This paper presents a techno-economic analysis and environment assessment of hybrid photovoltaic (PV), wind turbine (WT), diesel genset (DG) with pumped hydro storage (PHS) for rural microgrid system. The is carried out case study Mentawai community load demand 165.44 kWh/day at peak 20.46 kW. Homer simulation results show that there are eight feasible configurations, which the optimal system c...

elm leaf beetle, xanthogaleruca luteola, is a serious pest (particularly at its larval stage) of elm trees in many areas. the existence of three important enzyms namely: ?-amylase, ?- glucosidase and ?-glucosidase in the midgut of the insect at its larval stage was investigated. optimum activity for ?-, ?-glucosidase and ?-amylase was recorded at phs 5.0, 6.0 and 6.0 against p-nitrophenyl-?-d-g...

A previously described method for evaluating computer programs for electrocardiographic (ECG) interpretation was applied to Version D of the Public Health Service (PHS) program and to the Mayo Clinic program of 1968. Staff cardiologists found agreement with the results of the PHS program in 45.5% of 1150 unselected tracings. Clinically significant disagreements based strictly on application of ...

Pre-harvest sprouting (PHS) in wheat (Triticum aestivum L.) occurs when physiologically mature kernels begin germinating in the spike. The objective of this study was to provide fundamental information on physicochemical changes of starch due to PHS in Hard Red Spring (HRS) and Hard White Spring (HWS) wheat. The mean values of α-amylase activity of non-sprouted and sprouted wheat samples were 0...

Solar energy is currently dispatched ahead of other renewable sources. For the first time, this study presents a concept exploiting temporary–periodical runoff discharge in Shire River. Pumped hydro storage–photovoltaic plant (PHS–PV) was optimized to satisfy all-day peak electricity demand Malawi. The effect varying net head on PHS system both generation and pumping operation modes investigate...

Phytohormones (PHs) play crucial role in regulation of various physiological and biochemical processes that govern plant growth yield under optimal stress conditions. The interaction these PHs is for survival stressful environments as they trigger signaling pathways. Hormonal cross initiate a cascade reactions which finely tune the architecture help to grow suboptimal Recently, studies have hig...
