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
This publication results from a technical meeting on phenomenology and technologies relevant to in-vessel melt retention (IVMR) and ex-vessel corium cooling (EVCC). The purpose of the publication is to capture the state of knowledge, at the time of that meeting, related to phenomenology and technologies as well as the challenges and pending issues relevant to IVMR and EVCC for water cooled reactors by summarizing the information provided by the meeting participants in a form useful to practitioners in Member States.

Flexoelectricity in Liquid Crystals

Book Description
The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Book Description
Dozens of books about Wikipedia are available, but they all focus on the English Wikipedia and assume an Anglo-Saxon perspective, while disregarding cultural and language variability or multi-cultural collaborative efforts. They address the impact of Wikipedia on society, processes of mass knowledge production, and the dynamics of the Wikipedia community. However, none of them focus on Wikipedia’s global features. This lack of attention presents a serious problem because more than 80% of Wikipedia articles are written in languages other than English---in fact, Wikipedia includes articles in 285 languages. Global Wikipedia: International and Cross-Cultural Issues in Online Collaboration is the first book to address this gap by focusing attention on the global, multilingual, and multicultural aspects of Wikipedia. The editors showcase research on Wikipedia, exploring a wide range of international and cross-cultural issues. Online global collaboration, coordination, and conflict management are examined in this rich socio technical environment. Special emphases include International and cross-cultural collaboration; Intercultural synergy on Wikimedia; Conflict and collaboration in editing international entries; Case studies of Chinese, Finnish, French, and Greek Wikipedias; and, Cross-cultural studies that compare more than one Wikipedia, focusing on content, structures, policies, contributions, interactions, processes, motivations, and challenges.
