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...

This study aims to identify the digital transformation and human performance, as well as to determine the extent to which digital transformation affects human performance in its dimensions (training, discipline, and creativity) at Sonelgaz company in Ain Temouchent. To answer the research problem and sub-questions, the descriptive and analytical approach was adopted using a questionnaire distributed to a sample of 60 employees of the company. The data was analyzed using SPSS version 21. The r...

Through this study, we aim to explore students' perceptions of cheating in examinations. A sample of 50 individuals was randomly selected from students in the Department of Social Sciences at Belhadj Bouchaib University, Ain Temouchent. Considering cheating as a prevalent issue with negative implications for educational quality and equal opportunities among students, we utilized a descriptive-analytical approach to address the following main question: How do students in the ...
