Abstract

We provide the first assessment for a coral reef fish population of a potentially threatened endemic species from a remote and isolated oceanic island. Based on a 3-dimensional (3D) numerical field model of the reef habitat and underwater visual censuses conducted by 2 different teams in February and May 2016, we show that the 3.7 km2 of the Clipperton Atoll reefs shallower than 30 m host >50000 ind. (average density of 0.02 ind. m-2) of the endemic Clipperton angelfish Holacanthus limbaughi. Based on limited submersible observations to 150 m, the population likely extends below the 30 m depth stratum, resulting in an even larger population size and providing a potential depth refuge against expected warming ocean temperatures.

Abstract

Non-Hodgkin lymphoma (NHL), multiple myeloma and chronic lymphocytic leukemia are possibly related to environmental and/or occupational exposure. The primary objective of this study was to develop a questionnaire for screening patients with these blood disorders who might benefit from a specialized consultation for possible recognition of the disease as an occupational disease. The study included 205 subjects (male gender, 67.3%, mean age, 60 years, NHL, 78.5%). The questionnaire performed very satisfactorily in identifying the exposures most frequently retained by experts for their potential involvement in the occurrence of NHL. Its sensitivity and specificity in relation to the final expertise were 96% and 96% for trichloroethylene, 85% and 82% for benzene, 78% and 87% for solvents other than trichloroethylene and dichloromethane, 87% and 95% for pesticides, respectively. Overall, 15% of the subjects were invited to ask National Social Insurance for compensation as occupational disease. These declarations concerned exposure to pesticides (64%), solvents (trichloroethylene: 29%, benzene: 18%, other than chlorinated solvents: 18%) and sometimes multiple exposures. In conclusion, this questionnaire appears as a useful tool to identify NHL patients for a specialized consultation, in order to ask for compensation for occupational disease.

31. Étude pilote FSLPRO-DIAL : apport du capteur Freestyle Libre Pro chez des patients avec un diabète de type 2 en hémodialyse

Author

Henry, Z., Villar, E., Chauvet, C., Belloi, A., Prunescu, I., Doroszewski, F., Luyton, C., and Marchand, L.

Abstract

Le contrôle du diabète est souvent difficile à obtenir chez des patients en hémodialyse, et l’HbA1c est un marqueur de suivi moins performant dans cette population. Nous avons cherché à comparer la valeur de l’HbA1c “laboratoire” avec celle du GMI (HbA1c estimée par un capteur) chez des patients avec un diabète de type 2 (DT2) (avec ou sans traitement à l’insuline) en hémodialyse, et à analyser les nouveaux paramètres de surveillance du glucose.

33. Weibull statistics in short-term dielectric breakdown of thin polyethylene films

Abstract

A Weibull statistical analysis of breakdown voltages of thin polyethylene-insulated power cable slices is performed on large populations. Computation of confidence intervals implies that the statistically correct description is a three-parameter Weibull distribution, i.e. with a non-zero location parameter. It is shown that a data set described by a two-parameter Weibull distribution contains additional statistical dispersion factors which may or may not yield information on the insulation itself. In other words, a zero-location parameter always results from inhomogeneities in the sampling. These may be due to uncontrolled experimental parameters or to defects of various origins; but aging is also a source of dispersion of the electrical properties of dielectrics. To discriminate between the two, we proceed by comparative testing. When obtained under carefully controlled experimental conditions, the location parameter value can be considered a true quality factor of the system under test. The possible physical meaning of the so-called threshold may be envisaged once the breakdown mechanism at work under the conditions of the test is known. The statistical analysis of data collected in routine breakdown tests provides a very sensitive tool to investigate small changes in electrical insulation when performed on extensive data sets.

46. Raman study of Zn[sub 1-x]Be[sub x]Se/GaAs systems with low Be content (x≤0.20).

Abstract

We present an experimental and theoretical investigation of the Raman line shape of long-wavelength phonons with longitudinal optical (LO) symmetry from both sides of Zn[sub 1-x]Be[sub x]Se/GaAs (001) heterojunctions with special emphasis on samples with low Be content (x≤0.20). First the built-in p-type LO phonon-plasmon (LO-P) coupled mode at the near-interfacial substrate is used as a sensitive probe to investigate the interfacial quality. The corresponding hole gas is reinforced when the ZnBeSe layers are nominally p doped by nitrogen. This provides clear evidence for effective hole transfer across the junction, and thereby indicates a minimized density of interfacial defects. In the nitrogen-doped layers hole densities as high as 10[sup 17] cm[sup -3], in accordance with capacitance-voltage measurements, are directly inferred from clear weakening of the ZnSe-like LO mode due to LO-P coupling. Concerning the intrinsic properties of the alloys, we demonstrate that the asymmetric broadening of the ZnSe-like LO mode is determined by topological disorder only, and not by other possible mechanisms such as structural disorder, nonhomogeneity in the alloy composition, a distribution of tensile strain, or a Fano-type interference. This reveals a high structural quality that parallels the high interfacial quality. We also show that a spatial correlation model with Gaussian distribution applies to Zn[sub 1-x]Be[sub x]Se. Most of this study is supported by a quantitative treatment. We extend the phenomenological approach of Hon and Faust to equations of motion and polarization derived from the modified-random-element-isodisplacement model in order to achieve line shape analysis of the alloy-related LO and LO-P modes.

Abstract

Routine breakdown tests performed on large populations of laboratory-aged polyethylene insulated power cable slices and slices taken from aged cables are analyzed according to a Weibull model. The unaged reference populations are described by a three-parameter distribution, i.e. with a non-zero location parameter or threshold. On the contrary, the aged populations may be fitted by a simple two-parameter model. A tentative interpretation stating a threshold dependence on aging is proposed on the basis of previous results.
