    Les objectifs de cette thÚse consistent à identifier les morphologies adoptées par des mélanges d élastomÚres chargés en noir de carbone, à étudier l influence de l introduction de charges sur ces morphologies mais aussi de détecter la localisation de la charge dans ces mélanges. Dans une derniÚre partie, l impact de ces différentes structures sur les défauts d extrusion est abordé. Ces travaux concernent l étude des coupages caoutchouc naturel / styrene-butadiene rubber (NR / SBR) et polybutadiÚne / styrene-butadiene rubber (BR / SBR) non vulcanisés. Dans un premier temps, les morphologies adoptées par ces mélanges non chargés ont été identifiées grùce à plusieurs protocoles expérimentaux. L influence de l introduction de noir de carbone ainsi que l étude de la localisation de la charge dans ces mélanges ont constitué une seconde étape dans ces travaux. Aucune localisation préférentielle de la charge n a été détectée pour ces mélanges. Un systÚme ségrégé a donc été réalisé par la suite. Enfin, le comportement en extrusion de ces mélanges a été simulé par rhéométrie capillaire et des observations de défauts d aspect ont été faites. La ségrégation du noir de carbone ne semble pas entraßner la création de défauts d aspect, sauf dans le cas d une localisation dans la matriceThe purpose of this project is to investigate the morphology of elastomeric blends filled with carbon black, the localization of the filler in these blends and the structure impact on their processing. This work concerns uncured natural rubber / styrene-butadiene rubber (NR / SBR) blends and butadiene rubber / styrene-butadiene rubber (BR / SBR) blends. Firstly, the morphology of these blends unfilled was described by different experimental procedures over the entire composition range. Secondly, the impact of the filler on the morphology and the localization of it on the blends were studied. No preferential localization was observed in our case. Another blend with a segregation was realized. And finally, the processing of these elastomeric blends was simulated by capillary rheology to detect the formation of flow instabilities. Few melt fractures were observed, except when the filler is localized in the matrixST ETIENNE-Bib. électronique (422189901) / SudocSudocFranceF

    Engineering Hybrid Epitaxial InAsSb/Al Nanowire Materials for Stronger Topological Protection

    Get PDF
    The combination of strong spin-orbit coupling, large gg-factors, and the coupling to a superconductor can be used to create a topologically protected state in a semiconductor nanowire. Here we report on growth and characterization of hybrid epitaxial InAsSb/Al nanowires, with varying composition and crystal structure. We find the strongest spin-orbit interaction at intermediate compositions in zincblende InAs1−x_{1-x}Sbx_{x} nanowires, exceeding that of both InAs and InSb materials, confirming recent theoretical studies \cite{winkler2016topological}. We show that the epitaxial InAsSb/Al interfaces allows for a hard induced superconducting gap and 2ee transport in Coulomb charging experiments, similar to experiments on InAs/Al and InSb/Al materials, and find measurements consistent with topological phase transitions at low magnetic fields due to large effective gg-factors. Finally we present a method to grow pure wurtzite InAsSb nanowires which are predicted to exhibit even stronger spin-orbit coupling than the zincblende structure.Comment: 10 pages and 5 figure

    New Data on the Genesis and Evolution of the Primitive Magmas of Mount Cameroon: Contribution of Melt Inclusions

    Get PDF
    Mount Cameroon is a Plio-Quaternary volcanic massif, without a centralcrater, made up of more than 140 pyroclastic cones. It is one of theactive volcanoes of the Cameroon Volcanic Line. Mount Cameroon meltinclusions are found in microdroplets trapped in the early minerals (olivines)from the pyroclastic products. The analysis of these melt inclusions allowedus to find primitive liquids compared to lavas. Major elements study ofthe magmatic inclusions, trapped in the most magnesian olivines (Mg#84-86) of Mount Cameroon revealed “primitive” liquids of basanite and alkalibasalt type with variable composition compared to the much more uniformbasalts of the magmatic series of Mount Cameroon. The study of thesetrapped liquids shows that: (1) the original primitive lavas did not undergothe process of evolution by FC, but rather underwent fundamentally (orexclusively) the process of partial melting; (2) the emitted lavas, evolvedessentially by FC; (3) the variations in the trace element contents of theprimitive liquids directly reflect a variation in the rate of partial melting ofa homogeneous mantelic source. The very high La/Yb ratios of the MountCameroon melt inclusions (> 20) characterize a garnet lherzolite source.Spectra of the melt inclusions show a negative anomaly or depletion in K,Rb and Ba as those of HIMU. The “primitive” liquids and lavas of MountCameroon represent a co-genetic sequence formed by varying degrees ofpartial melting of a source considered as homogeneous

    Reproductive outcomes in male childhood cancer survivors: a linked cancer-birth registry analysis

    OBJECTIVE: Compare the risk of reproductive and infant outcomes between male childhood cancer survivors and a population-based comparison group. DESIGN: Retrospective cohort study. SETTING: 4 U.S. regions. PARTICIPANTS: Cancer registries identified males <20 years old diagnosed with cancer 1973-2000. Linked birth certificates identified first subsequent live offspring (n=470). Comparison subjects were identified from remaining birth certificates, frequency-matched on year and age at fatherhood, and race/ethnicity (n=4150). MAIN EXPOSURE: Cancer diagnosis prior to age 20. OUTCOME MEASURES: Pregnancy and infant outcomes identified from birth certificates. RESULTS: Compared with infants born to unaffected males, offspring of cancer survivors had a borderline risk of birth weight <2500 g (RR 1.43, 95% CI 0.99-2.05), with risk associated most strongly with younger age of cancer diagnosis and exposure to any chemotherapy (RR 1.96, 95% CI 1.22-3.17) or radiotherapy (RR 1.95, 95% CI 1.14-3.35). However, they were not at risk of being born prematurely, small for gestational age, having malformations or an altered male:female sex ratio. Overall, female partners of male survivors were not more likely to have maternal complications recorded on birth records versus the comparison group. However, preeclampsia was associated with some cancers, especially central nervous system tumors (RR 3.36, 95% CI 1.63-6.90). CONCLUSIONS: Most pregnancies resulting in live births among partners of male childhood cancer survivors were not at significantly greater risk of complications versus comparison subjects. The possibility of a paternal component affected by prior cancer history influencing predisposition towards some adverse perinatal outcomes merits further investigation

    Pregnancy outcomes in female childhood and adolescent cancer survivors: a linked cancer-birth registry analysis

    Objective: To compare birth outcomes among childhood and adolescent female cancer survivors who subsequently bear children, relative to those of women without cancer history. Design: Retrospective cohort study. Setting: 4 U.S. regions. Participants: Cancer registries identified girls <20 years, diagnosed with cancer 1973-2000. Linked birth records identified first live births after diagnosis (n=1898). Comparison subjects were selected from birth records (n=14278). Cervical/genital tract cancer cases were analyzed separately. Main Exposure: Cancer diagnosis <20 years. Outcome Measures: Infant low birth weight, preterm delivery, sex ratio, malformations, mortality, delivery method; maternal diabetes, anemia, preeclampsia. Results: Childhood cancer survivors’ infants were more likely to be preterm (relative risk [RR] 1.54, 95% CI 1.30-1.83) and weigh <2500 g (RR 1.31, 95% CI 1.10-1.57). For cervical/genital cancer patients’ offspring, estimates were 1.33 (95% CI 1.13, 1.56), and 1.29 (95% CI 1.10-1.53), respectively. There were no increased risks of malformations, infant death, or altered sex ratio, suggesting no increased germ cell mutagenicity. In exploratory analysis, bone cancer survivors had an increased risk of diabetes (RR 4.92, 95% CI 1.60-15.13), and anemia was more common among brain tumor survivors (RR 3.05, 95% CI 1.16-7.98) and childhood cancer survivors with initial treatment of chemotherapy only (RR 2.45, 95% CI 1.16-5.17). Conclusions: Infants of female childhood and adolescent cancer patients were not at increased risk of malformations or death. Increased occurrence of preterm delivery and low birth weight suggest close monitoring is warranted. Increased diabetes and anemia among sub-groups have not been reported, suggesting areas for study
