Study of the thermo-hydro-mechanical characteristics of prismatic compressed earth specimens from two brick quarries in the city of Abéché, Chad
The study focuses on the thermo-hygro-mechanical characterization of prismatic samples compressed earth specimens (CECs). Firstly, various sampling sites were located in order to identify them. Thus, the 4 × 4 × 16 cm3 specimens were used for the mechanical tests and the absorption test. In addition, 4 × 5 × 8 cm3 specimens were used for the thermal test. The wood ash content was varied from 0 to...

Preparation of soft-hard X-ray absorption nanocomposites using PbS, PbSe coated on SWCNTs based polyaniline
The dangers of heavy wave radiation such as X-rays are well known, and current coatings are inefficient, heavy, and expensive. The above project has attempted to provide lightweight, highly efficient, and cheaper absorbers. PbS and PbSe nanoparticles (NPs) were coated successfully on functionalized single wall carbon nanotubes (F-SWCNTs) by chemically and thermochemically reactions. Then, their nanocomposites with...

Estimating the depth of basement rocks within the Guzabure and Gudumbali area of the Nigerian sector of the Chad basin using a spectral analysis technique
This research aims to estimate the depth of basement rocks in the Guzabure and Gudumbali areas with longitude (12.3° to 13.0° N) and latitude (12.3° to 13.3° E) within the Nigerian sector of the Chad basin using aeromagnetic data. The quantitative data interpretation employed the spectral analysis approach and Oasis Montaj 6.4.2 software. Minimum curvature was applied in gridding the data to produce a...
