Limnological analyses

[by] J. B. Harborne

Phytochemistry is a rapidly expanding area with new techniques being developed and existing ones perfected and made easier to incorporate as standard methods in the laboratory. This edition includes descriptions of methods such as HPLC and the increasingly sophisticated NMR and related spectral techniques. Other methods described are the use of NMR to locate substances within the plant cell and the chiral separation of essential oils. After an introductory chapter on methods of plant analysis, individual chapters describe methods of identifying the different type of plant molecules: phenolic compounds, terpenoids, organic acids, lipids and related compounds, nitrogen compounds, sugar and derivatives and macromolecules. Different methods are discussed and recommended, and guidance provided for the analysis of compounds of special physiological relevance such as endogenous growth regulators, substances of pharmacological interest and screening methods for the detection of substances for taxonomic purposes.

Gale Lawrence

"This field guide invites all aspiring naturalists to focus on one familiar plant, animal, or natural phenomenon at a time, and observe it in detail. It offers descriptive information on dozens of common subjects - from frost and fruit flies to blue jays and beech trees - and includes a drawing of each. Organized by seasons, it encourages readers to look more closely at the natural cycles of life in our world, and discover how much there is to learn. Whether read sequentially or used as a field companion or handy desk reference, A Field Guide to the Familiar (first published in 1984, and reprinted here with new reading suggestions) gives everyone a sense of the natural world as an accessible - and endlessly fascinating - place."--Jacket.

Rein Taagepera

"In his challenging new book Rein Taagepera argues that society needs more from social sciences than they have delivered. One reason for falling short is that social sciences have depended excessively on regression and other statistical approaches, neglecting logical model building. Science is not only about the empirical 'What is?' but also very much about the conceptual 'How should it be on logical grounds?' Statistical approaches are essentially descriptive, while quantitatively formulated logical models are predictive in an explanatory way. Making Social Sciences More Scientific contrasts the predominance of statistics in today's social sciences and predominance of quantitatively predictive logical models in physics. It shows how to construct predictive models and gives social science examples. Making Social Sciences More Scientific is useful to students who wish to learn the basics of the scientific method and to all those researchers who look for ways to do better social science."--Jacket.

Essential in biological functions like cell signaling and, when disturbed, a likely cause of disease, lipids have proven to be a vital force in cell biology. In Lipidomics: Methods and Protocols, an international panel of experts present a wide variety of reviewed as well as unpublished data on isolation techniques, structural analysis, lipid rafts, lipid trafficking and profiling, biomarkers, lipid peroxidation, biostatistics applied to lipids, software tools, and bioinformatics. These studies range from simple systems, such as in yeast, to complex biological models. Samples used in these studies include: mitochondria, microsomes, endosomal membranes, RBS and plasma membranes, vesicles, caveolae, liposomes, macrophages, meibum, brain, microglia, retina, adipose tissue, keratinocytes, pulmonary surfactant, and hepatic cultures. Volume 2 focuses on oxidized lipids, trafficking and profiling, software, bioinformatics, and biostatistics. Written in the highly successful Methods in Molecular Biology"!series format, the chapters include useful introductions to their respective topics, lists of the necessary equipment and materials, step-by-step, readily reproducible laboratory protocols, and authoritative notes on troubleshooting and avoiding common pitfalls. Comprehensive and cutting-edge, Lipidomics: Methods and Protocols will support researchers who wish to increase their utilization of lipidomics, which will certainly lead to more powerful technology, improved diagnostic-prognostic capabilities, and the identification of new valuable products
