An experimental investigation to determine the relative merits of bronze and nodular iron as cage materials for cylindrical-roller bearings was conducted using four identical 75-millimeter-bore outer-race-riding cage-type cylindrical-roller bearings (tow with bronze cages and two with nodular iron cages). The test bearings were operated over a range of DN values (product of bearing bore in mm and shaft speed in rpm) from 300,00 to 2,100,000, oil flows from 2 to 8 pounds per minute, and loads from 7 to 1613 pounds.
The 3rd edition of this successful textbook continues to build on the strengths that were recognized by a 2008 Textbook Excellence Award from the Text and Academic Authors Association (TAA). Materials Chemistry addresses inorganic-, organic-, and nano-based materials from a structure vs. property treatment, providing a suitable breadth and depth coverage of the rapidly evolving materials field — in a concise format. The 3rd edition offers significant updates throughout, with expanded sections on sustainability, energy storage, metal-organic frameworks, solid electrolytes, solvothermal/microwave syntheses, integrated circuits, and nanotoxicity. Most appropriate for Junior/Senior undergraduate students, as well as first-year graduate students in chemistry, physics, or engineering fields, Materials Chemistry may also serve as a valuable reference to industrial researchers. Each chapter concludes with a section that describes important materials applications, and an updated list of thought-provoking questions.
The unforgettable memoir of 70 years of contemporary and personal history from the great French filmmaker, journalist and intellectual Claude Lanzmann Born to a Jewish family in Paris, 1925, Lanzmann's first encounter with radicalism was as part of the Resistance during the Nazi occupation. He and his father were soldiers of the underground until the end of the war, smuggling arms and making raids on the German army. After the liberation of France, he studied philosophy at the Sorbonne, making money as a student in surprising ways (by dressing as a priest and collecting donations, and stealing philosophy books from bookshops). It was in Paris however, that he met Jean-Paul Sartre and Simone de Beauvoir. It was a life-changing meeting. The young man began an affair with the older de Beauvoir that would last for seven years. He became the editor of Sartre's political-literary journal, Les Temps Modernes—a position which he holds to this day—and came to know the most important literary and philosophical figures of postwar France. And all this before he was 30 years old. Written in precise, rich prose of rare beauty, organized—like human recollection itself—in interconnected fragments that eschew conventional chronology, and describing in detail the making of his seminal film Shoah, The Patagonian Hare becomes a work of art, more significant, more ambitious than mere memoir. In it, Lanzmann has created a love song to life balanced by the eye of a true auteur.
