Roy Williams: representing multicultural Britain in Fallout

This article considers how Roy Williams's 2003 play, which dramatises a black-on-black killing and the flawed police investigation which follows, represents contemporary British society, particularly in relation to the vexed question of multiculturalism. Some have described "Fallout" as limited and bleak, reinforcing stereotypes of black experience and identity. By contrast, this article demonstrates that the play, through its analysis of both a conflicted police service and the societal divisions that push black youths towards criminality, draws attention to the underlying systemic causes of inner city violence and makes a constructive and valuable contribution to ongoing public debate.

Caking strength of granulated clay under frozen conditions

Transport of particulate clay occurs during some extremely cold weather conditions typically in the winter in the far North area. During the transport and temporary storage time, the clay may cake inside a rail or road wagon or in a silo, and consequently be difficult to be discharged from the containers. This paper studied caking strength of a granulated clay powder with a certain water moisture content of 18% for influences of temperature, packing stress and freezing time. The temperature tested was -5 oC, -10 oC and -20 oC. Because the clay powder may be packed at different bed depth, the study was undertaken across the packing stress range at 8.3 kPa (1 m bed depth), 25.0 kPa (3 m) and 75.0 kPa (9 m). Freezing time varied between 4 hours (transport) and 18 hours (overnight). During the tests, failure of caked materials was measured using a QTS texture analyzer and the caking strength of frozen samples was calculated. Influences on freeze caking of granular clay in storage or transport are discussed briefly. Some conclusions are made at the end of the paper,including recommendations for practical methods for mitigating these problems.
