The main objective of this study is to conduct a controlled thermal investigation small Parabolic Trough Concentrator (PTC) under real climatic conditions for El-Oued region on 16/03/2018, where the water was adopted as heat transfer fluid. One-dimensional and transient energy balance equations have been analyzed, simplified then programmed with Matlab code. What distinguishes precise tracking ...

Abstract The characterisation of traditional barley varieties from North Africa is promising with respect to detect traits linked resilience drought. Nine Algerian comprising the economically relevant local landraces Saïda183 and Tichedrett were genotyped by random amplifying polymorphic DNA (RAPD) Simple Sequence Repeat (SSR) markers get insight into their phylogenetic relationship compare eff...
