Rhodiola rosea (Traditional Herbal Medicines for Modern Times) by Alain Cuerrier, Kwesi Ampong-Nyarko
2014 | ISBN: 143988840X | English | 304 pages | PDF | 33 MB

Rhodiola rosea
The genus Rhodiola (Family Crassulaceae) is indigenous to Northern Canada, Europe and Asia where its rhizomes and roots have been used for centuries for medicinal purposes. Recent interest in the species (roseroot) in the West arose from the use of the rhizome as an adaptogen for the treatment of stress, but in the last few years, chemical and pharmacological studies have confirmed other valuable medicinal properties.

Written by well-known researchers in this field of study, examines important aspects of this increasingly important medicinal plant, including:

Cultivation
Taxonomy
Ethnobotany
Conservation
Phytopathology
Phytochemistry
Pharmacology
Biotechnology

The book discusses in vitro culture of R. rosea and examines pests and diseases affecting the plant in Europe, Canada, and Alaska. It also examines pharmacological bioassays and toxicology. The contributors provide a meta-analysis of clinical trials and describe experimentation with R. rosea in clinical practice. They explore its use in a range of areas, including for depression and anxiety disorders, to improve sexual and immune functions, to augment cancer treatment, and in aerospace medicine for afflictions such as mountain sickness and jet lag. The final chapter uses a model to illustrate the cultivation of R. rosea as an industrial crop from field to medicine to cabinet. Synthesizing the most important literature in recent years, the book supplies a comprehensive peer-reviewed survey of the wide spectrum of possibilities for its use as a modern phytomedicinal agent.

Understanding Immunology, 3rd Edition (Cell and Molecular Biology in Action) by Peter Wood
English | 2011 | ISBN: 0273730681 | 392 pages | PDF | 21,4 MB

Understanding Immunology, 3rd Edition
Understanding Immunology is a well-established introduction to this complex subject for readers with no previous exposure. It is aimed primarily at undergraduates in biological sciences, biomedical sciences and medicine. The selection and order of topic coverage is designed to instruct effectively, and a variety of boxed examples add depth and historical context for those readers wanting to go beyond the essentials. The first part of the book (Chapters 1 to 11) takes students through the pathogenesis of infectious diseases and describes the molecules, cells and tissues of the immune system that provide protection against a wide variety of pathogens. It also describes how mankind has utilised the immune system, from the development of vaccines to the production of reagents for use in the clinic and laboratory. The final four chapters describe how the immune system operates in disease situations such as allergy, autoimmunity and transplantation. This third edition is revised to cover the latest experimental and clinical changes in the subject, particularly those in the development of lymphocytes; the different types of CD4 helper T cells; the use of antibodies, including monoclonal antibodies, as experimental and clinical tools; and immunological tolerance. Dr. Peter Wood is a Lecturer in the Faculty of Life Sciences at the University of Manchester. He has over 20 years of teaching experience, both in the UK and in the USA, and is widely published in the literature. His current research interest is the role of cytokines in the development of diabetes.

Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials

FREEDownload : Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials

Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials by G. V. Kozlov, Yu G. Yanovskii
2014 | ISBN: 1771880414 | English | 384 pages | PDF | 11 MB

Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials
This new book explores the consideration of relationships that connect the structural and basic mechanical properties of polymeric mediums within the frameworks of fractal analysis with cluster model representations attraction. Incidentally, the choice of any structural model of medium or their combinations is defined by expediency and further usage convenience only. This book presents leading-edge research in this rapidly changing and evolving field.

The book presents descriptions of the main reactions of high-molecular substances within the frameworks of fractal analysis and irreversible aggregation models. Synergetics and percolation theory were also used. In spite of the enormous number of papers dealing with the influence of the medium on the rate of chemical reactions (including synthesis of polymers), no strict quantitative theory capable of "universal" application has been put forward up until now. It is now possible to describe the relationship between the reaction rate constants and the equilibrium constants with the nature of the medium in which the reactions take place by means of a single equation. This important book for the first time gives structural and physical grounds of polymers synthesis and curing, and the fractal analysis is used for this purpose.

This new book:

* Highlights some important areas of current interest in polymer products and chemical processes

* Focuses on topics with more advanced methods

* Emphasizes precise mathematical development and actual experimental details

* Analyzes theories to formulate and prove the physicochemical principles

* Provides an up-to-date and thorough exposition of the present state of the art of complex polymeric materials

Nonlocal Continuum Field Theories

Nonlocal Continuum Field Theories
English | Physics, Mechanics | 1. Jule 2002 | ISBN-10: 0387952756 | 376 pages | pdf | 2 mb
Nonlocal continuum field theories are concerned with material bodies whose behavior at any interior point depends on the state of all other points in the body — rather than only on an effective field resulting from these points — in addition to its own state and the state of some calculable external field.

Nonlocal Continuum Field Theories
nonlocal continuum field theories are concerned with material bodies whose behavior at any interior point depends on the state of all other points in the body — rather than only on an effective field resulting from these points — in addition to its own state and the state of some calculable external field. Nonlocal field theory extends classical field theory by describing the responses of points within the medium by functionals rather than functions (the "constitutive relations" of classical field theory). Such considerations are already well known in solid-state physics, where the nonlocal interactions between the atoms are prevalent in determining the properties of the material. The tools developed for crystalline materials, however, do not lend themselves to analyzing amorphous materials, or materials in which imperfections are a major part of the structure. Nonlocal continuum theories, by contrast, can describe these materials faithfully at scales down to the lattice parameter. This book presents a unified approach to field theories for elastic solids, viscous fluids, and heat-conducting electromagnetic solids and fluids that include nonlocal effects in both space and time (memory effects). The solutions to the field equations agree remarkably well with atomic theories and experimental observations.

Nonlinear Waves in Elastic Crystals
English | Physics, Mathematics | January 2000 | ISBN-10: 0198534841 | 320 pages | Djvu | 3.2 mb
The mathematical modelling of changing structures in materials is of increasing importance to industry where applications of the theory are found in subjects as diverse as aerospace and medicine.

Nonlinear Waves in Elastic Crystals
This book deals with aspects of the nonlinear dynamics of deformable ordered solids (known as elastic crystals) where the nonlinear effects combine or compete with each other. Physical and mathematical models are discused and computational aspects are also included. Different models are considered – on discrete as well as continuum scales – applying heat, electricity, or magnetism to the crystal structure and these are analysed using the equations of rational mechanics. In this way the student is introduced to the important equations of nonlinear science that describe shock waves, solitons and chaos and also the non-exactly integrable systems or partial differential equations. A large number of problems and examples are included, many taken from recent research and involving both one-dimensional and two-dimensional problems as well as some coupled degress of freedom.
