burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
Soil organic matter and clay minerals adsorb and immobilize extracellular enzymes of microorganisms and increase soil enzymes stability. This study aims to clarify the relative importance of soil organic matter and clay minerals on the cellulolytic activities of soils. Fluca prepared cellulase was immobilized on some agricultural residues and clay minerals, avicel and a sample of soil. Immobili...

With a few exceptions, today’s mobile robots, however complex, are not truly autonomous. At some time, they all require humans to supply them with energy and/or information; most also require other forms of assistance. In complete contrast, even the simplest animals are totally self-sufficient. We describe a current project1 which aims to construct autonomous robots with animal-like self-suffic...
The toxicity and corrosion potential of hydrogen sulfide in raw biogas underlines the need for biogas purification. Several techniques available for removal of hydrogen sulfide from biogas are out of the reach for common end users due to lack of knowledge, higher running costs, and insufficient operational skills. The present experimental study aims to propagate hydrogen sulfide removal techniq...
The Sustainable Value methodology was used to compare and rank eight combinations of waste biomass types conversion technologies on a common assessment basis produce energy, energy vectors advanced biofuels. studied included agricultural agro-industrial residues, slurries effluents, pulp paper mill sludge, piggery effluents organic fractions municipal solid waste, biodiesel by (trans)esterifica...
With Increasing Energy Demand in the World and to keep Environment Friendly, biogas technology has attained a notable position for the future scope. This paper tells about a comprehension review on anaerobic digestion of cow dung and food waste with Water hyacinths to enhance biogas productions. Water hyacinths are treated as waste in rivers, ponds, but they have high potential in biogas produc...
The purpose of this work was to study the effect of initial pH and yeast Saccharomyces Cerevisiae on biogas production from tofu wastewater (TW). The initial pH was varied in ranging of 5 – 9 in substrate without yeast (T5-T9) and with yeast (TY5-TY9). The results showed that optimum initial pH was 8. The maximum biogas was resulted in T8 (275 mL) and TY8 (421 mL). Yeast addition increased tota...
purpose: the purpose of this paper is to evaluate to what extent the construction of common and individual biogas plants can answer the fuel needs of rural people or families. methodology: the present study with descriptive - analytical method, examines the fuel needs of the rural people and its supply by biogas from livestock waste. findings: the primary outcome of the proportion of rural popu...
