This book takes a broad and eclectic view of the water that all humanity depends upon, probing its role in human life and in the history of our planet, as well as surveying the latest scientific understanding of purification techniques and standards for the protection of water quality. The volume opens with a chapter on the role of drinking water in human life, which discusses the planet’s water resources, the quality of drinking water, water and health, the advent of water quality standards, “Green” chemistry and more. The chapter concludes by discussing the relationship of the biosphere and human civilization. Chapter Two explores the unique properties of water, the role of water in ...
Exactly ten years ago an experiment was started that proved to be extremely successful: the First Gothenburg Symposium. Its intent was to further the under standing of all processes pertaining to Chemical Water and Wastewater Treatment, and to bring together specialists working in basic research as well as in devel opment and administration. Now, the Proceedings of the Sixth Symposium are about to be published, clearly proving that there is a need for this forum. They dramatically illustrate the significance and the dynamic development of the topics of these symposia. It is fascinating to witness that in this time of reduced economic growth or even standstill, the environmental drive has not...
"Examining an important, rising trend in today's global system, Citizenship 2.0 does us a fine service in exploring the origins and consequences of the dual citizenship phenomenon."--Alejandro Portes, Princeton University.sity.
Kälin and Kochenov's Quality of Nationality Index (QNI) ranks the objective value of all nationalities as legal statuses of attachment to states. Using a wide variety of strictly quantifiable data to gauge the opportunities presented and limitations imposed by nationalities on their holders, the QNI provides a comprehensive ranking of the intrinsic quality of each citizenship status in the world. Both the internal value (economic opportunities, human development and peace and stability) and the external value (including the number and quality of visa-free travel and, crucially, settlement destinations) of all the nationalities in the world are measured, only to reveal the reality that the q...
In der Titelgeschichte dieser Sammlung flieht Kirstin Tammen nach Italien, weil sie es nicht mehr erträgt, zu Hause in Deutschland jeden Tag mit neuen Tragödien konfrontiert zu sein. Doch auch in dem Ferienhaus ihrer Kindheit gelingt es ihr nicht, die brutalen Folgen des fortschreitenden Klimawandels zu ignorieren – und die nächste Katastrophe kündigt sich schon an. »Jonas und der Held Terranovas« überträgt die Motive der biblischen Geschichte des Propheten Jona auf eine ferne Koloniewelt. Über die Frage, wie die kleine Gemeinschaft ihre internen Konflikte um das Verbot des Reisanbaus lösen soll, gerät der allseits verehrte »Captain« mit den Autoritäten seiner Welt in Streit....
Hoy día los límites del trinomio del Estado-nación (territorio-población-sistema de derechos) se ven difuminados por los diversos procesos de migración y la expansión de un incipiente sistema internacional de derechos humanos. Este libro aborda uno de dichos procesos: las crecientes prácticas de ciudadanía o nacionalidad múltiple desde la perspectiva de la migración, enfocándose en la experiencia de latinoamericamos con pasaportes europeos o de Estados Unidos.
Voltage source converters (VSCs), among other power converters, play a crucial role in supplying power to both local loads and the grid at the PCC. During stand-alone operation, VSCs ensure stable power for loads by regulating the output voltage. In grid-connected mode, the regulation shifts to controlling output current, such as converter side current (CSC) or grid side current (GSC), to inject sinusoidal current into the electrical grid. The nonlinear characteristics of the loads connected to the power converters result in significantly distorted output voltages. This capability is crucial for applications such as uninterruptible power supply (UPS), emphasizing the importance of precise ou...
