Large-scale photovoltaic (PV) power plants may affect the hydrological cycle in all its components. Among various components, evapotranspiration is one of most important. As a preliminary step for assessing impacts PV on evapotranspiration, this study, we performed an evaluation study methods estimating reference (ETo). FAO and ASCE recommend Penman–Monteith (PM) method estimation ETo when data...

Resumo A radiação solar é uma variável climatológica amplamente utilizada em estudos climáticos e pode ser mensurada por meio de estações meteorológicas. Devido ao alto custo difícil manutenção dos equipamentos mensuração, possível estimá-la a partir modelos matemáticos. Assim, o presente estudo objetivou calibrar validar os parâmetros da equação ångström-Prescott Hargreaves & Samani para r...

We evaluated and compared the performance of simulated Angström-Prescott (AP) Hargreaves-Samani (HS) models on monthly annual timescales using generalized datasets covering entire West African region. The fitted AP model yielded more efficient parameters a = 0.366 b 0.459, whereas HS produced 0.216 coefficient based an timescale, which is suitable in region to coefficients recommended by Food A...

abstract in this study, impact of climate change on net irrigation requirement (in) and yield of wheat using cgcm3 climate projection model, one of the aogcm models, in behshahr area is evaluated. changes in temperature and precipitation were simulated run under the ipcc scenario a2 for 2011-2040, 2041-2070 and 2071-2100 periods. this work was done by using statistical and proportional downscal...

Bleomycins are tumor seeking antibiotics that are widely used in cancer chemotherapy (Fig. 1). It is believed that bleomycin antibiotics interfere with DNA as false nucleotides, assuming the dithiazole moiety acts like a purine base [20]. It has been shown that labeling of bleomycin with bi/trivalent radioisotopes can produce pharmacologically active compounds carrying a diagnostic and/or thera...

Accurate estimation of reference evapotranspiration is essential for agricultural management and water resources engineering applications. In the present study, ability precision three artificial intelligence (AI) models (i.e., Support Vector Machines (SVMs), Adaptive Neuro-Fuzzy Inference System (ANFIS) Categorical Boosting (CatBoost)) were assessed estimating daily (ET0) using limited weather...
