It is often necessary to find a simpler method in different climatic regions to calculate reference crop evapotranspiration (ETo) since the application of the FAO-56 Penman-Monteith method is often restricted due to the unavailability of a comprehensive weather dataset. Seven ETo methods, namely the standard FAO-56 Penman-Monteith, the FAO-24 Radiation, FAO-24 Blaney Criddle, 1985 Hargreaves, P...
The Inter-Organisation Programme for the Sound Management of Chemicals (IOMC) was established in 1995 following recommendations made by the 1992 UN Conference on Environment and Development to strengthen cooperation and increase international coordination in the field of chemical safety. The participating organizations are the Food and Programme (UNDP) are observers. The purpose of the IOMC is ...
Genetically modified rice that contains beta-carotene, widely known as Golden Rice (GR), has not yet been introduced in any country. It was developed to address Vitamin A deficiency (VAD) in low-income rice consumers, but currently needs much more development and testing before it can be introduced into farmers’ fields. GR is the most famous biofortification effort undertaken with modern biotec...
Many local livestock breeds and minor species are in decline and may be lost because they cannot compete with high-yielding exotic breeds. Conserving these breeds is important: many have unique traits, such as hardiness and disease resistance, that are vital for future livestock production. One way to help ensure their survival may be to sell products from these breeds to high-value, specialist...
یکی از مهمترین مسائل در طراحی سازه های آبی، بررسی کیفیت آب، تعیین تأثیرات مدیریت آبخیز و حفاظت زیستگاه ماهیان، تعیین مقدار رسوبات معلق رودخانه ها می باشد. جهت برآورد بار معلق رودخانه ها از دو روش تجربی و رگرسیون آماری استفاده می شود؛ اما به دلیل تعدد روابط تجربی ارائه شده و ضرورت اصلاح آنها و ارائه ضرایب واسنجی جدید، در بیشتر موارد روش های رگرسیون آماری مورد استفاده قرار می گیرند. در روشهای رگر...
در این پژوهش 20 هیبرید ذرت دانه ای داخلی و خارجی از پنج گروه مختلف رسیدگی در دو فصل زراعی (1386 و 1387) در اسلام آباد کرمانشاه از نظر نیاز واحدهای گرمایی مورد مطالعه قرار گرفتند. به منظور ایجاد محیط های مختلف و امکان برآورد نیاز حرارتی هر یک از گروه ها، چهار تاریخ کاشت (اول اردیبهشت، 10 اردیبهشت، 25 اردیبهشت و 10 خرداد) در نظر گرفته شد. نتایج حاصل نشان داد که بر اساس نیاز حرارتی تا گلدهی، هر دو...

Rhabdomyolysis may result from various factors, namely trauma, exercise, medications, infections, endocrine disorders, congenital myopathies, and metabolic diseases. Among the latter, mitochondrial fatty acid b-oxidation (FAO) defects frequently cause recurrent rhabdomyolysis. FAO disorders are recessively inherited and have a combined incidence of 1:9,300, estimated after implementation of new...
Abnormalities of fatty acid metabolism are recognized to play a significant role in human disease, but the mechanisms remain poorly understood. Long-chain acyl-CoA dehydrogenase (LCAD) catalyzes the initial step in mitochondrial fatty acid oxidation (FAO). We produced a mouse model of LCAD deficiency with severely impaired FAO. Matings between LCAD +/- mice yielded an abnormally low number of L...
