Sustainable greenhouses have gained relevance in recent years due to their potential reduce the carbon footprint of agricultural sector by being integrated with renewable systems, contributing decarbonization energy. Although solar technologies tend be more accessible cover system’s energy demands, are subject installation area restrictions, limiting potential. This research evaluates advantage...

The purpose of the Guideline Manual is to provide recommendations for the application of combined gas reburning-sorbent injection (GR-SI) technologies to pre-NSPS boilers. The manual includes design recommendations, performance predictions, economic projections and comparisons with competing technologies. The report also includes an assessment of boiler impacts. Two full-scale demonstrations of...

The sintering behaviour of several green compacts made with olivine or olivine/alumina powder blends has been examined. To this goal, powders were attrition milled, uniaxially pressed into specimens and air sintered at temperatures ranging from 1100 to 1300 °C. The resulting samples were characterized by water absorption, shrinkage, phase composition and density. Compositions containing 5%, 10%...

this study was conducted to determine the prevalence of salmonellae contamination of chicken carcasses in slaughterhouses in central iran (yazd province). 435 samples were obtained from liver, breast— before and after chilling—and bacteriological and serological examinations were done. the results showed that the rate of contamination of liver, breast meat—before and after chiller—were 8.1, 18....

To generate electricity, Gas Turbine Power Plants are extensively used around the world but their efficiency is negatively affected on hot days by ambient air temperatures. and output power will decrease 2% 12.5% respectively at temperature 40°C due to lower density resulting increase in compressor specific work. 
 Ordinarily, cooling down intake of gas turbine facilitated employing a vari...

In hot and dry regions such as the Gulf Cooperation Council (GCC) countries, cooling demand is often responsible for more than 70% of electricity consumption, which places a massive strain on grid leads to significant emissions. Solar thermal driven Silica-Gel/Water adsorption chillers, used space cooling, could provide low carbon emission reduce reliance electricity. However, meticulous design...

Ecological experiments on fire ants cannot, or should not, use poison baits to eliminate the fire ants because such baits are not specific to fire ants, or even to ants. Hot water is an extremely effective and specific killing agent for fire ant colonies, but producing large amounts of hot water in the field, and making the production apparatus mobile have been problematical. The construction a...
