‘‘Biopolymers’’ are polymeric materials of biological origin, including globular, membrane, and fibrous proteins, polypeptides, nucleic acids, po- saccharides, lipids, etc. and their assembly, although preference to respe- ive subjects may be different among readers who are more interested in their biological significance or industrial and/or medical applications. Nevert- less, characterizing or revealing their secondary structure and dynamics may be an equally very important and useful issue for both kinds of readers. Special interest in revealing the 3D structure of globular proteins, nucleic acids, and peptides was aroused in relation to the currently active Structural Biology. X-ray crystallography and multidimensional solution NMR sp- troscopy have proved to be the standard and indispensable means for this purpose. There remain, however, several limitations to this end, if one intends to expand its scope further. This is because these approaches are not always straightforward to characterize fibrous or membrane proteins owing to extreme difficulty in crystallization in the former, and insufficient spectral resolution due to sparing solubility or increased effective molecular mass in the presence of surrounding lipid bilayers in the latter.
Toriningu-pantsu are not training pants for babies who have not yet been toilet-trained. Toreningu-pantsu are sweat pants. When you jump into a swimming pool you will get wet, but not necessarily uetto. Volleyball, which was invented in the United States, is known as bareboru in Japan, but the tennis volley was the English gentleman's pride before it was America's . A tennis volley is therefore pronounced in British style, bore, not as American bare. Oru means "all" but has a more limited usage. Bosu is often used more negatively than English boss. Many people imagine that speakers of English who study the Japanese language find their way eased by the profusion of "English words" the Japanese have borrowed. Students of the language, however, often complain that borrowed words are more problematic than the older terms in the Japanese word pool. One of the biggest problems is the lack of adequate reference materials on the terms. Many of the existing works do little more than define the terms. This book handles the problematic areas. Here a reader will find sample sentences, tips on usage, and warnings against easy-to-commit mistakes. There are fascinating studies of how certain "English" terms were coined in Japan and of what led the Japanese to redefine certain common English words. Miura examines how certain words entered Japanese, and why they became popular. He theorizes on why an unexpected pronunciation developed. In discussing the borrowed terms, the author draws on many linguistic scholars, discusses prevailing beliefs on etymology and pronunciation, and uses his own considerable experience with both English and Japanese to help the student gain control of some of the most problematic words borrowed by J apanese from English . Each of the 850 words discussed under the text's more than 350 main headings is included in a n index for quick reference. The detail and currency of the explanations contained in this book are unmatched by other books on the subject. For the student hard put to use these borrowed words, this text offers real help.
This is an introduction to electron holography, a newly developed technique for observing and measuring microscopic structures of matter and fields using the wave nature of electrons. It describes principles, experimental details, and observation examples for vortices in superconductors, the magnetic domain structure in ferromagnets, and for fundamental phenomena of quantum mechanics.
This work includes the collected interviews with the first Japanese film director to become widely known in the West when his film "Rashomon" won the top prize at the Venice Film Festival in 1951.
The Japanese Cattle industry has been undergoing major changes for the past three decades. During the 1950's and 1960's mechanized power rapidly. The process of beef industry structure change accelerated in the 1970's as medium scale feedlots came into being, regional packing plants were established, and the beef marketing system matured. Economic forces, both within and external to the industry. A major objective of this book is to test the authors’ hypothesis that beef production by Japan's cattle industry could become competitive with imported beef.
Inflammatory bowel disease (IBD) is a chronic, relapsing intestinal inflammatory condition with increasing incidence and prevalence around the world. Conventional and biological therapies have been successfully, or unsuccessfully, applied for the treatment of IBD and several new biological therapies are currently in clinical development. So far, more than 69 kinds of animal models have been established to study IBD, and they have provided significant contributions not only for understanding the mechanism of IBD but also for developing the rationale of new therapies. Although individual animal models can not fully reflect the pathogenesis of human IBD, the data from animal models—if a consensus is reached from many but not from one or few—may be used as a predictive factor of effectiveness for some biological therapies. Therefore, in this Chapter, we will discuss this possibility by comparing the data from animal models of IBD with data from some clinical trials.
This book provides a comprehensive, theory-based analysis of current issues in population economics. It addresses the most important problems caused by demographic changes using the popular overlapping generations growth model by Samuelson and Diamond. Taking into account families’ fertility decisions, it examines not only the demographic changes due to longer life expectancy but also the effects of social security policy on demography and labor supply/individual retirement behaviors. Conducting all analyses in a dynamic general equilibrium setting, the book offers a valuable theoretical reference guide in the field of population economics.
During the past few decades we have witnessed an era of remarkable growth in the field of molecular biology. In 1950 very little was known of the chemical constitution of biological systems, the manner in which information was transmitted from one organism to another, or the extent to which the chemical basis of life is unified. The picture today is dramatically different. We have an almost bewildering variety of information detailing many different aspects oflife at the molecular level. These great advances have brought with them some breath-taking insights into the molecular mechanisms used by nature for replicating, distributing and modifying biological information. We have learned a great deal about the chemical and physical nature of the macro molecular nucleic acids and proteins, and the manner in which carbohydrates, lipids and smaller molecules work together to provide the molecular setting of living systems. It might be said that these few decades have replaced a near vacuum of informa tion with a very large surplus. It is in the context of this flood of information that this series of monographs on molecular biology has been organized. The idea is to bring together in one place, between the covers of one book, a concise assessment of the state of the subject in a well-defined field. This will enable the reader to get a sense of historical perspective what is known about the field today - and a description of the frontiers of research where our knowledge is increasing steadily.
This book is a revised and up-dated translation of Denki DendOsei Sankabutsu (Electronic Conduction in Oxides) published by Shokabo in Tokyo in 1983 as the second volume of the Material Science Series, which was edited for postgraduate students by T. Suzuki, S. Chikazumi, and S. Nakajima. Since the publication of the first edition, we have witnessed the historic discovery of high-Tc superconductors by J. G. Bednorz and K. A. Müller. Tbe Shokabo edition has thus been thoroughly revised to accommodate the recent developments, and K. Nasu joined as the fourth author. The constitution of the book is as follows: After a short introductory chapter, Chap. 2 is devoted 10 a brief review of transport phenomena and electronic states in oxides. It was written by Tsuda. In Chap. 3, the electron-phonon and electron electron interaction are treated theoretically by Nasu and Yanase. Nasu discusses the present status of theoretical studies of the electron-phonon interaction in solids and Yanase explains the electron correlation. Chapter 4 treats the physics ofvarious representative oxides in detail. Sections 4. 1-5 and 4. 10 were written by Tsuda and Sects. 4. 6-9 by Siratori. This chapter is intended not as an exhaustive review of the properties of each oxide, but rather as an illustration of the concepts which have developed out of the research into transport phenomena in conductive oxides. Many of these concepts are due 10 N. F. Mott. At the end of Chap.
Until recently the low-coordinate compounds of the heavier elements of group 14 were known only as transient, unstable species which were difficult to isolate. However recent developments have led to the stabilisation of these compounds and today heavier group 14 element cations, radicals, anions, carbene analogues, alkene and alkyne analogues and aromatics have all been prepared as highly reactive, stable, fully characterizable and readily available organometallic reagents. Organometallic Compounds of Low-Coordinate Si, Ge, Sn and Pb describes the chemistry of this exciting new class of organometallics, with an emphasis on their major similarities and differences with the analogous species in organic chemistry. Topics covered include include the synthesis, structure, reactions and synthetic applications of : Si-, Ge-, Sn and Pb-centered cations, radicals and anions heavy analogues of carbenes: silylenes, germylenes, stannylenes and plumbylenes heavy analogues of alkenes: disilenes, digermenes, distannenes, diplumbenes heavy analogues of alkynes: disilynes, digermynes, distannynes, diplumbynes, and their valence isomers heteronuclear derivatives: silenes, germenes, stannenes, silagermenes, silastannenes, germastannenes heavy analogues of alkenes of the type: >E14=E13-, >E14=E15-, >E14=E16 [where E13, E14, E15 and E16 are elements of the groups 13, 14, 15 and 16] cyclic compounds (three-, four-, five-, and six-membered rings) heavy analogues of 1,3-dienes, allenes and other cumulenes heavy analogues of aromatic compounds; including a comparison between organometallic and organic aromaticity Organometallic Compounds of Low-Coordinate Si, Ge, Sn and Pb is an essential guide to this emerging class of organometallic reagents for researchers and students in main group, organometallic, synthetic and silicon chemistry
During recent years, major advances in surgical techniques, diagnostic methods, anesthesia and adjunctive treatment in the care of patients with subarachnoid hemorrhage have been achieved. Nevertheless, the overall outcome of patients with SAH cannot be regarded as satisfactory. The first part of the book concentrates on the pathogenetic mechanisms underlying vasospasm and edema, the principal causes of poor outcome. Recent progress in the field of membrane lipid metabolism has allowed the problem to be approached from an entirely new perspective. The possible participation of free radicals, membrane lipids and eicosanoids is thoroughly discussed. The second part features the problems of practical management of SAH patients. Timing and indication of surgery of aneurysms and the surgical techniques are described in detail.
This book provides a comprehensive overview of the development of the human central nervous system (CNS) in the context of its many developmental disorders due to genetic, environmental and hypoxic/ischaemic causes. The book contains three general, introductory chapters in which an overview of the development of the human brain and spinal cord, a summary of mechanisms of development as obtained in experimental studies in various invertebrates and vertebrates, and an overview of the causes of congenital malformations are presented. The developmental disorders of the human brain and spinal cord are presented in a regional, more or less segmental way, starting with neurulation and neural tube defects, and ending with developmental disorders of the cerebral cortex. These chapters are abundantly illustrated in colour with carefully chosen clinical case studies with imaging data, and when available, postmortem verification of the developmental disorders involved. In the third edition, more emphasis has been given to the developmental ontology based on the prosomeric approach, and fetal development. Prenatal diagnosis by ultrasound, MRI and DTI, and classifications of developmental disorders have been updated. A number of new Clinical Cases have been included. Several new co-authors participate in various chapters. The book is intended for advanced medical students, and all those clinicians working with children and adults with developmental disorders of the CNS. Unique to the book is the integration of data from human embryology, experimental and molecular findings in mice in particular, imaging and developmental neuropathology.
