Biodiesel is one of the promising renewable, alternative and environmentally friendly biofuels that can be used in diesel engine with little or no modification in the engine. In the present study an experimental investigation has been carried out on the combustion and performance characteristics of a CI engine running with biodiesel under steady state operating conditions. The experimental work...

The main objective of this work is to select the optimum city from five touristic Egyptian cities (Luxor, Giza, Alexandria, Qena and Aswan) to establish an environmentally-friendly tourist village. The selection of the city, according to the economic cost (cost of energy (COE), net present cost (NPC)) and the amount of greenhouse gases (GHG) emitted, is carried out with respect to four cases, b...

BACKGROUND Diesel exhaust exposure may cause acute irritant-induced asthma and potentiate allergen-induced asthma. There are no previous reports of occupational asthma due to diesel exhaust. AIMS To describe occupational asthma with latency in workers exposed to diesel exhaust in bus garages. METHODS The Shield database of occupational asthma notifications in the West Midlands, UK, was sear...

OBJECTIVE To biodegrade the diesel pollution in aqueous solution inoculated with Mycobacterium and filamentous fungi. METHODS Bacteria sampled from petroleum hydrocarbons contaminated sites in Karamay Oilfield were isolated and identified as Mycobacterium hyalinum (MH) and cladosporium. Spectrophotometry and gas chromatography (GC) were used to analyze of the residual concentrations of diesel...

ethanol extracts of donkey thistle (Onopordum acanthium L.) was conducted.

A (without extracts) used as control. addition 50% extract Onopordum L. increased total volatile composition variants 1000:20 1000:50, comparison control samp...

A global concern that has arisen in the present time due to the constant depletion of the fossil fuels reservoirs and also due to the greenhouse gases emitted by use these fuels has led many researchers to find alternate sources of energy, out of which biodiesels have found a suitable place. Thus, in this effort of finding the compatibility of bio-fuels in present diesel engines, many experimen...
