The crystal habit of stishovite changes with the temperature of crystallization at a pressure of about 120 kb. Below 600 degrees C it is bipyramidal; between 600 degrees and 900 degrees C it is granular; and above 900 degrees C it is acicular. This temperature dependence of the crystal habit of stishovite may constitute a highpressure geological thermometer which could indicate limiting values ...

Results of a comparison study of the tracking accuracy of two commercially available wide-range position tracking systems suitable for CAVEs are presented. An experiment was conducted with Flock of Birds and IS-900 tracking systems installed in the same CAVE environment to compare their accuracy. Another experiment was performed with a newly deployed IS-900 to investigate the impact of differen...

Barium hexafemte doped with iridium was synthesized by two methods: the citrate gel and the polyacrylamide gel methods. The nature of phases obtained and the specific surface area were determined after heat treatments in air at 700°C, 900°C and in air containing 10% humidity at 1200°C. The catalytic activity in the combustion of methane was measured after heat treatment at 900°C. These hexaferr...

Abstract This article explains why Æthelflaed, ruler of Mercia, mattered to writers history in twelfth-century England. It argues that these evaluated and compared rulers based not on sex or bloodline, but the quality a ruler’s achievements relative set scale challenges faced. They thought Æthelflaed remarkable because her triumphs for Mercia distinguished from other rulers. The shows new under...

Abstract This study examines all the surviving examples of short prose pieces written in praise embroidery depicting Buddhist objects worship between circa 700 and 900. The process whereby they were transmitted to present is traced wherever possible, main themes are indicated by means identification recurrent vocabulary items. Typically, embroideries described said have been created women for p...

Whilst poor response to clopidogrel is associated with adverse outcomes uncertainty exists as to how (a) response should be assessed and (b) poor responders managed. We utilised VerifyNow P2Y12 and short Thrombelastography (TEG) to assess 900 mg doses in (i) initial poor responders to 600 mg and (ii) in a randomised comparison with 600 mg. Blood was taken before and six hours post clopidogrel i...
