"This compilation will provide ready reference for potential toxicity of chemicals found in the workplace, and should be useful to occupational health physicians, industrial hygienists, toxicologists, and researchers." Alphabetical arrangement by substances. Entries include such details as molecular weight, Wiswesser Line Notation, synonyms, and reference from which data about toxicity derived. Miscellaneous appendixes, including one titled Aquatic toxicity. Bibliographic references.
AIDS epidemics continue to threaten the livelihoods of millions of people in sub-Saharan Africa. Three decades after the disease was first recognized, the annual death toll from AIDS exceeds that from wars, famine and floods combined. Yet despite millions of dollars of aid and research, there has previously been little detailed on-the-ground analysis of the multifaceted impacts on rural people. Filling that gap, this book brings together recent evidence of AIDS impacts on rural households, livelihoods, and agricultural practice in sub-Saharan Africa. There is particular emphasis on the role of women in affected households, and on the situation of children. The book is unique in presenting micro-level information collected by original empirical research in a range of African countries, and showing how well-grounded conclusions on trends, impacts and local responses can be applied to the design of HIV-responsive policies and programmes. AIDS impacts are more diverse than we previously thought, and local responses more varied - sometimes innovative, sometimes desperate. The book represents a major contribution to our understanding of the impacts of AIDS in the epidemic's heartland, and how these can be managed at different levels.
This volume presents the current state of knowledge on the osseous projectile weaponry that was produced by Pleistocene cultures across the globe. Through cross-cultural and temporal comparison of manufacturing methods, design, use methods, and associated technology, chapters in this volume identify and discuss differences and similarities between these Pleistocene cultures. The central research questions addressed in this volume include: (a) how did osseous weaponry technology develop and change through time and can these changes be tied to environmental and/or social influences?; (b) how did different Pleistocene cultures design and adapt their osseous weaponry technology to their environment as well as changes in that environment?; and (c) can we identify cultural interaction between neighboring groups through the analysis of osseous weapons technology — and if so — can we use these items to track the movement of peoples and/or ideas across the landscape? Through addressing these three central research questions, this volume creates an integrated understanding of osseous technology during a vital period in Modern Human cultural development which will be useful for students and advanced researchers alike.
The succulent and Nama-karoo form part of the arid south-western zone of Africa, a vast region of rugged landscapes and low treeless vegetation. Studies of this unique biome have yielded fascinating insights into the ecology of its flora and fauna. This book, originally published in 1999, is the first to synthesise these studies, presenting information on biogeographic patterns and life processes, form and function of animals and plants, foraging ecology, landscape-level dynamics and anthropogenic influences. Detailed analyses of the factors distinguishing the biota of the Karoo from that of other temperate deserts are given and generalisations about semi-arid ecosystems challenged. The ideas expounded, the ecological principles reviewed, and the results presented are relevant to all those working in the extensive arid and semi-arid regions of the world.
This book is a current, comprehensive and holistic assessment of the challenges facing a developing African state within the global context and is an up-to-the-minute review of the state of the South African environment.
