Strain-Hardening Fibre-Reinforced Cement-Based Composites (SHCC) were named after their ability to resist increased tensile force after crack formation, over a significant tensile deformation range. The increased resistance is achieved through effective crack bridging by fibres, across multiple cracks of widths in the micro-range. Whether these small crack widths are maintained under sustained, cyclic or other load paths, and whether the crack width limitation translates into durability through retardation of ingress of moisture, gas and other deleterious matter, are scrutinized in this book by evaluation of test results from several laboratories internationally. The durability of SHCC under mechanical, chemical, thermal and combined actions is considered, both for the composite and the fibre types typically used in SHCC. The compilation of this state-of-the-art report has been an activity of the RILEM TC 208-HFC, Subcommittee 2: Durability, during the committee life 2005-2009.

Self-healing materials are man-made materials which have the built-in capability to repair damage. Failure in materials is often caused by the occurrence of small microcracks throughout the material. In self-healing materials phenomena are triggered to counteract these microcracks. These processes are ideally triggered by the occurrence of damage itself. Thus far, the self-healing capacity of cement-based materials has been considered as something "extra". This could be called passive self-healing, since it was not a designed feature of the material, but an inherent property of it. Centuries-old buildings have been said to have survived these centuries because of the inherent self-healing capacity of the binders used for cementing building blocks together. In this State-of-the-Art Report a closer look is taken at self-healing phenomena in cement-based materials. It is shown what options are available to design for this effect rather than have it occur as a "coincidental extra".

African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa can feed itself in a generation and can help contribute to global food security. To achieve this Africa has to define agriculture as a force in economic growth by advancing scientific and technological research, investing in infrastructure, fostering higher technical training, and creating regional markets.

This book describes the enormous depth of work carried out since the early 1970s on the Messina Strait Bridge, up to the recent award of the detailed design and construction contract. This important work has included extensive studies, concepts and design developments, with far reaching applications, which have all confirmed the feasibility of this huge endeavour and have led to the optimisation of costs and expected performance levels. Attention is focused not only on the design itself, but also on the context for the project (e.g. historical, geological, seismo-tectonic and wind conditions; structural and mechanical properties; project management and financial aspects; and environmental considerations), and on the great challenges involved. Thus, considering the innovations and specific solutions adopted in overcoming the challenges presented by constructing a world record span of 3,300 metres at this site, it becomes clear how the Messina Strait Crossing will take its place as a masterpiece in bridge engineering history. This book will be of interest to bridge and structural engineers, geotechnical and wind engineers, mechanical and earthquake engineers, graduate students in all these areas and all others with a broad interest in bridge design and engineering.

The International Political Thought Of Carl Schmitt

Presenting the first critical analysis of Carl Schmitt's The Nomos of the Earth and how it relates to the epochal changes in the international system that have risen from the collapse of the ‘Westphalian’ international order. There is an emerging recognition in political theory circles that core issues, such as order, social justice, rights, need to be studied in their global context. Schmitt’s international political thought provides a stepping stone in these related paths, offering an alternative history of international relations, of the genesis, achievements and demise of the ‘Westphalian system.’ Writing at a time when he believed that the spatial, political and legal order—the nomos of the earth—had collapsed, he highlighted the advent of the modern state as the vehicle of secularization, tracing how this interstate order was able to limit and ‘rationalize and humanize’ war. Providing a large number of case studies including: global terrorism, humanitarian intervention and US hegemony, this book will give further impetus to, and expand, the nascent debate on the significance of Schmitt’s legal and political thought for international politics. The International Political Thought of Carl Schmitt will be of interest to students and scholars of international relations, law and history.

The revised 13th edition of the essential reference for the prescribing of drugs for patients with mental health disorders The revised and updated 13th edition of The Maudsley Prescribing Guidelines in Psychiatry provides up-to-date information, expert guidance on prescribing practice in mental health, including drug choice, treatment of adverse effects and how to augment or switch medications. The text covers a wide range of topics including pharmacological interventions for schizophrenia, bipolar disorder, depression and anxiety, and many other less common conditions. There is advice on prescribing in children and adolescents, in substance misuse and in special patient groups. This world-renowned guide has been written in concise terms by an expert team of psychiatrists and specialist pharmacists. The Guidelines help with complex prescribing problems and include information on prescribing psychotropic medications outside their licensed indications as well as potential interactions with other medications and substances such as alcohol, tobacco and caffeine. In addition, each of the book’s 165 sections features a full reference list so that evidence on which guidance is based can be readily accessed. This important text: Is the world’s leading clinical resource for evidence-based prescribing in day-to-day clinical practice and for formulating prescribing policy Includes referenced information on topics such as transferring from one medication to another, prescribing psychotropic medications during pregnancy or breastfeeding, and treating patients with comorbid physical conditions, including impaired renal or hepatic function. Presents guidance on complex clinical problems that may not be encountered routinely Written for psychiatrists, neuropharmacologists, pharmacists and clinical psychologists as well as nurses and medical trainees, The Maudsley Prescribing Guidelines in Psychiatry are the established reference source for ensuring the safe and effective use of medications for patients presenting with mental health problems.
