Book Description
This updated and expanded edition presents a highly accurate specification for part surface machining. Precise specification reduces the cost of this widely used industrial operation as accurately specified and machined part surfaces do not need to undergo costly final finishing. Dr. Radzevich describes techniques in this volume based primarily on classical differential geometry of surfaces. He then transitions from differential geometry of surfaces to engineering geometry of surfaces, and examines how part surfaces are either machined themselves, or are produced by tools with surfaces that are precisely machined. The book goes on to explain specific methods, such as derivation of planar characteristic curves based on Plücker conoid constructed at a point of the part surface, and that analytical description of part surface is vital for surfaces machined using CNC technology, and especially so for multi-axes NC machines. Providing readers with a powerful tool for analytical description of part surfaces machined on conventional machine tools and numerically controlled machines, this book maximizes understanding on optimal treatment of part surfaces to meet the requirements of today’s high tech industry.

Book Description
FROM THE PREFACE The surface modification of polymeric materials has been the object of a large number of investigations, but little attention has been paid to making a polymer surface frictionless or slippery, and lubricating surfaces are practically unmentioned in any books so far published, probably because of the relatively minor importance of polymer friction in industrial applications. A lubricating polymer surface is important, especially in marine and biomedical technologies. For instance, biomaterials to be used for catheterization on the urinary, tracheal, and cardiovascular tracts, or for endoscopy, should have a surface with good handling characteristics when dry and which preferably becomes slippery upon contact with body liquids. Such a low-friction surface must enable easy insertion and removal of the device from a patient. It would further prevent mechanical injury to the mucous membranes and minimize discomfort to the patient. Earlier approaches to providing a low-friction surface were mostly simple applications involving lubricants such as lidocaine jelly, silicone oil, or non-permanent coating with low-friction materials such as polyethylene or fluoroplastics. However, these substances cannot maintain a high degree of slipperiness for the required duration of time, due to the fact that they leach or disperse into the surrounding body fluids. The aim of this book is to describe the principle of lubrication, to outline a variety of methods for attaining a lubricous surface, and to describe the characteristics and properties of such lubricous surfaces. The technology for surface modification of polymers by grafting will find other applications than for lubrication, such as for improvement of the interfacial adhesion in polymer composites.

Book Description
The boreal forest is the northern-most woodland biome, whose natural history is rooted in the influence of low temperature and high-latitude. Alaska's boreal forest is now warming as rapidly as the rest of Earth, providing an unprecedented look at how this cold-adapted, fire-prone forest adjusts to change. This volume synthesizes current understanding of the ecology of Alaska's boreal forests and describes their unique features in the context of circumpolar and global patterns. It tells how fire and climate contributed to the biome's current dynamics. As climate warms and permafrost (permanently frozen ground) thaws, the boreal forest may be on the cusp of a major change in state. The editors have gathered a remarkable set of contributors to discuss this swift environmental and biotic transformation. Their chapters cover the properties of the forest, the changes it is undergoing, and the challenges these alterations present to boreal forest managers. In the first section, the reader can absorb the geographic and historical context for understanding the boreal forest. The book then delves into the dynamics of plant and animal communities inhabiting this forest, and the biogeochemical processes that link these organisms. In the last section the authors explore landscape phenomena that operate at larger temporal and spatial scales and integrates the processes described in earlier sections. Much of the research on which this book is based results from the Bonanza Creek Long-Term Ecological Research Program. Here is a synthesis of the substantial literature on Alaska's boreal forest that should be accessible to professional ecologists, students, and the interested public.

Book Description
Electrons, Neutrons and Protons in Engineering focuses on the engineering significance of electrons, neutrons, and protons. The emphasis is on engineering materials and processes whose characteristics may be explained by considering the behavior of small particles when grouped into systems such as nuclei, atoms, gases, and crystals. This volume is comprised of 25 chapters and begins with an overview of the relation between science and engineering, followed by a discussion on the microscopic and macroscopic domains of matter. The next chapter presents the basic relations involving mechanics, electricity and magnetism, light, heat, and related subjects which are most significant in the study of modern physical science. Subsequent chapters explore the nucleus and structure of an atom; the concept of binding forces and binding energy; the configuration of the system of the electrons surrounding the atomic nucleus; physical and chemical properties of atoms; and the structure of gases and solids. The energy levels of groups of particles are also considered, along with the Schrödinger equation and electrical conduction through gases and solids. The remaining chapters are devoted to nuclear fission, nuclear reactors, and radiation. This book will appeal to physicists, engineers, and mathematicians as well as students and researchers in those fields.

Book Description
Architecture is defined by its materials and surfaces. Not infrequently, it is their look and feel that determine whether a project succeeds or fails. For this reason, it is crucially important that planners choose the right materials and use them correctly, a task that is especially challenging today, when they are confronted with an almost dizzying variety of design possibilities and almost unlimited industrial production techniques. In Detail: Materials for Interiors provides detailed and specific information on the use of appropriate materials in interior design. The book leads off with an overview of the range of available products for interior design, including large-format photographs of each material and interiors that use them. This is followed by detailed discussions of relevant aspects and production methods of the individual material groups, including selected examples. The processing of the materials is illustrated by production photographs from the construction site and numerous detail drawings. In the accompanying texts, expert planners who specialize in the various materials share their practical knowledge of how to use them. The technical articles and example projects focus on the surface of the material and how it is produced or comes to be and contain corresponding decision support for planners. Additional technical information on the materials used and a list of manufacturer and vendor addresses round out the volume. Werkstoffe und Oberflächen prägen die Architektur. Nicht selten entscheiden deren Optik und Haptik über Erfolg oder Misserfolg eines Projektes. Umso mehr stellt die richtige Auswahl und Verwendung von Materialien für den Planer eine besondere Herausforderung dar, der heutzutage – besonders im Innenausbau – einer nahezu unübersichtlichen Vielfalt an Gestaltungsmöglichkeiten und nahezu uneingeschränkten industriellen Fertigungstechniken gegenübersteht. „Im Detail: Material im Innenraum" liefert gezielte und detaillierte Informationen zum Einsatz geeigneter Materialien im Innenausbau. Den Auftakt des Buches bildet ein Überblick über die Produktpalette beim Innenausbau mit einem großformatigen Fotos des jeweiligen Materials und eines damit ausgestatteten Innenraums. Planungsrelevante Aspekte und Fertigungsmethoden der einzelnen Materialgruppen werden dann anhand ausgewählter Beispiele detailliert erläutert. Die Verarbeitung der Werkstoffe wird durch Fertigungsfotos von der Baustelle und mit zahlreichen Detailzeichnungen veranschaulicht. Die Begleittexte vermitteln das Praxiswissen von den jeweiligen Fachplanern zum Einsatz der Werkstoffe. Der Schwerpunkt der Fachartikel und der Projektbeispiele liegt dabei auf der Materialoberfläche, deren Entstehungs- bzw. Herstellungsprozess und birgt entsprechende Entscheidungshilfen für die Planung. Zusätzliche technische Infos zu den verwendeten Materialien sowie Hersteller/Bezugsadressen runden das Buch ab.

Book Description
In this book, the author determines that a surface is itself a new material for chemical reaction, and the reaction of the surface provides additional new materials on that surface. The revelation of that peculiarity is what makes this book different from an ordinary textbook, and this new point of view will help to provide a new impetus when graduate students and researchers consider their results. The reaction of surface atoms provides additional new compounds, but these compounds cannot be detached from the surface. Some compounds are passive, but others work as catalysts. One superior feature of the surface is the dynamic cooperation of two or more different functional materials or sites on the same surface. This fact has been well established in the preferential oxidation of CO on platinum supported on a carbon nanotube with Ni-MgO at its terminal end. The Pt and Ni-MgO are perfectly separated, but these two are indispensable for the selective oxidation of CO in H2, where the H2O molecule plays a key role. The reader will understand that the complexity of catalysis is due to the complexity of the dynamic processes on the surface.
