Polymer Degradation and Stabilization
Author: W. L. Hawkins
Publisher: Springer Science & Business Media
ISBN: 3642693768
Category : Technology & Engineering
Languages : en
Pages : 129
Book Description
The development of polymers as an important class of material was inhibited at the first by the premature failure of these versatile compounds in many applications. The deterioration of important properties of both natural and synthetic polymers is the result of irreversible changes in composition and structure of polymers molecules. As a result of these reactions, mechanical, electrical and/or aesthetic properties are degraded beyond acceptable limits. It is now generally recognized that stabilization against degradation is necessary if the useful life of polymers is to be extended sufficiently to meet design requirements for long-term applications. Polymers degrade by a wide variety of mechanisms, several of which affect all polymers through to varying degree. This monograph will concentrate on those degradation mechanisms which result from reactions of polymers with oxygen in its various forms and which are accelerated by heat and/or radiation. Those stabilization mechanisms are discussed which are based on an understanding of degradation reaction mechanisms that are reasonably well established. The stabilization of polymers is still undergoing a transition from an art to a science as mechanisms of degradation become more fully developed. A scientific approach to stabilization can only be approached when there is an understanding of the reactions that lead to degradation. Stabilization against biodegradation and burning will not be discussed since there is not a clear understanding of how polymers degrade under these conditions.

Improving Capacity for Stabilization and Reconstruction Operations
Author: Nora Bensahel
Publisher: Rand Corporation
ISBN: 0833046985
Category : History
Languages : en
Pages : 105
Book Description
U.S. experiences in Iraq and Afghanistan have demonstrated that improving U.S. capacity for stabilization and reconstruction operations is critical to national security. To help craft a way ahead, the authors provide an overview of the requirements posed by stabilization and reconstruction operations and recommend ways to improve U.S. capacity to meet these needs.

The Limits to Travel
Author: David Metz
Publisher: Routledge
ISBN: 1136553282
Category : Transportation
Languages : en
Pages : 178
Book Description
As affluence grows, it gets easier to travel faster and further. But research shows that, despite this, the average travel time in all societies remains steady at roughly an hour a day. The implication is that people are choosing to increase the distance they regularly travel, rather than opting for shorter journey times. While this clearly offers advantages in terms of reaching more desirable locations, the disadvantages are numerous - not least that of anthropogenic climate change, to which transport is the fastest growing contributor. However, the stability of travel time does not form part of the present conceptual framework of transport policy makers and professionals - consequently, misconceived decisions lead to unintended outcomes. In this intriguing book, David Metz examines the inadequacies inherent in the current thinking, along with the resulting problems, such as pollution, congestion and noise. He highlights the impact of the rapid increase in car use in China and India, and explores the general travel experience, public vs. private transport, and transport technology. In considering to what extent travel could be avoided, he arrives at a new paradigm to underpin sustainable transport policies, based on the fundamental characteristics of human mobility and focusing on quality, not quantity, of travel.
