Es sei allerlei für die Nationalbibliothek zu ergattern, meinte Generaldirektor Paul Heigl im Jänner 1944 in einem Brief an einen Kollegen. So lässt sich der umfangreiche Bücherraub, der die Geschichte der Nationalbibliothek in Wien zwischen 1938 und 1945 prägte, in wenigen Worten umreißen. Die größte wissenschaftliche Bibliothek in Österreich und nach dem "Anschluss" im März 1938 drittgrößte im Deutschen Reich nutzte ihre dominierende Stellung in der Bibliothekslandschaft, um ihre Bestände mit Raubgut zu vermehren. Durch die Person des 1938 eingesetzten Generaldirektors und engagierten Nationalsozialisten Paul Heigl, durch seine vielen Verbindungen zum NS-Staat, gelangten im Zeitraum 1938 bis 1945 bis zu einer halben Million geraubte Bücher in die Bibliothek am Josefsplatz. Nach jahrzehntelangem Verschweigen der eigenen NS-Geschichte in offiziellen Bibliothekspublikationen wird hier erstmals die aktive Rolle geschildert, die die Bibliothek bei unrechtmäßigen Erwerbungen spielte. Der Bücherraub privater und institutioneller Bibliotheken im In- und Ausland kann dank des umfangreichen ÖNB-Archivs ausführlich dargestellt werden. Darüber hinaus werden die Bemühungen der Nationalbibliothek - sowohl in den Nachkriegsjahren als auch in jüngster Zeit - um die Ausforschung und die Restitution von geraubten Objekten dokumentiert. Diese Geschichte will aber nicht nur auf unrechtmäßige Zugänge fokussieren, sondern auch den Versuch unternehmen, den Alltag in der Bibliothek in der NS-Zeit einzufangen. Sie versteht sich als Beitrag zur bislang kaum behandelten Geschichte des Bibliothekswesens in Österreich in den Jahren 1938 bis 1945 und spiegelt gleichzeitig auch die politische Geschichte Österreichs im 20. Jahrhundert wider.

L'historiographie révolutionnaire a sévèrement jugé 1795. Réaction bourgeoise, recul de la démocratie, ingérence militaire : autant de remises en cause qui ont pu justifier la condamnation du moment thermidorien. La succession de nos expériences républicaines nous incite aujourd'hui à repenser l'an III en termes moins exclusifs. En 1795, par-delà la répression de Prairial, la République demeure. La permanence des hommes et des principes en répond. Encore convient-il de la préserver de nouveau...

According to the World Health Organization, more than 40 million people in the world are affected with dementia. To date, 60-70% of the cases of dementia are attributed to the Alzheimer's disease (AD). This neurodegenerative disorder gradually takes place over a period of at least 20 years before the onset of symptoms, which are impaired memory, apathy and depression. The characteristics of AD consist in neurofibrillary tangles (intraneuronal aggregates of hyperphosphorylated tau proteins) and senile plaques (dense extraneuronal deposits composed of amyloid ß (Aß)). The other features linked to these two core pathological hallmarks of AD are inflammation, oxidative stress, progressive synaptic and neuronal loss. In past years, some of the emerging therapeutic strategies against AD were employed to deal with the pathological hallmarks of the disease. Science teams all over the world try to restore the tau phosphorylation equilibrium. Their purpose is to interfere with the aggregation of tau and decrease its amount of proteins per se as well. Furthermore, they are trying either to stimulate the elimination processes of the aggregated tau proteins or to stop the formation of Aß peptides. This could be reached by the stimulation of the classic techniques of protein degradation such as the autophagic pathway, or by the targeted immunotherapy. In this Research Topic, we wish to summarize and review the etiology of AD and the related therapeutic opportunities for the next decades. To fully understand the precise mechanisms underlying AD, research findings, reviews, new insights and new approaches include AD and related tauopathies, tau phosphorylation balance, pharmacological compounds against AD, neuroprotection strategies and new therapeutic ways but also risk factors for AD and AD genetic information are included in this issue.

3D Bioprinting and Nanotechnology in Tissue Engineering provides an in depth introduction to these two technologies and their industrial applications. Stem cells in tissue regeneration are covered, along with nanobiomaterials. Commercialization, legal and regulatory considerations are also discussed in order to help you translate nanotechnology and 3D printing-based products to the marketplace and the clinic. Dr. Zhang’s and Dr. Fishers’ team of expert contributors have pooled their expertise in order to provide a summary of the suitability, sustainability and limitations of each technique for each specific application. The increasing availability and decreasing costs of nanotechnologies and 3D printing technologies are driving their use to meet medical needs, and this book provides an overview of these technologies and their integration. It shows how nanotechnology can increase the clinical efficiency of prosthesis or artificial tissues made by bioprinting or biofabrication. Students and professionals will receive a balanced assessment of relevant technology with theoretical foundation, while still learning about the newest printing techniques.

• Includes clinical applications, regulatory hurdles, and risk-benefit analysis of each technology.
• This book will assist you in selecting the best materials and identifying the right parameters for printing, plus incorporate cells and biologically active agents into a printed structure
• Learn the advantages of integrating 3D printing and nanotechnology in order to improve the safety of your nano-scale materials for biomedical applications

This book focuses on LTE with full updates including LTE-Advanced (Release-11) to provide a complete picture of the LTE system.  Detailed explanations are given for the latest LTE standards for radio interface architecture, the physical layer, access procedures, broadcast, relaying, spectrum and RF characteristics, and system performance.
