Nuclear magnetic resonance (NMR) is an analytical tool used by
chemists and physicists to study the structure and dynamics of
molecules. In recent years, no other technique has gained such
significance as NMR spectroscopy. It is used in all branches of
science in which precise structural determination is required and
in which the nature of interactions and reactions in solution is
being studied. "Annual Reports on NMR Spectroscopy" has established
itself as a premier means for the specialist and non-specialist
alike to become familiar with new techniques and applications of
NMR spectroscopy. * Provides updates on the latest developments in NMR spectroscopy * Includes comprehensive review articles * Highlights the increasing importance of NMR spectroscopy as a technique for structural determination
Volume 4 of Biomembranes covers endocytosis, exocytosis and related processes. A major role of the plasma membrane is as a permeability barrier, keeping the inside of the cell inside and the outside, outside. Mechanisms must then exist to allow movement of material between the cell and its environment. One mechanism for export from the cell is by exocytosis, a process in which the membranes of secretory vesicles fuse with the plasma membrane releasing the contents of the vesicle into the extracellular medium. The process has been studied in particular depth for the release of neurotransmitters at the synapse. Import into the cell is possible by the process of receptor-mediated endocytosis in which selected plasma membrane proteins are internalizes; when these proteins are receptors for macromolecules, the result is uptake of the macromolecule. Transferring, the low-density lipoprotein, and asialoglycoproteins are all taken up into cells in this way. Phagocytosis, the ingestion of cells and cell fragments by neutrophils and macrophages, also involves receptors - on the phagocytic membrane - of which the best studied are those for the Fc domain of IgG, for the third component of complement, and for the mannose/fructose carbohydrates. Protection of a host against infection can also be achieved by damaging the integrity of the plasma membrane of the invading organism. This is the strategy evolved by the cytotoxic T lymphocytes, which produce a pore-forming toxin, perforin. Volume 4 of Biomembranes explores the structures and mechanisms involved in these biologically and medically important processes.
Advances in agriculture offer many countries the best and only chance of reducing poverty. Yet economic growth and population increases are driving higher demand for food and rising real prices. What solutions have successfully promoted agriculture? This volume examines national and international food agriculture policies and how they enhance agricultural productivity growth. It provides unique historical reviews on policies and their effects, and it clearly articulates both positive and negative lessons for promoting agriculture lead growth. With chapters written by international authorities, this book recognizes that agriculture is not just about providing food for today, but about growing it in an environmentally sustainable way that can help people work their ways out of poverty.Chapters cover international macro-economic policies and trade, farm structure in developing countries, regional experiences in agriculture, and regional studies on agricultural productivity policies.
This work is an interdisciplinary, cross-cultural, widely-calibrated checklist for EU sustainable landscape management, which is intended to serve both as an analytical tool of reference as well as a design tool for local, regional and European policy making on sustainable developments. The tool has been developed out of a multidisciplinary study in EU countries which was designed to find out what would be the overall requirements for a sustainable management of the landscape of rural areas. Could these stipulations be brought together in a comprehensive system with sufficient consistency to comply with the notion that the landscape is an entity, which should be managed accordingly? Cooperation of the scientific experts with those involved in the practical side, and alternating plenary reporting with subgroup visits to farms in the rural landscapes of the participants' countries, allowed for the development of some truly interdisciplinary teamwork. Organic agriculture has been included to find out how organic agriculture contributes to the rural landscape.

Hyaluronan biology is being recognized as an important regulator of
cancer progression. Paradoxically, both hyaluronan (HA) and
hyaluronidases, the enzymes that eliminate HA, have also been
correlated with cancer progression. Hyaluronan, a long-chain
polymer of the extracellular matrix, opens up tissue spaces through
which cancer cells move and metastasize. It also confers motility
upon cells through interactions of cell-surface HA with the
cytoskeleton. Embryonic cells in the process of movement and
proliferation use the same strategy. It is an example of how cancer
cells have commandeered normal cellular processes for their own
survival and spread. There are also parallels between cancer and
wound healing, cancer occasionally being defined as a wound that
does not heal.
Electronics are used in a wide range of applications including
computing, communication, biomedical, automotive, military and
aerospace. They must operate in varying temperature and humidity
environments including indoor controlled conditions and outdoor
climate changes. Moisture, ionic contamination, heat, radiation and
mechanical stresses are all highly detrimental to electronic
devices and can lead to device failures. Therefore, it is essential
that the electronic devices be packaged for protection from their
intended environments, as well as to provide handling, assembly,
electrical and thermal considerations.
Stress is a universal phenomenon that impacts adversely on most
people. This volume provides a readily accessible compendium that
focuses on the physical and psychological consequences of stress
for individuals and society. Clinical attention focuses on
disorders of the stress control system (e.g. Cushing s Syndrome:
Addison s Disease) and the adverse impact of stress on human
physical and mental health. Detailed reviews address disorders such
as PTSD, anxiety, major depression, psychoses and related disorders
such as combat fatigue and burnout. The work covers interactions
between stress and neurodegenerative disorders, such as Alzheimer s
disease and Parkinson s disease, as well as
stress-immune-inflammatory interactions in relation to cancer and
autoimmune and viral diseases. Emphasis is also placed on the role
of stress in obesity, hypertension, diabetes type II and other
features of the metabolic syndrome which has now reached epidemic
proportions in the USA and other countries.
The addictions treatment field is currently undergoing a period of
increased scrutiny, upheaval and change. The growing emphasis on
treatment accountability and cost effectiveness is leading to major
changes in standards of care. Inconsistent practices based solely
on clinical intuition rather than hard scientific evidence of
treatment efficacy are rapidly becoming unacceptable.
Modern embedded systems require high performance, low cost and low power consumption. Such systems typically consist of a heterogeneous collection of processors, specialized memory subsystems, and partially programmable or fixed-function components. This heterogeneity, coupled with issues such as hardware/software partitioning, mapping, scheduling, etc., leads to a large number of design possibilities, making performance debugging and validation of such systems a difficult problem. Embedded systems are used to control safety critical
applications such as flight control, automotive electronics and
healthcare monitoring. Clearly, developing reliable
software/systems for such applications is of utmost importance.
This book describes a host of debugging and verification methods
which can help to achieve this goal.

The Bayesian network is one of the most important architectures for representing and reasoning with multivariate probability distributions. When used in conjunction with specialized informatics, possibilities of real-world applications are achieved. Probabilistic Methods for BioInformatics explains the application of probability and statistics, in particular Bayesian networks, to genetics. This book provides background material on probability, statistics, and genetics, and then moves on to discuss Bayesian networks and applications to bioinformatics. Rather than getting bogged down in proofs and algorithms,
probabilistic methods used for biological information and Bayesian
networks are explained in an accessible way using applications and
case studies. The many useful applications of Bayesian networks
that have been developed in the past 10 years are discussed.

Treatise on Geophysics: Mantle Dynamics, Volume 7 aims to provide both a classical and state-of-the-art introduction to the methods and science of mantle dynamics, as well as survey leading order problems (both solved and unsolved) and current understanding of how the mantle works. It is organized around two themes: (1) how is mantle convection studied; and (2) what do we understand about mantle dynamics to date. The first four chapters are thus concerned with pedagogical reviews of the physics of mantle convection; laboratory studies of the fluid dynamics of convection relevant to the mantle; theoretical analysis of mantle dynamics; and numerical analysis and methods of mantle convection. The subsequent chapters concentrate on leading issues of mantle convection itself, which include the energy budget of the mantle; the upper mantle and lithosphere in and near the spreading center (mid-ocean ridge) environment; the dynamics of subducting slabs; hot spots, melting anomalies, and mantle plumes; and finally, geochemical mantle dynamics and mixing.
Treaties on Geophysics: Core Dynamics, Volume 8, provides a comprehensive review of the current state of understanding of core dynamics. The book begins by analyzing a subject of long-standing and on-going controversy: the gross energetics of the core. It then explains the important elements of dynamo theory; actual fluid motions in the core; the basic physical principles involved in thermochemical convection in the core and the basic equations governing the convection; and turbulence and the small-scale dynamics of the core. This is followed by discussions of the state of knowledge on rotation-induced core flows; the use of first-principles numerical models of self-sustaining fluid dynamos; and the behavior of polarity reversals in numerical dynamo models. The remaining chapters cover the various roles the inner core plays in core dynamics and the geodynamo; experiments that have shaped knowledge about the flows in the core that produce the geodynamo and govern its evolution; and ways the mantle can affect core dynamics, and corresponding ways the core can affect the mantle.
Geodesy, which is the science of measuring the size and shape of the Earth, explores the theory, instrumentation and results from modern geodetic systems. The beginning sections of the volume cover the theory of the Earth's gravity field, the instrumentation for measuring the field, and its temporal variations. The measurements and results obtained from variations in the rotation of the Earth are covered in the sections on short and long period rotation hanges. Space based geodetic methods, including the global positioning system (GPS) and Interferometric synthetic aperture radar (SAR), are also examined in detail. Self-contained volume starts with an overview of the subject
then explores each topic with in depth detail
Treatise on Geophysics: Geomagnetism, Volume 5, provides an overview of the most important aspects of geomagnetism. The book begins by tracing the history of the study of geomagnetism. It then reviews global models of the Earth's magnetic field; the main sources of external magnetic field contributions; and the instruments and practices used to observe and measure the full range of features of the geomagnetic field. It discusses the origins of current knowledge of the secular variation of the Earth's magnetic field; crustal magnetism; geomagnetic excursions; the study of geophysical electromagnetic induction; the magnetization process; and the status of recent magnetic field data and their applications. The remaining chapters cover the geometry of the geomagnetic field and its temporal variability as recorded in volcanic and sedimentary rocks over the past few million years; the ocean crust as a recorder of geomagnetic field variations; and the theoretical basis for paleointensity experiments in igneous and sedimentary environments. The final chapter explains the concept of true polar wander (TPW), defined as shifts in the geographic location of Earth's daily rotation axis and/or by fluctuations in the spin rate (length of day anomalies).
Evolution of the Earth focuses on the formation of Earth. Topics
include the differention of the core, mantle and crust; the
formation of the ocean basins and continents; outgassing and
volcanism; the initiation of plate tectonics, the origin and
persistence of Earth's magnetic field; the growth of the inner
core; changes in mantle convection through time; and the impact of
life on the planet. The volume takes an interdisciplinary viewpoint
that emphasizes the interplay of geophysics, other aspects of earth
science and biological evolution. Some outstanding questions are
identified and debated. |
