Henry Petroski's lyrical history of bridge builders in America is organized around five engineers: James Eads (inventor of the diving bell, which bridged Mississippi at St. Louis); Theodore Cooper (railroad bridge engineer and designer of the ill-fated Quebec Bridge); Gustav Lindenthal (Hell Gate Bridge, New York); Othmar Ammann (George Washington and Verrazano-Narrow bridges); and David Steinman (Mackinac bridge). Petroski's opening and closing chapters, "Imagine" and "Realize," remind us how a bridge starts out as a dream of engineering, but ends as a reality of compromise and maintenance. Edward Tenner says that "The profound contribution of Engineers of Dreams is to remind us that communication across generations may be the most important bridge of all."

Monitoring of Water Quality: The Contribution of Advanced Technologies
Author: F. Colin et al. | Size: 13.50 MB | Format:PDF | Publisher: Elsevier Science | Year: 1998 | pages: 269 | ISBN: ISBN10: 0080432034 & ISBN13: 9780080432038
Book Description:
Water can be considered as one of the basic elements supporting life and the natural environment, a primary component for industry, a consumer item for humans and animals and a vector for domestic and industrial pollution. Various European Directives already provide a framework for the control of aquatic substances, the quality of bathing, surface and drinking water and effluent control.
Such regulatory measures are closely related to analytical measurements. In order to comply with these regulations on a permanent basis, treatment plants and distribution companies, as well as water users and polluters, need to implement automated measuring techniques, such as sensors and other analytical tools in continuous or sequential mode to obtain suitable alarm systems and facilitate the management of water resources and decision making processes.
This approach is in continuous evolution within the European Union. In view of the consequences of wrong measurements, it is vital that reliable quality control systems be achieved and maintained. At present, only a small range of analytical parameters can be measured automatically, it is therefore necessary to develop and validate new methods to extend the list of parameters. The development of new methodologies requires that the

This book consolidates much of what is known about the geochemistry of arsenic and provides new information on relationships between high concentrations of arsenic in ground water and geochemical environments. The subject matter of this book ranges in scope from molecular-scale geochemical processes that affect the mobility of arsenic in ground water, to arsenic contaminated ground water at the national scale. Chapters were contributed by an international group of research scientists from a broad range of backgrounds.

Hi friends,
I almost sure that you're all ever getting problem, that you need your CAD Drawing should not be copied or distributed by other who you send the file.
So my problem is how can I protect a drawing I am sending to someone, with something like stamps, that hidden in model, but always seen if they print the file?
This case, remember me about stamp: "Produced by an Autodesk Educational Product".
But..., in my mind, can we protect our CAD Drawing with stamps, that we can create by ourself like: "created by jupe01 "
if VBA or AutoLisp is a solution, how it make us sure that the code always load when the file open. Isn't it any option "don't load or disable"?
thanks before for anyone who can give me solution,
