Tobacco or Health?


Book Description

"Science tends to generalize, and generaliza tions mean simplifications . . . . And generaliza tions are also more satisfying to the mind than details. Of course, details and generalizations must be in proper balance: Generalizations can be reached only from details, while it is the generalization which gives value and interest to the detail:' . . . (A. Szent-Gyorgy, Science 1964) The first edition of this book, published in German as Tabak abhiingigkeit in 2001, was prompted by the fact that no single volume was available in Germany or elsewhere summarising the adverse repercussions of cigarette smoking on human health. As far as my own research was able to ascertain, the last comprehensive work dealing with this subject was writ ten in Germany by the Dresden internist, F. Lickint, whose Tabak und Organismus was published in 1939 by the Hip pokrates-Verlag. All subsequent monographs in this field have tended to focus on detailed aspects, and there has been no shortage of publications on subjects such as how smokers can quit smoking, healthy eating for smokers etc. Friends and colleagues abroad have urged me to prepare an English language version of Tabakabhiingigkeit. In gladly complying with this suggestion, I have intentionally prepared an up dated and slightly enlarged new edition, taking account of the rapidly proliferating literature on the subject up to the start of 2002. The harmful sequelae of smoking are played down by politicians in many industrialised countries, including Ger many.




Manufactured Fibre Technology


Book Description

Manufactured Fibre Technology provides an accessible and comprehensive treatment of the chemical, physical and mechanical processes involved in the production of all important commodity manufactured fibres and most of the industrial fibres. The emphasis is on the fundamental principles and industrial aspects of production. Latest developments in manufactured fibres in terms of manufacturing processes, characteristics and their applications are also covered. Manufactured Fibre Technology is designed around twenty chapters with a balance of basic principles and production of specific fibre types. Newer and industrially relevant areas such as high speed spinning, production of speciality fibres (including microfibres), computer simulation of spinning, high performance fibres, spun-bonding and melt-blowing, and re-use of fibre waste are included. The structure, property and application areas of each fibre type are also discussed, thus providing a broad understanding of the subject. In addition, various aspects related to the testing and characterisation of fibres and polymers are reviewed. This book is an invaluable resource to students, lecturers, industrial technologists and researchers in this subject area.




New Horizons in Biotechnology


Book Description

The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.




Handbook of Tensile Properties of Textile and Technical Fibres


Book Description

Fibres usually experience tensile loads whether they are used for apparel or technical structures. Their form, which is long and fine, makes them some of the strongest materials available as well as very flexible. This book provides a concise and authoritative overview of tensile behaviour of a wide range of both natural and synthetic fibres used both in textiles and high performance materials.After preliminary chapters that introduce the reader to tensile properties, failure and testing of fibres, the book is split into two parts. Part one examines tensile properties and failure of natural fibres, such as cotton, hemp, wool and silk. Part two discusses the tensile properties and failure of synthetic fibres ranging from polyamide, polyester and polyethylene fibres to carbon fibres. Many chapters also provide a general background to the fibre, including the manufacture, microstructure, factors that affect tensile properties as well as methods to improve tensile failure.With its distinguished editor and array of international contributors, Handbook of tensile properties of textile and technical fibres is an important reference for fibre scientists, textile technologists and engineers, as well as those in academia. - Provides an overview of tensile behaviour of a wide range of both natural and synthetic fibres - Examines tensile characterisitics, tensile failure of textiles fibres and factors that affect tensile properties - Discusses mircostructures and each type of fibre from manufacture to finished product
