This study was aimed to analyze the metabolic activity and membrane integrity of boar spermatozoa following storage in long-term semen extenders. Boar semen was diluted with Androhep EnduraGuard (AeG), DILU-Cell (DC), SafeCell Plus (SCP) and Vitasem LD (VLD) extenders and stored for 10 days at 17C. Parameters of the analyzed sperm metabolic activity included total motility (TMOT), progressive m...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the aim of this research was the collection and freezing of honey bee sperm, apis mellifera, as a trail and evaluating different semen extenders to improve sperm quality after freeze-thawing process as a first trail in iran. semen was collected using artificial insemination device. in this experiment three different extenders including; egg yolk (tey), buffer and 0.5% soybean lecithin (tsl0.5) ...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
Bovine serum albumin (BSA) is commonly used in adipocyte experiments as a binding protein for fat-soluble substances. Therefore, it is of interest to investigate whether BSA per se is influencing the functioning of human adipocytes in vitro. In the present study, we investigated the potential of BSA to affect the proliferation and differentiation capacity of human preadipocytes. BSA was found t...
background: active immunization with gonadotropin releasing hormone conjugate (gnrh-bsa) manipulates the fertility axis and thus alters the reproductive cyclicity serum estradiol and progesterone levels. while the application of kamdhenu ark increases the efficacy of gnrh-bsa. objective: this experimental investigation is aimed to evaluate the modulatory effects on estrous cycle serum estradiol...
this study investigates the effect of teacher’s repetition as an input enhancement technique in explicit teaching of vocabulary items on efl learners’ later retrieval. to this end, 66 persian speaking english learners, aged 18 - 29, homogenized through a standard proficiency test (opt), were chosen and put into two experimental and control groups, each 33 learners. general service list (gsl), a...
Determination of the BSA-palmitate high-affinity binding constant ( K a) traditionally relied on the heptane-water partitioning technique. We used this technique to calculate K a for the BSA-[3H]palmitate complex, to determine if K a was independent of protein concentration, and to determine if the unbound [3H]palmitate concentration is constant at different BSA concentrations using constant BS...
abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
