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.

Rock engineers widely use the uniaxial compressive strength (UCS) of rocks in designing
surface and underground structures. The procedure for measuring this rock strength has been
standardized by both the International Society for Rock Mechanics (ISRM) and American Society
for Testing and Materials (ASTM), Akram and Bakar(2007).
In this paper, an experimental study was performed to correlate of Point Load Index ( Is(50))
and Pulse Wave Velocity (Vp) to the Unconfined Compressive Strength (UCS) of Rocks. The effect
of several parameters was studied. Point load test, Unconfined Compressive Strength (UCS) and
Pulse Wave Velocity (Vp) were used for testing several rock samples with different diameters.

The present paper deals with studying the effect of electrical discharge machining (EDM) and shot blast peening parameters on work piece fatigue lives using copper and graphite electrodes. Response surface methodology (RSM) and the design of experiment (DOE) were used to plan and design the experimental work matrices for two EDM groups of experiments using kerosene dielectric alone, while the second was treated by the shot blast peening processes after EDM machining. To verify the experimental results, the analysis of variance (ANOVA) was used to predict the EDM models for high carbon high chromium AISI D2 die steel. The work piece fatigue lives in terms of safety factors after EDM models were developed by FEM using ANSY
... Show MoreThe estimation of the parameters of linear regression is based on the usual Least Square method, as this method is based on the estimation of several basic assumptions. Therefore, the accuracy of estimating the parameters of the model depends on the validity of these hypotheses. The most successful technique was the robust estimation method which is minimizing maximum likelihood estimator (MM-estimator) that proved its efficiency in this purpose. However, the use of the model becomes unrealistic and one of these assumptions is the uniformity of the variance and the normal distribution of the error. These assumptions are not achievable in the case of studying a specific problem that may include complex data of more than one model. To

The aim of this study is to propose reliable equations to estimate the in-situ concrete compressive strength from the non-destructive test. Three equations were proposed: the first equation considers the number of rebound hummer only, the second equation consider the ultrasonic pulse velocity only, and the third equation combines the number of rebound hummer and the ultrasonic pulse velocity. The proposed equations were derived from non-linear regression analysis and they were calibrated with the test results of 372 concrete specimens compiled from the literature. The performance of the proposed equations was tested by comparing their strength estimations with those of related existing equations from literature. Comparis

The present paper sheds light on irony as one of the most important and most common linguistic phenomena in modern linguistics, in general ,and in discourse in particular, whether it is (political, literary, journalistic, etc.). When irony is used correctly or positively, it paves the way for the speaker to gain the approval of other parties participating in the dialogue and dissolve barriers between them. It is a simple multi-functional linguistic style and an expression of one’s meaning by using language that normally signifies the opposite according to the context and the situation. Therefore, it is necessary to study its characteristics, define its functions and traces the extent of
