This eBook teaches adhesive and sealant formulation in two steps. Each section first describes the application and chemical basis of the type of adhesive or sealant concerned. This is followed by formulation advice and - if possible - an analysis of existing recipes. This analysis includes a calculation of the important characteristic values of the formulations. All calculations based on recipes and formulations are worked through step by step and should therefore be intelligible to beginners, too.

Determining the presence of different types of toxic compounds (or xenobiotics) in food requires precise analytical methodologies. Examples of these techniques include separation techniques coupled to mass spectrometry, Variations in methods used depend on the physicochemical properties of each xenobiotic being tested for.Advances in the Determination of Xenobiotics in Foods explains recent developments in the field of xenobiotic determination in food. Readers are introduced to xenobiotic testing techniques through extensive reviews. Chapters also cover details about contaminants coming from food contact materials (such as plasticizers, food additives, polymer monomers/oligomers and non-intentionally added substances), substances used for food processing and sensing (nanoparticles), and residues of pesticides (that can also be present in the final food product). The book also includes information about specific xenobiotics that, due to their global distribution in the environment, are also likely to enter the food chain. Some of them are regulated (persistent organic pollutants and heavy metals) but there are many other types of contaminants (halogenated flame-retardants, perfluorinated compounds and micro- and nanoplastics) that must also be controlled. In addition, some xenobiotics could be present in the final food consumed because of food treatments (acrylamide, furan, heterocyclic aromatic amines, and glycidol esters). Finally, the concluding chapters of the book are devoted to the presence of natural contaminants such as mycotoxins and biogenic amines.The combination of extensive information of analytical techniques for xenobiotics along with a categorical treatment of food contaminants makes this volume a handy reference for food science and technology students and technicians involved in food safety and processing management roles.

When environmental conditions deviate from the optimal range, stress ensues. Stress response is a set of reactions that allow the organism to adjust and survive adverse conditions. Stress can be physical, such as extreme temperature, radiation, injury, or psychological, caused by perceived danger or deprivation. Every living cell has biochemical mechanisms to cope with physical stress. These mechanisms show a degree of similarity among several types of living organisms. Stress Response and Immunity: Links and Trade Offs explores the functional and evolutionary connections between stress response and immunity. The book introduces the reader to the concept of stress and subsequently examines the connection between stress response and immunity at various evolutionary stages of living organisms - from bacteria to humans. The book also features chapters dedicated to the role of tumor suppressor genes and the immune system of the brain. The information presented in this reference demonstrates the profound effects of physical and psychological stress on human health. Readers with basic knowledge of molecular biology will learn about the interesting facets of stress responses and the evolutionary trade offs observed in different life forms.

Stem cell and regenerative medicine research is an important area of clinical research which promises to change the face of medicine as it will be practiced in the years to come.

Since ancient times, yeasts have been used for brewing and breadmaking processes. They now represent a flagship organism for alcoholic fermentation processes. The ubiquity of some yeast species also offers microbiologists a heterologous gene-expression platform, making them a model organism for studying eukaryotes. Yeasts: from Nature to Bioprocesses brings together information about the origin and evolution of yeasts, their ecological relationships, and the main taxonomic groups into a single volume. The book initially explores six significant yeast genera in detailed chapters. The book then delves into the main biotechnological processes in which both prospected and engineered yeasts are successfully employed. Yeasts: from Nature to Bioprocesses, therefore, elucidates the leading role of these single-cell organisms for industrial microbiology in environmental, health, social, and economic terms. This book is a comprehensive, multidisciplinary resource for general readers as well as scholars of all levels who want to know all about yeast microbiology and their industrial applications.

Regional bird field guides are few and far between in South Australia and Chris Baxters photographic guide to the birds of Kangaroo Island is the stand-out in this genre. This comprehensive account covers all 267 bird species recorded on the Island or offshore over the seas. It builds on the annotated list produced by the same author in 1989 and revised in 1995. The photographs provided by some of Australias most highly regarded photographers beautifully illustrate the detailed descriptions of the birds, their habits, habitats, breeding, status, abundance and distribution on the Island. In addition there are recommendations on where to look for each species, with cautions about not getting too close to endangered birds and their nests. Chris Baxter has called on a lifetime of bird watching on Kangaroo Island and observations from visitors and residents to present an attractive field guide that is a must for all birdwatchers from casual observers to serious ornithologists.

Based on palaeoecological studies by many authors, this book gives an overview of the changing history of the European plant cover during the past 2.6 million years, characterized by numerous cold and warm periods. The period of the last 20 000 years (from the Last Glacial Maximum to the present) is presented in detail, with special emphasis on the vegetation dynamics of Europe, the history of selected woody plants, the development of lakes and bogs and the emergence of European cultural landscapes under the influence of humans over thousands of years.In the analysis of the glacial and interglacial periods, the focus is on the different vegetation developments and the progressive impoverishment of the European flora. Further important topics are the spatio-temporal patterns and causes of long-term vegetation changes, the legacies of disturbances and land use on vegetation composition, the role of palaeoecology in nature conservation and its contribution to ecology and environmental sciences. In addition to recent research results, the book provides an overview of the main palaeoecological research methods. It concludes with a summary of the history of palaeoecology and Quaternary botany.For the first time, a detailed synthesis is presented of the many findings on European vegetation dynamics, which are complex and increasingly difficult to summarize. Numerous figures and tables, many of them original, accompany the text. The bibliography includes over 3000 publications. This book is primarily intended for students, researchers and practitioners in plant ecology, palaeoecology, palaeoclimatology, forestry, agronomy, Quaternary sciences, climate sciences, biogeography, geography and archaeology.

This book describes nuclear magnetic resonance (NMR) methods which are used to study translational dynamics of molecules in different complex systems including systems made of synthetic and natural polymers, tissues and the porous heterogeneous systems of different types, such as cement and wood. The results of proton spin-lattice and spin-spin relaxation, cross-relaxation, pulse field gradient (PFG) NMR in studying diffusion properties and dynamics of molecules in polymer systems of different complexity are reported. In addition to these methods, reports on the use of the double-quantum-filtered (DQF) NMR technique in a study of slow molecular dynamics and properties of systems with anisotropic properties, such as water in hardening cement pastes, are presented. The book also covers applications of one and two dimensional NMR techniques.This book is a useful reference for readers learning different NMR techniques and their applications in civil engineering and biochemistry.
