The new mobilities paradigm has yet to have the same impact on archaeology as it has in other disciplines in the social sciences - on geography, sociology and anthropology in particular - yet mobility is fundamental to archaeology: all people move. Moving away from archaeology’s traditional focus upon place or location, this volume treats mobility as a central theme in archaeology. The chapters are wide-ranging and methodological as well as theoretical, focusing on the flows of people, ideas, objects and information in the past; they also focus on archaeology’s distinctiveness. Drawing on a wealth of archaeological evidence for movement, from paths, monuments, rock art and boats, to skeletal and DNA evidence, Past Mobilities presents research from a range of examples from around the world to explore the relationship between archaeology and movement, thus adding an archaeological voice to the broader mobilities discussion. As such, it will be of interest not only to archaeologists and historians, but also to sociologists, geographers and anthropologists.

This edited volume adds to the literature on Myanmar and its borders by drawing attention to the significance of geography, history, politics and society in the construction of the border regions and the country. First, it alerts us to the fact that the border regions are situated in the mountainous and maritime domains of the country, highlighting the commonalities that arise from shared geography. Second, the book foregrounds socio-spatio practices -- economic, intimate, spiritual, virtual -- of border and boundary-making in their local context. This demonstrates how state-defined notions of territory, borders and identity are enacted or challenged. Third, despite sharing common features, Myanmar's borderscapes also possess unique configurations of ethnic, political and economic attributes, producing social formations and figured worlds that are more cohesive or militant in some border areas than in others. Understanding and comparing these social practices and their corresponding life-worlds allows us to re-examine the connections from the borderlands back to the hinterland and to consider the value of border and boundary studies in problematizing and conceptualizing recent changes in Myanmar. "This ambitious project combines sophisticated theorization of boundary-making as a form of social practice and empirical studies of Myanmar's heterogeneous borderlands, both land and sea. Seeing the country from its edges opens up a provocative and altogether novel vision of the contestations joining diverse peripheries and centre. This volume brings together the leading scholars of the country in a collection that is a must-have for anyone interested in contemporary Myanmar, border studies, and Southeast Asia." -- Itty Abraham, Head, Department of Southeast Asian Studies, National University of Singapore (NUS) "This is the first book to attempt to bring together such a diverse range of Myanmar's land and maritime border regions for comparison. In doing so, it highlights the diversity of the country's demographic, social, economic and political make-up when viewed from the margins rather than the centre. It reveals how these border regions help to constitute the nation and how they shape what modern Myanmar is today -- they also give strong indicators of what it might become. This is an essential read for anyone in the social sciences interested in borderlands, as well as those requiring a broader understanding of the challenges facing the contemporary Myanmar government as it attempts to usher in social and political cohesion following decades of conflict." -- Mandy Sadan, Reader in the History of South East Asia, School of Oriental & African Studies (SOAS)

The results of drift mobility and space-chargelimited crrent meaurements made on 20-micronthick films of amorphous Se were interpreted using the band model of a semiconducting solid with impurity or imperfection levels in the forbidden energy region between the conduction and valence bands. Drift mobilities were measured in the 220 to 300 K temperature range by determining the time of transit across the films of carriers which were photoinjected at one surface by 10 to the -8th power sec light pulses. The drift mobilities at 300 K were 0.165 sq cm/v sec for holes and 7.8 x 0.001 sq cm/v sec for electrons. The temperature dependence of hole mobility was exp( -0.14 ev/kT), and that of electrons was exp( -0.285 ev/kT). About 10 to the 19th power/cc electron traps were present in a 0.285-ev region just below the conduction band edge; about 10 to the 21st power/cc hole traps occupied a 0.14-ev portion of the gap immediately above the valence band edge. Au and Te electrodes were used to inject holes into amorphous Se, producing space-charge-limited currents at high fields. Electrical conductivities of 10 to the -14th to 10 to the -16th power/ohm/cm were obtained at low fields. (Author).

Diamond, as well as being a precious gem, is a versatile material par excellence. No other material comes anywhere near to matching its properties, which are both extreme, and also expressed in rare combinations. However, natural diamonds, and those synthesised under high sandpressure temperatures, are too expensive or small for many technological applications. These limitations can be overcome by using large-area diamond coatings; chemically bonded to inexpensive non-diamond surfaces. The consequent economic advantages provide the driving force for much diamond-related research and technology.
