Ways To Increase Return On Assets Essay Example | Topics and Well Written Essays - 2000 words
Ways To Increase Return On Assets - Essay Example Since both sets of figures show similarity in the total expenses at à £15,400 each, although Set B fails to present the break down of the expenses, then using the said expenses as criterion could not be deemed to indicate a material difference for purposes of inferring which of the two would or would not show a true and fair value. It is, therefore, the matter of the closing stock that will settle the issue of which set does or does not present a true and fair view since it is in the value of the closing where the two sets of figures materially differ. By taking the difference of à £14,000 and à £10,000, one will get a difference of à £4,000 which represents about 40% and which could be now considered by auditors as material misstatement in the financial statement. As to why it affects materially the financial statements will be seen in the income statement and the balance sheet. The income statement is affected because closing stock or inventory takes the nature of revenues in t he income statement as will be explained later. The balance sheet is also affected because the closing stock is part of the current assets and total assets which are parts the computation of liquidity using current ratio and the profitability using the return on assets. Since it affects the net income, the other ratios where net income is used will also be affected.à As to how the material misstatement will affect the profitability ratios may be illustrated as follows: First, the closing stock is important in the computation of gross profit ratio (GPR) which is computed by dividing gross profit by the total sales. It must be noted that the closing stock affects the value of the cost of sales to be deducted from total sales to arrive at the gross profit.

Microeconomics Essay Example | Topics and Well Written Essays - 250 words - 8
Microeconomics - Essay Example I would consider both fixed and variable costs in deciding to go to travel to New York from Los Angeles by either a plane or a car. Fixed costs that I will consider for the trip via plane include cost of an air ticket, luggage fees, and services provided on the journey, which are fixed costs as they have been determined by the airline and do not vary. Transportation costs to and from the airport, traffic and other costs arising after alighting from the plane are among the variable costs for consideration when traveling via plane. Fuel, food at stops, amount of traffic on the road, are the variable costs to be considered for travelling by car while car maintenance, toll fees, any repairs made on the way, parking fees paid in the course of the journey, washing and storage payments, and wear and tear to the car are fixed costs when travelling by car. As is evident, both fixed and variable costs are considered in making the decision on which transport from to use to New York from Los Ang eles. Ruegg, Rosalie T.

Biohybrid Devices Essay Example for Free
Biohybrid Devices Essay Biohybrid devices. Biohybrid devices are implantable medical contraptions that undergo vascularization inside the body before the normal human cells (such as islet cells of Langerhans) can be placed inside them. They provide local immunosuppression that ensures that the normal human cells are not rejected by the hostââ¬â¢s immune system or the graft versus host disease (Dorian). Biohybrid devices can be used to prevent diseases such as liver failure and diabetes. For persons at risk of developing type I diabetes mellitus (such as genetically predisposed individuals) or pre-diabetic individuals, their islets cells of Langerhans can be protected by biohybrid devices (Ricchie). These biohybrid devices are designed using nanoencapsulation technology into conformal polymer biomaterials that form a scaffold over the population of islet cells of Langerhans in the endocrine pancreas; thereby preventing the auto-antibodies from accessing the islets cells, and, causing irreversible injury to the cells by auto-immune reactions that ultimately lead to cell death, and, absolute lack of insulin production (Lucy et al). For the pre-diabetic individuals on immunomodulatory medications, the biohybrid scaffold locally concentrates the drug thus increasing its pharmacologic efficiency and reducing its systemic toxicity. The biohybrid scaffold also improves nutrient distribution across the islet cells and reduces stress encountered by the islet cells of Langerhans (Nazek). Liver failure caused by autoimmune hepatitis can be prevented by biohybrid devices, which form an, intricate conformal scaffold on the hepatocytes surface thereby blocking the auto-antibodies from interacting with the hepatocytes, and, causing immune-mediated liver necrosis (Nazek). Oxygen diffusion is critical for hybrid artificial organs because the normal human cells within them require oxygen for aerobic oxidative respiration and reduced oxygen diffusion may cause hypoxia (a form of cell injury) that leads to impaired physiological processes within the cells and ultimately to cell death(Lemburt et al). This necessitates that the biohybrid device be made of optimal design that allows adequate oxygen diffusion and consumption by the normal human cells (Dorian). These designs are based on experimental mathematical models (Provust). The characteristics that influence the rate of oxygen diffusion across the biohybrid device are geometry (for instance, the spherical organoid biohybrid artificial liver [BAL] was observed to consume oxygen at rates that approximate normal hepatocytes oxygen consumption, while, the hollow tube model of BAL consumed oxygen at rates several magnitudes lower than normal hepatocytes), thickness of the biohybrid device(for instance, models of biohybrid blood vessels made up of hollow fiber scaffold exhibited correlation between increasing scaffold wall thickness and reduced oxygen perfusion) and permeability of the biohybrid device surface to oxygen. This oxygen permeability is a function of the intrinsic property of the polymer that is used to construct the scaffolds of the biohybrid device; also, the nanoencapsulation design influences oxygen permeability albeit to a smaller extent (Silvius). There are several differences between intravascular and extra vascular biohybrid devices as explained below. Intravascular biohybrid devices are placed within the large blood vessels where they act as stents, or, they connect several blood vessels thereby acting as a biocompatible immunoprotective shunts; thus, the normal human cells within such devices obtain nourishment directly from the circulating blood. Extravascular biohybrid devices are placed outside the vascular compartment, for example, planar macro-capsules (extravascular devices) are placed in the peritoneal cavity; the normal human cells in these devices depend on diffusion to obtain the necessary nutrients and oxygen. The extravascular devices are easily implantable and retrievable, but, the intravascular devices would need surgery in order to implant or retrieve them (Triavek). The geometry of biohybrid devices affects their efficiency because the normal human cells within them require an appropriate three-dimensional structure that maximizes the effective surface area in order to obtain adequate nutrition, oxygen and eliminate metabolic wastes. Geometry also influences the population of human cells that can be placed inside a biohybrid device. Geometry of biohybrid device also affects the interaction between the device and the human immune system (Nazek).

The nuclear power
The nuclear power Introduction I am writing this essay to debate the idea of having nuclear power developed for future use by us. This takes on a major issue and covers many aspects of my nations energy use both in present and for the future. When we think about nuclear power we do not automatically think of it as a non renewable energy source. This is because it is not part of the fossils fuels; coal, oil and gas, which we all know will not last us as reliable energy sources for much longer. However, nuclear power is a non renewable energy source and Nuclear energy is considered an important fuel to produce energy How is nuclear energy made? Nuclear energy is obtained by processes of nuclear fission and fusion. In nuclear fission the energy is released by splitting the atom sending a neutron blasting through the nucleus, this makes other neutrons fly off at high speeds setting up a chain reaction. Nuclear fusion is the opposite by which the nuclei of two or more atoms fuse together, in the process mass is lost and this is then converted into energy. Production of energy takes place inside a nuclear reactor which consists of a core surrounded by a thick concrete shield, steam pipes, turbines and a final (electricity) generator. After the mining of the ore (this is mainly uranium or plutonium ore) has been done the pure uranium is turned into uranium dioxide which is made into pellets. Several of these pellets are placed inside fuel rods. Usually there are about 90,000 fuel rods placed in the core of a reactor. Nuclear fission takes place inside the core by which the isotope splits using the atoms in the uranium dioxide from the pellets. The immense heat produced by this is carried away by fluid circulating through the reactor core. Once the fluid becomes heated it is used to produce steam, this steam drives the turbines which in turn rotate the main electricity generators to produce clean, reliable electricity. During this process there is a massive amount of radiation and so this is why the core is surrounded by a thick concrete shield to absorb this radiation. Arguments FOR using and developing nuclear power To satisfy our general needs of heating our water, heating our homes, cooking our food, powering our appliances and lighting our rooms, we need to retrieve energy from the many many methods available to us. One of these choices is nuclear energy. There are very good reasons why it should be considered and developed further, to be used in the future. Firstly, by comparing it to the other non renewable energy sources (coal, oil and natural gas), nuclear power is a very clean energy as it does not produce any of the greenhouse gases such as carbon dioxide, which lead to the greenhouse effect or global warming. This problem is significant for the disintegration of the ozone layer when fossil fuels are burnt to release energy. Plus using this form of energy can save the reserves we have left of some of the precious fossils fuels like oil, which is said to run out within the next 50 years. Because nuclear power already supplies lots of energy, it is also much more reliable at present than many of the renewable options we have available such as wind, solar and wave. A very important point and something that must be considered is that there can be huge amount of energy produced from just a small amount of nuclear element. Just one kilogram of uranium can produce as much energy as 3,000,000 kilograms of coal. Finally, with the nuclear energy economy being one of the safest in the world, producing the cheapest energy, development in the future can provide thousands of jobs and other opportunities of stable employment for many people. Arguments AGAINST using and developing nuclear power As well as the very well argued points agreeing with the future use of nuclear energy, there is opposition to this expansion. There are many people and often groups that raise concerns about the safety of nuclear power. Nuclear waste that is produced from the nuclear power stations emits a very high amount of dangerous radiation that can stay radioactive for up to 25,000 years so it must be disposed of very carefully. Any accident is extremely dangerous and can kill any life in the surrounding area immediately. A case study that shows the extreme risk of development of nuclear power and what can happen if an accident occurs is the 1986 incident in Chernobyl, Russia. Here a nuclear reactor exploded killing 31 people, and around 140,000 people were evacuated as quickly as possible. This area around the explosion was contaminated by radiation and this will remain for a long period of time. The clouds of radioactive material that were also released by the explosion spread, reaching even as far as Sweden. The wind that blew from Chernobyl also came across to Britain and caused acid and other toxic rain that ruined farmland, making the soil radioactive. Farmers are still having problems in parts of Wales because of the radiation that has spread as a result of an accident at a nuclear power plant. Rather than looking at nuclear energys dangers, it also has a few faults. One of these are that a big part of the energy that is created must be blown away because it cannot be used. Nuclear power is also unable to adjust to a lower power production for night. These are faults which not only can cause problems but also inconvenience. Back to the issue of the nuclear waste, focusing away from its safety concerns, and more about where it can be disposed of without causing major problems. As it does stay radioactive for a very long time it must be discarded carefully. The pollution of this waste can cause serious effects on both people and the environment. An example of pollution has been in the Irish sea which was dreadfully polluted by the nuclear waste from the power plant at Sellafield in Cumbria. This fuel should ideally be stored in a safe environment either underground or in special concrete surrounded stainless steel liquid tanks. Another concern that is brought up with nuclear power is the potential for nuclear weapons to be developed. In these weapons would be uncontrolled nuclear fission where even if just a small amount of unstable uranium or plutonium is used, a bomb would explode. If more countries turned to the development of nuclear energy we could be at risk of production of these weapons by countries such those in the Middle East and terrorist groups, some believe it may even lead to a possible nuclear war in the future. Conclusion Looking at all of the arguments for and against the issue of whether nuclear power should be developed for future energy supplies, they are all valid reason that should be taken into account. As for my personal response, I feel that nuclear energy should not be developed as the building of more power plants could cause harmful effects, especially if accidents occur. I feel that the chance of accidents taking place are far more likely if this source of energy is developed. This can lead to the deaths of many lives due to the sheer amount of radiation. Plus looking at the locations of nuclear power plants in the UK, they are mainly in remote areas, for obvious reasons, and also near the sea. More of these can lead to their expansion in more populated areas putting many lives in danger. I also feel that instead of turning to another non renewable energy from fossil fuels, it is far better to invest and research into the development of renewable sources which will give us clean, cheap energy in the future. By looking at changing the technology for these alternatives now, we can help plan for the future. However, if the nuclear industry was developed then when reserves of uranium and plutonium ran out we would once again be searching for other ways. So overall I feel that nuclear energy, although cheap and reliable, is not the best option to be developed for future use, not just in this country but around the world.

Essay --
I, Alexander III, was born the son of a great warrior, King Phillip II of Macedonia and a Olympiaââ¬â¢s, daughter of King Neoptolemus I of Epirus. I was born on the 20th day of July in the year 356 BC in Pella Greece. I spend most of my childhood in Pellaââ¬â¢s royal court. I hardly ever saw my father because he spend most of his time in military campaigns or with one of his may other women, besides my mother. On the other hand, mother, was always there for me, even when I did not ask for her presence. From a young age mother and father wanted the best for me, even if I times I didnââ¬â¢t see it. Both my parents influence me to become what I am today. To them my education was extremely important. First, Leonidas tutored me; he was a very stern man. Of course, me being the free spirited young lad that I was might have contributed to the way he treated me, non-the-less. I do have to admit that Leonidas did help develop my physical endurance; his harsh schooling was the foundation for my physical hardiness and endurance. My father was not completely satisfied with Leonidasââ¬â¢s ways, so he saw to it that I would no longer be taught by force but rather by persuasion. Consequently, at the age of 13, in the year 342, Aristotle was assigned control over my education. He was a master of science and my father thought he would be the best for me. Indeed it was one of the best decision my father made for me, being that he hardly had time for me. With Aristotle my passionate love of Greek culture came to be; he made me entirely Greek in intellect. Aristotle was an inspiration for me then and continues to be now as I write this. Being around all these extremely intelligent individuals and hearing stories about the victories that great military general acc... ...h my father and Alexander. As Alexander and I took our seats and allowed my father to walk to his throne to sit, Pausanias rushed upon him and drove a blade between his ribs. My father dropped dead and Pausanias was killed while trying to escape. After this I was rushed to the palace and declared king. As delighted as I was I could not forget what had just happened. How could Pausanias, my fatherââ¬â¢s chief bodyguard and friend do this? Within a matter of seconds I understood what had occurred. Mother had encouraged Pausanias to commit this horrendous crime. My mother had accomplished what she set out to do, she had killed King Phillip II and made me King Alexander III. Later, she confessed to me all she had done, as king I could have had her executed, but I could not do such I thing. I loved my mother and she did it for my benefit. Iââ¬â¢ve kept her secret till this day.
Genesis, the Education of Abraham Essay -- Holy Bible Genesis Essays
Disillusioned Latin students, who cringe at the thought of repeatedly scribbling their grammar, are often told by their teachers, "Per repitio nos studiare," which translates to "through repetition we learn." Though this may seem hard to believe as their hands begin to cramp, it bears a certain amount of truth. As my grandfather once told me, "Experience is often the best teacher." Truly gaining an understanding of something often comes from repeated involvement. Repetition is also the concept that the Hebrew Creator-God uses throughout the story of Genesis to educate Abram about God's purpose and His nature. God is aware of the doubtful and cynical nature of Abram. Over time, God uses Abram's own repeated mistakes to build a conceptual understanding of Himself for Abram. This model provides Abram with a relevance for God in Abram's own life. Though the classic view depicts the patriarch Abraham as blindly, obedient, there is significant evidence within the story of Abraham to show that he was not so naturally submissive. The text often depicts Abram as doubtful, indignant, and sarcastic to a fault. Taking this side of the text in context illustrates Abraham as the antagonist in a battle against God. In this struggle with God, Abraham achieves excellence by learning, through repetition of his own errors and the reinstatement of God's promise, that it is in his best interest not to fight against his own personal idea of God, but to recognize, respect, and accept the true will of God. The story of Abram begins when, at age 75, he is called by God to leave his home and all that is familiar to him. In return God promises: "I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shall be b... ...ith the Creator-God, but with his misconception of the relationship that must exist between himself and God. Through his repeated disrespect and misunderstanding of who God is Abraham learns about his faith, his God, and himself. Although it may seem trivial, there is a legitimacy in asking a Latin student to rewrite a 300 page grammar book 300 times. The legitimacy lies in the fact the student will learn the Latin, even though he may have a cramped hand. Much like the Latin students, Abraham learns the to recognize respect, and accept the will of God through a repetitious cycle that brings him a cramped ego. Surely he would agree with the Latin scholars when they say "Per repitio nos studiare." Work Cited The Holy Bible, King James Version. Cambridge Edition: 1769; King James Bible Online, 2015.

Environmental issues Essay
Nowadays, environmental issues are rapidly raising concerns and awareness to the society. It is good to know that problems involving environmental neglect and degradation are a problem of environmentalists no more, but also of politicians and ordinary citizens as well. Say, we should analyze a hypothetical problem regarding the issuance of business license in a local western coast, where two pre-dominant businesses already exist, a bait fish fishery of pilchards and an oyster lease. There are two promising businesses vying for the license, a Tuna Cage Farm and a Dolphin Swim Tourism Project. Both of the new establishments would create added benefits and disadvantages to the area and the pre-existing businesses, so the choice should be carefully examined. Primarily, the bait fishery in the western coast consists of pilchards. Pilchards are any of various small marine fishes especially the commercially important edible species. These pilchards are caught throughout the year, mostly during the night, using purse seine nets. The nets are pursed and drawn to an area adjacent to the vessel, and fish are removed from the net with pumps and placed in the hold of the boat. In laymanââ¬â¢s term, pilchards have a wild capture. Unlike the wild pilchard capture, the tuna harvest is spawned in floating cages. Since it is a controlled environment, the unutilized feed components in the cages usually accumulate in the ambient water columns and substantially alter the benthic environment for the fishes. The toxic wastes from tuna cages caused massive pilchard mortalities, as shown in 1995 and 1998 incidents. Furthermore, the toxic wastes spread far at a rapid pace, about 500 km in 20 days, as shown in graph. The Dolphin Swim project, on the other hand, would introduce more boats that might disrupt the spawning season of the pilchards. There is also a probability that dolphins would consider the pilchards as prey. But aside from that, the dolphins can co-exist peacefully with the pilchards. The benthic area is preserved and the probable food cycle is just a natural process. Moreover, the industry in the coast will be promoted. Comparatively, it is evidently more harmful to facilitate a tuna cage farm with a co-existing pilchard industry; thus, the Dolphin Swim project should be favored. The decision was based on two significant aspects; which business is economically efficient while remaining ecologically sustainable. The Dolphin Swim Industry fulfilled these criteria.
