X-ray diffraction analysis of cohenite from iron meteorites

X-ray diffraction investigation of cohenite from Canyon Diablo meteorites and Odessa shock standards to determine shock-induced alterations in crystal characte

Trace elements in Antarctic meteorites: Weathering and genetic information

Antarctic meteorite discoveries have created great scientific interest due to the large number of specimens recovered (approximately 7000) and because included are representatives of hitherto rare or unknown types. Antarctic meteorites are abundant because they have fallen over long periods and were preserved, transported, and concentrated by the ice sheets. The weathering effects on the Antarctic meteorites are described. Weathering effects of trace element contents of H5 chondrites were studied in detail. The results are examined. The properties of Antarctic finds and non-Antarctic falls are discussed

On volatile element trends in gas-rich meteorites

Ten volatile elements (and non-volatile Co) in co-existing light and dark portions of 5 gas-rich chondrites were studied. Patterns of distinct but non-uniform enrichment by dark admixing material are revealed. The dark admixing material is enriched in Cs; Bi and Tl covary in it. It is compositionally unique from known types of primitive materials and is apparently not derived by secondary processes from such materials

Workshop on Antarctic Glaciology and Meteorites

The state of knowledge of meteorites and glaciology is summarized, and directions for research are suggested

Studies on the Processing Methods for Extraterrestrial Materials

The literature was surveyed for high temperature mass spectrometric research on single oxides, complex oxides, and minerals in an effort to develop a means of separating elements and compounds from lunar and other extraterrestrial materials. A data acquisition system for determining vaporization rates as a function of time and temperature and software for the IEEE-488 Apple-ORTEC interface are discussed. Experimental design information from a 1000 C furnace were used with heat transfer calculations to develop the basic design for a 1600 C furnace. A controller was built for the higher temperature furnace and drawings are being made for the furnace

Brazil’s Maritime Claim: A Threat to UNCLOS?

On September 3, 2010, Brazil unilaterally expanded the offshore area where it claims jurisdiction. In an apparent effort to increase control over the exploration and exploitation of natural resources, Brazil outwardly snubbed the international laws that dictate the limits of offshore control. Less than two weeks later, the rising South American power signed a memorandum of understanding with Britain for the future purchase of eleven warships, an initiative largely seen by military analysts as a protective measure to secure the vast natural resources within its newly enlarged territory. As a signatory to the United Nations Convention on the Law of the Sea (UNCLOS), Brazil’s actions have wide ideological and practical implications

The Globality of Islam: Sharia as a Nigerian 'Self-Determination' Movement

This paper was produced as part of a project at the University of California, Santa Cruz titled Globalization, State Capacity and Islamic Movements. The objective of this paper to assess how globalization and Islam impact the capacity of national states to manage Muslim demands for self-determination expressed either as a call for establishing an Islamic state, an alternative Islamic project or greater regional autonomy. After discussing our general arguments, we turn to an analysis of the Sharia movement for self determination in twelve states located in northern Nigeria, a movement that challenged national identities, provoked inter-communal conflict and threatened the existence of the Nigerian federation.
