Reasons for converting to sustainable farming have been studied in a number of instances. However, the underlying rationale that ...

Recent talks have outlined the disadvantages of land based (agro-fuels) as feedstock for biofuels. This final dissertation for the MBA in Energy and Sustainable Development looks at these disadvantages and proposes an alternative scenario, i.e. the potential of aquatic alternatives. Aquatic Biofuels: New Options for ...

Ten vibrocores were collected from the outer, middle and inner part of the tidal flats off Busum (German North Sea coast) to identify the gradual changes in sediment composition and sedimentary structures due to their location and input of hydrodynamic energy. The outer part of the investigation transect includes ...

Surface tension is one of the major issues encountered in the oil industry. This study investigated the laboratory effect of temperature and impurities on surface tension of crude oil samples and water. The aforementioned tests were carried out (in line with industrial standard) on the samples in order to ...

This study was conducted in South Africa. South Africa is the first country within the Southern African Development Community to have regulated plastic shopping bags waste through the imposition of both a standard on thickness and a levy. Given this scenario, the Plastic Bags Regulations present an illustrative case ...

The Agulhas Retroflection transfers heat, salt and vorticity from the Indian Ocean to the South Atlantic. The transfer is accomplished by discrete meso-scale features and by the advection of a water column of mixed Atlantic and Indian Ocean origins. The objectives of this thesis are to measure the strength of the ...

Groundwater represents an important supply source for municipal and irrigation uses in Far West Texas. The City of El Paso receives about 50 percent of its municipal water supply from surface water and 50 percent from local groundwater.

A field experiment was conducted at farmer’s field of Anandapur, Mangalpur VDC-3, Chitwan, Nepal during winter season from September 2006 to February 2007 to study the effects of nitrogen and plant population on maize. Fifteen treatment combinations consisting of five levels of nitrogen: 0, 50, 100, 150 and 200 kg ...

The efficiency of a probabilistic hydrological forecasting system with weather radar and the Probability distributed hydrological model (PDM) was evaluated at the Brue catchment; south-western England. The ability of the radar to measure gauged precipitation in 2007 (regarded as the ground truth) was evaluated using ...

In recent years, due to expanding populations and industries, regulatory authorities have imposed tighter discharge limits on nutrients from wastewater treatment facilities to avoid eutrophication in water streams. Common methods, such as metal salt precipitation, are being used to lower phosphorus concentrations ...
