Breast masses have become common in women; such masses may pose a potential threat to women especially when it belongs to breast cancer. Breast cancer is one of the leading causes of cancer death in women worldwide. This is a descriptive hospital-based study, conducted at National Ribat University hospital, the study aimed to characterize Breast malignant lesions using breast Imaging Reporting and Data System (BIRAD) and ultrasonography. 71 suspected patients were enrolled in the study; all of them were scanned with ultrasound machine (Philips / Neusoft) with 10 MHZ probe. BIRADS category lesions were diagnosed in all 71 women after extensive conventional imaging work-up. The result of the study showed that 49 patients were found to be positive after conducting histopathology examination, indicating a sensitivity of 97% and a positive predictive value of 96%. Specificity was found to be 95% and the negative predictive value was found to be 95% as well. 23 (30.99%) of participants showed no solid mass while 48 (69.01%) showed a solid mass by using Ultrasonography. 39 patients (54.93%) showed hypoechoic echo pattern, while 3 (4.23%) showed an anechoic echo pattern. Isoechoic and complex echo patterns were 1 (1.41%) and 5 (7.04%), respectively. Regarding shape; 31 (43.66%) showed irregular lesion. Furthermore, Margin of the lesions of patients was found to be speculated in 18 (25.35%), while 13 patients (18.31%) showed micro-lobulated margins.The study indicated that the assessment of breast lesions with the use of the Breast Imaging Reporting and Data System ultrasound lexicon showed a significant diagnostic reliability for description of breast cancer.

Dans le cadre de notre recherche, nous avons effectué une analyse bibliographique approfondie, en mettant l'accent sur la résolution de problèmes de commande optimale dans des systèmes dynamiques hybrides à commutation autonomes. Ce type de problème est étroitement lié au célèbre principe du maximum de Pontryagin. Notre étude se concentre spécifiquement sur l'optimisation du fonctionnement d'un système de climatisation. L'objectif est de maintenir une température confortable tout en optimisant l'efficacité energétique en minimisant la consommation d'énergie lorsque cela est possible.En résumé, notre travail s'inscrit dans le domaine de la commande optimale, où nous cherchons à résoudre des problèmes de contrôle pour améliorer l'efficacité opérationnelle du climatiseur en minimisant les variations de température et en optimisant l'utilisation de l'énergie. Cette approche combine des concepts de la théorie de la commande optimale et de la recherche opérationnelle pour atteindre ces objectifs

Previous literature on child marriage has primarily focussed on consequences, reported reasons, as well as the medical, educational, legal and human rights dimensions pertaining to the issue. Little has been published on attempts to analyze this discourse, especially taking into account the role of imperialism in the construction and maintenance of the â poor, colored child bride of the developing world.â This project, thus, conducts a discourse analysis of child marriage and subsequently analyzes the effects of imperialism embodied therein. It stresses the power possessed by first world elites, who finance and institutionalize â child marriageâ projects and research to maintain the status quo. The lack of self-reflexivity of these â Subject Watchersâ is clear and therefore, this project speaks to those who speak â forâ and about girls like Nujood Ali. Their speaking is purportedly done for the purpose of acquiring knowledge about the monolithic entity of embodied by the child bride and her community, with the intention of eradicating the practice of child marriage. Given this imposition of imperialism, however, the thesis concludes that real access to (the subaltern group of) child brides is impossible.

During the last 15 years Algeria has known a desinsdustrialisation which touched the public sector. It was the result of the diminution of production and productivity. the whole is accompanied with theaugmentation of the level of jobless.Nowadays,another positive modern industrial dynamic is emerging which contributes to the one hand and to the openness of new perspectives on the other hand.In this work, we approved the topic of emerging industries in the”wilaya of Constantine», reality and perspectives, this work is structured on three parts. In the first, organized in three chaptersWe treat; industry and emerging industries with general notions of industry, emerging industries and amenagement with historic and territorial diagnostic, the second part intitled”the current situation ofemerging industries in the wilaya of Constantine «an immentory established in public and privateenterprise(repatition,volume,production).We treat mechanic and alimentaire and we retain”l’entreprise national des travaux public «as a model situated in the district of Ain smara and”SAFILAIT”of milk dairyproducts also at the same district. We illustrate this thematic with some examples of some emerging industries in Algeria and PME enterprises.The third part «emerging industrial perspectives and taken from other lesson countries” experiences. they treat some realities and perspectives and in addition to the relation between emerging industries and thedurable development.This work shows the existence of urbain hierarchy in the”wilaya of Constantine”

تتناول هذه الدراسة إمكانية تفعيل التكامل في المغرب العربي عندما تتحقق مستويات سياسية، اقتصادية واجتماعية وثقافية في التدرج لتحقيق التحول نحو الديموقراطية التي أصبحت أحد أهم وحدات تحليل الأنظمة السياسية، والمقارنة بينها أين تجلت أهمية الوعي بالتحولات والتغيرات السياسية كأسس عاجلة لإعادة آلية عمل هذه الأنظمة بإشراك كل الفواعل في صناعة القرارات المرتبطة بالسياسة الخارجية سيما قرار التكامل المغاربي من عدمه، أين تعرف أنظمته السياسية انسدادا كبيرا في تجسيد التكامل الإقليمي وعجزا وفشلا في تحقيق الديموقراطية، ما يعني البحث في حدود العلاقة بين تفعيل تكامل في المغرب العربي وبين مسار التحول نحو الديموقراطية في المنطقة

This thesis evaluates the use of work sampling in predicting construction labor productivity. It also considers the effect of complexity level, crew size, and skill level on the relationships between productivity and work sampling categories. This study tests three hypotheses: productivity increases as the effective work category increases, productivity increases as the effective work category decreases, and effective work category increases as the ineffective work category decreases. A total of 35 field experiments of walls building were performed and filmed in this study. For these experiments, three complexity levels, two crew sizes, and two skill levels were considered. The results show that the three hypotheses are true. They also indicate that complexity and skill levels have no significant effect on the relationships advanced in the above hypotheses, but the three relationships are affected by the crew size. In spite of the support of the above hypotheses, the results indicate that work sampling is not a very strong predictor of construction labor productivity.
