A critical aspect of sustainability associated with water and wastewater systems is to maintain and manage infrastructure in the most efficient and economical manner while complying with environmental regulations and keeping rates at acceptable levels.
Given the high cost of fuel, our growing population, and the associated increase in energy needs, it is important to address energy use and future energy availability for the treatment of the water we drink and the water we pollute. Water & Wastewater Infrastructure: Energy Efficiency and Sustainability addresses these issues, detailing the processes that can assist facilities to become more energy efficient and providing guidance to ensure their sustainability.
The text begins with brief descriptions of the water and wastewater treatment industries. It then describes some of the basics of energy and discusses what planning for a sustainable energy future in water and wastewater treatment plants entails. The author explores energy-saving options and provides case studies to demonstrate how some facilities have used equipment, technology, and operating strategies to save money and reduce their impact. The energy-efficient technologies include combined heat and power (CHP), gas turbines, microturbines, reciprocating engines, steam turbines, and fuel cells. The author also addresses biomass power and biogas.
The section on sustainability and renewable energy covers hydropower, solar power, and wind power as well as energy conservation measures for treating wastewater. Nine appendices provide individual case studies that present evaluations of energy conservation measures, results, payback analysis, and conclusions. This book addresses the challenges faced by water and wastewater treatment facilities by examining how they can operate in ways that provide economic and environmental benefits, save money, reduce environmental impact, and lead to sustainability.

I have query regarding the piracy of the softwares.
my question to all is
DOES THE PIRATED SOFTWARES GIVE BAD RESULTS FOR THE CALCULATIONS / SIMULATIONS? I MEAN CAN ONE BE DEPENDENT ON THE RESULTS GIVEN BY A PIRATED SOFTWARE?
To my understanding I personally feel that the fully unlocked/pirated software will perform as good as a genuine software. However, it can happen that some modules in the cracked softwares may be locked but those modules which are unlocked will be performing perfectly.
I would like sum pros to throw sum light on this topic.

The construction industry is the largest single waste producing industry in the UK. Ensuring a supply chain of recycled materials affords many potential gains, achieved through: reducing the material volume transported to already over-burdened landfill sites, possible cost reductions to the contractor/client when considering the landfill tax saved and the potential for lower cost material replacements, a reduction in the environmental impact of quarrying and the saving of depleting natural material resources.
Reuse of Materials and Byproducts in Construction: Waste Minimization and Recycling addresses use of waste and by products in the construction industry. An over view of new “green” design guides to encourage best practice will be examined and current legislation that channels on site practices, such as site waste management plans. Fundamental individual construction materials are discussed and the process of reforming by products and waste products into new construction materials is investigated, examining the material performance, energy required to convert waste into new products and viability of recycling. The main range of constructional materials will be examined.
Aimed at postgraduate students, lecturers and researchers in construction and civil engineering, the book will also be of interest to professional design practices.

The aim of this book is to present the latest findings in the properties and application of Supplementary Cementing Materials and blended cements currently used in the world in concrete. Sustainability is an important issue all over the world. Carbon dioxide emission has been a serious problem in the world due to the greenhouse effect. Today many countries agreed to reduce the emission of CO2. Many phases of cement and concrete technology can affect sustainability. Cement and concrete industry is responsible for the production of 7% carbon dioxide of the total world CO2 emission. The use of supplementary cementing materials (SCM), design of concrete mixtures with optimum content of cement and enhancement of concrete durability are the main issues towards sustainability in concrete industry.

Materials and Joints in Timber Structures: Recent Developments of Technology
Author: Ida Näslund, Helena Johnsson (auth.), Simon Aicher, H.-W. Reinhardt, Harald Garrecht (eds.) | Size: 48 MB | Format:PDF | Quality:Unspecified | Publisher: Springer | Year: 2014 | pages: 815 | ISBN: 9789400778108
This book contains the contributions from the RILEM International Symposium on Materials and Joints in Timber Structures that was held in Stuttgart, Germany from October 8 to 10, 2013. It covers recent developments in the materials and the joints used in modern timber structures. Regarding basic wooden materials, the contributions highlight the widened spectrum of products comprising cross-laminated timber, glulam and LVL from hardwoods and block glued elements. Timber concrete compounds, cement bonded wood composites and innovative light-weight constructions represent increasingly employed alternatives for floors, bridges and facades. With regard to jointing technologies, considerable advances in both mechanical connections and glued joints are presented. Self-tapping screws have created unprecedented options for reliable, strong as well as ductile joints and reinforcement technologies. Regarding adhesives, which constitute the basis of the jointing/laminating technology of modern timber products, extended options for tailor-made bonding solutions have to be stated. Apart from melamine-urea and phenolic-resorcinol adhesives, one-component-polyurethanes, emulsion isocyanate polymers and epoxies offer a wide range of possibilities. The contributions dealing with experimental and numerical investigations on static, cyclic and seismic behavior of structures clearly reveal the enhanced potential of modern timber construction for reliable and sustainable buildings and bridges of the new millennium.
The book is structured in nine thematic areas, being
I) Structures
II) Mechanical Connections
III) Glued Joints and Adhesives
IV) Timber and Concrete/Cement/Polymer Composites
V) Cyclic, Seismic Behavior
VI) Hardwood, Modified Wood and Bamboo
VII) Cross-Laminated Timber
VIII) Properties and Testing of Wood
IX) Glulam

This book introduces to the theory of structural dynamics, with focus on civil engineering structures that may be described by line-like beam or beam-column type of systems, or by a system of rectangular plates. Throughout this book the mathematical presentation contains a classical analytical description as well as a description in a discrete finite element format, covering the mathematical development from basic assumptions to the final equations ready for practical dynamic response predictions. Solutions are presented in time domain as well as in frequency domain. Structural Dynamics starts off at a basic level and step by step brings the reader up to a level where the necessary safety considerations to wind or horizontal ground motion induced dynamic design problems can be performed. The special theory of the tuned mass damper has been given a comprehensive treatment, as this is a theory not fully covered elsewhere. For the same reason a chapter on the problem of moving loads on beams has been included.
