- 1911: The Problem With Desertification
- ... to understand and accept. UNEP found that it lacked the focus necessary to bring about the implementation of the programs it recommended. The mechanisms created by UNCOD also failed to produce a increase in desertification control. Another reason UNED failed to achieve the PACD’s goals was due to the terminology of the document itself. The emphasis on desertification was never properly defined. The term desertification only created an image of ... preparedness and drought relief schemes, including self-help arrangements for drought- prone areas and the design of programs to cope with environmental refugees. 6) Encouraging and promoting popular participation and environmental education, focusing on desertification control and management of the effects of drought. There are many different cost effective strategies which the UNEP could use to assist developing countries. Because of the simplicity of these strategies, they are often overlooked when ... and are inexpensive enough to be worthy for consideration. These include the need for conservation to help natural vegetation regenerate. Also, there is need for better land management. We need to have better measure to control fires and more programs should be implemented that replace vegetation lost due to human carelessness and abandonment. Another promising type of desertification intervention is the development of science and technology. Technology holds an interesting ...
- 1912: The Race to the Moon
- ... on February 20, 1962. He and his Friendship 7 spacecraft gave Americans their first manned orbital flight. Three orbits were completed and nearly five hours were spent in space. Glenn took pictures and performed attitude-control and other chores during the flight. (Yenne 116-117). The National Aeronautics and Space Administration announced on December 7, 1961, a plan to extend the existing Mercury manned space flight program by the development of ... the zodiac, featuring the twin stars Castor and Pollux. (Gold 73). Gemini was an enlarged, redesigned spacecraft for two astronauts. Ten manned Gemini missions were flown from 1964 through 1966 to improve techniques of spacecraft control, rendezvous and docking, and extravehicular activity (space walking). One Gemini mission spent a record-breaking two weeks in space, enough time for a future crew to go to the Moon, explore, and return. (Yenne 118 ... All of the major objectives were met as well as many other objectives assigned to each mission, with the exception of land landing which was canceled from the Gemini Program in 1964. However, the precision control necessary to achieve the land landing objective was demonstrated. It demonstrated that pilots could live and work outside their ships. There were 12 Gemini space missions that followed the Mercury missions. This program was ...
- 1913: The Positive Effects of DDT
- ... over night. With DDT, the gypsy moth was virtually eliminated in the United States by the late 1950’s (Whelan 71). The low cost and effectiveness of DDT led to its later use in pest control in agriculture and forestry. In 1968, one pound of DDT cost 17.5 cents (Whelan 70). So effective was DDT that its use spread all over the world, controlling the population of insects and pests ... their war against malaria. In this capacity alone, DDT is responsible for saving at least 15 million lives (Helvarg 232). The myths about the dangers of DDT have been proven in this regard: regulation and control are necessary when dealing with any sort of chemical. Traces of DDT were found in the soil because the people who sprayed it used too much. And even the trivial amounts that were found in ... Cancer.” Cancer Weekly Plus. 10 Nov. 1997. Ray, Dixie Lee.

- 1914: Cloning
- Cloning In many controversial topics around the world, such as abortion, gun control, legalized drugs, the death penalty, and cloning (to name a few), we can find differing positions, and opinions. Many of these arguments, can be narrowed down to two different views, or constructs: individualistic and communitarian ...

The viewing end of the endoscope contains: (a) an eyepiece, with focus controls and camera attachment; (b) distal tip deflection controls, giving polydirectional control up to about 200o, plus locking capability; (c) objective lens control which may be a push-pull wire effecting focusing; (d) valve controls for air aspiration, (suctioned withdrawal of body fluids through the operations channel) and lens washing and air insufflation (application of water or ...
- 1916: Role of Government Intervention in Environmental Issues
- ... cases, a policy framework is sometimes more effective when there is less government intervention. As the level of government intervention diminishes, this allows more flexibility for corporations to achieve efficiency. Furthermore the traditional command and control approach has proven to be costly, bureaucratic and often inefficient. It is important to address the fact that there are numerous benefits that can be achieved for both policy makers and industries, if a policy ... to pay from polluting. Norm Miller also endorses this approach by stating that Rperformance-based approaches are more efficient, both for industry and for governmentS. Allowing a company to devise and manage their own pollution control plan is another effective (and Rde-regulativeS) approach. In the article, this was exemplified in an Arizona based company called Intel. Individual companies such as Intel knows what is best for the company. This means ... 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 pollution. There is also a possibility that this may lead to individualistic attitude. In a competitive market, everybody (or every corporation) tries to ...
- 1917: The Cause and Effects of Acid Mine Drainage
- ... are the exception because there are "very few aquatic plants known to be naturally tolerant to heavy metals.(Kelly 1988)" LAWS AND REGULATIONS Recently, many laws and regulations have been passed to help treat and control the acid mine drainage. The EPA has helped establish new limits and regulations such as no net acidity of drainage (pH between 6-9), average total iron content of discharge must be less than 3 ... and government agencies. President of the OSM, Robert Uram said, "Private organizations both grassroots and national have joined, in addition to government programs at the federal, state, and local levels." "The most effective way to control acid generation is to prevent its initiation.(Siwik 1989)" The biggest part of the reclamation and restoration is to research into the use of peat/wetland treatment for heavy metal removal from acid mine drainage ... world due to alot of industrialization and mining. This is not only a serious problem around the world, it touches home here, especially here in Appalachia, but it seems to be under or getting under control with all the new regulations and standards the EPA is setting. Low pH and a high acidity level is harmful to us our wildlife and our plants. With the help of more education and ...
- 1918: Frank J. Horgan Filtration Plant
- ... out the other way. The filter will now expand inside because of the pressure of the water. The waste will go to a separate place and then will be dumped to highland creek water pollution control plant for treatment and disposal of the waste. Employment It is required that at least two people are at all times in the plant. On the weekdays during 4-5 hours about 35 people work there. On week-ends and on holidays only two people are at the plant. The two required people are usually found in the control room. The people there have twelve hour shifts. If one person is late for work, the person duty is required to stay in the control room until they are relieved by the other person. Marketing We mostly pay water through maintenance fees or through utility bills. On average in North America, water costs about $1.30 American currency per ...
- 1919: Experiment to See if Soaking A Golf Ball Affects its Distance
- ... soaked in water? Independent Variable: My three different brands of golf balls. Dependent Variable: Will water seep in or not and if it seeps in will it have an effect on the golf balls distance. Control: My unsoaked golf balls. Reasearch: Per information sent to me by Titleist: Exposing a golf ball to water has a negative effect on the golf ball's performance. On average, after one week submerged in ... popular early pattern was the bramble, which featured raised round bumps in concentric circles. the first wound rubber ball was introduced in 1898. the three-piece Haskell was the first ball to mix distance and control. Cleveland entrepreneur Coburn Haskell, with Akron BFGoodrich engineer Bertram Work, wound continuous rubber thread under extreme tension around a small, solid rubber core, and wrapped the result in a gutta percha cover. Balata rubber soon ... The first two piece golf ball was introduced in 1968 by Robert Molitor a Spalding researcher who developed a ball consisting of a solid center with a tough thermoplastic cover. The two-piece ball sacrificed control for distance but has improved so much that today it represents 70% of all golf ball production. Interesting facts about dimples: Through my research I have found that even the slightest change in a ...
- 1920: Uranium: Nuclear Friend or Nuclear Foe
- ... reactor vessel. Although only a small amount of radioactive gas escaped, the financial damage to the utility was very large, $1 billion or more. An official investigation after the accident blamed operational error and inadequate control room design. This accident lead to far more strict building codes of nuclear reactors. The second of these incidents was perhaps the most famous and easily the world's worst reactor accident, it happened in a small town called Chernobyl in the former Soviet Union. On April 26, 1986, one of the four nuclear reactors at the plant went out of control. This malfunction was caused by a string of events. An improperly supervised experiment conducted with the water cooling system turned off led to the uncontrolled reaction, which in turn caused a steam explosion. The reactor ... is that not all nuclear waste can be incinerated. Another problem is the incinerated ashes must still be stored because they still contain radiation. The last and probably greatest problem of this method is the control of the radioactive gases created by incineration. 4. Sub-Seabed disposal: In this theory, spent uranium is buried under the seabed. An advantage of this over land disposal is that seabeds far from the ...
