Index. décimale : 550 Sciences de la terre Résumé : tract The main purpose of this work was the characterization of minerals associated with evaporite Triassic formations of the Setifian High Plains.
In the north eastern of Algeria and between the two barriers of mountains, Hodna in
South and Babors in North, situated a vast plains, commonly known as the Setifian High
Plains. This zone occupies the central part of the wilaya of Setif, and it's a part of the externe areas of the Alps, eastern Algeria, between the Tellian slicks in the North and the forward land autochton in the South. It is considered a closed continental basin, filled by Neogene and Quaternary deposits.
The genesis of evaporite deposits caused by the lagoon system that prevailed in the Triassic era with an arid climate and a high degree of evaporation which led to the precipitation of ions, Ca ++ So3--, Na +, Cl-, giving salt deposits and gypsum.
The spatial distribution, and the surface movement of the Triassic evaporite formations in the Setifian High Plains would probably caused by the phenomenon of overlapping slicks of alloctons to the south. We find five (5) evaporite formations dating from the Triassic; Guellal, Koudiat el Bassour, Methgoub Ras, Draa El Djebbas and Jebel el Garsa.
The principal minerals related to Triassic outcrops are represented essentially by evaporite deposits (gypsum and rock salt) .The particularity is marked by the presence of metallic minerals (iron and copper) in the blocks associated with evaporites Koudiat El Bassour.
The iron mineralization associated with copper, is hosted mainly in carbonate rocks, considered by the ancient writers as an infraliasiques formation. The morphology of the mineralized bodies is characterized essentially by a vein shape and stockworks type.
The mineralogical characterization by XRD and metallographic microscopic observation shows that the mineralization is usually oxidized brown-black (hematite, goethite, limonite) developed on iron carbonate (siderite, ankerite) associated with a few sulphides (chalcopyrite covellite, pyrite) and copper carbonate (malachite).
Gypsum deposits are widespread in all the Triassic outcrops of the region; it comes in four (4) forms (fibrous, crystalline, microcrystalline and grainy). The Gîtologics characters, the mineralogical characterization by XRD and chemical analysis by fluorescence X show that the gypsum is characterized by a variation of quality and quantity in an outcrops to another. As such, the economic importance gypsum deposit is observed in the Triassic of Guellal.
Contrary to gypsum, rock salt (halite) is prevalent only in the depth of the Triassic
outcrop in Guellal, and is forming a deposit of a great economic importance.

Index. décimale : 640 Industrie Alimentaire Résumé : Olive oil is one of the oldest vegetable oils and the only one that can be consumed in its raw form without prior treatment. The well-known health benefits of olive oil are linked to its fatty acid composition in which oleic acid is the main component, and the presence of minor biomolecules, such as vitamins and natural antioxidants.
The strong demand for quality virgin olive oil is not only due to its health virtues, but also to its organoleptic properties.
In Algeria, plantations are characterized by great diversity and for the most part, by a traditional olive orchard. The consumption of oil maâsras is today a basic diet in many rural areas of the country. In these regions, oils are considered to be of good quality. The present study on olive oil produced in several olive growing regions of Algeria has the dual purpose of studying the chemical parameters and fatty acid composition by conventional analytical methods, and of characterizing these oils by spectral methods, including 3D- fluorescence spectroscopy.
Different chemometric methods: Principal Component Analysis (PCA), Canonical Discriminant Analysis (CDA), Independent Component Analysis (ICA), and PARAFAC (PARAllel FACtor analysis) are used to treat the data.
The first results indicate that the chemical composition of olive oils from different regions of Algeria is quite variable.
The Principal Component Analysis (PCA) was used for an initial exploratory analysis of the data. The first three latent variables explain 64.1% of the total variance of the samples from the five regions. Then, a Canonical Discriminant Analysis (CDA) showed that the most discriminant variables are K270 and Delta K for oil samples from the region of Constantine, the peroxide and γ-tocopherol for samples from the regions of Tizi Ouzou and Sétif, respectively.
The variations due to the presence of Rayleigh and Raman scattering in excitation– emission fluorescence matrices, distort the PARAFAC model.
A solution to eliminate the artefacts interfering with the relevant information was achieved by applying Independent Component Analysis to the row-wise unfolded array. A PARAFAC model was then built on the refolded array, reconstructed without the independent component(s) related to the “artefact signals”. The PARAFAC components obtained were interpreted by relating them to some compounds present in the analysed samples. The results of multivariate analyses show that the chemical parameters of olive oils contain enough information to distinguish the production areas of studied Algerian oil.Diplôme : Doctorat en sciences En ligne : ../theses/agronomie/BEN5330.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=4438 Caractérisation de l'huile d'olive algérienne : apport des méthodes chimiothérapiques [texte imprimé] / Hamida Benabid ; Université Mentouri, Editeur scientifique ; H.

Index. décimale : 622 Electro-Technique Résumé : Non Destructive Testing plays an essential role in safety, quality and the reliability of industrial systems. In this thesis, two eddy current sensors designed form several coils that are placed in array form to characterize fiber orientation and for detecting in-plane fiber waviness in unidirectional CFRP.
The principles of the proposed sensors are based on those of conventional rotating sensors. Our proposals allow the elimination of mechanical rotation, which offers advantages of speed of inspection, precision and miniaturization. The first sensor is based on the absolute mode; however the second uses the transmission-reception mode. To benefit at the same time from the advantages of the interactive arrayed sensor and the receiving arrayed sensor, we have proposed a synthesis of these two sensors in a single device. This gives a possibility to use a single sensor that functions both as an interactive arrayed sensor and as a receiving arrayed sensor. We are used the 3D finite elements method in 'Comsol multiphysics' environment to study the electromagnetic phenomena. To validate the
results obtained by simulation, experimental measurements were carried-out in the case of two coils sensor.

BiologieTags : Algérie vesce diversité caractérisation écogéographie marqueurs génétiques Algeria vetch characterization diversity ecogeography genetic markers ??????? ?????? ???? ??? ????????? ??????? ?????? ?????? Index. décimale : 570 Sciences de la vie. Biologie Résumé : The Convention on Biological Diversity affirms the sovereign right of states to derive
equitable benefits from the use of plant genetic resources present on their territories. This right
is, however, linked to the national responsibility to conserve these resources and promote their
use. Gaps and needs in conservation activities and in the promotion of such resources exist. The
considerable benefits that could be achieved through these resources are neither achieved nor
equitably shared.
The vetch (Vicia L.) is a forage legume well positioned to help meet the growing demand
for feed crops and provide diversity for farming systems. It is important to ensure that its genetic
resources are conserved and therefore available for continuous selection of the interesting taxa.
This study is the first of its kind in the evaluation of 11 natural vetch taxa collected in
Algeria, through the use of genetic markers represented by 78 morphological characteristics of
the plant, 3 fractions of storage proteins, 3 enzyme systems, 12 physical properties of the grain
and a DNA marker represented by 4 ISSR primers. In parallel, 5 ecogeographic parameters
were used for the characterization of accessions collection sites.
The discrimination of the Vicia sativa complex taxa via morphological and ecogeographical descriptors is difficult because of the existence of a continuous variation. For the
other taxa, morphological analysis reveals more stable groups which are consistent with the
taxonomy of the genus. Knowing the limits of species distribution areas along the ecological
gradient is crucial as a source of information on the evolutionary potential of evaluation
programs and conservation of biodiversity. The data collected could be promoted in
programming future collecting missions. The storage proteins electrophoregrams can be used
as passport data for the genetic identity of vetch accessions. Zymograms are compatible with
traditional taxonomic boundaries of species. The discriminant analysis by the physical
properties of the grain showed no correspondence with the systematic. The four ISSR primers
used revealed 100% polymorphic bands. However, their utility in other studies of variability is
to be discussed. Difficulties in identifying taxa put light on the need for taxonomic revision of
the flora of Algeria.Diplôme : Doctorat en sciences En ligne : ../theses/biologie/BEC7092.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10512 Le genre Vicia L. en Algérie caractérisation de 11 taxa naturels : Approches éco-géographique, morphologique, biochimique et moléculaire [texte imprimé] / Sakina Bechkri, Auteur ; Douadi Khelifi, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2017 . - 201 f. ; 30 cm.

phenotypical diversity that exists within a collection of symbiots isolated from nodosities of
three Fenugreek populations originated form different regions of east Algeria.
The SDS page has revealed a great level of proteic polymorphism between the isolates. This
technique has allowed us to highlight the possible multiple infection among Trigonella L.
All the strains are infective towards Trigonella L with a relative efficiency that is
reflected by a good growing level of the obtained feet.
The fast growth of the strains and the assimilation of the charred substratum have
revealed profiles that are comparable to those of Rhizobium. In contrast, the strains have
manifested, like the Gammaproteobacteria, a great resistance to heavy metals and antibiotics.
A great tolerance to NaCl, pH, and temperature variation has been noticed for the whole
collection.
We have defined, on the base of the Azote fixative potential and the tolerance of
alkalinity, candidates that are efficient enough to be used for inoculation in the field.Diplôme : Magistère En ligne : ../theses/biologie/CHA5602.pdf Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=1817 Caractérisation des bactéries isolées à partir du genre Trigonella L.
