This text covers all aspects of the current diagnosis and treatment of acute cholecystitis. Different diagnostic tests are discussed as well as the preoperative evaluation needed to initiate treatment. Other sections include the management of acute cholecystitis in the critically ill and elderly patients, recent advances in operative strategies that have further altered the treatment of acute c…
The present volume aims to be a comprehensive survey on the derivation of the equations of motion, both in General Relativity as well as in alternative gravity theories. The topics covered range from the description of test bodies, to self-gravitating (heavy) bodies, to current and future observations. Emphasis is put on the coverage of various approximation methods (e.g., multipolar, post-N…
This superbly illustrated book on the surgical treatment of pediatric colorectal problems focuses in particular on the specific technical maneuvers that may be considered key to successful results. The presented management concepts are based on a database comprising over 5000 patients, more than 2300 of whom have been operated on by one of the authors as lead surgeon over the past 30 years. The…
This new edition presents information and knowledge on the field of biomedical devices and surgical tools. The authors look at the interactions between nanotechnology, nanomaterials, design, modeling, and tools for surgical and dental applications, as well as how nanostructured surfaces can be created for the purposes of improving cell adhesion between medical devices and the human body. Each o…
Featuring contributions from industry and academia, this volume includes chapters covering a diverse range of theoretical and empirical aspects of actuarial science and quantitative finance, including portfolio management, derivative valuation, risk theory and the economics of insurance. Developed from the First International Congress on Actuarial Science and Quantitative Finance, held at the U…
Activity Theory in Education: Research and Practice brings together cutting-edge scholars from a number of continents. Through in-depth case studies the authors highlight how Activity Theory is used in education and discuss the theoretical as well as pragmatic use of Activity Theory frameworks in a range of contemporary learning contexts. The first section of the book focuses on empirical resea…
This book is aimed at the reader who wishes to gain a working knowledge of time series and forecasting methods as applied to economics, engineering and the natural and social sciences. It assumes knowledge only of basic calculus, matrix algebra and elementary statistics. This third edition contains detailed instructions for the use of the professional version of the Windows-based computer pack…
This book offers a comprehensive guide to total knee arthroplasty (TKA) that will assist in achieving excellent outcomes based on a sound understanding and technique. After an introductory section on the native knee that covers the anatomy, physiology, biomechanics, and patterns of disease, all aspects of primary knee arthroplasty are discussed in detail. Individual chapters are devoted to topi…
Superfluidity – and closely related to it, superconductivity – are very general phenomena that can occur on vastly different energy scales. Their underlying theoretical mechanism of spontaneous symmetry breaking is even more general and applies to a multitude of physical systems. In these lecture notes, a pedagogical introduction to the field-theory approach to superfluidity is presented…
This publication summarizes the studies carried out at two of the most active volcanoes of Chiapas (Mexico): El Chichón and Tacaná. El Chichón erupted explosively in 1982 killing more than 2000 people being the worst volcanic disaster in Mexico, and Tacaná produced two mild phreatic explosions in 1950 and 1986. Only after these explosions a surge of new studies began to unreveal their volca…
