Saturated ternary systems. IV Solubility isotherms of organic compounds in water-ethanol mixtures

The constants in solubility isotherms were determined acoord- ing to E. I. Ahumov1 for the systems water-ethanol-organic substance, in which organic substances were: isobutyl bromide, benzaldehyde, bromotoluene, benzyl ethylether, ipropylbromide, iso-amylbromide, iso-amylether, a-xylene, isobutylalcohol, diethyl ketone, phenetole, m-xylene, chloroform, p -xylene, nitrobenzene, ethyl acetate, benzyl acetate, camphor, mesitylene, pinene, hexane, p-nitrotoluene, toluene, cyclohexane, ethyl bromide, o-toluidine, ethyl butyra.te, ethyl propionate, methyl-aniline, benzene, xylene and bromobenzene

Deep into the Night the City Calls as the Blacks Come Home to Roost

In Jean Genet’s self-designated clown show, The Blacks, black actors in white masks play out the proceedings of a tribunal organized to pass judgment on the black perpetrator of the rape of a white woman. There are continuously oblique references to a scenario off-stage where a revolt by blacks which may be under way is side-tracked by having to deal with a traitor among them. In ‘reality’, the crime never took place, and the necessary detour of having to dispose of a traitor becomes the haunting mechanism that identifies the claustrophobic, circular game of reflections and inversions that keep black and white locked into a continuous reiteration of the normative grammars of power. The trajectories of desire, anger, freedom and subjection are held together by the very dissimulations, performances, role-playing, trade-offs and revolutions that take place. Clearly it is the way race is spatialized, and the way that the arbitrary elaboration of identities, so easily interchangeable among themselves, is put to work that holds together specific contexts of operation

Performance measures for small-bowel endoscopy: a European Society of Gastrointestinal Endoscopy (ESGE) Quality Improvement Initiative

The European Society of Gastrointestinal Endoscopy (ESGE) together with the United European Gastroenterology (UEG) recently developed a short list of performance measures for small-bowel endoscopy (i.e. small-bowel capsule endoscopy and device-assisted enteroscopy) with the final goal of providing endoscopy services across Europe with a tool for quality improvement. Six key performance measures for both small-bowel capsule endoscopy and for device-assisted enteroscopy were selected for inclusion, with the intention being that practice at both a service and endoscopist level should be evaluated against them. Other performance measures were considered to be less relevant, based on an assessment of their overall importance, scientific acceptability, and feasibility. Unlike lower and upper gastrointestinal endoscopy, where performance measures had already been identified, this is the first time that small-bowel endoscopy quality measures have been proposed
