in this research the microorganism was initially isolated and selected after evaluation based on cod reduction of cheese whey and biomass production. the selected microorganism was identified as trichosporon sp. the cultivation conditions of the microorganism were optimized under batch: temperature 30˚c initial ph = 6 aeration speed = 2 ν.ν.m and agitation rate: 800 rpm. under these conditions,...

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...

drying properties of high moisture potato slices with initial moisture content of about 4.06 (db) under thin layer fixed, semi fluidized and fluidized bed conditions were studied. drying air temperatures of 40, 50, 60 and 70°c were applied in experiments using a laboratory fluidized bed convective dryer. in order to predict the drying behavior of potato slices, seven thin layer drying models we...

Background: Work-related musculoskeletal disorders (WMSDs) are from among the most prevalent occupational health problems leading to high costs and reduced productivity in nurses. Therefore, the present study aimed at investigating musculoskeletal disorders (MSDs) in nurses and their correlation with demographic factors and awareness of ergonomics at the selected hospitals of Shahid Beheshti Un...

in this study fungi isolated from the effluent of ethanol factories were identified. optimal conditions for single cell protein (scp) production and cod reduction of sugar beet stillage are specified for a species of hansenula in a continuous culture. under these conditions 5.7 g dm-3 biomass was produced and 31% of cod was reduced without addition of further nutrients to the beet molasses stil...

Recently, global warming problems with rapid population growth and socio-economic development have intensified the demand for water and increased tensions on water supplies. This research evolves the Multi-Objective Coronavirus Optimization Algorithm (MOCVOA) to obtain operational optimum rules of Voshmgir Dam reservoir under the climate change conditions. The climatic variables downscaled and ...
