The distinguished mathematician wrote this informative book to explain the association of projective and descriptive geometry. Starting with a survey of the formulations of the axioms, he examines associated projective space, ideal points, the general theory of correspondence, axioms of congruence, infinitesimal rotations, the absolute, and metrical geometry.

Many topical talks given at the numerous symposia are included. Most of these were organized collaboratively by several of the divisions of the Arbeitskreis.

Modern imaging methods have made it possible to detect breast cancer at an earlier stage than in the past. Nevertheless, a large majority of suspicious findings at screening subsequently prove to be benign. It is therefore important to be able to identify benign lesions in a manner that is reliable, tissue sparing, patient friendly, and cost-effective.

In this excellent book, the authors have described advances in the neoadjuvant chemotherapeutic management of a number of tumor types. Those who read and study the content of the chapters in this book will come away with a far greater understanding of the rationale supporting neoadjuvant chemotherapy, the existing evidence-based data regarding its use, limitations of the approach, and required future investigative efforts to learn how to optimize the benefits of this innovative management concept.

This book provides an excellent overview of the molecular mechanics underlying bladder carcinoma and their role in current and future therapy and would be integral for clinicians and researchers in the field of bladder cancer.

Die Evolutionstheorie hat sich in den letzten 150 Jahren von einer speziellen naturwissenschaftlichen zur universellen wissenschaftlichen Theorie entwickelt. Sie bezieht Phänomene von der Lebensentstehung bis zu den kulturellen und geistigen Entwicklungen des Menschen ein. Die Evolutionstheorie ist das Fundament der modernen Biologie.

This volume tracks the development in the United States of the field of Bioethics, Ethics applied to the disciplines of medicine, nursing, and health care in general, including medical research and the complex economic and political problems surrounding the provision of medical and nursing care. It explains how the United States developed, case by case, the central rules and principles of ER ethics in the Health Care System.

The role of singular trajectories in control theory is analysed in this volume that contains about 60 exercieses and problems. A section is devoted to the applications of singular trajectories to the optimisation of batch reactors. The theoretical paart based on the Martinet case concerns the singulatrity analysis of singular trajectories in sub-Riemannian geometry.
