Schottky diodes have been made on virgin n-type monocrystalline silicon annealed by various optical thermal processes including lasers and incoherent light heat-pulses. The electrical characteristics of the diodes have been measured as a function of…

L'étude de faisabilité et la conception optimale d'un système énergétique hybride pour fournir de l'énergie électrique à un site éloigné de M'Sila est examinée dans ce papier. Le but de ce document est de concevoir et de simuler un mini-réseau…

In this paper we report the SrAl2H2 electronic properties which is a Zintl phase hydride in frame of the Density Functional Theory ‘DFT’ using the plane wave and pseudo potential method. We discuss the chemical bond nature using total and partial…

Le kaolin purifié et traité par HCl 0,4 M, a été utilisé comme adsorbant pour éliminer le manganèse contenu dans les eaux de rejets. La caractérisation physicochimique a montré que le kaolin de Guelma est constitué en majorité de silice et d’alumine.…

In this work, the removal of two cationic dyes {greenmethyl and basicyellow 28} by electro coagulation using aluminium as anode and stainless steel as cathode was studied. First, the effect of the most important parameters {current intensity, initial…

The energy balance components of a greenhouse as well as the greenhouse design may strongly impact the greenhouse energy. Few studies were devoted to the description of the energy balance components of a greenhouse located in the semi arid region of…

The information about solar radiation is limited in space and time at different local regions around Algeria due to the cost of instrumental requirements. Therefore, a number of models have been developed in different regions to estimate incident…

The hybrid solar thermal (PV/T) offer an attractive option because the absorbed solar radiation is converted into heat and electricity. The ongoing conflict is well known between temperature and photovoltaic systems by the increase in solar…

This research lies within the scope of environmental research for seeking solutions for the optimizations of energy in the electrical supply network ADE- Adrar (Algérienne des Eaux d’Adrar/Algeria). Indeed, the principal aiming of this research is…

Old buildings consume a lot of energy and no longer comply with thermalregulations, which creates interior discomfort. Our work consists ofhighlighting the effect of the rehabilitation of the building on energy savings and thermal comfort. The case…
