Separation of a binary fatty acid

Separation of a binary fatty acid find more mixture of lauric acid and myristic acid using physical vapour deposition (PVD) on a cold quartz crystal resonator is examined. The extremely small amount of deposits can be measured with the quartz crystal resonator. The vapour phase is prepared by vaporizing a calculated composition of melt according to the vapour-liquid equilibrium (VILE).\n\nRESULTS: The composition of lauric acid in the melt and the melt temperature were utilized as operating variables in the PVD. The growth rate of

deposit increases when melt temperature and the composition of lauric acid in the melt are increased. The composition of lauric acid in the deposit is significantly lower than that of the melt of 19% lauric acid, but the composition of lauric acid in the deposit is much higher than that of the melts of 50% and 75% lauric acid.\n\nCONCLUSION: The distribution coefficient of lauric acid between solid and vapour phases can be correlated as a function of the growth rate of deposit. The possibility of separation of fatty acid mixtures by PVD is suggested click here experimentally and theoretically. (C) 2008 Society of Chemical Industry”
“Objectives: The aim of this study is to determine the risk factors for rupture of an ectopic pregnancy (EP)

to help physicians identify those women who are at greatest risk.\n\nStudy design: The study group comprised the cases of EP treated in our department from January 2003 to September 2009. The following parameters were retrospectively examined: rupture status, past history of pelvic infection or EP, use of an intrauterine device (IUD), parity and gestational age. Women with tubal rupture were compared to those without rupture. Where appropriate, univariate and multivariate analyses were used to

identify predictors of the outcome of EP.\n\nResults: Two hundred and thirty-two cases of EP were retrieved. Eighty-eight selleck kinase inhibitor of them (37.9%) were cases with ruptured EP and 144 (62.1%) were cases with unruptured EP. No significant associations existed regarding IUD use, smoking, previous ectopic pregnancy, past history of pelvic inflammatory disease (PID) or history of endometriosis. The mean gestation (in weeks) since the last menstrual period and the mean level of beta hCG were significantly higher in patients with ruptured EP compared with patients with unruptured EP (7.8 +/- 1.09 versus 6.4 +/- 1.2, p < 0.0001; and 8735.3 +/- 11317.8 IU/ml versus 4506 +/- 5673.7 IU/ml, p < 0.0001, respectively). Logistic regression analysis revealed that 6-8 weeks of amenorrhoea (OR: 3.67; 95% CI: 1.60-8.41) and > 8 weeks of amenorrhoea (OR: 46.46; 95% CI: 14.20-152.05) and also 1501-5000 IU/ml of beta hCG level (OR: 4.11; 95% CI: 1.53-11.01) and > 5000 IU/ml of beta hCG levels (OR: 4.40; 95% CI: 1.69-11.46) were the significant risk factors for tubal rupture.
