Geochemistry Physics - Coursework Example Mechanical infiltration also plays a vital part in the downward movement of clay sized particles. Carbonate rocks such as limestone are affected by inversion, recrystallisation and grain growth as well. Typical processes that affect carbonate rocks are (sequentially) biochemical degradation, polycondensation and insolubilisation. 2. Why is the smectite to illite transition important in the process of petroleum formation? The smectite to illite transition is an important diagenesis reaction especially for shales with progressive burial. This transformation has the potential to flush hydrocarbons from various shales, accelerating the generation of hydrocarbons, producing high pore fluid pressures and for provision of various cementation agents to different sandstones. 3. How would you expect the alkane/alkene ratio to change as a hydrocarbon mixture matures over geological time, and why? The alkane/alkene ratio would tend to decrease with time as a hydrocarbon mixture matures over geol ogical time. This would take place as the biodegradation process would tend to remove alkanes so that the hydrocarbon mixture moves towards aromatics. 4. ... 5. What is a geochemical fossil? A geochemical fossil is the remains of any organic object that has been transformed by diagenesis into a fossilised state. The resulting fossilised state may not have been able to preserve the original structure of the fossilised object. 6. Explain how crude oils can be grouped based on their sulfur content. Crude oils are classified using sulphur content such that low sulphur content crude oils are known as â€Å"sweet† while high sulphur content crude oils are known as â€Å"sour†. Typically low sulphur content crude oils are preferred because sulphur tends to display acidic behaviour. PART 2. 1. Draw the van Krevelen diagram and explain how it illustrates several important facts concerning the formation of petroleum. A van Krevelen diagram is generally plotted to evaluate the origins and maturity levels of kerogen and petroleum content. The van Krevelen diagram plots the ratio of hydrogen to carbon against the ratio for oxygen to carb on. Figure 1 - van Krevelen diagram sourced from (Monash University, 2008) Looking at the diagram above, it becomes obvious that the van Krevelen diagram differentiates between various hydrocarbon products depending on certain regions on the plot. The formation of liquid petroleum can be seen as resting between oxygenated products and gas products which signifies petroleum formation. Additionally the van Krevelen diagram illustrates the evolution paths of various kerogens through the various paths shown on the plot. The plot above shows four possible paths (I, II, III and IV) that denote increasing burial. Based on this the particular mix of petroleum obtainable is arrived at. 2. What is

Company Law Essay Example | Topics and Well Written Essays - 1500 words - 2

Company Law - Essay Example However, advertisements are not always perceived to be offers that can legally bind the advertiser of a product. Advertisements are usually considered as invitation to treat. Miller and Jentz (2008), argue that advertisements are invitations for tenders or business deals and do not in anyway constitute a contract. Nonetheless, there are instances when an advertisement can constitute an offer. An advertisement becomes an offer when its terms are definite and the advertisement portrays the intent of entering into a legal relationship by the advertiser (Furmston, Tolhurst & Mik 2010; Miller & Jentz 2008). In such a case, the offeree has the power to transform the advertisement into a valid and binding contract through acceptance of the offer (Jennings 2013). The offer can however be terminated by the subsequent action of either the offeror or the offeree via rejection, revocation or even issuing a counteroffer (Miller & Jentz 2008; Evans 1995). As such, advising William necessitates dee p understanding of the elements that constitute to a legal and binding contract. ... William decided to advertise the vase on Monday offering it for sale for ?1500 or nearest offer. On Wednesday, Nigel, who did not contact William since their meeting on Sunday, posted a letter to William stating his acceptance of William’s offer of ?1200. Does a valid and legally binding contract exist between William and Nigel? In this case, there exist no legal contract between William and Nigel. As such, William is not in anyway liable to pay any form of damage to Nigel should Nigel decide to take the matter to a court. The advertisement put by William is merely an invitation to the public for a deal. It does not bind William to anyone who might be interested in buying the vase. If it were to be legally binding, it would mean that William is liable and legally bounded by the advertisement to all people with interest in the vase. This advice is based on the decision in the case of Partridge v Crittenden (1968). In this case, the defendant advertised in a section of a magazin e the sale of some bramble finches. Based on the provisions of Section 6 of the Protection of Birds Act 1954, the defendant was incarcerated for selling the birds for it was contravening the Act. However, he appealed his conviction. It was held that the defendant conviction was overturned arguing that the advertisement was an invitation to treat rather than an offer. Also, in the case of Harvey v Facey (1893), Privy Council, it was held that a mere statement of price does not amount to a contract. The court held that by stating the price, the defendant was merely providing information and that no valid and legally binding contract existed (Ibrahim, Ababneh & Tahat 2007; Moles n.d). Further, William’s advertisement is not definite in its terms, which would bind him to

Sir Richard Branson, Chairman, Virgin Group, LTD Research Paper

Sir Richard Branson, Chairman, Virgin Group, LTD - Research Paper Example The entrepreneur is described to be a risk taker, but also with ability to turn the impossible into business opportunities. More on his mass investment in entertainment, transport, telephone services, and financial sector is elaborated. He also demonstrates his leadership skills, while dealing with his employees, customers, society, and his different businesses by close association, partnerships, and participation. Keywords: Business, Enterprise, Entrepreneur, Leadership Skills, Ideas, Motivation, Investment, Opportunities, Evolution, Virgin Atlantic Airlines, Virgin Mobile, Music Label, Employees, Global Warming Introduction The ability to be a successful individual in society is viewed differently according to individuals, or a collective perception of people. Today everyone associates success with education, learning and gathering information, but opposing, excelling and living a satisfactory life needs the basics of wisdom, understanding and hard work, if not working smart. Sir R ichard Branson’s history exists to confirm this. People tend to strain in life, as they force themselves in situations where they do not fit; it is not really the sharpness of a student in class that determines his or her future. The idea is that, ‘people are totally different, with diverse abilities and interests’. ... He possesses the qualities of a great leader, which most businesses in the world lack, leading to their failure. Interest, Idea and Ambition in Business Different nations have various ways to nurture the young population in paths of their careers. At least academicians are now concentrating on this, unlike in the past where education was so generalized. Branson’s venture into business occurred in his childhood, at the age of 15 years, he began producing and selling magazines in his school, before dropping out at 17 years of age to fully participate in his business (Mills et al., 2007, p. 485). His entrepreneurial skills outweighed the impact of education in his life, but on the bright side he began nurturing his career early in life. He turned the business idea into a fact, hence bringing an impact into the market through his innovation and creativity. According to Schmidt and Ludlow, â€Å"Starting a magazine for young people, Student, he already had the idea that the concep t could cover many other products and services for young people: a student travel service, perhaps a bank† (2002, p. 130). His business venture in school was strategic, not that other individuals could not come up with another proposal, but because he took advantage of the market niche, combined with his wisdom and tactics to flourish at young age. Earlier on, he seemed to struggle with his studies especially with the rigid school rules, which most students also have to tolerate in the education systems. Convinced on his entrepreneurial step, he only got to begin with 4 dollars as his capital, with Jonny James as the only supporter, before his head teacher finally accepted his successful progress (â€Å"The success story,† 2008). His venture in business was humble,

Large Scale Universe Essay Example for Free

Large Scale Universe Essay Cosmology, as defined by Encarta Dictionary is â€Å"the philosophical study of the nature of the universe. † This concern with viewing the universe and its vast issues and meaning takes the mind into a mysterious spectrum. The very foundation of Cosmology began with Astronomer Edwin Hubble in 1929. He discovered that other galaxies existed in the universe and determined that these galaxies were moving away from each other at a rate that was constant with the distance between them. The farther away from Earth the galaxy was, the faster they would be traveling away from us. In theory, this also proved that universe was expanding. This discovery assisted the profound astronomer with formulating Hubble’s Law, which directly contributed to giving astronomers the keys to discovering how old our universe is and proving that the universe is expanding. The Big Bang theory is the most notable theory about the creation of our universe, which happened more than 14 billion years ago. The process began to expand from particles released from the superior explosion and dropping temperatures. The process started as a small speck of matter and formed into a dense object as large as Earth from radiant energy and exotic particles called quarks or antiquarks. As the temperature dropped during this process, things such as protons and neutrons began to form together creating helium nuclei over a period of a few hundred thousand years. More than two billion years after the Big Bang, galaxies began to form as gravity started to collect and mass together irregular matter forming a sponge type structure. Our galaxy, the Milky Way, forms one billion years after this mark. Star clusters form from inside a giant sphere of gas and spiral arms take shape as settling gas forms into a disk shape displaying a centered core like formation. One example scientist conducted to prove the Big Bang Theory were scientist Arno Penzias and Robert Wilson, who discovered cosmic microwave radiation in 1965 from the Holmdel antenna in New Jersey. They discovered that residue left over from the Big Bang explosion was forming low-level radiation pockets throughout the universe. This discovery along with Hubbles Law stating that galaxies were traveling away from us, builds a sturdy case in support of the big bang theory. The Milky Way galaxy is only one out of billions of galaxies floating throughout this vast space. It is flat in shape with a central bulge spiral shaped galaxy that carries more than 100 billion stars and is 100,000 light years in diameter. According to the Cosmic Perspective, â€Å"If dark matter is indeed the most common form of massing galaxies, it must have provided most of the gravitational attraction responsible for creating the protogalactic clouds. The hydrogen and helium gas in the protogalactic clouds collapsed inward and gave birth to stars, while weakly interacting dark matter remained in the outskirts because of its inability to radiate away orbital energy. According to this model, the luminous matter in each galaxy must still be nestled inside the larger cocoon of dark matter that initiated the galaxy’s formation, just as observational evidence seems to suggest. † Dark energy, discovered in 1998 by a team of three Astronomers, Saul Perlmutter, Brian Schmidt and Adam Riess, observed exploding stars to gather numbers for data to support the expanding universe. While attempting to grasp a better understanding of supernovae’s, they stumbled across evidence that supported the universe was expanding, but at an accelerated pace. This discovery, in an ongoing effort, changed our view of the expanding universe. Scientist do not know exactly why the universe is expanding at this rate, but dark energy seems to be forcing galaxies and large amounts of matter apart. The destiny of our universe relies on whether gravity can hold this force back from expanding rapidly. However, evidence shows that gravity is growing weaker even when matter is factored in. This proves that the rapidly expanding universe is not only increasing, but also will not stop increasing. The Theory of Everything stated by Brian Greene, is the theory to end theories. He states, â€Å"For the first time in the history of physics we therefore have a framework with the capacity to explain every fundamental feature upon which the universe is constructed. For this reason string theory is sometimes described as possibly being the, theory of everything (T. O. E. ) or the ultimate or final theory. These grandiose descriptive terms are meant to signify the deepest possible theory of physics—a theory that underlies all others, one that does not require or even allow for a deeper explanatory base† (Brian Greene, Theory of Everything, October 28, 2003). This theory projects a meaning for everything created in the universe down to the smallest particle all the way up to the largest particle, including all matter and its fundamental principles would be explained down to the deepest explanation at microscopic levels. This final theory would represent an unwavering support of rationality that would forever declare that the universe is an absolute intelligent source.

observing smoking reducing stress and anxiety

observing smoking reducing stress and anxiety To observe either smoking reduces stress and anxiety. Like mostly smokers said that when they are under stress or anxiety and they smoke a cigarette then their stress relieved and they feel fresh and relaxed. In my research I would like to find either this is true or not. To observe persons psychological condition with smoking habit. In many studies it is shown that smoking habbit is also related to mental condition. I would like to find that students who smoke, whats their perspectives for smoking. To observe does smoking affects the general health of a person. I would like to find out whether the students who smoke have some health problem or not. Are they having any health problem after they starts smoking? Introduction Smoking is to inhale smoke of burning tobacco in the form of cigarettes, cigars etc. Some people occasionally smoke to relief their stress but smoking, as a habit is a physical addiction. Habitual smoking is also called psychological addiction by health experts. In the whole world, almost in every nation there is a warning written on every packet of cigarette that it is injurious to health. In spite of that lot of people find smoking is quite attractive. In UK approximately 120,000 people died every year due to smoking. Smoking is the major reason for sickness and early deaths. On an average non smokers live 10 yrs more than the smokers (webarchieve.nationalarchives.govt.uk.).So a smoker dies 10 yrs early as compare to a person who never smoke in his life. Tobacco contains more than 4000 chemicals, 69 of which known to produce cancer.90% lung cancer deaths are due to smoking. Main three components of tobacco are-nicotine, carbon monoxide and tar. All three of them cause diseases. Nic otine absorbs in blood stream and effected brain in 10 seconds. If a person is habitual smoker, whenever the level of nicotine drops in blood, withdrawal symptoms like craving, anxiety, restlessness, headaches arises. These are relieved when the person smokes. Thats why person smokes regularly to keep these symptoms away. Otherwise the smoker becomes anxious and irritable because of the withdrawal effect of nicotine. Tar contains many contents which produce cancer. Tar contains irritants which damage the lungs which are a major vital organ of human body; by constricting the bronchioles and destroying the cilias which protect lungs from dirt and other infections. Smokers do not sit long hours for doing their work, they need a cigarette break. With this, they feel relaxed and energetic to do their work. People usually smoke at different times in a day .Smokers thought the situations which are not positive; they made them less stressful with smoking a cigarette. Smokers feel pleasure i n smoking. But smoking produce critical health risks for smokers and the persons surrounding them. Because the family members and friends of a smoker who breathe second hand smoke also harm their general health. In this proposal we discuss about the smoking and its perceptions among university students. We discuss the facts that why students attract towards smoking. Does smoking really help to reduce the stress in students? Does smoking affect their general health? These all we discuss in our research proposal. Literature Review According to Stephen J. Heishman (1999), the 3 factors which influences smoking or are influenced by smoking habit, are stress, weight gain and performance. Addiction of nicotine is very complex process which includes biological, psychological and other factors also. If nicotine addicted person withhold nicotine, his attentional and cognitive abilities would be diminished, but these are reversed if nicotine is given to that person. In stress, smoking is eminent, but there is not any specified evidence that smoking reduces stress. In average the weight of smokers is 3-4kgs less than peoples who dont smoke and after quitting smoking weight gain is also in same manner. According to Carol Brown (2004) the use of tobacco is high in people having mental health problems. Use of tobacco is one of the preventable causes of bad health and early deaths in Scotland. According to Scottish Executive (2000), nearly 13,000 persons died each year from diseases occurs due to tobacco like diseases of heart and cancers of different parts of body (Callum, 1998).According to ASH Scotland (2004), there are many critical health risks related to passive smoking. In Scotland, sickness related to smoking costs the National Health Service around  £ 200 million per year. According to McNeill (2001), smoking risk is more among persons with mental health problems as compare to other people. According to Meltzer et al. (1996), surveys shows smoking rates were higher in people having mental problems like in people suffering from psychosis than general population. According to Wendy Wang and Paul Taylor(April8,2008),when smokers asked for their habit of smoking they usually say ,it relives our stress, but 50% of them experience stress frequently as compare to others who never smoke or smoke once and now quits. The survey also shows that smokers are more sad and unhealthy as compare to non smokers or persons who quit smoking.45% of smokers said that they are healthy as this percentage was63%in non smokers and little less in former smokers. Six out of ten current smokers satisfied with their family life whereas this ratio was seven in ten in non smokers. Satisfaction in job is also low in current smokers. According to Andy C Parrott (1999), smokers oftentimes say that smoking helps to relieve their stress whereas the level of stress is quite more in smokers. Dependency on nicotine looks as to modify stress. This resulted irregular mood pattern shown by smokers, during smoking they have good moods and bad otherwise when not smoking. The smokers require nicotine for feeling normal. According to Piasecki (2006) addiction rate is very high in tobacco smoking. Likewise withdrawal of nicotine, tonic desire is basic reason for ex-smokers, who were struggling to maintain abstinence. If a person strike again and again with high stress levels his smoking habbit also raised(Steptoe,et al. ,1996) and stressful activities were essential risk factors for chances of relapse in former smokers(Cohen and Lichtenstein,1990;Mckee,et al.,2003).Study in human laboratories shows that exposure to stress or imagination of provoked markers raises the desire of smoking in smokers who are habitual(Perkins and Grobe,1992;Erblich,et al.,2003). According to American Journal of health behaviour (2006) vol.30 (3), the usage of tobacco in US is highest in adults between 18-24 yrs of age. Most of them are college students. Use of cigarette smoking increased by 28% in the year between 1993-1997. Around 50% of college students tried smoking within that previous year and around 1/3rd are using tobacco currently. Approximately 70% of students of colleges tried tobacco in their life. A recently done study of 224 students of college showed the tendency to take risk, depression, self efficacy were decisive of smoking behaviour. Other study of 636 adult students shows that the college students using tobacco shows lower physical activities and raised depression symptoms as compare to non smokers. Moreover young adults who are in depression use tobacco for improvement in their mood. According to Wegner, Schneider, Carter and White (1987) numerous studies shows inhibiting negative or indifferent thoughts having a rebound effect. So if a person suppresses a single thought he may think about, that thought comes in his mind more quickly. For example people usually attempt to discontinue smoking by avoiding thinking about smoking. Whereas this strategy rises his thoughts of smoking and makes quitting difficult. According to Salkovskis and Reynolds (1994) study, in which contestants decrease or give up smoking by observing their thoughts about smoking. The study shows suppression, raised thoughts of smoking comparison to monitoring. However these results show that thoughts suppression made quitting much challenging. But in this study they were not said that suppression raises smoking. According to Heath Martin (1993); Chassin et al. (1994, 1996) ,Kendler et al.(1999) so many studies done in past two decades suggested that people with the history of smoking in their close relatives were continual smokers than other ones who had no history in their family. Several studies showed that persistent smoking habbit definitely had heritable element. For e.g. Heath Martin (1993) found heritability approximately of 0.53, whereas Kendler et al. (1999) found it as 0.72. These studies show the value of environmental and hereditary factors in habbit of persistent smoking but this did not clarify mechanism that shows relationship of family history and persistence. Hypotheses Smokers thought that smoking reduce stress. Smoking plays a chief role in mood elevation of a person. Generally if the parents smoke, their adult children are more attract towards smoking habit. The family members and friends of a smoker, who breathe the secondhand smoke, also harm their general health. Method Design: This is a Quantitative study of smoking habit and its perceptions among the university students. It is in the form of questionnaire. Dependent Variable: Stress, Psychological status Independent Variable: Age, Gender, smoking habit Participants: The participants are mostly the students of University of Bedfordshire who belongs to different religions and different nations. There will be 25 participants, in which 20 would be male participants and 5 would be female participants. The age of the participants is between 20-40yrs. Procedure: Each student gives a full questionnaire in which options are there and they have to tick the best option according to their choice and they are requested to give answers wisely. Questionnaire is given to each participant personally and told him or her the purpose of test. Before the participants fill the questionnaire, total information regarding the purpose of study and other related information will be given to each participant. This information is also given to the participants that this data remains confidential. This collected data will be used only for study and research purposes and not given to any other organization. After the general introduction regarding name gender etc. the participants asked to select the category of smoking-smoking in the present time, or smoking in the past years and now quitted. Then they start the main Questionnaire. Data analysis The data is collected from students of University of Bedfordshire and analyzed by SSPS. Either a significant relation exists in between the variables is studied by ANOVA. Ethical Consideration The university has accepted the request of survey in their campus. The participants are clearly mentioned about data protection and told them that this data will be used for study and research purpose only. The participants are clearly mentioned that they are free to ask any type of question before the data collection. This is clearly told to the participants if they have any problem during the research they can withdraw any time .The data collected from the students is not given any other party.

Jackie Robinson :: essays research papers

Jackie Robinson: Breaking the Color Barrier It’s April 15, 1947 opening day at Ebbets Field, Brooklyn. Many people have turned out to see one man, the first black person to ever play in major league baseball. He is setting new standards for all blacks now and those to come. His name is Jack Roosevelt Robinson. We all wish him well and hope he can surmount the racial differences. At this time it was unheard of to have a black person treated equally to a white person, more the less it was highly unlikely to have a black person play on the same field as a white person. But for one man who stands alone Jackie Robinson’s conquest to break through the color barrier with the help of Branch Rickey has set new standards for all black athlete’s to come. Jackie Robinson grew up in Cairo, Georgia. Jackie attended UCLA where he played baseball, basketball, football, and track. After collage Jackie enrolled in world war two. After the war Jackie got an honorable discharge. After the end of the war Jackie didn’t know what he wanted to do and he was very short on money. Finally Jackie decided he wanted to join the Negro Leagues. In 1944 Jackie officially was on a Negro baseball team.(Shorto,Russell p. 5-10) In 1945 Branch Rickey the owner of the Brooklyn Dodgers was looking for a black player to break the serration barrier and rise above it all and join the Major League Baseball Association. Rickey said that whoever the person was to be would have to cope with taunts and insult, with name calling and abuse. Rickey heard of the success of Jackie on the Negro League and sent his scouts to see Jackie. (Ritter, S. Lawrence p. 43-51). After a long meeting with Rickey, Jackie agreed to join the Brooklyn organization. Rickey singed Robinson to a Minor League deal in 1945. Jackie’s biggest challenge would be to overcome racial issues sought toward him without acting out with everybody looking at him. Jackie had death threats, racial slur’s, and people wanting to seriously take him out of the game of baseball. (Rampersad Arnold p. 176) In 1947 Rickey called up Jackie to compete on a Major League level and take his career to a much higher level. When people heard of this, that Jackie was going to play on a Major League level players said that if Jackie was going to play they would strike, even some of Jackie’s teammates demanded to be traded
