Available in PDF, EPUB and Kindle. Book excerpt: The part of this book covering pathogensis and modes of action begins with a chapter on the physicochemical properties of asbestos fibers and a chapter on the deposition and retention of fibers within the lung and their clearance. Some of the effects of asbestos can be reproduced in animal experiments, and the book includes a full review of the results from animal studies using various routes of administration of fibers. It is also generally accepted that the effects of fibers on pulmonary macrophages is central to all fiber-induced pathology, and the release of macrophage-associated inflammatory and immunological mediatros is dealt with in a further chapter. Examination of pathogenicity by cell culture is described, and areas covered include the role of free radicals and cellular mechanisms in producing genetic damage. The fiber-induced activation of some second messenger pathways is also described, with consideration of whether or not similar cellular mechanisms are responsible for all the clinical conditions associated with fiber exposure. Knowledge of the mechanisms involved should be valuable in the development of safe fibers and the prevention of human exposure to new materials that are dangerous as asbestos. The final chapters expound and resolve the conflicts in evidence, discuss the importance of fibers for human well-being and the possible health impact on nonmineral alternatives, and evaluate risks to the public
Download or read book Our Precious Metal written by Wilmot Godfrey James and published by New Africa Books. This book was released on 1992 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, the South African gold-mining industry, for decades dominated by a set of fixed and unchanging features, has undergone a transformation. Above all, it is in the area of labour relations that changes have been most rapid and profound. Faced with a crisis in traditional patterns of labour recruitment, the mines have been forced to revise their sourcing and recruiting strategies and in so doing have struck at the heart of the migrant labour system. At the same time, in an attempt to contain the crisis of control, the mines have, for the first time in a hundred years, permitted trade unions to organise among workers, and in consequence the National Union of Mineworkers (NUM) has emerged as a powerful force in the industry. These processes are the subject of Wilmot James's sociological and historical study of African mine workers, which provides the first major account in twenty years of labour in South Africa's gold industry. In his lucid and original analysis, based on material much of which was not previously available to researchers, Wilmot James traces the interlocking developments which have brought about a transformation in the gold industry, and relates these to wider processes of change in contemporary South African society.

This book was released on 2017-02-03 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: South Africa is facing the increasing challenge of acid mine drainage (AMD) whose genesis is the country’s mining history, which paid limited attention to post-mining mine site management. In mineral resource-rich Africa, this has emerged as one of the most daunting challenges of our time. South Africa has been bold in its approach to mitigating this problem, although the challenge is multi-faceted. On a positive note, substantial research has been conducted to confront the challenge. However, thus far, the research has been largely fragmented. This book builds on the work that has been done, but also provides a refreshing multi-disciplinary approach that is useful in addressing the AMD challenges that South Africa and the continent face. Whilst addressing the problem as a scientific and engineering challenge, the book also exposes the economic, policy and legal challenges involved in addressing the problem. The book concludes, quite uniquely, that AMD is an opportunity that can be used by South Africa and Africa to solve problems, such as acute water shortage, as well as mineral recovery operations.
