Animal Farm, 1984 Essays -- Animal Farm Essays

Animal farm and 1984 Napoleon, the leader of all the animals of the Rebellion, can be compared and contrasted with Big Brother, the leader of all the people of 1984. Both Big Brother and Napoleon show the qualities of a cruel ruler. Similar to Big Brother, Napoleon is a secretive plotter who works behind the scenes rather than openly. However, unlike Napoleon, Big Brother periodically appears on the television screen. Napoleon and Big Brother both work continually to weaken their rivals, whether it is by removing Snowball or eliminate Rutherford. Both place importance on complicated ceremonies and parades to prevent their workers from thinking about their schemes. Napoleon’s control over animal farm is not as powerful as Big Brother's control over the workers in 1984 (Oceania). In the service of their ruler, Squealer and Winston both revise history. Winston's task at the Ministry of Truth is to alter the past to suit the present. Squealer's duty is to amend the Seven Commandments also to suit the present. However, Squealer supports the views and beliefs of Napolean wheras Winston does not support the rules of Big Brother. Parson and Boxer are both characterized by their willingness to work, constantly volunteering for work whenever something needed to be done. Boxer worked constantly to build the windmill and Parson worked endlessly organizing marches and parades. Preparation for Hate Week was described a "Processions, meetings, military parades, lectures, film shows,...

The Non Dredged Reclamation Method Environmental Sciences Essay

With the rapid economic and population growing, assorted economic, societal, lodging and conveyance demands of the community are increasing, ensuing in increasing demand for land supply. Due to the limited land supply, renewal is normally used to undertake the job in Hong Kong. However, renewal does non merely lend to the economic development but besides the environmental debasement. In this essay, jobs caused by renewal and possible solutions will be discussed. As mentioned in Environmental Impact Assessment Report ( 2001 ) , dredging, disposal of Marine clay and majority filling activities may give rise to many possible impacts on H2O quality. First, solids may be suspended in the H2O column. Second, as clay moving ridges and turbulent flow will be generated, by perturbation, organic and inorganic substances e.g. ammonium hydroxide, heavy metals and sulfides may be released into the H2O column. Third, during the compacting and settling procedure in site formation, contaminations and leachate may be given out from pore H2O and deposits severally. As a consequence, the marine H2O quality will be deteriorated. 2.2 Marine ecosystem Harmonizing to Chan ( 2000 ) , dredging and disposal of waste involved in renewal will convey inauspicious effects to the marine ecosystem. First, remotion of deposit may take to the loss of home ground. Second, marine beings may entrain during dredging. Third, dissolved O will be depleted and foods will be released into the H2O. In peculiar, if there is a important rise in the alimentary degree, algal productiveness will increase which may ensue in & A ; acirc ; ˆ?red tides & A ; acirc ; ˆA? . 2.3 Air quality The job of air pollution will originate during the operation period of renewal as a big sum of dust will be emitted where the & A ; acirc ; ˆ?dust & A ; acirc ; ˆA? here refers to general suspended particulates. Among assorted sorts of beginnings of air pollution, earthmoving ( lading, droping and bulldozing ) , haul route traffic on unpaved roads and wind eroding of the unfastened site country lower the air quality the most ( Chan, 2000 ) . Solutions 3.1 The non-dredged renewal method Traditionally, the soft Marine clay in the ocean floor is replaced by sand fill to do a strong foundation for seawall building. Dredging and disposing of Marine clay are therefore involved. As the dredging procedure in renewal is the cardinal cause for the environmental impacts mentioned above, the non-dredged renewal method is advocated for the future renewal undertakings. Making mention to Hong Kong-Zhuhai-Macau Bridge Hong Kong Projects ( 2011 ) , this renewal method does non necessitate dredging the soft Marine clay in the ocean floor before backfilling. Alternatively, inert building and destruction stuff is used to make full many big interlocked steel cells. The steel cells will so drop in the H2O and remain on the alluvial sediment, organizing the margin wall. ( Items, 2011 ) As found in Items ( 2011 ) , the non-dredge renewal has many benefits over the conventional dredge breakwater building method. For case, dredging and dumping of Marine clay can be about wholly avoided. Besides, merely 30 % of the original suspended atoms will be released during renewal and merely half of the backfilling stuff will be needed. Thus the building Marine traffic can be decreased by about 50 % . It can be concluded that the non-dredge renewal method will convey less environmental impacts and therefore it is a better pick for renewal. 3.2 Development of belowground infinite Enhanced usage of belowground infinite is an effectual and executable option to increase land supply as Hong Kong is cragged and abundant with strong volcanic and flinty stones. This geographic characteristic favors the development of belowground infinite in Hong Kong. Rock caverns can be developed for assorted land utilizations such as crematory, substation, sewerage intervention installations etc ( Hong Kong Underground Space Study Executive Summary, 2009 ) . While both steps can alleviate the job of deficiency of available land, developing belowground infinite has some advantages over renewal. For illustration, some unwanted utilizations like garbage aggregation point can be built underground so that the impacts on the occupants populating nearby can be minimised. Furthermore, developing belowground infinite does non do much pollution or take away natural resources, which means that the natural environment can be preserved. Decision Though renewal can supply for the demands of the economic development, the conventional renewal method causes H2O pollution, air pollution and adversely affects the marine ecosystem, which is non an ideal act for the society. In order to strike a balance between economic growing and environmental preservation, the non-dredged renewal method should be adopted for future renewal undertakings as it is more environmentally friendly. In add-on to renewal, development of belowground infinite should be considered which can move as an option to increase land supply and reserve our valuable seaport.

Chernobyl Nuclear Disaster, 1986

At 1:23 a.m. on April 26th, 1986, reactor four at the nuclear power plant near Chernobyl, Ukraine exploded, releasing more than a hundred times the radiation of the bombs dropped on Hiroshima and Nagasaki. Thirty-one people died shortly after the explosion and thousands more are expected to die from the long-term effects of radiation. The Chernobyl nuclear disaster dramatically changed the worlds opinion about using nuclear reaction for power. The Chernobyl Nuclear Power Plant The Chernobyl nuclear power plant was built in the wooded marshlands of northern Ukraine, approximately 80 miles north of Kiev. Its first reactor went online in 1977, the second in 1978, third in 1981, and fourth in 1983; two more were planned for construction. A small town, Pripyat, was also built near the Chernobyl nuclear power plant to house the workers and their families. Routine Maintenance and a Test on Reactor Four On April 25, 1986, reactor four was going to be shut down for some routine maintenance. During the shutdown, technicians were also going to run a test. The test was to determine whether, in case of a power outage, the turbines could produce enough energy to keep the cooling system running until the backup generators came online. The shutdown and test began at 1 a.m. on April 25th. To get accurate results from the test, the operators turned off several of the safety systems, which turned out to be a disastrous decision. In the middle of the test, the shutdown had to be delayed nine hours because of a high demand for power in Kiev. The shutdown and test continued again at 11:10 p.m. on the night of April 25th. A Major Problem Just after 1 a.m. on April 26th, 1986, the reactors power dropped suddenly, causing a potentially dangerous situation. The operators tried to compensate for the low power but the reactor went out of control. If the safety systems had remained on, they would have fixed the problem; however, they were not. The reactor exploded at 1:23 a.m. The World Discovers the Meltdown The world discovered the accident two days later, on April 28th, when operators of the Swedish Forsmark nuclear power plant in Stockholm registered unusually high radiation levels near their plant. When other plants around Europe began to register similar high radiation readings, they contacted the Soviet Union to find out what had happened. The Soviets denied any knowledge about a nuclear disaster until 9 p.m. on April 28th, when they announced to the world that one of the reactors had been damaged. Attempts to Clean Up While trying to keep the nuclear disaster a secret, the Soviets were also trying to clean it up. At first they poured water on the many fires, then they tried to put them out with sand and lead and then nitrogen. It took nearly two weeks to put the fires out. Citizens in the nearby towns were told to stay indoors. Pripyat was evacuated on April 27th, the day after the disaster had begun; the town of Chernobyl wasnt evacuated until May 2, six days after the explosion. Physical clean-up of the area continued. Contaminated topsoil was placed into sealed barrels and radiated water contained. Soviet engineers also encased the remains of the fourth reactor in a large, concrete sarcophagus to prevent additional radiation leakage. The sarcophagus, constructed quickly and in dangerous conditions, had already begun to crumble by 1997. An international consortium has begun plans to create a containment unit that will be placed over the current sarcophagus. Death Toll From the Chernobyl Disaster Thirty-one people died shortly after the explosion; however, thousands of others who were exposed to high levels of radiation will suffer serious health effects, including cancers, cataracts, and cardiovascular disease.
