Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses.
Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to “democratize” membrane filtration have been presented. Riverbank filtration is a “natural” filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

"Nonlinear Deformable-body Dynamics" mainly consists in a mathematical treatise of approximate theories for thin deformable bodies, including cables, beams, rods, webs, membranes, plates, and shells. The intent of the book is to stimulate more research in the area of nonlinear deformable-body dynamics not only because of the unsolved theoretical puzzles it presents but also because of its wide spectrum of applications. For instance, the theories for soft webs and rod-reinforced soft structures can be applied to biomechanics for DNA and living tissues, and the nonlinear theory of deformable bodies, based on the Kirchhoff assumptions, is a special case discussed. This book can serve as a reference work for researchers and a textbook for senior and postgraduate students in physics, mathematics, engineering and biophysics. Dr. Albert C.J. Luo is a Professor of Mechanical Engineering at Southern Illinois University, Edwardsville, IL, USA. Professor Luo is an internationally recognized scientist in the field of nonlinear dynamics in dynamical systems and deformable solids.

Stable, safe, secure and readily available water supply is one of the key factors in ensuring a good level of the public health and a stable society. Scientific assessments show that about 80 % of diseases and one-third of the total death toll in the developing countries are caused by the low quality of the drinking water. Other countries are also suffering from water shortages and insufficient quality of the drinking water. Many rivers in Europe and in other parts of the world are significantly polluted by insufficiently treated or untreated wastewater discharge.
This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Lviv, Ukraine, and addressed recent advances in water supply and wastewater treatment as a prerequisite for a safer society and environment. The contributions critically assess the existing knowledge on urban water management and provide an overview of the current water management issues, especially in the countries in transition in Central and Eastern Europe and in the Mediterranean Dialogue countries.

The Concise Oxford Dictionary of Mathematics, 4 edition
Oxf.rd University Press, USA; | 2009 | ISBN: 0199235945 | 528 pages | PDF | 6,1 MB
Authoritative and reliable, this superb reference contains more than 3,000 alphabetically arranged entries, providing clear jargon-free definitions of even the most technical mathematical terms. Ranging widely from Achilles paradox to zero matrix, the dictionary uses graphs, diagrams, and charts to render definitions as comprehensible as possible, offering an ideal introduction to subjects such linear algebra, optimization, nonlinear equations, and differential equations. The Dictionary covers both pure and applied mathematics as well as statistics, and there are entries on major mathematicians and on mathematics of more general interest, such as fractals, game theory, and chaos. The volume also contains valuable appendices of useful and relevant extra information, including lists of Nobel Prize winners and Fields medalists and lists of formulae. Fully revised and updated, this edition features many entry-level web links, which are accessible and continually updated via the Dictionary of Mathematics companion website, making the book indispensable for students and teachers of mathematics and for anyone encountering mathematics in the workplace.

The Handbook of Sustainable Refurbishment: Volume 1: Non-Domestic Buildings
Nick V. Baker, "The Handbook of Sustainable Refurbishment: Volume 1: Non-Domestic Buildings"
Earthscan | 2009 | ISBN: 1844074862 | 190 pages | PDF | 10,7 MB
The refurbishment of existing buildings is a neglected subject within sustainable architecture; attention is usually focused on new buildings. Old buildings can use large amounts of energy and provide poor internal conditions for occupants. They may have high heating demand, poor lighting, poor ventilation, solar penetration and glare, and poor control of heating and cooling. Demolition is an option but the alternative of refurbishment is starting to be seen as more sustainable in terms of architectural value, materials use, neighborhood disruption and waste disposal. Building new is more carbon intensive and carries many wider environmental impacts. In addition, the potential impact of low energy refurbishment is much greater than that for new build since there are many more existing buildings than will be built in the next 10 - 20 years, the period over which many CO2 emission targets apply.
The Handbook of Sustainable Refurbishment: Volume 1: Non-Domestic Buildings offers architects, engineers and a wide range of building professionals practical advice, illustrated by real examples. It moves from principles of sustainable refurbishment to specific design and engineering guidance. It emphasizes the need for an integrated approach by showing how refurbishment measures interact with one and other, and with the occupants, and how performance is ultimately influenced by this interaction.
