Vortices and Turbulence at Very Low Temperatures
Recent investigations have highlighted the similarities between turbulence in cryogenic fluids at temperatures close to absolute zero, in particular superfluid helium, and turbulence in ordinary fluids. This book contains lectures on various theoretical and experimental aspects of the problem given by experts at the advanced school “Vortices and Turbulence at Low Temperatures” held at CISM, Udine, in the summer of 2007. The lectures provide an introduction into this rapidly expanding area of research.
Vortex Dominated Flows : Analysis and Computation for Multiple Scale Phenomena
Addressed to both graduate students and researchers this monograph provides in-depth analyses of vortex dominated flows via matched and multiscale asymptotics, and it demonstrates how insight gained through these analyses can be exploited in the construction of robust, efficient, and accurate numerical techniques.
Volunteering and Social Inclusion : Interrelations between Unemployment and Civic Engagement in Germany and Great Britain
Conceptualising employment and volunteering as two distinct forms of social inclusion, Susanne Strauß analyses their interrelations in Germany and Great Britain. On the basis of household panel data, she answers questions such as: Does job loss lead people to give up their volunteer work? Or do people who have lost their job keep up their volunteering activities to use them as an alternative source of social recognition? Does volunteering help with finding a new job? By comparing the situation in two different countries, the author stresses that differences in labour market institutions lead to distinct answers. Moreover, the study points to variations with respect to gender, education and the type of volunteering organisations.
Voltage-Sensitive Ion Channels : Biophysics of Molecular Excitability
Explores the complexity of a microscopic bit of matter that exists in a myriad of copies within our bodies, the voltage-sensitive ion channel. We seek to investigate the way in which these macromolecules make it possible for the long fibers of our nerve and muscle cells to conduct impulses. These integral components of cell membranes are marvels of nature's evolutionary adaptation. To understand them we must probe the boundaries of physics and chemistry. Since function is intimately related to structure, we examine the molecular structure of channels, focusing on physical principles that govern all matter. With the application of genetic methods, our knowledge of ion channels has broadened and deepened. In the hope that research can help ameliorate suffering, we discuss the diseases that arise from channel malfunctions due to genetic mutations.
Voltage-Gated Calcium Channels
Voltage-gated calcium channels are essential mediators of a range of physiological functions, including the communication between nerve Vcells, the regulation of heart beat, muscle contraction, and secretion of hormones such as insulin. Consequently, these channels are critical phar macological targets in the treatment of a variety of disorders, such as epi lepsy, hypertension, and pain. Voltage-gated calcium channels have there fore been subject to intense study by numerous investigators over the past few decades, and an immense body of work has accumulated. In this book, we provide the first comprehensive overview of our current state of knowl edge concerning this exciting field of research. Leading off with a general review of calcium signaling and techniques to measure calcium channel ac tivity, the book delves into a provocative overview of the history of the cal cium channel field. A number of chapters are dedicated towards various aspects of calcium channel structure and function, including channel gat ing, permeation, modulation and interactions with members of the exo- totic machinery—contributed by both established leaders and rising stars in the field.
Voltage Stability of Electric Power Systems
The book describes practical methods that can be used for voltage security assessment and offers a variety of examples. This is a first attempt to condense the technical papers and reports on this subject into a single, coherent, and theoretically sound presentation.Transmission, generation, and load aspects of the voltage instability problem are treated in detail, and a comprehensive power system model for use in voltage stability analysis is developed and explained. Notions and concepts from nonlinear system theory are presented in a tutorial manner for the use of those new to the field.
Volcano Deformation : New Geodetic Monitoring Techniques
With contributions from some of the most experienced and knowledgeable experts in the field, the book desbribes the state-of-the-art techniques used by volcanologists to successfully predict volcanic eruptions. With chapters on GPS and synthetic aperture radar interferometry, Volcanic Deformation covers both the "classical" and emerging methodologies, and looks at the future challenges faced by scientists when predicting volcanic eruptions.
Volcanic Unrest : From Science to Society
Volcanic unrest is a complex multi-hazard phenomenon. The fact that unrest may, or may not lead to an imminent eruption contributes significant uncertainty to short-term volcanic hazard and risk assessment. Although it is reasonable to assume that all eruptions are associated with precursory activity of some sort, the understanding of the causative links between subsurface processes, resulting unrest signals and imminent eruption is incomplete. When a volcano evolves from dormancy into a phase of unrest, important scientific, political and social questions need to be addressed. This book is aimed at graduate students, researchers of volcanic phenomena, professionals in volcanic hazard and risk assessment, observatory personnel, as well as emergency managers who wish to learn about the complex nature of volcanic unrest and how to utilize new findings to deal with unrest phenomena at scientific and emergency managing levels.
Voices of Trauma : Treating Psychological Trauma Across Cultures
Synthesizing insights from psychiatry, social psychology, and anthropology, Voices of Trauma: Treating Survivors across Cultures sets out a framework for therapy that is as culturally informed as it is productive. An international panel of 23 therapists offers contextual knowledge on PTSD, coping skills, and other trauma sequelae as they affect survivors of traumatic events. Case studies from Egypt to Chechnya demonstrate various therapeutic approaches (and the Cultural Formation of Diagnosis from the DSM-IV), often integrated with social agencies outside the clinical setting. Authors explore the balance of inter- and intrapersonal factors in reactions to trauma, dispel misconceptions that hinder progress in treatment, and provide profound examples of mutual trust and empathy, even how the wounded may heal the therapist.
Voice controlled robotic arm
The study presents an innovative voice-controlled prosthetic hand for amputees below the elbow to retrieve some of the hand movements of their daily life. This light weight hand is designed to enable movement of the fingers as the user commands, using artificial intelligence (AI) and a Raspberry Pi 4 computer. A speech recognition algorithm is used to detect the spoken command from the user and send it to the AI module which then drives servomotors placed inside each finger of the prosthetic hand in order to give motion. With help of a mobile application that allows the user to insert new commands with different moves among other features.

VizSEC 2007 ; Proceedings of the Workshop on Visualization for Computer Security
Networked computers are ubiquitous, and are subject to attack, misuse, and abuse. One method to counteracting this cyber threat is to provide security analysts with better tools to discover patterns, detect anomalies, identify correlations, and communicate their findings. Visualization for computer security (VizSec) researchers and developers are doing just that. VizSec is about putting robust information visualization tools into the hands of human analysts to take advantage of the power of the human perceptual and cognitive processes in solving computer security problems.

Vitiligo
Vitiligo is an acquired pigmentary skin disorder caused by the absence of pigmentary cells from the epidermis that results in white macules and patches on the body. Initial lesions occur most frequently on the hands, forearms, feet, and face, favoring a periocular or perioral distribution. The course of the disease is often unpredictable and varies in response to the treatment. Depigmentation often the cause of psychological distress, social stigmatization, and low self-esteem...
