Book excerpt: This work consists of grouping together a three-phase Active Filter and an “uninterruptible power supply” into a single converter. This converter is then capable of reducing electromagnetic perturbations from the main AC supply and also of acting as a Backup Supply. It can adapt itself to any linear or non linear load, balanced or unbalanced. The converter is connected in parallel with the electric grid to impose optimal waveform currents on the main AC supply or to replace it. To implement the AF, the principal task has been to determine the optimal waveform of the supply currents. The objective is to obtain a maximal Power Factor. Since the supply voltages are distorted, the compensation method of "non active" power is used for reaching the maximal PF. The AF then supplies the non active power that the load absorbs. To mitigate failures from the main AC supply, a battery is connected to AF. A solution which allows minimization of the batteries encumbrance is proposed: it sets up a supplementary dc/dc converter which acts as buck/boost converter. The Active Filter – Backup Supply system works then in one of two modes according to the availability of the AC supply: 1) AC supply available, FACH (French name) mode: the AF compensates for the non active power and supplies the energy necessary for the charger (buck converter) to recharge the battery; 2) AC supply unavailable, OSE (French name) mode: the BS supplies sinusoidal voltages to load from the boost converter – battery group. The AF was validated by a 1.5kVA experimental model and the global AF-BS system by simulation.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Available in PDF, EPUB and Kindle. Book excerpt: The novel coronavirus SARS-CoV-2, which causes the disease known as COVID-19, has infected people in 212 countries so far and on every continent except Antarctica. Vast changes to our home lives, social interactions, government functioning and relations between countries have swept the world in a few months and are difficult to hold in one’s mind at one time. That is why a collaborative effort such as this edited, multidisciplinary collection is needed. This book confronts the vulnerabilities and interconnectedness made visible by the pandemic and its consequences, along with the legal, ethical and policy responses. These include vulnerabilities for people who have been harmed or will be harmed by the virus directly and those harmed by measures taken to slow its relentless march; vulnerabilities exposed in our institutions, governance and legal structures; and vulnerabilities in other countries and at the global level where persistent injustices harm us all. Hopefully, COVID-19 will forces us to deeply reflect on how we govern and our policy priorities; to focus preparedness, precaution, and recovery to include all, not just some. Published in English with some chapters in French.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1988, this book analyses the changes that took place in the economic organisation of the British construction industry throughout the 1970s and early 1980s, in particular considering its social and economic structure and examining the causes of its poor industrial record. Michael Ball describes how the major firms survived the economic slump between 1973 and 1982 - when construction workloads collapsed - by substantially restructuring their operations, relationships with clients, workforces and subcontractors. Detailed attention is paid to construction firms, the workers they employ, the influence of trade unionism and the role of other agencies in the building process. Reissued at a particularly challenging time for the British construction industry, this relevant and practical title will be of value to students and academics of economics and social change, as well as those on courses for construction professionals.

Book excerpt: Despite broad international recognition of the criminalization of illicit enrichment, it has not been universally accepted as an anti-corruption measure. Instead, criminalization of illicit enrichment continues to generate extensive debate and controversy. Against this background, this volume aims to provide an analysis of how illicit enrichment works, and attempts to shed light on any contributions that it has made to the fight against corruption and the recovery of stolen assets. Rather than delving into the theoretical and academic debates around illicit enrichment, this study focuses primarily on the analysis of current practice, case law, and existing literature to offer a new perspective to the on-going discussions. More specifically, the volume addresses the legal framework upon which the concept of illicit enrichment rests, and the resulting policy implications of that legal framework. It also focuses on illicit enrichment as an anti-corruption mechanism, from its roots as a response to the problems inherent to prosecutions involving corruption, to an examination of elements and inchoate offenses relating to illicit enrichment under international conventions. It examines illicit enrichment jurisprudence in the global context. An extensive survey was carried out to determine the countries where the offense exists, what form it takes, how often it is used, and for countries where it doesn't, what other measures are used in its place. The authors neither recommend nor oppose the adoption of illicit enrichment provisions, but rather aim to assist jurisdictions considering such steps by highlighting key questions that might arise during implementation, including how the offense is defined and enforced domestically by States. Similarly, the authors do not endorse nor criticize any practice carried out by States in the implementation of the criminalization of illicit enrichment. Ultimately, it is also hoped that this study provides a basis for further discussion amongst policy makers and practitioners, and fuels upcoming discussions by the Conference of State parties of the UNCAC and its Working Groups

Available in PDF, EPUB and Kindle. Book excerpt: A striking account of a colony for the mentally ill that forces a reconsideration of madness in society. What happens when the mentally ill are not isolated from society but are instead welcomed into it and invited to take a place in the fabric of the community? Are fear and rejection replaced by the understanding and sympathy often engendered by familiarity? Or are the barriers between the sane and the mad only strengthened? We have experienced a taste of this scenario in the U.S. in the last decade with the new emphasis on de-institutionalization, but Denise Jodelet takes us to an extraordinary community in France where the mentally ill have assumed a visible and prominent role for more than seventy years. The small French town of Ainay-le-Ch�teau and its environs are the site of a "family colony" for men, established in 1900. Here the patients ("lodgers") live with ordinary families ("foster parents"), hold jobs, and are free to move about the countryside. Jodelet's chronicle of daily life in the colony is made rich and vivid by extensive ethnographic material as she unravels a complex set of relationships, ultimately finding that while some of the barriers between the "other" and the larger society have been overcome, new ones have arisen in their place. This unique social experiment provides invaluable social and cultural insights, illuminating many fundamental issues in psychology, psychiatry, and sociology.

Available in PDF, EPUB and Kindle. Book excerpt: Are efforts to protect workers' rights compatible with the forces of globalization? How can minimum standards designed to protect labour rights be implemented in a world in which national labour law is more and more at the mercy of international forces beyond its control? And does it makeany difference if we see rights such as the right to freedom of association, to non-discrimination in the workplace, to freedom from child labour, and to safe and healthy working conditions in terms of international human rights law? Or are they more appropriately seen as 'principles' to bepromoted as and where appropriate?The contributors to this volume argue that international agreements and institutions are of central importance if labour rights are to be protected in a globalized economy. But the report cards they give to the World Trade Organization, the European Union, NAFTA, and the Free Trade Agreement of theAmericas are generally very critical. While there is a strong rhetorical commitment to labour rights, at least on the part of the US and the EU, the substance of what has been achieved to date is hardly impressive. The role of the International Labour Organization is central and the authorsexplore some of the options that are open to governments, civil society, and the labour movement in the years ahead.

This book was released on 1992 with total page 1088 pages. Available in PDF, EPUB and Kindle. Book excerpt: The result of years of work by scholars from all over the world, The UNESCO General History of Africa reflects how the different peoples of Africa view their civilizations and shows the historical relationships between the various parts of the continent. Historical connections with other continents demonstrate Africa's contribution to the development of human civilization. Each volume is lavishly illustrated and contains a comprehensive bibliography. This fifth volume of the acclaimed series covers the history of the continent from the beginning of the sixteenth century to the close of the eighteenth century in which two themes emerge: first, the continuing internal evolution of the states and cultures of Africa during this period second, the increasing involvement of Africa in external trade--with major but unforeseen consequences for the whole world. In North Africa, we see the Ottomans conquer Egypt. South of the Sahara, some of the larger, older states collapse, and new power bases emerge. Traditional religions continue to coexist with both Christianity (suffering setbacks) and Islam (in the ascendancy). Along the coast, particularly of West Africa, Europeans establish a trading network which, with the development of New World plantation agriculture, becomes the focus of the international slave trade. The immediate consequences of this trade for Africa are explored, and it is argued that the long-term global consequences include the foundation of the present world-economy with all its built-in inequalities.
