At home in the world? Bharata Natyam as transnational interpreter.

This article examines dancers' practice, in Bharata Natyam, of providing a verbal translation of dance pieces before performing them. It critiques the demand for such discursive interpretation through a discussion of textual orientalism. This is the only article in print to raise such a discussion. It proceeds to consider choreographic strategies as alternative modes of translation. This essay, therefore, is one of the few in the Bharata Natyam field that looks at particular, contemporary works of choreography in detail and as a method of discussing the politics of representation within the form

High yield hydrogen from the pyrolysis-catalytic gasification of waste tyres with a nickel/dolomite catalyst

Nickel/dolomite catalysts have been prepared and investigated for their suitability for the production of hydrogen from the two-stage pyrolysis-gasification of waste tyres. Experiments were conducted at a pyrolysis temperature of 500 °C and gasification temperature was kept constant at 800 °C with a catalyst/waste tyres ratio of 0.5. Fresh and reacted catalysts were characterised using a variety of methods, including, BET, X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM)-energy dispersive X-ray spectrometry (EDXS). The results indicated that the gas yield was significantly increased from 30.3 to 49.1 wt.% and the potential H production was doubled with the introduction of 5%Ni into the calcined dolomite catalyst. The results show also a further increase in the gas yield and the potential H production with increasing Ni loading from 5 to 20 wt.%. The coke deposited on the catalyst surface was 3.1, 0.9, 2.8 and 3.7 wt.%, when the Ni loading was 0, 5, 10 and 20 wt.% for the calcined dolomite catalyst, respectively. The results showed that the calcined Ni dolomite catalysts became deactivated by filamentous carbons
