Cooking oil And Fuel for car use Essay Example for Free
Cooking oil And Fuel for car use Essay It is now commonly reported in the media news and conferences on climate, environmental degradation and global warming and many of these terms are pointing to the compounded nature of the environmental problems and the need for individuals and government to arise, proffer solution and rapidly intervene. The fossil fuels are the most polluting types of fuel to the environment. This is because it is widely used and produced . F is the reaction in the combustion gas that involves carbon dioxide and carbon monoxide (CO, CO2), both of which contribute a large share to the phenomenon of global warming. This phenomenon has the potential to increase the level of water in the seas, oceans and poles due to the melting of ice and thus the sinking of large areas of the continents. There are many alternatives to fossil fuels that can provide the energy necessary for human life such as solar energy and hydrogen cells. However, all of these alternatives are either still under testing or expensive and this hinders their use in the present time. Another alternative that can be used at the present time due to the fact that it is accessible to all is the biodiesel. The biodiesel is derived from edible oils used in household cooking and it is formerly regarded as unfit for human use. In restaurants where the owners spend a lot of money to individuals who help them to get rid of these oil can now heave a sigh of relieve in that they can now turn them into fuel suitable for the operation of motor vehicles, generators, motorcycles and any machine that utilizes internal combustion . The biodiesel (Biodiesel) is twice as clean as fossil diesel chemical composition has a smaller number of carbon atoms. Therefore, they produce less carbon exhaust, which is also the highest for the regular diesel, and by this, the lifespan of the machine is maintained and the biodiesel is conserved. Biodiesel is therefore safer than the regular diesel. It burns at 167 à ° while the regular diesel on the other hand burns at 70 à ° Celsius. The modus operandi of biodiesel Introduction The basic idea in the production of biodiesel is from used oil preferably from soybean oil. However, in the absence of soyabeans, any other type of vegetable oils can be used depending on the chemical composition. In the oil molecules, a break in the interaction is initiated by addition of alcohol in the form of methanol or ethanol with the presence of a catalytic sodium hydroxide or potassium hydroxide from glycerol (as output or product of interaction) along with ethyl esters (biodiesel). Methods Purification The action of this interaction in several stages and they are: 1)initial purification: Since the oil used has already been used in cooking, then it contains a residue that must be disposed of before the beginning of interaction and here a of silk oil passes through a large piece of primary filter Furthermore, it is heated by placing it on fire to refine the oil at a temperature between 60 à ° -70 à ° Celsius. 2) calculating the amount of the incentive: The catalytic factor is usually used in calculating the quantity of sodium hydroxide and this is one of the most important steps of the process This is because any increase or decrease in the quantity of sodium hydroxide would increase the proportion of outside interaction (Glycerol) at the expense of the required product (biodiesel). Variables/materials needed to calculate/obtain the amount of the incentive are -Methanol (these are at the centre of racing cars and can be found in stores that sell chemicals) Standard Boboli alcohol (Isopropyl Alcohol 99% IPA). -A scale is needed. -A measure of the acidity of the paper known as the PH obtained in some major pharmacies. -A standard pan. -Gloves and a protective cover to the body. Calibration factor is the amount of catalytic heating oil during the fire where it is in interaction with a separate calibration of the oil as highlighted below: Storage Mix 1 gram of sodium hydroxide with 100 million litre of water to obtain a solution of sodium hydroxide. Mix 1 billion litre of oil with 10 billion litre of alcohol Boboli. Qatar and the use of sodium hydroxide solution to fall on the oil and alcohol solution, and measure the acidity of the oil solution using paper (PH) . After the addition of every billion litre of sodium hydroxide solution, we will find that acidity has increased. This process continues until it reaches pH between 9-10, then count the number of litre of Millilitres of the signed dropper, and not litre. For example, 6 million litre and grams will be converted to 0. 006 grams of sodium hydroxide per 1 million litre of oil or 6 grams per 1000 billion litres of oil. Adding this to the 6 grams with 3. 5 grams taken as constant, a total of 9. 5 grams of sodium hydroxide per litre of oil is obtained. Add the calculated amount of sodium hydroxide in methanol to that of the whole interaction, away from oil, and half the quantity of methanol quantity of oil used the result of the interaction of sodium oxide and methanol (sodium methoxide). However, be careful as this is a highly toxic chemical compound, and must be kept away from direct skin contact. It has the potential to destroy the nervous system and therefore one must take all feasible precautions in the conduct of this interaction. Confused: Sodium oxide is added to methanol (sodium methoxide) and then to the oil through the suppression of stirring and then, heating continued for an hour. Sedimentation and Sedimentation After the completion of heating, the composite is placed in the settling tank for 24 hours in which there is separation of glycerol from biodiesel based on the principle of density difference. In order words, the more the dense glycerol deposit at the bottom and the remaining part settles at the top of the diesel. After the liquidation of reservoir sediments, there is separation to glycerol and diesel, and the difference can be seen easily through the density and viscosity, and if the difference is not obvious, the use of diesel is recommended in this case. To ensure that the use of diesel favoured, the density can be measured using hydrometer which is in stores that sell chemicals . Where reading between 0. 85 -0. 90 densities were not even, then Valdes is not fit for use. It can also be mixed with biodiesel fossil diesel by 40% to 60% which is vital if the fossil machine contains many parts of rubber. In conclusion, we have thus made a lot of benefits from the use of biodiesel. For instance, we have oil we use, and also we have the price of fuel reduced, and then we are able to maintain the machine, and diminish the emission of the environment. ââ¬Å"A diesel motor can also run on a fuel made from used and new vegetable oil called biodiesel (Microsoft Encarta, 2008) Reference El-Messidi, K (2007).

The Digital Conversion in Television Essay -- TV Digital Technology DT
The Digital Conversion in Television Introduction Television is now in the process of converting from analog to digital technology. The significance of this change is greater than the introduction of color TV in the 1960ââ¬â¢s, but more complicated since conversion will require new equipment for all consumers. Unlike color TV, digital television (DTV) uses a new kind of signal that does not fit within the structure of the old signal. "DTV" refers to a specific standard being implemented in the United States to carry a television signal in digital form through all stages of its transmission, not just for digital equipment such as video tape recorders and satellite receivers that have already been used in conjunction with analog television. The Federal Communications Commission (FCC) is the regulatory authority for the use of DTV. The Commission required TV stations in the top ten markets to begin broadcasting digital signals on separate channels along with their current analog signals. Stations in smaller markets are being phased in, and all commercial stations are expected to broadcast a digital signal by 2002. By 2003, all public stations are expected to go digital. The FCC will allow broadcasters to pull the plug on analog by 2006, although many people in the electronics and communications industries feel that analog TV may persist for a few years longer (Churchill). Digital television is being promoted for three distinct advantages: better picture, better sound, and more functions and flexibility. A digital picture has better color and is free from ghost images and snow. In addition, the DTV format allows for greater resolution than analog TV, a resolution high enough to be known as high definition television (HDTV). Th... ...re/0,1284,14770,00.html>.

Two Successful Business People Who Inspire Me
Two Successful Business People Who Inspire Me Success is something that we all aspire to. We cannot feel genuinely happy for long if we felt like a failure within. The most encouraging reality about success is that it is attainable to all irrespective of who we are what we are or where we are. Success also has a different meaning for each one of us. Success being a personal realization should logically be achievable by all, but we know that this is not really so. Most of us are unable to accomplish what we really want to do or what we really work for.When we struggle for success and do not achieve it. We become frustrated and this leads us further from our goal. This is what has inspired me to study and write about this complex subject. Achieving success is right and can realize it with the ease it provides you to go about the right way, you just have to know the rules and apply them in your life. Bill Gates was born on Oct 28th, 1955 and he is an American business magnate, philanthr opist and chairman of Microsoft. The software company he founded with Paul Allen. He is consistently ranked among the worldââ¬â¢s wealthiest people.During his career at Microsoft. Gates held the position of CEO and chief software architect and remains the largest individual shareholder. He has also authored or co- authored several books. Gates is one of the best- know entrepreneurs of the personal computer revolution. In the later stages of his career. Gates has pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through the Bill and Melinda Gates Foundation in 2000. At Harvard, he met Paul Allen, who became Gatesââ¬â¢ close friend.They got obsessed with the computers that they were late for some of their classes. They even skipper some classes to be in the computer lab. Unfortunately, their computer time finishes after spring. However, they did not graduate in the Harvard. Allen and Gates had to leave to devote their energy full-time and thriving company. They had a belief that the personal computer would be a valuable tool on every office desktop in every home. Gates and Allen began developing software for personal computers. They collaborated together to make the language BASIC in the first Microcomputer, and in 1975, they started the Microsoft Company.Warren Buffet is the worldââ¬â¢s most successful investor and self-made billionaire. He is consistently ranked among the worldââ¬â¢s Top 3 wealthiest people. Buffet runs and owns about 31% of Berkshire Hathway, a 136 billion investment company that has substantial stakes in Coca Cola, Wells Fargo and American Express. A 1 dollar investment in Berkshire in 1965 would bring about 5000 dollars in 2005. Since 1951, Buffet has generated an average annual return of about 31%. The average annual return of the Standard Poorââ¬â¢s 500 stock over that period is 11%.Warren Buffet was once asked what is the most i mportant thing he looks for when evaluating a company to invest in, without hesitation he replied ââ¬Å"sustainable competitive advantage. â⬠Indeed, while business valuation matters. ââ¬Å"it is the future growth and prosperity of the company underlying a stock, not it is a current price, that is most important. A companyââ¬â¢s prosperity in turn is driven by how powerful and enduring it is competitive advantage are. Sustainable competitive advantage and marked category leadership give a company the edge that keeps competitors at bay and reap extraordinary growth and profits.Warren Buffet seeks to identify rare companies with strong competitive advantage that has a potential to grow even stronger over time, when a company is able to achieve this, it is investors can be rewarded to decades. Obviously, we can draw the conclusion that both of buffet and Gates influence to me is far from my imagination. Beside stocks, ideas, and investment, I learn many aspects from them, the ir team spirit and their friendship with partner. I hope there will be more and more people like them, who are not only successful, but also influencing other people.
