INTRODUCTION Global warming is defined as temperature increase world wide due to green house gases emission and cause deletion to ozone layer [1]. It mainly occurred due to the burning of fuel, Green house gases include chloro- fluorocarbon (CFC), carbon dioxide, nitrous dioxide, methane, sulphur dioxide. Carbon dioxide, sulphur dioxides are the major gases that cause global warming, co2 and so2 are mainly emitted from the burning of fossil fuel. Don’t waste time! Our writers will create an original "Production Reduce Global Warming Example For Free" essay for you Create order Bio fuels are replaced for petroleum or fuels from fossils and they emit very low amount of sulphur dioxide and carbon dioxide [2]. The bio-fuels are also used as the either partially or totally substitute in vehicle engines [3]. BACKGROUND Bio-fuels are the fuels obtain from plants (www.biomass.uk.com/glossary.php). And these fuels are gaseous, liquids or solids. Liquid bio fuels are categorised into bio diesel, bio alcohol and bio Ethanol[4].ethanol is bio-fuel, is mainly produced from corn while alcohol distillation. Ethanol is a produced more from sugar cane and maize as compare to the corn [5]. CRITICAL ANALYSIS OF CASE: (Are bio-fuels a feasible option? By Jose Goldemberg, Patricia Guardabassi) According to the case, Brazil is one of the highest producers of ethanol from sugarcane (Goldemberg, 2007).Ethanol is a good alternative for gasoline (Moreira and Goldemberg, 1999),ethanol produced in brazil from a sugar cane can be used as a substitute for gasoline(Mathews, 2007), If ethanol is from agricultural product it does not contain any impurities like sulphur dioxide which commonly found in fossil fuels and proper practices of agriculture reduce green house gases(Goldemberg, 2007), united state states producing ethanol from maize leads to deforestation (Laurence (2007) ),reduction of greenhouse gases cannot reduced only by decreasing but also decreased by environmental indicator factor like deforestation and reducing ash (Searchinger et al. (2008)).when compare with gasoline produced from maize and sugarcane ,maize emits 18%less CO2 where as from sugarcane reduce about 91%less CO2(Goldemberg, 2007).the world 6%of land is used for cultivating crops, so bio-fuels results pri ce of crops increased(FAO, 2007).but not all bio-fuels have same impact on prices of food ,the ethanol produced from sugar in brazil have no impact on sugar prices (Goldemberg, 2007).The larger amount of ethanol is exported from southern hemisphere countries like brazil, which has good agricultural resources like land and climatic conditions suitable for sugar cane used for ethanol production(Mathews, 2007),so production from sugarcane decrease deforestation( Searchinger et al. (2008)). The use of bio-fuels decreases pollution, deforestation and also no effect on the price of crops. Case study about Biodiesel from microalgae According to the articles biodiesel is also produced micro algae .Micro algae are driven from sunlight cell that is used for the production bio-fuels, foods by utilization of carbon dioxide (Walter et al., 2005), it produces different types of renewable fuels. micro algae can be obtained from hydro carbons, lipids (Banerjee et al., 2002; Metzger and Largeau, 2005; Guschina and Harwood, 2006), Methane is produced from algal biomass by algal digestion (Spolaore et al 2005).biodiesel from liquid algal biomass (Gavrilescuand Chisti, 2005) algal biomass can be produced majorly by two process raceway pond and photo synthesis bio reactor; the raceway ponds is 0.3m diameter circular pounds having pure water is used for biomass production and in photosynthetic bioreactor production consist of an array of glass or transparent plastic tubes and photo bioreactor is used for capture of sunlight and it produce more biomass as compare to the race pound in a hectare. The us government is sponsorin g for the study of biomass production of race way pond (Sheehan et al., 1998), fuels produced from the algae government kept regulations such as ASTM bio diesel standard6751(Knothe, 2006) and EU have certain standards for biodiesel used for transportation such as STANDARD EN 14214 and STANDARD EN 14213(Knothe, 2006).the cost of production by photosynthetic bio reachtor is cheap compare to race way pound and the cost of biomass per kg is $2.9 to$3.5(Humphreys, 1991; Molina,Grima et al., 2003). So production cost can be decreased by using genetically modified and photo engineering technologies, so production of biodiesel from micro algae can be used as alternative for fossil fuels. Comparison; Both the cases are related to production of biofuel in terms of economical and environmental factors, In the case about ethanol from and biodiesel from algae are used for the substitute for the fossil fuels. Majorly Brazil is using sugar cane for the ethanol production (Goldemberg, 2007)where as now US is developing technology for the production biodiesel from biomass(Sheehan et al., 1998).Ethanol and biodiesel reduce sulphur dioxide .ethanol from sugar cane decrease deforestation and in the case of bio diesel from algae produced from waste water treatment such as photosynthetic bioreactor and race way ponds, brazil have favorable climate for the production of sugar and for the algae is suite for all types of climates and mainly from waste water but it is in experimental level and no company producing from algae, Ethanol produced from the sugar cane decrease 91%of co2(Goldemberg, 2007), But biodiesel production from biomass by use of co 2 which is produced by power plants using fossil fuels(Sawayama et al., 1995; Yun et al., 1997). Ethanol production leading to the deforestation but in the case of biomass production only by sunlight and water, ethanol produced from sugar cane economically efficient but in case of production of biodiesel it is very costlier. Bio fuel from crops has negative effect like food prices. Ethanol produced from sugar is used as gasoline and methane is produced from biomass .ethanol can be produced by Conclusion There are many benefits for the environment, economy and consumers in using bio-fuels. Bio-oil can be used as a substitute for fossil fuels to generate heat, power and/or chemicals. Bio-fuels are made from biomass through thermochemical processes such as pyrolysis, gasification, liquefaction and supercritical fluid extraction or biochemical processes. Biochemical conversion of biomass is completed through alcoholic fermentation to produce liquid fuels and anaerobic digestion or fermentation to produce biogas. In wood derived pyrolysis oil, specific oxygenated compounds are present in relatively large amounts. Basically, the recovery of pure compounds from the complex bio-oil is technically feasible but probably economically unattractive because of the high costs for recovery of the chemical and its low concentration in the oil. Ethanol, bio-diesel and bio-gas are the most useful fuels from agricultural sources. Ethanol demand is expected to more than double in the next ten ye ars. For the supply to be available to meet this demand, new technologies must be moved from the laboratories to commercial reality. The world ethanol production is about 60% by feedstock from sugar crops. Most of the bio-diesel that is currently made uses soybean oil, methanol and an alkaline catalyst. The high value of soybean oil as a food product makes production of a cost effective fuel very challenging. However, there are large amounts of low cost oils and fats such as restaurant waste and animal fats that could be converted to bio-diesel.

The Autocratic Leader Free Essays

1. Introduction to Autocratic Leadership There are several effective leadership styles used to run organizations. The autocratic style basically tells employees what to do. We will write a custom essay sample on The Autocratic Leader or any similar topic only for you Order Now This style is defined as excessively demanding, with one way of communication-from management to employee. Managers possess the power to coerce â€Å"subordinates† to accomplish the mission. Decision making comes from the leader(s) and the opinion or input of the employee is not considered. Nevertheless, autocratic leadership can be useful in certain situations or types of businesses. At times, management must utilize this type of leadership to achieve important goals. 2. Martha Stewart – An Autocratic Leader Autocratic leadership is a management style that places pressure on employees to produce a product, service or image. This style is reminiscent of a dictatorship but in some businesses or military organizations, this type of leadership is necessary. Many employees have worked with an authoritarian manager and are used to it, require it, and even expect it. A good example of an autocratic leader is Martha Stewart who has built an empire based on her teaching techniques for simplicity and creativity in the home: cooking, crafts, finding the perfect housewares, etc.; all accomplished with great attention to detail. Whether people have admired Martha Stewart or not, one cannot argue that she has remained careful, consistent and demanding of her employees. She’s very successful in nearly all of her endeavors, and often, if not always, has used an autocratic management style. It’s common knowledge that it’s her autocratic leadership style that has made her a success in nearly every form of media. Martha Stewart’s critics (who are many) argue that she would have found even more success had she not relied so heavily on the autocratic style of leadership. 3. Autocratic Leadership in the Group Project Setting Another circumstance where autocratic leadership can be helpful is while working on group projects. When a group has no designated leader, a project can fail. When each group member expresses their own opinions and tenaciously holds to them, conflict is sure to arise. In this circumstance, project quality may suffer or literally come to a standstill. Groups need an autocratic leader who can hold to the decisions made by or for the group. The leader should seek for solutions to problems that arise in the project and then delegate the task to the members of the group. Steve Jobs, founder of Apple, Inc., was a very successful autocratic leader. He was typically authoritative and made every major final decision for Apple. Some argue that autocratic leadership can never lead to success – it’s controlling and solely based on the personality and style of the manager. But an effective autocratic leader can achieve great success in bringing a project to completion. During the first stages of developing an entrepreneurial organization, implementing an autocratic leadership style will enable the company to have and keep direction and momentum. A leader who is autocratic should apply his/her style wisely and with trepidation. How to cite The Autocratic Leader, Essay examples

The local authorities such as South Gloucestershire council can only acknowledge the findings. The patients were put at risk by breaching their safety for not having properly trained staff. Not all of the alerts were passed onto the NHS which shows a lack of communication and vital information not being cascaded via the right route. This is clearly a total lack of respect for the patients and their relatives or friends. The place was unsafe and professionals failed to demonstrate their duty of care by promoting an unworkable management structure with poorly paid and untrained staff. Despite receiving public concerns and complaints from visitors or patients themselves, nothing was brought forward so that a disaster could be avoided. The report resulted after a parent secretly filmed images which proved how distressing the place was with all sorts of abuse being common practice. The effective and human delivery of assessment, treatment and rehabilitation had been completely undermined.

C. http://www. bc. co. uk/news/uk-18581253 In the wake of the Winterbourne View Hospital near Bristol, the Care Quality Commission found that 48% of inspected premises (hospitals amp; homes) did not meet the required general care and welfare standards. The report highlighted the fact that there is a failure to treat the residents as individuals and that people were staying for years in centres intended for short-term care. The use of restraint was also pointed at and an â€Å"urgent need† to reduce its use was requested. There is a case of a man called James who had severe learning disabilities and autism who had spent years in different homes. He suffered sexual and physical abuse which made him a â€Å"different human being† said his Mum. Therefore, as a result of those findings, the new commissioning bodies, the clinical commissioning groups, are asked to pay special attention to people with a learning disability. Also and to conclude, the private sector seems to be more at risks than the NHS.
