Since its invention in the early 1970, the use of demand for optical fiber has grown tremendously. The uses of optical fiber today are quite numerous. With the explosion of information traffic due to the Internet, voice, data, and ,electronic commerce, computer networks and multimedia video, the need for a transmission medium with the bandwidth capabilities for handling such vast amounts of information is paramount. Fiber optics, with its comparatively infinite bandwidth, has proven to be the solution. Optical fiber is also used extensively for transmission of data signals, these data need secure, reliable systems to transfer computer and monetary information between buildings, to the desktop terminal or computer, and around the world. The high information-carrying capacity, or bandwidth, of fiber makes it the perfect choice for transmitting signals.

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.
This book is a delicious snack to any person who wants to know how to converse in the English language in as many situations as they imagine.

This book is introducing a prayway to reduce camber in simply supported prestressed concrete girders. This camber usually produced when girders left for a period of time before installation in the site causing construction problem when casting the slab deck. There for a practical way should be presented to decrease this camber without reducing the girder capacity. The book deals with this problem by introducing prestressed strsnds in the compression zone.
This research sheds light on the practice of codeswitching in the Colleges of Dentistry, Pharmacy and Medicine of the University of Anbar. Codeswitching is defined as the use of two or more languages in communication. This study aims at examining who uses codeswitching, the teacher, the students, or both, the general purposes and specific functions of codeswitching, and the relationship between the level of English proficiency of the students and the use of codeswitching strategies.
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.
Introduction: Peptic ulcer disease (PUD) is the erosion in lining of stomach or duodenum. Predominantly caused by Helicobacter pylori infection in about 50% of the world¿s population.which can colonize in the gastric antrum of all patients producing an extensive, noninvasive inflammatory reaction in the gastric mucosa.Methods: Fortey patients newly diagnosed endoscopically with peptic ulcer disease to be allocated into group 1 treated with standard H. pylori eradication triple therapy, and group 2 patients treated with curcumin (500 mg) capsules three times daily for 14 days as an adjuvant to standard triple therapy.Results: The result showed that the use of curcumin as adjuvant therapy produced highly significant improvement in healing efficacy which was significantly distinguished in duodenal ulcer patients compared to gastric ulcer groups 2 patients (p
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.
Long before the birth of the Holy Prophet of Islam, there were frequent contacts between Arabia and Tamil Nadu. The Classical Tamil Literature bears evidence of the Arab contact with the Tamil Nadu.

In this research, the different modes of the 33-bus network were investigated with open DSS and MATLAB software. The simulation program was implemented using the colonial competition algorithm in two general sections. In the first case, loads were considered constant, and in the second case, they were probably modeled. Each of these states had sub-sections. In these sub-sections, location and measurement of photovoltaic sources were investigated. The specified objective functions were also explored separately to provide a comprehensive form of the proposed method. The results of the simulation with MATLAB with the help of open DSS indicated that by using the optimal location and measurement of the photovoltaic power plant, the system losses could be significantly reduced and the quality of the delivered power to the subscribers could be improved. By improving the voltage profile of the buses of the power system, subscribers would have a higher quality power. Finding the optimal size and place of the photovoltaic power plant using a multi-criteria objective function was investigated in this book.
This book in your hand is about the impact of segmental and suprasegmental Phonemes in Learning Speaking in English as a Foreign Language. It also based widely on phonetics and phonology in which the difficulties of pronunciation of the segmental phonemes and supra-segmental features ¿stress, intonation, pitch and rhythm etc.¿ is identified. It is also an essential guide for English learners to master their pronunciation and knowledge of English language. Inside the book, there is an argument about the interference of the first language sound system in the second language sound system and suggestions for solution.
Traditional pest management strategies could be replaced by the potential of nanotechnology as an effective and viable approach to alleviate problems pertaining to pest control given the unique characteristics of that technology, especially the metal nanoparticles. In this research, we synthesized silver nanoparticles (AgNPs), zinc oxide nanoparticles (ZnONPs) by the chemical reduction method. The instrumentation such as TEM, SEM, UV-visible spectroscopy was used to reveal the morphology and size of nanoparticles (which was the seam grain with rough ends in AgNPs and size ranged between 20-50 nm), (the shape was amorphous with sharp edges, 60-128 nm in ZnONPs) and the characterization of bought Silica nanoparticles indicates that was approximately spherical with the diameter between 20-60nm. In bioassays, larvae were exposed to a series concentration of Ag, ZnO and SiO NPs by feeding and dipping method. Mortality rates obtained with SiO, ZnO and Ag NPs at the highest concentration were 90 %,86 % and 60 %, respectively. ZnO nanoparticles reach the high percentages in inhibition of pupation and inhibition of adult formation (100% in both).
The purpose of this book is to make available to the student some fundamentals of mathematical analysis. Specifically, it is intended to make such fundamentals available in a form that meets their need in many applications, like real analysis, integration, measure theory, and representation theory. The principal point of view is to develop the basic structures of analysis, under which one can appropriately go on further in the domain of functional analysis. The book is intended to be essentially self contained and accessible to well-trained under graduated students. Its prerequisites are elementary standards from basic algebra. In writing this book, we care about doing things as little abstract as possible. So, to make easy the access to the main concepts, each section of each chapter is illustrated by simple examples and exercises, which are mostly applications to concrete problems.
The title of this book is solved examples on Advanced Engineering Mathematics. It consists of several topics from Advanced Engineering Mathematics. In it, we collect a lot of examples with their solutions. Our goal in this book how to learn, not only to solve, in that sense in each problem, we discuss more than one method, but in solving, it is sufficient to use one of them. These topics are Linear Dependence and independence, second order differential equations, Fourier series, Fourier integrals, Laplace transforms, Special functions (gamma and Beta functions), Partial differential equations and solution of differential equations in series. The book can be of use to readers of various professions dealing with applications of mathematics in their current work. The subject matter is presented in a very systematic and logical manner.
Developing valid measures of abstract constructs is essential to the advancement of psychological and educational research. The most common practice in scale development consists of an administering a group of items intended to measure the same construct and subsequently aggregating the responses to form total a scale value. Besides, reliability of scores, number of underlying constructs, and scale construction practices should empirically test the assumptions of equal item weighting and the linear treatment of scales can represent the quantity of a trait held by an individual. Based on the perspective of using Rasch Model as a model in one sense in that it represents the structure which data should exhibit in order to obtain measurements from the data; i.e. it provides a criterion for successful measurement. As such, measuring the lecturers¿ beliefs needs a measurable instrument to be developed and tested in order to clarify how beliefs reform lecturers¿ teaching functions and practices. This book is mainly on how to use Rasch Model analysis as a powerful tool for evaluating constructs validity of the instrument for interpretation the lecturers¿ beliefs on teaching functions.
Sudan is considered a multi ethnic, regional, cultural and religious ingredients country. As a result of this diversity the ingredients engaged in numerous civil wars. The conflict of South Sudan was the first and largest; In return, many efforts were made to solve this conflict; the last was the CPA signed in Nivasha in 2005; which put an end to the South war, and granted the people of South Sudan the right of self-determination by the end of the transitional period in 2011. In the end, the Southerners chose separation and declared the South Sudan State. The secession was the result of several factors which collaborated together and both North and South Sudan were affected negatively. This discussion targeted to research these means by its internal and external sections; also the result of secession of both sides. The study also targeted the analysis and evaluation of the CPA and quest of the possibility of unity between North and South once more.
Writing is not a simple activity as a few people may consider; it is a sort of challenging task, when it is compared with various language abilities, such as reading, listening and speaking which needs a lesser amount of effort. Writing is a significant challenging process, especially for second language learners and foreign language learners. Most language learners at all stages feel that writing is probably the most challenging language ability to be mastered and it is a progressing advanced skillfulness in contrast with other capacities. Writing in English is supposed to stand as a critical talent for accomplishment in the current international economy. Several specialists would go further to say that when there is a lack of experts in English reading and writing, a job would be slightly inadequate if it includes doing business in English-speaking countries at even a fundamental level. Consequently, it is suggested that English writing becomes a need for any comprehensive director who needs to develop his or her career in the universal market.
Bioinformatics has been evolved into a critical inter-disciplinary field that benefits studies in both molecular biology and computer science. On the one hand, it grants the possibility to comprehend biological information and process in a more effective and efficient way by employing computational technologies to extracting knowledge from dense amounts of intermixed biological data; on the other hand, it provides a new and complex domain for researching advanced algorithms and techniques for data analysis. Nevertheless, bioinformatics also poses a great challenge to grasp for both computer science and biology majors due to its interdisciplinary and advanced natures. As many bioinformatics software tools are generally involved in analysis tasks, scientists are more and more requiring that these heterogeneous bioinformatics tools be integrated in a uniform way. They are also requiring graphical user interfaces of these tools, and the ability to compose workflows without much programming effort.
In the last 15¿20 years, pulsed laser deposition (PLD) has emerged as one of the most popular and intrinsically simple techniques for depositing a wide range of the most exciting materials being explored for next generation applications. Such sustained popularity is due to the inherent versatility, flexibility, and speed of a process that can be applied to essentially any material, from simple metals, through binary compounds, to multi-component high-quality single crystals. Pulsed laser deposition had several characteristics that made it remarkably competitive in the complex thin-film research arena as compared to other film growth techniques. These principle attractive features were stoichiometric transfer, and simplicity in initial setup and in the investigation of arbitratry compounds. One could rapidly investigate thin-film deposition of nearly any compound regardless of the complexity of the crystal chemistry.
