Book Description
Presents a new physical and mathematical theory of irreversible deformations and ductile fracture of metals that acknowledges the continuous change in the structure of materials during deformation and the accumulation of deformation damage. Plastic deformation, viscous destruction, evolution of structure, creep processes, and long-term strength of metals and stress relaxation are described in the framework of a unified approach and model. The author then expands this into a mathematical model for determining the mechanical characteristics of quasi-samples of standard mechanical properties in deformed semi-finished products.

Book Description
US-Japan meetings on laboratory animal science have been held virtually every year since 1980 under the US-Japan Cooperative Program on Science and Technology. Over the years these meetings have resulted in a number of important documents including the Manual of Microbiologic of Monitoring of Laboratory Animals published in 1994 and the article Establishment and Preservation of Reference Inbred Strains of Rats for General Purposes published in 1991. In addition to these publications, these meetings have been instrumental in increasing awareness of the need for microbiologic monitoring of laboratory rodents and the need for genetic definition and monitoring of mice and rats.

Book Description
The steady increase in computational power induces an equally steady increase in the complexity of the engineering models and associated computer codes. This particularly affects the modeling of the mechanical response of materials. Material behavior is nowadays modeled in the strongly nonlinear range by tak ing into account finite strains, complex hysteresis effects, fracture phenomena and multiscale features. Progress in this field is of fundamental importance for many engineering disciplines, especially those concerned with material testing, safety, reliability and serviceability analyses of engineering structures. In recent years many important achievements have been made in the field of the theoretical formulation, the mathematical analysis and the numerical im plementation of deformation processes in solids. Computational methods and simulation techniques today play a central role in advancing the understanding of complex material behavior. Research in the field of "ComputationalMechan ics of Materials" is concerned with the development of mathematical models and numerical solution techniques for the simulation of material response. It is a very broad interdisciplinary field of science with inputs from traditional fields such as Applied Mechanics, Applied Mathematics, Materials Science, Solid State Physics and Information Technology. The intention of the IUTAM Symposium "Computational Mechanics of Solid Materials at Large Strains", held at the University of Stuttgart, Germany, from August 20-24, 200I, was to give a state of the art and a survey about recent developments in this field and to create perspectives for future research trends.

Book Description
The strict relationships between bacteria and plants represents one of the major facets of terrestrial ecology. Depending on the type of interaction and amount of metabolic advantage one organism can obtain from such relationships, these are classified as mutualistic, commensal or parasitic interactions. Within this context, Pseudomonas and Xanthomonas are bacterial genera with a worldwide spread, capable of establishing all of the above mentioned interactions with plants. Therefore, they represent good models for studying different lifestyles and, accordingly, deciphering distinct evolutionary trajectories followed by different lineages of a single genus to infect and/or to establish a mutualistic relationships with the plant. Some members of these two genera are regulated pests that are recognized as economically major threats for their host crop(s) both in temperate and tropical environments.

Book Description
Until about 10 years ago, the general view in the field was that Mycobacterium tuberculosis, the causative agent of human tuberculosis was a “clone” with insufficient natural sequence variation between clinical strains to be considered biologically and epidemiologically “relevant”. This view has now changed quite dramatically thanks to the –omics revolution, particularly the advent of next generation DNA sequencing. Large-scale comparative genomic studies over the last few years have revealed that M. tuberculosis clinical strains are more genetically diverse than appreciated previously. Moreover, an increasing number of experimental and epidemiological studies are showing that this genetic diversity also translates into important phenotypic variation. Taken together, these findings have led to a paradigm shift, such that currently phylogenetic diversity among M. tuberculosis clinical strains is being considered in the development of new tools to combat tuberculosis. The purpose of this book is to bring together a series of contributions from some of the most influential groups working on various aspects of M. tuberculosis diversity, and which through their work have contributed to the this paradigm shift. This includes authors focusing on the evolution of M. tuberculosis in relation to other members of the M. tuberculosis complex adapted to animals, the co-evolution between M. tuberculosis and humans, the phenotypic consequences of strains diversity both from an experimental and epidemiological point of view, the ecology and evolution of drug resistant tuberculosis, the diversity and evolution of the BCG vaccine strains, and the use of mathematical modelling to study strain diversity and drug resistance in human tuberculosis. No such book has ever been published, and given the paradigm shift described above, this book will be a valuable resource both for established researchers as well as new scientists, clinicians and public health officials joining the growing field of tuberculosis research.

Book Description
Charts are presented for rapidly determining the principal strains and stresses, the maximum shear strain and stress, and the orientation of principal axes for data for 45 degrees strain rosettes. The charts may be used for analyzing the conventional data consisting of strains measured along three gage lines 45 degrees apart, but their application is more direct if the rosette data are obtained by means of special circuits that require the use of four gages 45 degrees apart.

Book Description
This book highlights current trends and developments in the area of engineering strains. The book details the current and future tools used in the production of bulk chemicals and biofuels from renewable biomass using green technologies. Complex phenotypes are traits in a microbe that requires multiple genetic changes to be modulated simultaneously in the microorganism’s DNA. Knowing what those genetic changes are for a given trait and how to make those changes in the most efficient way forms the motivation behind writing this book. This book explains the newer tools to develop and enable engineered strains at time scales much faster that the natural evolution process so that we can increase a cells' production of a certain substance, increase process productivity, and extend metabolic capability. This book provides a one stop platform of reference for practicing researchers in the field of industrial biotechnology. This book also explains that the commercial success of a process that uses microbial catalysts over platforms that use chemical catalysts and fossil fuels depends on the time it takes to engineer these microbes to perform the desired reaction under harsh manufacturing conditions and at rates that meets the criteria for economic feasibility.

Book Description
Actinobacteria are well-known producers of a vast array of secondary metabolites. Compared with actinobacteria from temperate habitats, the community structure, diversity, biological activities and mechanisms of environmental adaptation of those actinobacteria in special and extreme environments are relatively unstudied and unclear, and their functions and utilization are even less reported. These actinobacteria are potential new sources of novel natural products and functions for exploitation in medicine, agriculture, and industry. Recent advances in cultivation, DNA sequencing technologies and -omics methods have greatly contributed to the rapid advancement of our understanding of microbial diversity, taxonomy, function and they interactions with environment. Following the success of the Research Topic “Actinobacteria in special and extreme habitats: diversity, functional roles and environmental adaptations” organized in 2015, we are happy to launch a second edition. This Research Topic second edition, comprising reviews and original articles, highlights recent discoveries on rare actinobacterial diversity, phylogenomics, biological compounds, ecological function and environmental adaptations of actinobacteria in special and extreme habitats; and broadens our knowledge of actinobacterial diversity and their ecophysiological function.
