Variational and Quasi-Variational Inequalities in Mechanics
The variational method is a powerful tool to investigate states and processes in technical devices, nature, living organisms, systems, and economics. The power of the variational method consists in the fact that many of its sta- ments are physical or natural laws themselves. The essence of the variational approach for the solution of problems rel- ing to the determination of the real state of systems or processes consists in the comparison of close states. The selection criteria for the actual statesmust be such that all the equations and conditions of the mathematical model are satis?ed. Historically, the first variational theory was the Lagrange theory created to investigate the equilibrium of finite-dimensional mechanical systems under holonomic bilateral constraints (bonds). The selection criterion proposed by Lagrange is the admissible displacement principle.
Valuing Environmental Amenities Using Stated Choice Studies : A Common Sense Approach to Theory and Practice
Provides practical, research-based advice on how to conduct high-quality stated choice studies. It covers every aspect of the topic, from planning and writing the survey, to analyzing results, to evaluating quality. Chapters by highly-regarded academics and professionals are provided on rarely-discussed topics such as "supporting questions” and experimental design, as well as state-of-the-art multinomial choice modelling, attribute processing, the role of information, and lessons learned from the field of experimental economics. There is no other book on the market today that so thoroughly addresses the methodology of stated choice. Academics and practitioners in fields such as environmental, health and transportation economics, and marketing, will need this book on their shelves – and they will refer to it often.
Valued Fields
In this book, the theory of valuations as well as of Henselizations is developed. The presentation is based on the knowledge acquired in a standard graduate course in algebra. The last chapter presents three applications of the general theory -as to Artin's Conjecture on the p-adic number fields- that could not be obtained by the use of absolute values only.
Vaccine Adjuvants
The authors lay down a rational basis for vaccine adjuvant function and analyze a number of significantly distinct adjuvant-active molecules to illuminate the principles of their function and use. The focus is on specific receptor-ligand interactions, including the molecular features needed for a compound to possess adjuvant activity. The critical interface zone between the innate and adaptive immune systems is also analyzed to show how adjuvants exert their effects on T- and B-cell activation. Additional chapters address the possibility of tailoring adjuvants to yield optimally safe and effective responses.

Uranium, Mining and Hydrogeology
Subject of the book is Uranium and its migration in aquatic environments. The following subjects are emphasised: Uranium mining, Phosphate mining, mine closure and remediation, Uranium in groundwater and in bedrock, biogeochemistry of Uranium, environmental behavior, and modeling. Particular results from the leading edge of international research are presented.
Uranium in the Environment : Mining Impact and Consequences
Uranium is an element to be found ubiquitous in rock, soil, and water. Uranium concentrations in natural ground water can be more than several hundreds µg/l without impact from mining, nuclear industry, and fertilizers. Considering the WHO recommendation for drinking water of 15 µg/l (has been as low as 2 µg/l before) due to the chemical toxicity of uranium the element uranium has become an important issue in environmental research. Besides natural enrichment of uranium in aquifers uranium mining and milling activities, further uranium processing to nuclear fuel, emissions form burning coal and oil, and the application of uranium containing phosphate fertilizers may enrich the natural uranium concentrations in soil and water by far.
University and school collaborations during a pandemic : Sustaining educational opportunity and reinventing education
Based on twenty case studies of universities worldwide, and on a survey administered to leaders in 101 universities, this open access book shows that, amidst the significant challenges caused by the COVID-19 pandemic, universities found ways to engage with schools to support them in sustaining educational opportunity. In doing so, they generated considerable innovation, which reinforced the integration of the research and outreach functions of the university. The evidence suggests that universities are indeed open systems, in interaction with their environment, able to discover changes that can influence them and to change in response to those changes. They are also able, in the success of their efforts to mitigate the educational impact of the pandemic, to create better futures, as the result of the innovations they can generate.
Unifying the Software Process Spectrum ; International Software Process Workshop, SPW 2005, Beijing, China, May 25-27, 2005 Revised Selected Papers
This volume contains papers presented at SPW 2005, the Software Process Workshop held in Beijing, P. R. China, on May 25-27, 2005, and prepared for final publication. The theme of SPW2005 was “Unifying the Software Process Spectrum. ” Software process encompasses all the activities that aim at developing or evolving software products. The expanding role of software and information systems in the world has focused increasing attention on the need for assurances that software systems can be developed at acceptable speed and cost, on a predictable schedule, and in such a way that resulting systems are of acceptably high quality and can be evolved surely and rapidly as usage contexts change.
Unfolding Social Constructionism
This book examines social constructionism as a metatheory of psychology. It does not consider constructionist accounts of psycho-social phenomena, but it does assess certain assumptions which are said to underpin those accounts, assumptions which are primarily semantic and epistemological.

Understanding Non-equilibrium Thermodynamics : Foundations, Applications, Frontiers
Our time is characterized by an explosion of information and by an accel- ation of knowledge. A book cannot compete with the huge amount of data available on the Web. However, to assimilate all this information, it is n- essary to structure our knowledge in a useful conceptual framework. The purpose of the present work is to provide such a structure for students and researchers interested by the current state of the art of non-equilibrium th- modynamics. The main features of the book are a concise and critical pres- tation of the basic ideas, illustrated by a series of examples, selected not only for their pedagogical value but also for the perspectives o?ered by recent technological advances. This book is aimed at students and researchers in physics, chemistry, engineering, material sciences, and biology. We have been guided by two apparently antagonistic objectives: gener- ity and simplicity. To make the book accessible to a large audience of n- specialists, we have decided about a simpli?ed but rigorous presentation. Emphasis is put on the underlying physical background without sacri?cing mathematical rigour, the several formalisms being illustrated by a list of - amplesandproblems.
Understanding Models for Learning and Instruction : Essays in Honor of Norbert M. Seel
For more than 25 years, the pioneering research and theories of Norbert Seel have had a profound impact on educational thought in mathematics. In this special tribute, an international panel of researchers present the current state of model-based education: its research, methodology, and technology. Fifteen stimulating, sometimes playful chapters link the multiple ways of constructing knowledge (and domains as diverse as cognitive science, computer science, and philosophy) to the complex real world of skill development; generalize model-based theories into educational settings; and explain how to design and evaluate model-centered learning environments. Extensive reading lists, provocative graphics, and a wealth of cultural touchstones from the Bible to Bob Dylan make Understanding Models for Learning and Instruction an accessible yet thought provoking collection.
Understanding Industrial Transformation : Views from Different Disciplines
A scientist can only come to a partial understanding of industrial transformation processes. This is so not only because of the vastness of the topic, but because of the inherent limitations of each scientific discipline. The common ground, which scientists of different disciplines may endeavour to find when approaching some problem, is often slight. A scientist entering such grounds runs the risk of getting lost, losing understanding and only catc+I1189hing the loose tail mentioned above. Secondly, sciences, to make a difference, must impress their importance upon the public and convince scientific and policy institutions in order to obtain the means to carry out their mission.
