Book Description
Nearly three thousand papers and patents are dedicated to the actual or potential uses of cyclodextrins in pharmacy and pharmaceutical formulations. This is the first book written for pharmacists and pharmaceutical technologists which not only critically summarizes the enormous amount of literature available, but which can be used as a handbook when looking for solutions to practical problems. The fundamentals -- chemistry of cyclodextrins and their derivatives -- their physical and chemical properties are condensed to the most relevant items in Chapters 1 and 2. Chapter 3 deals with the adsorption, metabolism and toxicological properties of cyclodextrins. Chapter 4 explains the formulation, structure, composition and advantageous effects of the cyclodextrin inclusion complexes. Chapter 5 describes the methods for preparation and characterization of drug/cyclodextrin complexes. Chapters 6 and 7 are dedicated to the pharmacokinetics, biopharmaceutical and technological aspects of drug/CD complexes. Chapter 8 treats the application and effects of cyclodextrins in various drug formulations. The Appendix comprises a collection of recipes for any type of drug formulation. This book is aimed at those who use cyclodextrins in drug formulations, to improve the properties of existing drug formulations, or who want to prepare quite new formulations.

Book Description
The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

Book Description
Do you want to develop useful skills, gain admission to top colleges, win scholarship money, excel at science competitions, and explore career options--all while having fun?By reading this book and using the advice within it, you will learn how to formulate a research project idea, find people who can help you complete it, effectively present it to diverse audiences, and participate successfully in research competitions. Whether you are a freshman rookie with a vague interest in science or a senior veteran striving for first place at the Science Talent Search, this guide will help you make the most of your research experience.With its testimonials from high school students whose lives were positively changed by their research experiences, this guide also aims to motivate and empower students who otherwise would not pursue science and research opportunities. In doing so, this book also seeks to encourage more students to pursue science and technology."What Shiv Gaglani and his co-authors offer with this book is a well-crafted and practical guide for any high school student who wants to participate in (and win!) the Intel Science Talent Search, Intel International Science and Engineering Fair, or any similar research endeavor. As sponsors of these programs, we regularly get requests for exactly this information from all around the globe. I am excited to be able to point students, educators and parents to this valuable resource." Wendy Hawkins, Executive Director of the Intel Foundation"The Winners' Guide offers terrific insight and information to encourage increased numbers of students and teachers to seek out lab-based experiences to enrich and strengthen their scientific acumen."

Book Description
Provides a complete understanding of how our bodies respond to toxicants, and the principles used to assess the health risks of specific exposure scenarios Toxicology and Risk Assessment: A Comprehensive Introduction, Second Edition reflects recent advances in science and technology, and provides the scientific background and methodological issues to enable the reader to understand the basic principles in toxicology and to evaluate the health risks of specific exposure scenarios. Completely updated with the latest information, this book offers a concise introduction to the subject. It is divided into five sections: Principles in Toxicology, Organ Toxicology, Methods in Toxicology, Regulatory Toxicology, and Specific Toxicity. The 2nd Edition adds new chapters that cover recent scientific and technological advances and current topics including the endocrine system, alternatives to animal testing, risk assessment and thresholds for carcinogens, European and international regulation, nanomaterials, fuels, fragrances, and agrochemicals. Concentrates on the basic concepts of toxicology and provides sufficient information for the reader to become familiar with them in order to understand the principles and to evaluate the risks at given exposures 30% new chapters cover recent scientific and technological advances including alternatives to animal testing; genotoxic carcinogens; REACH regulations; nanomaterials; fuels; fragrances; PAHs; and agrochemicals Written by a team of international specialists, and edited by two outstanding scientists in the field Fully updated and expanded, Toxicology and Risk Assessment: A Comprehensive Introduction, Second Edition is an essential text for any student or researcher with an interest in toxicology and related risk assessments.
