This book covers a wide range of processes which govern the properties and evolution of the deep continental crust. The response of rocks to conditions of deep crustal metamorphism and the onset of melting is a fundamental part of large-scale geological history which researchers have only recently begun to understand in any detail. This book aims not only to document recent research on this important area of geology but also to explain current methods of investigation and the interpretation of results. The main aspects of petrology of high-grade, regional metamorphic rocks are covered as well as melting and fluid transport within the Earth's crust. Chapters on theoretical framework and relevant experiments are complemented by others on key regions illustrating high-grade metamorphism. These include Sri Lanka and central Australia, which are now being studied intensively for the first time, and the classic ground of the Adirondack Mountains in New York and the Lewisian of Scotland. The study of these areas is based largely on petrological lines but tectonic settings are also considered.As a guide to recent developments, the book is considered essential reading for research workers and students of geology and should provide an invaluable reference work for lecturers and a useful introduction for non-specialist geologists.

A collective biography of the veterans of the battle of El Santuario (1829), this book uses the untold stories of ordinary lives to examine the history of the imperial conflicts that shaped politics and society in Colombia and Venezuela after independence from colonial rule.

The Cultural Work of Corporations argues that corporate culture - the values, customs, and conventions of a business organization - has altered how workers conduct themselves both inside and outside the workplace.

The recent outbreaks of E.coli and BSE have ensured that the issue of meat safety has never had such a high profile. Meanwhile HACCP has become the preferred tool for the management of microbiological safety. Against a background of consumer and regulatory pressure, the effective implementation of HACCP systems is critical. Written by leading experts in the field, HACCP in the meat industry provides an authoritative guide to making HACCP systems work effectively.This book examines the HACCP in the meat industry across the supply chain, from rearing through to primary and secondary processing.

Microbiological risk assessment (MRA) is one of the most important recent developments in food safety management. Adopted by Codex Alimentarius and many other international bodies, it provides a structured way of identifying and assessing microbiological risks in food. Edited by two leading authorities, and with contributions by international experts in the field, Microbiological risk assessment provides a detailed coverage of the key steps in MRA and how it can be used to improve food safety.The book begins by placing MRA within the broader context of the evolution of international food safety standards.Part one introduces the key steps in MRA methodology. A series of chapters discusses each step, starting with hazard identification and characterisation before going on to consider exposure assessment and risk characterisation. Given its importance, risk communication is also covered. Part two then considers how MRA can be implemented in practice. There are chapters on implementing the results of a microbiological risk assessment and on the qualitative and quantitative tools available in carrying out a MRA. It also discusses the relationship of MRA to the use of microbiological criteria and another key tool in food safety management, Hazard Analysis and Critical Control Point (HACCP) systems.With its authoritative coverage of both principles and key issues in implementation, Microbiological risk assessment in food processing is a standard work on one of the most important aspects of food safety management.Provides a detailed coverage of the key steps in microbiological risk assessment (MRA) and how it can be used to improve food safetyPlaces MRA within the broader context of the evolution of international food safety standardsIntroduces the key steps in MRA methodology, considers exposure assessment and risk characterisation, and covers risk communication

The past twenty years have seen dramatic changes in the processing, storage, distribution and packaging of meat and meat products, and consequently the important areas of its microbiology have also changed. These changes in product ranges have been largely prompted by the producers' desire for economies of scale in production and the con­ sumers' desire for a wide variety of meat products to be readily available. The purpose of this book is to present a collection of chapters written by specialists on particular aspects of meat microbiology. I hope the structure will present the reader with chapters which, read singly, present a clear account of one aspect, but taken together present a practical and coherent survey of meat microbiology. The chapters may be roughly divided into: (i) Commodity chapters - carcass meat, poultry meat, processed meat, cured meat and by-products. (ii) Quality assurance chapters - bacteria of public health significance, microbiological examination of meat, sampling and limits. The commodity chapters set out the characteristic microbiology of product groups in some detail and provide a practical guide to micro­ biological considerations in the production of particular types of pro­ duct. Whilst the content of these chapters is particularly useful to the is often difficult to working microbiologist, information of this nature gather, if it is considered to be commercially valuable, so that the authors have done specially useful tasks in assembling comprehensive data concerning their topics.

This second volume in the new series produced by the Mineralogical Society is concerned with the study of rocks from the deep continental crust. It is, we hope, timely to summarize recent petrological advances contributing to this field of active interest. Based mainly on review papers read at a conference, the chapters have subsequently been revised and expanded, while the editors have produced an introductory overview as Chapter 1. The conference was the Winter Meeting of the Mineralogical Society on 15 December 1988, at wh ich Prof. R. C. Newton delivered the 20th Hallimond Lecture of the Society (which forms the basis of Ch. 7). The editors are grateful to all who contrib­ uted to the smooth running of the meeting at Kingston Polytechnic, and in the ensuing preparation of the volume: in particular, we sincerely thank all of the following for their labours as referees: A.
