yield prediction before harvesting is one of the tools in order to planning food production supply in future.yield prediction was carried out for wheat(triticum aestivum) using different meteorological variables with agrometeorological indices in hamedan district during 2003-04 and 2004-05. according to correlation coefficients, standard error of estimate as well as relative deviation of predic...

Abstract: The supersolidus liquid phase sintering characteristics of commercial 2024 pre-alloyed powder was studied at different sintering conditions. Pre-alloyed 2024 aluminum alloy powder was produced via air atomizing process with particle size of less than 100 µm. The solidus and liquidus temperatures of the produced alloy were determined using differential thermal analysis (DTA). The sinte...

Rwanda has experienced high temperature rising phenomena over the last decades and hence, highly vulnerable to climate change. This paper examined spatial temporal variations of daily maximum minimum surface air (Tmin Tmax) diurnal range (DTR). It studied variables at monthly, seasonal annual time-scales from 1961 2014. The study applied various statistical methods such as ordinary least-square...

The interaction between sea and atmosphere has profound effects on the regions climate. Meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. Because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surfa...

Several studies indicate that the hot season is lengthening at expense of intermediate seasons, and extreme events are becoming more intense spread out over time. What situation in a climate described as very hot? This work aims to examine evolution minimum maximum temperatures period from June September during 1951–2010 Bechar region, which classified among hottest world located south-west Alg...
