Drying via solar energy is an environmentally friendly and inexpensive process. For controlled bulk level drying, a greenhouse dryer the most suitable dryer. The efficiency of can be increased by using thermal storage. agricultural products dried in greenhouses are reported to higher quality than those sun because they shielded from dust, rain, insects, birds, animals. heat storage-based was fo...

Effects of rice-cultured Paecilomyces lilacinus on Rotylenchulus reniformis were studied in both greenhouse and field microplot tests with 'Rutgers' tomato. Numbers of R. reniformis were reduced (P </= 0.05) by P. lilacinus, with suppression in the initial greenhouse test ranging from 46 to 48% for two rice + P. lilacinus treatments; the rice-only treatment caused a nonsignificant reduction of ...

Computer simulations of the evolution of the Earth's atmospheric composition and surface temperature have been carried out. The program took into account changes in the solar luminosity, variations in the Earth's albedo, the greenhouse effect, variation in the biomass, and a variety of geochemical processes. Results indicate that prior to two billion years ago the Earth had a partially reduced ...

sustainable development of the production in every region requires consideration of energy flow in the production system, moreover, investigating the production system inputs from environmental management point of view is of high importance. in this study energy use and greenhouse gas emissions is investigated. data were collected through interviews with 75 tea farmers and comparing the results...

As a potential offsetting agent to the greenhouse effect, aerosols are receiving increasing attention in the atmospheric science community. Notwithstanding, our knowledge of the impact of aerosols on radiation and climate is rather poor and falls well behind that of the greenhouse effect (IPCC 1995). Direct radiative forcing (DRF) of aerosols is an important climatic parameter measuring the inf...

climate change is occurring as a result of warming of the earth’s atmosphere due to human activity generating excess amounts of greenhouse gases. because of its potential impact on the hydrologic cycle and severe weather events, climate change is expected to have an enormous effect on human health, including on the burden and distribution of many infectious diseases. the infectious diseases tha...

Model-based control techniques are commonly applied to control the greenhouse climate. As well-known, these techniques require accurate models for adequate results. Several first-principle models have been developed for the greenhouse climate control problem considering all the physical and physiological processes. However, these models are too complex to be used for control purposes. On the ot...

The main purpose for developing biofuel is to reduce GHG (greenhouse gas) emissions, but the comprehensive environmental impact of such fuels is not clear. Life cycle analysis (LCA), as a complete comprehensive analysis method, has been widely used in bioenergy assessment studies. Great efforts have been directed toward establishing an efficient method for comprehensively estimating the greenho...
