In this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. The influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final pH and energy consumption rate was determined. Dye removal was increased with increases in solution pH, current density and c...

Regenerative Fuel Cell (RFC) systems are used for the enhancement of sustainable energy aspect in conventional fuel cells. In this study, a photovoltaic-electrolyzer-fuel cell integrated cycle has been presented. The proposed system has been designed as a novel approach for alleviating the restrictions  on energy streams in the RFC systems. Modeling of the system has been performed from the mas...

Radiation damage depends on energy absorption, and is approximately proportional to the absorbed energy density in the tissue. In external radiation consideration with a certain energy flux, the amount of absorbed dose in each point of the tissue depends on the type of radiation, the radiation energy, the depth of the place of receipt, and the main components of the absorber environment. The ab...

The remarkable development of sciences and technologies in the world of]o today has apparently brought mankind comfort and well-being, but it has also created new problems for humans including environmental pollution, widespread changes in world weather conditions, etc. Fossil fuels cause numerous environmental pollutions. In other words, on the one hand poisonous gases enter the environment fo...

energy management is one of the main ways of the efficient use of energy resources. the prediction of crop yields based on energy inputs can help farmers and policymakers to estimate the level of production. required data for study were randomly collected from 70 broiler farms in north west of iran. the input energies were included human labour, machinery, fuel, feed and electricity and the out...

Cylotrimethylenetrinitramine (RDX), with the chemical formula C3H6N6O6,is an energetic organic molecule used widely in military and industrial commodities ofexplosives. By stimulating RDX through exerting temperature or mechanical conditionssuch as impact or friction, decomposition reaction occurs at a very high rate. Moleculardynamics techniques and LAMMPS code with Rea...
