contracts in our foreign trade.
These contracts are considered us effective partners for our traders because of the guarantees offered by
them. They ensure goods and many importer equipment against different risks of transport (maritime, air
and land) and are important certificates requested at the opening of a bank credit because of the guarantees
offered by them to the banks. They also accompany the exporter during the different stages of the export
transaction and facilitate obtaining financing for its exports.
Their impact is not limited on economic operators, but it also extends to the national economy.
We found that this type of insurance appears limited. It affects a minority of traders. It should be extended to
a larger number. This will demand concerted efforts between governments, insurance companies and
different stakeholders in the field of foreign trade.Diplôme : Doctorat En ligne : ../theses/droit/AABB4186.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10688 واقع تأمين التجارة الخارجية في الجزائر [texte imprimé] / كریمة عباس, Auteur ; أحمد رحال, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2017 . - : 370 ورقة. ; 30 سم.

Index. décimale : 530 Physique Résumé : In this investigation the author presents a numerical study of heat and mass
transfer by natural convection in an annular space delimited by two horizontal
and confocal elliptical cylinders filled with a Newtonian fluid in laminar and
steadystate regime. The phenomenon of thermosolutale convection is governed
by the equationsof mass conservation, equations of momentum, energy and
concentration expressed in a coordinate system called "elliptical" to facilitate
writing boundary conditions and transform the area into a curved rectangular
field. The two elliptical walls of the isothermal enclosure, with a constant
concentration, T1 and C1 to the inner wall, T2 and C2 to the outer wall, with T1>
T2 and C1> C2.
Using the Boussinesq approximation and the vorticity-stream function
formulation, we study the influence of the main control parameters: the Rayleigh
number (Ra), the Lewis number (Le), the Prandtl number (Pr), the buoyancy
ratio (N) and the internal volume of eccentricity (e1) on the structure of the flow
and, on heat and mass transfer rates.Diplôme : Doctorat en sciences En ligne : ../theses/physique/BOU6836.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10128 Contribution a l’etude des transferts de chaleur et de masse au sein d’un espace annulaire elliptique d’axe horizontal [texte imprimé] / Abdelkarim Bouras, Auteur ; Mahfoud Djezzar, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2015 . - 105 f. ; 30 cm.

activity NMR ?????????? ??????????? ???????? ????????? ?????? ?????????? ?????? ?????? ???????Index. décimale : 540 Chimie et sciences connexes Résumé : In the first part, a new variety of adamantyl chalcones was efficiently prepared by ClaisenSchmidt reaction of 4-adamantyl acetophenone with a series of aromatic aldehydes in good
yields. Their structures were confirmed by spectroscopic data, and the relative configuration
of compound 3d was confirmed by X-ray crystallography. All synthesized chalcones were
tested against a panel of Gram-positive and Gram-negative bacteria and pathogenic fungus.
They displayed a strong antibacterial activity against Enterococcus faecali 29212,
Pseudomonas aeruginosa ATCC27853, Escherichia coli, as well as an interesting antifungal
activity against Candida glabrata ATCC 90030. The effect of these compounds was also
tested in vitro as antitumor on Miapaca2 cells. The compounds also showed anticancer
activity against human pancreas cancer cell MiaPaca2.
In the second part, several thiazolyl-pyrazoline derivatives were synthesized by reacting
substituted 3, 5-diaryl-1-thiocarbamoyl-2-pyrazolines with phenacylbromides. The structures
of the synthesized compounds were confirmed by IR, 1H NMR, 13C NMR, and MS spectral
data. Their antimicrobial, anticancer activities and cytotoxicity were investigated. A
significant level of antimicrobial activity and anticancer activity against A549 human lung
carcinoma cell line and low cytotoxicity were observed.Diplôme : Doctorat En ligne : ../theses/chimie/TAB7068.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10533 Synthèse de Chalcones adamantylées, de dérivés Thiazolylpyrazolines et évaluation de leurs activités antimicrobienne et anticancéreuse.
