This book provides a comprehensive understanding of the design and construction of waterretaining structures. allowing graduate civil and structural engineering students. as well
as the practising engineer. to design with speed and economy. Assuming some familiarity with BS 8110 Structural Use of Concrete the book draws on examples. many of which
are based on actual completed structures. and upon extensive tables. related to the analysis of rectangular. circular and conical structures, to develop good working practice. The tables and examples will enable the engineer to check, by hand, the often complex results of computer analysis and output. usually based on the finite element method. for most structures. This is particularly so in those cases where the forces within a structure are affected by the ground upon which they sit. Thus, methods of designing for the soil/structure interaction, which normally require the aid of complex computer programs. are included. The tables and examples will prove to be a good reference for carrying out new work to modern methods and regulations. and will give direction to the student engineer in the use of currrent British Standards for the design of many types of concrete structures.
An essential part of the book are the listed computer programs and output which further assist the designer in obtaining a range of options from which the most effective and economical solution may be determined for a particular structure; whilst a useful appendix covers the analysis of ground-supported open circular concrete tanks.

Steels: Metallurgy and Applications, Third Edition
Author: D. T. Llewellyn, Roger C. Hudd | Size: 19.53 MB | Format:PDF | Quality:Unspecified | Publisher: Butterworth-Heinemann | Year: 1998 | pages: 400 | ISBN: 0750637579
STEELS provides a metallurgical understanding of commercial steel grades and the design, manufacturing and service requirements that govern their application. The properties of different steels are described, detailing the effect of composition, processing and heat treatment. Where appropriate an introduction is given to standard specifications and design codes provided on component manufacture and property requirements for successful service performance.

Author: Committee on River Science at the U.S. Geological Survey | Size: 14 MB | Format:PDF | Quality:Unspecified | Publisher: National Research Council | Year: 2007-05-04 | pages: 207 | ISBN: 0309103576
Rivers provide about 60 percent of the nation’s drinking water and irrigation water and 10 percent of the nation’s electric power needs. The multiple and sometimes incompatible services demanded of rivers often lead to policy and management conflicts that require the integration of science-based information. This report advises the U.S. Geological Survey on how it can best address river science challenges by effectively using its resources and coordinating its activities with other agencies. The report identifies the highest priority river science issues for the USGS, including environmental flows and river restoration, sediment transport and geomorphology, and groundwater surface-water interactions. It also recommends two cross-cutting science activities including surveying and mapping the nation’s river systems according to key physical and landscape features, and expanding work on predictive models, especially those that simulate interactions between physical-biological processes. The report identifies key variables to be monitored and data-managed. It proposes enhancements in streamflow, biological, and sediment monitoring; these include establishing multidisciplinary, integrated reach-scale monitoring sites and developing a comprehensive national sediment monitoring program. Finally, it encourages the USGS to be at the forefront of new technology application, including airborne lidar and embedded, networked, wireless sensors.

The procedures for verifying the strength of railway bridges are covered by detailed and comprehensive rules of calculation already in existence. In contrast, serviceability limit states, notably deformation ELS, are described only in network calculation rules or in UIC leaflets.
In essence, bridges are deformable structures. These deformations must be controlled all the more accurately as trains travel at high, and very high speeds. The purpose of this leaflet is to specify the design requirements for rail-bridges as regards train/track/bridge interaction phenomena and in particular speed, thereby taking into account bridge resonance phenomena. It outlines the corresponding draft criteria and provides information on the phenomena to be controlled as well as the appropriate procedures for verifying the structures.
This leaflet should be used in conjunction with UIC Leaflet 776-1 .

Megaupload, one of the internet's largest file-sharing sites, has been shut down by officials in the US.
The site's founders have been charged with violating piracy laws.
Federal prosecutors have accused it of costing copyright holders more than $500m (£320m) in lost revenue. The firm says it was diligent in responding to complaints about pirated material.
In response, the hackers group Anonymous has targeted the FBI and US Department of Justice websites.
The news came a day after anti-piracy law protests, but investigators said they were ordered two weeks ago.
The US Justice Department said that Megaupload's two co-founders Kim Dotcom, formerly known as Kim Schmitz, and Mathias Ortmann were arrested in Auckland, New Zealand along with two other employees of the business at the request of US officials. It added that three other defendants were still at large.
"This action is among the largest criminal copyright cases ever brought by the United States and directly targets the misuse of a public content storage and distribution site to commit and facilitate intellectual property crime," said a statement posted on its website.
The FBI website was intermittently unavailable on Thursday evening due to what officials said was being "treated as a malicious act".
The hackers' group Anonymous said it was carrying out the attacks.
The Motion Picture Association of America's website also suffered disruption.
Third-party sites
The charges included, conspiracies to commit racketeering, copyright infringement and money laundering.
A federal court in Virginia ordered that 18 domain names associated with the Hong Kong-based firm be seized.
The Justice Department said that more than 20 search warrants had been executed in nine countries, and that approximately $50m (£32m) in assets had been seized.
It claimed that the accused had pursued a business model designed to promote the uploading of copyrighted works.
"The conspirators allegedly paid users whom they specifically knew uploaded infringing content and publicised their links to users throughout the world," a statement said.
"By actively supporting the use of third-party linking sites to publicise infringing content, the conspirators did not need to publicise such content on the Megaupload site.
"Instead, the indictment alleges that the conspirators manipulated the perception of content available on their servers by not providing a public search function on the Megaupload site and by not including popular infringing content on the publicly available lists of top content downloaded by its users."
Before it was shut down the site posted a statement saying the allegations against it were "grotesquely overblown".
"The fact is that the vast majority of Mega's internet traffic is legitimate, and we are here to stay," it added.
"If the content industry would like to take advantage of our popularity, we are happy to enter into a dialogue. We have some good ideas. Please get in touch."
Blackouts
The announcement came a day after thousands of websites took part in a "blackout" to protest against the Stop Online Piracy Act (Sopa) and the Protect Intellectual Property Act (Pipa).
The US Chamber of Commerce has defended the proposed laws saying that enforcement agencies "lack the tools" to effectively apply existing intellectual property laws to the digital world.
Industry watchers suggest this latest move may feed into the wider debate.
"Neither of the bills are close to being passed - they need further revision. But it appears that officials are able to use existing tools to go after a business alleged to be inducing piracy," said Gartner's media distribution expert Mike McGuire.
"It begs the question that if you can find and arrest people who are suspected to be involved in piracy using existing laws, then why introduce further regulations which are US-only and potentially damaging?"
