... mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associated with the presence of certain pollutants. Findings from such studies include: reproductive disruption in starfish due to PCBs, bird eggshell thin ...
... presence of a quarry restrict the choice for further development? Could an integrated approach be adopted and a 2nd generation quarry planned? The decision of whether or not to go ahead cannot be delayed indefinitely as Norway and Spain are looking at developing their own. If it is to go ahead then an early start will give Harris a stronger position in the market. 2 INTRODUCTION This report examines the controversy and key issues surrounding the superquarry at Rodel, Lingerbay on the southern coast of the Isle of Harris (Figure 1) and attempts to find an acceptable solution. The quarry will hollow out the heart of the mountain but leave enough of a shell to ...
... NASA selected seven to become U.S. astronauts. There names, Lieutenant M. Scott Carpenter; Air Force Captains L. Gordon Cooper, Jr., Virgil “ Gus” Grissom, and Donald K. “Deke” Slayton; Marine Lieutenant Colonel John H. Glenn, Jr.; and Navy Lieutenant commanders Walter M. Schirra, Jr., and Alan B. Shepard, Jr. Of these, all flew in Project Mercury except Deke Slayton who was grounded for medical reasons. He later became an American crewmember of the Apollo-Soyuz Test Project. The Mercury module was a bell shaped craft. Its base measured exactly 74.5 inches wide and it was nine feet tall. For its boosters NASA chose two U.S. military rockets: th ...
... world's rainforests is lost each year. Unless we change this amount of deforestation, there will be little of our rainforests left in 50 years. Our rainforests are an integral part in our world's ecosystem, and therefore need to be conserved as best we can. The rainforests provide safety and life to millions of kinds of life, they may contain cures to many of the world's diseases, and they provide over 60 percent of the world's supply oxygen to humans and other animals. Destroying these beautiful and key parts of the world would be catastrophic to mankind. There are many ways in which we can conserve our natural rainforests, and thus partly ensure our survival ...
... and eye and ear anomalies. [2,4,15,16] Even in the absence of growth retardation or congenital abnormalities, children born to women who drank alcohol excessively during pregnancy appear to be at increased risk for attention deficit disorders with hyperactivity, fine-motor impairment, and clumsiness as well as more subtle delays in motor performance and speech disorders. [4] These findings have been referred to as fetal alcohol effects (FAE). As recently described, FAS and FAE produce profound cognitive, behavioral, and psychosocial problems that persist to date of follow-up of those affected. In the most comprehensive and far-reaching study to date, Streissguth ...
... of life. It is an attribute characterized by sensation and voluntary movement which described the difference between normal waking state of animals and men and their condition when asleep.2 Other descriptions included an analysis of consciousness as a form of relationship or act of the mind toward objects in nature, and a view that consciousness was a continuous field or stream of essentially mental "sense data." The method believed by most early writers in determining consciousness was introspection—looking within one’s own mind to discover the laws of it’s operation. This belief was limited when it was apparent when observationalists could not agree on ...
... the benefits. Alternative sources of energy are making their way into the highly competitive field of electricity production. With the wealth of sources such as solar, wind, hydro or geothermal the dangers involved with fission could be solved by adopting these newer, safer methods. A main source of energy that could lead the way for the near future is solar energy. It is clean efficient and is already a large part of American and Canadian electricity production. "Solar energy already supplies about 6% of the nation's [U.S.A] energy ... the industry is still in an embryonic stage, and opportunity exists for increasing this contribution by ten times from curren ...
... well be 10 billion people on earth before the middle of the next century. Even more significant, on an ecological level, is the rise in per capita energy and material consumption which, in the last 40 years, has soared faster than the human population. “An irresistible economy seems to be on a collision course with an immovable ecosphere.” Based on these facts alone, there is grave reason for concern. Taken further, it is even more frightening to note that, while man has affected the environment throughout his stay on earth, the impact has been most intense in the relatively short industrial era. Since the industrial revolution, and over the past cent ...
... normal chromosomes of 46, and some affected ones with 47. Translocation occurs when part of the twenty-first chromosome breaks off and attaches to another cell. The total number of chromosomes is 46, however the excess material from the twenty-first chromosome results in the affects of the syndrome. With translocation, most cases occur sporadically, with no bearing on maternal age. These two types of this syndrome are very rare, being responsible for only 6 or 7 percent of all cases. Children with Down syndrome are at high risk for health problems. These include congenital heart defects, respiratory problems, increased suseptibility to infections, ...
... has gone too far. At the University of Alabama, a short-term research has been done on 150 people on the effect of the intake of salt related to high blood pressure. Result shows that those with normal blood pressure experience no change at all when placed in a extremely low salt diet, or later when salt was introduced, Of the hypertensive subjects, half of those on the low salt diet did experience a drop in blood pressure, which returned to its previous leel when salt was introduced. Of course, these are other researcherswhgich tend to support the findings. A small Indiana study showed that when normal individuals took large amount of salt, the bolld pr ...
