Environmental acoustics Essay

The research from various part of the world has been able to reveal that approximately 80 million people are exposed to unacceptable high noise levels particularly, the noise emitted from road/tyre. Thus, noise sources that affect people is mostly from road traffic noise, which is by far the most pervasive. In UK for example, over 90% of the population hear traffic noise directly from home while 10% consider noise highly annoying. Thus to reduce the annoying traffic noise, it is mandatory to consider the method of reducing the sources of noise by improving the tyres and road surfaces. While various measures have been adopted in reducing the propagation of noise in the sensitive areas, all of these measures have been note to play a vital part in achieving an acceptable acoustical environment for people living near to roads. Although, in the attempt to control noise on the road surface, there is need to study the noise generated by the tyre/road interaction. Most researches conducted have been revealed that Tyre/road surface interaction noise tends to dominate at moderate and high road speeds. Thus, to control the vehicles noise, there have been various encouragements to encourage innovation and to reflect the improvements made in vehicle design. However, the progress has been quite slower concerning the tyre noise, thus it was only in recent time that there that control for tyre noise has been introduced in the EU Directive of 2001/43/EC. The directive has established a test method for the type approval of tyres with respect to noise emissions and limit values for different types of tyre. Thus, to measure the road/tyre noise emission, this paper will focus on the noise emitted from different types on different road surface. The first part of the paper will focus on the introduction. Moreover, the methodology used in carrying out the test of tyre/road noise emission will be extensively analysed in this paper. Furthermore, the result of the test will also be made available in the research paper. Finally, conclusion and recommendation for the effective methods of reducing the noise pollution from the tyre/road surface will be focused. ( Environmental Research 2004)

He wanted the fastest cow, the roundest pigs, the juiciest melons, the sweetest sugar, the finest silk, and the purest of silver and gold. He took everything, his people were the poorest and saddest. No one disobeyed him because he had the fiercest soldiers that had the sharpest spears.

Do Humans behave to maximise R essays

Do Humans behave to maximise R essays The first part of this title that we need to address is what is reproductive success? I feel that it can either be the amount of offspring that your genes are passed onto, or ensuring that the offspring you do have enjoy a good upbringing with plenty of resources. This is seen in many species where optimal clutch size is a major factor. However if it is difficult to say whether humans behave in this manner due to such events as the demographic transition which I will talk about later. Humans seem to behave very differently to other species within the animal kingdom. The basis of clutch size for most species is the amount of resources available. For example during a baron patch where food may be scarce some species will have a smaller clutch size to ensure survival of some of their offspring, this is also true the other way round. However humans are not going with his trend at the moment. I f we look at modern day Britain resources are more plentiful than ever before, however the birth rate is also the lowest it has been at just 1.8 children per couple. That particular statistic is amazing as it means many couples are passing on fewer genes than they own. What I mean by this is that a child possesses half of each of his parents genes, so a minimum of two children are needed to ensure that you are genetically replaced. If we look at this and put it to my first answer to my question what is reproductive success? Then the answer to the title would have to be no. As modern day humans are not passing on a sufficient amount of genes to replace themselves in the gene pool. The hypothesis that explains this explains that perhaps humans would prefer to ensure their children achieve in this would by giving a smaller amount of children more attention, and therefore more resources. This would allow the children to have a potentially more successful life which would mean there being more chance of your genes staying in ...

Healthy Eating Messages and Children Nutrition (Case Study) Essay

Healthy Eating Messages and Children Nutrition (Case Study) - Essay Example As Gorn et al. (1982, 200) found ‘television advertising for children is developed from direct testing and observation of the child audience; Children are subjected to research techniques developed for the study of child psychology to determine the most effective way of inducing their counterparts in the nationwide audience to demand advertised products’. Under this intensive observation, the advertising addressed to children manages to achieve the target set by the multinational corporations, i.e. the ‘cultivation’ of specific nutritional preferences to children of all ages in accordance with the production line of these firms. In the same context, Smitt et al. (2007, 57) stated that ‘the issues of food advertisements, especially aimed at children, and food labeling are factors behind the obesity epidemic which need to be tackled while commercial communication increases consumer information; however, the promotion of unhealthy foods negatively impacts the health of the population and for this reason actions need to be taken to protect children from commercial activity in this field’. The above assumptions are in accordance with the findings of WHO in 2003 which indicate that ‘dietary adjustments may not only influence present health, but may determine whether or not an individual will develop such diseases as cancer, cardiovascular disease and diabetes much later in life’ (WHO, 2003, 2). In fact it has been found that wrong nutritional ‘habits’ can lead to severe consequences for the health not only in adults but also in children. More specifically, a research made by the World Health Organization in 2003 showed that ‘higher blood pressure in childhood (in combination with other risk factors) causes target organ and anatomical changes that are associated with cardiovascular risk, including reduction in artery elasticity, increased ventricular size and mass, haemodynamic increase in

MEDIA Essay Example | Topics and Well Written Essays - 500 words

MEDIA - Essay Example The audience tends to be neglectful of the wrong aspects of their behavior and approves of the behavioral model as such. Particularly, the youth blindly follows the role models. Media frequently highlights the negative aspects of the celebrities and often reveals the hidden controversies about them, which in turn causes the society to blindly imitate them (Oak). Although the controversies are projected with a view to create awareness in the people regarding what is happening around them. Paradoxically, this attempt is in turn generating more negativity in public. Media increases violence in the society: Media often becomes a good source of unique and innovative ideas for the pick pockets, thieves and robbers. Quite often, plays are based upon new ways of carrying out violence in the society, which potentially add to the skills and knowledge of the violence makers more than they educate the sufferers. In addition to that, media plays the role of slow poison for the society. Originally , people used to be very irritated by acts of violence, and used to protest against them in any way they could. With the passage of time, people have become immune towards the widespread violence in the society.
