A number of general-purpose, reasonably accurate and well-tested ab-initio codes for crystals are discussed in this book. The aim is to expand competence of their application in material sciences and solid-state physics. The book addresses particularly readers with a general knowledge in quantum chemistry and intends to give a deeper insight into the special algorithms and computational techniques in ab-initio computer codes for crystals. Three different programs which are available to all interested potential users on request are presented.

This volume gives the proceedings of the ninth Symposium on Theoretical Aspects of Computer Science (STACS). This annual symposium is held alternately in France and Germany and is organized jointly by the Special Interest Group for Fundamental Computer Science of the Association Francaise des Sciences et Technologies de l'Information et des Syst mes (AFCET) and the Special Interest Group for Theoretical Computer Science of the Gesellschaft f}r Informatik (GI). The volume includes three invited lectures and sections on parallel algorithms, logic and semantics, computational geometry, automata...

Specialists from diverse disciplines discuss the important topics of Tissue Repair and Fibrosis. The Role of Myofibroblast. The Myofibroblast is implicated in many processes, such as tissue repair,fibrosis, and stromal reaction to tumors. This book seeks to provide an overview of the knowledge accumulated since this cell was first describes 25 years ago. Discussions focusses on three main topics: - Cellular and molecular biology of fibroblast and myofibroblasts - Wound healing: experimental models, and - Human fibrocontracted diseases.

Toxoplasmosis is a ubiquitous infection, contracted by at least a third of the population in most areas of the globe. Clinical disease arises rarely, usually unexpectedly, but sometimes with disastrous effects on the patient. Humans, pets, farm and zoo animals may contract toxoplasmosis, possibly involving any clinical laboratory in its diagnosis. Pathologists must ponder the clinical significance of a hyperplastic l. ymph node, a cyst found at autopsy, or a serologic titer. Serving as scientific physicians, pathologists are asked: How is toxoplasmosis diagnosed? 'What is the treatment for...
