Background and Objectives: Assessing human bioclimatic is foundation for many programs and plans, especially in the field of healthcare. In this study, human thermal comfort and its relationship with the incidence of diseases were investigated in Kurdistan province. Materials and Method: The daily data of temperature, wind speed, relative humidity, and cloudiness between the years 1995-2014...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...
to evaluate the effect of biofertilizers on yield and yield components of a soybean cultivar (m9) under water stress condition, a study was carried out in a split plot randomized complete block design with three replications at research station of bu ali sina university in 2012. the main plots included three levels of irrigation after 50, 100 and 150 mm evaporation from a pan and subplots inclu...
Abstract Background: The correlation between QT dispersion (QTd) and myocardial ischemia is controversial. The main purpose of current study was to investigate the relationship between QTd and the severity and extent of myocardial ischemia. Methods: In this cross sectional study, 100 patients with suspected coronary artery diseases (CAD) were studied. Based on the results of the myocardial ...
The salinity of the soil and irrigation water is one great challenges agriculture. Salinity can have harmful effects on physiological processes plant growth, including Tropaeolum majus L. (Tropaeolaceae). application phytohormones be a strategy to mitigate these effects. aim this study was evaluate jasmonic acid, salicylic cytokinin polyamine as attenuators salt stress in T. majus. Three levels...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
in order to investigate of quality and quantity yield and growing degree day (gdd) of plantago ovata and p. psyllium related to water stress and density, two experiments were conducted at the agriculture research field, tehran university, karaj, in april 2005 and 2006. the experiments were designed in factorial experiments based in randomized completely block (rcb) with three replication in whi...
