    Resveratrol as a phyto-estrogenic polyphenolic compound extracted from red grapes, has a calorie restriction effect on colorectal cancer cells. It stimulates the metabolic re-programming of cells from the anaerobic glycolysis into oxidative respiration. So that it is called to be a glucose deprivation mimic drug with a chemo- preventive and chemo- therapeutic effects. The calorie restriction effect of resveratrol is the deriving force for the enhanced cytotoxicity and apoptosis and the reduced angiogeneis of colorectal cancer cells.

    The urinary bladder cancer (UBC ) are most common type of cancer of the urinary tract. It is regarded as the second and the fourth most common cancer types for males in Iraq and in the United State of America (USA) respectively and as tenth and eleventh most common cancer types for females in both Iraq and USA respectively. HER2/neu protein is glycoprotein produced by HER2 gene which lies in 17q21 (long arm of chromosome 17). This glycoprotein is normally found in lung, breast, urinary bladder, prostate and stomach, and its cytoplasmic portion has enzymatic function (tyrosine kinase activity). This receptor is responsible for the cell survival, normal cell growing and inhibition of apoptosis. HER2/neu protein overexpression is measured by IHC, but when the result of IHC is equivocal to HER2/neu protein (+ 2), Then, HER2 gene amplification is measured by using an accurate and more practical CISH method Several clinical trials are currently investigating the benefit of HER2-targeted therapy in urothelial bladder cancer. Patients with HER2 amplified UBC could potentially profit from these therapies.

    L'ouvrage est un parcours personnel et professionnel, dans lequel je partage ma connaissance, mon expérience et quelques idées avec des collègues et des lecteurs éventuels. Cet ouvrage tente de décrire mes regards sur quelques aspects du patrimoine marocain. J¿ai commencé bien sûr par le fameux site de Sijilmassa, ainsi on a essayé de dévoiler les secrets archéologiques de cette cité à savoir sa production céramique, sa composition architecturale et son histoire. Puis j¿ai fait la liaison du Tafilalt avec Sijilmassa en faisant allusion à son habitat dit « ksourien » et à son activité potière encore active. La 3° composante tente de mettre en lumière un patrimoine archéologique et naturel de la province d¿Ifrane-Moyen Atlas. Le dernier volet concerne la description de mon expérience au sein de la BNRM surtout dans la gestion des collections et dans quelques études sur les manuscrits. C'est un témoignage de mon vécu avec des mentions d¿archéologie, d¿histoire et d¿ethnographie. Il peut être aussi comme un recours, un guide pour les futurs chercheurs. Il lance enfin un appel aux autorités marocaines et à la société civile pour mettre en valeur de ce patrimoine riche et diversifié.

    In this study, we report on the radon concentration levels, in the houses of Rafah city during summer season of the year 2016 using the CR-39 track detectors. Passive diffusion Radon dosimeters containing CR-39 solid state nuclear track detectors of good quality were used to measure Radon and its daughter's concentrations throughout Rafah city. Our sampling strategy was to distribute the dosimeters in houses in Rafah city (Tal El Soltan , Balad(Rafah camp) and El Genena) at different geographic parts of the region. These dosimeters were randomly distributed in bedroom, living room and kitchen. The (150) detectors were left for about three months during the period from June to August of 2016. The collected detectors were chemically etched by using NaOH of (6M) concentration at temperature 700C for a period of about 5 hours. Each detector was counted visually using an optical microscope with power of (40*10). Tracks in the three distinct regions of Rafah city were observed, through the area (1cm2), then average number of tracks/mm2 was detected at all the regions was 73.8 Bq/m3 (1.99 pCi/l) with a range of values between 16.5 and 150.4 Bq/m3 (0.44 and 4.06 pCi/l).

    La Tunisie et la France ont connu, ces dernières décennies, de profondes mutations économiques et des transformations des rôles familiaux qui ont contribué aux changements des modes de vie des acteurs sociaux. En Tunisie, des conflits identitaires ont émergé avec l¿interpénétration des territoires de la masculinité et des territoires de la féminité, auparavant fixés et respectés selon une hiérarchie sociale, familiale et sexuelle. Les femmes ont fait irruption dans la sphère publique en participant à la vie active et en contribuant à la prise de décision. Certaines portent le voile qui revête changements sociaux et volonté d¿affirmer son identité face à la globalisation. En France, la donne est autre car il y a un nouveau visage de l¿islam où les jeunes, qui sont frustrés et se sentent exclus socialement, ont la volonté d¿être reconnus comme Français et Musulmans. Pourquoi ce choix et comment affirment-ils leur identité arabo-musulmane dans un pays occidental ? Une étude comparative s'impose pour comprendre l'islam dans ces deux pays.

    Exposure to ultraviolet (UV55) radiatn may cause the significant degradation of many materials. UV radiation causes photooxidative degradation which results in breaking of the polymer chains, produces free radical and reduces the molecular weight, causing deterioration of mechanical properties and leading to useless materials, after an unpredictable time. Polystyrene (PS), one of the most important material in the modern plastic industry, has been used all over the world, due to its excellent physical properties and low-cost. When polystyrene is subjected to UV irradiation in the presence of air, it undergoes a rapid yellowing and a gradual embrittlement. The mechanism of PS photolysis in the solid state (film) depends on the mobility of free radicals in the polymer matrix and their bimolecular recombination. Free hydrogen radicals diffuse very easily through the polymer matrix and combine in pairs or abstract hydrogen atoms from polymer molecule. Phenyl radical has limited mobility. They may abstract hydrogen from the near surrounding or combine with a polymer radical or with hydrogen radicals.

    This document seeks to present knowledge about the students, the learning process, and mainly about classroom instruction to both current and future teachers. Teaching is one of the important jobs where the teacher plays the roles of: a leader, an effective speaker, a quick diagnostician, a tactful diplomat, and a firm but fair disciplinarian. Teachers have to be "on" all the time and they do not leave their jobs behind when they go home at the end of the day. Good teachers know their subject matter and have mastered pedagogical skills. They accomplish all the tasks involved in effective instruction with warmth, enthusiasm, and caring. Good teachers are also critical thinkers and self-regulated and use educational psychology¿s principles when making a decision and when teaching. They combine research and common sense. In the same sense; the field of educational psychology is the systematic study of learners, learning, and teaching. It focuses on the processes by which information, skills, values, and attitudes are communicated between teachers and students in the classroom and on applications of the principles of psychology to instructional practices.

    Le point de départ de ma réflexion était les pratiques de cage et Schafer. mon approche utilise des outils d¿analyse de l¿histoire de l¿art, de la philosophie et de l¿esthétique, pour rendre compte des pratiques du paysage sonore et du son. L¿objectif de cette méthode est l¿assemblage d¿une histoire, un état de l¿art et une cartographie du son et de ses déploiements. Je tiens à souligner le statut des auteurs étudiés. Ce sont les pionniers du son, chacun de ces auteurs cristallise, dans ses pratiques du son, des manières de l¿écouter ou de le construire. Il s¿agit donc d¿interroger ce geste spécifique qui consiste à séparer le son de la musique pour en faire une catégorie à part. Cette catégorie qui évolue dans les lieux situés en marge, un seuil sur une frontière entre deux bords (un bord canonique relativement stable celui de Murray Shafer et un bord mobile celui de cage). Pour ce travail, j¿ai choisi d¿analyser les pensées et les pratiques du son, avec pour objectif d¿identifier la manière selon laquelle les auteurs (théoriciens / performeurs) construisent leur paysage sonore. mots clés:son, trangression, immanence ,art , paysage sonore , perfermance, Cage, schafer

    Preface Why the book? Who is this book for? This book covers practical issues faced by Educationists and English Language teachers in the classroom environment. It covers the basics of psycholinguistics, laying the foundations on which to build upon and develop linguistic performance. The aim of this book is to provide educationists and teachers with a basic framework of strategies and approaches, leaving them to generate their own ideas and explore a plethora of possibilities. It is not intended that this book be read in its entirety, but rather that you choose those topics which hold particular interest for you. It is also great as a point of reference for psychologists ,parents ,teachers and graduate students interested in psychology which will be by no means the definitive guide to English Language Teaching, Explanations and ideas are presented, as far as possible, in simple everyday English. Where it has been necessary to use Psychology and Linguistics terminology, I have generally used more traditional terms that are well known and easy to understand.

    In the Iranian Criminal Procedure Code, the victim has been operating beyond the control. Nowadays, protecting the victim's rights directly in the line of protecting the community and accused is another important objective of the criminal procedure. This research is descriptive-analytic by gathering information through library collection. The purpose of this research is to investigate and analyze the criminal procedure law for protecting the rights of the victim, witness, informed, and accused family. After reviewing the legislature's support for the victim's rights, we have come to the conclusion that the Criminal Procedure Code includes supportive programs. It also protects intuition and advocacy programs such as: non-face-to-face encounter between witnesses and informants with the plaintiff or defendant, the failure to disclose identity or housing information of witnesses and informants, the use of information technology in martyrdom audits, and obtaining information, support checking against threats or possible risks, providing for and paying for losses, investigating separately from the presence of witness, the prohibition of notifying witnesses or informants.
