- 751: Charles Darwin And Richard Owen
- ... is not applicable for every species. Darwin noticing this, responded by stating the following in Chapter V of his Origin of Species : Several years ago I was much struck by a remark, to the above effect made by a remark, to the above effect, made by Mr. Waterhouse. Professor Owen, also, seems to have come to a nearly similar conclusion. It is hopeless to attempt to convince any one of the truth of the above proposition without giving the ...
- 752: Time Machine Book Report
- ... salt Dead Sea, the stony beach crawling with these foul, slow-stirring monsters, the uniform poisonous-looking green of the lichenous plants, the thin air that hurt one's lungs; all contributed to an appalling effect (69). This scene is one of complete desolation and despair. He had spent all his time making the time machine to see the wonderful advances in technology, knowledge, and intellect. Instead he finds only decay ... the reader. It was about a scientist, Griffin, who's goal is to make living tissue transparent. He makes a formula that can make a human invisible, with no clothes on, for it has no effect on fibers. Wells implies, here, that in the future, a person could actually create an army of invisible men. With all the focus of war in Europe in this time frame, war and new inventions ...
- 753: The Computer Revolution
- ... At first huge computer systems were solely the reserve of companies such as IBM and ICI who used their hugely expensive machines for payroll because processor power as very limited. This had an almost immediate effect as the number of people employed in these roles in these larger companies was dramatically reduced. However society at large did not observe any real changes, as the number of people employed in the larger ... Automated Teller Machine) on your high street or supermarket and everywhere accepts credit cards. This is due to the improvements in the IT infrastructure which surrounds these transactions, i.e. Communications, processing power etc. The effect of the pervasion of this technology has been widely felt throughout this country and the world. Despite the huge rise in the number of bank accounts and investments over the last twenty years, the number ...
- 754: Antibiotic Resistance 2
- ... responsive only to vancomycin. Because vancomycin-resistant E. faecalis has become quite common, public health experts fear that it will soon deliver strong vancomycin resistance to those S. aureus strains, making them incurable. The bystander effect has also enabled multidrug-resistant strains of Acinetobacter and Xanthomonas to emerge and become agents of potentially fatal blood-borne infections in hospitalized patients. These formerly innocuous microbes were virtually unheard of just five years ... If many patients in a hospital ward were being given a particular antibiotic, this high density of use would strongly select for bacterial strains unsubmissive to that drug and would eliminate susceptible strains. The ecological effect on the ward would be broader than if the total amount of the antibiotic were divided among just a few people. If physicians considered the effects beyond their individual patients, they might decide to prescribe ...
- 755: Temagami
- ... of Natural Resources, 1991 The History of the Forest Forests have long been recognized as having vast power, both through their potential and how it has been viewed by humans, as well as through their effect on humans in sometimes subtle ways. The inherent properties of wood have always made it attractive as a versatile resource but there are other, more subtle ways in which it affects people. The tropical rainforests ... from turning to wasteland - one has only to look at ancient nations such as Mesopotamia, once a heavy agricultural area and now a vast desert, or the ever expanding Sahara desert to see the devestating effect of soil erosion. (CAN ENCYC) After a time, people began to understand this, at least in a crude sense. Forestry, it seemed, must be more than simply cutting down trees. The forests must also be ...
- 756: Role of Government Intervention in Environmental Issues
- ... permit approach. Under this model corporations are able to buy, sell and trade permits that legally allows emission. Many economists have favored this approach because this also provides incentives for technical improvement. So the aggregate effect would be that most industries would try to maximize their profits by trying to come up with new techniques to reduce the level of emission. This in turn would allow them to reduce the cost ... is still a notion of Ryou can pollute as long as you can pay for itS. So if a great number of corporations are financially able to pay for their level of emission, the aggregate effect on our environment would be devastating. Under this model, it is also difficult to penalize the polluters. Where as under the command and control approach, severe fine or even imprisonment can be imposed to prevent ...
- 757: Ku Klux Klan 4
- ... flag. They then stood up a sixteen foot long cross and burned it. One week later, this group applied for a state charter making it "The Knights of the KKK, Inc." This was put in effect during the Reconstruction. The new Klan at first received little attention. Only in time, it became the biggest and most powerful Klan in history. Klan membership was limited to native-born, white, Protestant American Men ... example, in the 1970s and 1980s, whites began to worry about losing their jobs, and special programs were being set up for blacks, and this concern led to new Klan activity which is still in effect today. Today in the Klan there are approximately 10,000 Klan members. (World Book Encyclopedia J-K, 310) In conclusion, the Klan has formed and diminished many times in the past. If the Klan tries ...
- 758: Radio: A Form of Communication
- ... crystalline substance that vibrates at a natural resonant frequency when it is supplied with energy. This resonant frequency depends on its thickness and the manner in which it is cut. By means of the piezoelectric effect, the vibrations are transformed into a small alternating voltage having the same frequency. After being amplified several thousand times, this voltage becomes the radio-frequency carrier. The manner in which this carrier is used depends ... the IF amplifiers. The prime advantage of FM, in addition to its fidelity, is its immunity to electrical noise. Lightning storms superimpose noise on an AM signal by increasing the amplitude of the signal. This effect shows up in a receiver as a crackling noise. An FM receiver, because it decodes only the frequency variations, has a limiter circuit that restricts any amplitude variations that may result from added noise. Single ...
- 759: Anabolic Steroids
- ... more androgenic than anabolic so they can very depending on the drug. Androgenic is the precursor of the male characteristics of muscle size and strength, deeper voices, body hair, sex drive, and aggressiveness. Another side effect is gynocemastia. Gynecomastia is also referred to as bitch tits. This is the abnormal breast like tissue, which can develop in males using large doses of steroids. This is also naturally occurring in some men ... a weak immune system. If a person uses steroids and does not choose the correct one, administer the correct dosages, train correctly, eat correctly, and get enough rest, the steroids will have little, if any, effect. Only the ignorant believe that drugs alone can create the physique and physical performances of one's goal. A lot of hard work and self discipline is necessary to get the most out of using ...
- 760: William Gibson and The Internet
- ... line between the made and the born is being blurred; machines are becoming biological and the biological is being engineered. The reason is that we have reached the limits of industrial thinking. Linear cause and effect logic is no good for figuring out the hugely complex systems (phone networks, global economies, the Internet) that we have created, so we've begun to look instead at natural systems. After years of tapping ... to consider". eorge Gilder of the Hudson institute stated "there is about to be a revolution, born of nothing less than sand, glass and air, and yet it was one which would have an incalcuble effect upon us all. From sand will come microchips offering super computing power on slices of silicon smaller than a thumbnail and cheaper than a book. From glass will be fashioned fibre-optic cables that will ...
