Economical and Environmental Cost-Benefit Analysis on Hybrid Cars Essay Example for Free

Economical and Environmental Cost-Benefit Analysis on Hybrid Cars Essay A hybrid car is a car propelled by the application of two or more power sources. First attempts to introduce hybrid cars goes back to mid 1660, way before the discovery and introduction of the fuel powered conventional cars but were never commercially manufactured until 21st century when Japanese car manufacturer, Toyota produced the Toyota prius exclusively for its domestic market. In fact, it is estimated that the first attempt to produce a hybrid car was in 1665. The delay in the production of this class of vehicles was because of two main reasons; first, the limited range in the distance the vehicles could cover and secondly the difficulty and costly process of recharging their batteries. Furthermore, it is a basic science concept that the more complex a machine is the more it is prone to failure and thus the idea of commercial production of hybrid vehicles has been a slow process over the centuries. World’s population explosion, demand for fresh air and green cities, dwindling petroleum deposits, over dependency in overseas oil, economic recession and global warming are just some of the environmental and economic factors that have forced world’s leading car manufacturers to provide to the market car models that are not only environmentally friendly but also cost effective. A cost-benefit analysis on this topic will attempt to bring out the cost of getting a hybrid car into the road in comparison to the benefits that the world stands to reap as a result of this venture. This research seeks to bring to the surface three major aspects that are associated with the introduction of hybrid cars into the transportation world. These three issues are: (i) The cost of producing a hybrid car: The successful landing of a hybrid car is in focus under this area. It is not easy to get into the road a car that makes use of a combination of two or more sources of energy. The research involved is estimated to run to millions of dollars thus sky-rocketing the price of a hybrid car. (ii) Environmental factors: Environmental factors simply refer to the concerns that a particular type of car produces substances that injure our surroundings thus making life on earth more dangerous and therefore more complex. These substances include green house gases as well as toxic metal compounds such as the ones that contain lead in their structure. (iii) Economic cost benefit factors: Economic factors have much to do with the living standards of people as far as the generation and investment of money is concerned. The economic make up of the world has gotten pegged heavily on oil and there are concerns from every right thinking citizen of the world that this is a self consuming trend that is likely to create serious economic problems if the oil industry hits a serious problem. This has already been witnessed before whereby a slight rise in oil prices has sent shockwaves in economies in both the developed and the developing world. Literature Review The former Vice President of the United States who later won the Democratic Party nomination and lost the presidency in a controversial manner to George W Bush, Mr. Al Gore, has had the world rethinking its actions as far as the degeneration of the environment is concerned. An inconvenient Truth, a film he worked on captures the problems that are already being experienced in various parts of the world as a result of global warming. This, he says is being fuelled by the use of environmentally unfriendly cars that use oil or gasoline (Gore, 2006, para1-3). It is not surprising that he went a head to win a Nobel Prize for this peace of work. Electric and hybrid cars have always received much appreciation due to the perceived ability to tackle this burning issue of climate change. Their ability to cut the emission of these toxic substances into the atmosphere that lead to negative climatic shift is the major reason for this (Anderson and Anderson, 2004, pp 6-10). In recognition of this serious problem, vital steps have been made in the research that is involved in the development and production of cars that make use of a combination of two or three sources of locomotive energy. Chief among these is the research into electric cars that promise to reduce the overreliance on oil (Westbrook, 2001, pp 34-39). The pioneer nation in the world in the research and possible mass production of hybrid cars is Japan. But the appetite with which the United States of America has picked up the issue points to the significance of this type of car. The driving force is the reduction in pollution, the saving that comes in terms of finances and most importantly national security that is put at risk with too much dependency on foreign oil. The argument is often projected in terms of supplying their dollars to nations that fund terror groups such as al Qaeda (Boschert, 2006 pp 2-7). It is common knowledge that mass production of hybrid cars will not only provide a partial solution to world environmental problems but also be a practical measure to save countries from losses running to millions of dollars due to escalating prices of world crude oil. The cost of producing a hybrid car The production of hybrid cars is not a cheap or a simple venture. Confessions by companies that have dipped their fingers into this hot pot have clearly shown that more than just simple technology is in play in the production of this type of cars. Research that has been on-going for a long time now is very complicated and has consumed millions of dollars. At the end of the day, despite the hyped advantages of shifting from purely oil consuming cars to hybrid cars, the cost that must be borne has to be high (Westbrook,2001,pp 56-61). It is the overall ability of the hybrid car to assist man in solving most of his economic and environmental problems that make the whole exercise worthwhile. Environmental factors While scientists agree that there can never be perfect environmentally friendly hybrid cars and that this depends solely on the design and model of hybrid power system. It is worthy appreciating that the use of this class of vehicles will automatically lead to the reduction of global warming by approximately 0. 3 to 0. 5 percent and that more advanced models and designs in the coming years due to technological advances would reduce this figure even further. The problems of the quality of urban air, reduction of noise due to application of electric motor in fuel power conventional cars, and elimination of smog forming pollutants could be solved in a century if research on mass production of hybrid cars is given a priority. The main source of air pollutants in cities and major towns is transportation. Fuel powered conventional motor vehicles produce much higher levels of carbon dioxide (Co2) carbon monoxide (Co), nitrogen oxides (Nox) and hydrocarbons (Hc) and this from the primary source of these dangerous pollutants. This is mainly because fuel powered conventional cars (FPCC) make short trips that do not give time for electric motor warm ups and cold starts. It is noted that hybrid cars reduced the levels of the carbon monoxide, hydrocarbons and carbon dioxide by 97% in comparison to other sources of these pollutants. Carbon monoxide (C0), when inhaled for long periods interferes with the proper functioning of the brain in that it impairs the flow of oxygen (O2) into the brain. Once the brain stops working in the expected way, the person involved turns into a vegetable. Carbon dioxide and water vapor form the principal components of green house gases that bring about the green house effect. Green house effect is a scenario in which too much heat is trapped within the atmosphere due to the presence of such toxic gases as carbon monoxide and this resultant effect is a highly raised earth temperature. Infact carbon dioxide (C02) is considered one of the major atmospheric pollutants, and is solely responsible for approximately 57% global warming. Negative effects of global warming include the rapidly declining numbers of polar bears and melting of ice in the tropics. It is therefore an open knowledge that releasing carbon dioxide (C02) into the atmosphere is detrimental to the lives of living organisms and the equilibrium of the ecosystem. Sulphur and chlorofluorocarbons (CFCs) are very dangerous air pollutants produced by combustion of sulphur containing fuels. Over the years, scientists have devised means of producing sulphur and lead free fuels but achieving an excellent degree is still a distant mirage. Deposition of these compounds in the air is harmful to plants, man and infrastructure. Exposure to high concentration of sulphur dioxide irritates respiratory tracts making breathing difficult and can easily cause lung problems. Sulfur Oxide contributes to respiratory illness. Patients suffering from heart diseases risk aggravating their conditions if exposed to even mild concentration of sulfur oxides. These components also form secondary pollutants when transported and combined with other elements forming sulphates, nitrate salts, nitrogen dioxides and even nitric acid vapor. This is what is commonly known as acid rain that corrodes buildings, burns vegetations, burns the human skin and destroys infrastructure. Chlorofluorocarbons also form component of green house gases that bring about the effect of global warming. When exposed to gamma rays, these compounds break down to release chlorine atoms. The presence of chlorine atoms in the atmosphere catalyses splitting of Ozone (O3) into oxygen gas (O2), however the negative effects of their presence overweigh their importance. Photochemical air pollution, usually known as smog and is commonly sported in the tropics and subtropics is also caused by incomplete combustion of gasoline emitted by fuel powered conventional vehicles. This process leads to the production of Ozone gas that is responsible for irritation in the eyes, extensive damage to plants and crops and lung complications. The release of carbon dioxide (C02), chlorofluorocarbons (CFC), sulphur oxides, nitrogen oxides (N0x) and other pollutants into the atmosphere contributes to the destruction of plants on the earth’s surface. Photosynthesis, the process through which trees produce oxygen from carbon dioxide is so vital to human life in fact it is said that life cannot exist without trees. Destruction of trees by releasing these pollutants into the air is equal to destruction of both human life and plant life. While particulate matters are the main contributors to lung problems and most cancer cases, hydrocarbons are also a cause of lung problems and other tissue problems. Long exposure to high concentrations of hydrocarbons eventually leads to total organ failures. Furthermore it is a major contributor to birth defects and other complicated illnesses like cancer. With the commercial manufacture and introduction of hybrid cars, extensive damage to the environment is definitely reduced, quality of life enhanced and urban areas become clean to inhabit, the dream of world environmental rights groups. Economic factors Crude oil is the raw material that propels almost all components of world’s economy in many ways. In fact the world is so dependent on crude oil that if its supply would be cut abruptly, major world economies like United States of America, Russia and China would immediately come to a standstill. United States depends on crude oil alone for 40% of its energy supply, triple than other sources. Overdependence on crude oil is not sound enough. First, crude oil is a non-renewable source of energy and analysts predict it will be largely exhausted within half a century. This rings an alarm bell that if measures are not put in place and countries go green by using hybrid cars, then the future is bleak and the word is in danger. Transportation sector depends entirely on oil for energy supply. Trucks, planes, ships cars and buses are propelled by motor engines that use oil. Introducing hybrid cars would reverse this trend, make the world safer from fluctuating oil prices and reduce dependence on this energy source (Paterson, 2007 para. 3-5). Reliance on crude oil for fuel supply is a major contributor to ethnic and tribal wars in Africa. This demonstrates the levels at which scramble for this commodity has reached. In fact notably China is so hungry for crude oil that it is ready to ignore the sufferings of millions of peoples around the world and specifically Sudan, so as to get its industry moving. It therefore points to the fact that lasting peace and safety will be found and armed conflicts reduced drastically when less fuel consuming cars are produced and thirst for oil curtailed. Hybrid cars are pocket friendly as they consume less gasoline in comparison to fuel powered conventional cars. Even though they are slightly expensive to purchase, the reward is achieved in long term due to lower fuel consumption. Further, governments and notably the United States of America give tax incentives to buyers of hybrid cars in to a move aimed at reducing the average prices of these vehicles and thus encouraging more people to purchase them. Dwindling petroleum deposits in a major concern to the world. It is widely acknowledged that only a total of one trillion barrels of recoverable crude oil reserves is available for exploration worldwide with only two percent (2%) of this value in the United States of America. Most of these oil deposits are found in the eastern hemisphere that is made up of countries that are well known for political instability. It is therefore very wise for countries that fall in the Western hemisphere and more so, the United States to adapt the mass production and commercial use of hybrid vehicles. This will not only cushion them from ever fluctuating oil prices but will also prevent the imminent collapse of most sectors of the economies of these countries. Conclusion From the foregoing, it is evident that the world stands to gain immensely from the introduction into the world of transportation hybrid cars. It is true that the cost of producing a hybrid car is not one that sends one smiling all the way to the bank. In fact it is prohibitively high and the faint hearted who will not pay attention to the long term benefits of this hybrid car model will not dare. But the benefits or gains both in terms of saving a planet in peril and a global economy in a shambles are so enticing and crucial that it is actually the way to go. The environmental problems that come as a result of oil utilization in transport and other areas of life will be dealt with once and for all. For instance, the release of dangerous gases such as carbon dioxide and carbon monoxide into the atmosphere that is responsible for global warming and numerous respiratory problems as well as problems in farming thorough such phenomena as acid rain will be solved. The economic woes that emanate from over dependence on oil will also be contained. The availing of financial resources to rogue nations such as Iran that fund terrorist groups, the shaking of the global economy due to shifts in oil prices as well as the escalation of conflicts in most third world countries in the east and Africa as a result of scrambling over oil resources will be eliminated.

Financial Analysis of Ryanair and British Airways

Financial Analysis of Ryanair and British Airways Financial analysis The purpose of financial analysis is to determine the financial health of a business. Generally, this analysis is performed by the professionals who prepare reports using the ratios taken from various financial reports. The financial ratios calculated are also helpful to compare with different business. The following analysis studies the four major financial positions of BA and Ryan air; Profitability, Efficiency, Liquidity and Financial gearing. Profitability: It is the primary goal for any business, without this the business cannot be projected in long run. The purpose of measuring profitability is the key contribution for success of business. The ratios which are used to evaluate profitability are listed below: Return on ordinary shareholders funds (ROSF) Return on capital employed (ROCE) Net profit margin Gross profit margin. ROSF: It compares the amount of profit for the period available to the owner’s average stake in the business during that same period. The ratio is expressed below: ROSF = (Net profit after taxation and preference dividend (if any) / ordinary share capital +reserves) Ãâ€" 100 The Ratios calculated for BA Ryan air are shown below: From the above table, it is clearly seen that BA values are inconsistent but whereas Ryan air tends to show improvement every year which gives more profits to the shareholders. From the definition we can say that the high ROSF %, the more profit available to shareholders. The year 2011 considered to be good for both airlines BA and Ryan air, since they are making huge profits and improved revenues compared to their previous year performance. As a result, their ROSF had risen to 26% 11.34% which resulting high profits to the shareholders. This scenario has changed completely when it comes to 2012 for BA. If their investors left their money in bank, they could have got some positive returns. But instead BA returned (3.6%) to their investors. Though its revenue is increased by 8% and operational cost by 11% it continued to show appreciable operating results. However, due to exceptional costs items like expense related to pensions, BMI’s acquisition affected the BA economy. On the other hand, Ryan air returned 16.11% which is higher than previous year to the shareholders. This is because Ryan air revenue increased by 25% and profit by 50% approximately compared to 2011. (According to annual report 2012).Though its operating costs are increased due to (fuel price rise) it managed to balance that by increasing passengers fares of about 15%. In 2013, BA has raised from loss of (3.6) % to 10.78%. This is because of company attains the profit from exceptional items ( £57m) and IAG part of BA contributed  £ (265m) and also revenue rose by 5.5%. Though inconsistent in fuel prices affects their operational costs which is almost 0.3% of their total operational costs. But BA managed to stabilise it by non-fuel costs which has risen in 2012. Whereas Ryan air revenue increased by 13% which is less compared to 2012 change. Since it’s a low cost carrier it should maintain passenger fare as low as possible in order to compete with its rivals but, inconsistency in fuel prices had raised their operational costs by 45% and passenger fare by 6%. At the end company operated in profits and returned 17.35% to the shareholders. Based on ROSF results, we can say that Ryan air has performed well continuously in three consecutive year’s period by giving profits to its shareholders but BA shown some ups and downs in its results. Further ratios will give us more idea why the difference has been evolved in their performance. ROCE (Return on capital employed): It is a fundamental measure of business performance. ROCE is defined as the ratio of net operating profit to the capital employed. Capital employed is the difference b/w total assets and current liabilities. The ratio is expressed below: ROCE = (NET PROFIT BEFORE TAX / CAPITAL EMPLOYED) Ãâ€" 100 The ratios calculated for BA and Ryan air is shown below: The above table describes the ROCE of a company for a period 2011-2013. From the definition we can state that higher the value of ROSE is indicating that the company c generates more earnings per dollar of capital employed. It enables us to analyse and compare BA and Ryan air without the impact of tax. It also considered the long-term debt as a part of capital, which is not the case of ROSF.Thus; this ratio reveals how BA and Ryan air economized on its overall capital. In 2011, BA performed well by giving a positive result due to increased revenue in 2011 from premium travel passengers. But the performance is shrined in 2012 due to rise in operational costs and loss of  £ 41m on exceptional items and also  £66m due to partnership with IAG. Due to this it had shown negative result in 2012. But in 2013, it again rises to 4.11% from (1.86%) because of the factors explained in ROSF. Ryan air has shown continuous improvement for three years. In 2011 its profit increased by 26% and carefully balancing the fuel costs and operating costs. For the other two years also it continuous to shown good result even though operating cost rise to 45%. Thus, we can say from ROCE ratios Ryan air performed much better than BA. The gross-profit margin is studied below to measure the profitability. GROSS PROFIT MARGIN: It is a key financial factor that asses the profitability of a company core activities excluding fixed cost. Gross profit represents the difference b/w sales revenue and the cost of sales. The ratio is represented by gross profit to the sales revenue generated for the same period. It is a given by the formula shown below: Gross profit margin = (gross profit/sales revenue) Ãâ€" 100 Gross profit margin ratios of BA and Ryan air is shown below: It can be seen from above table that Ryan air performed well compared to BA. Though the values over three years slightly fluctuate but they were generating good profitability by improving their sales and proper balancing and control of fuel costs which has almost rise to 38% in 2013. Similarly airport charges and other operational costs were stabilised to make airline in profitable condition. On other hand, BA also performed well except for the year 2012.in which its fuel costs rise by 14 %, maintenance by 15% and operating lease costs by 34%. Due to this they showed lower values. But by gaining proper control over the above costs mentioned they started to improve their profitability by 2013. Now net profit margin is studied in order to see whether the airline is able to improve its profitability. NET PROFIT MARGIN: It is the defined as the ratio b/w net profit before tax to the sales revenue. It also measures how much each of dollar earned by the company is translated into profits. If the value is low it indicates low margin of safety and higher risk that the sales decline will erase profits and lead to net loss. It is given by the formula as shown below: Net profit margin = (profit before tax / sales revenue) Ãâ€" 100 Net profit margin ratios for BA and Ryan air shown below: The above table depicts us Ryan air is operating much better than BA. From annual reports it is known that BA invested much money for long-term asset. Hence, their net profit margins are quite low in these three years. In 2011, it invested in IAG, bought BMI at  £172.5m in 2012 and from 2011 it’s investing  £5 billion every year for new fleet and up gradation of fleet and other.in 2011 it opened T5 which will be home to A380 fleet from 2013. On the other hand, Ryan air net profit margins are high since its investments for long term assets are low compared to BA. Ryan air continuously invest to buy new a/c’s hence it’s the reason that it has youngest fleet of planes in the world. In 2013 it decided to buy 175 new Boeing 737-800 a/c which will be a long term asset for the Ryan air to transport more no. of passengers. In conclusion to the analysis of BA and Ryan air, profitability is measured by using various ratios. The results are fluctuated for BA whereas Ryan air tends to show improvement year by year from 2011-13. Both BA and Ryan air increased their revenues, gained some control over operational costs along the analysis and deliver positive returns except for the year 2012 for BA. EFFICIENCY: The efficiency ratios measure the efficiency in which various resources are managed and used in the business. The following ratios are used to evaluate the efficiency of the business: Average settlement period for receivables Average settlement period for payables Sales revenue to capital employed Sales revenue per employee Average settlement period for Receivables: A business will usually be concerned with how long it takes for customers to pay the amounts owing. The efficient and timely collection of customer debts is a vital part of cash flow management. So this is the ratio which is very closely watched in many businesses. It is given by the formula as shown below: Avg.settlement period for receivables = (Trade receivables/sales revenue) Ãâ€"365. The ratios calculated for BA and Ryan air shown below table: The values in above table depict the average number of days used to collect its revenue from debtors. Both BA and Ryan air has got appreciable shorter period to collect their revenue. In the analysis period from 2011- 13, BA managed to get back his revenue from receivables by an average of 17 days with slightly increased in 2013 compared to 2011. When it comes to Ryan air it has got very shorter period of an average of 5 days. From the table it is clearly seen that debtor days have fallen which means business is converting credit sales into cash much quicker than BA. This shorter period certainly asset for Ryan air liquidity. Average settlement period for payables: The average settlement period for payables measures how long, on average, the business takes to pay its trade payables. The ratio is calculated by a formula shown below: Average settlement period for payables = (trade payables/credit purchases) Ãâ€"365 The ratios calculated for creditors as shown below: Sales revenue to capital employed: This ratio examines how effectively the assets of the business are being used to generate sales revenue. Greater the value represents higher productivity. The ratio is calculated by a formula shown below: Sales revenue to capital employed= (sales revenue/ (total assets-current liabilities)) The ratios are calculated for BA and Ryan air as shown below: From the table it is clearly seen that both BA and Ryan air have utilised their assets properly to improve their productivity and hence it is the reason their values of productivity rising over past three years. The values of Ryan air is small compared to BA because Ryan air revenue is almost half of BA’s total revenue. At last despite of their company size both are making use of their assets properly. Sales revenue per employee: It is the ratio relates sale revenue generated to a particular business resource, which is labour. Higher the value indicates greater staff efficiency. Its ratio is calculated by a formula shown below: Sales revenue per employee = (sales revenue / number of employees) The ratio calculated for BA and Ryan air shown below: The above tables describes about sales revenue per employee. Both companies uses different currency so for better analysis BA revenue is converted to euros according to exchange rate in that periods. The values clearly states that Ryan air is more labour productive than BA and other fact is noticed from table is that two companies increasing their efficiency over the analysis period 2011-2013. LIQUIDITY: These ratios are concerned with the ability of the business to meet its short-term financial obligations. Higher the ratio, the more liquid the business is considered to be, since liquidity is vital to the survival of a business. Liquidity is measured by the following ratios shown below: Current ratio; Acid test ratio. Current ratio: It is defined as the ratio b/w liquid assets to the current liabilities. A higher current ratio is preferable to a normal one since liquidity is vital part in business. It is given by the formula as shown: Current Ratio = (current assets/ current liabilities) The current ratio values for BA and Ryan air shown below: Values in above table clearly depict that BA current ratio values over three years On the other hand, Ryan air maintained its current ratio values >1 throughout analysis period in which it properly balanced short-term assets over liabilities and has got more liquidity compared to BA. In 2013 Ryan air current ratio value is decreased compared to 2012 because it has decided to buy 175 new Boeing 737 planes over next five years. Overall, Ryan air liquidity is better than BA. Acid-test ratio: This is an indicator that determines whether a company has enough short-term assets to cover immediate liabilities without selling inventory. This ratio is more reliable compared to current ratio because it doesn’t include inventory. This is given by a formula as shown below: Acid-test ratio=current assets / current liabilities. (Excludes inventories in current assets) The values for BA and Ryan are shown below: From the table it is seen that BA values during analysis period is 1.so, this ratio indicates that company experiencing good growth, fastly converting receivables into cash and also it can also overcome its financial obligations without depending on inventories. In conclusion to the analysis of BA and Ryan air, liquidity is measured by using various ratios. The results are fluctuated for BA whereas Ryan air tends to show improvement year by year from 2011-13. Ryan air has got more liquidity compared to BA and it can easily overcome its financial obligations. 3.4 Financial Gearing: It is the relationship b/w the contribution to financing made by the owners of the business and the amount contributed by others in form of loans. A business level of gearing is an important factor accessing risk. Gearing takes place of owner’s insufficient funds. Any business borrowing money from others agrees to pay interests; if the borrowing is heavy then this can be significant financial burden to the company. The ratios used to measure gearing are shown below: Gearing ratio; Interest cover ratio. Gearing ratio: It is defined as ratio b/w long-term lenders to the long-term capital structure of a business. It is given by a formula as shown: Gearing ratio = (non-current liabilities/capital employed) The gearing ratios for BA and Ryan air calculated below: The values from table states that both companies are highly geared businesses since their gearing ratios > 50%. Both the companies have high shares of long-term debt in their long-term capital structure. So both companies are subjected to financial risk. Ryan air tends to decrease its debts during analysed period which can be seen from the table by controlling their operational costs effectively during analysed period. Whereas, BA managed to decrease their debts with some fluctuations in values which can be observed from the years 2011-2013.so, a cash flow which is strong and reliable can handle high gearing effectively compared to cash flow which is unreliable .

Developing Low Energy and Sustainable Homes

Developing Low Energy and Sustainable Homes Climate change and energy security are the greatest challenges facing the world today. Climate change is causing global warming, which is the increase in the average temperature on the earths surface, air and oceans. The release of greenhouse gas emissions into our atmosphere, from human activities, such as burning fossil fuels and deforestation have been a major factor in their increase over the last 100 years. Energy security is vital for any developed economy. The OPEC member countries control about 75% of the worlds oil reserves (R). Many of these countries are politically unstable and they can control the price of oil. In the early years of this decade, the UK was a net exporter of gas and it is estimated that by 2020, they will only be able to meet about 40% of their oil and gas needs themselves(R). The UK needs to reduce its green house gas emissions and meet their energy demands without having to rely on other nations. The Kyoto protocol was established to limit and reduce the amount of green house gases released into the atmosphere. Industrialised countries, and those is transition to a market economy, which were called the Annex I countries have agreed to ratify the agreement and reduce their emissions to a 1990s baseline (R). The UKs commitment under the protocol is to reduce their green house gas emissions by 12.5% of 1990 levels, by 2008-2012. This involves an 8% reduction in their C02 emissions, the main cause of global warming, over this time frame. Further aspirational targets are set out in the DTI Energy White Paper published in 2003, such as to reduce CO2 emissions by 80% by 2050 (R). In 2002, the residential sector caused 27% of the UKs CO2 emissions, of which 82% of the energy was for space and water heating (R). The proposals, as laid out by Gordon Brown in 2006 stated that within ten years, every new home will be a zero-carbon home. The Code for Sustainable Homes was introduced in 2007, the code rates the sustainability of homes over six levels based on certain criteria. In theory, constructing zero-carbon homes (homes which can generate their own electrical and heating needs either onsite or locally) is a fantastic idea which will eventually lower energy demands and then lower the CO2 emissions countrywide. But they are ambitious plans and there are several issues that need to be resolved such as: Zero-Carbon Home: Definition New Construction Techniques Building Regulations The Code for Sustainable Homes Planning Laws Grants and incentives Whats happening now? Certifying Agencies Zero Carbon Homes: There is still some confusion as to the detailed description of a zero-carbon home. The Housing Minister, John Healy published on the Communities and Local Government (CLG) website the zero carbon homes definition: A zero carbon home is one whose net carbon dioxide emissions, taking account of emissions associated with all energy use in the home, is equal to zero or negative across the year. The definition of energy use will cover both energy uses currently regulated by the Building Regulations and other energy used in the home. (R) Detailed information is still needed about energy imported and used in the zero carbon homes. The energy standards state that there has to be onsite renewable energy and a locally connected heat supply to achieve a 70% reduction in the carbon emissions from current levels. Currently there is no allowance made for renewable energy generated off site, for example, wind and wave power. If I design a proposed zero carbon home and connect it to an energy company that is generating electricity in the north of Scotland, I might not achieve the rating I want which is unfair, even though he electricity is generated from a renewable source. The life cycle of a building is not taken into account in the definition of a zero carbon homes either. The construction, renovation and disposal can cause significant amounts of CO2 emission to be released. A life cycle analyses of a zero carbon home should include the embodied energy within the materials and waste disposal. Of course, not all of the material could be sourced locally as this would be impossible, but each council/local government should be able to compile a list of materials that are located locally. Ideally, a certain percentage of the local materials should have to be used. This would not only decrease the embodied energy within some of the construction materials but also help support local businesses. The government should invest more in the research of this idea, with many businesses suffering in the current economic climate, we should be buying locally, not importing. New Construction Techniques Building Regulations: Our European neighbours have been developing low energy houses and energy saving construction techniques for over 30 years. While some of the techniques might be new to the UK, they have been tried and tested on the continent. Currently the averaged U-Value for Walls, Roofs and Floors (wm2K) in Part L of the Building Regulations for the UK is 0.24, whereas in Germany and Switzerland the Passivehaus and Minergie-P regulations are achieving an average of 0.10(R). In 2013 the averaged UK Part L will lower to 0.18 and then in 2016 to 0.14. (R) The German designed Passivhaus has been a hugely successful energy saving concept that has only reached the UK in recent years. The basic principle include very good levels of insulation with minimal thermal bridging, utilising solar and internal gains by house orientation, window design and location, excellent levels of air tightness and good indoor air quality provided by whole house mechanical ventilation system with highly efficient heat recovery.(R) Sweden, also has produced energy efficient house designs since the 1970s, with different mandatory standards for the north and south due to the difference in climate. There performance standards are among the highest energy efficiency requirements in the world, already in line with Passivhaus standards. Over 7000 home have been constructed across Europe to the Passivhaus standard, the techniques used can easily be adapted here within the UK. The highly insulated and airtight passivhaus have a heating requirment of 15kwh/m2/year, which is nearly 90% less energy used to heat a standard UK home (R). These homes often need little or no heating for 9 months of the year. This will not automatically mean that the houses will achieve the highest level on the Code for Sustainable Homes. If we are to achieve the standards of the Passivhaus, the design and construction techniques should be introduced into the university courses now, for such degrees as I studied (Architectural Technology). These techniques are the future for zero carbon residential, commercial and industrial building. Starting with the basic house construction, if we are thought the techniques on how to construct dwellings that minimise their heat and hot water demand, less energy is needed, and expensive renewable options such as PV cells, geothermal pumps and domestic wind turbines can be reduced. We can then adapt these techniques for other building types. Code for Sustainable Homes Sullivan Report: The Code for Sustainable Homes (CSH) was introduced in England on a voluntary basis in May 2007 and a code rating for all new buildings became mandatory from 1st May 2008. The Code Level 3 rating for newly constructed homes promoted or supported by the Welsh Assembly Government became mandatory from 1st May 2008 also and from 2nd June 2008, Code Level 3 is required for all new self-contained social housing in Northern Ireland (R). The Code does not apply in Scotland. A panel was appointed by the Minister for Transport, Infrastructure and Climate Changet, chaired by Lynne Sullivan, they made recommendations to develop a strategy to achieve zero net carbon emissions. Experts for the UK as well as from Norway, Denmark and Austria participated. They agreed on eventual and staged recommendations to be achieved by new build and existing homes in Scotland. The following was recommended for all new build homes in Scotland: Net zero carbon buildings (i.e. space and water heating, lighting and ventilation) by 2016/2017, if practical. Two intermediate stages on the way to net zero carbon buildings, one change in energy standards in 2010 (low carbon buildings) and another in 2013 (very low carbon buildings). The 2010 change in energy standards for non-domestic buildings should deliver carbon dioxide savings of 50% more than 2007 standards. The 2010 change in energy standards for domestic buildings should deliver carbon dioxide savings of 30% more than 2007 standards. The 2013 change in energy standards for non-domestic buildings should deliver carbon dioxide savings of 75% more than 2007 standards. The 2013 change in energy standards for domestic buildings should deliver carbon dioxide savings of 60% more than 2007 standards. Backstop levels of U-values and airtightness for building fabric should be improved in 2010 to match those of Nordic countries, but consideration must be given to the social and financial impact of measures that would necessitate mechanical ventilation with heat recovery in domestic buildings. The ambition of total-life zero carbon buildings by 2030. The Code for Sustainable Homes was introduced to replace Ecohomes which was the energy assessment rating for all homes in B.R.E.E.A.M. (R). The CSH was intended to be a single national standard for design and construction of sustainable homes. The code complements the system of Energy Performance Certificates (EPC) which was introduced in June 2007 under the Energy Performance of Buildings Directive (EPBD) (R). All new homes (and eventually all homes, when they are sold or leased) will have an EPC which provides key information about the energy efficiency/carbon performance of a home. The CSH and EPC and energy assessments used the same terminology. The CSH was developed by using the existing Building Research Establishments (BRE) EcoHomes System. The Code has a scoring system of six levels. The different levels are made up by achieving both the appropriate mandatory minimum standards together with a proportion of flexible standards. Level 6, being the highest level achieves a Zero-Carbon Home standard. The Code has been designed so it is closely linked to the Building Regulations, which are the minimum standards by law. The minimum standards for the Code compliance have been set above the requirements of the Building Regulations. The Code has been set out as a baseline in relation to carbon emissions from energy use in a home. The introduction of the Code for Sustainable Homes will encourage developers to build to higher standards. Homes that will be constructed to the higher standards set out in the Code will produce lower levels of CO2 and generate lower energy bills for the occupants. Including the 6 level scoring systems is a good opportunity for developers and buildings to try various construction techniques and see what level they can achieve. The levels are a good stepping stone to achieve a level 6 score and obtaining a zero-carbon home status. The Code for Sustainable Homes was designed to show how sustainable a home could be. Sustainable homes should include the three pillars of sustainability: Environmental, Social Economic. In the Code, only one of these pillars is addressed, Environmental. For the Code to be truly sustainable the social and economic issues need to be included in the design, construction and operation of all new homes. The location of new homes, either in a rural or built-up area could be added to the weighting system for points scoring. Constructing a home within a certain distance of a public transfer route could also gain points on the scoring system, this would reduce the home owners daily car use and CO2 emissions. The government or local authorities could have specially designated areas, preferably Brownfield sites that could be classed as sustainable sites. A points system could be incorporated into the CSH for constructing a new home in this area. As transport makes up over 23% of UKs GHG emissions (R), encouraging alternative-fuel vehicles and electric cars would be beneficial. An alternative-fuel top up station could be constructed within these proposed sustainable sites area. This would meet some of the economic issues by creating employment within the green industry. Until the social and economic issues have been addressed, we should consider contacting the Department for Communities and Local Government and asking them to rename the Code for Sustainable Homes to the Code for Environmental Homes. Planning Laws: As stated in Section 1.0, Zero-Carbon Homes will have to incorporate either on-site renewable technologies or locally sourced combined heat and power (CHP) for their energy needs. The National Planning Policy Statement 22: Renewable Energy gives national guidance in England, on the installation of renewable technologies. Statement 22 was last updated in 2004, but has been supplemented by the updated Planning Policy Statement 1: Planning Climate Change published in 2007. Currently there is a consultation draft to be updated and published before the end of this year (2009). The equivalent planning statement in Scotland is the National Planning Policy Guideline 6: Renewable Energy Developments. It provides the Scottish Executives policy on national land use and planning matters regarding renewable technologies. New permitted development rights introduced on 6th April 2008 in England and the 12th March 2009 in Scotland have made it easier to install renewable energy technologies such as solar panels and biomass boilers(R). These permitted development rights have lifted requirements for planning permission for most domestic micro-generation technologies. In England, The General Permitted Development Order (GPDO) gives rights to certain forms of development on the home without the need to apply for planning permission. In Scotland, these rights are under the Town and Country Planning (General Permitted Developed) (Domestic Micro-generation) TCP (GPD) Scotland Amendment Order 2009. Currently the Welsh Assembly Government and Northern Ireland Government are considering changing their legislation to permit certain renewable technology development without having to apply for planning permission. Both governments hope to introduce legislation in 2010. The GPDO in England and the TCP (GPD) in Scotland include the following technologies: Solar PV Solar Thermal (Roof Mounted) Solar PV Solar Thermal (Stand Alone) Wood burning boilers and stoves Ground source heat pumps Water source heat pumps Air source heat pumps Micro and small wind (due to legal technicalities not included yet but further legislation expected later this year) The DPDO and TCP (GPD) are for guidance only. Each local authority has their own regulations that are set exclusively for their area. For example, a dwelling constructed within a conservation area would have to comply with stiffer standards with regard to installation of renewable technologies towards a dwelling not located in a conservation area. The Mid-Lothian Local Plan was published in 2007 and within NRG2 Individual Wins Turbines and Micro-Generations it states, The Council will support development that proposes the use of individual and community scale wind turbines and other micro-generation technologies for localised power requirements, provided they are located to minimise any potential adverse impact on the local community. The cumulative visual impact of such proposals will be taken into consideration when assessing individual planning applications There certainly is a good system in place in allowing the installation of certain renewable technologies without the need for applying for planning permission. The National Planning Policy Statements (England) and National Planning Policy Guidelines (Scotland) provide national frameworks which help local planning systems to evolve and deliver sustainable development. The current planning system is definitely driving us towards a sustainable future and the possibility of making ZCHs a reality by 2016. It is great to see that certain micro-generation technologies do not need to apply for planning permission, even if certain restrictions apply. But the main concern for home developers and owners is the cost of these technologies. Grants Incentives To construct a home that achieves a Level 6 in the CSH and a ZCH status requires new construction techniques and materials. There might be a higher initial cost to incorporate these techniques and materials than constructing a current standard home, but energy savings can be achieved over the whole life cost and operation of the home. The cost of constructing a ZCH is greater than a standard home because of the requirement to install renewable technologies. The cost of renewable energy generation depends on which type of technology is going to be installed within a home. In the UK, the government, energy suppliers and local authorities all provide grants towards installing renewable technologies into your home. The Department of Energy Climate Change (DECC) low carbon building programme provides grants for householders. The grants are available for micro-generation technologies including Solar PV, wind turbines, small scale hydro, solar water heating, heat pumps and bio-energy. The programme also funds renewable CHP, micro CHP and fuel cells. In Scotland, the Energy Saving Scotland home renewable grant scheme provides grants for homes. It is funded by the Scottish Government and the Energy Saving Trust. Funding is set at 30% of the installed cost up to a maximum of  £4,000. The grant covers Solar water heating, solar PV, solar thermal space heating, small scale wind and hydro systems, ground source and air source heat pumps and biomass boilers and stoves. In Scotland, you have the choice to apply for an Energy Saving Scotland home renewable grant or a low carbon buildings programme grant, but you cannot apply for a grant from both programmes for one technology. The grants available help towards the cost of the installation of renewables, but are they enough? With the current economic climate, people are being very careful with their money. Renewable technologies can save money over the whole life costing of a home, but its the initial cost that is important to people now. The grants available should be increased to really entice people to purchase these technologies. There are also feed-in tariffs available, if a home is generating more electrical energy than it needs, it can sell it back to the main energy suppliers. There are currently two main types of feed-in tariffs available, the Export Tariff, where you are only paid for the electricity you export to the electricity network and the Generation tariffs, where you are paid for all the electricity that your system generates even if you use it in your own home. There are also some Set Price Tariffs available where a fixed amount is paid by the energy supplier based on the type of system installed. The tariff feedback system is a chance for all consumers to become producers. All homes could become energy-plus which could make the UK a net exporter of renewable energy in the future. In Germany, they have been using a feed-in tariff system for over 10 years. It has been a huge success. Under the German system anyone generating electricity from solar PV, wind or hydro is guaranteed a payment of four times the market rate for 20 years. This reduces the payback time for cost of the renewable technologies to less than 10 years and after the payback time is complete, the home owner has a regular income from the electrical company for the power they generate. The cost is spread by generating companies among all users and has added about one cent/kwh to the average bill, or an extra à ¢Ã¢â‚¬Å¡Ã‚ ¬1.50 ( £1) a month (R). The growth in home electric generation and renewable technology use in Germany has created jobs and reduced the initial cost. With more companies competing for a share of the market, they have lowered their prices, a typical 3kw PV system costs about  £17,000 in Britain but less than  £10,000 in Germany (R). It has been proven that the feed in tariff system in Germany is lowering the initial cost of renewable technologies, creating employment and generating income for the home owner after the payback period is over. This system should be introduced worldwide, and promoted as a sustainable method as it incorporates the three pillars of sustainability: environmental, social and economic. Certifying Agencies BREEAM (BRE Environmental AssessmentMethod) is the leading and most widely used environmental assessment method for buildings. It sets the standard for best practice in sustainable design and has become the de facto measure used to describe a buildings environmental performance (R). An Energy Performance Certificate (EPC) is required for all homes whenever built, rented or sold. If you are buying or selling a home it is now law to have a certificate. They are also required on construction of new homes and are needed for rented homes the first time the property is let after 1 October 2008. The certificate records how energy efficient a property is as a building and provides A-G ratings. These are similar to the labels now provided with domestic appliances such as refrigerators and washing machines. The UKs governments Standard Assessment Procedure (SAP), assess the energy performance of dwellings and produces the EPC. Energy performance is based on consumption per unit floor area, energy cost rating (SAP rating), an Environmental Impact rating based on CO2 emissions (EI rating) and a Dwelling CO2 Emission Rate (DER). The SAP rating is based on energy costs associated with space heating, water heating, ventilation and lightings, less cost savings from energy generation technologies. The SAP rating is expressed on a scale of 1 to 100, the higher the number the lower the running costs. An EPC is always accompanied by a recommendation report that lists cost effective and other measures (such as low and zero carbon generating systems) to improve the energy rating. A rating is also given showing what could be achieved if all the recommendations were implemented. EPCS are produced by accredited energy assessors. Whats happening now? Some local authorities in the UK have been making exemplar progress in delivering a low carbon economy, such as Fife in Scotland and in the near future, Merseyside Council are to become the biggest UK low carbon economy (R). The Zero Carbon Hub is a web-site set up by the Government to help you understand the challenges, issues and opportunities involved in developing, building and marketing low and zero carbon homes. The Zero Carbon Hub shares practical experience and uses this information to accelerate main stream adoption of low and zero carbon methods and technologies. The web-site identifies successful examples of low and zero carbon housing solutions. This will help identify successful design, method, technologies and approaches. Currently major house developers within the UK are constructing prototype zero carbon homes. They are using the developments as exemplar projects on techniques and technologies needed to be included within a home to achieve Zero Carbon status. The following developers and companies have all developed a zero carbon home. Stewart Milne Group Sigma Project Kingspan Off-Site The Lighthouse Creo ProKoncept The Creo House Barratt Developments Plc The Barrett Green House Miller Homes Ltd. Miller Zero Housing Project Tarmac Ltd Level 6 Home University of Nottingham It is encouraging that the major house developers are constructing their own example of zero carbon homes that can be mass produced. They are experimenting with new techniques and materials and then sharing their results and information so everyone benefits. The Stewart Milne Group claim, for their Sigma project to achieve a Level 6 on the CSH, the initial cost for renewable technologies is currently from  £60,000- £70,000. They suggest we should be concentrating on super-insulating our homes instead of trying to generate energy. They make a valid point here, if we super insulate our homes we will need less energy to heat it, requiring less renewable technologies to generate electricity. It is highly likely that by 2013 many of the sustainability stumbling blocks for the UK will have been swept away by neccesity. Retrofit solutions to existing properties must be part of the future. If only our banks were to protect their assets by financing a UK wide improvement programme. As practitioners of sustainability we have the following summary for you all What is a zero carbon home? A zero carbon home would qualify for zero stamp duty if its design emission rating (DER) were a negative number and its Heat Loss Parameter HLP sufficiently low. At present; the embedded energy of the materials used the energy from appliances and fittings and fixtures the energy associated with transport and servicing are not included. The term low carbon home is rather vague and ambiguous for the consumer Regards The impact of achieving the 25 per cent and 44 per cent improvements above the current Part L standard in 2010 and 2013 is estimated to have a net impact on the economy up to 2016 of around  £1.9bn. These costs are based on assuming that developers choose technologies on the basis of minimising the capital costs of construction. However, if the impact of on going costs and benefits is taken into account in technology choices, then the overall cost to the economy is reduced to  £0.85bn, which is nearly half of the  £1.9bn cost. Under this scenario there is a slightly higher capital outlay (the percentage increase in Part L above 2006 in 2013 is 6.2 per cent compared with 5.4 per cent when the capital costs are minimised), but the difference in size of the ongoing benefits is clear.

Hank Williams Jr. :: essays research papers

Hank Williams Jr. Hank Williams, Jr. was meant to be a superstar from the day he was born. His father, the legendary Hank Williams, and mother, Audrey Sheppard, both played an intricate part in his early stardom. Hank had to overcome many obstacles in his life including escaping from his father's shadow and a near death experience in 1975. Hank's many triumphs, and his ability to overcome setbacks, have propelled him to a legendary status. Born May 26, 1949, in Shreveport, Louisiana, Randall Hank Williams, Jr. was destined to become a star. Tragically, his father died on New Years day, 1953, at the young age on twenty nine ("Official Home Page," Biography). However, his mother, a country singer in her own right, helped Hank Jr. start one of the earliest, and most successful, childhood careers in country music history. Hank appeared on stage for the first time at the young age of eight. Hank appeared on the Grand Ole Opry at the age of eleven, singing his father's songs in his father's style. At the age of fourteen Hank recorded his first album, a hit rendition of his father's "Lone Gone Lonesome Blues." At an age when most young boys are playing Little League baseball or football, Hank was learning the piano from Jerry Lee Lewis, appearing on the Ed Sullivan Show, and performing before crowds of up to twenty thousand. In 1969, Hank teamed up with Johnny Cash to perform in the largest country concert to date. In 1970, Hank signed the biggest recording contract in the history of MGM Records. As proud as he was of being the son of Hank Williams, Hank got tired of being in his father's shadow. In high school, known as "Rockin' Randall," Hank played contemporary rock, however, that had to be kept secret from all his traditional country fans. He also liked to listen to rhythm and blues, however, these types of music were looked down on by many in Nashville. Later in his career, Hank even released a couple of rock singles under the name Bo Cephus on Verve Records, a subdivision of MGM. The split between what he wanted to do and what he was expected to do , along with his long-term alcohol and drug abuse, developed into a downward spiral of his career that led to a 1974 suicide attempt. In early 1975, Hank recorded "Hank Williams, Jr. and Friends," his first true step to escaping his father's shadow and the past. Although the album was a success, MGM wanted him to return to the style that would keep his longtime

Robert Frost Home Burial - A Reflection of Reality Essay -- Home Buri

Home Burial as a Reflection of Reality Robert Frost's "Home Burial" is a masterfully written work, conceived from his and his wife's anguish at the loss of their first-born son as well as from the estrangement between his sister-in-law and her husband due to the death of their child. In Donald J. Greiner's commentary on Frost's works, "The Indespensible Robert Frost," it is revealed that "Mrs. Frost could not ease her grief following Elliot's death, and Frost later reported that she knew then that the world was evil. Amy in "Home Burial" makes the same observati Often it seems that writers have their own personal inspiration that fuels a great work to cause its readers to realize the complexity of the human nature. Robert Frost's "Home Burial" is a masterfully written example of such works, conceived from his and his wife's anguish at the loss of their first-born son as well as from the estrangement between his sister-in-law and her husband due to the death of their child. In Donald J. Greiner's commentary on Frost's work s, "The Indespensible Robert Frost," it is revealed that "Mrs. Frost could not ease her grief following Elliot's death, and Frost later reported that she knew then that the world was evil. Amy in "Home Burial" makes the same observation". "Home Burial" illustrates the cause of the failing marriage as a breakdown of communication, both verbally and physically, between two people who adopt totally different views in the midst of crisis. Amy does not believe that her husband is in mourning over the death of their child. Her view can be defended by the fact that she is feeling unimaginable pain that she justly feels is unique to the nurturing nature of a mother. The child tha... ...eir ability to talk normally to eachother, but also because the physical side of their marriage is absent. Touch is a form of communication that the total absence of alone can destroy a loving union. Frost leaves the reader with a realistically portrayed image of their marital turmoil reaching a height as Amy opens the door, ready to walk out on the marriage. The melancholy conclusion to Frost's work ends up being the result of failed communication. "Home Burial" is unfortunately a reflection of the reality that many marriages fail in the event of a child's death. A lack of communication, both verbally and physically, tears apart two people even without a tragedy as profound as the one that Frost and his wife experienced. Frost's work is an expression of the more serious and traumatic side of nature and reveals the consequences of inevitable human flaws.

How to get DNA from Banana Extraction Essay

I. Introduction DNA is found in all living cells. A polymer looks like a ladder that has been twisted in a helical form. . The sides of the ladder are acknowledged as the backbone of the DNA helix, and are involve of replicating sugar and phosphate units. DNA has a very important responsibility in the cell, as it encodes for all cellular proteins. s. The proteins expressed in a cell classify the distinctiveness of the cell, and organisms are compilation of several cells. Many of our physical characteristics are ascertained by the progression of our DNA. Banana is the general name for herbaceous vegetation of the genus Musa and for the fruit they produce. It is one of the oldest farmed plants. They are inhabitant to tropical South and Southeast Asia. Banana is also used to depict Enset and Fe’i bananas, neither of which fit in to the abovementioned class. Enset bananas belong to the genus Ensete while the nomenclature of Fe’i-type cultivars is vague. Removing DNA from a banana may sound like a complicated task, but it is not very difficult at all. The procedure involves a few common steps which include mashing, filtration, precipitation, and extraction. Squashing exposes a better surface area from which to extract the DNA. Substances are also added that will facilitate break-down cell membranes to discharge the DNA. The filtration step allows for the compilation of the DNA and other cellular substances. The precipitation step allows the DNA to break up from other cellular substances. At last, the DNA is detached from the solution. The DNA will be able to be seen at this stage because huge aggregates will have formed. Abstract: The lengthy, fat fibers of DNA store up the information for the working of the chemistry of life. DNA is present in every cell of plants and animals. The DNA establish in banana cells can be extracted using ordinary, daily materials. We will use an extraction buffer including salt, to split up protein chains that attach around the nucleic acids and detergent to liquefy the lipid (fat) fraction of the banana cell wall and nuclear membrane. This extraction buffer will facilitate and provide us entrance to the DNA within the cells. Rationale: Students will monitor first hand that DNA is in the food they consume. Students will study the simple technique of extracting DNA and each step is essential. To learn how chemical substances can split up the cell structures adjacent to DNA. To see how DNA looks like in food. To learn and see the physical structure of DNA through the naked eye. Statement of the Problem: Is the process of human DNA extractions similar from the banana DNA extractions? Hypothesis: If the process of extracting the DNA of human will be similar to extracting the DNA of banana then both of the proteins will isolate because in extracting DNAs of different kinds of cells (plants or animals), purification is the first step in the study and handling of DNA that allow scientists to see the genetic syndrome or pattern of chain ladders in each kind of cells. Although, plants and animals have different structure of cells but both create DNA in nucleus. Scope and Limitations: The scope for this lab is that DNA has critical part of each living thing, giving every cell its individual uniqueness, yet it is simply extracting from a cell. It would be appealing to watch this experiment open out in a laboratory with tools strong enough to observe this procedure and to see the individual strands of DNA. In addition, DNA might have been hard to understand but it’s amazing how this lab can see a lengthy DNA strands coiled. Lastly, it covers the aspect of the cells in nucleus and how the information of the DNA is kept deeper in human’s body, animal’s body, plants even in long or short period of time. DNA is a real secret hiding from every tiny cell in our body and surroundings. Lastly, we used the fruits to extraction because it’s a polyploidy. The limitation of this lab is that the limit of comparing the DNA of an animal cells such as meat and plant cell because there will be an expensive material’s going to be use in extracting animal cells, mainly spinach, broccoli, chicken liver, peas. What I did froe experiment is to compare through internet. The limitation would also be the temperature for isopropyl alcohol. The isopropyl alcohol must be kept cool at most time. Lastly, the precipitated DNA can cause poor outcome because of splitting up the DNA strands. Terminology: Chromosome- A threadlike linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information. DNA- Deoxyribonucleic acid; a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. Filtration-The act or process of filtering; the mechanical separation of a liquid from solidify particles floating in it. Precipitation- the condensation of a solid from a solution during a chemical reaction Polyploid- more than two copies of chromosomes in cell, meaning lots of DNA II.

Methodology: 1. Get all the materials. 2. Cut the banana in smaller pieces. Put the entire banana in the Ziploc bag. Seal them tightly. 3. Mash them for 2 minutes. 4. In a plastic cup, mix the 1 tsp. of dish soap, 2 pinch of salt and 4 tsp of water. Stir thoroughly until the dish soap is dissolve in water. 5. Add the mixed solution to the mashed banana. 6. Next, make a well with the coffee filter and place it on a cup. Do not let the filter touch the bottom of the cup. 7. Pour the liquid mixture to the filter paper and filter it for 3-5 minutes. 8. In a test tube, fill the narrow tube with a super cold isopropyl alcohol. 9. Add the 2 tsp. of filtered banana mixture slowly, to have two layers of liquid. 10. Let the tube disturb up to 2-3 minutes. 11. There will be a precipitate DNA forming at the tube. 12. To get the DNA, use bbq skewer and twirl it. 13. Place with capped tube filled with alcohol. 14. Clean up all the materials IV. Data and Analysis: DNA accumulated in Banana. The finish product looks like: Chemical| Functions| Dish soap| Dispersing the lipid membranes | Salt| Eradicate the linked proteins| Isopropyl Alcohol| Precipitate the DNA| Analysis: When mashing up the banana in the Ziploc, it helps the cell wall, nuclear membranes and cellular to break down. The extraction buffer helps to discharge DNA from the nearby cell components of the mashed banana. The filter makes easier to liquefy and removes bigger particles from the solution and extracting smaller cell components such as the proteins of the banana. When the filtrate alcohol is added, the DNA precipitated out of the solution. The DNA looks like a white, cloudy or fine stringy substance. DNA is not visible as a single strand to the naked eye, however, if there’ are thousand of DNA strands present; we will be able to see the large group of DNA threads. Also, DNA is present in all living things in a long or short period, even dead animals or human’s centuries ago. That’s why DNA helps many scientists or doctors to identify genetics of each person and/or lineage. Even different kind of cells has DNA, animals or plants, because DNA is saved inside the nucleus. Also, the process of getting meat and fruits are the same because the experiment is to extract and purify the cell components and leave out all the unneeded substance to do the process. That’s why we used filter and dish soap. V. Conclusion/ Recommendation I therefore conclude that the process of extracting meat and fruits are the same because it has cell components and have same parts. The DNA of all kinds of cells is hidden in nucleus where they bring out the genes of each class and family of an organism. Even the person is dead or mummies can be extracted by DNA because there’s a cell living inside us. In doing this experiment, splitting up the cell wall, nuclear membrane and plasma membrane is important. So does in the meat extractions, because this three cell components is present with plant and animal cell. In the lab, DNA extractions collected the sample cells. Second, breaking open the cells to get rid of the lipid membranes. Then, after DNA is free from the cell, it precipitated the DNA as of the solution. Adding salt to the solution triggers the cellular debris and unnecessary proteins in the solution to cluster together. Finally, the isopropyl alcohol is added and assorted into the solution. Since the DNA is not soluble in the alcohol, it will precipitate and become perceptible to the naked eye and simply tested.
