يُعد التنمر ظاهرة إجتماعية قديمة موجودة في جميع المجتمعات سواء أكان المجتمع صناعيًا أم ناميًا، كما يُعد من المفاهيم الحديثة نسبيًا، وربما يرجع لحداثة الإعتراف به نوعًا من أنواع العنف فضلاعن ندرة الدراسات التي تناولته وعدم وجود معيار محدد لتحديد السلوك الذي يعد تنمرًا أم عابرًا، لقد بدأ الأهتمام بدراسة التنمر في سبعينات القرن الماضي وأصبح موضعًا يحضى بأهتمام العديد في مختلف البلدان، وفي عصرنا الحالي تطورت الظاهرة الإجرامية تطورًا ملحوظًا سواء في أسلوب إرتكابها أو مرتكبيها وكل ذلك يرجع إلى التقدم السريع في ثورة المعلومات والإتصالات، فظهرتْ الجرائم الإلكترونية ومنها جريمة التنمر الإلكتروني، وفي نطاق الجريمة الإلكترونية، أختلف الفقه والقضاء في تحديد مسؤولية مزود خدمة الإنترنت وفقًاً لطبعية عمله المتمثل بمدى الرقابة التي يقوم بها على المحتويات غير المشروعة التي تتم عبر الخدمة التي يقدمها في الجرائم الإلكترونية ومنها جريمة التنمر الإلكتروني Bullying is considered an ancient social phenomenon that has existed in all societies for a long time, whether the society was industrialized or developing. Recently, bullying was recognized as a form of violence. Additionally, the interest in studying bullying began in the seventies of the last century and became a topic of interest in many countries around the world. nowadays, the criminal phenomenon has developed remarkably, both in the way it is committed or its perpetrators, and all this is due to the rapid progress In the information and communication revolution, cybercrimes appeared, including the cyber-bullying crime In addition, Jurisprudence and the judiciary have differed in determining responsibility of the internet service provider according to the nature of its work, which is the extent of control it performs on the illegal content that is carried out through the service it provides in cybercrime, including the cyberbullying crime. Le harcèlement est un phénomène social ancien présent dans toutes les sociétés, qu'elles soient industrielles ou en développement. Il est également considéré comme un concept relativement moderne en raison de sa reconnaissance récente en tant que forme de violence, ainsi que de la rareté des études qui l'ont abordé et de l'absence du critère spécifique pour déterminer quel comportement est considéré comme du harcèlement ou toléré. L'intérêt, pour l'étude du harcèlement a commencé dans les années 70 du siècle dernier et est devenu un sujet d'intérêt pour de nombreuses personnes dans différents pays. De nos jours, le phénomène criminel s'est sensiblement développé, que ce soit dans sa manière de se produire ou chez ses auteurs, et cela est dû aux progrès rapides de la révolution de l'information et de la communication. Les crimes électroniques, y compris le harcèlement électronique, ont émergé dans le cadre de la cybercriminalité. Dans ce contexte, les juges et les autorités judiciaires ont divergé dans l'établissement de la responsabilité du fournisseur d'accès internet en fonction de la nature de son travail, qui consiste en l'étendue de son contrôle sur les contenus illégaux qui se produisent par le biais du service qu'il fournit dans les crimes électroniques, y compris le harcèlement électronique.
Calculating the Inverse Kinematic (IK) equations is a complex problem due to the nonlinearity of these equations. Choosing the end effector orientation affects the reach of the target location. The Forward Kinematics (FK) of Humanoid Robotic Legs (HRL) is determined by using DenavitHartenberg (DH) method. The HRL has two legs with five Degrees of Freedom (DoF) each. The paper proposes using a Particle Swarm Optimization (PSO) algorithm to optimize the best orientation angle of the end effector of HRL. The selected orientation angle is used to solve the IK equations to reach the target location with minimum error. The performance of the proposed method is measured by six scenarios with different simulated positions of the legs. The proposed

In the present work, a D.C. magnetron sputtering system was
designed and fabricated. This chamber of this system includes two
coaxial cylinders made from copper .the inner one used as a cathode
while the outer one used as a node. The magnetic coils located on
the outer cylinder (anode) .The profile of magnetic field for various
coil current (from 2Amp to 14Amp) are shown. The effect of
different magnetic field on the Cu thin films thickness at constant
pressure of 7x10-5mbar is investigated. The result shown that, the
electrical behavior of the discharge strongly depends on the values
of the magnetic field and shows an optimum value at which the
power absorbed by the plasma is maximum. Furthermore, the

The products of composites material are very sesetive to many variables, such as manufacturing process, additive materials, …. etc. Filler or additive plays a major role to determine the formation of the properties and behavior of the composites. In this study, polyethylene terephthalate-based compounds were produced and characterized. The work is concerned to prepare samples of Polyethylene terephthalate (PET) - zinc-ferrite (ZnFe2O4) with different addition ratio as zinc-ferrite (1, 2, 5, 10, 15 and 20) wt% obtained from mixing the solution with a hot pressing method applied under optimum conditions. The densities of the composites for all samples were calculated. Through the work the diffusion of zinc-ferrite i

Background: Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosa diseases characterized by recurrent, shallow, round or oval painful oral ulcers surrounded by inflammatory erythematous halos, the condition is chronic and self-limiting in immunocompetent patients. Aim of the study: to investigate the serum vitamin D levels in Iraqi female patients with RAS and the relationship between vitamin D levels and the severity of RAS. In this cross sectional study 30 female patients with idiopathic RAS, and 30 age and sex matched healthy controls were included, the severity of RAS is assessed by the number of oral aphthous ulcers in each attack and the frequency of attacks. Serum 25(OH) D levels were determined by the Enzy

Ex-situ bioremediation of 2,4-D herbicide-contaminated soil was studied using a slurry bioreactor operate at aerobic conditions. The performance of the slurry bioreactor was tested for three types of soil (sand, sandy loam and clay) contaminated with different concentration of 2,4-D, 200,300and500mg/kg soil. Sewage sludge was used as an inexpensive source of microorganisms which is available in large quantities in wastewater treatment plants. The results show that all biodegradation experiments demonstrated a significant decreases in 2,4-D concentration in the tested soils. The degradation efficiency in the slurry bioreactor decreases as the initial concentration of 2,4-D in the soils increases.A 100 % removal was achieved at initial con

Respiratory tract infections in sheep are among the important health problems that affect all sheep ages around the world. Nine bacterial isolates obtained from sheep with respiratory tract infections were selected to be used in the current study. The isolates included 3 Staphylococcus aureus, 4 Klebsiella pneumoniae, and 2 Pseudomonas aeruginosa. Following the primers design by the Primer3Plus software tool and optimization of the conventional polymerase chain reaction (PCR), the primers were validated for their use in the multiplex PCR experiments. The MFEprimer program was used to check the suitability of the primer set combinations for multiplex PCR. The MFEprimer software was successful in designing the multiplex-PCR experiments and de

In this thesis, we introduced the simply* compact spaces which are defined over simply* open set, and study relation between the simply* separation axioms and the compactness were studied and study a new types of functions known as αS^(M* )- irresolte , αS^(M* )- continuous and R S^(M* )- continuous, which are defined between two topological spaces. On the other hand we use the class of soft simply open set to define a new types of separation axioms in soft topological spaces and we introduce the concept of soft simply compactness and study it. We explain and discuss some new concepts in soft topological spaces such as soft simply separated, soft simply disjoint, soft simply division, soft simply limit point and we define soft simply c

Such difficulties arise from the existence of the magnetizing inrush phenomenon. Therefore, it is necessary to recognize between inrush current and the current arise from internal faults. In this paper, two approaches based on wavelet packet transform (WPT) and S-transform (ST) are applied to recognize different types of currents following in the transformer. In WPT approach, the selection of optimal mother wavelet and the optimal number of resolution is carried out using minimum description length (MDL) criteria before taking the decision for the extraction features from the WPT tree
