One British Thing: Clay Pipes

Abstract

The clay tobacco pipe is a “British thing” distinct to its time, but that is a partial provenance. Although many thousands have been unearthed in Britain or described in British archival records, the pipe is also evidence of early globalized trade, imperial ventures, and material translation across cultures. Its Britishness is contingent. This small relic accompanied complex enterprises where a new-style masculinity arose, new racial categories were framed, and a new sociability took root.

Dewar valence isomers, the third type of environmentally relevant DNA photoproducts induced by solar radiation

“…13,18 A quantum yield of 2% was determined for the isomerisation of TpT and TpdC 64PPs. 19 A higher efficiency of 8% was recently reported for the photoisomerisation using time-resolved spectroscopy. 12 However, the quantum yield of conversion of 64PP into Dewar is reduced by a factor of 4 in double-stranded DNA due to the presence of the adjacent bases.…”
