چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...
bovine ephemeral fever (bef) is an acute epidemic disease in cattle and water buffalo, spanning tropical and subtropical zones of asia, australia, and africa. in recent years, bef has been distributed in many provinces of iran and caused economic losses. in this study the sequence encoding the g1 epitope of bovine ephemeral fever virus (befv) g glycoprotein was amplified by pcr, ligated into th...
three new rimantadine schiff bases (rsbs) were prepared, and then the interaction of rsbs with bovine serum albumin (bsa) was investigated using fluorescence, synchronous fluorescence, uv-vis absorption spectroscopy under physiological conditions. the results showed that the three rsbs effectively quenched the intrinsic fluorescence of bsa via static quenching. binding constant (ka), number of ...
the aim of the present study was to find the effects of pre and post vitrification taxol treatment on bovineimmature cumulus oocyte complexes (cocs). bovine ovaries were collected from the local slaughterhousein a container with 30-37°c physiologic saline and supplemented with antibiotics. the grade a aspiratedcocs were assigned to 6 experimental groups; the 1st group was control (n=100) in whi...
the objective of this study was to compare an indirect elisa, based on a purified 60 kda envelope glycoprotein (gp51su), with a pourquire indirect elisa for the detection of antibodies to the bovine leukemia virus. for conducting this research, 340 serum samples were collected from two different breeds of cows (sarabi and holestin) in different herds. commercial elisa revealed positive results ...
the measurement of antibody responses of animals exposed to bvdv either through a natural exposure or an immunization protocol is still a standard procedure. for bvdv, the test formats have been largely limited to elisa which is a valuable diagnostic test to measure the level of bvdv specific antibodies as well as antigen in blood samples. in the present study, 120 blood samples were collected ...
PURPOSE To define global transcriptional responses of Staphylococcus aureus and its codY mutant (CodY is a transcription regulator of virulence and metabolic genes in response to branched-chain amino acids) when growing in bovine aqueous (AH) and vitreous humor (VH) in vitro, and to investigate the impact of codY deletion on S. aureus virulence in a novel murine anterior chamber (AC) infection ...
For nearly 30 yrs, the mucus-depleted frog palate has been used to measure the ciliary transportability of respiratory and other mucus gels, but the data obtained from this amphibian digestive system may not be applicable to human airway mucociliary clearance. This study compared this model with the mucus-depleted bovine trachea, a mammalian respiratory system. Assessments were made of the repr...
