Lipids have a variety of functions in the human body which have increasingly been under the spotlight in recent years. A multidisciplinary book, Lipids in health and nutrition addresses the chemical, biochemical and physiological aspects of these widely occurring compounds. International experts combine to present research on a variety of topics, including advanced analytical techniques; the role of flavonoids in diet: possible links between dyslexia, dyspraxia and attention deficit disorder and the metabolism of fatty acids; the influence of dietary fatty acids in coronary heart disease; and lipids and obesity.

Since 80% of the global production of oils and fats is consumed as food and a further 6% is eaten by animals to produce more human food, it is not surprising that nutrition is one of the active areas in lipid science. For 10 years, Mike Gurr has written nutrition articles in lipid technology amounting to nearly 60 reviews. The result is a powerful and critical survey of important aspects of lipid nutrition which will be appreciated by lipid technology readers and should be compulsory reading for those not familiar with the original articles.

Areas covered include: influence of dietary fats on the concentrations of lipids carried in the blood and the significance for health, the nutritional and biological properties of the polyunsaturated fatty acids, and lipids in foods and raw materials, among other topics.

Liquid Acquisition Devices for Advanced In-Space Cryogenic Propulsion Systems discusses the importance of reliable cryogenic systems, a pivotal part of everything from engine propulsion to fuel deposits. As some of the most efficient systems involve advanced cryogenic fluid management systems that present challenging issues, the book tackles issues such as the difficulty in obtaining data, the lack of quality data and models, and the complexity in trying to model these systems.

The book presents models and experimental data based on rare and hard-to-obtain cryogenic data. Through clear descriptions of practical data and models, readers will explore the development of robust and flexible liquid acquisition devices (LAD) through component-level and full-scale ground experiments, as well as analytical tools.

This book presents new and rare experimental data, as well as analytical models, in a fundamental area to the aerospace and space-flight communities. With this data, the reader can consider new and improved ways to design, analyze, and build expensive flight systems.

Liquid Crystals provides information pertinent to the characterization and understanding of the liquid crystalline or ordered fluid. This book presents the important developments in the understanding of liquid crystals.

Organized into seven chapters, this book begins with an overview of the various relations between liquid crystals and polymers. This text then examines the synthesis of very simple families of liquid crystals of the types required by the laboratory physicists. Other chapters consider the process of reorientation of the permanent dipole moments connected with changes in the field, which requires a definite time interval. This book discusses as well the lyotropic liquid crystals that can be formed by amphiphilic molecules as different as lipids and copolymers. The final chapter deals with the aspect of molecular pattern, which seems to be the most underestimated in the consideration of biological phenomena found in liquid crystal.

This book is a valuable resource for scientists, physicists, and chemists.

Inductively coupled plasma atomic or mass spectrometry is one of the most common techniques for elemental analysis. Samples to be analyzed are usually in the form of solutions and need to be introduced into the plasma by means of a sample introduction system, so as to obtain a mist of very fine droplets. Because the sample introduction system can be a limiting factor in the analytical performance, it is crucial to optimize its design and its use. It is the purpose of this book to provide fundamental knowledge along with practical instructions to obtain the best out of the technique.

- Fundamental as well as practical character
- Troubleshooting section
- Flow charts with optimum systems to be used for a given application
