Most antioxidants isolated from higher plants are polyphenols, Phenolic compounds possess an effective inhibitory effect on cancer invasion and metastasis is also increasingly being reported in the scientific literature. Several polyphenols were tested on MCF7 cells, Only gallic acid and quercetin showed prominent inhibitory effects on MCF7. The cytotoxic properties of methoxy phenolic acid and it is derivatives, structurally related to the natural models (gallic acid, Combretastatin A4) have been tested on MCF-7 cells.
The purpose of this book is the correction of polyurethane by Vinyl tri methoxy silane. In this method, polyurethane was synthesized by the pre-polymer method, and polypropylene glycol, hex methylene disocyanate, and di-methyl propionic acid were used in the vicinity of the catalyst for this purpose. Then synthesized polyurethane is dispersed by double-distilled water and finally, vinyl monomers and versatic acid and vinyl acetate and vinyl trimethoxysilane along with polyurethane and with the emulsion polymerization method are converted to one vinyl-urethane hybrid co polymer modified with silane. The necessary tests among its thermal properties and stability were investigated. The obtained results indicate an increase and improvement of said properties.
Le pemphigus est une maladie bulleuse rare touchant la peau et les muqueuses. Le but de ce travail était d'étudier le profil épidémio-clinique, thérapeutique et évolutif du pemphigus en Tunisie Résultats : Nous avons colligé 60 cas (40 femmes et 20 hommes). L'âge moyen des patients était de 53±17 ans [20-88]. Parmi les 60 patients, 32 étaient atteints de pemphigus vulgaire (53,3%), 2 de pemphigus végétant (3,3%), 20 de pemphigus séborrhéique (33,3%), 4 de pemphigus foliacé (6,7%) et 2 de pemphigus herpétiforme (3,3%). La présence d'érosions de la muqueuse buccale initiale prolongeait la durée de cicatrisation de 17,92 à 29,31 jours en moyenne (p=0,047). Conclusion: Le pemphigus est une dermatose rare engageant le pronostic vital. Les complications sont fréquentes, liées à la maladie elle-même et à la corticothérapie. La plupart des incidents évolutifs (récidives, décès) surviennent dans les premiers mois d'évolution. L'atteinte de la muqueuse buccale initiale est identifiée comme facteur pronostique majeur influençant le pronostic à court terme mais aussi à long terme.
This book focuses on the visual cryptographic technique for encrypting of medical images before transmission or storage of them, This will make such images inaccessible by unauthorized personnel and also ensures confidentiality, The process made use of an encryption technique that is based on pixel shuffling and a secret key generated from the image. In this book, we are going to show how to split a secret image into three shares. All shares parts are necessary to reconstruct and reveal the secret, and the possession of either one, alone, is useless in determining the secret.

Human fingerprints are rich in details called minutiae, which can be used as identification marks for fingerprint verification. The goal of this paper is to develop a complete system for fingerprint verification through extracting and matching minutiae. To achieve good minutiae extraction in fingerprints with varying quality, preprocessing in form of image enhancement and binarization is first applied on fingerprints before they are evaluated. Many methods have been combined to build a minutia extractor and a minutia matcher. Minutia, extract all the details after optimization with the fingers of someone else's imprint. In this book, program is coded by MATLAB. For the program, some optimization at coding level and algorithm level are proposed to improve the performance of my fingerprint recognition system. These performance enhancements are shown by experiments conducted upon a variety of fingerprint images.

Fusible alloys are one of materials category which has attracted the attention of scientists and technologists around the world. Fusible alloys are usually eutectic mixtures of bismuth, lead, tin and cadmium. Fusible alloys melt at low temperature below 150 °C. The term fusible is used, when the alloy melts at low temperature, about the boiling water. In the past they known as Lipowitz's, Wood's, D'Arcet and Rose alloys and now they are known as Arconim's alloys. Wood's metal is the famous fusible alloy which contains 50% bismuth, 25% lead, 12.5% tin and 12.5% cadmium and melts at 70 °C. Fusible alloys are used in some fairly common items such as fire sprinkler systems in office buildings. Now other alloys having slightly different compositions in order to improve their peculiarities replaced them, because the field of applications of the mentioned alloys is extremely various. Fusible alloys are normally used in gravity casting but also lend themselves well to pressure casting and centrifugal casting methods. Bismuth alloys was primarily as laboratory interests before 1930. Bismuth alloys have very low melting temperature, low physical strength and used as solders for safe.

The book is a study is devoted to develop proposals & solutions can be applied to treat pollution problem produced by the textile industries, also to recycle water reducing the water resource shortage problem, the book also deals with the evaluation of the operational properties of the locally produced membrane system from the Laboratory of Research and Membrane Unit at the University of Technology / Baghdad (NF and UF membrane) to remove the dyes (disperse-Terasil Navy Blue, acidic- Red,reactive- Cibacron Navy C-B Blue) from the wastewater of AL- Kut textile factory which are widely used dyes in Wasit Governorate factories / Iraq. The book provides good understanding of the effectiveness of membrane systems (NF and UF) in rejecting these dyes under different conditions (pressure, temperature, Anti-scale acid). The experimental results showed that the removal ratio of both (dye &COD) using UF and NF membranes increases with increasing operational pressure, and also the type of reactive dye is the most intense and concentrated.
This study aims at examining the role that knowledge ¿ as a multi- dimensional aspect- plays in economic growth in a sample of Arab countries.For examining the impact of knowledge on economic growth, Cobb-Douglas production function was applied for some selected Arab countries by using cross-sectional time series analysis (panel data) for the period (1990-2011) for 15 Arab countries that are chosen according to data availability and KAM methodology. Different arrays of indicators have been used as proxies for knowledge economy aspects and they are regressed against the growth rate of output per worker in these countries by conducting different scenarios.
In this book, a numerical analysis technique based on nonlinear finite element method has been used to investigate the behaviour of high strength steel fibre reinforced concrete corbels under vertical loads. New material constitutive relationships for High Strength Steel Fibre Reinforced Concrete (HSSFRC) have been formulated. These proposed material constitutive relationships have been employed for formulating the material finite element models to study the behaviour of HSSFRC corbels.
Mineral and organic amendments are applied to the newly reclaimed soils in Egypt, especially sandy and calcareous sandy soils. T hese soils are very poor in organic matter and nutrients that are necessary for plants. So, the addition of organic amendments to these soil s does not only improve the physical and chemical properties, but also applying t hese organic materials has a positive impact on the forms of potassium, especially in calcareous sandy soils . This study aims to evaluate the application effects of a mineral fertilizer (K2SO4 ) and certain organic amendments (filter mud cake, sheep manure and poultry manure) on the Q/I relation of soil K and its parameters as well as forms of potassium of clay and calcareous sandy s oils. The effects of these amendments on some chemical properties of these soils and K uptake by some crops are also examined.
This work is confined to the preparation and characterization of acrylate polymeric additives. These additives were prepared by estrification of acrylic acid with different alcohols (decyl, 1- dodecyl, 1- tetradecyl and hexadecyl) and then copolymerization of the prepared esters with different moles of styrene. The molecular weights of the prepared copolymers were determined by GPC. The efficiencies of the prepared copolymers as viscosity index and flow improvers for base lube oil were studied. It was found that the best VI improver (D4) afforded value of VI equals to 177. On the other hand, the lowest temperature at which the lube oil doped with the most efficient additive (A1) retains its flow equals -22° C.

Despite its attractiveness, human rights are ambiguous and difficult term to define. The history of political theory is swollen with numerous speculations about what, specifically, are these rights and what they include. Is there any such thing called human rights? One might asks, do we really need to defend (and promote) human rights? I would argue that we need to promote and defend human rights for numerous important reasons the following are just some of them: (1). They are moral imperative. It is essential to realize that a man should not rest while his fellow men are still in slavery or do not have all of their necessary rights, (2).Political Requirement: They are political requirement for establishing a free, prosperous and civilized society. People cannot express their feelings and fulfill their demands without their rights being protected, and (3) They are the right thing to do. To put it simply, one could say that people must have their rights, not because they are human rights but because it is the right thing to do. If we do not do these then everything else is wrong.
Cowpea (Vigna unguiculatal) has an important role as a feeding crop. It can be used as green or dried seeds as a good diet for its high protein content. Cowpea is an important food and fodder legume in the sub-humid tropics of Africa. Estimated yield losses due to viral infection of cowpeas are between 10% and 100%. Over 140 viruses worldwide have been reported to attack cowpea and at least eleven of these viruses occur in Africa. Cowpea plants are often infected by more than one virus simultaneously with resultant yield losses.
Most orbital satellites today rely on solar panels to generate the necessary power for their normal operation. A spacecraft electrical power system (SEPS) generates stores, regulates, control, and distributes required electric power to whole spacecraft loads during the space mission life time. The (SEPS) consists of three main subsystems: primary power supply subsystem (PPSS), secondary power supply subsystem (SPSS), and control - regulation -distribution subsystem (CRDS). This search is focused on the designing of the PPSS. In this work the designed system is based on the conversion of PV energy into electric power via the (PV effect) using the solar cells. The main goal of the design procedure of the spacecraft (PPSS) is the verification of the optimal solution of generating the electric power required for the spacecraft loads, during the daylight of the orbit, and also able to charge the battery (SPSS) with the required power for the spacecraft loads, during the eclipse period of the orbit. the impacts of space radiation and the variation of the operating temperature of the cell are considered ,And it can compare between the several categories of PV cells.
Gasoline is a mixture of multiple components, gasoline quality plays leading role in most refineries; because it determines (60- 70) % of refineries profit. In this study factors affecting gasoline quality were verified, major gasoline quality parameters are identified and assessed to study the impact of gasoline quality on the engine performance, processing and environment. (640)samples of different Iraqi gasoline blends produced at al- Daura refinery are collected over (21) consecutive months. Four major quality parameters were investigated in this research according to Iraqi standard (2000) they are; Research Octane Number (RON), Reid Vapor Pressure (RVP), Sulphur content, and lead content. Statistical quality control tools are used to perform this assessment. A model of Quality Feedback System for Petroleum Products (QFSPP) is implemented to integrate and interlink gasoline production process activities with quality control and maintenance department and to enhance quality feedback system. This may change the control system at Al-Daura refinery to closed system, so as to improve and tighten up gasoline quality.
Muslims living outside their native countries suffer from different issues, especially those who reside in the European Union countries. The terrorist attacks, media and the misrepresentation of Islam and Muslims help increase Islamophobia, moreover; the impact of Islamophobia on Muslim women in the E.U. is larger because of their visibility.: what is meant by Islamophobia? What are the reasons behind its spread? What are the consequences of this phenomenon on Muslim women¿s behaviors, attitudes and situations in different life sectors? How is Islamophobia manifested in different levels? Finally, how both Muslims and Europeans think about it?

La reconnaissance des caractères fait l'objet de diverses applications de traitement d'images. En pratique, pour assurer la reconnaissance d¿un caractère, ce dernier est sujet d¿une étape de prétraitement, ensuite il est décrit par des primitives bien spécifiques, et finalement reconnu suite à la mise en correspondance de son descripteur avec ceux d¿une base prédéfinie. L¿extraction des primitives pertinentes et discriminantes se montre souvent la phase la plus complexe et critique lors de la conception d¿un système de reconnaissance car un mauvais choix des primitives influence négativement et nettement sur les résultats de la classification. A cet effet, nous nous sommes intéressés essentiellement à la proposition de deux nouveaux systèmes de reconnaissance basés sur les approches statistiques, structurelles et évolutionnistes (algorithme génétique et stratégie d¿évolution).

Where the most important objectives were determining the existing and maximum capacity that can be achieved from the site PV panels and determine the optimum sizing for electrolyser, fuel cell and hydrogen storage, by using data gathered.
Dans l¿industrie aéronautique et aérospatiale, le renforcement et la réparation des structures métalliques à l¿aide d¿un patch collé à base de matériau composite sont très reconnus comme techniques efficaces et rentables. De nombreux travaux se font actuellement pour améliorer la technique de la réparation des fissures par collage des patchs en composite. Ce travail va dans ce sens, il a pour objectif de déterminer par simulation numérique les performances de la nouvelle technique originalement proposée et développée au sein de Laboratoire Mécanique Physiques des Matériaux, c¿est la technique du double adhésif. L¿idée consiste à diviser la couche adhésive du simple patch en deux bandes avec différentes propriétés. La première bande est appliquée sur la région fissurée pour assurer le transfert des contraintes, la deuxième bande est employée au delà de cette région pour éviter l¿arrachement du patch.
As a comparative study, the research deals with two different types of economic news items the first items are written by native experts and the second are translated by non-native, non specialized journalists. The research in hand should focus on weak points in translating economic news items by non-specialized personnel. Hence, we can deal with three major features: Size: Reuters, which has its own coverage of economic news, produces in general long, detailed and elaborate news items, while TAP provides short and concise business news. Interest: Reuters as a global news agency is a key provider of international financial market data, while TAP is rather domestically oriented to cover economic news. Linguistic skills: linguistically speaking, it is unfair to compare non-native and native journalists. The comparison here is about craftsmanship; Reuters economic news items are produced by specialized economists (experts) while those provided by TAP are translated by non experts in the business field.
A travers notre étude, nous essayerons de jeter la lumière sur « Le thème de la guerre à travers le temps et l'espace dans L'Acacia de Claude Simon ». Notre tâche consistera à répondre à ces questions : Qu'est-ce que la guerre ? Pourquoi Claude Simon a-t-il accorde, dès ses premières oeuvres, une place aussi centrale au thème de la guerre ? Comment les deux guerres ont-elles été vues par Claude Simon ? Quel est l'impact des deux guerres mondiales selon notre lecture de L'Acacia ? Que signifie-t-il L'Acacia ? Qu'est-ce que cet acacia indique ou symbolise ? Nous allons recourir à l'approche psychocritique, thématique, comparative, paratextuelle, narratologique, bachelardienne et descriptive.
In recent years, organizations and various companies have started to join the knowledge process and new concepts such as knowledge work, work knowledge, knowledge management, and knowledge organizations, representative the intensification of this trend. "A considerable amount of knowledge management is common sense, but it's not common." To achieve the potential benefits of knowledge management, a systematic approach is required. The essentialities of this approach are explained in the following. Knowing that what you know (and what don't know). ¿ It is often supposed that this essential knowledge has been well understood, but for review and investigating about hypotheses, carrying out knowledge consideration is usually a good point for authenticating of the resources and knowledge usage. This should: Specifies the key areas of knowledge that require effective management, and evaluates the quality of information; ¿ Specifies the gaps in preparation of knowledge and discovers the repetitions; ¿ Specify the holders of key knowledge and reveal the vulnerable areas; ¿ Refers carefully to barriers at knowledge flows across the organization;
