The New Yorker's award-winning war correspondent returns to his own country to chronicle its accelerating civic breakdown, in an indelible eyewitness narrative of startling explanatory powerAfter years of living abroad and covering the Global War on Terrorism, Luke Mogelson went home in early 2020 to report on the social discord that the pandemic was bringing to the fore across the US. An assignment that began with right-wing militias in Michigan soon took him to an uprising for racial justice in Minneapolis, then to antifascist clashes in the streets of Portland, and ultimately to an attempted insurrection in Washington, D.C. His dispatches for The New Yorker revealed a larger story with ominous implications for America. They were only the beginning.This is the definitive eyewitness account of how—during a season of sickness, economic uncertainty, and violence—a large segment of Americans became convinced of the need to battle against dark forces plotting to take their country away from them. It builds month by month, through vivid depictions of events on the ground, from the onset of COVID-19 to the attack on the US Capitol—during which Mogelson followed the mob into the Senate chamber—and its aftermath. Bravely reported and beautifully written, The Storm Is Here is both a unique record of a pivotal moment in American history and an urgent warning about those to come.

Jan Kortmann untersucht in diesem Buch, ob der Gesundheitsschutz und die Recyclingfähigkeit potenzielle Markteintrittsbarrieren für den Verbundbaustoff Carbonbeton darstellen. Für die Fragestellung, ob Carbonbeton wiederverwendet werden kann, wurden Recyclingverfahren analysiert und Verwertungsoptionen für die anfallenden Materialfraktionen aufgezeigt. Zur Sicherstellung des Gesundheitsschutzes wurden Faseremissionen aus Ver- und Bearbeitung von Carbonbeton erhoben und das Gesundheitsgefährdungspotenzial beurteilt.

This book contains the proceedings of the fib Symposium “High Tech Concrete: Where Technology and Engineering Meet”, that was held in Maastricht, The Netherlands, in June 2017. This annual symposium was organised by the Dutch Concrete Association and the Belgian Concrete Association. Topics addressed include: materials technology, modelling, testing and design, special loadings, safety, reliability and codes, existing concrete structures, durability and life time, sustainability, innovative building concepts, challenging projects and historic concrete, amongst others.The fib (International Federation for Structural Concrete) is a not-for-profit association committed to advancing the technical, economic, aesthetic and environmental performance of concrete structures worldwide.

This book introduces an analytic method to describe the shadow of black holes. As an introduction, it presents a survey of the attempts to observe the shadow of galactic black holes. Based on a detailed discussion of the Plebański–Demiański class of space-times, the book derives analytical formulas for the photon regions and for the boundary curve of the shadow as seen by an observer in the domain of outer communication. It also analyzes how the shadow depends on the motion of the observer. For all cases, the photon regions and shadows are visualized for various values of the parameters. Finally, it considers how the analytical formulas can be used for calculating the horizontal and vertical angular diameters of the shadow, and estimates values for the black holes at the centers of our Galaxy near Sgr A• and of the neighboring galaxy M87.

Particularly in the humanities and social sciences, festschriften are a popular forum for discussion. The IJBF provides quick and easy general access to these important resources for scholars and students. The festschriften are located in state and regional libraries and their bibliographic details are recorded.
