abstract the main purpose of this study was to determine farmers’ satisfaction towards pressurized irrigation systems in kermanshah province. this study used a mixed method design with descriptive correlation emphasis. a researcher made questionnaire was used to collect data. a random sample of 274 farmers who have been equipped with pressurized irrigation systems during the last three years pa...

pressurized irrigation technologies of course have the potential to raise the productivity of land and water; but, these technologies could not popularize among the smallholders who own millions of farms worldwide. in developing pressurized irrigation technologies, particularly for field crops irrigation, researchers and manufacturers have developed more specialized and expensive technologies w...

Iodine determination in food samples was performed by inductively coupled plasma mass spectrometry (ICP-MS) after digestion by microwave-induced combustion (MIC). Sample masses up to 500 mg of bovine liver, corn starch, milk powder, or wheat flour were completely combusted using the MIC system. Ammonium nitrate (6 mol l(-1) solution, 50 μl) was used as an aid for ignition and vessels were charg...

Hermetic pressurized buildings have been developed to reduce the effects of high altitude. The behavior and effect fire in this new type building not studied before. Unlike common buildings, inside pressure is maintained at around standard atmospheric pressure, which significantly higher than outside environment altitude regions. In addition, early stage a fire, oxygen required maintain combust...

Two and three-dimensional simulations of experiments on atmosphere mixing and stratification in a nuclear power plant containment were performed with the code CFX4.4, with the inclusion of simple models for steam condensation. The purpose was to assess the applicability of the approach to simulate the behaviour of light gases in containments at accident conditions. The comparisons of experiment...

in this study, application ofweap model (soil moisture method) have been investigated for simulating hydrological behavior in ahar-chai basin. according to the development of pressurized irrigation systems in this basin, since 2005, two models were carried out for two periods, pre-pressurized period (1998-2006) and pressurized period (2006-2013). irrigation method in first model was surface irr...
