Ce présent travail consiste à établir une étude de diagnostic et de réhabilitation du réseau d'alimentation en eau du village KEFRIDA commune de TASKERIOUT (wilaya de Bejaia).Après avoir récolté les données concernant le site et le système d'alimentation existant, on procédé à l'estimation des besoins actuels et futurs, ensuite le diagnostic physique dont on faitsortir toute les insuffisances et le dysfonctionnement du réseau, ce qui nous a permis dedimensionner les réservoirs et les conduites d'adduction. Par la suite on a remplacé lespompes des stations de pompage avec celle qu'on a choisi, puis on a procédé à la vérificationde l'apparition du phénomène du coup de bélier, à la fin, nous avons élaboré un systèmed'information géographique servant de base de données pour optimiser la gestion ultérieur duréseau.

Witchweeds and broomrapes are root parasitic weeds that represent one of the mainthreats to global food security. By drastically reducing host crops' yield, the parasitesare often responsible for enormous economic losses estimated in billions of dollarsannually. Parasitic plants rely on a chemical cue in the rhizosphere, indicating thepresence of a host plant in proximity. Using this host dependency, research in parasiticplants focuses on understanding the necessary triggers for parasitic seeds germination,to either reduce their germination in presence of crops or provoke germinationwithout hosts (i.e. suicidal germination). For this purpose, a number of syntheticanalogs and inhibitors have been developed and their biological activities studied onparasitic plants around the world using various protocols. Current studies are usinggermination-based bioassays, where pre-conditioned parasitic seeds are placed in thepresence of a chemical or plant root exudates, from which the germination ratio isassessed. Although these protocols are very sensitive at the chemical level, the germinationrate recording is time consuming, represents a challenging task for researchers,and could easily be sped up leveraging automated seeds detection algorithms. In orderto accelerate such protocols, we propose an automatic seed censing tool usingcomputer vision latest development. We use a deep learning approach for object detectionwith the algorithm Faster R-CNN to count and discriminate germinated fromnon-germinated seeds. Our method has shown an accuracy of 95% in counting seedson completely new images, and reduces the counting time by a signi cant margin,from 5 min to a fraction of second per image. We believe our proposed software \SeedQuant" will be of great help for lab bioassays to perform large scale chemicalsscreening for parasitic seeds applications.

Onjective: To evaluate the magnitude of prostate cancer in the North West-Bank, and to shade light on risk factors affecting its distribution.Design /Methods: In a descriptive and retrospective study, we conducted a large study among hospitalized patients. Data were collected from Teaching Hospitals (Al Watani, Beit Jala and Jinnen hospitals), during the period (1998-2006). The total population number were 750.000, of whom 70.000 men, 40 years or older were our target. Analysis based on patient admissions, and statistical methods were (ANOVA Test, T-test, Correlation, Chi squire test, Descriptive statistics and frequencies and percentile methods).Results: 78 prostate cancers were reported with incidence rate of 10.4 per 100.000 populations. We revealed that the majority of patients (64.1%) were diagnosed in Nablus and the lowest (6.4%) in Tulkarem city The highest percentage was among: [Non-smokers vs. smokers (61.5% vs 37.2% respectively), industrial workers vs. Doctors (42.3% vs 5.1%), families of seven children or over vs. less than three (56.4% vs. 5.1%), patients over 65 years, with high PSA serum levels (20ng/ml or over), (64.1%)]. Person Chi Square df, significant values of PSA categorized and dependent variables (Occupation, no. of children and Age), showed a Pearson correlation and statistical significance at P-Value = 0.05 which was respectively (0.016, 0.018, 0.003). Significant relationship was found between age and infection (P-value = 0.032) and between cancer stage and age (0.021).Conclusion: Prostatic carcinoma in the West-Bank, disproportionately strikes in different towns in West-Bank, with high prevalence in Nablus and low prevalence in Tulkarem. This prevalence is low compared to Western Countries despite the high intake of calories

We live in a mathematical world. In such a world, a lack of mathematical engagement closes many doors to productive futures. Research shows that the strategic use of instructional technology positively impacts student engagement in mathematics. Based on The Sociocultural Theory of Engagement, this mixed-method research aims to identify the effectiveness of using GeoGebra software for teaching Geometry lessons. The current quasi-experimental research addresses the impact of using GeoGebra on the level and type of the three dimensions of students' engagement "cognitive, behavioral, and affective" of grade eight students. Results show that implementing GeoGebra could be a catalyst for student engagement in geometry lessons. Overall, students have positive attitudes towards GeoGebra integration and feel that it has positive impacts on learner satisfaction, promotes engagement, and facilitates academic success. These findings are essential due to the technological shift that schools are currently facing.

ملخص:لكل رواية مكان لا يمكن الاستغناء عنه، لأنه يشكل سلسلة من الأحداث تحركها شخصيات في زمن معين، فهو ذروة العمل الروائي.يكتسب المكان أهمية كبيرة في النص الروائي فلا يتحقق إلى بوجوده، ويقوم المكان بعدة وظائف أهمها: تكوين إطار الحدث، وتحريك خيال القارئ لتصوير الأمكنة، انطلاقا من ذلك سنقوم بدراسة دلالة المكان في رواية الفيل الأزرق الصادرة عن دار الشروق، القاهرة 2012، متناولين ما يلي:الفصل الأولالنظري وفيه مفاهيم متعلقة بالمكان من حيث المفهوم والأهمية والدلالات، أما الفصل الثاني التطبيقي فهو دراسة الأماكن المفتوحة والمغلقة بالإضافة إلى تأثير المكان في البعد النفسي.

In this thesis, a measurement of the single top quark mass produced in the t-channel is presented, using the data sample recorded recently in 2015 with the ATLAS detector at the LHC, at a centre of mass energy of√s= 13 TeV and corresponding to an integrated luminosity of 3.2fb−1. The selected events contain one charged lepton (electron or muon), missing transverse energy, and two jets with high transverse momentum with one of them beingb-tagged.The template method is used to extract the top quark mass from the distribution of the invariant mass of the lepton and the-jet (m(`b)) in the selected events. The result of the measured top quark mass is:mtop=[174.56±3.11(syst.)±1.02(stat.)] GeV.
