Petrographic observations and statistical analysis of petrophysical data of forty-five subsurface Cretaceous sandstone samples reflect good reservoir characteristics in some intervals due to high porosity (varies up to more than 27%) and permeability (varies up to more than 826 mD). In other intervals, they reflect fair to bad reservoir characteristics due to low porosity (reaches a value of 6.25%) and permeability (reaches a value of 0.01 mD), caused by matrix and diagenesis processes. FZI (flow zone indicator) and R35 (pore aperture corresponding to the mercury saturation of 35% pore volume) were calculated from the measured porosity and permeability, by defining FZI and R35, four hydraulic flow units (HFU1, HFU2, HFU3 and HFU4) in a reservoir have been identified. HFU1 is distinguished by FZI values that lie between 3.71and 8.11 lm, meanwhile, the values of R35 are greater than 10 lm. HFU2 is marked where the FZI values are between 1.32 and 3.70 lm, while the values of R35 are between 2 and 10 lm. HFU3 is noticed where FZI shows values between 0.40 and 1.31 lm, while the values of R35 are between 0.5 and 2 lm. The HFU4 is evaluated where FZI values are between 0.06 and 0.39 lm, and the R35 values are less than 0.5 lm.

Pour cette raison, quinze visites ont été effectuées dans trois sites d’abattage. Dans chaque visite, onze échantillons de dix grammes de peau du cou ont été prélevés par tuerie après chaque opération. Les échantillons ont été soumis au dénombrement de la flore mésophile aérobie totale (FMAT), des coliformes totaux (CT), des entérobactéries et des staphylocoques. Les résultats de ce travail montrent que les conditions d’hygiène à l’abattoir conditionnent fortement la qualité du produit fini. Ainsi, l’échaudage, la plumaison et l’éviscération constituent des points critiques de contaminations croisées des carcasses.

A total of 96 samples of chicken meat were collected from retail outlets (popular market, artisanal slaughterhouses, poulterers' shops and supermarket) in Meknes (Morocco). The level of micro- organisms on chicken carcasses was assessed using t he excised breast-skin technique. Levels of mesophiles , coliforms, Escherichia coli and Staphylococcus aureus on carcasses from popular market and artisanal slaughterhouses were significantly higher (P < 0.05) than in poulterers'shops and supermarket . On the basis of the CNERNA "Centre Nationale d'Etudes et de Recommendations sur la Nutrition et l'Alimentation'' Standards, 24 % of the samples from popular market and 16 % from artisanal slaughterhouse were also regard ed as being of unacceptable quality. The main reason f or the lack of acceptability was excessive counts of mesophiles and coliforms. Three classes of retail o utlets have also been put into evidence differing from eac h other in terms of hygienic conditions in the slaugh tering and sale of poultry meat.

The time management strategy, developed in this work, consists of applying two modes of alternating teaching, the classical mode "work and make work" and the "actual - virtual" presence of the teacher mode using the software Netsupport School. The aim of this paper is to study the impact of the application of this software solution in two heterogeneous lessons of the French language, specifically of oral activity, for a subgroup of a double-level class (2nd Primary Year + 3rd Primary Year). The obtained results are conclusive since this approach has made it possible to reduce dead time and the teacher's great effort and to involve strongly the learners in the construction of the concepts

The class was divided into two homogeneous groups. A group, taken as a comparison group, followed a traditional session while in the other group we applied the developmental instructional sequence. First results, obtained from direct observation during the implementation and for evaluation, have shown that serious games have a positive impact on learning.

L'évaluation des enseignements prodigués dans cette formation est une nécessité pour faire évoluer sa qualité et suivre son impact sur les compétences des futurs enseignants. Dans ce papier, nous présentons les résultats d'une étude menée par l'équipe pédagogique de la didactique des sciences au ex-CRMEF-Sous Massa – Draa antenne Ouarzazate, concernant la formation des professeurs stagiaires dans les modules planification et mise en œuvre des apprentissages en éveil scientifique au cycle primaire bilingue. L'étude est réalisée par le biais d'une enquête auprès des professeurs stagiaires (promotion 2014-2015), afin de recueillir leurs appréciations à propos des différents volets de la formation prodiguée au cours de cette année (contenu, temps dédié à chaque élément, efficacité des actions et développement des compétences) et compris ...

This study evaluated 35 morphological characteristic parameters and the number, shape, and spatial location of bones in the skull and vertebrae of the mandarin fish Siniperca chuatsi and big-eye mandarin fish Siniperca kneri. We can understand their ecological adaptability, compare their morphological and skeletal differences, and elucidate the relationship between their phenotypic trait differences and skeletal characteristics. The results were as follows: 1. The Student's t-test results revealed significant differences between S. chuatsi and S. kneri in terms of head depth, head back length, snout length, interorbital distance, distance of the eyes from the oral fissure, and width between the posterior trunk and base of the caudal fin. Principal component and discriminant analysis showed that the main morphological differences between S. chuatsi and S. kneri were in the eye position, head hump and body shape. 2. There was no significant difference in the number and shape of the skull and vertebrae between S. chuatsi and S. kneri, but they differed in spatial position. The terminus of the maxilla in S. chuatsi is located at the lower border of the postorbital bone, but at the anterior in S. kneri. The size of head hump is closely related to the spatial location of the splanchnocranium in S. chuatsi and S. kneri. The angles between the caudal vertebrae centrum and each of the following: the neural arch and spine; haemal arch and spine of S. chuatsi are larger than those of S. kneri. In conclusion, the morphological differences between S. chuatsi and S. kneri are closely related to the spatial position of skeleton. These phenotypic differences reflect the ecological adaptation of mandarin fish to different natural environments.

En profitant de l’évolution des nouvelles technologies particulièrement le cloud computing qui permet d’améliorer l’accès, le partage et le stockage des informations, nous nous servirons d’une plateforme d’apprentissage en ligne. A notre connaissance aucune tentative de mise en évidence de l’impact de cette nouvelle approche sur la formation des futurs enseignants n’a été faite. Le résultat de cette étude a montré que l’utilisation la classe inversée comme stratégie d’apprentissage améliore l’efficacité et les performances des professeurs stagiaires. Cette stratégie permet de faciliter le développement de la compétence d’auto-apprentissage et permet d’améliorer la motivation les apprenants et combler la différenciation des outils d’apprentissage.

It also aims to identify the challenges related to this integration. Data collection was carried out through a review of messages shared by members of this group between October 2017 and September 2018, and through a questionnaire survey of trainees. The results revealed that the messages essentially address pedagogical, didactic, and relational themes. The majority of the trainees (84%) reported that the content of the interactions in the WhatsApp group is appropriate to their needs. In addition, most of them are satisfied with the contribution of this virtual community to their professional development and say that it has prepared them for the real demands of teaching practice. The major challenges faced by the trainees when integrating this tool are the low internet connection speed, connec...

A total of 100 door samples were obtained, 20 each from the five faculties within the university's main campus. These were cultured and identified using appropriate protocols. A total of 26(26.0%) isolates were identified as Staphylococcus aureus. Faculties of Administration and Arts jointly accounted for the highest prevalence with 40%. The antibiotics susceptibility test revealed that Gentamicin was the most effective of all the test antibiotics against the Staphylococcus aureus isolated. The multidrug resistant S. aureus isolates 12(46.2%) were observed to have produced beta lactamase enzymes implicated in beta lactam antibiotics resistance. Observation from this study showed that there is a high level of antibiotics abuse or misuse with resultant multidrug-resistant S. aureus isolates in the study area.
