Research ArticleOpen accessIn the keywordsEstimation of Pan Coefficient using M5 Model TreePakorn Ditthakit, Chaiyuth ChinnarasriProblem statement: Pan Evaporation has extensively been used for estimating reference Evapotranspiration (ETo) due to its simplicity, low cost, ease of data interpretation and application and suitability for locations with limited availability of meteorological data. With this method, the pan coefficient (Kp) is a key element to be determined as well as the pan Evaporation (Ep) data. Approach: This study … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Morphometric Traits to Estimate Live Body Weight of South African Bapedi SheepThabang Sako, Jones Ng’ambi, Thomas Raphulu et al.This study was carried out for the estimation of Body Weight (BW) of bapedi sheep from Body Length (BL), Sterna Height (SH), Heart Girth (HG), Height at Withers (WH), Rump Height (RH) and Head Length (HL). Correlation and regression were used. Correlation displayed that body weight is highly positively associated (p<0.01) with WH and HG in males while for females, … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 26 Jun 2024 · 5,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Chlorophyll-an in a Small Reservoir by Landsat 7 ImageryMaryam Ghashghaie, Kaveh Ostad-Ali-Askari, Saeid EslamianChlorophyll-a (chla) is a source of water pollution. Monitoring the quality of water in reservoirs is necessary to take any action for protecting the water quality. Traditional methods of sampling are usually costly and time consuming. Also they need skillful labors and some areas are out of reach or sampling at those areas is dangerous. Remote sensing technology could solve … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 8,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractFatigue Life Prediction of Screw Blade in Screw Sand Washing Machine under Random Load with Gauss DistributionJie Gong, Yun-Fei Fu, Wen Xia et al.The purpose of this study is to present a new method for estimating the fatigue life of the screw blade in the screw sand washing machine. To ensure the accuracy of numerical simulation, the loading area and the value of load are determined by means of the theoretical analysis. To ascertain the location of the stress peak and stress range, … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 22 Dec 2016 · 8,005 accessesView PDFCite
