Low-dimensional Nitride Semiconductors
Optoelectronics and electronics of the years to come are likely to change dramatically. Most of the outdoor lighting systems will be replaced by light-emitting diodes that operate in the whole visible part of the electromagnatic spectrum. Transistors operating at high frequency and with high power are under development and likely to hit the market very rapidly. Compact solid-state lasers that operate in the near-ultraviolet range are going to be utilized for such widely used applications as read-write tasks in printer and CD drives. Ultraviolet detectors will be used at a wide scale for many application, ranging from flame detectors to medical instruments. This book concerns itself with the questions why nitride semiconductors are so promising over such a wide range of applications, what the current issues are in the research laboratories, and what the prospects of new electronic devices are in the dawn of the twenty-first century.
The Routledge Handbook of Henri Lefebvre, The City and Urban Society
The Routledge Handbook of Henri Lefebvre,The City and Urban Society is the first edited book to focus on Lefebvre's urban theories and ideas from a global perspective, making use of recent theoretical and empirical developments, with contributions from eminent as well as emergent global scholars. The book provides international comparison of Lefebvrian research and theoretical conjecture and aims; to engage with and critique Lefebvre's ideas in the context of contemporary urban, social and environmental upheavals; to use Lefebvre's spatial triad as a research tool as well as a point of departure for the adoption of ideas such as differential space; to reassess Lefebvre's ideas in relation to...
Physics of Wurtzite Nitrides and Oxides
This book gives a survey of the current state of the art of a special class of nitrides semiconductors, Wurtzite Nitride and Oxide Semiconductors. It includes properties, growth and applications. Research in the area of nitrides semiconductors is still booming although some basic materials sciences issues were solved already about 20 years ago. With the advent of modern technologies and the successful growth of nitride substrates, these materials currently experience a second birth. Advanced new applications like light-emitters, including UV operating LEDs, normally on and normally off high frequency operating transistors are expected. With progress in clean room technology, advanced photonic and quantum optic applications are envisioned in a close future. This area of research is fascinating for researchers and students in materials science, electrical engineering, chemistry, electronics, physics and biophysics. This book aims to be the ad-hoc instrument to this active field of research.
Henri Lefebvre
Philosopher, sociologist and urban theorist, Henri Lefebvre is one of the great social theorists of the twentieth century. This accessible and innovative introduction to the work of Lefebvre combines biography and theory in a critical assessment of the dynamics of Lefebvre's character, thought, and times. Exploring key Lefebvrian concepts, Andy Merrifield demonstrates the evolution of Lefebvre's philosophy, while stressing the way his long and adventurous life of ideas and political engagement live on as an enduring and inspiring interrelated whole.
The Great Ordovician Biodiversification Event: Insights from the Tafilalt Biota, Morocco
Special Publication 485 About 40 million years after the Cambrian Explosion, the Great Ordovician Biodiversification Event (GOBE) represents a second and dramatic burst in marine biodiversity, with major changes in the structure of ecosystems and the progressive replacement of the distinctive Cambrian Evolutionary Fauna by the Paleozoic Evolutionary Fauna. However, the GOBE is not a single, worldwide, short-term event, but rather the complex sum of successive diversifications occurring in distinct taxonomic groups, trophic guilds and regions. This book focuses on the Late Ordovician Tafilalt Biota, Anti-Atlas Morocco, which provides a snapshot of the GOBE in high-latitude regions of the Southern Hemisphere. A series of contributions explore different aspects of the Tafilalt Biota, including its geological setting, the international fossil trade in this area and a series of detailed systematic contributions describing many new taxa of marine invertebrates. This volume represents a significant contribution to the understanding of the Tafilalt Biota and its significance to the GOBE.
Henri Lefebvre's Critical Theory of Space
Henri Lefebvre's Critical Theory of Space offers a rigorous analysis and revival of Lefebvre’s works and the context in which he produced them. Biagi traces the historical-critical time-frame of Lefebvre's intellectual investigations, bringing to light a theoretical constellation in which historical methods intersect with philosophical and sociological issues: from Marxist political philosophy to the birth of urban sociology; from rural studies to urban and everyday life studies in the context of capitalism. Examining Lefebvre’s extended investigations into the urban sphere as well as highlighting his goal of developing a “general political theory of space” and of innovating Marxist thought, and clarifying the various (more or less accurate) meanings attributed to Lefebvre's concept of the “right to the city” (analysed in the context of the French and international sociological and philosophical-political debate), Henri Lefebvre's Critical Theory of Space ultimately brings the contours of Lefebvre’s innovative perspective—itself developed at the end of the “short twentieth century”—back into view in all its richness and complexity.
Creolization and Contact
This volume contains revised and extended versions of a selection of the papers presented at The Amsterdam Workshop on Language Contact and Creolization. These studies apply the concept of relexification to creoles as well as other contact languages; highlight the relevance of strategies of second language learning for theories of pidgin/creole genesis; critically discuss the notions levelling (koine formation) and convergence; the relation between types of contact situations and processes of crosslinguistic influence; as well as the linguistic consequences of the social structure of the plantation system. In addition to discussing English-, French-, and Dutch-related creoles, the papers cover a wide range of contact languages spoken throughout Africa, Asia, and Europe. The breadth and coverage makes this an indispensable title for research in the field of contact linguistics.
