Описание: In this "beautiful, heartfelt, and ultimately important story about love, kinship, gratitude, and miracles" (Elizabeth Gilbert, #1 New York Times bestselling author), a beloved high school English teacher with terminal brain cancer undertakes a cross-country journey to reunite with his former students in order to find out if he made a difference and discovers what is truly important in life along the way. David Menasche lived for his work as a high school English teacher. His passion inspired his students, and between lessons on Shakespeare and sentence structure, he forged a unique bond with his kids, buoying them through personal struggles while sharing valuable life lessons. When brain cancer ultimately stole David's vision, memory, mobility, and--most tragically of all--his ability to continue teaching, he was devastated by the thought that he would no longer have the chance to impact his students' lives each day. But teaching was something Menasche just couldn't give up. Undaunted by the difficult road ahead of him, he decided to end his treatments and make life his classroom. He turned to Facebook with an audacious plan: a journey across America--by bus, by train, by red-tipped cane--in hopes of seeing firsthand how his kids were faring in life. Had he made a difference? Within forty-eight hours of posting, former students in more than fifty cities replied with offers of support and shelter. Traveling more than eight thousand miles from Miami to New York, and visiting hundreds of his students, David's fearless journey explores the things we all want and need out of life--family, security, independence, love, adventure--and forces us to stop to consider what truly matters in life. Evocative, moving, and inspirational, Priority List "is a rousing testimony to the ways in which, in the face of death, living fully in the present moment becomes possible" (Publishers Weekly).

Описание: The book summarises the outcom of a priority research programme: `Analysis, Modelling and Computation of Multiphase Flows`. The research comprises steady and unsteady multiphase flows in three frequently found reactor configurations, namely bubble columns without interiors, airlift loop reactors, and aerated stirred vessels.
Описание: This book contains the research report of the DFG Research Unit FOR 1845 (2014-2020) of the Universities of Bremen and Hannover. The thematic focus lies on speeding up ultra-precision machining technology by following a holistic approach to high-performance cutting. This includes ultra-precision milling at high spindle speeds (>10000 rpm), precision tool setting mechanisms for multi-cutting-edge diamond milling tools, magnetic levitation technology for high velocity feed axes, and dedicated control strategies for error identification and compensation at high speeds. Furthermore, automation and measurement aspects of the machine setup process especially for precision balancing of the spindle rotors are presented. Finally, it is demonstrated that how the developed technologies may be integrated into a common machine tool setup. The target audience primarily comprises research experts and practitioners in production engineering, but the book may also be of interest to graduate students alike.
