Une étude de la diversité floristique et phytogéographique de la série de végétation à Cedrus atlantica a été menée à Tikjda, au parc national du Djurdjura, il est situé en bioclimat humide à hiver frais. Lors de cette étude, 142 relevés floristiques ont été réalisés qui appartient à 42 familles botaniques et 116 genres en suivant la méthode d’échantillonnage (comptage). D’après les résultats on déduit une nette dominance de l’ensemble méditerranéen avec 89 (62.67%) espèces suivies par 29 (20.42%) espèces nordiques, le site est remarquable par la présence de 16 (11.27%) espèces endémiques ce qui montre l’importance de la phytodiversité de ce parc. L’analyse du spectre biologique montre une dominance des Hémicryptophytes avec 40.2% sur les autres types biologiques, grâce à la pluviosité et le froid qui règne surtout en hiver. Les menaces qui pèsent sur la flore de notre zone d’étude sont multiples, donc il est nécessaire d’intégré un plan de gestion écologique et durable qui permet de sauver les parties de forêts qui subsistent, ou de préserver quelques zones qui sont encore restées miraculeusement à l’abri de ces destructions.

The study of the special curves of solar PV modules are of great importance in developing cells and increasing their capacity, hence the idea of this thesis that was intended to predict the current-voltage curve for solar PV module by developing a new developed model that relies on random forest technique in training and testing data using MATLAB program. The random forest technique is a machine learning method, where this technique relies on decision trees (classification trees, regression trees). The regression trees were released in the new proposed model to predict the output variable (PV module output current), depending on a set of inputs represented by five parameters (ambient temperature, solar radiation, PV DC voltage, short circuit current, and open circuit voltage). This data sets were obtained by conducting several experiments on a (STF - 120P6) poly-crystalline PV module 14.0% module efficiency. Seven experiments were done on the (STF - 120P6) PV module in different values of cell temperatures and solar radiations to measure the current and the voltages by using the (I-V CURVE TRACER DEVICE). Through training and testing these data, high accuracy results were obtained for the proposed model, where the metric error values (RMSE, MAPE, and MBE), which are equal (0.04251%, 4.315097%, -0.3959%), respectively. A value of (MAPE) was used to evaluate this model and compare it with previous models that adopted different methods to predict the I-V curve of the solar PV module. These methods can be classified into offline methods and online methods. Online methods depend on real devices to extract the I-V curve as (capacitor, resistor, inductor, and switches), Offline methods represented in Artificial Intelligence methods, Random Forests technique, and the numerical methods where are used to obtain numerical solutions of a mathematical problem such as Levenberg–Marquardt method(LM), Newton–Raphson method (NRM),

The study area is located in the north western part of Algeria, which is part of the Southern Tellian field. The studied land belong to the immigrant to Tellian affinities where the upper Eocene-Cretaceous deposits belong to the Senonian unit. Their study uses multiple approaches to order lithobiostratigraphique, paleoecological and paleobiogeographic. The lithobiostratigraphique study based on planktonic foraminifera has established a new division of well-individualized biozones.The study association’s ostracods highlight eleven Paleoecologicalecozones. Regional bathymetric evolution during the Late Cretaceous indicates a transgressive phase for épibathyale area. The transition to the lower Paleocene, the water column moving towards épibathyale area up to the mésobathyale area using Paleocene. From the Paleocene and Eocene until the environment sees a lowering of sea level to the continental shelf.The study area is characterized, during the interval analyzed by two major events: First, duringthe Cretaceous-Paleocene transition denotes a considerable impoverishment of wildlife ostracods; then, during the passage Paleocene-Eocène IETM is the area marked by a fall in ostracods and even the total absence.The Oran region see appear the movements of several species that indicate local palaeobiogeographic relationship then with the regions of South Tethyan province.Definitely, the appearance of the forms from the Atlantic coast until Mediterranean shows a phase of standardization as ecological conditions that palaeobiogeographic undoubtedly due to the opening of the Atlantic.The overall palaeobathymetry evokes similarities with the global eustatic scheme: transgression-regression but with the changing rate of the C13 isotope test carbonates.

In this research I examine representations of gender and gender-based violence in some of the most prominent campaigns produced by women’s non-governmental organizations in the past decade in Lebanon. I explore the publics these representations address and how they engage them, what gender meanings these representations construct in relation to dominant gender norms, and how the rhetoric they develop reflect on social change in the Lebanese and feminist public spheres.Lebanese NGOs operate in a public sphere colored with a prevalence of patriarchal and sectarian structures, neo-liberal market relations, and an industry reliant on donor funding. In turn, this context affects campaigns and representations of gender commissioned by these NGOs. It also affects the movement for gender rights in general in regard to questioning or challenging the existing hegemonic beliefs and systems of oppression.I posit my research in the literature on NGOization and examine six campaigns on GBV against women produced in the past two years by three Lebanese NGOs: KAFA, Abaad, and Arab Foundation for Freedoms and Equality. A visual and textual examination was conducted on these campaigns including their representations and variant elements, then analysed with a feminist rhetorical criticism. In addition, semi-structured interviews were conducted with communication officers in both NGOs and advertising agencies who produced these campaigns.Research findings indicate that, first, half of the campaigns address their public by striking relatability. However, their relatable address is based on variant assumptions including reproducing middle-class experiences which reflect the campaign authors’ own middle classness. The other half of campaigns engage their public through the dramatic appeal of sensationalized classist stereotypes of womanhood and difference. Comparatively, these campaigns are not meant to address women who had been subjected to GBV, but donors with a concern for reach. Third, all campaigns in this research utilize gender in a utilitarian manner. Themes like victimhood, agency, and gender order are manipulated to construct normative to more defiant meanings for the service of campaign aims. Finally, many of the rhetoric developed in these campaigns reflect a refeudalization of the feminist public sphere for the service of private interests in relation to donors. This translates into campaigns accountable to attainable goals rather than intersectional actionable social change. Whether utilizing relatability to portray what is or dramatic appeal to introduce what could be, these representations address many aspects of dominant norms and structures, while also reproducing other aspects.

Cette étude bibliographique a évaluée les effets toxicologiques du pirimicarbe, un composé actif de la famille des carbamates, reconnu pour son activité insecticide. Dans la littérature, le pirimicarbe a été impliqué dans l'inhibition de l'enzyme acétylcholinestérase, entraînant des manifestations toxiques aiguës et subchroniques chez diverses espèces animales, incluant des symptômes cholinergiques, des altérations hématologiques et une diminution de l'activité enzymatique. Chez les rats, il induit des altérations biochimiques ainsi que des perturbations neurocomportementales. Les travailleurs exposés au pirimicarbe présentent des manifestations cholinergiques temporaires, sans effets à long terme observés. Bien que non carcinogène, le pirimicarbe peut provoquer des effets tératogènes et génotoxiques à des concentrations élevées. Il altère la fonction reproductrice masculine chez les rats et induit des comportements dépressifs et anxieux. Mots clés : Pirimicarbe, Carbamates, Insecticide, Effets toxicologiques, Animaux, Humain.

إن بناء أي مشروع اقتصادي مهما كانت طبيعته ونجاعته لا يحظى بالنجاح في غياب الأرضية القانونية والتنظيمية المرافقة له، الأمر ذاته بالنسبة للمؤسسات الناشئة التي تعتمدها الدولة الجزائرية كنمط اقتصادي بديل للنهوض بالاقتصاد الوطني. في هذا المنظور، هدفت هذه الدراسة الى تحديد الإطار القانوني للمؤسسات الناشئة وطبيعتها القانونية وشكلها القانوني الذي يتناسب مع وظيفتها وأهدافها وخلصت الدراسة إلى أن المؤسسات الناشئة تنفرد بخصوصيات متميزة تستدعي مراجعة القانون التجاري والقوانين المنظمة لمناخ الأعمال والتجارة.
