This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

The topics covered in this proceedings include: synthesis of the heaviest isotopes of the lightest elements and the study of their properties, properties of neutron and proton-rich nuclei, some astrophysical problems, cluster radioactivity, present status and perspectives of producing radioactive nuclear beams and their applications, and new experimental facilities and projects.

This book of proceedings contains contributions of about 30 prominent scientists who were or are associated with the awardee, Prof J B Natowitz, and are working in the field of heavy-ion reactions.The papers contained in this book represent an up-to-date overview of the most interesting topics related to the formation and decay of hot nuclei and to nuclear dynamics.

The difficulties in determining the quality of information on the Internet--in particular, the implications of wide access and questionable credibility for youth and learning. Today we have access to an almost inconceivably vast amount of information, from sources that are increasingly portable, accessible, and interactive. The Internet and the explosion of digital media content have made more information available from more sources to more people than at any other time in human history. This brings an infinite number of opportunities for learning, social connection, and entertainment. But at the same time, the origin of information, its quality, and its veracity are often difficult to assess. This volume addresses the issue of credibility--the objective and subjective components that make information believable--in the contemporary media environment. The contributors look particularly at youth audiences and experiences, considering the implications of wide access and the questionable credibility of information for youth and learning. They discuss such topics as the credibility of health information online, how to teach credibility assessment, and public policy solutions. Much research has been done on credibility and new media, but little of it focuses on users younger than college students. Digital Media, Youth, and Credibility fills this gap in the literature.

The book provides a comprehensive guide to the construction, operation, diagnostics, and applications of electron impact ion sources for the production of highly charged ions. Beside the treatment of elementary processes and ion storage in electron impact ion sources, characteristic diagnostic methods for these sources are described which are related to plasma diagnostics. Related to atomic and solid state physics the use of electron impact ion sources is discussed. Diese Monographie behandelt den Aufbau, den Betrieb, die Diagnostik und Anwendungen von Elektronenstoß-Ionenquellen zur Erzeugung hochgeladener Ionen. Neben der Behandlung von Basisprozessen in den Quellen erfolgt eine umfangreiche Beschreibung von Diagnostikmethoden mit Relevanz zur Ionenquellen- und Plasmadiagnostik.

The last few years have seen great progress in the understanding of nuclei far from stability, i.e. nuclei with a composition that differs radically from that of the stable nuclei that we encounter in Nature. It has become clear that the study of exotic nuclear species reveals many new phenomena, which may make us go back, armed with new insight, to more familiar nuclear systems. The proceedings at the 4th course of the International School of Heavy Ion Physics — Exotic Nuclei, containing the lectures and seminars by world specialists in the field, cover some of the central themes of the physics of exotic nuclei which lie at the forefront of nuclear research.
