Global Food Security and Supply
With the global population projected to reach 9 billion by the year 2050, the need for nations to secure food supplies for their populations has never been more pressing. Finding better supply chain solutions is an essential part of achieving a secure and sustainable diet for a rapidly increasing population. We are now in a position, through methods including life cycle assessment (LCA), carbon footprinting and other tools, to accurately measure and assess our use – or misuse – of natural resources, including food. The impact of new technologies and management systems can therefore improve efficiencies and find new ways to reduce waste. Global Food Security and Supply provides robust, succinct information for people who want to understand how the global food system works. The book demonstrates the specific tools available for understanding how food supply works, addresses the challenges facing a secure and safe global food supply, and helps readers to appreciate how these challenges might be overcome. This book is a concise and accessible text that focuses on recent data and findings from a range of international collaborations and studies. The author provides both a snapshot of global food supply and security today, and a projection of where these issues may lead us in the future. This book will therefore be of particular interest to food policy leaders, commercial managers in the food industry, and researchers and students seeking a better understanding of a rapidly evolving topic.
Mechanics of Dislocation Fields
Accompanying the present trend of engineering systems aimed at size reduction and design at microscopic/nanoscopic length scales, Mechanics of Dislocation Fields describes the self-organization of dislocation ensembles at small length scales and its consequences on the overall mechanical behavior of crystalline bodies. The account of the fundamental interactions between the dislocations and other microscopic crystal defects is based on the use of smooth field quantities and powerful tools from the mathematical theory of partial differential equations. The resulting theory is able to describe the emergence of dislocation microstructures and their evolution along complex loading paths. Scale transitions are performed between the properties of the dislocation ensembles and the mechanical behavior of the body. Several variants of this overall scheme are examined which focus on dislocation cores, electromechanical interactions of dislocations with electric charges in dielectric materials, the intermittency and scale-invariance of dislocation activity, grain-to-grain interactions in polycrystals, size effects on mechanical behavior and path dependence of strain hardening.
Timed Arrays. Wideband and Time Varying Antenna Arrays
Introduces timed arrays and design approaches to meet the new high performance standards The author concentrates on any aspect of an antenna array that must be viewed from a time perspective. The first chapters briefly introduce antenna arrays and explain the difference between phased and timed arrays. Since timed arrays are designed for realistic time-varying signals and scenarios, the book also reviews wideband signals, baseband and passband RF signals, polarization and signal bandwidth. Other topics covered include time domain, mutual coupling, wideband elements, and dispersion. The author also presents a number of analog and digital beamforming networks for creating and manipulating beams. The book concludes with an overview of the methods to integrate time delay into the array design and of several other adaptive arrays that prove useful in many different systems. Examines RF signal concepts such as polarization and signal bandwidth and their applications to timed antenna arrays Covers arrays of point source, elements in timed antenna arrays, active electronically scanned array technology, and time delay in corporate fed arrays Includes complete design examples for placing time delay in arrays Timed Arrays: Wideband and Time Varying Antenna Arrays is written for practicing engineers and scientists in wireless communication, radar, and remote sensing as well as graduate students and professors interested in advanced antenna topics.
Menschen und ihre Materialien. Von der Steinzeit bis heute
Was verandert die Welt? Wer hat denn nun die Welt am starksten verandert: die Politiker, die Ideen in die Tat umsetzten, oder die Philosophen, von denen sie stammten? Oder vielleicht sogar jemand ganz anderes? Etwa der Erfinder des Papiers, ohne das weder Buchdruck noch Reformation denkbar waren? Oder auch diejenigen, die Eisen und Bronze hervorbrachten und damit ganze Epochen begrundeten. Dieses Buch belegt eindrucksvoll: Unsere Geschichte ist immer auch die der Materialien, die wir verwenden. Geschichte neu geordnet Systematisch geht der Autor der Frage nach, wie die Entwicklung von Kulturen und die Moglichkeiten der Materialherstellung zusammenhangen. Er durchstreift die Jahrtausende und setzt dabei bestimmte Zeiten und Materialgruppen zueinander in Beziehung. Dabei beleuchtet er nicht zuletzt spannende Details von Herstellung und Verarbeitung. Alternative Realitaten Und auch Gedankenspielen gibt das Buch Raum, denn die Frage >Was ware wenn?< beendet jedes seiner Kapitel. Unterhaltsam und lehrreich sind diese Spekulationen uber einen moglichen Gang der Dinge fur den Fall, dass es bestimmte Materialinnovationen nicht gegeben hatte. In diesen Passagen wird besonders deutlich, wie gro? die Bedeutung des >materiellen< Aspekts von Geschichte ist – ohne den im Ubrigen auch solche Errungenschaften wie Kunst und moderne Medizin undenkbar waren.
