"Since 2012, the subsequent reinforcement of reinforced concrete components with bonded reinforcement has been regulated in a separate guideline. This includes the dimensioning of the adhesively bonded strips made of carbon fiber reinforced plastic (CFRP), which, in addition to the complex iterative bending design, have a very complex bonding behavior. For this purpose, the German Committee for Structural Concrete developed a model for the verification based on experimental evaluations, in which the occurring tensile forces are partly transferred into the component via intermediate elements (partial distances between flexural cracks). Simultaneously, simplified but more inaccurate verification formats were made available to reduce the complexity of the verification. For an early assessment of the use of bonded CFRP strips, different tools have been developed in this paper for reinforced concrete components with a rectangular cross-section depending on the different verification formats. For this purpose, the design parameters were considered separately for pure bending strength and bonding behavior. For a simple calculation, tables for the design with dimensionless coefficients were obtained by analogy with the reinforced concrete construction, with which the required cross-section area for the CFRP strips can be determined by means of a limited stretching from the simplified verification of the flexural load bearing capacity. For a more economical solution, the more precise verification of the force transmission on the intermediate elements was configured in an Excel workbook, because this results in an extraordinary iterative calculation effort.".

A history of Austria's Chambers of Engineers This book is the first history of Austria's Chambers of Chartered Engineering Consultants from the foundation of the institution of chartered engineering consultants in 1860 up to the Ziviltechnikergesetz of 1957. In addition to tracing the history of the organization, the book tackles head-on the controversial issue of collaboration with the Nazi regime and the fate of those chartered engineering consultants who were persecuted. Selected biographies reveal the extent of the chambers' autonomy and show how members' careers were made and broken during this period, as well as discriminatory measures. A special concern of this book is to keep alive the memory of those chartered engineering consultants who fell victim to the Nazi regime. With this thorough and scientific reappraisal, Austria's Federal Chamber of Chartered Engineering Consultants has taken an important step in taking responsibility for its own history. An important contribution to the historical reappraisal of the Nazi period and the history of Austria's institutions Selected biographies of chartered engineering consultants With contributions by Ingrid Holzschuh, Inge Korneck, and Alexandra Wachter, as well as numerous historical illustrations and infographics Über die Geschichte der österreichischen Ingenieurkammern Das vorliegende Buch untersucht erstmals die Geschichte der österreichischen Ingenieurkammern und ihrer Mitglieder von der Gründung des Ziviltechnikerwesens 1860 bis zum Ziviltechnikergesetz 1957. Der Fokus liegt neben der Rekonstruktion der Organisationsgeschichte auf der Aufarbeitung der Kollaboration mit dem NS-Regime und dem Schicksal jener Ziviltechniker:innen, die verfolgt wurden. Ausgewählte Biografien machen Handlungsspielräume innerhalb der Kammern, Karriereverläufe und -brüche von Mitgliedern und Auswirkungen diskriminierender Maßnahmen sichtbar. Ein besonderes Anliegen ist dabei, die Erinnerung an jene Ziviltechniker:innen wachzuhalten, die dem NS-Regime zum Opfer fielen. Mit der wissenschaftlichen Aufarbeitung der Kammergeschichte übernimmt die Bundeskammer der Ziviltechniker:innen eine wichtige Verantwortung. Ein zentraler Beitrag zur Aufarbeitung der NS-Zeit und der Institutionengeschichten in Österreich Wissenschaftliche Aufarbeitung exemplarischer Biografien von Ziviltechniker:innen Mit Beiträgen von Ingrid Holzschuh, Inge Korneck und Alexandra Wachter sowie mit zahlreichen historischen Abbildungen und Infografiken

The confluence of the Green and Colorado Rivers, now in Canyonlands National Park, near popular tourist destination Moab, still cannot be reached or viewed easily. Much of the surrounding region remained remote and rarely visited for decades after settlement of other parts of the West. The first U.S. government expedition to explore the canyon country and the Four Corners area was led by John Macomb of the army's topographical engineers.The soldiers and scientists followed in part the Old Spanish Trail, whose location they documented and verified. Seeking to find the confluence of

J.E. Moyal has been pronounced 'one of Australia's most remarkable thinkers'. Yet, he was, essentially, a scientific maverick. Educated in a modest high school in Tel Aviv, he took himself to France to train as an engineer, statistician and mathematician and escaped to England as France fell. It was from outside academia that he entered into communication with the 'high priest' of British theoretical physics, P.A.M. Dirac, challenging him with the idea of a statistical basis of quantum mechanics. Their correspondence forms the core of this book and opens up an important and hitherto unknown chapter for physicists, mathematicians and historians of science. Moyal's classic paper, 'A statistical basis for quantum mechanics', also reproduced here in full, has come to underlie an explosion of research and to underpin an array of major technological developments. Joe Moyal emerges in this small biography as a witty and intrepid character, a scuba diver and wine connoisseur, a generous teacher and researcher, and a man whose academic life-spanning France, Ireland, Britain, the USA and Australia-intersected with some of the leading scientists of the 20th century.
