Despite national gains in school enrollment, health, and economic development, adolescent girls in Upper Egypt are facing critical gender gaps in schooling (Isharq Program, 2013). The present research deals with how the Ishraq program, as non- formal education, has succeeded in advocating the education of adolescent girls in Upper Egypt and making their transition into formal schooling. Ishraq is a program running under an international NGO that is designed to address the educational problems in rural areas in Egypt where there are problems with schooling for young girls. Ishraq is a second chance for education that is providing necessary skills, such as literacy and life skills, reproductive health, livelihoods information, civic engagement, and sports. Ishraq provides an integrated skill-building package to be delivered in 24 months through the following categories: (1) literacy, (2) life skills, (3) sports, and (4) financial literacy in one of the five lowest-ranked governorates (Fayoum, Menya, Assiut, Qena, and Souhag), according to Human Development Index. The research gathered the primary data from the interviews and the secondary data or desk research from literature reviews, and data available online. The recent results by Ishraq report revealed that there are more than 3000 adolescent girls returning to school since the start of Ishraq in 2001 till June 2013. Moreover, the program contributed to sharing the information with their parents and neighborhoods encouraged other girls to join the program which also motivated parents to educate their girls. The Ishraq program contributed very positively towards improving literacy skills, health gains, and financial planning. The program is being assessed by the population council as one of reputable research organizations. Whereas the great challenge that is facing the program is scaling up Ishraq to a national level which causes the threats in overcoming community norms that hinder mainstreaming of Ishraq girls into formal schooling.

The objective of this study was to evaluate the reproductive and productive performance of the pure Holstein-Friesian herd (imported dams and locally-born daughters) of the Arab Company for Agricultural Production and Processing under the prevailing management and environment during the period 1984- 1995 at El Bagair area in the northern region of the Gezira. In this study 3308 lactation records of 1367 Holstein-Friesian cows (668 imported and 669 farm-born) collected over the years 1984- 1995 were investigated. The data were classified according to the following criteria:1.Whether the cow was imported or farm-born.2.Year of calving3.Season of calving - Three seasons were identified: dry summer (March-June), wet summer (July - October) and winter (November -February).4.Lactation numberSix reproductive and productive traits were calculated from the data. These include:1.Number of services per conception (NSPC).2.Service Period (SP).3.Calving Interval (C.I)4.Lactation Yield (L. Y)5.Lactation Length(L.L.)6.Dry Period (D.P.)The data were analysed by the method of least squares means. They were subjected to analysis of variance using SPSS version 9 statistical package.The overall mean number of services per conception was 1.92±1.97. This trait was significantly affected by year and season of calving (p<0.01), but not by lactation number or type of cow (imported or farm-born). The overall mean of service period was 155.75±1.89 days, being highly significantly (P<0.001) affected by lactation number and year of calving, but not by season or type of cow. Lactation length showed an overall mean of 254.2±1.34 days. It was highly (P <0.001) affected by parity, year and season of calving, but not by type of cow. The lactation yield showed an overall mean of 2828.42±22.38 liters. Lactation number, year of calving and type of cow significantly affected (P<0.001) this trait. The season of calving did not influence this trait significantly. The overall mean length of the dry period was 208.88±27.02 days. It was not affected by any of the four factors studied (lactation number, type of cow, year or season of calving). The calving interval showed an overall mean length of 432.33±2.23 days. It was significantly affected by lactation number and year of calving (P<0. 0 I). The type of cow and season of calving exerted a weak influence on this trait.

Nous présenterons dans ce travail, 549 cas de ruptures prématurées des membranes (RPM), colligées à la maternité B du CHU MOHAMMED VI de MARRAKECH sur une période de 4 ans (de janvier 2004 à septembre 2007). De ce travail rétrospectif ressort certaines conclusions : La RPM reste l’une des pathologies obstétricales fréquemment rencontrée, sa fréquence est de 2,37% des cas. C’est une affection de la femme jeune soit 78,49% entre 20 et 35 ans, primipare dans 59,38% des cas, appartenant à un niveau socio-économique bas, non suivie dans 60,1% des cas. Sur le plan étiologique, on retrouve les antécédents d’avortements dans 12,20% des cas, d’infections urogénitales dans 11,65% des cas, les antécédents de cerclage dans 0,18% des cas et de diabète dans 0,36% des cas. Nous avons relevé comme facteurs mécaniques les grossesses gémellaires avec une fréquence de 1,27%, la macrosomie soit 5,64%, les présentations irrégulières dans 5,75% des cas. Les facteurs infectieux sont dominés par les infections urinaires soit 5,04% et les infections cervico-vaginales soit 3,64%. Dans l’accouchement des parturientes ayant une RPM, le travail est marqué par une élévation du taux de césarienne soit 17,66% dont les indications sont dominées par les souffrances fœtales avec une fréquence de 24,56% et les dystocies dynamiques soit 47,37%. Les suites de couches maternelles sont marquées par une mortalité nulle, mais une morbidité infectieuse globale de 2%. La mortalité périnatale est observée avec une fréquence globale de 5,39%nettement élevée avant terme soit 17,57% contre une fréquence de 0,98% à terme. La morbidité néonatale est dominée par la prématurité soit 23,19% et l’INN soit 4,75%. La conduite obstétricale, face à la RPM est encore très discutée et sans protocole fixe. Nous terminons ce travail en insistant fortement sur la nécessité d’accroître les services de consultation prénatale en vue de dépister et traiter, voire prévenir toutes les causes de RPM. Une hygiène génitale et de grossesse avec une éducation de la femme devrait diminuer l’incidence de cette pathologie de la grossesse.

Les dernières statistiques annoncées par les responsables du ministère de l’éducationnationale concernant le taux d’acquisition des connaissances des différentes matières ontmontré que les élèves ont trouvé beaucoup de difficultés concernant l’apprentissage desmathématiques et le français. Ceci est dû à plusieurs raisons d’ordre pédagogique (méthoded’enseignement ou présentation des concepts) et technique (formation des enseignants).Durant ces dernières années et avec le développement des technologies del’information et de la communication (TIC), les élèves utilisent bien les tablettes ou lestéléphones mobiles pour jouer ou communiquer avec leurs homologues via les réseauxsociaux tels que Facebook. Nous voulons via ce projet de fin d’étude concevoir un systèmeassistant les élèves à apprendre les concepts mathématiques en se bénéficiant des avantagesdes TIC.Le but de ce projet est de proposer une méthode qui facilite le processusd’apprentissage des élèves en prenant en compte toutes les étapes suivies dans le cadre del’enseignement en présentiel. Pour ce faire, nous avons proposé une approche éducativeappelée LISP(P) (Learn, Imaginate, Select, Practice, Play) qui permet de suivre à distance etsans la présence d’un enseignant les phases d’enseignement vues aux cours en présentiel etdevant un enseignant réel.Cette approche a été intégrée dans un système qui s’appelle M2M. Ce dernier estdestiné aux élèves de la deuxième année du cycle moyen et offre la majorité des servicesofferts par les systèmes d’apprentissage en ligne. Ce système offre une interface plus simpleet attrayant les élève à apprendre les mathématiques de manière amusante et sans ennui. Afind’évaluer la progression de l’élève de notre point de vue, le système lui permet de consulterdes tests collaboratifs et individuels pour obtenir le niveau final. L’évaluation s’effectue à lafin du processus d’apprentissage

This research developed a new hydraulic fracturing fluid system that optimizes the non-freshwater Fracturing fluid rheology utilizing chelating agents. A minimal set of additives, including polymer, crosslinker, and chelating agents, were employed in this study. The reason for using crosslinkers is to raise the viscosity and elasticity while the cheating agents are employed to mitigate the impact of saline water. The research initially involved testing polymer compatibility with seawater under standard and harsh conditions. Subsequently, chelating agents were introduced into the system. The addition of crosslinkers posed compatibility challenges due to the high salinity and pH of chelating agents, prompting an in-depth investigation into individual ions in the selected seawater. The effect of each ion on the system was reported, and the conclusions were used to develop a better system. A complex study was performed on the CMHPG polymer, different chelating agents, and different crosslinkers to determine the best system that works under different conditions. A fracturing fluid system with high viscosity and minimum scale caused was identified. The system's performance was assessed through core flooding experiments conducted on Berea sandstone and Scioto core samples, measuring gelation and breaking with Differential Scanning Calorimetry (DSC) to determine suitable treatment times and temperatures, considering both instant and delayed crosslinkers. The efficiency of chelating agents in capturing cations was evaluated using Differential Scale Loop (DSL) and Inductive Coupled Plasma (ICP) techniques, leading to the identification of the most effective chelating agent. The study is a field application of using SW instead of freshwater in hydraulic fracturing treatments to save freshwater water and reduce costs and efforts. This research successfully developed an optimal fracturing fluid system compatible with SW and can be utilized under different conditions. This system overcomes high salinity issues, including scale, component compatibility, and stability issues.
