BACKGROUND Accurate data on dietary habits are crucial for understanding impacts on disease and informing policy priorities. Nation-specific food balance sheets from the United Nations FAO provided the only available global dietary estimates but with uncertain validity. OBJECTIVES We investigated how FAO estimates compared with nationally representative, individual-based dietary surveys from ...
برای برآورد تبخیرتعرق گیاه مرجع (et0) روش ترکیبی فائو ـ پنمن ـ مانتیث (f-p-m)، به منزلة روشی استاندارد، جهت ارزیابی نتایج سایر روشهای تجربی در دو گروه دمایی ]بلانی ـ کریدل (b-c) و هارگریوز ـ سامانی (h-s)[ و تشعشعی ]جنسن ـ هیز (j-h) و تورک (tc)[ استفاده میشود. در این تحقیق، با استفاده از دادههای ایستگاه هواشناسی کشاورزی هاشمآباد گرگان، واقع در اقلیمی نیمهخشک، مقادیر et0 برآوردی با مقادیر رو...
the fao penman - monteith (f-p-m) method is now broadly accepted as the standard for estimating the reference evapotranspiration (et0). the method is also now used for evaluating the temperature-based [blaney-criddle (b-c) and hargreaves-samani (h-s)] and radiation-based [jensen-haise (j-h) and turc (tc)] methods. the objective was to compare the et0 estimated by the b-c, h-s, j-h, tc methods w...
Bu çalışma, dinamik sulama programıyla sulanan II. Ürün silajlık mısırın (Zea mays) verim ve morfolojik özelliklerine etkisini belirlemek amacıyla Balıkesir ili Manyas ilçesi ekolojik koşullarında 2016 yılında yürütülmüştür. Dinamik programının oluşturulmasında FAO Penman Monteith yönteminden yararlanılmıştır. Günlük iklim verilerinden hesaplanan evapotranspirasyon (ETo) değerleri bitki katsayı...
Reference evapotranspiration (ET0) is essential for agricultural production and crop water management. The recent climate change affecting the spatiotemporal variation of ET0 in eastern China continues to still be less understood. For this purpose, latest observed data from 77 meteorological stations Anhui province were utilized determine variations by use Penman–Monteith FAO 56 (PMF-56) model....
introduction: evaporation and evapotranspiration are two major components of hydrological cycle which are very important for agricultural studies as well as water resources management. so far, various methods have been addressed for the estimation of daily reference crop evapotranspiration (et0). among them, fao penman-montieth 56 (pmf-56) (allen et al., 1998) is widely used as a standard metho...
OBJECTIVE To determine whether the obesity-related decrement in fatty acid oxidation (FAO) in primary human skeletal muscle cells (HSkMC) is linked with lower mitochondrial content and whether this deficit could be corrected via overexpression of peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1alpha). RESEARCH DESIGN AND METHODS FAO was studied in HSkMC from lean (BM...
of an integrated knowledge-based machine-aided translation system called PANQLOSS. The ISI-specific work includes the development of English sentence generation and sentence planning capabilities and the construction of an Ontology of concepts to act as the semantic lexicon for all modules of the system as a whole. In addition, we continue to enhance Penman's existing generation technology, to ...
