Essays on Ethanol

There is a strong association between alcohol consumption and development of cancer. Data from 2009 suggested that alcohol consumption was responsible for approximately 3.5% of all cancer deaths in the US (Nelson et al., 2013). In addition, alcohol-associated cancers were responsible for 17.0 to 19.1 years of potential life lost for each death (Nelson et al., 2013). The chances of developing alcohol-related cancer are higher among persons with higher regular alcohol intake over time. Alcoholism might influence the development of cancer depending on the quantity of alcohol consumed and duration of that consumption. The risk of developing alcohol-related cancer ...

Energy is the most important aspect in modern world, as the dependency on energy is inseparable from people’s life. Furthermore, the needs to travel using automobiles create an insatiable need for fossil fuel to power the movements. Unfortunately, fossil fuel is a non-renewable resource that is estimated to be depleted in 2042 (Shafiee and Topal 181). From environmental point of view, fossil fuel combustion from diesel and gasoline vehicles has high contribution to the pollution level in urban areas (Chow and Watson 222). In addition to the pollution level, combustion of fossil fuel releases CO2 a greenhouse gas that contributes ...

Before the 16th century, the existence of micro-organism had not been discovered. It was until a microscope was invented that micro-organism become a subject of discussion (Barnett 2003). Microbiology is the study of microorganisms or microbes. Microorganisms are the smallest living organisms that cannot be observed with our naked hence they need to be magnified using magnification tools such as microscope. Examples of micro-organisms are bacteria, virus and fungi. Fermentation in simple terms is the conversion of sugar into acid, gases and alcohol by enzymes that act as catalysts (Pumphrey and Julie 1996). Fermentation is a process that occur takes place in ...

Question 1: The Rise of Japanese Democracy

Japan stands out as one of the nations that have a thriving democracy in the East Asia. Just before the end of the Second World War II, Japan was only a formative democracy just like it is the case with most Middle East countries at the moment. However, following the writing of a new constitution in the year 1947, Japan transformed into a constitutional democracy. The building of democracy in Japan has been achieved through a combination of factors. First, Japan is an ethnically heterogeneous nation which enables for accommodation of other people’s views, a key facet of democracy. The country boasts of a rich ...

Introduction

Arguably, entrepreneurs are always risk takers, and will always go for any opportunity that is capable of making profit. There are various entrepreneurial issues that surround the oil and ethanol made from cellulose in the United States. The EPA is fining companies yet the product does not exist. As a matter of fact, there is a lack of supply of the products in question, yet the entrepreneurs do not jump for this business. There are various reasons for this entrepreneurial behavior on the issue. One of the reason is that despite the lack of supply, there is no single sell of ...

The question “why countries that do not have that much natural resources to boast of often appear more progressive and financially stable than countries that are staggeringly abundant in natural resources?” has been common among citizens of both resource-rich and non-resource-rich countries for a very long time. It is actually logical to think that a country rich in natural resources, especially the point-source and non-renewable ones such as oil, diamonds, and other ores, would outperform those that are less blessed because they already have an edge to begin with. However, according to Sachs & Warner (2001), the opposite happens. Sachs ...

1. Compare and contrast organic, inorganic and solid phase approaches for DNA isolation

Organic isolation takes place after the DNA has been released from the cell and a further purification is to be conducted. The purification is done in order to remove the contaminating proteins, lipids, carbohydrates and cell debris. Organic isolation makes use of a combination of high salt, low pH and an organic mixture of phenol and chloroform. The mixture dissolves hydrophobic contaminants and then strips away most of the DNA associated proteins. The DNA precipitate in this method is collected by centrifugation. The DNA pellet is then dissolved in rehydration buffer. Inorganic isolation method is used in cases that do not ...

Introduction

The United States of America is one of the leading countries where fossil fuels such as coal, oil, and natural gas are used to satisfy more or less 80% of the energy needs. Fossil fuels are utilized extensively for heating homes, running vehicles, providing power to the industrial sector, and for other significant purposes, especially the provision of electricity. However, it is also not an untold secret that the fossil fuels will eventually reduce considering the known reserves of the mentioned fossil fuels. It is also apparent that there has been a considerable increase in the costs related to the ...

Abstract

This experiment involved alkene preparation by alcohol dehydration (water elimination) in the presence of an acid catalyst. Elimination, combination, rearrangement and substitution are the basic types of chemical reactions known in organic chemistry. Alcohol dehydration is an important transformation that leads to the yield of alkene and it is an example of an elimination reaction. Dehydration is a process that involves the elimination reaction of an alcohol. There is a loss of H from one carbon and OH from adjacent carbon, hence, resulting in a water molecule removal that results in the formation of alkyne or alkene. When an alcohol loses its ...

E85 is a fuel form that contains 85% ethanol and 15% gasoline. Ethanol is a renewable fuel derived from organic matter through fermentation. In the United States, ethanol is produced from plants such as corn, grasses, and sugarcane (Ethanol par. 1). Ethanol blended fuels such as E85 are deemed desirable as they reduce overdependence on fossil fuels and lower greenhouse emissions from vehicles. The economy has been receptive to blended fuels as consumption rose from 1.7 to 13.2 billion gallons between 2001 and 2013. However, ethanol use is contentious because the fuel can only be used in flexible-fuel cars. Also, ethanol ...

Abstract

All cells in a living organism require energy to drive various cellular activities such as transport of molecules and movement among others. The rate of cellular respiration may be affected by the substrate concentration, pH level and enzyme concentration among other factors. This experiment aimed to study the rate of cellular respiration in isolated mitochondria under different conditions. It was hypothesized that if the concentration of the substrate is increased then there will be an increase in the rate of cellular respiration. Mitochondrial suspension was used as the source of succinate that was used as the substrate. The level of ...

Rajagopal, Deepak, and David Zilberman. (2011) Environmental, Economic and Policy Aspects of Biofuels. Hanover, MA: now. Print. The economic argument behind using of subsidies in the economy is probably to balance the interest draw by individual players in the market to a fair ground for all. The U.S. government use subsidies to reduce on the weight of production for the producers of products. This is done through tax subsidies or the government participating in production process to prevent consumer exploitation of producers. This has been the cause of disagreement in a tough argumentative debate as to whether it is appropriate ...

Essay

Abstract In today's fast moving constantly changing world every person might need some certain means for relaxation once in a while, thus, it will be very difficult to find a person who has never tasted alcohol in his life. Alcohol is one of the lightest forms of addictive substances, but still the danger of becoming addicted is huge, especially if drink alcoholic beverages on a usual basis. Of course it does not mean that our human body has any physical need for alcoholic beverages at all. This need, if appeared, is only psychological, that is why psychological programming is extremely popular ...

The extreme dependence of our present day civilization on Fossil Fuels is a matter of much debate. Coal, natural gas and oil accounted for 87 percent of the world's primary energy consumption, predominantly led by the US as the largest consumer of these fuels. (Cusick, 2013) The US leads the race in the use of these fuels with other emerging nations too vying for the spot. In the US, the recent discovery of shale gas has ensured that the US will continue to dominate the global scene in the usage of conventional fossil fuels. Further, the US has also seen a ...

It would be tough to choose between the positives and negatives of an electric car, because along with the number of positives it carries, it does have its share of negatives as well. However, going by the popular view that with gasoline depleting and carbon emission increasing, electric cars would be best suited for modern transport; the positives undoubtedly outnumber the negatives. As the world population grows, the need for housing and food has slowly by surely started eating into the forests, and man finds himself fighting for space with animals. As growth has to be supplemented by development, ...

There are four transitions of food production that cultures have utilized. The first is foraging where people hunt wild animals and gather plants. The second is pastoralism where people herd domesticated animals. The third is horticulture where people farm in small scales. The last is intensive agriculture where people also farm but in a larger scale (O’Neil). Each of these types uses at least one of the three main power sources of agricultural mechanization. The first is human power. The second is animal power, and the third is mechanical power. These mechanizations, especially the machineries from the third ...

Following the story of the use of ethanol to provide warmth in cold environments, this paper presents research on the effect the consumption of ethanol has on an individual’s body temperature. Firstly, the distribution of heat in the body is done by the blood. Through the vasodilatation and vasoconstriction of blood vessels, the body loses and retains head respectively. Given that ethanol enters the bloodstream directly upon consumption, its effects are almost immediate. Its presence in the blood causes the widening of blood vessels due to its vasodilation effect (Eston & Reily, 2013). This results in an increase ...

Introduction

All cells carry out cellular respiration in order to meet their energy requirements and to form metabolic intermediates that can be used to form secondary products. Amongst those products formed as a consequence of cellular respiration, are ATP and CO2. The formation of ATP in the cells occurs through the use of organic molecules available in the form of food (Lehninger, Nelson, & Cox, 2008). When oxygen is not available, ATP formation goes through a fermentation process, usually, referred to as alcoholic fermentation. The process utilizes a number of different sugars as the starting material. These sugars include fructose, glucose, and sucrose. The ...

Introduction

Esterification reactions refer to those processes between carboxylic acids and alcohols reacting together to produce esters (Smith, 2011). Ethyl ethanoate also referred to as ethyl acetate is one of the esters and is prepared through a reversible reaction between an alcohol and an acid. The process results in the production of an ester and water. The catalyst used in the reaction is sulfuric acid, which also works to remove water that is produced and thus to increase the yield of ester produced. The preparation of esters through this method is a good introduction of how equilibrium manipulation may help in increasing ...

Article Review

In this paper, I review the article Fundamentals of Beer and Hop Chemistry, authored by Keukeliere, D. (2010). In his article, Keukeliere (2010) begins by indicating that beer, an aqueous fermented drink, is based on starch, but flavored by hops. Keukelier (2010) notes that, barley, and most specifically barley malt, is the main body of beer. In order to produce one liter of beer, a few hundred grams of barley malt are needed. However, Keukeliere (2010) indicates that in the absence of barley malt, starch-rich adjuncts such as wheat, corn or rice can be used. Keukeliere (2010) notifies ...

Today most of the companies follow the principles of sustainable development and pay more attention to managing reputation and image assets and risks. This trend is caused by the establishment of a new type of competition between the companies: the companies compete neither in price nor in quality tactics, they compete in ideas and principles that come with this or another product. More and more people are paying attention to ethical aspects of the company’s operation (for example, in-life testing of products). This means that ethical and corporate social responsibility principles have become one of the driving forces of ...

After reading the Green Dreams article, the best biofuel is the cellulose-produced biofuel. This is primarily because the production is not dependent on food crops like other ethanol production processes that use corn, soybeans, or sugarcane. Accordingly, rather than use the kernels to produce ethanol, it is possible to use the cellulose that is found in corn plants. As such, cellulose-focused biofuel production does not compete with food crops. Accordingly, the production of ethanol using cellulose is safer because it reduces the rate of global warming considerably taking into consideration that it involves use of heat and acid then ...

Embryonic stem cell is a crucial factor in the developmental process of a multicellular organism. Embryonic stem cells (ESCs) are derived at early stages during development and eventually give rise to all type of tissues and organs in an animal. The ES cell lines have three properties consisting of self-renewal, primary chimera formation and pluripotency [1]. Pluripotency, a key feature of ESCs, refers to the capacity of a cell to differentiate into several different types of tissues [2]. An array of cellular factors play important role in maintaining pluripotency and determining cell fate in the developmental pathway. Negative effects on these factors may ...

Sugar was original derived from the French word “ Sukere” (oxford). By understand the power of sugar, as a commodity and industry, in relation with the current modern globalized market, one can better understand the impact this substance has had on both the present and in the past. I am convinced that sugar is a powerful force that has had a great impact on history. Sugar production has not only caused the physical colonization, its use has caused us to differentiate class identity around it; today we take for granted the presence on sugar around us. Examining both the social and economic ...

Introduction

Fermentation process refers to the conversion of sugars such as glucose to alcohol, carbon dioxide and energy in the form of ATP (Kale and Gokhale). Fermentation occurs in the absence of oxygen and converts substrates such as glucose into products such as acetate or lactic acid. During fermentation, there is no oxidation phosphorylation and thus the amount of ATP that is produced is low (Pigage, Neilsen and Greeder). One specific example of fermentation is lactic acid fermentation, which is the simplest form of fermentation. In the presence of oxygen in the cells, most organisms bypass fermentation to undergo cellular ...
