This book describes the anatomy of the posterior fossa, together with the main associated surgical techniques, which are detailed in numerous photographs and step-by-step color illustrations. The book presents approaches and surgical techniques such as the trans-cerebellomedullary fissure approach and its variation to the fourth ventricle, as well as the cerebellomedullary cistern, infratentorial lateral supracerebellar approach to the fifth cranial nerve in the upper cerebellopontine angle, infrafloccular approach to the root exit zone of the seventh cranial nerve, transcondylar fossa approach through the lateral part of the foramen magnum, and the stitched sling retraction technique utilized during microvascular decompression procedures for trigeminal neuralgia and hemifacial spasm. It also describes in detail the bridging veins of the posterior fossa, especially the petrosal vein, and bridging veins to the tentorial sinuses, which can block approaches to the affected area. Each chapter begins with an anatomical description of the posterior fossa, after which the respective surgical approaches are explained in an easy-to-follow manner. The original Japanese version of this work was published 8 years ago, and has established itself as a trusted guide, especially among young neurosurgeons who need to study various surgical approaches and techniques. In the course of being translated into English, some sections have been revised and new information has been added. The author hopes that the book will help neurosurgeons around the world perform safer operations with confidence.
David and Goliath, the call of Samuel, the witch of Endor, David and Bathsheba — such biblical stories are well known. But the books of 1 and 2 Samuel, where they are recorded, are among the most difficult books in the Bible. The Hebrew text is widely considered corrupt and sometimes even unintelligible. The social and religious customs are strange and seem to diverge from the tradition of Moses. In this first part of an ambitious two-volume commentary on the books of Samuel, David Toshio Tsumura sheds considerable light on the background of 1 Samuel, looking carefully at the Philistine and Canaanite cultures, as he untangles the difficult Hebrew text.
Many serious accidents have happened in the world where systems have been large-scale and complex, and have caused heavy damage and a social sense of instability. Furthermore, advanced nations have almost ?nished public inf- structureandrushedintoamaintenanceperiod.Maintenancewillbemore- portant than production, manufacture, and construction, that is, more ma- tenance for environmental considerations and for the protection of natural resources. From now on, the importance of maintenance will increase more and more. In the past four decades, valuable contributions to maintenance policies in reliability theory have been made. This book is intended to s- marize the research results studied mainly by the author in the past three decades. The book deals primarily with standard to advanced problems of main- nance policies for system reliability models. System reliability can be mainly improved by repair and preventive maintenance, and replacement, and rel- bility properties can be investigated by using stochastic process techniques. The optimum maintenance policies for systems that minimize or maximize appropriate objective functions under suitable conditions are discussed both analytically and practically. The book is composed of nine chapters. Chapter 1 is devoted to an int- duction to reliability theory, and brie?y reviews stochastic processes needed for reliability and maintenance theory. Chapter 2 summarizes the results of repair maintenance, which is the most basic maintenance in reliability. The repair maintenance of systems such as the one-unit system and multiple-unit redundant systems is treated. Chapters 3 through 5 summarize the results of three typical maintenance policies of age, periodic, and block replacements.
Second Samuel includes some of the most well-known and theologically layered episodes in the Old Testament, such as the Lord’s establishment of an eternal covenant with David, David’s sin with Bathsheba, and the subsequent account of Absalom’s rebellion. In this second part of an ambitious two-volume commentary on the books of Samuel, David Toshio Tsumura elucidates the rich text of 2 Samuel with special attention to literary and textual issues. Tsumura interprets the book in light of the meaning of the original composition, and he provides a fresh new translation based on careful analysis of the Hebrew text.
This first book on high-speed atomic force microscopy (HS-AFM) is intended for students and biologists who want to use HS-AFM in their research. It provides straightforward explanations of the principle and techniques of AFM and HS-AFM. Numerous examples of HS-AFM studies on proteins demonstrate how to apply this new form of microscopy to specific biological problems. Several precautions for successful imaging and the preparation of cantilever tips and substrate surfaces will greatly benefit first-time users of HS-AFM. In turn, the instrumentation techniques detailed in Chapter 4 can be skipped, but will be useful for engineers and scientists who want to develop the next generation of high-speed scanning probe microscopes for biology. The book is intended to facilitate the first-time use of this new technique, and to inspire students and researchers to tackle their own specific biological problems by directly observing dynamic events occurring in the nanoscopic world. Microscopy in biology has recently entered a new era with the advent of high-speed atomic force microscopy (HS-AFM). Unlike optical microscopy, electron microscopy, and conventional slow AFM, it allows us to directly observe biological molecules in physiological environments. Molecular “movies” created using HS-AFM can directly reveal how molecules behave and operate, without the need for subsequent complex analyses and roundabout interpretations. It also allows us to directly monitor morphological change in live cells, and dynamic molecular events occurring on the surfaces of living bacteria and intracellular organelles. As HS-AFM instruments were recently commercialized, in the near future HS-AFM is expected to become a common tool in biology, and will enhance and accelerate our understanding of biological phenomena.
