Safety Devices in Car essays

Safety Devices in Car essays During a traffic crash, at the moment of impact, people in the car are still traveling at the car's original speed. Just after the car rapidly comes to a stop, the people not wearing seat belts slam into the steering wheel, windshield, or other parts of the car's interior, or are ejected from the car. Seat belts are very effective in reducing deaths and injuries caused in this second collision. The techniques of that is the seat belts use pre-crash tensioners. Within milliseconds, seat belt pre-tensioners tighten safety belts and help prevent belted occupants from sliding and bouncing around during a crash. The seat belts allow passenger to decelerate with the car during the collision instead head on collision with windshield or steering wheel. The seat belts also have a property to bend when crashing. So it increases time in impulse therefore decreases force impact on human. Inertia safety belt reels occurs approximately 6 milliseconds after full frontal impact. Approximately 4 milliseconds later before the head and chest begin to move forward, the air bag sensors trigger the front air bags and the small pyrotechnic charges in the pre-tensioners, which minimize any slack in the safety belt and negate the effects of bulky or layered clothing. The front air bags take approximately 35 milliseconds to fully inflate, which is completed just before the occupant meets the bag, approximately 50 milliseconds after impact. Between 45 and 70 milliseconds after impact, ensuring that the cross belt pressure against the occupants chest remains fairly constant. By avoiding peak loads, the potential for chest injury in very severe impacts is reduced. The function of inertia reel safety belts in effective, it can fasten you to the seat when crashing. The seat belt allows you to travel at the same speed with the car instead of throwing you out toward steering wheels, it can also trigger airbag to inflate. Inflating in a fraction of a seco...

The effect of inbreeding on natural selection in a seed-feeding beetle Article

The effect of inbreeding on natural selection in a seed-feeding beetle - Article Example The objective of the study is to understand whether offspring survival related to egg size is affected by inbreeding or not. To conduct the experiment beetle population was collected from Acacia gregii and bred in the laboratory for almost 12 generation before experimentation. Seed pods from both A. greggii and P.florida trees were used to fulfill the seeds requirement in the experiment and the seeds of the individual trees were thoroughly mixed to control seed coat variation among the seeds. Following the experimental design outbred females were mated with one sibling or non-sibling outbred male beetle after which the female laid their eggs on P.florida to record survival of all the offspring while A.greggii was used for rearing owing to the high rate of larval survival. These first generation adults when emerged from the seeds were used to create a second generation of both inbred and outbred offspring. The beetle pair was put in Petri dishes containing 20 seeds of P.florida and only one larva per seed was allowed to develop inside a chamber controlled at a temperature of 29-30 degrees. In the experimen t, 2-3 eggs were measured per Petri dish using a dissecting scope and finally 460 eggs from females mated to sibling males and 512 eggs from females mated to non-sibling males were collected. To illustrate the relation between the offspring survival and the size of the egg GAM model and linear probability models were used. The conclusive results showed that egg size did not differ much between females that were inbred and out bred; however, inbreeding vastly affected the survival rate. Eggs resulting from outbreeding survived more than those that were inbred. The values for egg to adult survival 0.66 in case of outbred offspring but a reduction of about 29.5% was seen in case of inbred ones. Linear probability model revealed that larva from larger eggs survived more than those emerging from smaller ones. It was evident from the logistic regression

Psychological Effects Of Long :: essays research papers

The Psychological Effects of an Injury   Ã‚  Ã‚  Ã‚  Ã‚  With every injury it is important to remember that the athlete will be affected mentally. Not all athletes will act identically to the same injury. Although research shows there are factors that are commonly seen among athletes going through adjustment to injury and rehabilitation. There are three reactive phases of the injury and rehab process. They are reaction to injury, reaction to rehabilitation, and reaction to return to competition or career termination. The reactions fall into four time frames: short term, long term, chronic, and termination.   Ã‚  Ã‚  Ã‚  Ã‚  In the scenario the athlete was diagnosed with a second degree ankle sprain. This would fall under the category of a long term injury. A long term injury is one where the rehabilitation time is longer than four weeks and may take up to a year. Some other examples of injuries in this category would be fractures, orthopedic and general surgeries, second and third degree sprain and strains, and debilitating injuries.   Ã‚  Ã‚  Ã‚  Ã‚  In the reaction to the injury itself, there is a primary reaction followed by a secondary reaction. With this ankle sprain, a common primary reaction is that of fear. This athlete can be afraid of many things ranging from them never getting better to never getting to play again to being afraid of the unknown. In order to conquer this fear the athletic trainer needs to help reassure the athlete about their injury. This can be done by presenting the truth about the injury and rehab process in a manner they can understand and gaining the athlete’s trust in the athletic trainer.   Ã‚  Ã‚  Ã‚  Ã‚  A common secondary reaction is anger. During this time the athlete may have an angry or hostile attitude and the person around the athlete at the time often takes the force of the anger. It is usually just a release for the athlete not a personal attack on the trainer.   Ã‚  Ã‚  Ã‚  Ã‚  This athlete will also have reactions to their rehabilitation. Loss of vigor and irrational thoughts are the primary reactions to long term rehab. The thing the trainer needs to be aware of at this point in time is that the loss of vigor can be masked as depression. The athlete experiencing loss of vigor will not have the same spirit as they usually do, but they will not have the common signs and symptoms of true depression. The athlete needs to understand that these feelings are normal as long as there are no signs of clinical depression.

Concept of Sustainble Development Essay

The tradition concept of development has for a considerable period of time been driven by economic considerations. Exploitation of natural resources which leads to environmental degradation motivated by targets of maximum profits has been the norm and little regard has been granted to the side effects of development initiatives. Gradual escalation of awareness and realisation of the range as well as the magnitude of environmental effects of development initiatives led to worldwide discussions on the way forward. Consequently, the concept sustainable development was conceived. However, this concept is perceived to be oxymoron by environmentalists, in other terms it is viewed as a combination of two contradicting terminologies. In view of the above, this essay endeavours to explain with relevant specific examples the reason why environmentalists consider the concept sustainable development as an oxymoron. In order to establish a good argument, two literature definitions of sustainable development shall be given. This will be followed by an explanation why sustainable development is considered to be oxymoron and this shall be supported by examples. And only after then shall a conclusion be stressed. According to the Ministry of Tourism, Environment and Natural Resources (2007: V) sustainable development is defined as, â€Å"development that meets the needs and aspirations of the present generation without causing deterioration and without compromising the ability to meet the needs of future generations†. On the other hand Todaro and Smith (2003) asserted that sustainable development entails both intra-generational and inter-generational equity. These concepts project a requirement of the present generation to meet their needs and aspirations without destroying the ability of the future generations to come and meet their needs and aspirations. As earlier alluded to, the concept s ustainable development is a mixture of two words with distinct opposing interpretations. According to Arend and Eureta (2002) sustainability entails the maintenance of the extraordinary diversity of plants, animals and insects that exist on earth. The other term development is known as a multidimensional phenomenon which has several aspects namely; economic, social, political, cultural and environmental. It is imperative to acknowledge the fact that true development involves a record of progress in all the dimensions of the development process. Furthermore, it is also necessary to be cognisant of the point that the environment and global systems which includes development are a series of dynamic and interconnected processes changing and interacting overtime, (Todaro and smith, 2003). From the definitions provided above, it is apparent that the two expressions sustainability and development contradict each other. This is due to the point that sustainability emphasizes on maintaining diversity and productivity of natural resources overtime. On the contrary, natural resources fuel the process of development; therefore, development cannot be a reality without consuming natural resources. The global community is hungry for development as a result people are constantly improving their livelihoods and welfare so as to attain higher standards of living through many innovations such as technology which in turn negatively impact on the environment. The question which maybe asked here is â€Å"what forms the basis of livelihoods?† (ECZ, 2008). According to ECZ (2000), the environment is the cornerstone of our livelihoods because biological resources are the primary sources of economic development thus development is all about consuming natural resources. Besides development, population dynamics also exert pressure on natural resources. With a clear reflection that development is all about the utilisation of natural resources, how then can sustainability be transformed into actuality? This is the question asked by many environmental practioners. It is evident through many global development initiatives how planetary natural resources are being utilized in order to achieve desired development targets. The two terminologies sustainability and development can be compared to a saying that says â€Å"two cobras cannot stay in the same mountain one has to die or eventually leave the mountain†. Therefore, sustainability and development are two cobras staying in the same mountain. The implication according to environmentalists is that, if we are to achieve ultimate sustainability then development should be out of the picture, (Energy Regulation Board, 2007). In Zambia, development programmes are using environmental resources at an increasing rate. With a fast growing population, the drive to meet goals set out in national development strategies and in international conventions, most recently defined in the Millennium Development Goals (MDGs), has likewise accelerat ed. As an example to illustrate the contradiction between sustainability and development, urbanisation in Chipata district can be utilized. As by definition, urbanisation may also mean development of land into residential, commercial and industrial properties. Urbanisation in Chipata has resulted in a number of negative environmental impacts which have adversely affected the diversity of biological resources. Consequential environmental effects include deforestation which has provoked excessive vegetative removal of tree cover along streams and on hills around Chipata town. Furthermore, land degradation due to urbanization is also prevalent in Chipata and this has led to soil erosion, sand and earth mining and degradation of catchment areas of Lunkhwakwa and Lutembwe rivers, (ECZ, 2008). Chipata district has over 56,000 hectors of land under protection and most areas are threatened by encroachment and deforestation due to urbanisation. Urbanisation in Chipata can be considered as progress from a developmental perspective because more houses, shops and industries have been erected and this has advanced people’s liv elihoods in terms of increased housing facilities and employment opportunities. However, this contradicts with sustainability because there has been excessive destruction of forests on the hills of Chipata which has resulted in extreme soil erosion down the slope, (ECZ, 2008). With reference to the economic dimension of the development process, the construction and expansion of mining as well as manufacturing industries can be perceived as progress. This is due to the fact that the existence of operational industries attracts various benefits to the local people. Firstly, job opportunities are created for the local and this helps them sustain their lives by acquiring wages at the end of each month. Salaries obtained by people from employment give them the ability to command their basic needs such as food, shelter and clothes, (MoFNP, 2006). The mining industry has played a pivotal role in the development of the country. However, the availability of exposed, accessible and near surface mineral deposits are increasingly becoming scarce requiring more expensive equipment to locate deeper buried ore deposits. This has led to gigantic environmental degradation due to the use of heavy sophisticated earth moving machines. For instance, when Konkola copper Mines (KCM) took over from Zambia Consolidated Copper Mines (ZCCM) on the copperbelt, Chingola and Chililabombwe in particular. After a while later, the production scale was upgraded and this created employment opportunities for over three thousand individuals who were unemployed, (MoFNP, 2006). Other benefits included improved infrastructure such as roads and schools as well as better health services. According to economists and development planners this was considered as national development because the lives of people were improved. However, the view of economists and development planners contradict with that of environmentalists because an elevation in the production scale of any industry is problematic as far as environmental sustainability is concerned because of unsustainable production strategies that hamper a good quality of life, (ECZ, 2011). According to ECZ (2008) mining activities especially large-scale open pit mining has negatively affected the environment resulting into environmental degradation. Among the prominent open pit mines are Nchanga, Kansanshi and Maamba collieries. Despite development enhanced by these mines, industrial operations of these sites have caused the contamination of terrestrial ecosystems mostly ascribed to dust fall-out and this has been a draw back as far as the maintenance of biological resources diversity and productivity are concerned. Kafue River on the copperbelt was polluted by Konkola copper Mines Plc due to toxic substances which were discharged into the water body. This occurrence negatively affected marine ecosystems which resulted in a depletion of certain species. Water resources have been affected by climate change and other factors such as increase in population growth, industry and agriculture which are induced by development. Unfortunately, there has been no corresponding expansion of sewerage infrastructure and solid waste disposal facilities and most of them are in a poor state, despite the increasing rate of development and this actually curbs sustainability. However, it must be realized that only after the last tree has been cut, only after the last river has been poisoned, only after the last fish has been caught only then will it be discovered that money cannot be eaten, (ECZ, 2008). Human sustainability has also been affected due to the side effects of development which have made the environment unsafe to support a good quality of life. The rate at which development is happening has put so much pressure on the environment and this has resulted into various environmental issues such as air pollution, water pollution, land pollution and ozone layer depletion among others. Environmentalists have identified that increasing industrial operations in Zambia have negatively influenced life expectancy and infant mortality rate. For example, adult survivorship levels have been declining in the last twenty years following rapid development trends. Life expectancy for females dropped from 46 years in 1980 to 44 years and 29 years in 2000. In the same category for males it was 44 years in 1980, 42 years in 1990 and 23 years in 2000. Diseases associated with environmental degradation include malaria, tuberculosis, asthma, bronchitis and dysentery among others and these so far have claimed quite a considerable number of lives, (MoFNP, 2006). In conclusion, it can be said that development and sustainability are two ends of the same continuum. Whichever example of development one might think of such as industrialization and housing, they are unsustainable, unless that development is related to green technologies or meant to counter the adverse effectives of development. In the end, the solution is a compromise because people need sustainability but cannot progress without development, hence, sustainable development. We can have development as long as we put measures in place to minimise environment damage. These measures include environmental impact assessments, environmental audits and strategic environmental assessments among others, hereafter ensuring sustainability. REFERENCES Arend. H and Eureta.
