Environmental lapse rate Essay Example

Environmental lapse rate Essay Example Environmental lapse rate Paper Environmental lapse rate Paper The temperature measured at the ground is 15. Assuming that the air parcel moves adiabatically through the atmosphere, what will be its temperature at each pressure level up to and including 500 hap? Assume ground level is equivalent to 1000 hap) (4 marks). Height (hap)Temperature 500 -35 600 -25 700 -15 800 -5 900 5 1000 15 If the parcel is then forced down to a height of 3000 m, what will its temperature be? (2 marks). If a parcel is then forced down a height of mm, its temperature will be -1 ICC as mm is papa. This is due to the fact that the atmospheric pressure at mm is papa. Temperature decreases along the DALE because the air parcel expands. This is due to fact that pressure decreases within the atmosphere. Re-calculate parts (1) and (2) but this time assume that air parcel is saturated (6 marks). Height (hap) Temperature 500 -15 600 -9 700 -3 800 3 900 9 If the saturated air parcel is now forced down a height of mm, its imperative will be -ICC as mm is equal to papa Environmental Stability Exercise C (Total 10 marks) The following temperature soundings are obtained: Height (hap) Tenderheartednesss air parcel (Co/mm/papa) Unsaturated air parcel (001000m/ 1 Poppa) 1000 34 34 34 800 12 22 14 700 2164 600 -2 10 -6 500 -12 4-16 300 -25 -8 -36 -30 -14 -46 The stability of the atmosphere with the saturated air mass is unstable as the air mass is warmer than the environment. However if the parcel of air were to be saturated from ground level, it would rise in the atmosphere and decrease in temperature at the SAL R. But this parcel of air would carry on ascending in the atmosphere, making it stable. The unsaturated air mass is conditionally unstable, as it will rise to about at papa/mm the parcel of air becomes saturated as it has become cooler than the environmental temperature surrounding it. It will then continue to decreasing in temperature at the saturated adiabatic lapse rate (SAL R) of around ICC / mm, as it descends making it unstable Dew points, relative humidity and cloud formation Exercise D (Total = 22 marks) Plot a graph of mixing ratio vs.. Temperature and use this to help answer the questions in this section (6 marks). The graph may be plotted either in Excel or on regular graph paper. See attached If the temperature and the dew point of a parcel of air at the ground are DDCD and DDCD respectively what will the height of condensation be? (6 marks). Height of Condensation 125 (Ta-Tad) = 125 (23-13) = 125 x 10 Height of Condensation= mm Calculate the relative humidity of this parcel of air at the ground (8 marks). What happens if the dew point and temperature at the ground are equal? (2 marks). Relative Humidity (RE)= (Actual Vapor Density) (Saturation Vapor Density) x 100 ICC = 28. 1 numb ICC = 14. Numb = 14. 979 28. 104 = 0. 53298 0. 53298X100= 53. 289% marks). If the dew point and the ground level temperature were to be equal the surrounding air parcel would be saturated (completely), as the relative humidity would be at its maximum. Exercise E (Total = 12 marks) Explain clearly the nature and possible behavior of an air parcel rising from the ground, with a dew point of 1 co and the following environmental temperature profile. See table Height (m) Temperature0cTemperature of air parcel (Co) Dew point Co 28 28 10 1000 15 188 2000 9-2 6 3000 -3 -8 2 -10 4-8 15 -14 -14 Assuming that the air parcel and the environmental temperature at ground level are equal. The air parcel rises adiabatically losing ICC per mm and the dew point decreases by ICC every mm. The air parcel remains unsaturated or dry at mm and then after mm it becomes saturated. Therefore the height of condensation lies within the altitudes of mm-mm. This can be calculated relatively easy using this equation: Height of condensation 125 (Ta Tad) Inputting my figures = 125 (28- 10) = 125 x 18 = mm After saturation of the air parcel, the temperature of the air parcel will crease at the saturated adiabatic lapse rate (SALE), which is around 6001000m. When the temperature of the air parcel is warmer than the environmental temperature as it is from mm mm the atmosphere is unstable. When the parcel reaches mm, it becomes stable because the air parcel is colder than the environmental temperature, in that case the air parcel stops rising. Therefore the atmosphere is conditionally unstable. Exercise F (Total = 14 marks) A mass of air with a ground temperature of ICC and a dew point of -ICC is forced to ascend a 3000 m mountain. If the environmental temperature at 000 m is Describe the changes in air mass and dew point temperatures you might expect to observe. (8 marks). I have drawn a diagram of the changes in air mass and dew point temperatures you might expect to observe below When air is forced down a mountain, it is an example of forced convection. The air mass and dew point values change as the air mass rises and falls. According to thermodynamics, as air rises, it looses heat energy, as pressure is lost because of the air mass expanding in size. The temperature decreases by 10 and the dew point temperature decreases by ICC. At the top of the mountain, the air parcel saturates at mm. The air parcel is cooler than the environmental temperature, which means that the air parcel will begin to fall down the slope at the Dry Adiabatic Lapse Rate (DALE). At each altitude the air parcel temperature decreases by 1 co and the dew point rises by ICC. As pressure is being increased when the air parcel is decreasing temperature increases. There has been a 1 net increase in air mass temperature from 1 ICC to ICC; same with the dew point temperature as there has been a ICC decrease from -ICC. We can calculate height of condensation takes place at with this simple equation 125X22 -mm Therefore we can at about the altitude of mm clouds start forming as the air parcel starts becoming saturated. Calculate the relative humidity of the air masses before and after ascent. (4 marks). Relative Humidity = Virtue XIII% Mart Before ascent Air temperature= 18 Mixing ratio-? egg/Keg 2. 8 Relative humidity O After descent Mixing ratio= egg/keg Mixing ratio-? 2. G/keg Relative humidity= 100 18 . 46% . Before ascent the humidity of the air mass was 21. 5% and after descent the humidity of the air mass was 18. 46% 3. How would the behavior of the air mass change (if at all) if the mountain as only 2000 m high and the environmental temperature at that height was -7 co? (2 marks) If the mountain were only mm, the temperature of the dew point would decrease by -ICC as we have seen beforehand and so would become saturated. With the environmental temperature at -7 Co the air parcel would be warmer than that of the surroundings and consequently the air parcel will carry on growing and expanding in size, dropping in pressure and losing heat at the saturated adiabatic lapse rate. Deprograms and stability Exercise G (Total = 18 marks) Values of the environmental air temperature are obtained at each of the eights given below. The dew point temperature (Tad) at the surface is 1 ICC. Plot a deprogram to show the trajectory of an air parcel or air mass rising from the surface. Explain, by reference to the deprogram how the parcel would behave and, hence, describe the stability of the atmosphere. Annotate the deprogram to indicate clearly the presence of any condensation levels or changes in air parcel/mass behavior. See diphtheria attached Height (hap) Height (m) Dew point (Co) Temperature (Co) 1000 010 15 900 1000 88 800 2000 23 700 3000 -4 -8 600 4000 -10 -6 500 5000 -16 -15 The dew point rises adiabatically losing heat. At mm or papa saturation of the air parcel occurs as the dew point and the air parcel are at the same temperatures. To calculate the height Of condensation we can use this simple equation Height of condensation = 125 (Ta Tad) = 125(15-10) -mm On my Deprogram attached, I have shown a dew point (red line) which come together with the dry adiabatic line (green line). This illustrates the fact that when the saturated air parcel stopped ascending. When the air is saturated the air parcel stops ascending. The dew point will continue to cool down at he saturated adiabatic lapse rate of around ICC per mm. From this I illustrated the saturated adiabatic line (SALE) (black line). The Environmental Lapse Rate (LEER) is shown in green on the deprogram, and lies to the right of the SALE. This means that the atmosphere is stable, which means thats the air parcel will continue to rise. Exercise H (Total = 100 marks). You should be aiming to write about 500 words As you will have seen during these exercises, air behaves in a certain way when it is forced to rise over a topographic barrier. Describe one example of such a topographically induced airflow from somewhere in the oral, indicating clearly how geography and atmospheric conditions influence the creation and behavior of the wind. Illustrate your discussion with diagrams as appropriate, and make sure that you provide clear references for the information you give (note that Wisped is not an acceptable source Of information). The meaning of a topographic barrier is an obstruction within the land e. G. Mountain ranges that change wind and rainfall pattern within the mountainous area. An example of such a topographically induced airflow is the Serbia Nevada mountain range. The Sierra Nevada is located in the west f the United States running along the east of California. It extends north about implies from the Mojave Desert to the Northern Californian Cascade Range. The Sierra Nevada varies in width and is about miles wide at Lake Tahoe and miles wide towards the south of the mountain range. Its remarkable skyline and extraordinary landscapes makes it one of North Americas premiere views. Biologically, it is the home to the worlds most ancient trees, the sequoia. In previous history, the focus Of the gold rush and now is the home to 3 national parks, 20 special wilderness areas and 2 cantonal monuments. Topographic barriers such as mountains and hills force normal winds within the area up and over their slopes which are about 4421 m high at the highest peak. As an air parcel rises, it cools as the higher it goes within the atmosphere, the more pressure is lost and therefore heat is lost as there is energy being transferred in order for the air parcel to expand. Cooler air is capable of holding less water vapor than warmer air. As the air parcel cools it reaches its maximum saturation point, this water vapor is forced to condense, depositing rain or snow on windward slopes. When air is met by a mountain, it is elevated up and over the mountain, cooling as it rises. If the air cools to its saturation point, the water vapor condenses and a cloud forms. When these air parcels form large enough droplets; precipitation will form. Westerly Wind coming in from the Pacific Ocean carrying water vapor is trapped by the Sierra Nevada and is forced up an uphill slope where Otherwise the air would have passed unscathed. This air is then forced back down causing a phenomenon called the Sierra Nevada wind rotors. These wind rotors are periodic changes of atmospheric pressure, temperature and altitude in a current of air caused by vertical displacement e. G. A topographical barrier such as the Sierra Nevada. The result of these wind rotors is as mild as strong winds or windstorms. The strength of the wind rotor is dependent upon wind speed coming in, ground temperature, wind patterns and water vapor. With that said, the formations of these wind rotors are unpredictable. As air up a mountain is cooler due to the environmental lapse rate (air cools around 6. ICC every mm an air parcel rises up. This creates a distinct monochromatic around the mountain range. The lower zone of the mountain angel is dry and cooler whereas the top has cold and severe conditions. This is indicated by the flora existing in these parts. The positioning of uphill slopes in relation to the sun has an influence on the climate. South-facing slopes are sunnier and support entirely different ecological communities than north-facing slopes. The south side of a mountain may experience spring conditions weeks or even months ahead of its north side. Where year-round snow or glaciers exist, they are supported by the shade provided by north- and west-facing slopes.

Analysis of the Human Rights Act, 1998

Analysis of the Human Rights Act, 1998 Human Rights Law ‘Despite the Human Rights Act 1998, the courts have failed appropriately to limit the scope for the exercise of breach of the peace powers.’ The Human Rights Act 1998 received royal assent on November 9, 1998 and came into force on October 2, 2000. The objective of said Act was to harmonize the domestic law of the United Kingdom with the European Convention on Human Rights. To reaffirm the commitment of the UK to human rights and civil liberties, it is now possible under the said Act to file a claim for violation of the ECHR without going to the European Court of Human Rights in Strasbourg. Says Weinstein: This ability to transcend national law, and to compel revision of such law to comport with rights guaranteed by the European Convention in a broad range of areas, most often within the exclusive purview of national and local courts, is of historic note. Generally, nation states have been the final arbiters of most issues affecting their citizenry and within their borders. By treaty, the signatory nations of Europe have granted the ECHR binding authority to decide cases affecting their citizenry and other persons subject to their authority. In instances where state law is found inconsistent with an ECHR judgment, the nation at issue is obliged to amend its national law to comport with the ECHR decision. These cases illustrate the concept of what is increasingly being referred to as an evolving European supranational identity. The ECHR grants jurisdiction to any individual, non-governmental organization, or group claiming be a victim of a violation of the European Convention by a ECHR signatory nation, and to bring cases before it, as does, in applicable cases, the European Court of Justice (the â€Å"ECJ†), the court of the European Union, based in Luxembourg. Equally important, it prohibits any public body from behaving in a manner that is incompatible with any of the rights guaranteed under the ECHR. The Human Rights Act has gone a long way in limiting arbitrary actions from public bodies, in particular, police officers. It cannot be denied, however, that the laws on â€Å"breach of the peace† grant have historically been so vast in scope that in some occasions, human rights violations arise. The definition of â€Å"breach of the peace† (also known as breach of the Queen’s peace) has been discussed in the Court of Appeal decision of Howell, where it was stated as follows: We are emboldened to say that there is a breach of the peace whenever harm is actually done or is likely to be done to a person or in his presence his property or a person is in fear of being so harmed through an assault, an affray, a riot, unlawful assembly or other disturbance. It used to be that the prospect of violence alone would not be enough to be considered a â€Å"breach of the peace†, as in the comment of Farqhuarson LJ that â€Å"The act which puts someone in fear of violence taking place entitles a police officer†¦to detain the actor but it is not a breach of the peace, for the violence has not yet occurred.† There has been scant support for this view, such that in the present time, â€Å"breach of the peace† also embraces â€Å"behaviour likely to cause a violent reaction†, even if such behaviour is not of itself violent.

Article Critique Research Paper Example | Topics and Well Written Essays - 1000 words

Article Critique - Research Paper Example The article clearly discusses the results of recent experiences with the use of therapeutic hypothermia after cardiac arrest in a patient. The layout of the article itself flows well and offers a clear and distinct linear progression. The four doctors who participated in the research, Sagalyn, Band, Gaieski, and Abella are from the Department of Emergency Medicine and Center for Resuscitation Science at the University of Pennsylvania. Their departmental positions indicate a high degree of knowledge in this field, and make them uniquely qualified to write this particular article; with qualifications such as these it would be easy to believe that they have the necessary skills to make this type of analysis on the subject. The abstract offers a clear overview of the study itself, detailing what their objectives were, the setting in which their review took place, the subjects used as a part of the study, the measurements that were taken, and the main results of the outcome of the analysi s itself. Each specific section offers a concise summary for that heading, and, again, flows well and in a linear fashion. The phenomenon of using therapeutic hypothermia after a patient experiences cardiac arrest is clearly identified and the question addressed by the paper is thoroughly discussed, complete with ample research into the matter. The question presented was whether or not therapeutic hypothermia was beneficial after a patient experiences cardiac arrest, with the results showing â€Å"increased survivial with an odds ratio of 2.5 and favorable outcome with 2.5† (Sagalyn, Band, Gaieski & Abella, 2009). The specific purpose of the article is easy to identify, determining whether or not therapeutic, clinically induced hypothermia is beneficial to the patient after they have experienced a heart attack, and the conclusion of this research is likewise concisely stated; â€Å"the survival and neurological outcomes benefit from therapeutic hypothermia are robust when co mpared over a wide range of studies of actual implementation† (Sagalyn, Band, Gaieski & Abella, 2009). The literature review was done in order to gain the initial data to be able to start the research project itself, and as such, added information on the topic itself, as it provided the burden of proof for the theory itself. It was highly inclusive of the subject being explored as a result, for it was the primary methodology used in order to gain the data to correlate the theory and gain proof for the theory itself. The theoretical framework present was the benefit of clinically induced hypothermia on cardiac arrest patients outside of a clinical trial, directly relating to the question that the paper itself strives to answer. It is clearly detailed in the first and second paragraphs of the research article itself, and is used to provide the setting for the remainder of the paper itself. The specific sample method and sample size is not identified; however, the process used to determine if a study could be used as a part of the data for this particular study is detailed. The participants identified for the study were included or excluded on the basis of only a few qualifiers. â€Å"

Financial Performance of Pace Leisurewear Ltd Case Study

Financial Performance of Pace Leisurewear Ltd - Case Study Example Financial statement analysis involves, comparing the performance with that of other firms in the same industry and evaluating trends in the firm's financial position over time. These studies help management identify deficiencies and then take actions to improve performance. For evaluating the financial performance of the firm ratio analysis and Du Pont system are used. According to Fraser, L. (2001) & Ormiston, A. (2001) the subordinate classifications of ratio analysis are: According to Fraser, L. (2001) & Ormiston, A. (2001) The available cash resources to satisfy the current obligations must come primarily from cash or the conversation to cash from of other current asset. For interpreting the liquidity of the firm, several types of ratios have been depicted. Current ratio, quick ratio, cash flow liquidity measures the firm's short-term solvency. Firm's ability to meet the current obligations can be judged. Liquidity position or effects of using debt can be evaluated. The available cash resources to satisfy the current obligations must come primarily from cash or the conversation to cash from of other current asset. To judge the long-term financial position of the firm, financial leverage ratios are used. Brigham, E. (2007) & Houston, J. (2007) mentioned that these ratios indicate mix of funds provided by owner and lender. According to Fraser, L. (2001) & Ormiston, A. (2001) the amount and proportion of debt in a company's capital structure is extreme ly important because of the trade off between risk and return. Gross profit margin, operating profit margin, and net profit margin represent the firm's ability to translate sales dollars into profits as different stages of measurement. Administrative efficiency can be judged through this. Brigham, E. (2007) & Houston, J. (2007) assessed the fixed asset turnover ratio measures how effectively the firm uses its fixed assets and total asset turnover measures the turnover of the entire firm's asset. So, Debt ratio, debt to equity ratio, long tem debt to total capitalization ratio have been drawn. Ratio Analysis: Liquidity Ratio: Short-term Solvency Year before last Last year Current 1.76 1.13 Quick 1.10 0.47 Cash flow liquidity 0.30 The current ratio of the firm indicates that at the end of year current asset covered current liabilities 1.13

GMF and Effects on Human Health Essay -- genetic engineering genetical

Effects on Human Health   Ã‚  Ã‚  Ã‚  Ã‚   With the way technology has grown, especially in the field of genetic engineering, has led scientists to figure out a way to alter how food is made. This raises concerns and lot of questions regarding the methods they are using. From what possible side effects can occur to the risks it poses to everyone and everything. Unfortunately, there has been limited research and testing done. With that in mind there is not enough information available about the hazards of genetically modified foods. But, what we do know is alarming. Most of the debate surrounding GM foods are focus on the following three issues: 1. Human and environmental safety, 2. Labeling , and 3. Consumer choice. In this section of the paper I will be discussing how genetically modified food can be dangerous on the health of humans.   Ã‚  Ã‚  Ã‚  Ã‚   First we will start with the definition of Genetically Modified (GM) is â€Å"a special set of technologies that alter the genetic makeup of such living organisms as animals, plants, or bacteria. Biotechnology, a more general term, refers to using living organisms or their components, such as enzymes, to make products that include medicines and vaccines, foods and food ingredients, feeds, and fibers†.   Ã‚  Ã‚  Ã‚  Ã‚   The unique structure of GM food creates risk to humans which can affect them in the following ways: allergic reactions, toxicity, antibiotic resistance, adverse health side effects and death. It is impossible to foresee the damage inflicted ...

Apples Eat Themselves, Law421

Article Review LAW 421 March 25, 2013 University of Phoenix Material Article Review Format Guide MEMORANDUM UNIVERSITY OF PHOENIX DATE: March 25, 2013 TO: Timothy Morris FROM: Debra Aguilar, Brady Benton, Karena Busch, Stephanie Hudson, and Rachel Wichert RE: Apples Eat Themselves ARTICLE SYNOPSIS A review of the legal battles between Apple, a computer company and Apple, a record company, are discussed in this article. Both share a similar logo (an apple) and since 1991, the companies have gone to court to claim the Apple logo should only be unique to one company.In 1991 the Court agreed for each company to continue to use the Apple logo but now, the record company has accused the computer company of not conforming to the terms of the agreement. In 1980, George Harrison noticed an apple in an ad for computers. He thought this infringed upon Apple, the Beatles Record company trademark and filed suit. In 1981, Apple Computer agreed to stay out of the music business. In 1991, Apple Corp . filed suit against Apple Computer for trademark infringement again and settled out of court for 26. 5 million dollars. The two companies divided up the apple universe, indicating where each could use the apple symbol.In 2001, Apple Computer introduced online iTunes Music Store which had a huge impact on the music retail industry. In 2003, Apple Corp. again sued Apple Computer stating music was being stolen from them. Apple Computer was protected because downloads of music are comprised of digital data, and the distribution of digital entertainment content is permitted in the 1991 agreement. Apple computer, now looking from the other side of the dispute, may have issues protecting its own trademark because of current legal action that would force them to share copyright protection software with other companies.The Computer Giant would be forced to make downloads sold on their site playable on any device, not just its own iPod products. This would result in wide open competition, so mething Apple Computer has not faced before. The reason Apple Corp sued Apple Computer over thirty years ago was to protect its trademark, and now Apple Computer may find itself in the same situation. LEGAL ISSUE Apple Corp and Apple Computer have had their share of trademark issues. It’s been about thirty years that Apple Corp and Apple Computers litigated a dispute involving the use of the â€Å"Apple† name as a trademark and its association with music.In 1978 Apple Corp filed a law suit against Apple Computers (Apple Inc) for trademark infringement and eventually agreed to a settlement about two years later with Apple Computer paying out a mass amount to Apple Corps. The legal issue Apple Corps raised is that Apple Computer is involved in the music business and that in the 1991 agreement Apple Computer agreed to stay away from the sound recording industry, committing trademark infringement. In 2001 Apple computer released the iPod as a hardware device that can be us ed to download and play software like music from iTunes.ITunes was released in 2003. Apple Corps claims that Apple Computer is involved in the sound recording industry by the use of the iPod and the music downloads from iTunes that is in violation of the 1991 agreement in which Apple Computer would not have any business dealings that had to do with the sound recording industry. The High Court ruled that, â€Å"The Apple Computer hadn't breached the terms of the agreement and could continue to operate their computer business as usual. †(BBC News, 2006). For years Apple Inc has battled with Apple Corp over trademark issues.In 2007, they finally reached a settlement that determined Apple Inc. would own all trademarks and logos related to the name â€Å"Apple† and would license them accordingly to the Apple Corps music company (Tibken, 2012). During the time of the agreement, Apple’s CEO Steve Jobs commenting on the settlement stated â€Å"We love The Beatles, and it has been painful being at odds with them over these trademarks. † Jobs added that â€Å"it feels great to resolve this in a positive manner, and in a way that should remove the potential of further disagreements in the future. MANAGERIAL PERSPECTIVE The legal issues in this article can affect the business deeply. The main factor is the loss they can occur in sales due to the music company saying they are not following the contract they have put forth. This shows customers and people of the world that their company is not trust worthy in all aspects of their business. In many circumstances this can stop people from buying their products until the situation is over and they find out the truth. The issue is that it could take weeks or months to finish the lawsuit.The problems that have happened with Apple the computer company could have been avoided if they took the correct steps allocated in their agreement with Apple the music company. The first step they should have taken was to sit down and have a business meeting with the representatives from the music company and explain to them what they wanted to do so that the contract could be altered. Instead they did it without coming to an agreement first, which disrespected the music company. Legally this is what should have happened so that the contract was followed and no one broke the contract illegally.References Macklem, K. (2006, Apr 10). Apples eat themselves.

Obesity Of People Obesity - 1004 Words

â€Å"One of the major problems that the world is facing today is obesity of people. In the world as of today the United States of America is currently ranked ninth with 33.9 percent of people be obese.America is one of the most obese countries in the world, and the reasons are quite obvious. Just take a look around you. High amounts of stress , more and more technology to make our lives easier (and lazier),fast food chains on every block (unhealthy foods are much less expensive than the healthy foods we should be eating) and are all factors to weight gain in our country.Obesity can be divided into three main causes – diet, lifestyle and education. One of the chief causes is diet. Young Emiratis eat more and more high-carbohydrate, high-fat burgers and pizza in fast-food restaurants. However, some traditional foods are also very oily, and because of increasing affluence are eaten more often than in the past. Lifestyle is a second main cause of obesity.†As a result of cheap foreign labour, many Emiratis now have sedentary jobs, and do not exercise regularly.†However, one of the main causes is lack of education and awareness. The society’s attitude to food often leads to overconsumption. Parents do not teach good eating habits to children, and many people lack knowledge about good nutrition or a balanced diet. In the past 40 years, there has been an expansion to more than 160,000 fast-food restaurants in America.
