This work describes a thesis that is divided into two chapters. In the first chapter, a synthesis of novel benzimidazolium salts is presented as N-heterocyclic carbene precursors (NHCs), along with the synthesis of their ...
The reinforcement of damaged structures, by bonding composite patches, is a promising and beneficial repair technique, especially in the field of air transport. This method consists in reinforcing preventively damaged ...
The extreme volatility of volatile organic compounds (COVs) molecules gives them the ability to diffuse far from their source of emission, resulting in direct and indirect impacts on ecosystems and human health. The exposure ...
This thesis focuses on the synthesis of new porous coordination polymers based on pyromellitic acid. The crystal structures of the hybrid materials have been solved from single-crystal X-ray diffraction data and the ...
Aromatic compounds containing azo or azoxy functions are widely used in the chemical industry as color pigments, food additives, indicators, initiators of free-radical reactions and therapeutic agents. The treatment of ...
La présente étude s’inscrit dans le champ de l’analyse du discours. Son objet d’étude est le discours de Tariq Ramadan proféré dans deux contextes interactifs différents à savoir : les débats et les conférences. Notre ...
This thesis is a study of a vapor ejection refrigerating machine. The study consists in developing a program allowing the sizing of the ejector taking into account the characteristic data of the three heat sources (the ...
Currently, cell materials are used in various sectors, such as automobile, transport and aerospace. A cell solid is a solid consisting of a connected network of solid links and/and plates forming the edges and the faces ...
This work concerns the application of the approach of supersymmetry in quantum mechanics (SUSYQM) to solve the one-dimensional Schrödinger, Klein-Gordon and Dirac equations for a particle of position-dependent mass subject ...
In order to improve the biodiversity knowledge of Algerian springtails, a hundreds of samples were collected from many forests, caverns and caves meadow, in different bioclimatic stages during the years 2018-2020. 85 species ...
In this work, two parts have been developed. The first is devoted to the synthesis, characterization and theoretical study of new meso-substituted dipyrromethanes. These compounds have been synthesized by a double ...
The reduction of socio-spatial disparities between the districts of the city of Boussaâda, can
takes at least two paths, one towards the relocation of people to weave a social mix, the other relies on the
strengthening ...
Tamoxifen, a selective estrogen receptor modulator acts as an anti-estrogen in ER+ breast cancer. It inhibits competitively the binding of estradiol to their receptors, the efficacy depends on its active metabolites, ...
This study was designed to evaluate the antioxidant, antidiabetic and anti-inflammatory effects of n-BuOH extract of Capparis spinosa in streptozotocin (STZ)-induced diabetic Wistar rats in the case of pancreatic and ...
In the past, production has been simple, but as time, with the opening of the global market, companies
have begun to implement various initiatives, including the adoption of globalization strategies,
diversification of ...
In this work, we have numerically analyzed the problem of heat transfer by laminar and permanent natural convection in an eccentric annular space filled with a hybrid nanofluid. The two internal and external cylindrical ...
The aim of this thesis is to present a novel mode of convergence of sequences of random variables, and to establish a better complete convergence rate's for kernel estimators of functional characteristic’s of unknown ...
The present study focused on the phytochemical investigation and the evaluation of the
antioxidant activity of two plants: Anagallis monelli ssp. linifolia (L.) (Primulaceae) and Arenaria
cerastioides (poir.) (Caryophyllaceae). ...
The objective of this study is to evaluate the relationship between the chemical and biological composition of 8 bee pollen samples and the antioxidant, anti-inflammatory ant anti-allergic potencies. Therefore, the samples ...
This thesis work focuses on the thermal performance of biosourced materials of plant origin with the aim of using them as thermal insulation in buildings. We have studied their use, particularly in subtropical climates. ...
