The continuous growth in the demand for water supply and sanitation services has posed decision makers with the challenge to discover new, and to adapt existing, institutions. Since the last two decades, the most prominent institutional change for the water and sanitation sector is neo-liberalism. Neo-liberalism manifests itself in the water sector through privatization, private sector involvement and liberalisation. This book analyses whether neo-liberalism has had an effect on the institutions, the strategies, and the performances of water providers. Strategies are interpreted through what a water provider can do (strategic context), wants to do (strategic plans), and actually does (strategic actions). On the basis of studies in the Netherlands, the Netherlands Antilles, the United Kingdom and Italy, the book concludes that neo-liberal institutional changes matter for the strategies of water providers. However, it also finds that the inherent problems with performance interpretation, measurement and comparison obscure any accurate insight in the effect of neo-liberal institutional changes on performance. In this regard the book opens a window for research both on the relation between institutions and conduct, and between conduct and performance of water and sanitation providers.

STATISTICS IN PRACTICE A practical exploration of alternative approaches to analyzing water-related environmental issuesWritten by an experienced environmentalist and recognized expert in the field, this text is designed to help water resource managers and scientists to formulate, implement, and interpret more effective methods of water quality management.After presenting the basic foundation for using statistical methods in water resource management, including the use of appropriate hypothesis test procedures and some rapid calculation procedures, the author offers a range of practical problems and solutions on environmental topics that often arise, but are not generally covered.
These include:
* Formulating water quality standards
* Determining compliance with standards
* MPNs and microbiology
* Water-related, human health risk modeling
* Trends, impacts, concordance, and detection limits
In order to promote awareness of alternative approaches to analyzing data, both frequentist and Bayesian, statistical methods are contrasted in terms of their applicability to various environmental issues.
Each chapter ends with a number of set problems for which full answers are provided. The book also encourages discussion between technical staff and management before embarking on statistical studies.

Mathematical Analysis for Modeling provides you with better comprehension of how mathematics is developed for, and applies to, solving scientific and engineering problems. The author stresses developing mathematical descriptions of scientific and engineering situations, rather than rote memorization of proofs and formulas. Emphasis is placed on algorithms as solutions to problems, and on insight rather than on formal derivations. This book is for those who intend to conduct research in areas of science requiring the use and understanding of a substantial amount of mathematics, but who may not be well-versed in such applications.

Handbook of Grid Generation addresses the use of grids (meshes) in the numerical solutions of partial differential equations by finite elements, finite volume, finite differences, and boundary elements. Four parts divide the chapters: structured grids, unstructured girds, surface definition, and adaption/quality. An introduction to each section provides a roadmap through the material.
This handbook covers:
- Fundamental concepts and approaches
- Grid generation process
- Essential mathematical elements from tensor analysis and differential geometry, particularly relevant to curves and surfaces
- Cells of any shape - Cartesian, structured curvilinear coordinates, unstructured tetrahedra, unstructured hexahedra, or various combinations
- Separate grids overlaid on one another, communicating data through interpolation
- Moving boundaries and internal interfaces in the field
- Resolving gradients and controlling solution error
- Grid generation codes, both commercial and freeware, as well as representative and illustrative grid configurations. Handbook of Grid Generation contains 37 chapters as well as contributions from more than 100 experts from around the world, comprehensively evaluating this expanding field and providing a fundamental orientation for practitioners.

Abu Dhabi is famous for its extreme engineering, but now one project could surpass them all - the world's most inclined skyscraper, Capital Gate. Capital Gate is a tower that spirals out of the ground at 525 feet and tilts almost five times more than the Leaning Tower of Pisa. The tower will include a five-star hotel on the top 18 levels, an infinity pool, a restaurant hanging 300 feet above the ground and a helicopter pad on the roof.

An introduction to the Flux Core Arc Welding process, covering both self shielded and gas shielded flux cored welding wires. This video focuses on fundamental welder skills. Extremely close-up video of actual welds, with detailed explanations, demonstrate how the voltage and wire speed settings, electrode extension, gun angle, and travel speed affect penetration, the shape, and the size of the weld. Also included are weld joints, metal preparation, and joint fit-up.
Flux Core Arc Welding also provides a working knowledge of constant voltage power sources, wire feed units, and the unique characteristics of flux cored welding wires. Understanding the technical aspects of FCAW is an important part of setting up the equipment to provide the correct amount of weld, with good penetration and weld fusion.

Cape Town is building a brand-new stadium for the 2010 FIFA World Cup Games, but it is the last World Cup project to get started. Australian project manager Andy Fanton is struggling to keep it on schedule and make up for lost time. Green Point Stadium has to be finished in 12 months to be ready for its first practice games. The construction team will have a tough time getting there, with a largely inexperienced group of workers and a severe shortage of cranes. The stadium roof is the biggest challenge of all as it is made up of high-tension cables; if they are not perfectly tensioned, the roof will collapse.
