Résultats des études menées en Angleterre: détermination de la posologie optimale

  • Description: Les auteurs ont etudie la biodisponibilite et I'activite de formules experimentales et commercialisees de dermocortico'ides en utilisant les essais de vasoconstriction avec et sans occlusion (1, 2, 6, 7, 8, 9). L'application unique de six heures avec lectures multiples a ete largement utilisee dans ce travail et la methodologie en a ete decrite en detail ailleurs (4). Sur la base de ce travail. on a pratique des applications repetees de dermocortico'ides commercialises au Royaume- Uni. en utilisant Ie test du blanchiment de la peau sans occlusion, de maniere a reproduire au plus pres la situation realisee en clinique (3). Ce travail a montre que I'application de cortico'ides trois fois par jour pendant cinq jours aboutissait a une tachyphylaxie considerable de la reponse du blanchiment quelque soit I'activite therapeutique de la formule utilisee. Au bout de deux jours de repos, on a assiste a une recuperation considerable, mais a nouveau une tachyphylaxie aigue s'est installee a la suite d'une nouvelle application triquotidienne.

Sampling in the evaluation of ore deposits

  • Authors: Grant, D E C S

  • Subjects: Ore deposits , Mine valuation , Ores -- Sampling and estimation
  • Language: English
  • Type: Thesis , Masters , MSc
  • Identifier: vital:5008 , http://hdl.handle.net/10962/d1005912 , Ore deposits , Mine valuation , Ores -- Sampling and estimation
  • Description: Sampling is an error generating process and these errors should be reduced to a minimum if an accurate ore reserve estimation is to be made from the sample values. Error in sampling can arise from the sampling procedure as well as where and how each sample is taken from the deposit . Sampling procedure involves sample collection, sample reduction and analysis, and the error from each of these three stages has an equal influence on the total error of the process. Error due to sampling procedure should be identified and eliminated at an early stage in the evaluation programme. An ore deposit should be subdivided into sampling strata along geological boundaries, and once these boundaries have been established they should be adhered to for the evaluation programme. The sampling of each stratum depends on the small-scale structures in which the grade is distributed, and this distribution in relation to sample size controls sample variance, sample bias and the volume of influence of each sample. Cluster sampling can be used where an impractically large sample is necessary to reduce sample variance or increase the volume of influence of samples. Sample bias can be reduced by composing a large number of small samples . Sampling patterns should be designed with reference to the volumes of influence of samples, and in favourable geology, geostatistical or statistical techniques can be used to predict the precision of an ore reserve estimation 1n terms of the number of samples taken. Different are deposits have different sampling characteristics and problems which can be directly related to the geology of the mineralization. If geology is disregarded when sampling an are deposit, an evaluation programme cannot claim to give an accurate estimate of the ore reserves .

Separation and characterisation of chromium (III) carboxylate solutions

- Bryson, Michael Andrew Walker

  • Authors: Bryson, Michael Andrew Walker
  • Date: 1981
  • Subjects: Chromium
  • Language: English
  • Type: Thesis , Masters , MSc
  • Identifier: vital:4416 , http://hdl.handle.net/10962/d1006847
  • Description: From Summary: The complexes present in chromium(III) carboxylate solutions (acetate or formate) were separated using ion exchange chromatography, electrophoresis and gel filtration. Eight cationic species and one non-ionic species with charges from 0 to +3 and nuclearities ranging from mononuclear to quadranuclear were isolated from chromium(III) acetate solutions. Six cationic species with charges from +1 to +3 and nuclearities ranging from mononuclear to trinuclear were isolated from chromium(III) formate solutions. The empirical formulae for these complexes were determined by analytical methods. Infra- red spectroscopy was used to distinguish between monodentate and bidentate bridged carboxylate ligands. An immediate change in the visible spectrum of a complex on its acidification was used as evidence that a terminal hydroxo group was present.
