Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...

Effects of different levels of cadmium (0.1, 1, 2, 4, 8, 16, 32, 64, 128, 256 mg/l of culture medium) were evaluated using gas production technique. In the glass vials used to measure gas production 30 mg of buffered rumen fluid (2:1 ratio of rumen fluid: buffer) poured in glass and cultured at 38.6 temperature. Volume and pressure of produced gas were measured with syringes and digital pressur...

abstract             this study was conducted to investigate the effects of different levels of yeast and molasses on chemical composition and nutritional value of artiplex lentiformis silage. the levels of yeast include: zero (control), 2.5 and 5 g/kg dry matter and levels of molasses include: zero (control), 10 and 15 percent that were added to atriplex and then ensiled. the experiment arrang...

This study aims to evaluate the status of Iranian gas industry and to formulate appropriate policies in order to attain the objectives of Iran’s Vision 2025. A dynamic model including exploration, production, consumption and demand sub-systems is designed based on the system dynamics approach and is simulated for the period 2010-2025. In this model, factors affecting natural gas exploration, de...
