so far, different methods have been applied to clean up soils contaminated with oil. bioremediation is one of the clean up technologies which uses microorganisms or microbial processes to degrade oil contaminations in soils. this study evaluates the applicability of cow manure as bioremediation alternative for soils spiked with petroleum hydrocarbons. target contaminant of this research was die...

the optimum dosage for field application bactimos (w.p.) was determined as 0.04g/m , when efficacy of four concentration of 0.01 , 0.02 , 0.04 and 0.08 gim2 were compared in 1 x i m2 artificial breeding sites. this dosage caused 69.8%, 55.6% and 43.6% anopheline and 83%, 47.8% and 29.7% culicine larval mortality, in 24.48% and 72 hrs post treatment, respectively. abate and fuel oil were signifi...

global air pollution is a serious threat caused by excessive use of fossil fuels for transportation. despite the fact that diesel fuel is a big environmental pollutant as it contains different hydrocarbons, sulphur and crude oil residues, it is yet regarded as a highly critical fuel due to its wide applications. nowadays, biodiesel as a renewable additive is blended with diesel fuel to achieve ...

Microbial fuel cells (MFCs) are emerging as promising technology for the treatment of wastewaters. The potential energy conversion efficiencies are examined. The rates of energy recovery (W/m3 reactor) are reviewed and evaluated. Some recent data relating to potato-processing wastewaters and a hospital wastewater effluent are reported. Finally, a set of process configurations in which MFCs coul...

The objective of this paper is to investigate the effect of fuel injection pressure on power performance and fuel consumption of diesel engine. In a diesel engine, fuel injection pressure is an important aspect of the engines’ power performance in order to obtain combustion treatment. The experiments in this paper are performed on a four-cylinder two-stroke direct injection diesel engine. The d...

The main aspects of fuel cell research is to reduce the cost and simplifying implementation conditions In recent years, people are moving towards microbiology ...

Landscape-scale fuel treatments for forest fire hazard reduction potentially produce large quantities of material suitable for biomass energy production. The analytic framework FIA BioSum addresses this situation by developing detailed data on forest conditions and production under alternative fuel treatment prescriptions, and computes haul costs to alternative sites at which forest biomass-bas...

Thermochemcial characteristics of powder fabricated using oxidation treatment of spent PWR fuel and SIMFUEL were evaluated for recycling of spent fuel such as DUPIC process. Especially, the influence of spent fuel burn-ups on the powder fabrication characteristics was experimentally evaluated, ranging from 27,300 to 65,000 MWd/tU. Densities of powder manufactured from an oxidation, OREOX and th...
