در این تحقیق نیاز اسید آمینه لیزین در بلدرچینهای ژاپنی نر و ماده، بر اساس فراسنجههای عملکردی و صفات مربوط به لاشه، در قالب طرح کاملا" تصادفی تعیین گردید. سطوح لیزین کل، شامل 6 سطح 00/1، 15/1، 30/1، 45/1، 60/1، 75/1 درصد بود که با فواصل ثابت 15/0، از سطح لیزین در جیره پایه تهیه شد. سایر اسید آمینههای ضروری به میزان مساوی یا بالاتر از نیاز های ارائه شده در (1994 NRC ) تامین گردید. در این آ...
Walls are vital in the structure, and give security to host. Wall as part of structure industrialised Building System (IBS). can be made a plunge two bearing non-bearing walls. Non-bearing walls delicate parcel boards. Segment board ought be, areas strength for light have great Noise Reduction Coefficient (NRC). This' exploration will likely make another segment from squandered material deliver...
The U.S. Nuclear Regulatory Commission (NRC) does not currently require full-scale physical testing of shipping casks as part of its certification process. Stakeholders have long urged NRC to require full-scale testing as part of certification. NRC is currently preparing a full-scale casktesting proposal as part of the Package Performance Study (PPS) that grew out of the NRC reexamination of th...
CONTEXT For more than 20 years, primary prevention of coronary heart disease has included strategies intended to improve overall serum lipid concentrations among youths. OBJECTIVE To examine trends in lipid concentrations among youths from 1988-1994 through 2007-2010. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional analysis of serum lipid concentrations among 16,116 youths aged 6 to 19 ye...
Present status of the neutrino magnetic moment solutions of the solar neutrino problem is reviewed. In particular, we discuss a possibility of reconciling different degrees of suppression and time variation of the signal (or lack of such a variation) observed in different solar neutrino experiments. It is shown that the resonant spin–flavor precession of neutrinos due to the interaction of thei...
It is well established that in commercial poultry operations today there are benefits from the routine use of higher levels of vitamins in feed than recommendations published in reviews such as NRC 1994. Today’s elevated levels not only help ensure simple deficiencies are rare, but also help the bird cope with the increased stress and disease challenge of commercial production. In addition, the...
این تحقیق به منظور بررسی اثرات سطوح مختلف پروتئین و پروبیوتیک در جیرههای غذایی جوجههای گوشتی تحت تنش گرمائی به روش فاکتوریل 3×3 در قالب طرح کاملاً تصادفی با 3 تکرار برای هر تیمار (540 قطعه جوجهگوشتی سویه راس) به مدت 42 روز بر عملکرد و سیستم ایمنی انجام گردید. برای این منظور تعداد 9 جیره غذایی بر اساس احتیاجات گزارش شده توسط انجمن تحقیقات ملّی تهیه شد که حاوی سه سطح پروتئین 90% ، 100% و 110...
The effect of3levels of methionine (NRC recommended, 5 percent more than NRC recommended and 10 percent more than NRC recommended) and 2 levels of fat (0 and 5 percent) on some economical traits (performance and carcass) of broilers using a 2x3 factorial experiment with completely randomized design based on two rearing stages, starter (0-3 wk) and grower (4-6 wk) was studied. ANOVA of the effec...
We present the review of clinical and experimental studies on pathogenesis neurorheumatological complications (NRC) in COVID-19. The influence systemic hyperinflammation caused by impaired innate immunity functioning neurovascular endothelium bloodbrain barrier, activation signaling pathways parainfectious autoimmunity central nervous system were analyzed. Hyperinflammation has been shown to co...
The wide range of applications of microwave technology in manufacturing industries has been well documented (NRC, 1994; Thuery, 1992). In this paper, a new way of joining fibre reinforced thermoplastic composites with or without primers is presented. The microwave facility used is also discussed. The effect of power input and cycle time on the heat affected zone (HAZ) is detailed together with ...
