Historically, the oceans were considered limitless and thought to harbour enough fish to feed an ever-increasing human population. However, the demands of a growing population, particularly in poorer countries, now far outstrip the sustainable yield of the seas. At the same time as fishing has become more industrialised, and wild fish stocks increasingly depleted, aquaculture production—fish an...

فرسایش خاک ازجمله فرآیندهایی است که منابع آب و خاک یک کشور را مورد تهدید قرار می دهد. فرآیند فرسایش بسیار پیچیده است و عوامل زیادی در آن دخیل بوده که مهمترین آنها عوامل اقلیمی، شیب زمین، پوشش گیاهی، مدیریت و نحوه کاربری اراضی می باشد. به دلیل عدم وجود اطلاعات در منطقه از بین روش های تجربی، چهار روش mpsiac ،epm،fao، blm انتخاب و ارزیابی این چهار مدل در یکی از حوزه های استان کهگیلویه و بویر احمد-...

FAO has as its mandate the raising of levels of nutrition and standards of living and ensuring humanity's freedom from hunger by promoting sustainable agricultural development and alleviating poverty. FAO is dedicated to promoting agriculture, nutrition, forestry, fisheries and rural development to achieve the World Food Summit goal of eradicating hunger. FAO provides advice and assistance to o...

Cold exposure and β3-adrenergic receptor agonist (CL316,243) treatment induce the production of beige cells, which express brown adipocytes(BA)-specific UCP1 protein, in white adipose tissue (WAT). It remains unclear whether the beige cells, which have different gene expression patterns from BA, express BA-characteristic fatty acid oxidation (FAO) proteins. Here we found that 5 day cold exposur...

Abstract This study aimed to accurately estimate daily wheat evapotranspiration using two remote sensing algorithms, Surface Energy Balance System (SEBS) and Algorithm for Land (SEBAL), in central Khuzestan province during 2019–2020. The results of algorithms were compared with lysimeter (as a direct method), FAO-Penman–Monteith (FAO-PM), temperature-based methods (Hargreaves-Samani Blaney-Crid...

The present study develops ArcMap models to implement the following three methods: FAO-56 Penman–Monteith (FAO PM), Hargreaves–Samani (HS) and Hansen, with former used as a reference. Moreover, implementing statistical indices (RMSD, MB, NMB) are also created. purpose is threefold, follows: investigate variability in daily mean reference evapotranspiration (ETo) for Decembers Augusts during 201...
