At the end of this lesson, in which we discussed the strategy of transitioning towards renewable energies to achieve security, we would like to highlight the analysis and explanations provided on the importance of energy transition in light of the challenges facing the country at the energy and economic levels. We began this research by presenting the concept of renewable energies and the importance of these energies at the global level, where we reviewed the types of renewable energies such ...

The present work is a study of physical properties (structural, electronic, optical, and thermoelectric...etc.), alloys based on bismuth, and lanthanides. This will allow us to define the problem of phase stability as well as the problem of the role of electrons in this stability using the method of augmented and linearized plane waves at total potential (FP-LAPW) implemented in the Wien2k code. Materials based on bismuth and lanthanides have been intensively studied because of their nu...

From an ecological and economic point of view, the present research aims to contribute to the valorization of calcined clays as supplementary cementitious materials (SCMs) in the composition of cementitious mortars. So, the objective of this study is to evaluate the influence of three SCMs which are: metakaolin (MK), calcined sediments (VC) and brick powder (PB) (added by substitution of cement with different dosages, ranging from 10 to 30%) on the physic-mechanical and durability p...

This contribution reports a simple and environmentally friendly method for synthesizing silver nanoparticles (AgNPs) using aqueous leaf extract of Mentha aquatica. The impacts of various operational parameters such as leaf extract dosage, solution pH, temperature, and contact time on the formation of AgNPs were examined in detail. Data revealed that 5% v/v Mentha aquatica leaf extract, a pH of 9.0, a temperature of 18°C, and an incubation time of 60 minutes yielded optimal nanoparti...

Diabetes is a chronic disease affecting an increasing number of people worldwide. Its management requires continuous monitoring of blood glucose levels with precise insulin administration, tasks often burdensome for patients. With the increasing prevalence of diabetes, there is a need for a non-invasive and controlled method of managing it, offering diabetic patients a more comfortable and secure quality of life. It is in this context that our project "InsuVida Techno" takes on its full ...

Introduction: Improving the filtration efficiency of electrostatic precipitators requires an understanding of the physical phenomena involved in their operation. Numerical methods have also enabled significant progress to be made in the sizing and general architecture of any filtration system. However, the operation of these filters is not always stable, and fluctuations in filtration efficiency frequently occur, necessitating the implementation of a monitoring system and permanent qua...
