Résumé :	The Al-Mg alloys are widely used in industry especially for marine applications since they possess good properties such as general corrosion resistance, strength, weldability, weight compared to other Al alloys and formability. These properties are related to the magnesium content and to the applied heat treatments. These alloys undergo phase transitions by precipitation which improves their mechanical properties following solution heat treatments and suitable ageing ones. Although these alloys are already well studied, the questions concerning the stability of the microstructure and the effect of the various heat treatments are always asked. In this work, we present a study on the evolution of the precipitation (continuous one) reactions after quenching, more precisely the evolution of the precipitated phases (formation, coalescence, and dissolution), in Al-(12, 10 and 8)wt.% Mg alloys aged at 150 and 250 °C during different ageing times. The use of various experimental techniques as differential dilatometry, differential scanning calorimetry, scanning and transmission electron microscopy, X-ray diffraction, microhardness and internal friction measurements, shows their importance and their complementarity in the study of ageing process in these alloys. The obtained results clarified the parameters that govern the stage of β’and β particles appearance and the mechanical responses to the applied heat treatments. The ageing effect of a supersaturated solid solution on the Temperature Dependent Internal Friction (TDIF) spectra has been studied. A detailed TDIF analysis revealed the sensibility of the internal friction technique to the formation of semi-coherent and non-coherent phases (β' and β) but not enough to the formation of coherent phases (GP zones). Several observations on the nature and the shape of the precipitates are also discussed.

Résumé :	The present work consisted on a phytochemical and biological study of the species Pituranthos battandieri Maire, Algerian variety from the Apiaceae family, endemic to the Algerian and Moroccan Sahara. To the best of our knowledge this species has never been studied before. This reason and the endemism of this rare species encouraged us to undertake this work in which we also reported the chemical composition of the essential oil of its aerial parts performed by GC and GC/MS analyses. Our experimentation allowed the separation and purification of 23 compounds through the use of various chromatographic techniques (CCM, CC). All these structures have been elucidated by the combination of spectroscopic methods mainly: (UV-Vis), 1D NMR (1H, 13C, DEPT), and 2D NMR (COSY, HSQC, HMBC, NOESY), We also used high resolution mass spectrometry methods (HR-EI-MS and HR-ESI-MS) and comparison with literature data. Among the isolated compounds, 13 coumarins from which 5 were new, 4 flavonoids, 2 steroids, 3 phenolic compounds and 1 reduced sugar. In addition, a biological valorization consisting in the evaluation of the antioxidant activity was carried out on the n-BuOH extract of the aerial parts of Pituranthos battandieri Maire. This study showed that this species has a biological efficiency. In this study we also carried out an antibacterial assay against some pathogenic organisms, the microbiological results showed that this butanolic extract did not show antibacterial activity. The GC-FID and GC/MS analyses of the essential oil of Pituranthos battandieri Maire showed that this oil is mainly composed of myrcene (8.9%), α- phellandrene (17.5%), α-terpinene (14%), o-cymene (11.6%), β-phellandrene (3.5%), cis-linalol oxide (furanide) (5.9%) and trans-β-caryophyllene (3.4%).

Résumé :	In this thesis, we are studying a class of continuous-time bilinear processes (COBL(1,1)) generated by some stochastic differential equations where we have investigate some probabilistic properties and statistical inference. We use Itô approach for studying the L2 structure of the COBL(1,1) process and its powers for any order with time varying coefficients. Furthermore we prove that these results can be obtained by using the transfer functions approach, moreover, by the spectral representation of the process, we give also conditions for the stability of moments, in particular the moments of the quadratic process provide us to checking the presence of the so called Taylor property for COBL(1,1) process. In a second part of this thesis, we use the results of the first part and we propose some methods of estimation for involving unknown parameters, so, we starting by the moments method (MM) to estimate the parameters by two methods, taking into consideration the relation that exists between the moments of the process and its quadratic version and those associate with the incremented processes where we have showed that the resulting estimators are strongly consistent and asymptotically normal under certain conditions. Using the linear representation of COBL(1,1) process, we are able to propose three other methods, one is in frequency domain and the rest are in time domain and we prove the asymptotic properties of the proposed estimators. Simulation studies are presented in order to illustrate the performances of the different estimators, furthermore, this methods are used to model some real data such as the exchanges rate of the Algerian Dinar against the US-dollar and against the single European currency and the electricity consumption sampled each 15mn in Algeria.

The modeling and simulation of the PV and wind systems were presented with an MPPT command to maximize the power delivered.

Résumé :	The Stone pine (Pinus pinea L.) is a forest tree species to be valorized on the economic level by its production of wood and pine nuts. In Algeria, it occupies a total surface of 3506 ha; the largest surface is located on the massif of Djebel Ouahch 2278 ha. The present work aimed mainly at determining on the development and adaptation of this forest species in the zone of Djebel Ouahch for possible reforestations in form of equilateral plantings with a medium age of 40 years. Medium fruit-bearing production is assessed between 3,80 and 523,76 tons of pine nuts in shells. In good conditions, the quantity of harvested is 554,110 cone / hectare in the studied zone. The physicochemical characterization of the study zone reveals a balanced texture, with a low percentage in loam (~ 27 %), a medium pH ranged between 6 - 7.5 and a very low total quantity of limestone. On morphological level, the germinal capacity of seeds is of good quality with a bellow and above-ground live biomass fairly sustained. These morphological parameters showed a statistically significant difference among different treatments and seasons. The seedlings grown in semi controlled conditions suffer from short –term stresses (03 hrs) in a range of temperature varying between-10 °C and 50°C while the biochemical markers (chlorophyll, proline, soluble sugars, proteins and enzymes) are quantified. Under a thermal pressure, the results show an increase of the chlorophyll pigments at 38°C. The seedlings show an adaptation to lower temperatures at 44°C for the proline, the soluble sugars, the catalase and MDA. The intensity of hydric and thermal stress is significant for all analyzed parameters. The Pine Seedlings are capable to accumulate the different osmolytes in the different organs in response to combined stress. The accumulation of soluble sugars is highly marked for the control at 38°C; while the increase of the proline is very significant in roots under thermal pressure at 38°C at level N1 and at 44°C at level N2 (55 %). The Seedlings show clear features of biochemical adaptation in response to combined, hydric and thermal, fluctuations. The phenology analysis was observed on branches of a growth ranging between 15-20 years in the region of Provence-Alpes-Côte d'Azur and in the region of Djebel Ouahch. The exclusion of rainfall diminished the annual number of growth cycles of shoots and their duration and also the speed of needles growth. The quality of the populations of Stone pine is moderately stable with a weak rate of regeneration and a quite high mortality rate due to anthropic action and fires.

Résumé :	The main objective of this investigation is to study the response of different potato explants Spunta and Kondor to callogenesis and somatic embryogenesis in the presence of combinations with NAA / BAP and 2,4-D / BAP. We opted from the start for the buds and internodes as explants. The color and texture of the calli vary according to the nature of the growth regulators and the presence or absence of light. With the NAA / BAP combination the Spunta variety develops the best callogenesis in all environments compared to the Kondor variety depending on the concentration of hormones, there is a range of variations of days required for callus initiation, the percentage of explants that have developed calluses, texture, color and degree of its formation. For the combination 2,4-D / BAP the results indicate that after three weeks of culture, the calli are moist, soft and friable in green and whitish-green and white with the NAA / BAP combination, and green, light green and brown color for both explant with all media with of 2,4-D / BAP combination. Callus growth varies according to culture conditions like light and temperature, callus incubated in the dark give brown colors and a friable to compact structure, while the calluses incubated in light show varying colors (green, light green, white and brown) that are due to the action of light on the photosynthetic pigments. The rate of callogenesis and fresh weight of calli are positively correlated with the concentration of auxin. The histological study of callus obtained from internodal explants after 3 and 60 days shows that cell division is produced in the epidermis only after three days of culture and then spread to the first layer of the cortex. During somatic embryogenesis the calluses of different explants develop with all media (1-2) buds and dense roots. Exceeding three months of incubation the calli are larger and begin to brown and lose the green color after degradation of chlorophyll.

Résumé :	The main objective of this investigation is to study the response of different potato explants Spunta and Kondor to callogenesis and somatic embryogenesis in the presence of combinations with NAA / BAP and 2,4-D / BAP. We opted from the start for the buds and internodes as explants. The color and texture of the calli vary according to the nature of the growth regulators and the presence or absence of light. With the NAA / BAP combination the Spunta variety develops the best callogenesis in all environments compared to the Kondor variety depending on the concentration of hormones, there is a range of variations of days required for callus initiation, the percentage of explants that have developed calluses, texture, color and degree of its formation. For the combination 2,4-D / BAP the results indicate that after three weeks of culture, the calli are moist, soft and friable in green and whitish-green and white with the NAA / BAP combination, and green, light green and brown color for both explant with all media with of 2,4-D / BAP combination. Callus growth varies according to culture conditions like light and temperature, callus incubated in the dark give brown colors and a friable to compact structure, while the calluses incubated in light show varying colors (green, light green, white and brown) that are due to the action of light on the photosynthetic pigments. The rate of callogenesis and fresh weight of calli are positively correlated with the concentration of auxin. The histological study of callus obtained from internodal explants after 3 and 60 days shows that cell division is produced in the epidermis only after three days of culture and then spread to the first layer of the cortex. During somatic embryogenesis the calluses of different explants develop with all media (1-2) buds and dense roots. Exceeding three months of incubation the calli are larger and begin to brown and lose the green color after degradation of chlorophyll. A surprising observation in our study which is the formation of microtubers from the callus of tubercle germs on M1 and M2 medium after 37 to 60 days of incubation. This research has made it possible to highlight the conditions necessary for callogenesis and somatic embryogenesis. In the end it is recommended to try to induce somatic embryogenesis by applying stress (osmotic, with ions, ABA ...), with the addition of organic and mineral nitrogen source for a period exceeding three months.

Résumé :	The genetic improvement of the agronomic traits related to the performance and adaptation to the environments is conditioned by the presence of a genetic and phenotypic variability of the targeted traits in the plant material subjected to the selection. In this work, three trials were conducted on the collection of 26 durum wheat (Triticum durum Desf.) from various origins. The first trial was realized during the campaign of 2011/2012 on the ITGC site of el khroub station in rainy conditions. This site represents the highest Algerian eastern plains. To assess the extent of phenotypic variability for future use. Various phenological and physiological parameters (The heading stage and maturity date, the temperature of crop canopy, relative water content), agronomics (The number of fertile tillers (NTF), the number of grass tillers (NTG), and (NTF/NTG). And quantitative morphological characteristics (plant height, flag leaf area, the length of beards, the spike length) and qualitative characteristics (spike and beards color and pubescence of glumes) were studied in the genotypes of durum wheat. The results obtained reveal highly significant varietal differences for all measured parameters. The second trial was conducted during the 2012/2013 campaign on the same site of previous experiments; in order to compare the production and performance of varieties studied under different climatic conditions. A significant effect years and varieties were revealed for the set of parameters, our results show that the end-of-cycle thermal stress induces a decrease of thousand kernel weight. Lack of water causes a decrease in the number of heads per m² and the number of grains per ear of all varieties. The Hoggar and Tassili varieties have good production capacity during the two trials compared to the other varieties. Highly positive significant links have been found between grain yield and the number of grains produced per unit area, and the number of grain per spike. The principal component analysis, described a total variation of 77.36 %, and the hierarchical classification has divided the genotypes according to their phenotypic variation into three distinct groups. The first one includes old varieties showing adaptability to climatic conditions to the studied area. They are late and large. In opposition to the two groups formed by varieties from (CIMMYT, ICARDA, and Italy) . They are characterized by a small, early maturity at heading, and show higher values for all performance components. The third trial was conducted in this study to evaluate the genetic diversity of durum wheat varieties using two types of molecular markers (SSR and RAPD). In total, 44 and 30 alleles were generated by 10 SSR primers and 05 RAPD primers respectively. The results obtained by the use of microsatellites, highlights variability within the 26 varieties. Reveal significant allelic diversity characterized by high polymorphic information content (PIC) values, highest are obtained by primers WMC 307 and BARC 142 with (0.85 and 0.73) respectively. And in agreement with the large number of polymorphic alleles detected in varieties with an average of 11.8 alleles.These results reinforces and justify the choice to use these primers association analysis in our durum wheat varieties. The classification of varieties according to UPGMA (Unweighted Pair Group Method with Arithmetic averaging) showed a wide genetic diversity, can be used in the choice of parents in the breeding program. Modern wheat varieties have diverged from Algerian and Italian durum wheat into two main distinct clusters. The results estimated by the RAPD markers also reveal a genetic polymorphism expressed by a PIC (0.31) and Shannon diversity index (0.410). AMOVA (Analysis of Molecular Variance) showed that genetic variation within groups represented 97% (ΦPT = 0.173 p <0.05).

Résumé :	Bilateral adrenalectomy has been shown to damage the hippocampal neurons. Although the effects of long-term adrenalectomy have been studied extensively there are few publications on the effects of short-term adrenalectomy. In the present study we aimed to investigate the effects of short-term bilateral adrenalectomy on the levels of pro-inflammatory cytokines IL-1β, IL-6 and TNF-α; the response of microglia and astrocytes to neuronal cell death animal behavior as well as oxidative stress markers GSH, SOD and MDA over the course of time (4h, 24h, 3days, 1week and 2weeks) in the hippocampus of Wistar rats. Our results showed a transient significant elevation of pro-inflammatory cytokines IL-1β and IL-6 from four hours to three days in the adrenalectomized compared to sham operated rats. After one week, the elevation of both cytokines returns to the sham levels. Surprisingly, TNF-α levels were significantly elevated at four hours only in adrenalectomized compared to sham operated rats. The occurrence of neuronal cell death in the hippocampus following adrenalectomy was confirmed by Fluoro-Jade B staining. Our results showed a time dependent increase in degenerated neurons in the dorsal blade of the dentate gyrus from three days to two weeks after adrenalectomy. Our results revealed an early activation of microglia on day three whereas activation of astroglia in the hippocampus was observed at one week postoperatively. A progression of microglia and astroglia activation all over the dentate gyrus and their appearance for the first time in CA3 of adrenalectomized rats hippocampi compared to sham operated was seen after two weeks of surgery. Quantitative analysis revealed a significant increase in the number of microglia (3, 7 and 14 days) and astrocytes (7 and 14 days) of ADX compared to sham operated rats. Our study revealed no major signs of oxidative stress until two weeks after adrenalectomy when a significant decrease of GSH levels and SOD activity as well as an increase in MDA levels were found in adrenalectomized compared to sham rats. In the current study we used passive avoidance test to evaluate the cognitive functions of the ADX rats, we have found that the removal of the adrenal gland caused a behavioral deficit in the adrenalectomized rats compared to the sham over the time (3, 7 and 14 days). Our study showed an early increase in the pro-inflammatory cytokines followed by neurodegeneration and activation of glial cells as well as oxidative stress. Taking these findings together it could be speculated that the early inflammatory components might contribute to the initiation of the biological cascade responsible for subsequent neuronal death in the current neurodegenerative animal model. These findings suggest that inflammatory mechanisms precede neurodegeneration and glial activation

Résumé :	Recently, many researchers have questioned the outright dismissal of translation from the foreign language classroom and called for reassessing its role. Moreover, some scholars welcomed it as a fifth skill alongside reading, writing, listening, and speaking. This study argues for the rehabilitation of translation in the context of teaching and learning foreign languages. It attempts to reconsider the rejection of translation and also to provide more empirical support to the literature in favour of it. So, it was hypothesised that if translation (Arabic-English-Arabic) helped in promoting learning vocabulary as the other four skills do, it would be considered as a fifth skill. To check the hypothesis, this study used both quantitative and qualitative methods. First, questionnaires were administered to teachers of Translation Practice module and thirdyear Applied Language Studies students at the Department of Letters and English Language, University of Constantine 1 to probe their views regarding the use of translation in general and its usefulness in learning vocabulary -in particular. Second, it incorporated two experiments. The first experiment focused on quantitative analysis to investigate the extent to which translation can help in learning lexical items. The second experiment -a thinking-aloud protocols study- was used to gain an in-depth understanding of how translation may promote the learning of vocabulary. The results of the questionnaires showed that the majority of teachers and students believe that translation deserves to be integrated as a fifth skill acknowledging its role in promoting vocabulary learning. The results of experiment # 1 revealed that translation helped students in learning lexical items, especially after the in-class discussion. The analysis of the experiment # 2 showed that translation may serve the learning of vocabulary in many ways as the other four skills do. To sum up, the findings of this research lent more support to the stated hypothesis.

Thesémiopragmatique approach, marked and enriched by other disciplines of linguistics, actually allows to describe an area filled as technical and aesthetic strategies. From this, the approach proposed in this thesis, supported by a methodological apparatus of the pragmatics of language on the one hand and semiotic models on the other hand, try out a comprehensive vision of the various strategies implemented by the advertising of two distinct contexts: Algerian and French. In this sense, first the work submits a large sample of television commercials as cited in a comparative analytical approach and essentially within three major ""organizations"", namely expository, argumentative and iconic. These are tied to the context of the same broadcast, dependent on sociocultural presuppositions of the audience and often play a decisive role in the design of commercial. Then the vision moves towards the recipient body whose investigation leads to a series of performances sometimes positive and sometimes negative and partially shared or neutral to the omnipresence of advertising on the one hand and the extent of its strategies on the other hand.

Résumé :	This study investigates the degree of matching between teaching and learning styles as strategies to develop the Sudanese students' speaking ability. It draws attention of the teachers, the students and the educationists in Sudan to the importance of speaking as one of the most important language skills. The aim of this study is to come out with constructive recommendations for, the teachers, the students and the educationists in order to improve the processes of teaching and learning speaking. In addition, it aims to specify the mismatch between learning and teaching styles that affect speaking English. The sample of the study is 80 first year students at the College of Education and Arts, English Department, Nyala University, Sudan. The instrument used in this study are the students' speaking interview used as a pilot study and two questionnaires. One questionnaire was administered during formal lectures to students, and one questionnaire was administered to the teachers who teach English at tertiary level. Data was statistically analyzed by ""Statistical Package for Social Sciences Program"". The findings of the study indicate that there is mismatch between teaching and learning styles as strategies affecting the speaking skill. In addition, the study points out that these strategies have more impact on the speaking than any other language skill. It also suggests that the teachers who wish to improve their students' speaking skill have to consider these strategies to be matched with the students' learning styles.

Résumé :	This study investigates the degree of matching between teaching and learning styles as strategies to develop the Sudanese students' speaking ability. It draws attention of the teachers, the students and the educationists in Sudan to the importance of speaking as one of the most important language skills. The aim of this study is to come out with constructive recommendations for, the teachers, the students and the educationists in order to improve the processes of teaching and learning speaking. In addition, it aims to specify the mismatch between learning and teaching styles that affect speaking English. The sample of the study is 80 first year students at the College of Education and Arts, English Department, Nyala University, Sudan. The instrument used in this study are the students' speaking interview used as a pilot study and two questionnaires. One questionnaire was administered during formal lectures to students, and one questionnaire was administered to the teachers who teach English at tertiary level. Data was statistically analyzed by ""Statistical Package for Social Sciences Program"". The findings of the study indicate that there is mismatch between teaching and learning styles as strategies affecting the speaking skill. In addition, the study points out that these strategies have more impact on the speaking than any other language skill. It also suggests that the teachers who wish to improve their students' speaking skill have to consider these strategies to be matched with the students' learning styles.

Résumé :	My study about: “Individuality of Penalty and its Role in Realizing the Criminal Policy” “Comparative Study”, dealt with the important questions of this subject about Islamic criminal policy and modern criminal policy, starting by the conceptual concretization of the principle to its projections following its types, finishing by mentioning its role in realizing the criminal justice. And to insure achievement of objectives of this study, I divided the research to two large parts, where I discussed in the first one about the concept of individuality of penalty and its concretization in the Charia and law, and in the second one, I presented types of individuality of penalty and the role of each one to realize the criminal justice, and I reached the following results: That the individuality of penalty is considered as one of the most important principles on which the good criminal policy is based, and on elements exploring its content, and also, is based on another principle having its weight in the domain of the sanction: “principle of proportionality”, both according to Islamic or legal perception. The realizing of the principle of individuality of penalty and its elements demands existence of conditions and the most of them concerns the judicial system, and they are necessities that can helps it to realize desired criminal justice, and the most important one is the specializing of judge and its rehabilitating in one way, and the necessity of finding other voices helping him. The close connection between the principle of the individuality of penalty and criminal justice makes its importance in increase, and we have approved that the present connection is embodied in a relationship of integration between them, objectively and procedurally and teleology. We deliberately prove the real concretization of the principle of the individuality of penalty and we found that its application refers to Islamic criminal policy and its specific penal systems, this good policy based on fair foundations and searching to realize justice. In addition to this, the difference between criminal schools and their different programs, had a different impact in the report of the principle of the individuality of the penalty, although each one of them has its own vision about idea of justice.My study about three kinds of individuality of penalty: (legislative, judicial and executive), conforms to what is decided in the Islamic Charia and what is done by modern laws, making me appreciate that each kind has its own standards, mecanisms and reference on which it is based, and its effectiveness in realizing criminal justice. Also, adopting theory of summary procedures to speed up procedures to find solutions to conflicts is considered as one of the most important principles of Islamic legislation that the modern laws aim to expand its execution to find solution to criminal justice crisis. The achievement of the individuality of penalty and to insure the criminal justice depended from possibility of consolidating efforts of legislator and judge and executor together and the existence of important exigencies including materials that help each authority, to understand new forms of crimes and specifying criminal sanctions decided and leading to a solution to criminal justice crisis even using non criminal methods “consensual”.

Résumé :	The stockbroker in the stock market is of major importance, As it takes care of the support and advice of the company until the end of the actual entry on the stock market, In particular small and medium-sized companies, Where we can say that the success or failure of the company process to enter the stock market will closely depend on the competence and effectiveness of the stockbroker, So investors use stockbrokers for any sale or purchase action because of their monopoly. Through this thesis we will discuss the organization of financial mediation, By referring to the definition, reasons for existence and importance of the stockbroker in the stock market in addition to the conditions of exercise in this field, Then the obligations and rights of the stockbroker, with details on his financial activity by respecting the legal regulations, For various functions carried out either on the primary or secondary market. And we have dedicated Part II of this study to demonstrate the control imposed on the stockbroker and the consequent disciplinary responsibility for their mistakes, since the securities market is among the sectors most open to free competition, in particular by experts with high efficiency. This is why it is necessary for the Algerian legislature to seek similar legislation, to regulate this market and to protect the savings invested through the committee for the organization and supervision of stock exchange transactions, in french COSOB, Which is considered as an essential element of the State intervention in this market. Taking into account the laws and regulations of the market, we have as brokers types of responsibility, Disciplinary liability arising from the breach of the rules of good conduct, punishable by the market authority, and the civil responsibility which is assumed by the stockbroker towards his customer and which relate to compensation for damages resulting from a breach of legal and contractual obligations, On the other hand in the event of a criminal offense under the laws of the market and other relevant laws will be subject to criminal monitoring and penalties necessary in law in this regard.

Résumé :	Real estate loans are seen as an effective mechanism for alleviating economic crises in general and the housing crisis in particular. The conclusion of such a contract requires the intervention of several parties, like banks and financial institutions that specialize in housing loans, where operations are financed to enable middle income groups to own housing. An individual may seek to acquire the ownership of a prefabricated house or build or purchase a dwelling on the basis of designs, provided the financier receive benefits the borrower is committed to pay with a refund equal to what he has borrowed. This takes place at a gradual stage following a set of financial and administrative techniques, each of which is important in concluding a valid and sound contract. The parties to this contract have obligations in keeping with the law, conventions, customs and banking practices.
