while a Diesel Oxidation Catalyst (DOC) will eliminate the CO and HC and a Lean NOx Trap is used for the NOx emissions. Until now, diesel engine manufacturers have been able to meet the legislation though in-cylinder technology. The proposed EPA legislation has caused the diesel industry to work on finding cost-efficient after treatment technology while still looking in-cylinder for improvements. 3. 2. Modification in CI engine to reduce emission 3. 2. 1. Commercial vehicle emission control Several improvements are needed. These could be achieved through redesigning of engines and application of new technologies:  · Improvement in fuel injection system and use of higher injection pressure. . . Common rail system unit injections instead of multi-cylinder fuel injection pumps.  · Electronically controlled injection system to provide variable injection timing with good dynamic response to engine load, speed, and temperature.  · Improved cylinder head design, inlet port, re-entrant combustion chambers.  · 4-Valve system to improve volumetric efficiency and provide better mixing of fuel and air. Turbo-charged and Turbo-charged aftercooled engines to provide higher specific power, better fuel economy, and less emission pollution.  · After-treatment, particulate traps, and catalytic converters. 3. 2. 2. Passenger Car Diesel Engine In India, Indirect Injection (IDI) diesel engines are commonly used in passenger cars. Due to the pricing policies of fuels, the running c ost of diesel cars is lower than those of petrol cars. Diesel engines are popular for taxis, most of which are retrofitted by diesel engines. Private cars with OE diesel engines are also in demand. Major directions for engine development to control different pollutants are as follows:  · HC emission control requires, – low sac volume nozzles; – Complete combustion of injected fuel; – minimum lube consumption.  · NOx emission control is helped by, – cooling of intake air before entering the engine; – Retarded combustion; and – Moderate air motion.  · Particulate emission control is helped by, – high injection pressure; – fine fuel atomization; – intensive air motion; – high excess air; and – minimum lube consumption. 4. EMISSION CONTROL NORMS IN SI AND CI ENGINE The first Indian emission regulations were idle emission limits which became effective in 1989. These idle emission regulations were soon replaced by mass emission limits for both gasoline (1991) and diesel (1992) vehicles, which were gradually tightened during the 1990’s. Since the year 2000, India started adopting European emission and fuel regulations for four-wheeled light-duty and for heavy-duty vehicles. Indian own emission regulations still apply to two- and three-wheeled vehicles. 4. 1. Emission control norms in SI engine.

The implementation schedule of EU emission standards in India is summarized in Table 4. 3 The above standards apply to all new 4-wheel vehicles sold and registered in the respective regions. In addition, the National Auto Fuel Policy introduces certain emission requirements for interstate buses with routes originating or terminating in Delhi or the other 10 cities. For 2-and 3-wheelers, Bharat Stage II (Euro 2) is be applicable from April 1, 2005 and Stage III (Euro 3) standards would come in force preferably from April 1, 2008, but not later than April 1, 2010.

In India, the demand for oil for the transport sector is estimated to increase over the next decade. This sector is the largest consumer of petroleum products . Government is providing policy support, fiscal incentives and regulatory measures for development of alternative energy vehicles and fuels. Battery operated vehicles, fuel cell vehicles, hydrogen powered vehicles and bio-fuel powered vehicles have been identified in this context. The development activities of such fuels and vehicles need to be further encouraged particularly in view of their potential to protect the environment. Hybrid Electric Vehicles (HEVs) use the combination of engine of a conventional vehicle with electric motor powered by traction batteries and/or fuel cell. This combination helps in achieving both the energy and environmental goals. The deployment of a large number of this type of vehicles would help us in terms of environmental benefits, reduction of oil consumption and reduction in emissions. In hybrid electric vehicles propulsion, energy is available from more than one source of energy. The three configurations of HEV are series hybrid system, parallel hybrid system and split hybrid system. Fuel cells produce electricity, employing reaction between hydrogen and oxygen gases, electrochemically. Fuel cells are efficient, environmentally benign, compact, modular and reliable for power generation. Different type of Fuel cells currently under development are the Protons Exchange Membrane Fuel Cells (PEMFCs), Phosphoric Acid Fuel Cells (PAFCs), Molten Carbonate Fuel Cells (MCFCs),Solid Oxide Fuel Cells (SOFCs) etc. Hydrogen is receiving worldwide attention as a clean fuel and efficient energy storage medium for automobiles. Hydrogen can replace or supplement oil used in road transportation. Bio-fuel is an efficient, environment friendly, 100 per cent natural energy alternative to petroleum fuels9-10. In view of the potential of being produced from several agricultural sources and because of its low emission characteristics, bio-fuels in recent years are receiving a great deal of attention as a substitute to petroleum fuels. Ethanol and bio-diesel are the two bio-fuels which are being looked upon as the potential fuels for surface transportation.

Human Resource Management Essays - Human Resource Management

Human Resource Management Essays - Human Resource Management Human Resource Management Name Institution Date Introduction The companies whose human resource departments will be focused on in this case are the Coca Cola Company and Southwest Airlines. Human resource management is an essential part of an organization. The development of this is the first step, the ground on which the future of thecompany depends. The human resource department plays a critical role on promoting, training, hiring and recruiting individuals fitting the two company's strategies . The human resource managers have the duty of hiring individuals who fit with organizational culture and who display the cultural characteristics that the organization wants to advance. Human resource managers serve as the single managerial voice in determining and setting the kind of culture in the organization. Human resource also has a sole responsibility of hiring those individuals who fit with the organizational culture and implementation of the same culture (Grant, 2010). Organizing Human Resource At Coca-Cola Company The management at coca-cola company focuses on the acquisition and retention of highly skilled and knowledgeable employees so that it can maintain its top position in the market. It treats these resources as an asset. It provides such conditions of employment and procedures that enables all employees to develop a sense of unity with the enterprise and to carry out their duties in the most willingand effective manner. It also provide s for security of employment to workers so that they may not be distracted by the uncertainties of their future. These objectives, strategies, policies and programs are specified by the company, which guides the management and unions in taking decisions (Doba, 1999) . Job Analysis and Designing Job analysis is the procedure for determining the duties and skills requirements of a job and a kind of person who should be hire for it. Job analysis consists of two products. One is job description and the other is job specification. Job description refers to a list of job duties, responsibilities, reporting relationship, working conditions and supervisory responsibilities. It can also be a list of a job's human requirement, which is requisites education skills, personality and so on . Coca-cola human resource depart ment checks its own job description and job analysis in which they get the information about employees work activities, human behavior, performance standards, job context and human requirement and also other information for recruiting, selection, compensation, performances appraisal, training and employees relationship (Grant, 2010) . Planning and Forecasting Planning constitutes t he process of deciding what position the firm will have to fill and how to fill them. Coca -cola HR department involves in company strategic planning they are involve in sufficient planning in hiring new employees in the future. They forecast for the expected employees need in the organization. Theyforecast of employees on change technology and increasing in productivity. After planning they send thus report in the head office for approval if they get approval they start recruitment process (Fitz-enz Davison, 2002) . Employees Happiness Employees are the most important asset for every company so it is very important to give them appreciations. The satisfaction of the employees makes the company successful. Employees Trip [Turkey] Employees are motivated through taking them for trips. This makes them encouraged and they will keep working in one good heart, for their own sake and company's sake. They will thereby work the best of their abilities and capabilities. Human resource department says that employees are their assets, they are careful about employees health and benefits. They give following compensation and benefits; basic salary, bonuses, medical facil ity pick and trip gravity fund and social security (Fit z-enz Davison, 2002) . Southwest Airline Labour Cost The low fare carrier advantage is in much more flexible work rule that allow s cross-utiliza tion of virtually all employees. S uch cross-utilization and a long standing culture of co-operation among labor groups translate into lower unit labor cost. Carriers like S outhwest, ha s a tremendous o cost advantage over others simply because they generate more output per employee. Employees and Labor Relations Southwest ha s been highly regarded for its innovative management style. It maintains a relentless focus on a high performancerelationship and its peoples management practices have been

Appropriate Consequences for Student Misbehavior

Appropriate Consequences for Student Misbehavior Students will misbehave in class. As teachers, we might not be able to stop all forms of misbehavior before they start. However, we have complete control over our own reactions to student behavioral issues. Therefore, we must choose our responses wisely, making sure that they are appropriate and logical. The old adage, the punishment must fit the crime, is especially true in a classroom setting. If you choose something illogical, students will learn less than if your response directly relates to the situation, or they might miss out on important information being taught in class that day. Following are a series of situations that have been chosen to illustrate appropriate responses in your classroom to help establish behavior management. Note that these are not the only appropriate responses, but instead chosen to show the difference between appropriate and inappropriate consequences. A student uses a cell phone for non-academic purposes. Appropriate: Tell the student to put the phone away.Inappropriate: Confiscate the cell phone.Explanation: A cell phone policy should be clearly stated in the student handbook and reviewed with students whenever there is an infraction. Teachers should record repeat offenders in order to share that the student is distracted in class with parents. Rules should be designed to meet the needs of students while addressing educators’ concerns. Some districts allow teachers a choice to make the decision by clearly posting if students can use their devices. Information on the webiste  Common Sense Media can help teachers plan for device use that considers digital citizenship and student safety. Regardless, digital devices like cell phones should only be used in class when there are specific goals in mind, critical thinking, collaboration, advancement, and equity. A student is late to class. Appropriate - The student misses the daily starter or do-now activity and could lose any points associated with this activity.Inappropriate - The teacher ignores the situation, and the student has no consequences for their tardiness.Explanation - Tardiness is a big deal, especially if left unchecked. Teachers should have a tardy policy in place to deal with problem tardies. Having a daily do now or warm up is one way to give students an immediate benefit for being to class on time. One note of caution, a student who is frequently tardy could build up a large number of zeros for not completing the warm-up activity. In this case, the warm-up activity could be used for extra credit points. There is a differemce between grading for ability and grading for behavior. A student does not bring in his or her homework. Appropriate - Depending on the school policy, the student could lose points off their homework assignment. The student could also receive a lower rating in academic behavior.Inappropriate - A lack of homework results in the student failing the class.Explanation -Homework is done outside of the control of the classroom. For this reason, many schools are deciding not to penalize missing homework. If teachers grade only in-class or summative assessments, then the grade accurately reflects what students know. However, keeping track of homework for completion can be valuable information to share with parents. National Education Association (NEA) suggests that all stakeholders (teachers, parents, and students) work together in any effort to set homework policies. A page on the NEA website states: Policies should address the purposes of homework; amount and frequency; school and teacher responsibilities; student responsibilities; and, the role of parents or others who assist students with homework. A student does not have materials (pen, calulator) needed for class. Appropriate - The teacher provides the student with a pen or pencil in exchange for collateral. For example, the teacher might hold on to one of the students shoes to ensure that the pen or pencil is returned at the end of the class.Inappropriate - The student does not have materials and cannot participate.Explanation - Students who can not finish any classwork without materials. Extrae quipment (calculators) orsupplies should be available in class. A student does not have their book in class. Appropriate - The student does not have a textbook during the lesson for the day.Inappropriate - The teacher gives the student a textbook to use without comment.Explanation - If textbooks are required in your day-to-day classroom, it is important for students to remember their texts. It is a rare situation where you have more than a couple of extra textbooks in your class. If students accidentally take an extra text with them, you will have most likely have lost that text forever. A student does not raise their hand but calls out answers instead. Appropriate - The teacher does not respond to the student who calls out and does not call on them.Inappropriate - The teacher allows individuals to answer without having to raise their hands.Explanation - Requiring students to raise their hands is an important part of wait time and effective questioning techniques. If you do not continuously uphold this rule, then students will no longer raise their hands in class. A student uses a curse word in class. Appropriate - The teacher reprimands the student saying, Do not use that language.Inappropriate - The teacher ignores the curse word.Explanation - Profanity should have no place in the classroom. If you ignore it, students will take note and will continue to use it in class. Note: Realize that if the profanity was used against someone else in the class, a form of bullying or harrassment, the consequences should be greater than if a curse word just slips out. Record the event.

Humanities Essay Example | Topics and Well Written Essays - 500 words - 8

Humanities - Essay Example nd noting their increasing wealth, decided to tax the military widows.(Fant 1982) Initially the women accepted this even though it was an obvious case of taxation without representation. However, by 195 B.C. this emergency was over and unlike the provinces, Rome refused to repeal this Oppian Law. Nevertheless, after a demonstration by thousands of affected women supported by sympathetic tribunes they did repeal it. Later in 42 B.C. again an attempt was made to impose similar taxation.(Letkowitz 1982)However, this time it was to pay for a civil war against a rebellious faction. Hortensia was the first female to speak at a Tribunal in the Forum, and was able to successfully argue that women should not be required to pay taxes to support killing of their husbands and fathers. and thereby significantly reduce the pool of women subject to the tax. Aside from Hortensia, the Sabine women must be considered as icons of Ancient Rome (historylink102.com). In fact legend indicates that but for them the Roman Empire may not have ensued. Initially mainly men settled in this rough city, so Romulus devised a plan to attract women to grow Rome’s population. He invited a nearby tribe, the Sabines to a festival inside the city, where the men were attacked and many killed and the women abducted and raped. The surviving Sabine men later returned to Rome under King Titus to retrieve their women, but they were happy with their new lives in Rome and negotiated a truce with the Sabines and Romans uniting and sharing power in Rome for years to follow. The Forum demonstrations illustrate how women even without legal powers were able to use their newly acquired economic leverage craved by the state to pressure it to enact policies more favorable to their interests. On an individual level, wives of high ranking officials, including the emperor, could also exert some influence, although sometimes as in the case of Agrippina, this could be for purely selfish, evil personal motives.

Battles of history, Strategist Thinking, Agree or not Essay

Battles of history, Strategist Thinking, Agree or not - Essay Example One of Britain’s immediate aims was to prevent the French navy from being captured by the German. This gave rise to Operation Catapult on July 3, 1940. A British naval force based in Gibraltar went to Mers-el-Kebir, Algeria, to assist the remaining French navy that had fled. The French crews were offered a choice to sail to Britain at once, to join them in the battle against Germany, where the British would offer them the necessary supplies.2 This way, it would give them (the French) a chance to move their ships somewhere secure or scamper their fleet. All the choices were turned down by the French, hence the British had no alternative but to fire and destroy the French, thus killing over 1,200 of them. Thus, Sun Tzu advocated for creation of an illusion of choices while indirectly directing your opponent to your most preferred option where you lay in ambush.3 Anthony Adamthwaite, The Making of the Second World War (New York: Routledge, 1992), 30. Kenneth Brody, The Avoidable War: Pierre Laval and the Politics of Reality, 1935–1936 (New Brunswick, NJ: Transaction Publishers, 1999), 20. Donald Busky, Communism in History and Theory: Asia, Africa, and the Americas (Westport, CT: Praeger Publishers, 2002), 23. Another crucial battle faced by the British was the channel battle. During this operation, Sea lion was the German code name for its strategy in taking over the United Kingdom. This begun with a series of bomb attacks against British ships in the English Channel, in early July 1940, and the first attack was on July 10. This was despite Hitler making a speech on July 19 advocating for peace with Britain, which was a tactic to buy time. British ships in the Channel incurred heavy damage, but they were able to conserve pilots and planes since there was an oncoming battle. This strategy can be seen in Sun Tzu as art of deception which involves concealing your intentions while calculating your surprise attack. A good general never commits his whole arsenal in battle. Then, Hitler began large bombing raids on air bases and military command posts in southern England early in August 1940. This strategy was aimed at breaking Britain’s will. On August 13, nicknamed â€Å"Eagle Day† by the Germans, Germany deployed over 1,400 bombers and fighters across the English Channel. This whole effort only yielded a damage of thirteen British fighters while losing more than three times the number of theirs. The Germans tried to employ the tactic of ‘Attack at full force to completely destroy and demoralize your enemy†, but apparently, the British were ahead of them as they employed the tactic of ‘let your enemies exhaust their strength.’ Hitler directed the Luftwaffe to attack major British cities like London in early September 1940. The attacks which started on September 7 went on into May the following year. During this Second World War, there was a constant bombing of the United Kingdom by Germany, po pularly known as the â€Å"Blitz,† which took place Between 7 September 1940 and 16 May 1941. Major attacks which involved more than 100 tonnes of explosives were dropped targeting 16 British cities: the capital, London, being attacked 71 times. Others like Birmingham, Liverpool and Plymouth were attacked 8 times, Bristol 6, Glasgow 5, Southampton 4 and Portsmouth 3. There were also large raids targeting other smaller cities eight in number. Luftwaffe bombed London for 57 nights in a row. Over one million houses in London were destroyed
