Abstract The year 2008 marked the one hundredth anniversary of the observational discovery
by George Ellery Hale of magnetic field in sunspots (Hale in Astrophys. J. 28:315–343,
1908). This observation, the first to suggest a direct link between the best-known variable
features on the Sun and magnetism, started a line of research that has widened considerably
over the last 100 years and is continuing today. Knowledge about all aspects of the Sun
has increased in a remarkable way over the past few decades....
Govender et al. present an important overview of criteria employed to predict
recurrence and progression to MS, with particular attention given to radiological
findings. Guevara Campos and González Guevara focus specifically on Landau
Kleffner syndrome (LKS; sometimes called infantile acquired aphasia), in which
language comprehension and expression impairments emerge after an initial period of
An integrated approach among the local, State, and Federal Government provides for a
logical clearinghouse for intelligence on the movement and activities of terrorist groups and
the collection, interpretation, and dissemination of that information to the proper
enforcement agencies. Effective planning and intelligence gathering can lessen the
likelihood of a surprise emergency incident, which, improperly handled, can make or break a
department and its administrators at all levels of government.
A suite of emerging techniques, known collectively as “molecular imaging,” now
offer scientists an unprecedented opportunity to identify, follow, and quantify
biologic processes at the cellular level with molecular specificity in intact organisms.
For instance, it is now possible to evaluate, with imaging, the distribution,
magnitude, and timing of gene expression in genetically altered animals (1–3).
This cross-disciplinary book documents the key research challenges in the mathematical sciences and physics that could enable the economical development of novel biomedical imaging devices. It is hoped that the infusion of new insights from mathematical scientists and physicists will accelerate progress in imaging.
The last quarter of the last century has witnessed major advancements that have brought
imaging and radioanalytical techniques to a paramount status in life sciences and industry.
Generally speaking, the scope of radiation imaging and radioanalytics covers data acquisi‐
tion, data processing, and data analysis, involving theories, methods, systems and applica‐
tions. While detection and post-processing techniques become increasingly sophisticated,
traditional and emerging modalities play more and more critical roles in medical and indus‐
Noninvasive Imaging of Myocardial Ischemia provides a comprehensive discussion and
review of the noninvasive myocardial imaging techniques that are currently available to
detect myocardial ischemia and infarction. Topics covered include echocardiography,
cardiac magnetic resonance imaging, myocardial perfusion scintigraphy, positron
emission tomography, and computed tomography.

The FR-D700 series is compliant to the EU Machinery Directive without the addition of previously required external devices. Operation of an external Emergency Stop device results in a highly reliable immediate shutoff of the D700's output to the motor. This safety stop function conforms to the following standards.
The permanent-magnet synchronous machine (PMSM) drive has emerged as a top competitor for a full range of motion control applications [1–3]. For example, the PMSM is widely used in machine tools, robotics, actuators, and is being considered in high-power applications such as vehicular propulsion and industrial drives. It is also becoming viable for commercial/residential applications. The PMSM is known for having high efﬁciency, low torque ripple, superior dynamic performance, and high power density.
Offering step-by-step, in-depth coverage, the new Third Edition of Power Electronics: Converters, Applications, and Design provides a cohesive presentation of power electronics fundamentals for applications and design in the power range of 500 kW or less. The text describes a variety of practical and emerging power electronic converters made feasible by the new generation of power semiconductor devices. The new edition is now enhanced with a new CD-ROM, complete with PSpice-based examples, a new magnetics design program, and PowerPoint slides.
Summary. In this introductory chapter, the definition and history of tribology and their industrial
significance and origins and significance of an emerging field of micro/nanotribology
are described. Next, various measurement techniques used in micro/nanotribological and
micro/nanomechanical studies are described. The interest in micro/nanotribology field grew
from magnetic storage devices and latter the applicability to emerging field micro/nanoelectromechanical
systems (MEMS/NEMS) became clear.
The first edition of the
Handbook of Micro/Nanotribology
was published in the Spring of 1995. Soon after
its publication, the first-of-a-kind monograph became a reference book for the novice, as well as experts,
in the emerging field of micro/nanotribology. Since the field is evolving very rapidly, we felt that the
monograph needed a second edition.
The second edition is totally revised. The scope of the first edition has been expanded. In the first
part, Basic Studies, two new chapters on AFM Instrumentation and Tips and Surface Forces and Adhesion
have been added.
Cd1-xMnxS nanoparticles (NPs) with size quantum confinement belong to the diluted
magnetic semiconductor (DMS) quantum dot (QD) class of materials that has been widely
studied in the last few years. The study of quasi-zero-dimensional Diluted Magnetic
Semiconductors (DMS), such as Cd1-xMnxS Quantum Dots (QDs), is strongly motivated due
to the localization of magnetic ions in the same places as the free-like electron and hole
carriers occurring in these nanomaterials [1,2].
Metabolomics (or metabonomics) is metabolite profil-
ing, measuring the real outcome of the potential changes
suggested by genomics and proteomics. Metabolomics
investigates regulation and metabolic fluxes in individual
cells or cell types. Metabonomics combines the power of
high-resolution nuclear magnetic resonance with statistical
data analysis of in vivo metabolite patterns. This technique
enables rapid screening for xenobiotic toxicity, disease state,
drug efficiency, nutritional status and even gene function
in the “whole” organism. (Nicholson et al., 2002).
