Nitrogen removal from wastewater using anaerobic ammonium oxidation Term Paper

Nitrogen removal from wastewater using anaerobic ammonium oxidation (Anammox) process - Term Paper Example Generally, this bacterial can be found almost everywhere. Findings have shown that the contribution of this bacterium on the removal of nitrogen in the environment can be immense. The process, said to be chemolithrophic, is a very new loop in the biogeochemical nitrogen cycle hitherto unknown to engineering (Dong & Sun, 2007). While there is very little, that is known about the ecology, genetics, or even the physiology of the bacteria, this research project will be very important in shedding some light on the community structure of the Anaerobic Ammonium Oxidation bacterial and all their involvement in environmental parameters that include nitrate, ammonium, and the salinity levels. This project discusses the effects of pH and salinity on the anammox process with results showing that the salinity is among the few factors that are really affecting the effectiveness of the whole process. My thanks go to Mr. XXXX through whose guidance I have learned molecular techniques used for the investigation of bacteria. It is due to his patient and undying support that pushed this study through. A good and encouraging attitude and his excitement about this work encouraged me to explore deeper into learning as much as possible in the process. I wish to also thank Ms. YYYY who also made this research a success through teaching me about the most fundamental and traditional microbiology techniques. Mr. QQQQ introduced the isotope ratio mass spectrometer to me. He was also very encouraging and it was through his words of wisdom that the concept behind stable isotope geochemistry became one that I can handle well, and with ease. This research owes its completion to WWWW who collected the sediment samples from XXX Estuary. All the other members of the microbiology laboratory were very helpful throughout my visits to the lab. It was their long, well-informed discussions that made the research a success, and I will forever cherish such

Return to haifa - Essay Example The, fleeing home of Said and Safeyya in Haifa during the 1948 Nakba can be equalled to the detaining of Nelson Mandela in 1962.   However, 20 years later, Said and Safeyya returned home only to find out that a Jewish family had actually adopted their son who entered Haifa (Suganda web). Likewise, for Nelson Mandela, he found out that many things had changed in his mother country South Africa when he was released from prison. Indeed, Mandela had to take time to adapt to his own country, which he had missed after many years in detention. Whereas Said and Safeyya find their home occupied by Miriam, Mandela found that the whites had indeed occupied the good parts of his country. The theme of regaining political identity after many years of detention for many political leaders shares the same story line with â€Å"Return to Haifa.† Although Mandela has been provided as an example, many political detainees all over the world experienced the same

Common Decency Assignment Example | Topics and Well Written Essays - 500 words

Common Decency - Assignment Example Unfortunately, the general manager of the hotel was arrogant and disrespectful to the hotel guests. Potential conflict may be avoided if the general manager did not express his emotions with regards to how frustrated he has become with regards to persons with disabilities. Escalation of conflict from potential to actual may be prevented by considering how the client must feel that he could not attend the wedding because his wheelchair could not pass through the function room. A pleasing tone in communicating to the guests may also prevent the escalation of conflict. 3. One conflict involved the non-availability of a room for one hotel guest, despite her presentation of a confirmation number for a reservation that was made two weeks earlier.

But today, there is no more doubt on this topic as the glaciers in the Arctic region of the world (located in the northernmost part of the Earth) are melting away fast due to the greenhouse gases caused by the burning of fossil fuels. Oil and coal are used to produce energy and electricity but they also produce by-products which are mainly carbon dioxide and methane that trap the sun heat energy. It is su pposed to be reflected back to outer space in a process called as Albedo effect. A warmer Earth has changed the ocean's surface temperatures and also its salinity with serious effects on marine life (Ehrlich 1) and caused rising sea levels. This brief paper examines all its effects on the populations of low-lying areas of the world and what can be done about it. Discussion Even the skeptics are now convinced that global warming really exists as manifested by weather that has gone haywire, as mentioned in an article by Mr. Hertsgaard like a â€Å"fiercer heat wave, harsher droughts, heavier rains and rising sea levels† (1). The top three polluters of the world are China, America and India, in this order of magnitude. â€Å"The world pumped about 564 million more tons (512 million metric tons) of carbon into the air in 2010 than it did in 2009. That's an increase of 6 percent. That amount of extra pollution eclipses the individual emissions of all but three countries - China, the United States and India, world's top producers of greenhouse gases. It is a "monster" increase that is likely unheard of, said Gregg Marland, a professor of geology who has helped calculate Department of Energy figures in the past. This extra pollution in China and the U.S. account for more than half the increase in emissions last year.† (Borenstein 1). What is even more alarming is the observation that even if all emissions are stopped or discontinued today, global temperatures will still keep rising for 25 years. There are basically two ways or approaches by which people can deal with the global warming phenomenon: first is mitigation and the second is adaptation. Mitigation pertains to a front-end approach of reducing gas emissions to slow down the warming trend and it includes using renewable and clean energy sources, such as wind power or solar power. The other end of the equation is adaptation which are actions intended to safeguard a community or country from the il l effects of global warming, such as rising sea levels that can inundate low areas. Mitigation – everybody can contribute to reducing greenhouse gases by living simple lifestyles. The idea is to reduce a person's carbon footprint by using less fuel in daily living. It entails, for example, using the car less and walking more often, or using a bicycle for moving around. There are many ways by which one can accomplish this, such as reducing the use of manufactured products or consumer items that use a lot of energy, reducing use of electricity, or by patronizing more

Dual and Cooperative Federalism Essay Example | Topics and Well Written Essays - 500 words

Dual and Cooperative Federalism - Essay Example The founders of federalism hoped to create a government system that is similar to a unitary system. However, the states were included in the system since they already had established government systems that were functional. Thus, the founders of the federalism granted the national government powers and reserve the remaining powers to the local or state governments. Moreover, these expressed powers given to the national government provide an avenue for expansion of the implied powers. Federalism further involves complex relationships among a number of states. For instance, in the United States of America, the constitution of United States of America requires the states to honor all the public acts and the decisions being made by the judiciary of other states. Moreover, federalism involves a number of limitations on the state authority, especially involving the relationships between the state governments. The local governments are not recognized in the federal constitution thus they are used by the states to perform or rather conduct normal activities of the government. Thus, federalism still remains the best governance system in United States of America. This is one of the US achievements as it transferred or rather created an effective constitution structure of the political institution. Hence, federalism and the entire separation of power in the national and state governments relieve other law enacting bodies off the burden of law implementation.
