Endoscopic spinal surgery has become popular due its procedure-related benefits. The biportal endoscopic surgery is a recent technique, which has gained popularity in Asia, Europe, and Latin America since it can be applied to treat many diseases of the whole spine as cervical, thoracic, lumbar and sacral. Divided into thirty-four chapters, this first-ever book on unilateral biportal endoscopic spine surgery presents the technique history review and its current applications; the currently available technology and basic principles of this surgery: anesthesia, position, and operative room setup; endoscopic instruments, hydrostatic pressure, and intraoperative radiology; as well as anatomical considerations of basic approaches. It also details the techniques to resolve lumbar, cervical and thoracic spine diseases. Written by the world's most influential groups that perform the method, Unilateral Biportal Endoscopy of the Spine: An Atlas of Surgical Techniques will certainly be widely accepted by all surgeons interested to improve their daily practice in minimally invasive spine surgery.

Multimedia artist Clifford Ross looks beyond the natural world to uncover a world bound only by the imagination, much like in Lewis Carroll's Through the Looking Glass. Images are reversed and landscapes reimagined. Ross uses old and new methods to produce exceptionally beautiful and radically redesigned conceptions of reality, presenting his own digital vision.

This book addresses the multiple technical aspects of thedistribution of synchronization in new generation telecommunicationnetworks, focusing in particular on synchronous Ethernet andIEEE1588 technologies. Many packet network engineers struggle withunderstanding the challenges that precise synchronizationdistribution can impose on networks. The usual “why”,“when” and particularly “how” can causeproblems for many engineers. In parallel to this, some othermarkets have identical synchronization requirements, but with theirown design requirements, generating further questions. This bookattempts to respond to the different questions by providingbackground technical information. Invaluable information on stateof-the-art packet network synchronization and timing architecturesis provided, as well as an unbiased view on the synchronizationtechnologies that have been internationally standardized overrecent years, with the aim of providing the average reader (who isnot skilled in the art) with a better understanding of this topic.The book focuses specifically on synchronous Ethernet and IEEE 1588PTP-based technologies, both key developments in the world ofsynchronization over the last 10 years. The authors address theneeds of engineers and technical managers who are struggling withthe subject of synchronization and provide an engineering referencefor those that need to consider synchronization in NGN. The marketapplications that are driving the development of packet networksynchronization and timing architectures are also discussed. Thisbook provides a wide audience with everything they need to knowwhen researching, implementing, buying and deploying packetsynchronization architectures in telecommunication networks. Contents 1. Network Evolutions, Applications and Their SynchronizationRequirements. 2. Synchronization Technologies. 3. Synchronization Network Architectures in Packet Networks. 4. Synchronization Design and Deployments. 5. Management and Monitoring of Synchronization Networks. 6. Security Aspects Impacting Synchronization. 7. Test and Measurement Aspects of Packet SynchronizationNetworks. Appendix 1.Standards in Telecom Packet Networks Using SynchronousEthernet and/or IEEE 1588. Appendix 2.

Herausgegeben im Auftrag des Auswärtigen Amts vom Institut für Zeitgeschichte. Hauptherausgeber: Horst Möller, Mitherausgeber: Gregor Schöllgen Wissenschaftliche Leiterin: Ilse Dorothee Pautsch Für die Bundesrepublik war 1962 ein schwieriges Jahr, das in der Kuba-Krise und der "Spiegel-Affäre" gipfelte. Die Verhandlungen über eine europäische politische Union scheiterten, der Beitritt Großbritanniens zur EWG blieb ungeklärt. Während gegenseitige Staatsbesuche die deutsch-französische Aussöhnung besiegelten, war das Verhältnis zu den USA belastet: Amerikanische Vorschläge gegenüber der UdSSR zur Lösung der Berlin-Frage erweckten Misstrauen in Bonn. Unterschiedliche Überlegungen zur Ausstattung der NATO mit Atomwaffen und zu deren Einsatz sorgten für weitere Reibungspunkte. Seite an Seite fanden sich die Bündnispartner jedoch angesichts der Bedrohung in Kuba: Sie wurde zum Testfall für die Entschlossenheit, dem sowjetischen Expansionsdrang Widerstand entgegenzusetzen.

In April-May 1940 the German Wehrmacht invaded Northern and Western Europe. The subsequent occupation of Norway, Denmark, the Netherlands, Belgium, Luxembourg, and France brought the Jewish population of these countries – both established residents and refugees – under German control. From autumn 1941 in Luxembourg and from spring/summer 1942 in Belgium, the Netherlands and occupied France, Jews were required to wear the ‘Jewish star’ and many were subjected to forced labour. By mid-1942, deportations from Luxembourg and France to the ghettos and extermination camps in occupied Eastern Europe had already begun, while in the other occupied countries they were imminent. In April 1942 Alfred Oppenheimer, the Jewish elder in Luxembourg, wrote: ‘A dreadful fate hangs over our community again. The worst that can happen has now happened and the Poland transport is a certainty.’ This volume covers Norway and Western Europe during the period from the German invasion to mid 1942 (developments in Denmark for this period are documented in vol. 12) and records how Jews in these parts of Europe were excluded from society and stripped of their rights, livelihoods, and property. Letters and diary entries by the persecuted Jews detail life under German occupation and the attempts by many Jews to emigrate. The sources show how Jewish organizations sought to alleviate the impact of persecution, and how the German occupiers and local collaborators targeted Jews with increasingly stringent measures and clamped down on any form of resistance.

Are you a Reluctant Metaphysician? A career change, an upsetting external event, a serious illness, a painful breakup, or an unravelling culture can all be invitations to enter a deeper world behind the world. You may not have chosen to go there, but you evolve thereby. This book weaves together stories and reflections to introduce teachings and practices from ancient wisdom traditions that illuminate our unique life path.The Path of a Reluctant Metaphysician speaks to the importance of a holistic spiritual philosophy in our current times of the "great unraveling" of our political, economic, cultural, and ecological world. Here you will find an approach to finding your life stance in such troubled times. The metaphysical path is an "all vector approach" that incorporates both "spiritual" and "soulful" pathways, traditions of postural initiation such as Tai Chi, mythology, depth psychology, bodymind healing methods, a non-deterministic approach to astrology, and a multi-dimensional approach to the political sphereDr. Mayer transmits stories, teachings, and practices from his multifaceted career that are so captivating, they may lead you to reluctantly take time out of your busy everyday life. Be forewarned if you read this book you too may become a Reluctant Metaphysician! Kirkus Reviews says: "A meaningful contribution to the spiritual self-help library...A psychologist blends spiritual paths from the East, West, and beyond for an innovative approach to healing...an expansive tale told with humility and insight." Larry Dossey, MD says, Dr. Mayer's revelations in various metaphysical domains are a guide for anyone who desires a richer and more fulfilling experience of life. If you think life must contain more juice than you have known so far, this book is for you.

The Path of a Reluctant Metaphysician

Inspiriert von Andrej Tarkowskijs Filmkunst versucht dieses Buch, das Kino der Moderne als Ort einer Konversion von Subjektivität lesbar zu machen - als Ort, wo die Akteure des Films wie auch die Rezipienten des Kinos eine »Mutation« durchlaufen, eine radikale Verwandlung ihres Selbst- und Weltverhältnisses. Motive wie Melancholie, Langeweile, Leiden an Zeit und Erschöpfung gelten dabei als Vorzeichen eines »schwachen Subjekts«. Michael Mayer macht Gilles Deleuzes Begriff des Zeit-Bildes als praktische Kategorie erkennbar, bei der die Spezifik des Filmbildes auf das »schwache Vermögen« seiner Wahrnehmbarkeit verweist - und er zeigt: Diese Wahrnehmung ist die der Passibilität.
