Helping the Environment Essay Example for Free

Helping the Environment Es thinkTrees are very historic to humans. As part of the environment, we moldiness. More and more trees are being cut to sustain the needs for products such as paper. Making small ways to ease the environment is important to make a difference. As a hypothesis, I presume that pr unconstipatedting the expenditure of paper towels and napkins that are made from trees can help the environment. The use of cloth as napkins paper instead of those made of paper at homes, restaurants and other places have significant contributions to the demand of paper products. Paper towels and napkins are fluid products made of paper. It serves the same general purposes as conventional towels, such as drying hands, wiping windows and dusting. However, cloth and rugs and ordinary towels can serve the same purpose. It is also more durable. It bequeath wiser to use cloth instead of paper napkins since it is cheaper to use because cloth can be washed and used again. . If you r eplace the majority of paper towels and napkins with cloth rags or cloth napkins, the savings to the environment are tangible. The average cost of paper towels is about anywhere from 1.00 to 2. 25 per roll depending on the brand. The demand for paper products such as napkins has a huge impact on the amount of trees being cut. According to the Law of Supply and Demand, as the demand increases the corresponding supply must be produced. It implies that, as the demand for paper towels and napkins increases, more trees are more likely to be cut down in order to address. I would say I use at least 4 roles of paper towels a week with approx. 100 sheets a roll and its 2 ply sheets which is just a stronger type of paper towel.In order to contribute something to the environment, one should avoid using paper products like paper towels and napkins. Instead of disposable napkins, use a handkerchief. A campaign for not using such products can also have significant effects on the number of trees t o be cut. In conclusion, even in small things we can contribute big changes to help the problems in the environment. We should all be aware of the consequences of our daily consumption.REFERENCESTsien, Tsuen-Hsuin, Paper and Printing, vol. 5 part 1 of Needham, Joseph Science and Civilization in China.

Reverse Logistics Processes

Reverse Logistics ProcessesDefinitionsThe transit of planning, implementing, and controlling the efficient, cost effective flow of nude materials, in-process inventory, finished goods and related information from the point of origin to the point of consumption for the purpose of conforming to client requirements. Logistics is defined by The Council of Logistics ManagementWhat is Reverse Logistics?We key to the term resign logistics as all activity associated with a growth/service after the point of sale, the ultimate goal is to optimize or trifle more efficient after grocery store activity, thus saving money and environmental resources.As equally as Logistics deal with the set of events that move the product to customer, the reverse process moves the product at least on step back in the supply chain. The objective is to regain the value or proper disposal, when the product returns in the opposite direction. The s grey-headed goods get returned due to improper quality control me asures leading to damage, recalls, hazardous materials and obsolescence.,It involves collection, transportation disposal of returned , damaged /surplus goods by dint of reuse, resale, or repair.Importance Of Reverse Logistics.Reverse logistics responsiveness and quality has a direct a positive effect on the companies economic performance. Companies invite to accept returns in the shape of products or materials as a legal obligation. As organizations offer warranty along with sale of items, and to minimize the cost of warranty and sale price, the reversals arrive inevitable for sustaining customer satisfaction and quality assurance. The closer the union is to the end customer, the greater the size and scope of reverse logistics issues. .The worldwide legislations on hazardous materials (WEEE and ROHS), entreat reverse logistics for repairables.Size Of Reverse LogisticsIt is difficult to estimate the cost in Reverse logistics management as many companies do non have systems to estimate. interrogation says it is around 4% of the cost of logistics, based on a survey sample..Return PercentagesThe reverse logistics process bear be divided into two categories depending on the aras of reverse flow which in turn comprises of primary products, or primary of packaging. A Company has varied disposal options to choose once a product has been returned.The company looks primarily to return it to the supplier for a full requite.In case of goods not used may be resold to a different customer or at an outlet store.If goods do not meet required quality levels, then it may be sold to a salvage company that will export the goods to a foreign market.Common Reverse Logistics Activities Activites that comprise of reverse logistics include, Refurbishing, Recycling , landfill, repackaging, returns treat and salvagingKey Reverse Logistics Management ElementsGatekeepingCompacting garbage disposal Cycle TimeReverse Logistics Information SystemsCentralized Return CentersZero ReturnsRemanufacture and RefurbishmentAsset RecoveryNegotiationFinancial ManagementOutsourcingStrategic rehearse Of Reverse LogisticsThe strategic usage of Reverse logistics among the retailers and wholesalers is to reduce the risk of buying products that may not be hot selling items.In some industries goods are distributed with the understanding that retuning the goods for credit is allowed if they are not sold. This encourages retailers to carry a huge stock thereby shifting the risk of having unsold goods (obsolescence) goes to the company. The retail seller at the nearest reach to the customer exploits the situation ordering a huge consignment and resulting in heavy returning.An example of the strategic use of returns in the market is the sale of newspapers and magazines, and the sellers carry more stock for a con lookrable incentive.By doing this the reseller were allowed to return the goods within the stipulated time frame. This facilitated the customers to the inventory low and purchase things in time. each note aims to lock the customers in and not to opt for to another supplier. There are many ways developed by the supplier to link themselves to the customers not to switch to another supplier. One important service that a supplier can offer to his customer is the ability to accept the defective goods immediately and refund the amount well-timed. Every retailer needs to have a strategic vision of the logistics in order for him stand updated in the market.The retailer in short letter of electronic toys can easily get off business if they do not have the knowledge or vision of reversal logistics. Several surveys have estimated that a larger division of the profit was due to the improvised strategies.How An Effective Strategy Can Be DevelopedThe best methodology for an effective reverse logistics to be framed and implemented would be working on the quick process in the business. The traceability and quality management system will identify goods time ly and correctly outlining the features of a product in details and the reasons of defect with a solution of a product when returned.The reverse logistics process can be managed through a tailored program called Enterprise resource planning system. A tailored ERP system can provide varied information related to the returned inventory. It can give the number of returns from the customer, identify the reasons of the returned goods, check the course action to be taken and deal with the product and allocate resources in dealing with the product.An ERP system, equipped with gamy processes, should be sufficient to manage its reverse logistics strategy.The other crucial aspect in reverse logistics is the concept of collaborationism. It works efficiently with a effective collaboration involving a larger visibility. Sharing of information, supporting integrated decision making should be a vital feature of the collaboration. Constant communication and shared processes with a common vision s hould be practiced for a successful institutioning and implementation of Reverse Logistics.This has become a integral part of any business in day to day life which may results in many benefits to the company. Every retailer, manufacturers and producers need to create the necessity of reviewing the logistics followed. They can work on their existing systems that trying to find ready made solutions.The companies have developed various simple and effective strategies for running a successful Business.The various steps or factors involved while defining at effective reverse logisticsSecurityShipping and ReceivingLabourThe Return PolicyInspect ReturnsAssign Disposition realistic Examples or Practical Examples of Effective Reverse Logistic.Reverse logistics is also applied for a different non-commercial cause and used for a reason of charity or gain a mileage augmenting advertisement returns. Such donations get a goodwill to a company and act as a substitute for ads .Henna Anderson Co s Hannadowns campaign retrieves used clothes from the customers and gives an offer on the new purchases. The returned clothes reach the less-privileged ones.As a second example, Kenneth Cole Productions makes offers to customers returning old shoes and given away to the needy. Nike shreds the retrieved old shoes and converts them into basketball courts and tracks.Business ImplicationsDespite the costs, companies do accept returned goods, with original receipt or a fees, as Returns Management is an important strategic tool in a competitive environment. Return policies are in place to influence purchase decision of a customer.Return management is a strategy similar to reverse logistics involving a decision on how the return will be dispositioned. When returns are a financial obligation and restrictions are too many in land filling, then disposal is a less attractive option.Difficulties Of Reverse LogisticsCompanies budget for what is known as discolouration Equity to attach an image to products and can not afford to reduce the value of primary investment , by having their product appear in a flea market.The difference in the objective of the manufactures and retailers exists due to the different strategies followed in managing returns.For Eg, In case a retailer wants to return a good to the manufacturer and he would disagree for varied reasons as followsCondition of the item,Value of the item and the promptness.The assumption by the retailer for returns sent back in pure , pristine conditions and any damage must have occurred in transit or must be manufacturing defects, leads to criss cross of purposes.The inefficiency of the reverse logistics is indicated by the amount of returns inventory being held in the storage warehouse and clearly denotes the way the firm is handling returns.Unfortunately, some symptoms that cannot be identified and observed are as below. These have been defined by Dr. Dawe.For most firms processing returns is not a priority.Focus is o n new generated products revenue and returns received are in more number to the processing or disposal.Declined value of the returns due to obsolescence (computers , expressive style ware).Company policies making it difficult to handle returns as the junk damages quality products.ConclusionFirst, develop strong reverse logistics strategies. Second, clearly outline financial, corporate, branding, marketing and other objectives. Treat it as another business and not a simple operation. Give it goals, give it objectives, give it resources, give it executives and let it be part of the Lifecycle design for your products and your customers.ReferencesCurt Barry, How to Develop a Reverse Logistics Strategy 8 Tactics to Try.Catalog Success Magazine, 2003.+http//www.fcbco.com/articles-whitepapers/Reverse-Logistics-Strategies.pdfReverse Logistics Executive Council, http//www.rlec.org.Stefan E.

Recruitment Strategies: The Hotel Industry

Recruitment Strategies The Hotel IndustryThe beginning of the 21st century was referred as the most difficult phase in the history of tourism labor. This sector was affected negatively because of terrorism, war and global health problems The Economist Intelligence Unit, 2005. However, it was in 2005 that the sector started to open out and in 2004 international arrivals change magnitude at a rate of 8.6% comp bed to 2003 (The Economist Intelligence Unit, 2005). Economist Intelligence Unit (2005) states that there argon many reasons for this kind of relief. The relative stable geopolitical conditions, development of key sectors, such as China, the supply- driven expansion of carriers at low cost, which are currently building inroads in Asia and the Middle East, at presbyopic with the conventional markets of North America and Europe, constant pressure on the prices of many of the industries, pent up demand of former years, covering the SARS (Severe Acute respiratory Syndrome). Even though the climate of the UK is not favourable, the country still attracts many visitors thanks to its natural beauties like lakes, rivers, rugged mountains, coastline and other factors that cover high hackneyed of services, natural attractions and transport services (Youell, 2001).Recently the world is witnessing the significant change in the economy. Indeed, Stavrou-Costea (2005) stated that national economies are changing and as we move increasingly a look from a world in which national economies were relatively isolated from one another into an interdependent global economic system, we are witnessing the rapid taste perception for and development of all aspects associated with and affected by humans resource heed. In fact, Stavrou-Costea (2005) also stated that while the emerging international economy creates opportunities it also presents challenges and threats with which yesterdays line of descent managers did not deport to deal. In this perspective regardless of intent ness and the size of the companies (Ulrich, 1997) managing human resources has become vitally important for the companies in achieving the goals of the organisation (Stavrou-Costea, 2005). Similarly, Dessler (2000) stated that human resources need to be collaborator in developing a unions strategy in order to be successful in organisational goals. Human resource management can help the company reach organizational effectuality and thereby have a determining effect on whether or not the company is good enough, fast enough, and competitive enough not hardly to survive but also to thrive (Schuler and Jackson, 2000 Stavrou-Costea, 2005). Schuler and Jackson (2000) and Stavrou-Costea (2005) commonly stated the difficulty of achieving and sustaining organisational effectiveness without the efficient practises of human resources management.Tourism and hotel industry are supposed to be parts of cordial reception industry. Hospitality industry has becoming a very big of source of employm ent. The rate of employees in hospitality industry is increasing and employees are undergoing certain problems. Some factors contribute to pick and arousement of staff in hotel industry and HRM is facing to solve selection and recruitment problem in hospitality industry like retraining performance ,high- comprehend turnover, low morale ,retraining performers .In an analysis of 5000 jobs advertisements cross tracks a number of different occupations and sector in the UK,Jackson et al.(2005) found that the skills stated as necessary by employers are social skills and personal characteristic only 26 per cent of organizations mentioned the need for educational recruitments. Personal services this rate is less than 10 per cent.As a highly labour-intensive industry, tourism and hospitality organisations are often hard to talk of how their batch are their greatest asset. However even cursory understanding of the disposition of work employment and people management in tourism and hospit ality points to many paradoxes and contradictions that are apparent in studying human resource management (HRM) in the sector.Many academics, industrialists and policy-makers have attempted to define the nature of the tourism industry-and the place of the hospitality sub-sector within this border conceptualization-yet there is still no commonly accepted definition. Hence, there are inherent problems seeking define what is large and diverse sector which means many of the activities may overlap and could be described as encompassing tourism and hospitality. For example Lucas(2004)in her recent work on employment relations in hospitality and tourism industries chose to talk in broad terms about the Hotel, supply and Tourism sector.In some geographical areas and sub-sector areas, tourism provides an attractive ,high-status working environment with competitive pay and conditions, which is in high demand in the labour force and benefits from low staff turnover. On the other hand, it bri ngs low pay, problems in recruiting skills in number of key areas, a high level of labour worn socially disadvantaged groups, poor status and virtual absence of professionalism.More is known about employment in certain sub-sectors than other .For example, the commercial hospitality industry encompassing hotels, restaurants and pubs, bars and nightclubs is the largest sub-sector with around 70 per cent of employees in the UK(people 1st,2006).Unsurprisingly, then, the commercial hospitality industry is well served with extensive research on the nature of employment and HRM strategies(DAnnunzio-Green et all.,2002Lucas,2004).In terms is the predominance of small-and medium sized enterprises is a further issue to consider is the manner. People 1st(2006) note that within the UK hospitality, leisure depart and tourism sector per cent of innovations employ fewer than 10 people and 50 per cent fewer than five. Heterogeneity is also seen in relation to the way that organisations adopt diff ering routes to competitive advantage. For instance, full service carriers in the airline industry are likely to have very different approaches to HRM compared to low-cost airlines(Eaton,2001Spiess and Warning,2005)The same is avowedly for the hospitality sector, which may range from first class and luxury hotels providing extravagant, full 24-hour service to the more homely comforts of a bed and breakfast establishment from fast food restaurants to Michelin starred restaurants .In turn, the jobs provided by these various organizations demand a variety of skills and attributes from those employees interacting with customers, which again will impact on HR strategies such as recruitment, selection and training.Commonly selecting and recruiting and people to fill new or existing positions are a crucial element of human resource activity in all tourism and hospitality organisations, irrespective of size, activity and structure. It has been noted how the importance of service quality ha s increased the pressure on organisations for select right selection.(jameson,2000) pointed this may be especially true in smaller organisations that may not have well developed HRM functions or recruitment and selection systems and may recruit irregularly with heavy reliance on informal system and methods. Certainly, within the context of the hospitality sector, Price(1994) set up that 241 hotels sampled in her research a triad never used job descriptions or person specifications. Lockyer and Sholarious (2005) surveyed over 80 hotels and again found a general lack of systematic procedures for recruitment and selection. inquiry ObjectiveThe ultimate objective of this study is to explore What recruitment strategies applied in the UKs 5 star hotel industry? An exploratory study in capital of the United Kingdom Hotels. .The research objectives can be listed as follows.To review HRM and hotel industry theories.To explore what recruitment strategies in the U.K hotel industry.To evaluate importance of HRM department in the U.K hotel industry.To identify what is the recruitment and selection problems in the U.K 5 star hotel industry.To identify if there are any weaknesses of recruitment strategies applied by the UKs 5 star hotel industryTherefore research questions for this study areWhat is recruitment?What are recruitment processes?What is the importance of recruitment in achieving strategic HRM?In what way the recruitment is important for the service sector players?What is the role of recruitment in the 5 star hotel industries overall business strategy?What recruitment strategies are followed by the 5 star hotel industries?Are there any weaknesses of recruitment strategies applied by the 5 star hotel industries?Design of the StudyIn order to pull through the objective of the study, paper is organised as followsChapter Two consist of a review of the literature on the subject. In chapter two HRM theories and diffusion of recruitment and selection strategies, servic e encounter tasks, definition of 5 star hotel industries are given.Chapter Three includes methodology of this research and consists of research design, sampling methods, info collection methods, data analysis, honourable issues involved in research process and limitations of this study.In Chapter Four, data analysis provided. This chapter divided into two parts secondary data analysis and primary data analysis. In the secondary data analysis U.K tourism industry, recruitment and selection strategies in tourism industry are analysed. In the primary data analysis, interviews that are conducted with the management of the UK hotels are analysed.Chapter Five is the conclusion part of the study and includes some directions for the future researches.

What Are The Effects Of Acid Rain?

What Are The Effects Of Acid precipitatefall down?Part I What is Acid Rain? Acid precipitate is a general term that refers to the deposition of acidic materials from the atmosphere on the surface of the earth. in that locationfore it is more appropriately cal direct acid deposition. There argon devil types of acid deposition, wet deposition and dry deposition. Wet deposition, or acid precipitation, refers to acidic rain, snow, hail or sleet. It occurs when pollutants such as sulphur and Nitrogen oxides (SOx, NOx) ar present in the atmosphere and react with water vapor to form acidic solutions such as siemensous Acid (H2SO3), sulphuric Acid (H2SO4), Nitrous Acid (HNO2) and nitric Acid (HNO3) that fall to gumptiongrounds surface as precipitation. Dry deposition refers to the deposition of particles and gases of Sulphur and Nitrogen oxides (SOx, NOx) on Earths surface. These particles and gases reverse acids when they react with water on the surface of the Earth. Natural p recipitation has a pH of about 5.6. It is slightly acidic due to dissolved Carbon dioxide (CO2). In comparison, acid deposition usually has a pH of about 4.3 5.0.As stated above, acid deposition is groundd by pollutants in the atmosphere. The majority of these pollutants are released in to the atmosphere by the burning of fossil fuels. Fuels such as coal and oil contain Sulphur and when they are burned they elease it. When Sulphur is released into the atmosphere by combustion it reacts accordinglyS + O2 SO2Sulphur released by the burning of fuels such as oil and coal reacts with Oxygen in the air to yield Sulphur dioxide.2SO2 + O2 2SO3Sulphur dioxide reacts with the Oxygen in the air to yield Sulphur trioxideSO2 + H2O H2SO3SO3 + H2O H2SO4Sulphur dioxide and Sulphur trioxide react with water, either in the atmosphere or on the surface of the Earth, to yield Sulphurous Acid and Sulphuric AcidCombustion of fuels in cars releases anformer(a) pollutant, Nitrogen gas. Once Nitrogen gas is released in to the atmosphere by combustion it reacts accordinglyN2 + O2 2NON2 + 2O2 2NO2Nitrogen gas reacts with Oxygen in the air to yield Nitric oxide and Nitrogen dioxide2NO + O2 2NO2Nitric oxide reacts with oxygen in the air to yield Nitrogen dioxide2NO2 + H2O HNO2 + HNO3Nitrogen dioxide reacts with water, either in the atmosphere or on the surface of the Earth, to yield Nitrous Acid and Nitric Acid.Small amounts of these pollutants are besides released into the atmosphere naturally. Decomposing vegetation releases gases that contribute to pollutants in the atmosphere. Lightning produces Nitric oxide (NO) and vol fundamentic eruptions release Sulphur dioxide (SO2).Some atmospheric chemists such as Dr. Ronald Prinn believe that acid rain has been around for millions of years. Dr. Prinn believes that acid rain could be responsible for the extinction of dinosaurs. However, the world-class known observation of acid rain did non take place until the 19th century, arou nd the time of the Industrial Revolution. It was Robert Angus Smith, an English scientist, who came up with the term acid rain in 1872 when he spy that acidic precipitation was damaging plants. Acid rain was not considered a major environmental concern until the 1970s when scientists observed the effects of acid rain on ecosystems. When it was made clear that acid rain has forbid impacts on ecosystems and that it is not only a regional issue but rather an planetary matchless, governments began to get come to. In 1991, Canada and the United States signed the Canada-US Air Quality Agreement and committed to avoid SOx and NOx emissions.Part II How does Acid Rain profess our Society?Acid rain has an extremely negative impact on our auberge. The most devastating meaning of acid rain is the affect that it has on terrestial as well as aquatic ecosystems. In terrestrial ecosystems, acid rain destroys plants. Acid rain causes toxic metals such as aluminum, copper, lead, manganese a nd zinc to disinvest out of rocks and soils. Additionally, nutrients present in topsoil leach down to the subsoil. Plant growth is signifi hobotly decreased in soils lacking nutrients and rich in venomous alumnium. The other toxic metals released by acidic soil kill earthworms and nitrogen-fixing bacteria, both of which are essential to plant growth. Acid rain can also wears past the protective coating of leaves. These consequences also have an effect on the agriculture industry. M both crops cannot grow in soils that are lacking nutrients and contain aluminum. Furthermore, acid rain destroys many a(prenominal) food crops such as radishes, tomatoes and apples. The effects of acid rain extends to aquatic ecosystems. The toxic substances that are leached out of rocks and soil can be water-washed in to lakes and rivers. Fish are easily poisoned by these toxic substances. The acidic environment that acid rain creates in lakes and rivers is also harmful to fish and other aquatic organ isms. The acidity kills many organisms that are usually at the bottom of a complex aquatic food chain. The food chain then collapses and the populations of many organisms significantly decrease. Acid rain also interrupts fish reproduction as it can destroy fish eggs.There are many more negative effects of acid rain. Fresh water supply can be contaminated by the acidity as well as by the metals that are leached from rocks and soil due to acid rain. Acid rain can also corrode water transportation pipes, allowing metal to enter the water supply. Another consequence of acid rain is the effect that it has on a cityscape. Acid rain can significantly damage metal and stone structures. Finally, acid rain can have an affect on human health. Contaminated water can cause health concerns. The SOx and NOx in dry deposition can cause numerous respiratory indispositions such as asthma, emphysema and bronchitis. Furthermore, Nitrogen oxides (NOx) can react with volatile organic compounds in the ai r near the surface of the Earth to yield Ozone, which can be very detrimental to the respiratory system.Part III What should we do about Acid Rain?There are two methods that can be taken when approaching the issue of acid rain. We can either ignore the issue or we can do some affaire about it and look for to control the problem. Both methods have their advantages and outrages. If we ignore acid rain, nothing will be do to control or stop it and we will continue to fulfil from its consequences. The advantage of this method is that no resources have to be expended. Governments, industries and citizens do not have to invest any money in to attempting to solve the problem. Governments do not have to invest in new energy sources. Industries can go on using current techniques without having to invest in new strategies in frame to assist in solving the problem. Citizens can also go on without trying to conserve resources in put up to attempt to stop acid rain. However, the disadvant age of this method is that acid rain will remain a threat to terrestrial ecosystems, aquatic ecosystems, the agriculture industry, cityscapes, fresh water supplies and human health. If acid rain continues the effects could be devastating. The second method is to do something about the problem and attempt to control acid rain. In order to do so pollutant emissions must be reduced, alternative sources of energy must be found and used, resources must be conserved, polices must be put in place in order to protect air quality and lakes and rivers must be neutralized. The advantage to this method is that it has the potential to control or even stop acid rain. By doing so we can save many terrestrial and aquatic ecosystems, increase yield of crops, prevent damage to cityscapes, keep supplies of fresh water clean and eliminate any risk of human health being put at risk due to acid rain. However, the disadvantage to this method is that it is very expensive. It also requires governments, ind ustries and citizens to take action. To reduce pollutant emissions, companies have to invest in new cleaner technology. Such technology includes Sulphur scrubbers in factories and catalytic converters in cars. These technologies are expensive and require a large investment from industries. Furthermore, if policies are put in place in order to maintain air quality, many companies will have to invest in new technology in order to meet these new regulations. In order to find and use new energy sources industries as well as governments will have to invest a large amount of money into research and implementation. Additionally, neutralizing lakes and rivers that have been damaged by acid rain with limestone will also require the government to spend a large amount of money. All of these costs will eventually be passed down to the consumer as well as the citizen. In order to control acid rain we must also conserve our natural resources. This will be very hard for a society that is driven by exploitation. Revenues of many companies might go down if consumers begin to conserve. Revenues also may go down if companies begin consider the environment out front they consider profit. After examining the advantages and disadvantages of ignoring the situation and controlling the situation, I think that we must control it. It would be wrong to ignore acid rain and the advantages of controlling it genuinely outweigh its disadvantages. Controlling and trying to eliminate acid rain will be expensive and require governments, industries and citizens to take action but it is the right thing to do. We must save our ecosystems, our crops, our cities, our water and our health from the detrimental effects of acid rain.Ebola computer virus History, Causes and EffectsEbola Virus History, Causes and EffectsK.G Shayani UpulikaEbola Virus Outbreak The deadline and incurable haemorrhagic fever.Contents (Jump to)1.1 Introduction to Ebola computer computer virus1.2 History of Ebola virus.1. 3 Characteristics of Ebola virus1.4 Symptoms of Ebola virus1.5 Diagnosis methods of Ebola virus.1.6 Treatments for Ebola virus1.7 Conclusion.References1.1 Introduction to Ebola virusIdentification of natural reservoir for Ebola virus was not possible by researchers for decades but recently a scientist named Leroy presented most acceptable evidence that three species of fruit bats called Hypsignathus monstrosus, Epomops franqueti and Myonycteris torquata are wildlife reservoirs for Ebola virus (Biek et al, 2006). Ebola virus is associated with acute fatal hemorrhagic symptoms for human and non-human primates when they get escaped from their wildlife reservoir hosts, Ebola virus is consider as a filo virus and one of the most fatal viruses known the five species of Ebola virus have been identified as Ivory Coast Ebola virus, Sudan Ebola virus, Zaire virus, Reston Ebola virus Ebola and Bundibugyo Ebola virus (Yuan et al, 2012). In the present situation of Ebola virus has a 90% remna nt rate and the main site of prototypal immerging is the region of guinea fowls southeastern forest region and this spilled throughout the faultless Africa and some regions of the world (Bausch and Schwarz, 2014).1.2 History of Ebola virus.Ebola virus was first identified in 1976 in Congo of central Africa, It initially named as Zaire as it first found in town of Yambuku and after Yambuku blast the virus was vanished, but Ebola reappeared again in 1989 (Draper, 2002).The biomedical scientists first discovered the family of virus filoviridea when Marburg virus first appeared in 1967 and at that time commercial laboratory workers with sever and unusual disease symptoms were admitted to hospital in Marburg, Germany (peters and Ledue, 1999). After the discovery of Ebola it has re-appeared cyclically most of the Ebola outbreaks are restricted to rural regions in central Africa and have never participated more than 500 cases, first Ebola case were noticed in February in wild areas of south wop and it has grown so strongly and spread so rapidly in terms of affected people and earthly spread those are Guinea, large move of Liberia and Sierra, Lennon are disease ridden (Klenk, 2014).The virus has persisted in Africa and many fatal outbreaks in human and non-human primates have been reported and the History of Ebola virus is still unreadable when doing researches Ebola virus strains with complete glycoprotein genes, including Zaire, sudan.reston, Tai forest, and bundibugya were analyzed (Li and Chen, 2013). After finding the way of coming the Ebola virus to south Africa scientists have found that the virus have invariably been there in the region but people just never noticed, therefor it has recently introduced then the first report and phylogenetic investigations on the Guinea outbreak proposed that the Ebola virus found in Guinea is a noticeable strain from that observed in central Africa, Therefore Ebola virus is not a newcomer to the region, it has been circ ulating for some time in Guinea,and have plow a sudden threat to human beings (Schwarz, and Bausch, 2014).Figure 1.1 Map of the three countries involved in the 2013-2014 outbreak of Ebola virus as of June 20 2014(Schwarz and Bausch, 2014).1.3 Characteristics of Ebola virusThe family filoviridae with order Mononegavirales contains two generas, as Marburg virus and Ebola virus (EBOV) (Kuhn et al., 2012). Ebola virus is again divided in to many species such as Zaire Ebola virus (ZEBOV) Sudan Ebola virus, Ta forest Ebola virus and Reston Ebola virus (REBOV) (Kuhn et al., 2012). VP40 is the major Ebola virus matrix protein and it plays a major persona in virus assembly and budding. This virus have a diameter averagely 57 .58 nm and it differ slightly for VP40+VP35 at 63.64nm, VP40+VP35+NP at 66.75nm (Johnson, toll and Harty, 2006).Ebola virus particle is uniform with uniform diameter of 80 nm but Ebola virus particles are greatly varying from their morphology including long up to abou t 14 m, sometimes these particles are branched filaments or shorter filaments shaped like 6, u or a circle and the size of this viral genome considered as 19 kb (Cencciarelii et al, 2014). However this fever referred as a group of illness that caused by viruses belongs to diverse range of families which includes Lassa fever, rift vale fever and so on and It may lead to overall vascular damage and usually accompanied by hemorrhage (Ratanshi et al, 2014).Filo virus outbreaks are peculiar(prenominal) because these viruses can intersperse by years or even decades without showing any disease activity and last new species of Ebola virus was found 14 years before in Ivory Coast (Towner et al., 2008). Ebola virus is characterized by secondary transmission and high case fatality and also by threadlike enveloped particles however treating Ebola virus was a challenged situation after transmittal because these virus consists recombinant human activated protein C(rhAPC) ,recombinant nematode anticoagulant protein c2 (rNCPc2), small interfering RNA(si RNA) ( Qui et al, 2014).1.4 Symptoms of Ebola virusEbola virus is an invasive pathogen that can cause a highly lethal hemorrhagic fever in both human and non-human beings this virus runs its course within 14 to 21 days and the infection initially present with non-specific symptoms like fever, myalgia and malaise as infection proceeds long-sufferings starts to show large bleeding and curdling deformities including gastrointestinal bleeding, rash and a wide varieties of hematological irregularities (Sullivan, Yang and Nabel, 2014).The initial symptoms of Ebola virus are non-specific, including fever, rash and vomiting, The most generally experienced symptoms were non- kindredy diarrhea (81%) and asthenia (77%) and cardinal patient reported were observed with hemorrhagic symptoms, and out of seven six of patient died(Roddy et al, 2012).The incubation period after exposure to virus is typically 8 to 10 days but it can be as short as 2 days and extended to 21 days and the net death rate is high as 90%.Most people with Ebola die within 2 weeks of disease onset (Turner, 2014).1.5 Diagnosis methods of Ebola virus.Numbers of newer technologies were applied for the diagnosing of Ebola virus infection some of them are antigen detection assay, utilized extensively in the Reston outbreak and its investigation, these methods allowed a fast and unique recognition of Ebola virus in the blood of severly ill individuals even in rural areas also nonspecific detection of antibodies by the unintended fluorescent antibody test in humans during Reston investigation led to the adaptation of the enzyme (Kaslow, Stanberry and Due, 2014). Ebola virus disease can proved with various lab tests depending on the on the stage of the disease, within a few days of infection immunosobent assay, antigen detection tests, reverse transcription polymerase chain reaction (RT-PCR) assay, and virus location by cell culture is used (Plotkin , Oreanstein an Offit, 2008). after the patient get back to normal immunoglobulin M and Immunoglobulin G can be found, after death immunohistochemistry, PCR and isolation of the virus can be done the assume diagnosis can be done by polymerase chain reaction (PCR) and ELISA antigen testing furthermore clarifications on viral replication inside cells can be done through measurements of IgM antibodies ( Plotkin, Oreanstein an Offit, 2008). Diagnosis of Ebola comes in to play when symptoms and signs of fever, illness, petechial rash and disseminated bleeding are observed and most of the accurate diagnosis is done by using a polymerase chain reaction detection assay and can be confirmed by detection of viral replication in Vero cells (Plotkin, Orenstein and Offit, 2008). Ebola is mainly diagnosed from the symptoms and blood test here mainly looks for the presence of antibodies in the virus at earlier days detecting a infected patient was not easy and once recognized the patient must be isolated and relevant authorities should notified (Horobin, 2008).1.6 Treatments for Ebola virusNo effective treatments for Ebola virus at this time. Anti-viral medications currently available have no effect on Ebola virus. Care for patients with Ebola virus infection consists maintaining fluid and electrolyte equilibrium via oral or I.V. hydration, supporting oxygenation and BP, Adjustments of clotting and treating comorbidities such as a concurrent bacterial infection (Turner, 2014). However without recommended vaccines or treatments Ebola virus management has been limited and barrier methods and prevention methods also become limited but a combination of monoclonal antibodies (ZMapp), optimized from two previous antibody cocktails, is able to rescue 100% of rhesus macaques when treatments is only initiated up to 5 days, high-pitched fever, abnormalities in blood count and vireamia were some evidences in animals before ZMapp invention after that advanced disease as indicated by increased liver enzymes, mucosal hemorrhage and generalized petechial could be reversed leading to a full recovery (Qiu et al, 2014). There are no licensed vaccines currently available against Ebola virus but many applicable vaccine platforms have been tested for their efficiency against the virus and this treatment includes exposed or lipid encapsulated DNA, particles like virus arrangements, vesicular stomatitis virus, strain Indiana, Human parainfluenza virus 3 (HPIV-3) , vaccinia, Venezuelan equine encephalitis virus (VEEV) and replication-deficient human adenovirus serotype 5 (AdHu5) vectors(Richardson et al, 2011). Due to the absence of specific therapies, filo virus ward clinicians give infected patients with the supportive care regime consist of oral medication, oral fluid rehydration, nutritional additives and physiological aid (Roddy et al, 2012).1.7 Conclusion.Ebola virus is considered as one of the most lethal virus found so far and it has extremely high mortality rate therefore according to the doctors and experts point of view anyone who has stayed in areas where Ebola outbreak have recently been reported should have knowledge about the symptoms of infection and seek medical advices at the first sign of illness. Many reasons are there for this highly lethal disease to be spread largely, the most important reason is hospitals lack medical equipment such as surgical gloves, masks and sodium thiosulfate syringes to inject medicines to patients and clean water and also the lack of high standard medical laboratories for the medical tests to done on the virus is also a major issue. The spread of knowledge about the Ebola virus is expected to solve another big part of the problem therefore prevention of a worldwide outbreak lies within the education of the virus, how Ebola victims can properly treated and by performing suitable action to isolate the virus before it has spread and maintaining hygienic conditions as much as possible.ReferencesBiek, R., Walsh, P.

Michael Jordan is Not God Essay -- essays research papers

Michael Jordan is one of the most well known people in the world. Whether its on the basketball court or on television, Michael Jordan is seen everywhere. Children see him and wanna be like Mike. Parents see him and intend hes the ideal role model. This is the person everyone sees and adores. However, nobody sees his character forth the court and off of television. I take that his off the court behavior shows his true self. Im not accusing Michael Jordan of being Satan I just take int believe he is the god that everyone makes him out to be.Everybody knows the story. Michael Jordan got cut from his high school basketball team so he worked twice as with child(p) and finally do it. People look at this and believe that hard work ethic will earn you success in whatever you do. He then went on to attend the University of North Carolina where he helped the Tar Heels become national champions. At this point people thought Michael Jordan was the real deal, but slightly were still skep tical. in the long run he was drafted into the NBA where he won six championship rings. No one was skeptical anymore. Everyone looks at his on the court success and believes he is the greatest actor to ever play the game. For those who dont watch sports, they see him on commercials and see him drink his Gatorade, wear his Hanes underwear, show off his tonic shoes, and spray his cologne.

Altered Reality in Joseph Conrads Heart of Darkness Essay example --

Altered Reality in sum of Darkness The world of darkness that Marlow finds himself in is instantaneously comparable to what Leary describes of the bardos (stages) that occur during a drug-induced trip or psychedelic experience. The underlying problem of the Second Bardo is that any and every shapehuman, divine, diabolical, heroic, evil, animal, thingwhich the human hit conjures up or the past flavour recalls, can present itself to consciousness shapes and forms and sounds whirling by endlessly (48). An example of such presentation is Marlows cognition of the jungle as a palpable force that has the power of human gestures. It calls, beckons, lures, etc. Leary writes that accompanying the moment of ego-loss is the perception of wave-energy flow the individual becomes aware that he is part of and surrounded by a charged field of energy, which seems almost electrical...the attempt to control or to rationalize this energy flow... is indicative of ego-activity and the First Bardo h igh quality is lost (41). Marlow never loses ego-activity so he never reaches transcendence, but his ego-activity rationalizes his feeling of the physical awareness of the jungle. He colors the Congo dark instead of demoralize and chooses to reject, not embrace, the force of the jungle so his rationalizations are negative and he thinks the force is evil. The negative, wrathful counterparts to this vision occur if the voyager reacts with fear to the powerful flow of life forms. Such a reaction is attributable to the cumulated result of game playing (karma) dominated by anger or stupidity. A nightmarish hell-world may ensue. The ocular forms appear like a confusing chaos of cheap, ugly dime-store objects, brassy, vulgar and useless. The ... ... all truth, and all sincerity, are just compressed into that inappreciable moment of magazine in which we step over the threshold of the invisible (Conrad, 113).

Human Genetic Screening :: Science Technology Papers

Human Genetic ScreeningHumans, like all told other living organisms, have genes. These genes instruct our bodies to subscribe proteins, these proteins are the molecules that determine the make for and function of each cell. Each gene or set of genes encode for the production of a particular protein.What is a gene ?The term gene was created by Wilhelm Johanssen, a Danish botanist in 1911. He was discussing social units of inheritance that Mendel called factors.T.H. Morgans studies on fruit fly genetics led to the idea of a gene as the smallest unit of recombination. Aggregated with this idea was another that said the gene was the unit of mutation, and another that the gene is the unit of function (the smallest unit of control over the phenotype ). modern evidence suggests that recombination net occur between any two nucleotide, which make the unit of recombination exactly unity and only(a) nucleotide long . Some mutations change only one nucleotide, so the unit of mutation c ould be only one nucleotide long . The unit of function is the cistron which is about 900-1500 nucleotide long. So we can identify the gene as the length of desoxyribonucleic acid that codes for one functional product (6). DNA of the human species carries more or less the alike(p) set of DNA with some variations . Variations in the DNA sequence can be neutral, others might have positive or negative influence. Genetic cover charge is testing of this variation (2). Human race carries 3000-4000 diseases in its genes, and it is important to acknowledge between genetical diseases and infectious diseases. Inherited diseases are caused by mutated genes which are inherited by an individual from his or her parents (2). The faulty gene will be one of the many healthy thousands of genes we possess in our cells. To pinpoint the location of these faulty genes, scientists search for variations in larger piece of DNA called markers, these subunits lie close on the DNA chain, and form the bas is of genetic screening. What is genetic screening ? The rationale of genetic screening is based on the binding of a try to the DNA molecule of the patient or the person to be screened. Complementary DNA nucleotide sequences bind to each other. The probe used is usually champion stranded DNA, which binds to the test sample. The DNA sample can be analyzed by a proficiency called restriction fragment polymorphism (RFLP). In this technique the DNA sample is combust up with a mixture of restriction enzymes which cut the DNA at a specific sequences.Human Genetic Screening Science Technology PapersHuman Genetic ScreeningHumans, like all other living organisms, have genes.
