vehicles‚ we suggest installing a 3-way catalytic converter‚ which can oxidize carbon monoxide to carbon dioxide 2CO + O2 ---> 2CO2‚ unburnt hydrocarbons to carbon dioxide and water CxH2x+2 + (3x+1)/2 O2 ---> xCO2 + (x+1) H2O and reduce nitrogen oxides to nitrogen and oxygen 2NOx ---﹥N2 ＋ xO2. Nevertheless‚ the catalytic converter cannot be used on leaded petrol vehicles because Lead will poison the catalyst such as Platinum inside the converter. Indeed‚ there are more possible solutions to solve

In order to release the nitrogen into soil‚ this polymer coating will be very effective. This product will send nitrogen for defined time and they use this product in manner so that‚ crops will intake particular amount of nitrogen at each stage of its growth. In more detail‚ this product is mainly designed to reduce the release of nutrient for the one month period after the single application in order to use the nitrogen supply effectively. The application of this product

The productivity of these soils is generally low in most of the existing farming system. These soil problems have necessitated the intensification of research in this geographical zone. These include research into biological nitrogen fixing systems as an alternative to chemically produced fertilizer. Certain leguminous plants are presently being considered for integration into southern Guinea savanna by a team of scientist. A recent investigation by Adesida (2009) has established

will work including the mass and energy balance across the plant. What is Ammonia Ammonia (NH3) is a stable compound and is used as a starting material for the manufacture of many important nitrogen compounds and can also be directly used as fertilisers. It is produced by reacting hydrogen and nitrogen. It is a colourless gas with a sharp odour. The boiling point is -33.35oC and its freezing point is -77.7oC.1 Care must be taken when handling ammonia as can cause deep burns in the skin; irritation

once was home to early residents of St. Paul-many of them immigrants‚ who settled in shantytowns along the river. By converting from coal to natural gas the plant has significantly reduced all air emissions from the plant-particulates by about 92%‚ nitrogen oxide by almost 97%‚ sulfur dioxide by 99% and 100% of mercury emissions. High Bridge also has been a major sponsor and participant in the Mississippi riverfront greening project in downtown St. Paul that involved the planting of hundreds of trees

The article I chose relates to the nitrogen cycle covered in the book and in class. My article is titled Nitrogen Fertilization Changes Abundance and Community Composition of Ammonia-Oxidizing Bacteria. I liked the research and believe that it is very thorough I also understand the importance of bacteria on soil health. Shen‚ W.‚ Lin‚ X.‚ Gao‚ N.‚ Shi‚ W.‚ Min‚ J.‚ & He‚ X. (2011).
