ISO 15901-1:2005 Pore size distribution and porosity of solid materials by mercury porosimetry
ISO 15901-1:2005 describes a method for the evaluation of the pore size distribution and the specific surface in pores of solids by mercury porosimetry according to the method of Ritter and Drake. ISO 15901-1:2005 describes a comparative test, usually destructive due to mercury contamination, in which the volume of mercury penetrating a pore or void is determined as a function of an applied hydrostatic pressure, which can be related to a pore diameter.
Practical considerations presently limit the maximum applied absolute pressure to about 400 MPa (60 000 psia) corresponding to a minimum equivalent pore diameter of approximately 0,003 m. The maximum diameter is limited for samples having a significant depth due to the difference in hydrostatic head of mercury from the top to the bottom of the sample. For the most purposes, this limit can be regarded as 400 m. ISO 15901-1:2005 applies to inter-particle and intra-particle porosity but cannot distinguish between these porosities where they co-exist.
ISO 15901-1:2005 is suitable for the study of most non-wettable, by mercury, porous materials. Samples that amalgamate with mercury, such as certain metals, e.g. gold, aluminium, reduced copper, reduced nickel and silver, can be unsuitable for this technique or can require a preliminary passivation.

No More Muddling Through: Mastering Complex Projects in Engineering and Management
No More Muddling Through: Mastering Complex Projects in Engineering and Management
Rainer Züst, P. Troxler
Springer 2006
ISBN: 1402050178
185 pages PDF 3,7 MB
Sustainable solutions require the integration of social and ecological aspects in every planning and decision-making process. This means: analyse the real world and model the problem-situation as a system; understand the needs and objectives of the customers and clients; carefully develop alternative ideas and solutions, as well as evaluate concepts under multidimensional aspects/criteria. In this area Systems Engineering could offer a fruitful approach. Systems Engineering (SE) is a systematic way of thinking and a methodology to guide demanding problem-solving processes in the fields of management and engineering.
This book explains the most important principles and elements of Systems Engineering and three planning cases demonstrate the practical application.

History of the Modern Suspension Bridge: Solving the Dilemma between Economy and Stiffness
History of the Modern Suspension Bridge: Solving the Dilemma between Economy and Stiffness
Tadaki Kawada
# Paperback: 262 pages
# Publisher: ASCE Press (American Society of Civil Engineeers (April 30, 2010)
# Language: English

# ISBN-13: 978-0784410189
Product Description
When he was thinking about how to build a bridge across the River Tweed, Sir Samuel Brown stopped while observing a spiders web. Right at this time he discovered the suspension bridge."" Charles Bender, 1868. The English translation of Tadaki Kawadas landmark book traces the modern suspension bridge from its earliest appearance in Western civilization only 200 years ago to the enormous Akashi Kaikyo and Storebælt bridges completed at the end of the twentieth century. History of the Modern Suspension Bridge: Solving the Dilemma between Economy and Stiffness examines the conflicts, the bridge collapses, the colorful personalities, and the advancements that have shaped the development of the suspension bridge. From John Roebling and the Brooklyn Bridge to the legendary rivalry between Othmar Ammann and David Steinman, from the Tacoma Narrows Bridge collapse in 1940, which Kawada explores in depth, to the closing of Londons Millennium Bridge just three days after its opening, this book is a complete history of the modern suspension bridgewith a focus on the two essential factors in suspension bridge design, economy and stiffness, which are always in competition with one another. How do engineers reinforce the suspension bridge against the elements of wind and traffic, without sacrificing economy? History of the Modern Suspension Bridge: Solving the Dilemma between Economy and Stiffness will appeal to anyone interested in engineering history and suspension bridges. Practicing engineers will find the charts, tables, and design formulas especially valuable. About the authors:
