Cu2ZnSnS4 (CZTS) thin films were prepared by directly sputteringCu (In,Ga)Se2 quaternary target consisting of (Cu: 25%, Zn: 12.5%, Sn; 12.5%and S: 50%). The composition and structure of CZTS layers have beeninvestigated after annealing at 200 0C, 350 0C and 500 0C under vacuum. Theresults show that recrystallization of the CZTS thin film occurs and increasingthe grain size with a preferred orie...

his research focused on studying the variability of solar radiation and temperature under climate change in Ibadan metropolis. In study, spatial distribution, temporal variations, annual estimation prediction radiation, minimum maximum data Metropolis was collected. A Long Short-Term Memory Neural Network (LSTM-NN) model developed for using time-series obtained. An ARIMA further to compare vali...

abstract the climate change was known to force local hydrology, through changes in the pattern of precipitation, temperature and the other hydrological variables. in this research, the impact of global warming on maximum and minimum temperature, precipitation and evapotranspiration (wheat, corn, tomato and sugar beet) of kashafrood basin under two climate change scenarios (a2 and b2), and the o...

zayanderoud basin is one of the important agricultural areas in country level because of climatic variety and resuscitative water of zayanderoud river. since frost phenomenon especially late spring frost incurs great damages on fruit trees and agricultural products of this region, it is necfessary to study frost in this basin.in this research, the intensity of frost during cold period and sprin...

Sundarijal River supply drinking water in Kathmandu city, Nepal and to study the nitrate concentration, 10 different sample from locations of was taken. The method for removal presence tested using hydroxylamine hydrochloride dose at 25±2 0C with 35 minutes contact time. Samples reduction increase increasing dosages, up certain limit. That mean 0.5g, 0.6g 0.8g dosages hydrochloride, not observe...

This article examines the reduction of speedand heat loss in passenger compartment an electric vehicle (EV) when installing additional thermal insulation gasket on doors. The study was conducted conditions extremely low outdoor temperatures that occur winter season northern and arctic regions. To conduct a series observations, doors car were equipped with (second) heat-insulating rubber gasket....

Stress Corrosion Cracking (SCC) is known as a trigger for material failure, especially in Dissimilar Metal Welding (DMW). Although DMW promises wide application structural design, it found that there high SCC mitigation making prone to failure. Capacitor Discharge (CDW) one of the best dissimilar metal welding methods. This article observes weld joints CDW ASTM A36 and SS 316L against phenomeno...

Management of organic matter and micronutrients is very important for the sustainable improvement soil health. Poor usually results in lower availability zinc (Zn) plants. Such deficiency Zn causes a significant decrease growth yield crops. The need at current time to balance application amendments with achieve optimum crop yields. Thus, study was conducted investigate wheat, using compost as m...
