Download or read book Stone Tools in Transition From Hunter Gatherers to Farming Societies in the Near East written by Borrell, Ferran and published by Servei de Publicacions de la Universitat Autònoma de Barcelona. This book was released on 2013 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume compiles the papers presented at the seventh edition of the Conference on PPN Chipped and Ground Stone Industries of the Fertile Crescent, held in Barcelona from 14 to 17 February 2012. This series of conferences/workshops started nineteen years ago - the first meeting was organised in Berlin in 1993 - and is devoted to the study of the lithic record in the Pre-Pottery Neolithic of the Near East and neighbouring regions. The seventh of these conferences was organised by the Institució Milà i Fontanals (Consejo Superior de Investigaciones Científicas) and the Prehistory Department (Universitat Autònoma de Barcelona). This volume includes a total number of 36 articles, covering a wide range of topics and disciplines related to lithic studies in the Levant over a long chronological time span (from the final stages of the Epipalaeolithic/Natufian to the Halaf period). The publication of the conference proceedings is thus an interesting synthesis of the current state of lithic studies on the Pre-Pottery Neolithic of the Near East, and consolidates this specific series of conferences as a key tool to maintain and stimulate the vitality of high quality research into the Near Eastern lithic record.

Download or read book Industrial Drying Systems written by J E 'Ed' Smith and published by Springer Nature. This book was released on 2023-06-23 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book stands as a manual and ready reference for the range of professionals involved in industrial drying. It addresses problems connected with most industrial drying systems, too often designed by those with limited formal engineering training in an environment of minimal regulatory oversight. The author explains how many existing drying systems are dangerous and pose fire hazards, create unhealthy working conditions, are highly energy inefficient, and have very little to no primary modeling of key process variables. Equipping readers with the necessary competencies to contend with issues in conducting studies, developing new designs; manufacturing, installing, and servicing industrial drying systems, this volume is ideal for engineers, OEMS, contractors, service technicians, scientists; agriculture, food, wood products manufacturers; and insurance underwriters.

Download or read book Flight Theory and Aerodynamics written by Charles E. Dole and published by John Wiley & Sons. This book was released on 2016-11-07 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pilot's guide to aeronautics and the complex forces of flight Flight Theory and Aerodynamics is the essential pilot's guide to the physics of flight, designed specifically for those with limited engineering experience. From the basics of forces and vectors to craft-specific applications, this book explains the mechanics behind the pilot's everyday operational tasks. The discussion focuses on the concepts themselves, using only enough algebra and trigonometry to illustrate key concepts without getting bogged down in complex calculations, and then delves into the specific applications for jets, propeller crafts, and helicopters. This updated third edition includes new chapters on Flight Environment, Aircraft Structures, and UAS-UAV Flight Theory, with updated craft examples, component photos, and diagrams throughout. FAA-aligned questions and regulatory references help reinforce important concepts, and additional worked problems provide clarification on complex topics. Modern flight control systems are becoming more complex and more varied between aircrafts, making it essential for pilots to understand the aerodynamics of flight before they ever step into a cockpit. This book provides clear explanations and flight-specific examples of the physics every pilot must know. Review the basic physics of flight Understand the applications to specific types of aircraft Learn why takeoff and landing entail special considerations Examine the force concepts behind stability and control As a pilot, your job is to balance the effects of design, weight, load factors, and gravity during flight maneuvers, stalls, high- or low-speed flight, takeoff and landing, and more. As aircraft grow more complex and the controls become more involved, an intuitive grasp of the physics of flight is your most valuable tool for operational safety. Flight Theory and Aerodynamics is the essential resource every pilot needs for a clear understanding of the forces they control.
