Deploying a spatial approach towards children’s everyday life in interwar Hong Kong, this book considers the context-specific development of five transnational movements: the garden city movement; imperial hygiene movement; nationalist sentiments; the Young Women's Christian Association; and the Girl Guide. Locating these transnational cultural movements in four layers of context, from the most immediate to the most global, including the context of Hong Kong, Republican China, the British empire, and global influences, this book shows Hong Kong as a distinctive colonial domain where the imperatives around race, gender and class produced new products of empire where the child, the garden, the school and sport turned out to be the main dynamics in play in the interwar period.
Disasters are characterized by severe disruptions of the society’s functionality and adverse impacts on humans, the environment, and economy that cannot be coped with by society using its own resources. This work presents a decision support method that identifies appropriate measures for protecting the public in the course of a nuclear accident. The method particularly considers the issue of uncertainty in decision-making as well as the structured integration of experience and expert knowledge.
This book examines the contested re-readings of “Korea” in early Chinese historical records and their influence on the formation of Korean-ness in later periods. The earliest written records on “Koreans” are found in Chinese documents produced during the Han dynasty, from the third century BCE to the third century CE. Since then, these early Chinese records have been used as primary sources for writing early Korean history in Korea, China, and Japan. This study analyzes the various reinterpretations and utilizations of these early records that became more diverse by the late nineteenth century, when the reconstruction of ancient history became a crucial part of the formation of Korean national consciousness. Korea’s modern historiography was complicated by a thirty-five year colonial experience (1910–1945) under Japan. During this period, Japanese colonial scholars attempted to depict Korean history as stagnant, heteronymous, and replete with factional strife, while Korean nationalist historians strove to construct an indigenous Korean nation in order to mobilize Koreans’ national consciousness and recover political sovereignty. While focused on Korea and Northeast Asia, the links between historiography and political ideology investigated in this study are pertinent to historians in general.
Every day in our life is larded with a huge number of chemical reactions on surfaces. Some reactions occur immediately, for others an activation energy has to be supplied. Thus it happens that though a reaction should thermodynamically run off, it is kinetically hindered. Meaning the partners react only to the thermodynamically more stable product state within a mentionable time if the activation energy of the reaction is supplied. With the help of catalysts the activation energy of a reaction can be lowered. Such catalytic processes on surfaces are widely used in industry. Around 90% of chemicals are produced via a heterogeneously catalyzed process where a reaction occurs on the surface of a catalyst. However, why is it generally possible that such reactions run off with the help of heterogeneous catalysis, meaning with lower activation energy than without presence of a catalyst? What happens with the energy which is released during a reaction of gas particles on surfaces? How is this energy released, when some part of the energy is transferred to the reactant and some to the chemically active surface? Which physical mechanisms play a key role in the energy transfer? These questions are summarized in the concept of the energy dissipation. To observe this energy dissipation phenomenon, we use a new method, the chemoelectronics. With this method we try to detect the released energy, induced by reactions on surfaces, via thin-layered electronic device elements. An aim of this work is to build up very sensitive chemoelectronic sensors to measure electronic excitations released during such simple reactions of molecules as adsorption and desorption and more complicated reactions as the water formation reaction. Therefore a new line of chemoelectronic sensors is developed and characterized in terms of internal photoemission and stability. Meaning the previously used aluminum (Al-AlOx-Ag) and tantalum based (Ta-TaOx-Au) metal-insulator-metal sensors (MIM) are tested and new titanium based (Ti-TiOx-Au) MIMs are developed. Additionally silicon based stepped-metal-insulator-semiconductor sensors (stepped-MIS, Si-SiOx-Au, Si-SiOx-Pt) are set up and characterized. For the characterization of the chemoelectronic sensors the process of internal photoemission is used. Both, chemical- and photoexcitation release hot charge carriers (electrons and holes). Due to the existence of excited carriers in the sensor, a current can be measured without applying a bias voltage. It will be shown that the chemo- and the photosensitivity are strongly related to each other. As a first experiment for the chemical selectivity of the detectors, a stream of excited hydrogen molecules and hydrogen atoms is used. The excitation and radical formation is produced by the interaction of ground state molecules with a hot tungsten surface according to the pioneering experiments of Irving Langmuir. Additionally, excited oxygen beams are studied in this work.
Drug products are complex mixtures of drugs and excipients and, as such, their chemical and physical stability kinetics are complex. This book discusses the stability of these dosage forms with preformulation studies through to the studies on the final products. The book is intended for graduate students, researchers and professionals in the field of Pharmaceutics and Pharmaceutical Chemistry.
