The tables and diagrams concerning the properties of ordinary water substance - as offered in this booklet - are mainly meant for use by students at universities and colleges so that they may be able to solve problems in the fields of power and chemical engineering, where water and steam are serving as working or process medium. On the other hand the tables and diagrams should support engineers in research work and industrial practice to obtain a quick and reliable general view of the proper ties of water substance. The thermodynamic properties of state have been calculated according to a formu lation given by Haar, Gallagher and Kell; this formulation was preliminarily adopted in 1983 by the "International Association for the Properties of Steam" (lAPS). All the other properties have been calculated according to the respective "Releases" of lAPS. Only units of the "International System of Units" (SI-Units) and their decimal multi ples and parts have been used. The detailed conversion tables facilitate comparisons with former material. We hope that the "Student's Tables" will prove a useful source for both, students and engineers.

Populist parties and movements are now a force to be reckoned with in many Western European countries. These groups are known for their opposition to immigration, their "anti-establishment" views, and their concern for protecting national culture. Their rise in popularity has gone hand-in-hand with the advent of social media, and they are adept at using new technology to amplify their message, recruit, and organize. The online social media following for many of these parties dwarfs the formal membership, consisting of tens of thousands of sympathizers and supporters. This mélange of virtual and real political activity is the way millions of people--especially young people--relate to politics in the 21st century. This is the first quantitative investigation into these digital populists, based on over 10,000 survey responses from 12 countries. It includes data on who they are, what they think and what motivates them to shift from virtual to real-world activism. It also provides new insight into how populism--and politics and political engagement more generally--is changing as a result of social media. The New Face of Digital Populism, a publication of the UK think tank Demos, calls on mainstream politicians to respond to and address concerns over immigration and cultural identity without succumbing to xenophobic solutions. People must be encouraged to become actively involved in political and civic life, whatever their political persuasion--it is important to engage and debate forcefully with these parties and their supporters, not shut them out as beyond the pale. The Open Society Foundations organized the conference "We Say What You Think: Is populism the Future of European Politics" in November 2011 to discuss the findings with policy makers, journalists and academics.

Carbosilanes are compounds in which the elements silicon and carbon alternate in the molecular skeleton [1]. Just as the alkanes are formally derived from the diamond lattice and the aromatics from the graphite lattice, the carbosilanes are structurally derived from silicon carbide. Because of the tetravalent nature of silicon and carbon we can expect stable linear, cyclic and polycyclic compounds to occur. However, carbosilanes do not exist in nature. This book is an attempt to give a summarized presentation. Carbosilanes are, of course, part" of organosilicon chemistry, but their behavior differentiates them distinctly from other organosilicon compounds. The differences result primarily from the alternating Si-C-Si arrangements in the molecular skeleton, and especially the various methylene bridges (CH , CHX, CX ; X = halogen) cause changes in z z Si-C bond polarization and hence influence the reaction possibilities. It is convenient to regard carbosilanes as similar to silicones except that the oxygen bridges of silicones are replaced by methylene units. However, this does not accurately account for all the chemical properties of these compounds. Carbosilanes are related more directly to silicon carbide, as shown occasionally by the reactive behavior of polycyclic car bosilanes. Therefore, in view of the present interest shown for thermally stable cera mics of unusual character, interesting possibilities arise for further development. Most cyclic carbosilanes can be classified in two groups: the carborundanes and the Si-scaphanes. Compounds belonging to the carborundane class maintain Si-C six-membered rings in the boat conformation.

Vitamin C is the first book to cover the history, chemistry, biochemistry, and medical importance of vitamin C and is the first to provide an in-depth, interdisciplinary study of this essential and fascinating compound. The book provides a comprehensive and systematic account of the vitamin C story, fully surveying the history of scurvy and how its cure led to the suggestion, discovery, and isolation of the vitamin, later named L-ascorbic acid. It describes in detail the vitamin's structure determination, synthesis and manufacture, and its oxidation products, derivatives and related compounds. Its key biochemical roles are fully categorized and explained, and the medical importance of the vitamin, including the recent use of so-called megadoses, is thoroughly discussed. Vitamin C will be of interest to a very wide readership and will provide useful background information and inspiration for students at various levels. It will also be relevant to the interested chemist or lay person, as well as those carrying out research in this area.

By employing a combination of approaches from several disciplines the authors elucidate the principles of a variety of biomechanical systems that rely on frictional surfaces or adhesive secretions to attach parts of the body to one another or to attach organisms to a substrate. This account provides an excellent starting point for engineers and physicists working with biological systems and for biologists studying friction and adhesion. It will also serve as a valuable introduction for graduate students entering this interdisciplinary field of research.
