monoxide (CO)‚ oxides of nitrogen (NOx)‚ volatile organic compounds (VOCs) and particulates‚ which have an increasing impact on air quality. In addition‚ photochemical reactions resulting from the action of sunlight on nitrogen dioxide and volatile organic compound from vehicles leads to the formation of ozone‚ a secondary long range pollutant‚ which impacts in rural areas often far from the original emission site. Acid rain is another long range pollutant influenced by vehicle nitrogen oxide emissions.

there exists many problems of construction materials industry. Energy consumption of construction materials industry accounts for 7% of national total energy consumption and 10% of industrial energy consumption. Because of dust‚ sulfur dioxide and nitrogen oxide emissions‚ building materials industry is the key industry national emission regulation. Therefore‚ green development‚ recyclable development and low carbon development become the healthy development of building materials industry direction

“How humans impact the Carbon‚ phosphorus‚ and nitrogen cycles” Christine Richardson Environmental Science May 1‚ 2013 The carbon cycle is based on carbon dioxide which is a very important element because it is a part of all life. All living things are made of elements such as oxygen‚ carbon‚ hydrogen‚ nitrogen‚ calcium‚ and phosphorus. There are such compounds that are necessary for life such as sugars‚ fats‚ proteins etc. that joins with carbon to form these essential

ABSTRACT An experiment was carried out at the Horticulture Farm‚ Bangladesh Agricultural University‚ Mymensingh during 1998-99 growing season to study the effect of nitrogen and plant spacing on the growth and yield of potato (var. Diamant). Different nitrogen levels viz. 0‚ 127.0‚ 190.5 and 254.0 kg N/ha significantly influenced plant height‚ foliage coverage‚ number of main stem per hill‚ days required for 80% maturity of the crop‚ fresh weight of haulm (g/hill)‚ number of tubers per hill‚

nutritional security and reduction of hunger. Potato plant like other tuber crops requires sufficient supply of several essential elements for proper growth and function. It is a gross feeder and exploiting greater volume of soil nutrients including nitrogen‚ phosphorous‚ potassium and water. Potato production has become very important in Rwanda in terms of land cropped and income generated to the potato farmers. Despite this importance‚ the production of potato is still low comparatively to the potential

important because it is a measurement of renal function .A more complete estimation of renal function can be made when interpreting the blood (plasma) concentration of creatinine along with that of urea. BUN-to-creatinine ratio (the ratio of blood urea nitrogen to creatinine) can indicate other problems besides those intrinsic to the kidney; for example‚ a urea level raised out of proportion to the creatinine may indicate a pre-renal problem such as volume depletion. The typical human reference ranges
