Résumé Un avantage majeur des systèmes radars haute fréquence (HF) est qu'ils ne sont pas affectés par la météo, les nuages ou l'évolution des conditions océaniques. En plus des tâches courantes de détection de cible ...

We explored in this study the crystal structure determination of Z-3N(2-Ethoxyphenyl), 2-N’(2-Ethoxyphenyl) imino thiazolidin-4-one. The crystal structure has been determined by X-ray diffraction. The compound crystallizes ...

In this work, a co-doped Bi-Zn-TiO2 photocatalist is synthesized by an original synthesis route of layered double hydroxide followed by heat treatment at 670°C. After characterization the photocatalyst efficiency is estimated ...

We studied Full Heusler materials using the method of plane waves full potential linearized augmented (FP- LAPW ) based on density functional theory (DFT ) implemented in the WIEN2k code, to determine the structural ...

The aim of this study is to evaluate effectiveness of the adsorbent, which is in our case activated carbon prepared from the sawdust; grapes cores and apricots cores in order to remove or eliminate the diamond green B; ...

The commercial activated carbon of Merck was treated with KOH (10%), H2SO4 (96%) and K2CO3 (30%) and the commercial activated carbon of Riedel de Haen with NaOH (2N), citric acid (1M) and ammonium oxalate (10%) at different ...

This present work concerns the development of an indirect method to produce chromium carbide coatings known for their properties of wear, corrosion and oxidation resistance and that by the combination of a treatment of ...

The objective of this thesis is the numerical study of the dispersion of a passive scalar urban simplifies using the Shensi computer code by comparing the experimental results from the University Hamburg (Experience in ...

The rapid development of technologies related to microprocessors, already achieves several GHz, while reducing the size of microchips. Therefore, the flux density of heat generated by these circuits is constantly increasing, ...
