Life On Mars - Essay Example These organisms rely on chemical or geothermal energy instead, and it is likely that organisms living on Mars would have to rely on sources of energy similar to these types of organisms; it is very unlikely that there would be any life present on the surface of Mars because the atmosphere contains chemicals known as superoxides, which break down all organic, or carbon-containing molecules, which are the building blocks of life. It is much more likely that if life ever was present, or still is there today, that it would be found under the surface. The signs that we use to look for life on Mars are all based on knowledge that we have of life on Earth. While any life forms found on Earth may not be remotely similar to those found here, it provides a good starting point for the search. All living things on Earth contain the element carbon in their structures, and so this if we find this element on Mars it could signify areas in which life may have developed. From looking at deposits of fossils which chart the history of life on Earth, it can be seen that there are only certain environments in which fossils can be preserved, so if a appropriate set of conditions is found on Mars then it may be a good place to look for fossilized life forms. How do we search for life There have been several expeditions carried out to Mars, but so far all by machinery rather than actual people. In the 1970s, a team of scientists, including Dr. Gilbert Levin, sent two Viking probes up to the surface of Mars to look for signs of life. They conducted tests on the soil to see if organic materials, and possibly life, were present there at the moment, producing controversial results. Since then we have sent several other probes to conduct testing on the soil, and there are a pair of robots there at the moment - Spirit and Opportunity. As well as conducting tests, these robots have been taking photographs that a panel of scientists are studying, which may give further clues as to whether life is there at the moment, how likely it is that life has ever been there, and where best to look for any life that may be present. Dr. Gilbert Levin is also one of the scientists currently involved with this expedition. As of yet there have been no manned missions to Mars, but this ma y change in the future, since there are many scientists who back this idea. Current conclusions At the moment the question as to whether life is present, or has ever been present, on Mars is largely unanswered. Dr. Gilbert Levin concluded in 1997, from the results of the Viking mission, that there is currently life on Mars, in the form of

Comparing Two Arguments Essay Example | Topics and Well Written Essays - 750 words

Comparing Two Arguments - Essay Example He defends the use of animals in scientific experiments. Roger Caras is a well-known photographer and writer. He is known best for being a wildlife preservationist and as a president of the American Society for the Prevention of Cruelty to Animals. Obviously, Caras is on the other side of the fence, defending animals as subjects in scientific experiments. Karpati believes that the use of animals in scientific experiments is a necessary means to discover and understand the different principles, such as biological processes. He agrees that computer simulation may help but it will not be enough to imitate the different processes happening within one’s live body. Thus, it is important to have live subjects to replicate the same processes. He argues that if the use of animals in experimentation is restricted, the scientific research will be greatly impacted. Medicines, surgical techniques and other great innovations may not be discovered for years, even decades. Karpati says he doe s not advocate a cruel treatment to animals, rather he wants the public, and the animal rights movement, to ponder on whether to choose using animals to discover treatments for the illness of a child or to let a sick child die without attempting to treat him. Caras, on the other hand, argues that animals have rights and we don’t have the right to inflict pain and suffering on them. We should not be treating animals as properties that we can do anything we want to. Caras believes that there is a pressing need to find alternatives to animals when doing scientific research. His argument focuses on the quest to discover other means on how scientific research can effectively simulate the needed information gathered from live bodies. Different with other animal rights advocate, he attempts to direct the public in resolving the conflict by looking for alternatives rather than by just arguing not to use animals or to continue using them as live subjects. While Karpati defends his poi nt of view, Caras points the reader to a different direction. Caras wants the reader to look for solutions rather than just argue about the issue. Karpati wants the reader to understand that the restriction of animal use might as well be a call to limit scientific research. He does this by enumerating the many effects of limiting the use of animals in research. He says that â€Å"the terrifying effects of the effort to restrict the use of animals in medical research is that the impact will not be felt for years and decades† (Karpati). He continues that drugs, surgical techniques, and fundamental biological processes may not be discovered and understood until years later, and even more that these delays may mean the cost of many lives. Karpati defends himself by saying he does not advocate animal cruelty. In fact, he believes that the animal rights movement has made a significant contribution in making the scientific community search harder for suitable alternatives for animal experiments. But Caras believes that there is little effort in doing so as it has only recently become an imperative for the scientific community (Caras). Caras points out that even if the scientific community is looking for alternatives, they are not looking hard enough or their efforts are delayed. Caras and Karpati both declares that the scientific co

Final - Essay Example Then, in an essay that synthesizes at least four of the six provided sources for support, take a position that qualifies the claim that GMO should be discouraged because it is a probable health risk and an environmental hazard. This article presents an assessment of the effect GMO technology is having on global agriculture from both economic and environmental perspectives. The article seems to assert that there could be a possibility of having positive economic impact when all factors are put into consideration. This source is significantly resourceful in presenting counterargument when discussing the negative impacts of GMO technology. This article highlights some of the widely argued biomedical risks of GM foods such as potential allergenicity, and most importantly, horizontal gene transfer. The source also discusses the environmental side effects on biodiversity. Since the source also discusses the benefits of the first generation of GM foods, then a good comparison can be made from the same source. This source gives a clear list of reasons why GMOs should not be used. The article highlights little knowledge on GMOs as one of the issues challenging use of GMOs. Increased pesticide use is also a notable cause for alarm on use of GMO. This source gives a quick peek. However, it offers a good start into more indepth research

Ecosystems and Trophic Levels. Tropical Rainforest Assignment

Ecosystems and Trophic Levels. Tropical Rainforest - Assignment Example There is an estimate that approximately 20 to 86 species of trees exist per acre of these forests. Trees lies in several vertical layers named as Emergent layer, Canopy layer, under story layer, shrub layer and ground layer (Davis, 2007). So scientists consider this area as species-richest biomes on this planet that is very unique due to its complex ecosystems. Food Chain: In tropical rainforest there are hundreds of interlinked food chains those when combined result in a complex and huge food web. Tropical rainforests food chain has four levels First level is dominated by plants, fruits, leaves, planktons etc Second level is made up by the herbivores (animals which eat plants) such as insects, small reptiles, nectar eating birds and some large animals such as monkeys, apes etc. Small carnivorous animals (meat eating animals) make the third level and these include rodents, and some small reptiles. Large carnivorous animals such as snakes make the fourth level. Last and fifth level is dominated by the large dangerous carnivores such as pythons, alligators tigers etc. Symbiotic Relationships and energy transfer within various levels: Life in tropical rainforest is difficult and there is a strong competition between different species. Hundreds of species have developed symbiotic relationship with other species in order to survive in such a highly competitive environment. In a symbiotic relationship both species are mutually benefited. ... Primary producers also named as autotrophs are the only living being which use the sunlight energy to convert carbon dioxide and water into carbohydrates (Pipe, 2008). Then comes primary consumers, which consume autotrophs and utilize their energy for their living. In this way energy is transferred from one level to next level. In energy pyramid third and fourth level is occupied by secondary and tertiary consumers. Secondary consumer depends on plants as well as on primary consumers for their energy requirement whereas secondary consumers (carnivore) feed on secondary consumers (Davis, 2007). As energy is transferred from one level to another, it becomes lesser in amount as some energy is lost as heat energy. Indeed only 1.2% of energy is transmitted to the next higher level in this energy pyramid. Decomposers or detritivores form the last level of energy pyramid. Detritivore include bacteria, fungi and virus. And these are the organisms which nourish on dead plants and animals and derive energy by decomposing these dead bodies. In this way they change the complex organic substances of the dead bodies into their simpler form that is further utilized by the plants to synthesize their food. In this way decomposers serve as a link between autotrophs and consumers. Decomposers also serve to clean the environment (Pipe, 2008). Human interference: This valuable resource of earth is under threat due to human activities. Extension in human settlements, need for the more and more agricultural land, construction of roads and need of wood have resulted in quick deforestation of this tropical rainforest. As a result of this deforestation large area has lost its vegetative cover as well hundreds of thousands of other species that inhabited or

What is the study design? What criteria did you use to determine the study design? It is a Quantitative. In the research there are numbers that indicate temperature regulation as variables. The study tests the patient’s core body temperature in the operating room when they are under anesthesia and with controlling the room temperature during surgery. The criteria I used out of this study were to determine the study design was that numbers were used in this study. The research was using a relationship between variables, the temperature of men vs. women and also the time that the person was in the operating room in and under sedation. There was documentation done in a drop of core temperature the longer the person was sedated and in the operating room. 2 How did you confirm that the journal you selected was peer-reviewed or germinal? I determined that the journal article was peer-reviewed because I selected  peer-reviewed form the EBSCO host database and it came from a credited web base. In the publication it also states that it is peer-reviewed. 3 Does this research article generate support for evidence-based practice? If not, state why it does not. Please review the critical appraisal guideline on pg. 466-480. It does provide evidence based research, In the article it describes ways of warming to prevent hypothermia in the operating room all based on research to keeping patients with warm fluids and warm blankets and monitoring the core temperature of the patient while they are sedated.

Models of Accounting Analysis

Models of Accounting Analysis Historic Cost In accounting, historic cost is the first money related quality of a financial item. Historic cost is focused around the stable measuring unit assumption. In a few circumstances, assets and liabilities may be demonstrated at their historic cost, as though there had been no change in value from the date of acquisition. The balance sheet value items may subsequently vary from the accurate value (WIKIPEDIA). Principle An accounting system in which assets are recorded on an balance sheet with the value at which they were obtained, rather than the current market value. The historic cost standard is used to get the measure of capital expended to acquire an asset, and is helpful for matching against changes in profits or expenses identifying with the asset purchased, and in addition for deciding past opportunity costs (Business Dictionary). Impacts Under the historical cost basis of accounting, assets and liabilities are recorded at their values when first acquired. They are not then generally restated for changes in values. Costs recorded in the Income Statement are based on the historical cost of items sold or used, rather than their replacement costs (WIKIPEDIA). Example The main headquarters of a company, which includes the land and building, was bought for $100,000 in 1945, and its expected market value today is $30 million. The asset is still recorded on the balance sheet at $100,000 (INVESTOPEDIA). Current Purchasing Power Accounting Capital maintenance in units of constant purchasing power (CMUCPP) is the International Accounting Standards Board (IASB) basic accounting model originally authorized in IFRS in 1989 as an alternative to traditional historical cost accounting (WIKIPEDIA). Principle Current Purchasing Power Accounting(CPPA) includes the re-statement of historical figures at current purchasing power. For this reason, historic figures must be multiple by conversion factors. The formula for the calculation of conversion component is: Conversion factor = Price Index at the date of Conversion/Price Index at the date of item arose Conversion factor at the beginning = Price Index at the end/Price Index at the beginning Conversion factor at an average = Price Index at the end/Average Price Index Conversion factor at the end = Price Index at the end/Price Index at the end Average Price Index = Price Index at beginning + Price Index at the end/2 CPP Value = Historical value X Conversion factor (Account Managment Economics). Impacts on Financial Statements financial statements are ready on the basis of historical cost and a supplementary statement is ready showing historical items in terms of present value on the basis of general price index. Retail price index or wholesale price index is taken as an appropriate index for the conversion of historical cost items to show the changes in value of money. This method takes into consideration the changes in the value of items as a result of general price level, but it does not account for changes in the value of individual items (Accounting Managment). Example XYZ Company had a closing balance of inventory at 30 June 2012 equal to $10000. This inventory had been purchased in the last three months of the financial year. Assume the general price level index was 140 on 1 July 2011, 144 on 31 December 2011, 150 on 30 June 2012, the average for the year (July 2011-June 2012) was 145 and the average for April 2012 June 2012 was 147. For showing updated inventory with CPPA, we will use following formula Book value of inventory X current month general price index/ average index of three months = 10000 X 150/ 147 = $ 10204 (Accounting Education). Current Cost Accounting Current cost accounting is a procedure of accounting that attempts to give quality of benefits on the basis of their current replacement require as opposed to the sum they were purchased for (Ask). Principles It influences all the records and accounting reports also their balancing items. A fundamental principle underlying the estimation of gross value added, and hence GDP, is that yield and intermediate utilization must be value at the costs present at the time the processing happens. This intimates that goods withdrawn from inventories must be value at the price prevailing at the times the goods are withdrawn and not at the costs at which they entered inventories (Glossary Of Statistical Terms). Impacts Accounting systems that help in the preparation of financial reports, the cost accounting systems and reports are not subject to rules and standards like the Generally Accepted Accounting Principles. As a result, there is huge variety in the cost accounting systems of the different organization and sometimes even in different parts of the same organization (WIKIPEDIA). Advantages Of Historic Cost Historic Cost provide straight forward procedure. It records gains until they are recognize. Historical Costing method are still using in accounting system. Dis-Advantages Of Historic Cost Historic Cost consider as a acquisition cost of an asset and does not recognize current market value. Historic Cost only interested in allocation of cost, not in the value of an asset. It’s neglect the current market value of the asset that may be higher or lower than its suggested. It’s gives flaws in time of inflation (Study Mode). Comments Historical Costing method is still using in accounting system, it is a traditional method of accounting system it is not represent the market value of items, due to which it is not a appropriate method to adopt. Advantages Of Current Purchasing Power Accounting Current purchasing power method uses as measuring unit. It’s provide the calculation facilities to gain or loss in purchasing power due to holding monetary items. In this method, historical accounts continue to be maintained because they prepared on supplementary basis. This method intact the purchasing power of capital contributed by shareholders, so the method is important from the shareholders point of view. This method provides reliable financial information for the management to formulate policies and plans. Dis-Advantages Of Current Purchasing Power Accounting This method is only consider changes in general purchasing power, it does not consider the changes in the value of individual items. This method based on statistical index number which not used in individual firm. It’s difficult to use suitable price index. This method is failed to remove all defects of historical cost accounting system (Accounting Management). Comments Purchasing power accounting is very useful to provide financial information for management and its intact the purchasing power of capital which contributed by shareholders, its useful in inflation time so now in current time this method is very useful. Advantages of Current Cost Accounting This methods use present value of assets, instead of the original purchase price. This type of accounting is addresses the difference between historical and current cost accounting system. This method assigns higher values on the assets owned by the business. This method also used during bankruptcy and liquidation procedures to find the total loss to the owner (Ask). Comments Cost accounting provides accurate situation of the connection between specific cost and specific outputs because traces resources as they moves through company. By adopting cost accounting for business, in that way we learn resources are being wasted and which resource are most profitable (Chron).
