Nanostructured Materials by High-Pressure Severe Plastic Deformation
Recently, it was reported that nanostructured materials processed under high pressure by HPT and ECAP have an extraordinary combination of both high strength and high ductility, which are two desirable, but rarely co-existing properties. These findings indicate that high-pressure is a critical factor that can be employed to process nanostructured materials with superior mechanical, and possibly also physical, properties. It is the objective of this workshop to review our current knowledge, identify issues for future research, and discuss future directions on the processing and properties of nanostructured materials via SPD techniques, with a special emphasis on high-pressure effects.

Mitral valve diseases
The heart is a pump consisting of 4 chambers:2 atria and 2 ventricles and 4 valves one of them is mitral valve which is located betweenthe left atrium and the left ventricle and prevents the backward flow of blood.Ithas several unique features: Mitral annulus, two leaflets, the chordae tendineaeand papillary muscles. The mitral valve may become stenotic or may regurgitate. Regurgitation(or leakage of the valve): When the valve (s) do not close completely. Stenosis (or narrowing of the valve): When the valve (s) opening becomes narrowed. Mitral stenosis is categorized as mild, moderate or severe it is typically causedby (Rheumatic fever, A congenital heart, Calcium deposits .....) and it caused severalsymptoms such as: dyspnea, hemoptysis, fatigue, Chest pain and others Where as the Signs and symptoms of mitral valve regurgitation, can include: Abnormal heart sound, Shortness of breath, Heart palpitations, Fatigue, edma, Coughing.
Metal Matrix Composites
Metal matrix composites (MMCs) have become real engineering materials. MMCs have gone from "niche" materials to several high performance applications in aerospace, electronic packaging, automotive, and recreational products. This text focuses on the synergistic relationships among processing, microstructure, and properties of metal matrix composites. An introductory chapter is followed by a chapter each on reinforcements and common matrix materials. A chapter on the very important topic of processing of MMC is then presented. This is followed by a chapter on interfaces in MMCs, their characterization and techniques to obtain interfacial properties. Next there are chapters on monotonic mechanical and physical properties; followed by cyclic fatigue, creep, and wear resistance. We conclude with a chapter on applications of MMCs. The book is well-suited for upper level undergraduate students, graduate students, and as general source of reference on the subject for the professionals in the field.

Mechanical Behaviour of Engineering Materials : Metals, Ceramics, Polymers, and Composites
How do engineering materials deform when bearing mechanical loads? To answer this crucial question, the book bridges the gap between continuum mechanics and materials science. The different kinds of material deformation (elasticity, plasticity, fracture, creep, fatigue) are explained in detail. The book also discusses the physical processes occurring during the deformation of all classes of engineering materials (metals, ceramics, polymers, and composites) and shows how these materials can be strengthened to meet the design requirements. It provides the knowledge needed in selecting the appropriate engineering material for a certain design problem. The reader will thus learn how to critically employ design rules and thus to avoid failure of mechanical components.
Innovative Superhard Materials and Sustainable Coatings for Advanced Manufacturing ; Proceedings of the NATO Advanced Research Workshop on Innovative Superhard Materials and Sustainable Coating, Kiev, Ukraine,12 - 15 May 2004.
Modern industry imposes ever increasing requirements upon tools and tool materials as to the provision for performance under the conditions of high cutting speeds and dynamic loads as well as under intensive thermal and chemical interactions with workpiece materials. The industry demands a higher productivity in combination with the accuracy of geometry and dimensions of workpieces and quality of working surfaces of the machined pieces. These requirements are best met by the tool superhard materials (diamond and diamond-like cubic boron nitride). Ceramics based on silicon carbide, aluminum and boron oxides as well as on titanium, silicon and aluminum nitrides offer promise as tool materials. Tungsten-containing cemented carbides are still considered as suitable tool materials. Hi- hardness and high strength composites based on the above materials fit all the requirements imposed by machining jobs when manufacturing elements of machinery, in particular those operating under the extreme conditions of high temperatures and loads.

Editor Michael Feuerstein, himself a cancer survivor, and sixty other top scientist-practitioners analyze in depth how survivors meet and manage the challenges of life after cancer, and what clinicians, researchers, and public health systems can do to ease the transition.
Globalisation, Poverty and Conflict : A Critical 'Development' Reader
Is ‘development’ passé? Is it merely a by-product or a ‘trickle down’ effect of economic growth, spurred by globalisation? Will poverty simply diminish with increased global markets? This state-of-the-art critical ‘development’ reader deals with these and related questions. Globalisation, Poverty and Conflict examines the inter-relationships between globalisation, poverty and conflict. It complements current debates in the field of development studies and, in an era in which development fatigue seems to have become more profound than ever before, it brings the importance of development once again to the forefront. Achieving the Millennium Development Goals by 2015 is a concrete target which many governments have agreed to work towards.Whether these goals can be realised is another issue. Nonetheless, the Millennium Development Goals have brought more focused attention to development in the past few years and renewed debate about the relationships between the process of globalisation and widespread poverty and the emergence of violent conflicts. The authors in this edited volume discuss these inter-related and highly controversial topical elements of development in a number of chapters organised around three sets of issues: (1) globalisation, inequality and poverty; (2) governance, civil society and poverty; and (3) resource degradation, institutions and conflict. The contributions represent current thinking on (and practice of) development policy, poverty reduction, the need for multi-level democratic institutions, and the containing and prevention of conflicts. The authors confront the predominant mainstream ideas on ‘development’ and propose alternatives.

Fuzzy Logic Applications in Engineering Science
Fuzzy logic is a relatively new concept in science applications. Hitherto, fuzzy logic has been a conceptual process applied in the field of risk management. Its potential applicability is much wider than that, however, and its particular suitability for expanding our understanding of processes and information in science and engineering in our post-modern world is only just beginning to be appreciated.

Fatigue Science for Human Health
Fatigue is quite a familiar sensation, one that everyone is likely to have experienced. Its molecular and neural mechanisms have not yet been elucidated, however, probably because of the complicated nature of its causes. To provide a broad forum for discussion, the International Conference on Fatigue Science was organized, the first being held in 2002 in Sandhamn, Sweden, and the second in 2005 in Karuizawa, Japan. Subsequently it was decided that the papers presented at the two conferences should be collected and incorporated in this pioneering work, Fatigue Science for Human Health. The book summarizes fatigue researchers' achievements, explains the status of the research on fatigue, and presents perspectives on remedies for chronic fatigue and chronic fatigue syndrome. The result is an authoritative guide to recent progress in the molecular and neural mechanisms of fatigue and in the development of the ways to prevent and overcome fatigue and chronic fatigue.
