the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
In order to investigate of effect of salinity (NaCl) on soluble sugars and mineral ions concentrations in salt tolerant (IR651) and sensitive (IR29) rice (Oryza sativa L.) genotypes, a factorial based on a completely randomized design was carried out in greenhouse of physiology division of Agricultural Biotechnology Research Institute of Iran (ABRII) in 2006. Seedlings were grown in Youshida nu...
a factorial experiment based randomized complete block was conducted in order to investigation of two rice (oryza sativa l.) genotypes responses for na+, k+, ca2+, mg2+, clˉ, mn2+, p and total soluble sugars accumulation and compartmentation in leaves 3, 4, 5 and 6 to salt stress. in estimation of the simple correlation between traits, dry weight was negatively correlated with na+ and clˉ. the ...
fourteen primiparous holstein cows (180.0 ± 4.3 days in milk) with a mean (±sd) daily milk yield of 35.0 ± 1.3 kg and a body condition score of 3.2 ± 0.2 were allotted into two groups (n = 7), and were fed a ration consisting of (dry matter basis) 35% corn silage, 25% alfalfa hay and 40% concentrates. salt was provided free choice. the experiment was performed during the period of heat stress, ...
This study aimed to investigate the toxic effects of atrazine herbicide on the fry of Caspian Kutum (Rutilus frisii kutum, Kamensky, 1901). First the 96-h LC50 of the fry were exposed to atrazine at the concentration of 24.95 ppm was determined. Then the toxicity of this herbicide on Caspian kutum fry exposed to the concentration of 12.47ppm (1/2 LC50), for four days was measured and compared w...
