This book covers designing of various machine elements and serves as a reference for mechanical designing of machine elements in academia and industry. It provides information on designing approaches and several examples and problems, enabling readers to make all of their required calculations for their specific mechanical design or fabrication tasks by using the book's plots (graphs), instead of complicated formulas.

"Trace metals are necessary for the proper functioning of living organisms and are absorbed by the body through diet or environmental exposure. However, excessive intake of trace metals can cause health problems. As such, the study of the presence of trace metals in the environment and their effects on health is important. This volume includes four chapters that provide details about trace metals in various contexts. Chapter One explains the nutritional zinc requirements of humans and discusses the usefulness of different supplements in various applications. Chapter Two addresses the different aspects of metal-microbial interactions, focusing on soil and sediment ecosystems. Chapter Three addresses pollution of heavy metals, emission sources, health implications, and commonly used methods for assessment of pollution. Lastly, Chapter Four assesses possible changes in the geochemical behavior of chromium caused by sediment resuspension in a hypereutrophic estuary that receives domestic and industrial effluents daily"--

"Porous Carbons: Syntheses and Applications focuses on the fabrication and application of porous carbons. It considers fabrication at three scales: micropores, mesopores, and macropores. Carbon foams, sponges, and 3D-structured carbons are detailed. The title presents applications in four key areas: energy storage, energy conversion, energy adsorption, including batteries, supercapacitors, and fuel cells and environmental remediation, emphasizing the importance of pore structures at the three scales, and the diffusion and storage of various ions and molecules. The book presents a short history of each technique and material, and assesses advantages and disadvantages. This focused book provides researchers with a comprehensive understanding of both pioneering and current synthesis techniques for porous carbons, and their modern applications."--

"Clinical Signs in Humans and Animals Associated with Minerals, Trace Elements and Rare Earth Elements is the first book to compile the clinical signs associated with deficiencies, toxicities, imbalances, exposures to minerals, trace elements and rare earth elements in animals. This book aims to increase awareness to improve diagnosis and to encourage further investigation based on comparative data. Written by an experienced veterinary clinician having worked in private practice, academia, pharmaceutical and pet food industries, this book includes data on companion animals, horses, rabbits, reptiles, ruminants, poultry, fish, and species typical in zoo populations. In addition, the book touches upon human and other primate data. The subject material is divided into three sections to provide easy access to information on clinical signs, specific elements, or species. This is an ideal resource for veterinary researchers, clinicians and practitioners, specifically those working with animal nutrition and animal feed health. Academics and public health scientists will also benefit from this book's information and data on rehabilitating and maintaining animal health"-- |c Provided by publisher.

Hazardous and Trace Materials in Soil and Plants: Sources, Effects and Management explores the latest advancements in reducing, avoiding and eliminating soil contaminants that challenge the health and safety of agricultural plants. With a focus on minimizing the production of those hazardous substances, controlling their distribution and ensuring safe utilization, the book explores each contributing area and provides insights toward improved, sustainable and secure production. This is an excellent reference resource on both current research and future directions from laboratory research to field applications.The combined impacts of climate change and industrialization have led to increased and diversified threats to the health of the soil in which our food crops are grown, as well as in the plants themselves. This dual-hazard scenario is increasingly recognized as a threat to not just the environment, but to global food security as agricultural soils contaminated with pollutants alter plant metabolism, thus resulting in reduced crop quality and production quantity.

150 years ago, in 1869, D. I. Mendeleev and L. Meyer independently published their ideas on the arrangement of the chemical elements in a periodic system. The United Nations and UNESCO therefore declared 2019 the "International Year of the Periodic Table". The question arises, what is so special about this "simple table"? Join the author on a short journey to the history of the periodic table. Learn about its predecessors and look at how the periodic table of elements has evolved over the years. Discover the periodic properties of the elements. Learn what makes the periodic table so interesting and timeless, and see what other ideas there are and have been for representing it. The content Atomic theories, atomic structure and atomic masses Early attempts to systematize the elements Mendeleev's periodic table and periodicities of the elements Alternative periodic systems The target groups Students and lecturers of chemistry, especially history of chemistry Teachers and students as well as those interested in the history of chemistry The author Torsten Schmiermund has been working as a chemical technician in the chemical industry for many years. This book is a translation of an original German edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.

Vapor Generation Techniques for Trace Element Analysis: Fundamental Aspects provides an overview and discussion of the fundamental aspects governing derivatization reactions of trace-level elements for analytical purposes. Vapor generation techniques coupled with atomic or mass spectrometry have been employed for over 50 years, but their popularity has dramatically increased in recent years, especially as alternative vapor generation approaches have been developed. This book bridges the knowledge gap of the derivatization mechanisms that yield volatile compounds and provides an update on recent developments in vapor generation techniques used for the determination and speciation of trace elements by atomic optical and mass spectrometry. It will serve as a comprehensive, single-source overview of recent developments, providing readers with an understanding of the correct implementation—and limitations—of applying vapor generation techniques to everyday analytical problems facing the trace element analyst.
