The aim of this work was to characterize lactic strains isolated from donkey milk byidentifying them and testing their growth potential (at different salt concentrations anddifferent temperatures) and their ability to withstand in vitro simulated digestive hostilities asa criterion for eligibility for "probiotic" status. The results obtained showed that the nine lacticstrains isolated from the donkey milk used in this work keep growing at 10, 45 or 63.5 °C andin the presence of 2.4 and 6.5% (w / v) NaCl. They also display a differential resistancecapacity depending on the strain type under the conditions of the digestive tract simulated bysalivary α-amylase, acidity and gastric secretion, bile salts, lysozyme and pancreatic enzymes(pancreatin, lipase, amylase and proteases). Thus, the strains are initially sensitive to salivaryα-amylase but recover growth again after the first 30 minutes of exposure. All strains areslowed in their growth by simulated gastric acidity at levels between 25 and more than 40%.There were 2 strains (S1 and S2) out of 9 tested whose bile salt and lysozyme survival wassignificantly (p <0.05) reduced by 35%. Exposure of lactic acid strains for 5 hours topancreatic enzymes did not significantly alter their survival, the lowest (around 80%) wasrecorded for strains S1, S3 and S7 whereas other strains kept growing giving rise to more than100% of survival. It is the S8 strain that has the most resistance to proteases. S5 and S8 strainswere the most resistant strains to the digestive tract conditions, and therefore were selected formolecular identification by MALDI TOF, which revealed that they belong to the genusEnterococcus. Analysis of the MALDI TOF mass spectra have shown that the two strains (S5and S8) belong to the same species which is the species faecium with scores of 2.40 for S5and 2.36 for S8.

This study was conducted to assess the effectiveness of institutional linkages between agricultural research stations and the agricultural extension centers. A questionnaire was distributed among nineteen researchers and twenty-two Extensionists. The Extensionists comprised eight Federal Extensionists and fourteen State Extensionists. The study showed that: All researchers interviewed are MSc and PhD holders while only few Extensionists had MSc degree. Researchers had little involvement in various extension tasks and Extensionists had little involvement in various research tasks The majority of researchers described research-extension relationship as medium while all Federal Extensionists described research-extension relationship as non-existing and the majority of State Extensionists describe research –extension linkage as medium. Extensionists depend much on the Ministry of Agriculture in directing their work while researchers depend much on the Federal Ministry of Science and Technology in directing their work. The majority of researchers didn’t depend on suggestions from extension in directing their work. The major conclusion reached in this study is that the institutional linkages between research and extension were weak and the relation-ship between them depend on informal relation ship between researchers and Extensionists. It is therefore highly recommended that: Extensionists should have more funds for education opportunities. Permanent availability of extension worker at research station. Formalizing the relationship between research and extension through establishment of formal research-extension channels. Revise the managerial hierarchy of all parties concerned with a view of enhancing cooperation between them. Mutual respect and understanding to the role of each other through sensitivity training.

L'infection maternelle périnatale est l'une des grands défis de la santé publique mondiale. L'infection bactérienne du nouveau-né est l'une des causes de décès néonatales dans le monde, elle est responsable de 12% de décès périnatales. Le nouveau-né est principalement contaminé au cours de la grossesse, ou en per partum. La présence de certains facteurs de risque maternels et f'tales favorisant cette colonisation. Les principaux agents bactériens responsables de ces infections néonatales sont le Streptocoque de groupe B, l'Escherichia coli. A la naissance, il n'existe pas de signes spécifiques de l'infection bactérienne néonatales, cependant la présence d'une détresse respiratoire, neurologique, et des troubles hémodynamiques, mènent vers une enquête étiologique. Le diagnostic repose sur un faisceau d'arguments cliniques, biologiques, et des prélèvements bactériologiques. Le traitement de ces infections néonatales est une urgence à cause de la gravité et des conséquences néonatales, et d'o{scriptl}u l'intérêt d'un diagnostic et d'une prise en charge précoce. Toutefois, la prévention, la vaccination, le dépistage précoce sont indispensables dans la prise en charge des infections néonatales.

En dépit de l'importance accordée à l'oral qui constitue actuellement le centre d'intérêt des perspectives didactiques de FLE, la compétence scripturale prône elle aussi une place de choix et une exigence que chaque apprenant doit maîtriser.L'objectif de cette étude scientifique est de démontrer l'efficience d'intégrer les ateliers d'écriture en classe de FLE et son effet dans l'amélioration de la compétence scripturale chez les apprenants de cette langue. Afin d'atteindre notre objectif, nous avons adopté l'expérimentation comme outil d'investigation, qui a été menée auprès des étudiants de 1re année licence de l'université Hamma Lakhdar, El-Oued.

Dans le contexte global de la diversification de l’utilisation des ressources naturelles,le recours aux énergies renouvelables et en particulier le solaire photovoltaïque se faitde plus en plus fort .Dans notre travail, nous avons calculé les propriétés structurelles et électroniques du AlGaP2au moyen de la méthode des ondes planes linéaires (FP-LAPW), qui est basée sur la théoriede la densité des fonctions (DFT). Pour le calcul des propriétés structurelles (constante deréseau et paramètre de compressibilité). La valeur de la constante de réseau obtenue àl'équilibre est cohérente avec les résultats expérimentaux disponibles.Pour calculer les propriétés électroniques (bandes d'énergie et densité d'état), nous avonsutilisé une approximation de gradient GGA généralisée. Densité du site LDA etapproximation mBJ. Lors de l'utilisation de l'approximation mBJ, nous avons constaté qu'il yavait une amélioration significative des résultats par rapport à l'approximation GGA, LDA etKDA par rapport aux résultats expérimentaux

This study aims at investigating the role of collocation in enhancing Sudanese undergraduate students’ reading comprehension. The general assumption is that English Language learners at university level need to improve their reading comprehension by enriching their vocabulary knowledge. This study aims to demonstrate that language use requires collocation knowledge, identifying the main causes behind the difficulties which students encounter in theirreading comprehensionsuggesting some devices that enrich vocabulary knowledge. Thestudy employed threetools to collect data; teachers’ questionnaire, students’ tests(pre and posttest) and a course of collocation. This accomplished through several steps: 1- Choosing 24 students at the English department, College of Education, at Sudan University of Science and Technology as subjects. 2- 50 instructors of English, who are all holders of different collegedegrees in English language, answered the teachers’ questionnaire. They all teach in different English departments at different Sudanese universities. The data collected via the questionnaire and the two tests were subjected to statistical analysis using the SPSS package program. The main findings show that Sudanese Undergraduate Students (SUS) find difficulties in understanding the use of collocation. They concentrate their language learning on grammar rather than other aspects of language learning. Most of the English Department (ED)at the Sudanese Colleges(SC) donot include collocation teaching in their syllabi.The study concluded that collocation knowledge brought about statistically significant change in the performance of the students in the posttest which means that the students got benefit from the collocation course applied from the middle of September to the first week of December), so, comprehending language in chunks(collocation) leads to enhancing and comprehending reading. The study recommended the implementation of teaching collocation for Sudanese students majoring English at their syllabi. It also recommended intensive and extensive reading from their first year at university.The study gives some suggestions on other further studies ininvestigating the role of collocation on enhancing writing, listening or communication. It also point out that more findings may be anticipated by exploring more other instruments e.g interview or group discussion.

The research is designed to investigate the impact of the relationship between self-hyper femininity acceptance and objectification perception among female television presenters during primetime in Lebanon along with identifying the perception of viewers towards these (primetime) female presenters. The research will help in identifying if there is a significant relationship between the two variables; (i) self-hyper femininity and self-objectification; Lebanese primetime TV presenters and the objectified perception of audience. This study started with a literature review that is based on the self- hyper femininity acceptance and objectification perceptions, gender roles and sex theory, male gaze, castration and Laura Malvey study, feminism and feminist theory, objectification theory, sexual objectification and its acceptance, and the aftermath of sexual objectification. Unfortunately, in all parts of the cultures the visual media ensures that women are noticed for their physical appearance and sexuality not for their intellectual and intelligence. The methodology part aims to identify how female presenters of primetime programs onLebanese TV shows perceive themselves, and second how viewers of these Lebanese shows perceive these female presenters. So qualitative and quantitative research designs are utilized. The quantitative research approach assesses relationships between variables and study the perception, attitudes, or behaviors of a large population. Analysis thus in a quantitative research design is based on the number of respondents, frequencies, and their equations. Consequently, results obtained from a quantitative research are objective since they are based on numbers. This quantitative research is based on random sampling that was applied because respondents were selected randomly, anyone who watches TV is a potential respondents. The questionnaire was uploaded through a link using Google forms and accordingly distributed over a sample of 400 respondents. On the other hand, a qualitative approach is used to collect detailed and rich information of a small population based on in depth interviews. The population under this study includes all female TV presenters on Lebanese TV channels that present programs during prime time. The population is not very big in comparison to other population. In fact, six private TV stations operate in Lebanon. They include MTV, LBC, Aljadeed, NBN, OTV, and Future TV. The population is 10 presenters, and the sample under study is only six of them who are: Ghada Eid, Carla Haddad, Anabella Hilal, Carmen Saleme, Zeina Janbieh, Sawsan Safa. The findings of the research identified how female presenters of primetime programs on Lebanese TV shows perceive themselves and how are these TV female presenters perceived by the audience. According to the results obtained, the audience of prime time on TV believe that female TV presenters in Lebanon are beautiful and attractive, males are more likely to think that these presenters are strong and powerful and have authority and impact over the society. Respondents also believe that female TV presenters in Lebanon are known for their physical and sex appeal. In comparison to the self perception of the TV presenters, they considered themselves as attractive and beautiful. Majority of them consider that beauty and attraction is very important to become successful in presenting any program. For majority of presenters the look and appearance is very essential to hook up and attract the audience but the content of the program is what keeps them watching. That is why, majority of TV presenters perceive themselves as highly feminine and not hyper feminine because they consider that the appearance and the program content complement each other. As a conclusion, results indicated that Lebanese viewers do perceive females TV presenters of prime time shows as hyper feminine and consider that hyper femininity contribute in the success of the TV presenter due to the fact that 3 out of the top 4 according to the viewers’ perceptions are hyper feminine. Yet since the second most successful presenter was not perceived as hyper feminine, other factors like the content and the material being delivered influence the success of these presenters. Interviews with the TV presenters confirmed the results of the questionnaire, the interviewees indicate the importance of the look and the appearance but they also emphasized on the content of the program.
