Transistors made of thin layers (Thin Film Transistor: TFT) are used primarily for the realization of active matrix flat panel displays liquid crystal. They constitute the basic element of a specific part of electronic ...

A photovoltaic (PV) output power depends nonlinearly on the climatic changes such au solar irradiation and temperature, there exists a unique maximum power point (MPP). Thus, a maximum power point tracking (MPPT) controller ...

A Cosmic string model based on Seiberg-Witten non commutative geometry is constructed. Black holes solutions are determined and the Hawking radiation temperature near the horizon is also derived

Quantum chemical calculations based on DFT method were performed on azomethine compound: PhN=N-C (COCH3) =NC6H4Y {Y = NO2 (SB1)}used as corrosion inhibitor for mild steei in acid media to determine the relationship between ...

The objective of this work is a study of the structural properties (lattice parameters, total energy, bulk modulus) and electronic properties (band structure, density of states) of rare earth monochalcogenides LaX (X=Se, ...

The strurural, electronic and elastic properties of rare-earth monochalcogenides EuX (X=Se, Te) were investigated with the full-potential-linearized-augmented plane wave (FP-LAPW) based on density functional theory (DFT). ...

Diclofenac sodium (DS) is considered as priority anti-inflammatory pollutant because of its presence in water. In this paper, we addressed the issue of using organo-K10 montmorillonite as adsorbent of DS to reduce its ...

Dans ce présent travail une étude a été effectuée, pour améliorer l’efficacité des émetteurs de chaleur (radiateurs) lors du renouvellement d’air des locaux d’habitation. Un nouveau système économique du système de ventilation ...

Many research studies have been performed on forced convection (active) solar dryers for fruit, vegetables and plants. A short survey of these showed that applying the forced convection solar dryer not only significantly ...

Ce papier porte un modèle d’étude d’une machine à absorption tritherme, opérant au couple H2O/LiBr, alimentée par un capteur solaire plan. Le modèle mathématique est basé sur les principes et les lois de la thermodynamique ...
