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.
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

Colorectal cancer is the world's 3rd most frequent malignant neoplasm and the 4th most common cancer in Iraq. Leptin and Adiponectin are two major Adipocytokines produced by adipose cells that have opposite effects on the formation of colorectal tumors. Leptin induces tumor growth and metastasis, whereas Adiponectin inhibits it. 1,25-Dihydroxyvitamin D controls and limits cancer cell proliferation, differentiation, and survival. Vitamin C deficiency, on the other hand, has been regularly detected in cancer tissues and has potent anti-cancer properties. The purpose of this study was to look at the biochemical role of circulatory Adipocytokine levels (Adiponectin and Leptin) as well as the anti-cancer potentials of Vi

The present work aimed to investigate the neuraminidase (nan1) gene expression in 32 different clinical isolates of Pseudomonas aeruginosa to explore the role of the enzyme in different types of infection and might give a better understanding of host cell-pathogens interaction. In addition, the effect of monosaccharide D-mannose on neuraminidase gene expression in eight isolates was studied by utilizing a reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The results demonstrated that the highest expression of nan1 gene was in otitis samples (208,913.81) which were significantly higher than that from other infections (P < 0.01). While, the concentrations of gene copies obtained from urin

In this article, we introduce and study a class of modules in which all its nonzero endomorphisms have non-s-essential kernels, named, strongly -nonsigular. We investigate some properties of strongly -nonsigular modules. Direct summand, direct sums and some connections of such modules are discussed.
This study is a try to compare between the traditional Schwarzschild’s radius and the equation of Schwarzschild’s radius including the photon’s wavelength that is suggested by Kanarev for black holes to correct the error in the calculation of the gravitational radius where the wavelengths of the electromagnetic radiation will be in our calculation. By using the different wavelengths; from radio waves to gamma ray for arbitrary black holes (ordinary and supermassive).
