Cloning of new Rhodococcus extradiol dioxygenase genes and study of their distribution in different Rhodococcus strains

Four extradiol dioxygenase genes which encode enzymes active against catechol and substituted catechols were cloned from two different Rhodococcus strains, and their nucleotide sequences were determined. A catechol 2,3-dioxygenase gene (edoC) was shown to be identical to the previously described ipbC gene from the isopropylbenzene operon of Rhodococcus erythropolis. Amino acid sequences deduced from the three other genes (edoA, edoB and edoD) were shown to have various degrees of homology to different extradiol dioxygenases, The EdoA and EdoB dioxygenases were classified as belonging to the third family of type I oxygenases and represented two new subfamilies, whereas the EdoD dioxygenase was a type II enzyme. Analysis of six Rhodococcus strains revealed a wide distribution of the above dioxygenase genes. Rhodococcus sp. I1 was shown to harbour all four of the analysed dioxygenase genes. Nucleotide sequences homologous to the edoB gene were present in all of the strains, including R. erythropolis NCIMB 13065, which did not utilize any of the aromatic compounds analysed. The latter finding points to the existence of a silent pathway(s) for degradation of aromatic compounds in this Rhodococcus strain.

Compost city: underground music, collapsoscapes and urban regeneration

This paper looks at the recent history of Hulme, Manchester, which during the 1980s was home to many of the most successful bands of the post-punk era. This flourishing of underground music was not planned, however. It emerged, through a complex network of urban forces, some physical, some social. The paper develops the concept of the ‘compost city’ a laissez-faire approach to the management of urban culture, which is oppositional to the current vogue for more hands-on cultural industries management.

Dis)Harmony in Illyria: Music, Order, and Time in Twelfth Night:Music, Order, and Time in Twelfth Night

This paper considers the integral aspect of music as performed in Shakespeare's Twelfth Night. It posits that music is that which orders and structures time in its interplay throughout the play.

Rape Myths, Law, and Feminist Research: 'Myths About Myths?'

In an article recently published in the Oxford Journal of Legal Studies, the legal scholar Helen Reece argues that the prevalence and effects of rape myths have been overstated and the designation of certain beliefs and attitudes as myths is simply wrong. Feminist researchers, she argues, are engaged 'in a process of creating myths about myths' in a way that serves to close down and limit productive debate in this 'vexed' area. In this article we argue that Reece's analysis is methodologically flawed, crudely reductionist and rhetorically unyielding. We locate Reece's analysis within the wider theoretical field to show how her failure to engage with feminist literature on rape other than in the narrowest, most exclusionary terms, yields an approach which impedes rather than advances public understanding and panders to a kind of simplistic thinking which cannot begin to grapple with the complexity of the phenomenon that is rape. We conclude by emphasizing the continuing commitment of feminist researchers carefully to theorizing and (re)mapping the fraught field of progressive legal strategizing in order to identify and counter the kinds of risks and shortcomings of political activism with which Reece is rightly concerned.

Experimental Reconstruction of Work Distribution and Study of Fluctuation Relations in a Closed Quantum System

We report the experimental reconstruction of the nonequilibrium work probability distribution in a closed quantum system, and the study of the corresponding quantum fluctuation relations. The experiment uses a liquid-state nuclear magnetic resonance platform that offers full control on the preparation and dynamics of the system. Our endeavors enable the characterization of the out-of-equilibrium dynamics of a quantum spin from a finite-time thermodynamics viewpoint.
