Textbook of Biological Psychiatry
Wiley-Liss; 1 edition | November 10, 2003 | ISBN: 0471434787 | 736 pages | PDF | 100 MB

A Textbook of Biological Psychiatry integrates the basic science concerning brain mechanisms of psychiatric disorders alongside surveys of present standard clinical treatment. Organized in a coherent and easy to follow structure, chapters expand across different levels of analysis, from basic mechanisms to clinical practice. This comprehensive reference provides an integrative treatment of the biochemistry of neurotransmission, behavioral pharmacology, and clinical aspects of psychiatric problems including depression, manic-depression, and mood disorders. Other chapters address the biological mechanisms and treatment of depression, anxiety, panic, obsessive-compulsive disorder and addictions. The editor concludes with a perspective on the future of the field and prospects for understanding and effectively treating mood and anxiety disorders.

Towards a Thermodynamic Theory for Ecological Systems by: S.E. Jorgensen, Y.M. Svirezhev
Publisher: Pergamon | July 20, 2004 | ISBN: 008044167X | Pages: 380 | PDF | 3.25 MB

The book presents a consistent and complete ecosystem theory based on thermodynamic concepts. The first chapters are devoted to an interpretation of the first and second law of thermodynamics in ecosystem context. Then Prigogine's use of far from equilibrium thermodynamic is used on ecosystems to explain their reactions to perturbations. The introduction of the concept exergy makes it possible to give a more profound and comprehensive explanation of the ecosystem's reactions and growth-patterns. A tentative fourth law of thermodynamic is formulated and applied to facilitate these explanations. The trophic chain, the global energy and radiation balance and pattern and the reactions of ecological networks are all explained by the use of exergy. Finally, it is discussed how the presented theory can be applied more widely to explain ecological observations and rules, to assess ecosystem health and to develop ecological models.

Illicium, Pimpinella and Foeniculum (Medicinal and Aromatic Plants--Industrial Profiles) by Manuel Miro Jodral
Publisher: CRC Press | May 27, 2004 | ISBN: 0415322464 | Pages: 176 | PDF | 6.31 MB

Known usually by their commercial names-star anise, aniseed and fennel, respectively-illicium, pimpinella and foeniculum are spices with a rich history. In addition to their traditional uses, each has multiple applications in botany, chemistry, pharmacology and therapy. The author, along with expert contributors, discusses this range of applications and presents data on the ecological and biological characteristics of these genera. The text gives a full profile for each species, including practices for cultivating, drying and storing the plants. Their performance in the marketplace is also reviewed, with a look at their economic importance and future trends. University professors and students in botany, pharmacology, phytochemistry and medicine will benefit from this volume.

Bivalve Molluscs: Biology, Ecology and Culture by: Elizabeth Gosling
Publisher: Blackwell Publishing Limited | 01-02-2003 | ISBN: 0852382340 | 456 pages | 3.28 Mb

Comprehensive text covers all major aspects of the invertebrate class bivalve molluscs. Chapters cover morphology, ecology, feeding, reproduction, settlement and recruitment, growth, physiology, fisheries, aquaculture, genetics, diseases and parasites, and public health issues. Primarily for undergraduate students, but useful as a reference for postgraduate students and professionals.

Chemical Pesticide Markets, Health Risks and Residues By Jeremy Harris
Publisher: CABI | 12-10-2000 | ISBN: 0851994768 | 64 pages | 18.4 Mb

During recent decades, there has been a steady increase in the use of chemical pesticides in both developed and developing countries. This has caused widespread concern about their impact on human health and on the environment. This is particularly the case in less developed countries which may lack appropriate resources to minimize the risks and rectify problems. The purpose of this book is to provide a review of:information on the scale of manufacture, import, export and use of chemical pesticides; examples of direct risks to human welfare in terms of acute poisonings caused by occupational exposure and pesticide residues in food; examples of problems with the storage of obsolete stocks of pesticides in developing countries. The focus is on acute problems in developing countries, particularly in Latin America, Asia and Africa, but some information is also provided about developed countries.

WE ARE DIGGING OUR ECOLOGICAL CRYPT?
Publisher: Irish Publishing | ISBN: 9780982307602 | edition 2008 | PDF | 39 pages | 1,67 mb

Commander Gulliver and his friends discuss some ecological problems, particularly those related to the causes of global warming and it eventual effects. They also list some solutions for the problem. Understanding the global problems will help them to understand solutions being attempted in some of the countries they will soon visit.

Stevia: The Genus Stevia (Medicinal and Aromatic Plants - Industrial Profiles) by A. Douglas Kinghorn
Publisher: CRC Press | November 29, 2001 | ISBN: 0415268303 | Pages: 224 | PDF | 4.69 MB

This comprehensive volume provides reviews on the botany, ethnobotany, and chemical constituents of the genus Stevia and examines the chemical synthesis of such compounds as steviol and stevioside.

On the whole, this book is an excellent source of information and should be an important acquisition for any professional interested in natural products, medicinal plants and research. - Ricardo O.Guerro
