Seismic shaking can transform water-saturated sand into a liquid mass that will not support heavy loads such as buildings. This phenomenon, called liquefaction, causes much of the destruction associated with some earthquakes. Mexico City, for example, rests on the ancient lakebed of Lake Texcoco, which is a large basin filled with liquefiable sand and ground water. In the Mexico City earthquake of 1985, the wet sand beneath tall buildings liquefied and most of the 10,000 people who died were in buildings that collapsed as their foundations sank into liquefied sand.
Jets of sand sometimes erupt from the ground during an earthquake. These sand geysers or mud volcanoes occur when formations of soft, wet sand is liquefied and forcefully squeezed up through cracks in the ground. Despite these names, they have no relation to real geysers or volcanoes. Although they generally cause little damage, they are indications that more widespread liquefaction may have occurred or may be possible in the next earthquake.

Spurred by the healthcare building boom, evidence-based healthcare facility design is an important and growing trend in creating safe and nurturing patient-care environments. Hospital administrators are continually searching for proven, cost-effective strategies to do everything from enhancing patient safety and staff efficiency to improving the budget and bottom line.In this book, nurse and healthcare design consultant Cynthia McCullough gives readers the necessary knowledge, tools, and strategies to incorporate these design concepts into any design project-from the largest new healthcare facility construction to the smallest departmental renovation.Learn about:
* Working with design firms
* Aesthetics * Healing environments
* Family-centered care * Benchmarking
* Efficiency * Sustainability/green practices
* Move-in transition planning
* Future trends

Handbook of Rubber Bonding

398 pages
PDF 2.34 MB
Many books and papers have been published on the topic of adhesion of materials in general, but it is 40 years since a publication has been devoted solely to the subject of bonding of rubbers to various substrates.
The topics covered by this book have been selected to cover a wide range of interests, both in terms of products and applications.
The chapters in this volume have been written by experts in their fields, so the information can be regarded as the most up to date and state of the art knowledge on a particular subject.
Topics covered include:
* Techniques of Metal Preparation * Substrate Preparation * Adhesives for Rubber Bonding * Rubber to Metal Bonding using Co-agents * Rubber to Brass Bonding * Rubber to Fabric Bonding * Cobalt Promoted Metal Adhesion * Rubber to Thermoplastics Bonding * Rubber to Rubber Bonding * Cyanoacrylate Bonding * Waterborne Bonding Systems * Post Vulcanisation Bonding * Bonding of Silicone Rubber * Bonding Applications in power transmission belting * Tyre Cord adhesion * Failure in Rubber to Metal Bonding
Although there is some discussion of relevant theory in various sections of text, the emphasis in this volume has been to concentrate on the practicalities of bonding of rubbers, to themselves and substrates.
It is considered that this type of information is of immediate interest to the practising technologist dealing with shop floor problems on a daily basis.
This book will be ideal for those who are just about to embark upon the practice of bonding rubbers but it will be equally useful to those practitioners already involved in this field.

Computational Fluid Dynamics: A Practical Approach
Publisher: Butterworth
472 pages
October 1, 2007
ISBN: 0750685638
DJVU 7 MB
A senior level undergraduate and graduate textbook for a wide audience of engineering students taking a first course in CFD or Computer Aided Engineering. Fully course matched, with the most extensive and rigorous pedagogy and features of any book in the field. The first book in the field aimed at CFD users rather than developers.
· The only course text available that is specifically designed to give an applications lead, software oriented approach to understanding and using CFD. This is coupled with a complete grounding in the necessary mathematical principles of CFD.
· Unlike existing books this has not been written with the needs of advanced students who are expected to develop their own CFD code in mind. The widespread availability of commercial software enables this book to meet the needs of beginner CFD students who use commercial software.

This volume presents the proceedings of the International Conference on The Science and Engineering of Recycling for Environmental Protection (WASCON 2000), of which a number of themes have been identified. All are inter-related and inter-dependent in so far as potential users of secondary, recovered or recycled material have to be assured that the material is environmentally safe and stable. It is the environmental challenge that forms a leading theme for the conference, and the themes of quality assurance and quality control support this aspect. In terms of use of 'recovered' materials, science and engineering play important and inter-dependent roles and this is reflected in themes which form the very core of the conference. Of no less importance is control of land contamination and how we propose to model for the long term impact of our aims

Structural Monitoring with Fiber Optic Technology
Publisher: Academic Press
716 pages
March 12, 2001
ISBN 0124874304
PDF 17 MB
This book is the first to address the field of structurally integrated fiber optic sensors. Fiber optic sensors embedded within materials and systems are able to measure a variety of parameters (i.e. temperature, vibration, deformation, strain, etc.) that allows for real time non-destructive evaluation. Examples include the following: monitoring structural fatigue in aging aircraft or loads in bridge structures. In more advanced applications, fiber optic sensors control actuators that allow materials to adapt to their environment. This gives rise to the names, "smart," "intelligent," and/or "adaptive" materials or structures.
Structural Monitoring with Fiber Optic Technology is the firs single author book on the new field of fiber optic structural sensing. As such it provides: coverage of the fundamentals of the technology, a coherent and systematic discussion on the most important aspects of the subject, a broad view of the subject, while retaining a degree of focus on those advances most significant in terms of their future potential, particularly in regard to broad implementation of the technology. The book provides an introduction to the relevant value to structural monitoring. It also highlights the advantages of fiber optic based sensors over conventional electrical measurement technology.
