Chemokines and Viral Infection
This edition of Current Topics in Microbiology and Immunology examines the role of chemokines and chemokine receptors in host defense and disease development following viral infection. Chemokines represent a family of over 40 small proteins that, for the most part, are secreted into the environment and function by binding to G protein-coupled receptors (GPCRs) that are expressed on numerous different cell types. When initially identified close to 30 years ago, these molecules were associated with various human inflammatory diseases and it was recognized that expression may be integral in leukocyte recruitment to inflamed tissue. There are now four sub-families of chemokines identified based on defined structural criteria relating to the positional location of conserved cysteine residues within the amino-terminus of the protein. Chemokines are now recognized as important in numerous biological processes ranging from maintaining the organizational integrity of secondary lymphoid tissue to participating in various aspects of both innate and adaptive immune responses following microbial infection. With this in mind, this book highlights the functional roles of chemokines and their receptors in participating in various aspects of the immune response against well-known viral pathogens.

Charismatic Christianity in Finland, Norway, and Sweden : Case Studies in Historical and Contemporary Developments
The history of Charismatic Christianity in the Nordic countries reaches as far back as Pentecostalism itself. The bounds of these categories remain a topic of discussion, but Nordic countries have played a vital role for developing this rapidly spreading form of world-wide Christianity. Until now, research on global Charismatic Christianity has largely overlooked the region. This book addresses and analyzes its historical and contemporary trajectories in Finland, Norway and Sweden. Through a selection of cases written by Nordic scholars from various disciplines, it demonstrates historical and contemporary diversity as well as interconnections between local, national, and global currents. Highlighting change and continuity, the anthology reveals new aspects of Charismatic Christianity.
Characterization of Corrosion Products on Steel Surfaces
It is well known that corrosion products, i.e. rust, on iron and steel surfaces cannot be assigned a typical crystallographic structure with long-range order. In fact, the structure of rust is considered to be very complicated, and some forms of rust are assigned to the amorphous state for this reason. Accurate information about the atomic-scale structure of rust is important to shed light on corrosion mechanisms of metallic materials. And, since life of steel structures is often dominated by environmental degradation or corrosion of the surface, the structure of the rust formed on iron and steel surfaces during prolonged exposure to air is of great interest. This book describes the fundamental aspects of materials characterization for the ferric oxyhydroxides formed on steel surfaces.

Cell Separation : Fundamentals, Analytical and Preparative Methods
This special volume on cell separations discusses fundamental and applied aspects of the analytical and preparative cell-separation technologies. The aim is to enlighten the reader with the new developments in cell-separation technologies and at the same time provide sufficient knowledge with other existing and more commonly used techniques. The volume is comprised of contributions from subject experts from both academia and industry, focuses on the research and commercial aspects of cell-separation technology, and provides readers with broader choice. Unlike protein separation, the major challenge in cell separation has been the recovery of the cells in viable form after they are bound to the separation matrix, as cells bind more strongly through multipoint attachment. This is an important focus of the present work and one we believe will provide new insight to researchers in this field
Cell Motility in Cancer Invasion and Metastasis
Cancer Morbidity and mortality result from invasive and metastatic spread. Currently, no therapies are aimed at the underlying mechanisms that enable this progression due to only nascent recognition of the distinct biology which occurs only during tumor dissemination. Recent advances have highlighted the central role of cell motility during the dynamic and transient process of tumor invasion and metastasis. This book includes state-of-the-art updates by international leaders in these studies. Chapters first present the novel model systems that enable new investigations and insights. Chapters then describe in depth the key processes and molecules that may be therapeutically targeted. Finally, the role of cell motility and its signals is explored in a number of key tumor types. This compilation should be useful to researchers in basic and translational oncology as well as those developing novel agents to prevent tumor invasion and metastasis.

Cell Adhesion and Cytoskeletal Molecules in Metastasis
In this volume, the expression of specific adhesion molecules within human cancer tissues are highlighted. The expression signatures from published DNA microarray and immunohistochemistry studies are detailed. The concept that the alteration of specific adhesion molecules influence the cancer migration ability and cancer damage responses is detailed in this volume; both features are essential for the survival of an invading tumor cell. Defining the minimal adhesion receptors preserved on cancer cells during tumor progression will define the metastatic adhesion signature. Understanding the metastatic adhesion signature will reveal vulnerabilities that could be exploited for the prevention and/or eradication of the invading cancer cell.

CCD Astrophotography : High-Quality Imaging from the Suburbs
This is a reference book for amateur astronomers who have become interested in CCD imaging. Those glorious astronomical images found in astronomy magazines might seem out of reach to newcomers to CCD imaging, but this is not the case. Great pictures are attainable with modest equipment. Adam Stuart’s many beautiful images, reproduced in this book, attest to the quality of – initially – a beginner’s efforts. Chilled-chip astronomical CCD-cameras and software are also wonderful tools for cutting through seemingly impenetrable light-pollution. CCD Astrophotography from the Suburbs describes one man’s successful approach to the problem of getting high-quality astronomical images under some of the most light-polluted conditions.
Catastrophic Events Caused by Cosmic Objects
Many times all of us could hear from mass media that an asteroid approached and swept past the Earth. Such an asteroid or comet will inevitably strike the planet some day. This volume considers hazards due to collisions with cosmic objects, particularly in light of recent investigations of impacts by the authors. Each chapter written by an expert contains an overview of an aspect and new findings in the field. The main hazardous effects – cratering, shock, aerial and seismic waves, fires, ejection of dust and soot, tsunami are described and numerically estimated. Numerical simulations of impacts and impact consequences have received much attention in the book. Fairly small impacting objects 50 -100 m in diameter pose a real threat to humanity and their influence on the atmosphere and ionosphere is emphasized.
Catalytic role of amino acids in organic reactions

The major reaction types of carbon monoxide are comprehensively discussed by leading experts from academia and industry. The authors highlight important carbonylation reactions such as hydroformylation, alkoxy-carbonylations, co/olefin-copolymerization, Pauson-Khand reactions and others. They illustrate applications in organic synthesis and give industrial examples.
Case-Based Approximate Reasoning
Case-based reasoning (CBR) has received a great deal of attention in recent years and has established itself as a core methodology in the field of artificial intelligence. The key idea of CBR is to tackle new problems by referring to similar problems that have already been solved in the past. More precisely, CBR proceeds from individual experiences in the form of cases. The generalization beyond these experiences typically relies on a kind of regularity assumption demanding that 'similar problems have similar solutions'. Making use of different frameworks of approximate reasoning and reasoning under uncertainty, notably probabilistic and fuzzy set-based techniques, this book develops formal models of the above inference principle, which is fundamental to CBR. The case-based approximate reasoning methods thus obtained especially emphasize the heuristic nature of case-based inference and aspects of uncertainty in CBR. This way, the book contributes to a solid foundation of CBR which is grounded on formal concepts and techniques from the aforementioned fields. Besides, it establishes interesting relationships between CBR and approximate reasoning, which not only cast new light on existing methods but also enhance the development of novel approaches and hybrid systems.
