S'orienter et élaborer un projet au sein d'un système hiérarchisé, une injonctoin paradoxale ? L'exemple du choix de la série et de l'enseignement de…
1997
The French "lycée" (higher secondary school), pupils are faced with successive subjects choices, and with the choice of Baccalauréat's speciality. This paper investigates from empirical data how these choices are progressively generated, along time and under which academic and social mechanisms. Those academic subjects choices prove to be influenced less by educational factors than by the concern to optimize one's schooling career. As long as the different routes are perceived as a hierarchy, and if concern for distinction and utilitarism are prevailing, the relevance of the notion of project has to be questionned.
Determination of cholesterol in human milk: an alternative to chromatographic methods
2015
Introduction: human milk (HM) is considered the best option for feeding healthy infants. Cholesterol (CHOL) is important for proper development of the nervous system, and for hormone and vitamin synthesis in growing infants. Breastfeeding and dietary CHOL intake during infancy have been suggested to affect blood lipid levels and the risk of cardiovascular disease in adulthood. Gas chromatography is the technique most widely used to determine CHOL in HM. Chromatographic methods are specific for the determination of CHOL and other sterols present in HM, but are extremely time consuming, and the costs and equipment requirements mean that they are not accessible to all laboratories. Aim: the pr…
Die quantitative Bestimmung der p-Oxyphenylbrenztraubens�ure im Harn
1950
Es wird ein Verfahren zur quantitativen Bestimmung der p-Oxyphenylbrenztraubensaure im Harn beschrieben, das auf der Reduktion der p-Oxyphenylbrenztraubensaure zur p-Oxyphenylmilchsaure beruht. Die Methode gestattet den spezifischen Nachweis der im Harn ausgeschiedenen p-Oxyphenylbrenztraubensaure und ist geeignet, die Leberfunktionsprobe nachFelix undTeske wesentlich zu vereinfachen.
Production, isolation and characterization of radiochemically pure 163Ho samples for the ECHo-project
2018
Abstract Several experiments on the study of the electron neutrino mass are based on high-statistics measurements of the energy spectrum following electron capture of the radionuclide 163Ho. They rely on the availability of large, radiochemically pure samples of 163Ho. Here, we describe the production, separation, characterization, and sample production within the Electron Capture in Holmium-163 (ECHo) project. 163Ho has been produced by thermal neutron activation of enriched, prepurified 162Er targets in the high flux reactor of the Institut Laue-Langevin, Grenoble, France, in irradiations lasting up to 54 days. Irradiated targets were chemically processed by means of extraction chromatogr…

Extraktionschromatographische trennung der freien uroporphyrinisomere i und iii und deren simultane quantitative bestimmung
1968
Abstract Separation and simultaneous quantitative determination of the free uroporphyrin isomers I and III by means of extraction chromatography Separation and quantitative determination of the uroporphyrin isomers I and III in the acid from can be performed simultaneously in the partition system tri-n-butylphosphate/I N hydrochloric acid using columns with a large number of theoretical plates (N) = 300-450). The eluent is passed through a flow cuvette and the transmission is recorded continuously. The transmission peaks of the isomers are digitized and transformed into extinction values. By integrating the extinction peaks, the amount of the uroporphyrins can be evaluated from the correspo…
Hard cap espresso extraction-stir bar preconcentration of polychlorinated biphenyls in soil and sediments.
2017
Abstract A Nespresso © hard cap espresso machine has been employed for the quantitative extraction of polychlorinated biphenyls (PCBs) from sediments and soils. Sample extraction was performed from five grams of sample in less than 40 s, with 200 mL ethanol 40% (v/v) in water and PCBs were concentrated using stir bar sorptive extraction (SBSE) and determined by thermal desorption-gas chromatography-tandem mass spectrometry (TD-GC-MS-MS). Eleven PCB congeners (28, 52, 77, 80, 81, 101, 118, 138, 153,169, and 180) were determined in soils and sediments with limits of quantification in the 0.03–0.08 ng g −1 range. Extraction efficiency was established by the analysis of soil samples spiked with…
El derecho de autonomia del paciente menor: Virtualidad de la mediacion en conflictos sanitarios con menores
2017
La Ley 41/2002, de 14 de noviembre reconoce el derecho a la autonomía del paciente en el ámbito sanitario, configurado como un derecho subjetivo en el marco de los derechos de la personalidad. Recientemente, las Leyes Orgánica 8/2015, de 22 de julio y Ley 26/2015 de 28 de julio han introducido importantes reformas en la consideración de la madurez de los menores para decidir determinados actuaciones que afectan a su persona, confiriendo a sus progenitores la facultad de consentir intervenciones sanitarias que puedan suponer grave riesgo para su vida o salud. Regulación ésta que plantea ciertos interrogantes a la hora de ofrecer soluciones a ciertos conflictos familiares y sanitarios que se …
VIII: Statistik in klinischen Publikationen: Checklisten für Autoren
2003
The "Material and Methods" section of clinical research papers should reference major aspects concerning statistical planning and evaluation of the study design and the resulting clinical data. Particular focus is laid on the listing of methods for description and significance evaluation of the trial data, as well as on design-associated study determinants (randomisation and masking strategy, response rate evaluation, primary endpoints, power and sample size determination, multiple testing, software and methods for statistical analysis). Suggestions for the minimum content to be mentioned in a trial publication are listed in author check lists and are illustrated by means of the study synop…
