four ruminally-cannulated holstein cows were used in a 4 × 4 latin square changeover design within periods of 21 days to evaluate effects of feeding frequency of different sources of rumen degradable nitrogen on total tract digestibility of nutrients, feeding behaviors, rumen and blood metabolites of holstein cows. treatments were: 1) control diet which was as total mixed ration (tmr) offered o...

In this study, the effect of short-terms starvation (0, 2, 4 and 8 days) on plasma cortisol, glucose, triglyceride and cholesterol levels and also hepatosomatic index in Siberian sturgeon, Acipenser baerii, was investigated. After acclimation to experimental conditions for 10 days using formulated diet, 180 juvenile Siberian sturgeons (mean weight ? S.E.=19.3?0.4, n=15) were randomly distribute...

the paper is based on a study conducted in three different industries on 84.4 on their employees to determine the effect of over all noise intensity, length of employment and rest periods among them. it was found that the mentioned factors have direct effect on the induced hearing loss among the exposed workers. high noise level and long period of employment adversely affect the hearing ability...

drought is a major problematic phenomenon mostly for semi-arid areas of iran. during drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. therefore, the assessment of drought effects on plant covers is the most important issue. this research was conducted in 2015 using the extracted vegetation indices from moderate resolution ima...

The inhaled corticosteroid fluticasone furoate (FF) and the long-acting β₂ agonist vilanterol (VI) are in development as a combined once-daily therapy for asthma and chronic obstructive pulmonary disease. Our study objectives were to compare the efficacy and safety of once-daily FF/VI with FF alone and twice-daily fluticasone propionate (FP) in patients aged ≥12 years with moderate-to-severe pe...

Human mobility is differentiated by time scales. While the mechanism for long time scales has been studied, the underlying mechanism on the daily scale is still unrevealed. Here, we uncover the mechanism responsible for the daily mobility patterns by analysing the temporal and spatial trajectories of thousands of persons as individual networks. Using the concept of motifs from network theory, w...
