Heart Of Dark Essays - Joseph Conrad, Congo Free State,

Heart Of Dark In Joseph Conrad's book Heart of Darkness the Europeans are cut off from civilization, overtaken by greed, exploitation, and material interests from his own kind. Conrad develops themes of personal power, individual responsibility, and social justice. His book has all the trappings of the conventional adventure tale - mystery, exotic setting, escape, suspense, unexpected attack. The book is a record of things seen and done by Conrad while in the Belgian Congo. Conrad uses Marlow, the main character in the book, as a narrator so he himself can enter the story and tell it out of his own philosophical mind. Conrad's voyages to the Atlantic and Pacific, and the coasts of Seas of the East brought contrasts of novelty and exotic discovery. By the time Conrad took his harrowing journey into the Congo in 1890, reality had become unconditional. The African venture figured as his descent into hell. He returned ravaged by the illness and mental disruption which undermined his health for the rem aining years of his life. Marlow's journey into the Congo, like Conrad's journey, was also meaningful. Marlow experienced the violent threat of nature, the insensibility of reality, and the moral darkness. We have noticed that important motives in Heart of Darkness connect the white men with the Africans. Conrad knew that the white men who come to Africa professing to bring progress and light to darkest Africa have themselves been deprived of the sanctions of their European social orders; they also have been alienated from the old tribal ways. Thrown upon their own inner spiritual

Business Strategy Coursework Assignment 2006 Essays

Business Strategy Coursework Assignment 2006 Essays Business Strategy Coursework Assignment 2006 Essay Business Strategy Coursework Assignment 2006 Essay Business Strategy Coursework Assignment 2006 / 2007 Analyse the schemes used by Lush UK to construct and prolong competitory advantage. What are the strategic issues and options confronting the administration in November 2006? The first strategic issue would be to increase the board members so that the board is independent, with a Non-executive Chairman and four Non-executive Directors. Recruit or promote or train and advance one or two proficient specializers, from within the administration, with one to be the future CEO and the other to run R A ; D. Besides appoint Marketing and Finance Directors. The Executive Directors being the CEO, FD and Marketing Director should be responsible for looking after the operations: Chief Executive Officer – UK Operations Finance Director – Finance and Canadian and Italian Operationss Marketing Director – Marketing and Australian and Nipponese Operationss The 2nd strategic issue will be to pull up a household tree of the administration to demo who runs each store and each operation. That’s the Board and the Management squad with Team Leaders and Team members. Note: TBA = To Be Advised and Shops need to be defined by Regional Manager and Country. The 3rd strategic issue, since the company exports to 29 states do they hold web sites, packaging and cusps that cover the linguistic communications of all these states. The 4th strategic issue would be for the Board to so carry on a reappraisal and study all the employees and clients for their positions on how things could be improved. The last five old ages of their rivals Annual Reports should be included in this reappraisal and all thoughts and new merchandises listed and scored as a possible merchandise or thought to better a merchandise scope, packing or selling. This will ensue in the route map for the future way of the administration.

Nitrogen Recovery in WasteWater Treatment Term Paper

Nitrogen Recovery in WasteWater Treatment - Term Paper Example Nitrogen in domestic wastewater consists of approximately 60 to 70 percent ammonia?nitrogen and 30 to 40 percent organic nitrogen (Tchobanoglous et al. 2003; Crites and Tchobanoglous 1998). Environmental Effects Health Effects from Drinking Groundwater Contaminated with Nitrates- Human health concerns from nitrates in groundwater used as a drinking water source primarily focus on methemoglobinemia, however some studies suggest that nitrates may increase the risk of birth defects and development of certain cancers in adults. Surface Water Pollution with Nitrogen- The harmful effects of eutrophication due to excessive nitrogen concentrations in the aquatic environment have been well documented. Algae and phytoplankton growth can be accelerated by higher concentrations of nutrients, leading to harmful algal blooms, hypoxia, and loss of submerged aquatic vegetation (SAV). In addition to stimulating eutrophication, nitrogen in the form of ammonia can exert a direct demand on dissolved oxy gen (DO) and can be toxic to aquatic life. Even if a wastewater treatment plant (WWTP) converts ammonia to nitrate by a biological nitrification process, the resultant nitrate can stimulate algae and phytoplankton growth. Removal of nitrogen from wastewater is a complex process, even for large wastewater treatment plants. Quality control of nitrogen removal processes from individual onsite wastewater systems is even more difficult to manage. Most of the nitrogen is released as nitrate (NO3-), which is highly mobile in the soil water. Wastewater treatment has generally been defined as containing one or more of the following four processes: (1) preliminary, (2) primary, (3) secondary, and (4) advanced (or tertiary) treatment. Preliminary treatment consists of grit removal, which removes dense inert particles, and screening to remove rags and other large debris. Primary treatment involves gravity settling tanks to remove settleable solids, including settleable organic solids. The perfo rmance of primary settling tanks can be enhanced by adding chemicals to capture and flocculate smaller solid particles for the precipitation and removal of phosphorus. Secondary treatment follows primary treatment in most plants and employs biological processes to remove colloidal and soluble organic matter. EPA classifies advanced treatment as â€Å"a level of treatment that is more stringent than secondary or produces a significant reduction in conventional, non?conventional, or toxic pollutants present in the wastewater† (U.S. Public Health Service and USEPA 2008). Effluent filtration and nutrient removal are the most common advanced treatment processes. Nitrogen Removal Processes The biological removal of nitrogen is carried out through a three-step process: (1) the conversion of ammonia from organic nitrogen by hydrolysis and microbial activities, called ammonification; (2) the aerobic conversion of ammonia to nitrate by reacting the ammonia with oxygen in a process call ed nitrification; and (3) the conversion of nitrate to nitrogen gas by reacting the nitrate with organic carbon under anoxic conditions in a process called denitrification. The nitrification process is accompanied by the destruction of alkalinity (e.g., bicarbonate, HCO3-, is neutralized to carbonic acid, H2CO3). Alkalinity is recovered as part of the denitrification process with the generation of hydroxide. The chemical equations involved in the biological conversion of nitrogen are as follows: 1. Formation of ammonia fro
