This item is printed on demand - it takes 3-4 days longer - Neuware -In the last decades, there has been a new trend towards looking at language from a 'functional' point of view, and the advent of looking at the 'functional' side of grammar led to more awareness of language analysis and language interpretation. The traditional view of language as a set of rules has been extensively neglected by many linguists like Halliday, Martin, Christie, and others, and has been substituted by original practices and dynamic functions. However, the objectives of both grammar and discourse analysis can be explicitly characterised as to ' construct a grammar for purposes of text analysis: one that makes it possible to say sensible and useful things about any text, spoken or written, in modern English.' (Halliday 1994:xv). This reasearch is an attempt to answer these issues and provide a prattical analysis of some texts in terms of the metafunctions of grammar. 52 pp. Englisch.

One of the main contributors to elevated levels of natural background radiation is the technology enhanced Naturally Occurring Radioactive Materials (NORM). Oil and gas exploration and processing activities usually accompanied with large quantities of NORM. Oil and gas NORM is found in piping, wellheads piping, storage tanks and other installations. Awali and Riffa Views gated communities in the Kingdom of Bahrain are located in areas of extensive oil and gas industrial activities. Oil wellheads and oil pipelines are located in close approximation to the residents' accommodation. The aim of this book is to assess the radiation levels in oil and gas fields and their hosting communities in the Kingdom of Bahrain. Performing radiological impact assessments facilitate the concerns to have a better control on radiation pollution if the location of risk is known. 68 pp. Englisch.

The rules governing resort to force form a central element within international law. This book, therefore, is devoted to deal with jus ad bellum. First, the regulation of war in the early days of international law until 1945 is discussed. Then, it focuses on the legality of the use of force in the post-Charter era. It begins by discussing the prohibition of the use of force under the UN Charter. After that, it analyses the justifications for the use of force in terms of self-defence and authorised force by the Security Council. It also argues whether the customary right of anticipatory self-defence was abolished by the Charter and whether such a right has been revived in the period after 1945. Next, this book explores many issues that are the subject of ongoing and longstanding debate such as the Legitimacy of humanitarian intervention and the 'protection of nationals' doctrine. Finally, it determines the consequences of an illegal use of force. This book will be of great interest to researchers and students of international law, conflict and Security Studies in general. 88 pp. Englisch.

Connaissant tous les paramètres du système, la géométrie du domaine, les conditions aux limites et initiales, les coefficients dans les équations, le modèle à résoudre constitue un problème direct. Par contre si certains paramètres dans l'équation sont inconnus et si on peut déterminer ces paramètres à partir de données expérimentales ou à partir des valeurs à l'instant final dans un problème donné, l'identification d'un tel paramètre constitue un problème inverse. Un problème inverse est donc un problème dans lequel on cherche à déterminer les causes d'un phénomène à partir des observations expérimentales de ses effets. Un exemple type est celui de la sismologie pour lequel la détermination de l'origine d'un séisme se fait à partir des mesures des amplitudes faites sur la surface de la terre . Une des sources importantes des problèmes inverses est l'hydrogéologie, ou l'étude des nappes phréatiques, le le contrôle des polluants dans les nappes d'eau souterraine est l'un des problèmes d'actualité. 92 pp. Englisch.

The percentage inhibition increased with the increase of the concentration of the inhibitor. At a concentration of 2.0 g/L, the percentage inhibition reached about 87% at room temperature and 80% at 303 K. The percentage inhibition decreased with the increase of temperature. The thermodynamic parameters for the adsorption of this inhibitor on the metal surface were calculated using the Temkin adsorption isotherm. The aqueous Neem leaves extract was found to be an excellent potential corrosion inhibitor because of the high content of tannin content as well as the presence of a series of complex triterpene glycosides. 52 pp. Englisch.

This operator, like the others of Dunkl type, plays an important role in the description, in quantum mechanics, of the exactly resolvable models of Calogero-Morse-Sutherland. Its eigenfunction admits a Laplace integral representation whose kernel allows us to define the Jacobi-Dunkl transmutation operators that are shown to be positive. Then, for the Jacobi-Dunkl transform, we formulate inversion formulas and a Paley-Wiener theorem. Using the properties of the transmutation operators and the estimates of the heat kernel, we obtain a version of the Cowling-Price and Hardy theorems for the Jacobi-Dunkl transform. In the case of a bounded interval, we show that the eigenfunction of the Jacobi-Dunkl operator, equal to 1 at zero, is a trigonometric polynomial, related to the Jacobi polynomials. Then, we give a Laplace integral representation of this function called Jacobi-Dunkl polynomial. Finally, we study the harmonic analysis associated with this operator. 88 pp. Englisch.

The first essay suggests that the axiomatic emphasis of Hume's philosophic enterprise, as it is formulated in his first and main book A Treatise of Human Nature (1739), is that thought should first return to common sense, before (perhaps) venturing into any further realms of conceptualization. He insists that no philosophic inquiry will ever get us beyond the everyday experiences or furnish us with norms of behaviour other than those which are the outcome of reflecting on our ordinary modes and matters of life. In The Second essay Macmurray's suggestion, in Freedom in the Modern World, that 'we shall never solve our economic troubles except in solving the dilemma in our spiritual life which produces them' is discussed in relation to his characterization of freedom as the capacity for friendship. The third essay simply ventures to present a phenomenological characterization of what Sartre's Nausea and Camus' Absurd signify and how they do existentially differ. 64 pp. Englisch.

However this water quality is objectionable. Typical problems regarding the use of surface water are presence of suspended solids, colloidal particles, turbidity, and agriculture runoff. Roughing filters are one of the economical solutions to remove the suspended particles from the surface water. Lab scale setup of three roughing filters was designed and operated using synthetic raw water of high turbidity, having turbidity up to 200 NTU. Turbidity of the influent water was maintained by intermittent manual mixing and flow rate of the influent water was maintained by using the pipe and valve assembly. Three filters were have different size of media and were operated at three different loading rates i-e., 1.1 m/hr, 1.5 m/hr and 1.9 m/hr. It is concluded from this study that 1.5 m/hr hydraulic loading rate and 8-12 mm media size is most appropriate to operate the roughing filter. Hypothesis of the study is that 'rapid filtration theory can be applied to roughing filters. It is concluded from this study that rapid filtration theory can be applied to roughing filtration. 128 pp. Englisch.

When the signal bandwidth is increased, memory effects are appeared and are not negligible. These distortions and interferences reduce extremely the performance of the transmitter system. In order to transmit the high-quality signal and have a system with high efficiency, the solution is compensating the nonlinearity of the power amplifier by the linearization methods. There are several linearization techniques to improve the efficiency power amplifier. Some of these methods include feedback, feedforward, and predistortion. One of the advantages of pre-distortion linearization method compared to other methods can be noted to the low cost and implementation complexity reduction. Generating the nonlinearity distortion prior to the power amplifier is called the predistortion (PD) such that the generated nonlinearity can remove the inherent nonlinearity of the power amplifier. The predistortion can be utilized in the baseband domain and then be implemented by digital signal processing (DSP) methods. 108 pp. Englisch.

A high brightness electron gun with small emittance and high average beam current is one of the key goals in current technological developments. RF electron guns have the ability to reduce emittance growth due to the space-charge effects. Among RF guns, thermionic guns are quite attractive because of their simple configuration with no high voltage stage or complicated laser systems. In addition, the high acceleration reached in the gun cavity (up to 100 MV/m) can easily compress the bunch lengths to have sufficient peak current for FEL driving. On the other hand, Back Bombardment (BB) effect limits the wide usage of Thermionic RF guns worldwide. In this book, BB phenomena, associated effects and method of mitigations are presented. Numerical Model for simulating the effect of back bombardment in thermionic RF gun is used to discus the phenomenon. 104 pp. Englisch.
