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

Formación en cirugía de cataratas en España: análisis de resultados de una encuesta del European Board of Ophthalmology en una cohorte española

Corresponding author.: [email protected] audienceINTRODUCTION: A survey conducted by the European Board of Ophthalmology (EBO) revealed significant differences in the surgical training of the ophthalmology residents in Europe, including a disparity between the sexes and a variation in the experience on cataract surgery (CC) between them. This study is about the Spanish sub-cohort of the survey, and its objective is to present and analyse the peculiarities of ophthalmology training in Spain within the European context, as well as discussing ways to harmonise and improve that training throughout the EU. METHODS: We analyse data of the Spanish participants in the EBO exams, defining subgroups by the Autonomous Communities existing in Spain. RESULTS: 93 of 135 requested participants (68.9%) responded. A 60.2% passed the EBO exam between 2021-2022, being mostly women (65.59%) aged 31 years old on average. The 91.4% were right-handed, coming from 13 of the 17 Spanish autonomous communities, although mostly from the Community of Valencia, Madrid and Catalonia. Respectively, 16.1%, 3.2% and 8.7% of the respondents said they have completed 10 or more training sessions on animal eyes, synthetic eyes and through the virtual reality simulator. This training was correlated with greater self-confidence in the management of a posterior capsular tear during surgery (p .025). All respondents manifested to have already performed stages of the CC. The average number of operations reported was 181.6 with regional disparities. A significant difference is observed between the sexes against women (-28.3%, p 0.03). DISCUSSION: Ophthalmologists in Spain, much more than other European countries, have greater opportunities for surgical training, with surgical procedures during the residency, that nearly triples those made by the others. Spanish women refer, like their European colleagues, to be in disadvantage in learning opportunities about cataract surgery. The Simulation Based Medical Education (SBME) allows to respond to the training deficit and complements the training on the patient. Although we demonstrate a significant correlation between the number of procedures carried out and self-confidence to operate simple cases, the SBME would be a complementary tool in self-confidence in front of a complication like capsular rupture. CONCLUSION: Spain massively adopts the model named by us "surgery for all", despite the underrepresentation of women in this area, emphasising a need for cultural change that the SBME could facilitate

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
