This book was released on 2021-09-20 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2nd edition of this book incorporates the tremendous clinical advances that have occurred in the field of transcranial direct current stimulation (tDCS) over the past 5 years. Since the 1st edition was published, the clinical use of tDCS has moved from its infancy, and is now in a thrilling new phase with numerous possibilities as well as challenges. tDCS is a technique that excels in terms of safety and tolerability, and within a few years, novel technological developments will allow its use at home. At the same time, large, phase III trials have been exploring the clinical efficacy of tDCS, the results of which have been published in leading journals such as the New England Journal of Medicine and JAMA Psychiatry. This 2nd edition summarizes the state of the art of the field. Written by leading experts in the field, the book is divided into 5 parts: Introduction and Mechanisms of Action; Research Methods; tDCS in the life cycle; Applications of tDCS in neuropsychiatric disorders (further divided into Psychiatry and Neurology); and The clinical use of tDCS. It also includes several new chapters, covering topics such as precision stimulation of tDCS; combination of tDCS with different neuroimaging modalities; and use of tDCS in new clinical conditions. Moreover, all chapters have been rewritten and updated. This book will be of significant interest to psychiatrists, neurologists and neuroscientists new to the field as well as those with a background in tDCS who want to increase their understanding of particular psychiatric conditions.

Download or read book Power Transmission by Direct Current written by E. Uhlmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The direct current transmission scheme linking the island of Gotland to the main land of Sweden by means of a submarine cable under the Baltic Sea is the first commercial realisation of a modern technique for the transmission of electrical energy. It is certainly not accidental that this pioneering initiative was allotted to the Gotland scheme. Various viewpoints may be presented regarding this, but the essential factor relates to the circumstances that permitted the magnitude ofthe transmitted power to be given a value which would not have been technically or economically feasible for any other project. The power, on the one hand, was sufficiently small to justify the risk associated with such a new venture, for it fell within limits acceptable both to ASEA as the manufacturer and to the Swedish State Power Board as the customer. On the other hand, the power was large enough to demonstrate the technical and economic characteristics of the new system and to provide the opportunity of gaining invaluable experience that could be applied to future large-scale transmission systems. In 1954 a team under the direction of Dr. Uno Lamm successfully commissioned the Gotland scheme, representing the culmination of many years of intensive development work.
Download or read book Transcranial Direct Current Stimulation in Neuropsychiatric Disorders written by André Brunoni and published by Springer. This book was released on 2016-09-12 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide a comprehensive review of the use of Transcranial Direct Current Stimulation (tDCS) in different psychiatric conditions. Here we review tDCS clinical studies employing different types of design (from single-session tDCS studies to randomized clinical trials) as well as studies evaluating the impact of tDCS in neurophysiological, behavioral and brain imaging outcomes. Although the understanding about physiological foundations and effectiveness of clinical therapies of psychiatric diseases has been considerably increased during the last decades, our knowledge is still limited, and consequently psychiatric diseases are still a major burden to the individual patient and society. Recently, interest in pathological alterations of neuroplasticity in psychiatric diseases as a critical condition for development, and amelioration of clinical symptoms increased, caused by the fact that new tools, such as functional imaging, and brain stimulation techniques do allow to monitor, and modulate these phenomena in humans. Especially non-invasive brain stimulation techniques evolved as an attractive potential new therapeutic tool. The interest in non-invasive brain stimulation has grown exponentially in the past 25 years, with the development of non-pharmacological, neuromodulatory techniques such as tDCS and repetitive transcranial magnetic stimulation (rTMS). TDCS, although even newer than rTMS, has attracted considerable attention in both basic and clinical research scenarios. In the context of clinical research, tDCS is being increasingly investigated as a novel treatment tool for several psychiatric disorders, such as major depression, schizophrenia and neurocognitive and substance abuse disorders. Transcranial Direct Current Stimulation in Neuropsychiatric Disorders – Clinical Principles and Management intends to serve as a practical guide on the field, attracting the interest of psychiatrists, neurologists and neuroscientists with little or no experience with tDCS, as well as those with a background on tDCS who want to increase their knowledge in any particular psychiatric condition.

Download or read book The Interplay between European Merger Control Law and the Liberalisation of European Electricity Natural Gas and Petroleum Markets written by Henning Matthiesen and published by GRIN Verlag. This book was released on 2023-04-21 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2020 in the subject Law - European and International Law, Intellectual Properties, grade: 2,2, Leuphana Universität Lüneburg (Fakultät Wirtschaftswissenschaften), language: English, abstract: This doctoral thesis examines how European merger control law is applied to the energy sector and to which extent its application may facilitate the liberalisation of the electricity, natural gas and petroleum industries so that only those concentrations will be cleared that honour the principles of the liberalisation directives. In 2007, the Commission emphasized that a real internal European energy market is essential to meet Europe’s three energy objectives. These were for example competitiveness to cut costs for citizens and undertakings to foster energy efficiency and investment, sustainability including emissions trading, and security of supply with high standards of public service obligations. The EU issued three pre-liberalisation directives since the 1990s. Dissatisfied with the existing monopolistic structures, in Germany through demarcation and exclusive concession agreements for the supply of electricity and natural gas, which were until 1998 exempted from the cartel prohibition provision, and the prevalence of exclusive rights on the energy markets, the Commission triggered infringement proceedings against four Member States. The CJEU confirmed that the Commission has the power to abolish monopoly rights under certain circumstances and the rulings had the effect of convincing the member states to enter into negotiations for an opening up of energy markets owing to the internal market energy liberalization directives 1996 / 1998 / 2003 / 2009 / 2019. The 2nd liberalisation package of 2003 brought a widening of market opening and acceleration of pace of market opening to a greater number of eligible customers and an increase in the provisions on management and legal unbundling. The 3rd energy package of 2009 addressed ownership unbundling of key-infrastructure ownership and energy wholesale and retail supply consisting of three regulations and two directives. The 4th liberalization package inter alia consists of a new IEMD2019 and IGMD2019 and addresses energy efficiency and rules on good governance in the Energy Union. A brief analysis of the economic implications of concentrations is followed by an assessment of the evolution of European merger control law since 1989, 1997 and 2004. Then, the theoretical findings are contrasted to the results of recent merger proceedings in the energy sector.
