Polymers in Agriculture and Horticulture

By: Roger P. Brown

Polymers have been used in agriculture and horticulture since the middle of the last century. There is a tremendous potential for using polymers in agriculture and our fields and garden would look very different if we did not use polymers in them. This review traces the history of polymer use, discusses the markets for polymers in these applications, and describes in detail the different types of polymers that can be used and their specific applications. An additional indexed section containing several hundred abstracts from the Polymer Library gives useful references for further reading.

Rubber Product Failure

Rubber Product Failure

By: Roger P. Brown

Rubber components are used in many demanding applications, from tyres and seals to gloves and medical devices, and failure can be catastrophic. This review of Rubber Product Failure outlines and illustrates the common causes of failure, while addressing ways of avoiding it. There has been increasing pressure to improve performance so that rubbers can be used at higher temperatures and in harsher environments. For example, the under-the-bonnet temperature has increased in some vehicles and new medical devices require longer lifetimes in potentially degrading biological fluids. The expectations of tyre performance in particular are increasing, and retreads have been in the spotlight for failures. The definition of failure depends on the application. For example, a racing car engine seal that lasts for one race may be acceptable, but in a normal car a life span of 10 years is more reasonable. If appearance is critical as in surface coatings and paints, then discolouration is failure, whilst in seals leakage is not acceptable. Each rubber product must be fit for the use specified by the consumer. Failure analysis is critical to product improvement. the cause of the problem can be much harder to find. It can range from a design fault to poor material selection, to processing problems, to manufacturing errors such as poor dimensional tolerances, to poor installation, product abuse and unexpected service conditions. The rubber technologist must become a detective, gathering evidence, understanding the material type and using deductive reasoning. Testing and analysis of failed materials and components add to the information available for failure analysis. For example, stored aged tyres appeared superficially to be alright for use, but on drum testing small cracks grew more quickly than in new tyres leading to rapid failure in service. Quality control procedures such as product inspection, testing and material quality checks can help to reach 100 percent reliability. In critical applications such as electricians' gloves for high voltage working, gloves are inspected before each use, while engine seals may be routinely replaced before the expected lifetime to avoid problems. in the literature is not high. However, several reviews have been written on specific products and references can be found at the end of this review. Around 400 abstracts from papers in the Polymer Library are included with an index. Subjects covered include tyre wear and failure, seals, engine components, rubber bonding failure, rubber failure due to chloramine in water, tank treads, gloves and condoms, medical devices and EPDM roofing membranes.

St. Francis of Assisi and Nature

Tradition and Innovation in Western Christian Attitudes Toward the Environment

By: Roger D. Sorrell

This book examines one aspect of the life and thought of Francis of Assisi, founder of the Franciscan monastic order. Contemporary interest in Francis has focused on his attitude toward nature. Sorrell argues persuasively that Francis' ideas can only be properly understood in their thirteenth-century context. Through close analysis of Francis' writings, Sorrell shows that many of Francis' beliefs concerning the proper relation of man to the natural world have their antecedents in scripture and in the medieval monastic tradition. Other Franciscan ideas and practices, however, appear entirely original; his nature mysticism, his concept of familial relationships with created things, his extension of Christian almsgiving to creatures. Sorrell insists, however, that only by seeing Francis in terms of the Western traditions in which he arose can we appreciate the true originality of this extraordinary figure, and the relevance of his thought to modern environmental concerns.

Long-Term and Accelerated Ageing Tests on Rubbers

By: Roger P. Brown,M. J. Forrest

The properties of rubbers are subject to change as a result of ageing, ultimately to the point where the material is no longer capable of fulfilling its function. After a brief introduction to the main environmental and mechanical factors affecting performance, this review focuses on the thermo-oxidative ageing of rubber. It considers the methods of, and the published results from, both natural and accelerated tests. A major section of the report is devoted to exposure and test techniques with discussion of the methods of physical and chemical analysis. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

Early Medieval Europe, 300-1000

By: Roger Collins

In this classic textbook history of early medieval Europe, Roger Collins provides a succinct account of the centuries during which Europe changed from being an abstract geographical expression to a new culturally coherent, if politically divided, entity. This comprehensive new edition explores key topics such as the fall of the Roman Empire, the rise of both Christianity and Islam, the Vikings, and the expansion of Latin Christian culture into eastern Europe. Clear and insightful, this is an invaluable guide to an important era in the history of both Europe and the wider world. This is an ideal companion for students of History or European Studies taking modules on Early Medieval Europe or Europe in Late Antiquity. In addition, this is a useful reference work for postgraduate students, scholars and teachers of early medieval Europe. New to this Edition: - Fully updated, augmented and revised to take account of the latest scholarship and research on all aspects of the period it covers - Greater emphasis given to social and economic considerations, the peripheries of Europe, the rise and impact of Islam, art, architecture, books and the spread of learning - Extensively rewritten to make it more accessible for students

Cortical Oscillations in Health and Disease

Cortical Oscillations in Health and Disease

By: Roger D. Traub,Miles A. Whittington

This book first reviews the case that brain oscillations not only are important for cognition, as long suspected, but also play a part in the expression of signs and symptoms of neuropsychiatric disorders. The cellular mechanisms of many of the clinically relevant oscillations have been studied by the authors and their colleagues, using in vitro slice methods as well as detailed computer simulations. A surprising insight is that gap junctions between principal neurons play an absolutely critical role in so many types of oscillation in neuronal populations; oscillations are not just the result of properties of individual neurons and their synaptic connections. Furthermore, the way in which gap junctions produce oscillations in the cortex is novel, involving as it does global properties of networks, rather than just the time constants of membrane currents. This insight has implications for therapeutics as well as for our understanding of normal brain functions.
