Different water treatment processes (physical and chemical) exist to obtain safe water for human or food industry supply. The advanced oxidation technologies are rising as a new alternative to eliminate undesirable chemicals and waterborne diseases. In this work, we analyze the power of the photo-assisted Fenton process using Fe(II)/H2O2 and UV radiation (365 nm) to inactivate Bacillus subtilis...

nowadays energy is one of the most essential needs of human being and it can be considered as the basic prerequisite of social and economic development.  hence, many of the correlations and legislations of a country are affected by it. since iran has huge source of gas and oil, it has turned to a fossil fuel oriented county. but as oil and gas sources are non-renewable ones and cannot be replac...

An anatase TiO₂ film sensor was prepared by a facile in-situ method on the interdigitated Au electrode deposited on the alumina substrate. The structure, morphology and the optical properties of the in-situ TiO₂ film sensor were characterized by X-ray diffraction, Scanning Electron Microscopy, and UV-vis diffuse reflectance spectra. The photo-assisted gas sensitivities of the prepared film towa...

The exploitation of thermal water as a heat source in houses and apartments (during winter) is a widely used alternative to natural gas. However, this type of water may contain organic contaminants, which must be removed before releasing the used water into rivers and lakes. Because of the presence of a wide range of pollutants (including phenolic compounds and humates), efficient, cheap remova...

Environmental considerations will probably change automobile fuels from gasoline and gas-oil to hydrogen (as fuel cell) in the future. Problems of fossil fuels include producing gaseous pollutants, such as NOx, CO, and even SO2 (from incomplete-hydrotreated fuels), which need catalytic converters and greenhouse gas emission (such as CO2, CH4, N2O) from the exhaust with a drastic effect on globa...

eries, water in egg-hatching or fry-rearing tanks may have a condition called “gas supersaturation” that is harmful to fish. Gas supersaturation means that the water contains more gas at a certain air (barometric) pressure and water temperature than would normally occur if the water was allowed to come to equilibrium with the atmosphere. Fish living in such waters may develop a stressful or let...

pulmonary hypertension syndrome (ascites) is a metabolic disorder in fast-growing broilers. inconsistency of oxygen requirement and the cardiovascular ability make the birds susceptible to ascites. incidence of ascites was accompanied by right ventricular hypertrophy, fluid accumulation in the abdominal cavity and finally mortality. the objective of the current study was to review the genetic b...

Post-Hartree-Fock ab initio quantum chemical calculations were performed for 5-fluorouracil in the gas phase and in a three-water cluster. Full geometry optimizations of the 5-fluorouracil-water complexes were carried out at the MP2/6-31+G(d,p) level of theory. MP4/6-31+G(d,p)//MP2/6-31+G(d,p) and MP4/6-31++G(d,p)//MP2/6-31+G(d,p) single-point calculations were performed to obtain more accurate...
