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.
Thin films of pure polycarbonate (PC) with anthracene doping PC films for different doping ratios (10, 20, 30, 40, 50 and 60 ml) were prepared by using a casting method. The influence of anthracene doping ratio on photo-fries rearrangement of polycarbonate was systematic investigated. Furthermore, pure PC and anthracene doping PC films were irradiated via UV light at a wavelength (254 nm) for different periods (5, 240, 288, and 360 hrs). The photo-fries rearrangement occurring in pure PC and anthracene doping PC films were monitored using UV and FTIR spectroscopies. The photo-fries rearrangement leads to scission the carbonate linkage and formation phenylsalicylate and dihydroxybenzophenes. The result of the UV spectrum confirms disappea

This research provides a study of the virtual museums features and characteristics and contributes to the recognition of the diversity of visual presentation methods, as the virtual museums give the act of participation and visual communication with programs at an open time, so that it would contribute to reflection, thinking and recording notes, developing the actual and innovative skills through seeing the environments. The study has been divided into two sections the first one is virtual museum techniques. The techniques were studied to reach the public and are used remotely by the services of personal computers or smart phones being virtual libraries that store images and information that was formed and built in a digital way and how

Objectives To tailor composites of polyethylene–hydroxyapatite to function as a new intracanal post for the restoration of endodontically treated teeth (ETT). Methods Silanated hydroxyapatite (HA) and zirconium dioxide (ZrO2) filled low-density polyethylene (LDPE) composites were fabricated by a melt extrusion process and characterised using infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The flexural strength and modulus were determined in dry state and post ageing in simulated body fluid and fractured surfaces analysed by SEM. The water uptake and radiographic appearance of the experimental composites were also measured and compared with a commercially known endodontic fibre

Show MoreIn this paper, a new third kind Chebyshev wavelets operational matrix of derivative is presented, then the operational matrix of derivative is applied for solving optimal control problems using, third kind Chebyshev wavelets expansions. The proposed method consists of reducing the linear system of optimal control problem into a system of algebraic equations, by expanding the state variables, as a series in terms of third kind Chebyshev wavelets with unknown coefficients. Example to illustrate the effectiveness of the method has been presented.

Experimental and numerical studies have been conducted for the effect of injected air bubbles on the heat transfer coefficient through the water flow in a vertical pipe under the influence of uniform heat flux. The investigated parameters were water flow rate of (10, 14 and 18) lit/min, air flow rate of (1.5, 3 and 4) lit/min for subjected heat fluxes of (27264, 36316 and 45398) W/m2. The energy, momentum and continuity equations were solved numerically to describe the motion of flow. Turbulence models k-ε was implemented. The mathematical model is using a CFD code Fluent (Ansys15). The water was used as continuous phase while the air was represented as dispersed. phase.
