The objectives of this study were to evaluate the effects of Burdizzo castration and abrupt weaning on the behaviour, blood traits and performance of beef calves when weaning was conducted concurrently or consecutively to castration. In total, 64 male beef calves aged between 6 and 7 months were assigned to a 2×2 factorial design with the following treatment groups (n=16 animals per treatment):...
nolol is essentially complete, with no metabolism of this drug occurring in the gut. After the oral administration of propranolol, the liver is the principal site of extensive presystemic and systemic metabolism, and less than 1% of the intact drug is found in urine. However, Bianchetti et al. showed that the area under the concentration–time curve for orally administered propranolol in renal f...
سازه‌های مهندسی معمولاً با استفاده از اتصال مواد فلزی به‌هم برپا می‌شوند. با این‌وجود، با افزایش کاربرد مواد پایه پلیمری، طراحی اتصالاتی که ترکیبی از کامپوزیت‌ها و فلزات می‌باشند، روزبه‌روز بیشتر مورد توجه قرار می‌گیرد تا بتوان از مزایا و ویژگی‌های دو مادة مختلف به‌طور همزمان استفاده کرد. لذا ضروری است با بررسی و طراحی درست اتصالات نامتوازن، عملکرد بهینه‌ای برای هر دو قسمت چسبنده به‌دست آورد. در...
این پژوهش قصد دارد تا استحکام و سفتی استاتیکی و عمر خستگی اتصال چسبی تک لبه ای را با استفاده از مدل ناحیه چسبناک، تحت شرایط هندسی مختلف مورد ارزیابی قرار دهد. برای این منظور در شبیه سازی لایه چسب از مدل ناحیه چسبناک دو خطی بهره برده شده به نحوی که طی بارگذاری مود ترکیبی رفتار شکست چسب در مود iii با رفتار شکست آن در مود ii یکسان در نظر گرفته شده است. در ادامه، برای مدل سازی آسیب خستگی از زیر روا...
39 Introduction Within Nebraska, the Tallgrass Prairie Ecoregion occupies the approximate eastern one–third of the state and was historically characterized by extensive grassland habitats with scattered areas of upland deciduous forests and savannas, and lowland prairie or deciduous forests along riparian drainages (Kaul et al. 2011, Schneider et al. 2011). A nearly complete conversion of tallg...

The paper presents the methodology and the outcome of the compilation and the processing of the Bulgarian X-language Parallel Corpus (Bul-X-Cor) which was integrated as part of the Bulgarian National Corpus (BulNC). We focus on building representative parallel corpora which include a diversity of domains and genres, reflect the relations between Bulgarian and other languages and are consistent ...
To study the role of circulating natriuretic factors in the postobstructive diuresis that occurs after relief of bilateral, but not unilateral ureteral ligation, cross-circulation was carried out between normal recipient rats and donor rats have either 24-h bilateral (BUL) or unilateral (UUL) ureteral ligation. With BUL donors, there was a rapid marked increase in sodium and water excretion in ...
A search for extra-solar planets was carried out in three gravitational microlensing events of high magnification, MACHO 98–BLG–35, MACHO 99–LMC–2, and OGLE 00–BUL–12. Photometry was derived from observational images by the MOA and OGLE groups using an image subtraction technique. For MACHO 98–BLG–35, additional photometry derived from the MPS and PLANET groups was included. Planetary modeling ...
