This book describes how chronic wounds follow a completely different healing trajectory to acute wounds and discusses the factors associated with these poor healing trajectories. These factors include age, chronic inflammation, phenotypic changes in such cells as macrophages, fibroblasts, and keratinocytes, colder, alkaline wound milieu, wound related hypoxemia, and diabetes. Other factors implicated include reperfusion injury, poor patient compliance, presence of undiagnosed and therefore unmanaged biofilms and wound pain. The past decades have yielded reliable evidence-based guidelines and standardized care, but the healing of diabetic foot wounds continues to be unpredictable notwithstand...
This volume presents a short guide to the extensive literature concerning semir ings along with a complete bibliography. The literature has been created over many years, in variety of languages, by authors representing different schools of mathematics and working in various related fields. In many instances the terminology used is not universal, which further compounds the difficulty of locating pertinent sources even in this age of the Internet and electronic dis semination of research results. So far there has been no single reference that could guide the interested scholar or student to the relevant publications. This book is an attempt to fill this gap. My interest in the theory of semir...
This book shows how to prepare titania rich slag from metallized ilmenite using thermal plasma processing. The author reveals the development of a thermal plasma process alternative to the current used ones, which are highly energy costly. The appropriate design of the plasma reactor, which is crucial for achieving reduced energy consumption, is described in this book. The content can be of interest for industrial purposes.
This book provides an introduction to the algebraic theory of semirings, including a detailed treatment of some applications in theoretical computer science. The focus is on the general concepts and statements of the algebraic theory of semirings and those aspects of the theory which are needed for the aforementioned applications. The book also deals with a concept of semirings that includes commutativity of addition, as is usually done for rings.
Materials science includes those parts of chemistry and physics that deal with the properties of materials. It encompasses four classes of materials, the study of each of which may be considered a separate field: metals; ceramics; polymers and composites. Materials science is often referred to as materials science and engineering because it has many applications. Industrial applications of materials science include processing techniques (casting, rolling, welding, ion implantation, crystal growth, thin-film deposition, sintering, glassblowing, etc.), analytical techniques (electron microscopy, x-ray diffraction, calorimetry, nuclear microscopy (HEFIB) etc.), materials design, and cost/benefit tradeoffs in industrial production of materials. This book presents new research directions in a very new field which happens to be an old field as well.
The Encyclopedia of Lunar Science includes the latest topical data, definitions, and explanations of the many and varied facets of lunar science. This is a very useful reference work for a broad audience, not limited to the professional lunar scientist: general astronomers, researchers, theoreticians, practitioners, graduate students, undergraduate students, and astrophysicists as well as geologists and engineers. The title includes all current areas of lunar science, with the topical entries being established tertiary literature. The work is technically suitable to most advanced undergraduate and graduate students. The articles include topics of varying technical levels so that the top scie...
