Dynamics of Ice Sheets and Glaciers presents an introduction to the dynamics and thermodynamics of flowing ice masses on Earth. Based on an outline of general continuum mechanics, the different initial-boundary-value problems for the flow of ice sheets, ice shelves, ice caps and glaciers are systematically derived. Special emphasis is put on developing hierarchies of approximations for the different systems, and suitable numerical solution techniques are discussed. A separate chapter is devoted to glacial isostasy. The book is appropriate for graduate courses in glaciology, cryospheric sciences, environmental sciences, geophysics and related fields. Standard undergraduate knowledge of mathematics (calculus, linear algebra) and physics (classical mechanics, thermodynamics) provide a sufficient background for successfully studying the text.

One of the most devastating weapons of the Middle Ages, the crossbow probably originated in the Western Roman Empire early in the fourth century, its design perhaps suggested by the balista, an ancient form of catapult. This book is the only work ever devoted exclusively to this widely used bowstring weapon. The author also deals with an arsenal of related weapons, from the siege engines, balistas and catapults of the ancients to such arms as the Turkish bow and the Chinese repeating crossbow. Enhanced with over 100 illustrations, ranging from contemporary battle pictures to scale constructional plans, and replete with scholarly detail and intriguing anecdotes, this classic study will interest historians, medievalists, sportsmen and any student of arms and armor. Abridged republication of The Crossbow, originally published by Longmans, Green, and Co., London, 1903. Part IV (appendix) Book of the Crossbow by Ralf Payne-Gallway
Deals with the fundamental properties of photon and light beams, both experimentally and theoretically. It covers the essentials of linear interactions and most of the nonlinear interactions between light and matter in both the transparent and absorbing cases. About 4000 references open access to original literature.
Entrepreneurship in the Healthcare sector has received increased attention over the last two decades, both in terms of scholarly research and number of innovative enterprises. Entrepreneurial activities and innovations have emerged from and will continue to be driven by several actors along the healthcare value chain but especially from non-traditional healthcare players. In this new volume, we present the reader with several critical issues in healthcare entrepreneurship and innovation, covering a comprehensive set of research topics. We bring together the latest academic research and management practice, with contributions by authors from entrepreneurship, medical sciences, and management, who provide in depth and practical insights into designing and managing entrepreneurship in healthcare. Upon providing a systematic review of the research field, we discuss several important macro-, meso-, and micro-level issues in healthcare entrepreneurship, such as opportunity identification, the entrepreneurial ecosystem including accelerators, the benefits of open innovation for the sector, and social entrepreneurship in healthcare. These topics open up avenues for nurturing entrepreneurship in healthcare through both education and policy. Building on this trend, the book is organized around levels of analysis and specifies which cross-disciplinary efforts are needed to advance understanding of how entrepreneurs discover opportunities and start viable and innovative businesses. Healthcare Entrepreneurship will be of interest scholars of health care and entrepreneurs alike, but also managers of innovative health care enterprises as well as policy makers in the health sector.
This book contains the elaborated and updated versions of the 24 lectures given at the 43rd Saas-Fee Advanced Course. Written by four eminent scientists in the field, the book reviews the physical processes related to star formation, starting from cosmological down to galactic scales. It presents a detailed description of the interstellar medium and its link with the star formation. And it describes the main numerical computational techniques designed to solve the equations governing self-gravitating fluids used for modelling of galactic and extra-galactic systems. This book provides a unique framework which is needed to develop and improve the simulation techniques designed for understanding the formation and evolution of galaxies. Presented in an accessible manner it contains the present day state of knowledge of the field. It serves as an entry point and key reference to students and researchers in astronomy, cosmology, and physics.
Sharper and more to the point than is the norm, The Power of Islam in a Europe of Tomorrow shows how Islam is influencing and altering European societies. With a wealth of examples drawn from both Denmark and other countries, Jespersen and Pittelkow describe a number of problems: Muslim parallel societies, the lost reliance, the oppression of women, the attacks on the free- dom of speech and democracy, crime and soci- etal dissolution, radicalism and anti-Semitism.
