Health and environmental effects of diesel pollution Essay

Health and environmental effects of diesel pollution - Essay Example Some of these particles are often directly released into the atmosphere while others are formed when they are mixed and react with other pollutants in the atmosphere. These particles often come in various sizes. Fine Particles (PM2.5). These are also known as fine particles and usually measure up to 2.5 microns in diameter. These are seen in almost all sources of fuel combustion, from automobiles, wood burning, industrial plants, and power plants. With their diminutive configurations, they are likely to deeply penetrate the lungs and respiratory system. Where large concentrations of this fine particulate matter are formed, a haze is usually apparent. Coarse Particles (PM10). These are particles which measure about 2.5 to 10 microns and are derived from various sources like natural wind, erosion of soil, or airborne residue from industrial plants. These particles are often visible to the naked eye, and can appear collectively as haze, dust, or soot. Particle pollution always presents a significant risk, however, the risk is usually greater: During calm weather when pollution usually accumulates or builds up In and around factories, especially during busy hours and along near busy roads. When smoke is emitted from wood stoves, fireplaces, forest fires, and other burning vegetation. Health Effects of Particle Pollution & Who is Most at Risk The lungs and the heart are usually affected during particulate pollution. Studies suggest that the initial response to short-term exposure to particle pollution is coughing, along with minor throat irritation. Where larger particles are involved, the lung function is often reduced, along with the rate of respiration and cardiovascular function. Various studies have already been carried out associating fine particles with various health issues, including: Asthma and chronic bronchitis Acute respiratory symptoms, with coughing and chest tightness Decreased lung function, usually felt as shortness of breath Heart attacks Prematur e death among individuals with an existing heart or lung disease These conditions often cause issues with work and school activities. Moreover, the possibility of emergency room visits and admissions is often increased with these conditions. As for longer-term exposures, more health issues often become apparent, life expectancy is often reduced, and other health issues often become exacerbated. The following "sensitive groups" are often vulnerable to health issues with exposure to high levels of particulates: Children, since their lungs are still in the development stage Elderly, especially those already suffering from cardiovascular diseases Those who are asthmatic or who are already suffering from any respiratory problems. In addition, healthy adults who experience respiratory difficulties when exposed to fine particulates may also be affected by the pollution since they are likely to breathe deeply and exert more during exercise or work. Environmental Effects of Particle Pollutio n As was mentioned previously, significant amounts of coarse and fine particles usually create a haze which can affect visibility and compromise visual range to a significant extent. Airborne particles and droplets also usually remain in the air for long periods of time and sometimes even travel great distances. As they settle in a particular place, they may cause damage to surfaces; they can acidify lakes and other bodies of water, and cause significant damage to plants and animals. Nitrogen Dioxide

Energy expenditure, intake and balance Essay Example for Free

Energy expenditure, intake and balance Essay Food is a source of energy intake as it contains carbohydrates; there main function is to store energy in the muscles. Carbs are a macronutrient and come in two different forms, simple which are foods like chocolate and sweets these release energy quickly, the other form is complex which are foods like pasta and rice they release energy slower so are better to keep energy for a sustained period of time. There are certain factors that affect energy intake for instance what gender you are affects how much energy you need, a male’s guideline daily amount is 2500 calories where as a female’s is only 2000 calories. Exercise is a form of energy expenditure; it uses up the energy that has been stored in the muscles and causes the body to lose fluids through sweat. There are also factors that affect energy expenditure such as basal metabolism; this is the amount of energy expended when at rest, the higher the metabolism the more calories you burn meaning that certain people will have to replace more energy than others. Climate is another factor that affects expenditure this is because people in hotter climates lose more energy through sweat than people in cooler climates. (200-300 words) Task 2 [M1] Explain why different nutrients have a differing effect on an individual’s energy intake. Different nutrients have a differing effect on an individual’s intake because each nutrient releases a unique amount of energy and also the speed the energy is released varies for each one. For instance the macronutrient carbohydrates are the body’s main source of energy intake therefore they release the most energy, but even carbohydrates are split in to two groups when determining the speed the energy is released. The two groups are simple carbs and complex carbs, simple carbs are foods like chocolate and sweets their energy release is very quick giving you a short sharp burst of energy but cannot be sustained for a long period of time. On the other hand complex carbs which are found in bread, rice and potatoes release the energy slowly over a longer period of time at a more consistent rate. When talking about other nutrients that release some kind of energy there are only two others, these are fats and protein, fats are like simple carbs releasing only small amounts of energy in quick bursts but their main function for the body is to protect vital organs and provide insulation. Protein is a last resort for energy intake as the energy has to be taken away from the muscles; this is only in rare cases where there are no carbs or fats in the body. (200 words) Task 3 [P4] Describe the following terms: Body Composition: Body Composition is used to describe the percentages of fat, bone and muscle in human bodies. Because muscular tissue takes up less space in our body than fat tissue, our body composition, as well as our weight, determines leanness. Two people of equal height and body weight may look completely different from each other because they have a different body composition. Fat Free Mass: Fat Free Mass is comprised of the components that have no fat in the human body. It can refer to any body tissue that does not contain fat; these include skeletal muscle, bone and water. (50 words) Lean Body Mass: Lean body mass is the mass of the body minus the fat (lipid). Some methods of working this out require specialised equipment such as hydrostatic weighing or DEXA (dual-energy X-ray absorptiometry). Others are very simple such as skin callipers and bioelectrical impedance. (50 words) Task 4 [P4] Describe the following methods of measuring percentage body fat: Skinfold Analysis- This is a method of measuring body fat percentage by taking measurements of fat at 4 different points of the body using a set of skin callipers, they are taking at the bicep, tricep, waist and subscapular (shoulder blade) doing this finds out your fat layer thickness. These measurements are then converted into body fat percentage using an equation; a male should have around 15% body fat whereas a female should have 20-25% due to them having breasts etc. (100 words) Bioelectrical Impedance- Bioelectrical impedance measures the resistance of body tissues to the flow of a small electrical signal. The proportion of body fat can be calculated due to the current flowing through the parts of the body that are made up of mostly of water such as blood, urine and muscle this is not possible through bone, fat and air. By doing this it is possible to work out how much body fat the person has by combining the bioelectric impendence measurement with factors such as gender, age, height, weight, and fitness level. (100 words) Hydro densitometry- Hydro densitometry (which is also known as hydrostatic weighing) is weighing someone while they are in water, it is considered to be the most accurate form of measuring body fat. A very large tank of water is used for this test, firstly a comparison is made between the underwater weight and the dry weight of a person. Due to fat being less dense than the other tissues in the body, it floats more easily. The more fat a person has on their body, the greater the difference between the dry and wet weights. While this method of measuring is very accurate and considered the best way of measuring body fat, not many people use this method because the equipment and test is highly expensive. (100 words) Task 5 [M2] When comparing skin fold callipers and hydrodensitometry both have their advantages and disadvantages for measuring body composition. The cost of callipers is much less than hydrodensitometry, callipers costing around  £15- £20 whereas hydrodensitometry can cost anything up to  £400. The training needed to use the callipers correctly and accurately takes a minimum of 1000 tries but can be performed by anyone; on the other hand hydrodensitometry needs a qualified scientist to use the equipment correctly. Again skin callipers hold the advantage over hydrodensitometry when comparing the speed of measurement. Hydrodensitometry can vary from an hour to three hours due to travel time, changing time, time in pool and time for the results to be calculated. While callipers take only 5 to 10 minutes to get the results. Callipers are much easier to carry out in a field setting as the measurements can be taken anywhere, whereas hydrodensitometry testing has to be done in a specialist room with all the expensive equipment. The one advantage hydrodensitometry holds over skin callipers is the level of accuracy of the results. Callipers results are still very accurate but do not have the same precision of hydrodensitometry results, you also have to take in account human error as this could affect them and this isn’t possible in hydrodensitometry as computers conclude the results. (250 words) Task 6 [D1] How can knowledge of an athlete’s energy intake and expenditure and monitoring of their body composition be used by a coach/support team to aid an individual’s development with respect to sports performance? Knowledge of an athlete’s energy intake and expenditure and monitoring of their body composition can be used in many ways by a coach to aid an individual’s sport performance. If a coach knows exactly what body fat percentage his athlete has he can determine whether he thinks that is a suitable level for the sport his athlete participates in. For example if a coach of a sumo wrestler sees his athlete has low body fat percentage he can put him on a high calorie diet to give him a better chance of matching his opponent, on the other hand if a coach of a marathon runner sees his athlete has a higher body fat percentage that he’s competitors he can put him on a specialised diet and make him do more intense workouts. Looking at a player’s energy intake can also help out the coach in trying to improve his athlete; he can work out whether his athlete is getting enough energy in his diet and whether it has a suitable energy release time. For instance a sprinter may be eating complex carbs like bread and pasta before a race which wouldn’t be suitable as they release energy slowly, the coach can see this and change it to some simple carbs like chocolate as they release energy In a quick short burst which is much more suitable for a 10 second race. Finally a coach can take into consideration whether his athlete is expending his energy suitably, for example if a football player is going on a 5 mile run before a match the coach can suggest that he reduces the distance as he is wasting energy which he should be saving. Expending too much energy in training can also lead to the risk of injury and fatigue so the coach can keep his training at a suitable level for the athlete he is training. Fruit and veg should take up around 33% of your diet; they contain the micronutrient vitamins and minerals, the role of vitamins is to help maintain a healthy immune system to fight off illness and infection, whereas minerals are needed for body functions such as hair growth and to keep bones strong. Starchy foods such as bread, rice and potatoes should also take up around 33% of your diet; they contain the macronutrient carbohydrates which are required to store energy in the muscles for physical activity. Milk and dairy foods such as cream and cheese should take up around 15% of your diet and contain the mineral calcium which is key for maintaining strong bones and teeth. Non-dairy sources of protein such as meats and fish should make up around 15% of your diet these are rich in protein which is needed for the growth and repair of muscles. Red meats such as beef and lamb also provide the body with iron which helps prevent anaemia. Fats and sugars such as chocolate and sweets should only take up 8% of your diet as consuming to many can lead to health problems. They do however provide the body with insulation and an alternate energy source to carbohydrates.

The Authors :: essays research papers

The Authors   Ã‚  Ã‚  Ã‚  Ã‚  In the world of writing, the writer’s lifestyle, imagination, background, or world views is what will make the piece attractive. The three writers’ T.S. Eliot, Ernest Hemingway, and F. Scott Fitzgerald wrote most of their pieces with the way they viewed the world or things that had occurred in their lives. The following paragraphs will tell you about the writers past to induce them into writing what they did. T.S. Eliot, a very cerebral poet and also wrote essays. Eliot grew up in a fine family, his father was a business man and his mother was very involved in the community and wrote poetry. Eliot went on to going into Harvard where he earned his PhD in philosophy. After attending Harvard, he traveled around Germany on a travel scholarship and later attended Oxford University where he only stayed a year. His early works reflected the disillusionment of the postwar generation and the tragedy of contemporary civilization. In 1928 Eliot considered himself an Anglo-Catholic, which reflected in his poetry a more positive turn. Eliot received the Nobel Prize in 1948. Eliot’s poetic themes concentrate on the condition of the world and only gain an optimistic strain later as a result of his conversion to Christianity. His new-found worldview colors his later works into optimism rather than despair, though he recognizes that the world is still a dark place in which to live. His poems â€Å"The Love Song of J. Alfred Prufrock† and â€Å"Death by Water† from the poem â€Å"The Waste Land† are two manifestations of his early social disillusionment while â€Å"The Hollow Men† and â€Å"Journey of the Magi† are written later with the more hopeful backdrop of Christianity. Ernest Miller Hemingway was born in 1899 in Oak Park, Illinois, in an orthodox higher middle class family as the second of six children. His mother, Mrs. Grace Hale Hemingway, an ex-opera singer, was an authoritarian woman who had reduced his father, Mr. Clarence Edmunds Hemingway, a physician, to the level of a hen-pecked husband. Hemingway had a rather unhappy childhood on account of his 'mother's, bullying relations with his father'. He grew up under the influence of his father who encouraged him to develop outdoor interests such as swimming, fishing and hunting. His early boyhood was spent in the northern woods of Michigan among the native Indians, where he learned the primitive aspects of life such as fear, pain, danger and death.

The Treatment of Women in Bram Stokers Dracula Essay -- Dracula E

The Treatment of Women in Bram Stoker's Dracula  Ã‚   In reading Bram Stoker's Dracula, I find the treatment of the two main female characters-- Lucy Westenra and Mina Harker-- especially intriguing. These two women are two opposite archetypes created by a society of threatened men trying to protect themselves. Lucy is the Medusa archetype. She is physically attractive, and wins the heart of any man who comes near her (e.g. Arthur, Quincey, Jack, and Van Helsing). Her chief quality is sensual beauty, but her sexual desire is repressed and not allowed to communicate. And yet both the spiritual side and the sexual side are in her, and when the long repressed sexuality finds a vent, it explodes and takes over completely. In other words, she is transformed into the completely voluptuous female vampire precisely because her sexual side of personality had been completely buried by her Victorian education. Her repressed self needs such expression that when Dracula came along, she went out to greet him, and then invited him into the house (by opening her window to the bat). He is her vent for sexual expression. When Lucy becomes a vampire herself, John Seward describes her as follows: She seemed like a nightmare of Lucy as she lay there; the pointed teeth, the bloodstained, voluptuous mouth -- which made one shudder to see -- the whole carnal and unspiritual appearance, seeming like a devilish mockery of Lucy's sweet purity (252; ch.16). And for this voluptuous Lucy he has no pity: "the remnant of my love passed into hate and loathing; had she then to be killed, I could have done it with savage delight" (249; ch.16). But why this attitude? I believe it is the aggressive sexuality that the vampire Lucy displays that ... ...in excluding her from their undertakings, and include her again. However, now that she is infected with vampire blood and is capable of reading Dracula's mind, the men both fear and need her. They are forced to accept her in the public realm, but the quest is to eventually rid her of evil influence and restore her purity again, that is, to turn her back into the virtuous woman who will stay in the dominion of the home and not pose a threat to men. The end of this novel is the restoration of a world as the Victorians know it: the vampire destroyed, the women rid of their evil sexual desires and kept out of the dangerous world outside their homes, and the men safe and free in a male-dominated world, playing their exclusive gallant, intelligent, and adventurous roles.    Text Cited Stoker, Bram.

Marketing Across Culture Success or Dilemma Essay

Marketing across culture is one of the biggest issues which multinational companies have been confronting nowadays. Since marketing is an important factor for the propagation of a particular product or company, marketing plan should also be effective simultaneously. Every organization has to pay attention towards all the aspects which can make a marketing plan successful and ethical aspect is one of them. Since global marketing is a complex process, ethical issues like cultural diversity is one of the major reasons that can cause failure of marketing plan. Marketing across culture is basically defined as product or service promulgation beyond the borders. Since beyond borders, culture, lifestyle and audience get changed, the attitude of the people also gets changed simultaneously. (Hutterer 2006) So, it can be regarded an ethical dilemma to market the products on international level and for dealing with such situation, company needs to scrutinize interests, traditions and culture of the indigenous people. However, different organizations have developed dissimilar strategies in order to cope with such ethical issues. Reasons of this dilemma Cultural diversity is generated by dissimilarity between native culture and the culture beyond the borders. Since every society has its own culture, its audience also possesses dissimilar concerns, ideologies, concepts, principles and keeping all these dynamics under consideration, a marketing plan is developed so that it can come up with the requirements of that respective culture. (Hall & Hall, 1990) If the organizations neglect this aspect without considering the emotions and affiliations of its audience important, the result appears in the form of negative consequences. Since the main reason of this dilemma is dynamic nature of traditions, the organizations usually employ strategic plan keeping the regional aspects under consideration. However, in such cases, the organizations which assume theory of relativism are considered successful because it enables them to come up with regional cultural requirements. Since there are no absolute criteria for universal morality in this regard, this ethical dilemma has been solved using the utilitarian approach and the example can be taken from IKEA Inc. In Saudi Arabia, they have kept ethical and moral concerns in limelight while marketing their services and their apology for using female images in marketing transmedia can be taken as evidence in this regard. (Quinn 2012) Another reason why this thing is considered a dilemma is that marketing across culture makes it complex for the organizations to comply with the needs of customers since not only traditions, culture and thoughts of the audience change with the boundaries, but their taste and priorities also change simultaneously. For instance, McDonalds in India markets its products keeping the vegetarian audience under consideration while in other regions like USA, UK and Canada, they market their products through promulgating other additional factors. Hence, through this way, McDonalds not only keeps the cultural but also religious needs of its audience under consideration and this ethical aspect of its marketing plan makes it outstanding in one way or other. However, with the expansion of the business on global level and with the advancement in technology, marketing has become rather a technical yet interesting task and the reason behind this fact is the propagation of social media and similar other sources. These sources have made it ample easy to approach targeted audience yet the cross-culture issue is still persistent since these sources do not give any remarkable evidence regarding the cultural diversity and marketing plan. Comparatively, there are different other organizations like Air Asia which have been struggling with the ethical issue of marketing across culture. Though it has assumed different ethical approaches like absolutism, egoism etc in order to deal with its audience yet there is no remarkable progress in making its service a world popular one. However, there can be several strategic options available to deal with this issue of marketing across culture. Proposed solution: Different solutions for dealing with the issue of marketing across culture are as followed: Pluralism: The first solution in this regard can be given in the form of pluralism since it enables the organization to have an in-between path of utilitarianism and absolutism. (Hinman 2011) Some organizations use absolute ethics for marketing its products and some consider utilitarianism as the best source of marketing across culture but both of them might cause failure since no absolute policy or theory works when the regions are diverse and discriminate from each other. So, only an organization, who assumes theory of pluralism in order to deal with this global dilemma, can get successful position in global market. For this purpose, the organization can also do cultural analysis before marketing its product. Cultural analysis before marketing: This solution can be regarded one of the most significant steps in order to deal with the dilemma of marketing across culture. The reason behind this claim is that understanding the culture of the native people would not harm their feelings in any way. Suppose, if McDonalds never does cultural analysis in India and launches its products without differentiating vegetarian and non-vegetarian food, the result would appear in the form of violation of ethical code of that country. In such case, this organization would face severe opposition and there would be no profitability as well. So, another best solution to deal with this issue would be cultural analysis of the organization and before marketing a specific product or service in any region of the world, it is mandatory for it to analyze the potential market from cultural perspective. Change management strategy: Apart from assuming above given both solutions, the organization would also need to have caliber to adopt change management strategy since marketing across culture would need a severe change in the core marketing plan of the company. In such case, the company would have to deal with the internal issues as well and it can deal with this global ethical dilemma only if it would be able to deal with the internal issues of the organization. Through assuming all these three solutions, all the organizations aiming at expanding its services beyond borders can deal with the ethical dilemma of marketing across culture. Hence, only through dealing with ethical issues, the organizations can get successful marketing promotions throughout then world. References: Hall, E. T. & Hall, M.

Financial Ratio Analysis on Philip Morris.

Financial Ratio Analysis on Philip Morris. The price customers are willing to pay for a product depends, in part, on the availability of substitutes. The absence of close substitutes in the case of cigarettes means that consumers are comparatively insensitive to price increases. This makes demand for tobacco inelastic with respect to price. The buyer's propensity to substitute cigarettes for another product is largely dependent on their price- performance characteristics. The needs being filled by cigarettes are very complex.Cigarette companies measure average per cigarette yields of nicotine by following standardized machine testing methods. These machine methods were never intended to reflect what and how smokers actually inhale. The method proves that no tests can precisely duplicate conditions of actual human smoking and, within fairly wide limits, no one method can be said to be either 'right' or 'wrong'Philip Morris USA (PMUSA) frequently describes cigarette brands using terms such as "full flavor, medium, mild, light, and ultra light."CIGARETTESmokers have varying preferences; PM USA offers products with differing yields of nicotine, as measured by machine methods. They believe that it is appropriate to contribute to differentiate their brands on this basis that descriptors such as lights, ultra lights, medium, and mild, help communicate these differences to adult smokers.The tobacco industry has many strong competitors with varied portions of market share. As of now, the price leader is Philip Morris. When they increase prices, other brands will follow the lead to avoid price wars. Any attempt to take away market share from the leader will result in more harm than good for the lower companies with fewer shares. Philip Morris is the industry leader and is able to heavily promote and advertise a new product. Marlboro is one of the most well-known brands in the world.

The High Renaissance, Bramante essays

The High Renaissance, Bramante essays The heroic vision of the High Renaissance artists and their patrons is shared, even aroused, by their wealthy patrons who set out to better the ancients. In Rome and Milan artists and architects are commissioned to aggrandize the triumphs of popes and princes, dynasties and The Church. Bramante led in his field to the realization of a powerful new scope for knowledge, representation and building. Science virtuosity, classicism, expressiveness and Neoplatonism are all celebrated in their work. Examine in this contention in the work of Bramante and show how it advances modernism. Bramantes architectural designs from the High Renaissance were crucial in the development and expression of Modernism in building designs. Over the preceding three hundred years before the High renaissance, there was a reemergence of Humanist philosophies. Starting with the teachings of St Francis of Assisi (1182-1226) there began a renewed interest human dignity inspired by Christian virtue. Developing from this in the Early Renaissance, through economic prosperity of city-states in northern modern day Italy, especially, and the rediscovery of classical Roman ideals through writing, art and architecture Humanism became a popular scholarly secular pursuit. Christianity and Humanism were studied to complement one another resulting in a type of Neoplatonism. By the time of the High Renaissance the expression of Humanistic and Christian ideals are clearly displayed in many Artists work of the time and in fact go beyond the original intents of Humanism and Christianity to develop a ph ilosophy and style that is unique to the Renaissance. This essay will explore how Bramante expressed these new ideas and how they were crucial in the development of Modernism. Born in Urbino, Bramante (1444-1514) initially studied as a painter. On moving to Milan in 1481 and working court with Leonardo he moved from painting and began designing buildings. Whi...
