The ground water Hamma rich in calcium and bicarbonate likely to deposit the tartar and subsequently lead to the obstruction of the pipes and the seizing of the stopping devices in addition to the financial losses resulting ...

The objective of the works presented in this thesis is the development of new access routes to a variety of nitrogen polyheterocyclic compounds containing in their structures a phthalazine nucleus fused to other cycles ...

This research was aimed to further evaluate the potential of biosorption technique by exploiting locally available biosorbents undergoing minimum pretreatment steps. The toxic metal of interest for biosorption in this work ...

The main objective of this work was to synthesize original metal complexes of original tetradentate dianionic ligands of the type (O,E,E,O), with E = N or S with different steroelectronic properties and to examine the ...

The work presented in this thesis contributes to the valorization of both Algerian medicinal plants (Crataegus oxyacantha L. (Rosaceae) and Cytisus triflorus L'Her. (Fabaceae) by characterizing them by a phytochemical ...

This work is devoted to phytochemical and biological studies of two Algerian species, Pituranthos battandieri Maire (Apiaceae), an endemic plant of the Algerian-Moroccan Sahara and Frankenia thymifolia Desf. (Frankeniaceae) ...

The search for compounds of therapeutic interest more and more effective with the minimum of possible adverse effects remains a challenge for scientists and pharmaceutical players. In this thesis, we first synthesized a ...

The aim of our study was a double environmental aspect, the valorization of a composite material and the implementation of a device for purifying polluted water. a series of experiments was made to prepare the sulfonated ...

This manuscript encloses two principal parts: In the first part, We report the use of three metals for debenzylation of protected tetrazoles: indium, magnesium and zinc, comparing the process of using metals, and taking ...

This work is a contribution to electrochemical synthesis of four organic conjugated polymers. The four materials studied, poly(2,7-bis[(thien-2-yl)cyanovinyl]-9,9-dipentylfluorene) (PFPT), poly(2,7-bis[(2,3-dihydrothieno ...
