Book Description
This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.

Book Description
The publication is the first in a new series on existing and innovative paradigms in Heritage Studies. The series aims at systematising and developing the academic discourse on heritage, which has yielded a wealth and breadth of contributions over the past few years. The publication offers its own emphasis by developing heritage studies with a perspective towards and as a contribution to human development. It thus offers a vision for the construction and establishment of a new discipline. The academic mainsprings and research interests of this repositioning of heritage studies as an academic discipline are discussed by internationally renowned thinkers and heritage practitioners. The publication thus establishes first important points for discussion. Central to this publication are questions concerning the sustainable protection and use of heritage, focussing on the world cultural heritage and intangible cultural heritage, but equally questions on the relation of heritage and memory and how these could mutually enrich our understanding of heritage.

Book Description
Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Book Description
Environmental concerns regarding continuous use of synthetic dyes saw a revival in the demand for natural dyes as natural dyes exhibit better biodegradability and generally have a higher compatibility with the environment. However, one of the limitations on the use of natural dyes or pigments is the low extraction yield factors (a few grams of pigment per kg of dried raw material). Therefore, the exploitation of other biological sources such as fungi, bacteria and cell cultures offers interesting alternative. Microbial pigments such as from bacterial origins offer the advantage in terms of production compared to pigments extracted from vegetables or animals, due to its simple cell and fast culturing technique. This book offers interesting insight into initial works carried out to demonstrate the potential use of bacterial pigment as colorant for various applications.

Book Description
Machu Picchu, recently voted one of the New Wonders of the World, is one of the world's most famous archaeological sites, yet it remains a mystery. Even the most basic questions are still unanswered: What was its meaning and why was it built in such a difficult location? Renowned explorer Johan Reinhard attempts to answer such elusive questions from the perspectives of sacred landscape and archaeoastronomy. Using information gathered from historical, archaeological, and ethnographical sources, Reinhard demonstrates how the site is situated in the center of sacred mountains and associated with a sacred river, which is in turn symbolically linked with the sun's passage. Taken together, these features meant that Machu Picchu formed a cosmological, hydrological, and sacred geological center for a vast region.
