Book Description
Ultraviolent (UV) radiation represents a comparatively small part of the total electromagnetic spectrum, yet this portion of the spectrum is responsible for an extremely wide range of effects in many different settings. In biological systems, it can produce good and bad outcomes. We use UV radiation to drive chemical reactions that are desired, and we know that it also drives environmental reactions that are harmful to living organisms. We use UV radiation to interrogate molecules and to analyze cells. Some animals view our world in the UV radiation range, while astronomers use UV to study the universe; in both cases, what is observed is very different from that observed using other parts of the electromagnetic spectrum. This volume gives the reader just the very beginning of the broad range of properties, applications, and effects of UV radiation and is intended to stimulate the reader to explore more of this fascinating part of the electromagnetic spectrum.

Book Description
This detailed, comprehensive book describes the fundamental properties of soft X-rays and extreme ultraviolet (EUV) radiation and discusses their applications in a wide variety of fields, including EUV lithography for semiconductor chip manufacture and soft X-ray biomicroscopy. The author begins by presenting the relevant basic principles such as radiation and scattering, wave propagation, diffraction, and coherence. He then goes on to examine a broad range of phenomena and applications. The topics covered include spectromicroscopy, EUV astronomy, synchrotron radiation, and soft X-ray lasers. The author also provides a wealth of useful reference material such as electron binding energies, characteristic emission lines and photo-absorption cross-sections. The book will be of great interest to graduate students and researchers in engineering, physics, chemistry, and the life sciences. It will also appeal to practising engineers involved in semiconductor fabrication and materials science.

Book Description
The Biological Action of Physical Medicine: Controlling the Human Body's Information System challenges the contemporary way of thinking of diagnostics and therapy "from the outside." Drawing on 30 years of independent comprehensive research, this reference provides a universal and scientifically acceptable physiological theory, explaining the mode of action of methods of physical medicine as well as the underlying physiological mechanisms. Scientific research described in this book explains the universal neurophysiological foundation of all the respective methods, including organ electrodermal diagnostics (OED), thermotherapy (heat, cryostimulation), phototherapy (infrared, ultraviolet, laser), ultrasound therapy, electrotherapy (from transcutaneous electric nerve stimulation to electromagnetic field therapies), magnetotherapy, and mechanical nerve stimulation (acupuncture, reflexive massage, cupping, high-pressure hydrotherapy). A better understanding of physical medicine's modes of action not only insures better clinical results, but also illuminates pain mechanisms and our understanding of the functioning of the nervous system. - Fully explains the important therapeutic modalities of genuine physical medicine as well as the underlying physiological mechanisms - Shows how to access and control the diagnostic information circulating in the sensory nervous system

Book Description
Bioresorbable materials are extensively used for a wide range of biomedical applications from drug delivery to fracture fixation, and may remain in the body for weeks, months or even years. Accurately predicting and evaluating the degradation rate of these materials is critical to their performance and the controlled release of bioactive agents. Degradation rate of bioresorbable materials provides a comprehensive review of the most important techniques in safely predicting and evaluating the degradation rate of polymer, ceramic and composite based biomaterials.Part one provides an introductory review of bioresorbable materials and the biological environment of the body. Chapters in Part two address degradation mechanisms of commonly used materials such as polymers and ceramics. This is followed by chapters on bioresorption test methods and modelling techniques in Part three. Part four discusses factors influencing bioresorbability such as sterilisation, porosity and host response. The final section reviews current clinical applications of bioresorbable materials.With its distinguished editor and multidisciplinary team of international contributors, Degradation rate of bioresorbable materials: prediction and evaluation provides a unique and valuable reference for biomaterials scientists, engineers and students as well as the medical community. - Comprehensively reviews the most pertinent techniques in safely predicting and evaluating the degradation rate of bioresorbable materials - Addresses degradation mechanisms of commonly used materials - Discusses factors influencing bioresorbability such as sterilisation and host response

Book Description
Wood Coatings addresses the factors responsible for the performance of wood coatings in both domestic and industrial situations. The term 'wood coatings' covers a broad range of products including stains, varnishes, paints and supporting ancillary products that may be used indoors or outdoors. Techniques for coating wood go back many centuries but in recent decades there has been a move towards more environmentally-friendly materials, for example, the use of water-borne rather than solvent-borne chemicals. A major objective of Wood Coatings is to explain the underlying factors that influence selection, application and general operational issues. Basic information on the chemistry and technology of coatings is included for the benefit of students and laboratory technicians. Additionally, the book includes individual chapters of interest to architects, specifiers, and industrial users. - Offers up-to-date guidance on current availability and usage of wood coatings - Provides the reader with a basic understanding of both coating and substrate interactions - Covers both architectural (trade and DIY) and industrial sectors

Book Description
UV light is one of a number of emerging non-thermal food processing technologies that can be used in a broad range of applications producing food products with longer shelf-life, more safe, and with higher nutritional quality. The new edition of Ultraviolet Light in Food Technology: Principles and Applications will present recent understanding of the fundamentals of UV light along with new applied knowledge that has accumulated during the 7 years since the first edition published in 2009. The new edition of the book will have 11 chapters including 2 new chapters--on chemical destruction with UV light and food plant safety—along with 6 chapters greatly expanded and updated.

Book Description
Tumors can be induced by a variety of physical and chemical carcinogens. The resulting tumor cells are usually abnormal in their morphology and behavior and transmit their abnormalities to their daughter tumor cells. Most theories of the pathogenesis of tumors suggest that carcinogens in some way cause alterations either of the genomes or of inheritable patterns of gene expression in normal cells, which then cause morphological and behavioral changes. This volume presents a collection of articles aimed at the question by what genetic or epigenetic mechanisms carcinogens can cause morphological abnormalities of tumor cells. It includes reviews of cellular targets of known carcinogens, and presents varying viewpoints of how morphological abnormalities and the actions of carcinogens might be related. The volume will be of interest to all those who are involved in cancer research or in the prevention, diagnosis or management of tumors in humans or animals.

Book Description
The Mosaic of Autoimmunity: The Novel Factors of Autoimmune Diseases describes the multifactorial origin and diversity of expression of autoimmune diseases in humans. The term implies that different combinations of factors in autoimmunity produce varying and unique clinical pictures in a wide spectrum of autoimmune diseases. Most of the factors involved in autoimmunity can be categorized into four groups: genetic, immune defects, hormonal and environmental factors. In this book, the environmental factors are reviewed, including infectious agents, vaccines as triggers of autoimmunity, smoking and its relationship with rheumatoid arthritis, systemic lupus erythematosus, thyroid disease, multiple sclerosis and inflammatory bowel diseases. An entirely new syndrome, the autoimmune/inflammatory syndrome induced by adjuvants (ASIA), is also included, along with other diseases that are now recognized as having an autoimmune etiopathogenesis.
