It focuses particularly on the chemistry, pharmacology, and biological activities of essential oils, with contributions from a worldwide group of




Essential Oils


Book Description

Essential Oils: Contact Allergy and Chemical Composition provides a full review of contact allergy to essential oils along with detailed analyses of the chemical composition of essential oils known to cause contact allergy. In addition to literature data, this book presents the results of nearly 6,400 previously unpublished sample analyses, by far the largest set of essential oils analyses ever reported in a single source of scientific literature. Covering 91 essential oils and two absolutes, the book presents an alphabetical list of all 4,350 ingredients that have been identified in them, a list of chemicals known to cause contact allergy and allergic contact dermatitis, and tabular indications of the ingredients that can be found in each essential oil. The book discusses contact allergy and allergic contact dermatitis for each of the oils and absolutes, sometimes able to provide only one or two reports but drawing upon considerable amounts of literature in other cases, such as with tea tree oil, ylang-ylang oil, lavender oil, rose oil, turpentine oil, jasmine absolute, and sandalwood oil. While limited information on the main components and their concentrations would be enough for most dermatologists, this book gives extensive coverage not only to improve levels of medical knowledge and quality of patient care, but also for the benefit of professionals beyond clinical study and practice, such as chemists in the perfume and cosmetics industries, perfumers, academic scientists working with essential oils and fragrances, aromatherapists, legislators, and those involved in the production, sale, and acquisition of essential oils.

Essential Mathematics for Engineers and Scientists


Book Description

This text is geared toward students who have an undergraduate degree or extensive coursework in engineering or the physical sciences and who wish to develop their understanding of the essential topics of applied mathematics. The methods covered in the chapters form the core of analysis in engineering and the physical sciences. Readers will learn the solutions, techniques, and approaches that they will use as academic researchers or industrial R&D specialists. For example, they will be able to understand the fundamentals behind the various scientific software packages that are used to solve technical problems (such as the equations describing the solid mechanics of complex structures or the fluid mechanics of short-term weather prediction and long-term climate change), which is crucial to working with such codes successfully. Detailed and numerous worked problems help to ensure a clear and well-paced introduction to applied mathematics. Computational challenge problems at the end of each chapter provide students with the opportunity for hands-on learning and help to ensure mastery of the concepts. Adaptable to one- and two-semester courses.

Essential Precalculus


Book Description

This no-nonsense guide provides students and self-learners with a clear and readable study of the most important ideas of precalculus mathematics. Tim Hill's distraction-free approach combines decades of tutoring experience with the proven methods of his Russian math teachers. The result: learn in a few weeks what conventional schools stretch into months. - Teaches general principles that can be applied to a wide variety of problems. - Avoids the mindless and excessive routine computations that characterize conventional textbooks. - Treats the subject as a logically coherent discipline, not as a disjointed collection of techniques. - Restores proofs to their proper place to remove doubt, convey insight, and encourage precise logical thinking. - Omits digressions, excessive formalities, and repetitive exercises. - Provides exceptional preparation for a calculus course. - Includes problems (with all solutions) that extend your knowledge rather than merely reinforce it. Contents 1. The Real Line and Coordinate Plane 2. Straight Lines 3. Circles and Parabolas 4. Functions 5. Graphs 6. Trigonometry 7. Solutions
