Contribution à la compréhension des relations entre calcarénites et calcaires à rudistes du Barrémien inférieur dans le Vercors méridional (sud-est d…

2006

12 pages; Ce travail porte sur les calcaires à rudistes (Monopleuridae et Requienidae du Barrémien inférieur et base du Barrémien supérieur, essentiellement) du Vercors méridional. Il s'intéresse tout particulièrement aux relations qui existent entre ce faciès et les calcarénites barrémiennes de ce secteur. Les coupes levées et les panoramas réalisés montrent que le motif de dépôt des formations concernées est répétitif et indique, pour ce qui concerne les calcarénites, une diminution de l'hydrodynamisme que l'on interprète comme due à une augmentation de l'accommodation. Les calcaires à rudistes sus-jacents, et qui se mettent en place avant des calcaires argileux ou des dépôts marneux, sem…

Enquête sur la préfiguration et le dispositif de l'acte culinaire à domicile

2017

National audience; La cuisine, à en croire les études, les journaux et les réseaux sociaux, est en vogue Malgré la stabilité du modèle alimentaire français, le temps passé à la préparation culinaire en France a diminué de 18 minutes entre 1986 et 2010. Alors que les discours sanitaires prônent une responsabilisation des consommateurs à l'égard de leur alimentation et les invitent à consommer un régime plus équilibré, nous nous interrogeons sur la place de la cuisine dans le quotidien des français. Dans le cadre d'un projet de thèse sur 3 ans, nous cherchons à saisir les représentations, les freins et les leviers d'action de l'acte culinaire dans la vie quotidienne des français. L'acte culin…

TES microcalorimeter for IXO: From focal plane to anticoincidence detector

2009

The high resolution spectroscopy provides a unique technique to extract fundamental information in X-ray Astrophysics and Cosmology. In order to exploit at the best the capability of carrying out spectroscopy of faint sources, great care must be taken to reduce the background in the main detector. In this paper, we will present the working principle of a TES (Transition Edge Sensor) Microcalorimeter, its application for fine spectroscopy and a novel anticoincidence technique , based itself on a TES detector. Recent results from the first sample of the IXO-anticoincidence detector will be also shown.

Unraveling the three faces of self-esteem: A new information-processing sociometer perspective

2009

Abstract Based on an integration of sociometer theory and information-processing models, the present study investigated the predictive validity of three self-esteem measures: self-report, an implicit association test, and an affective priming task. In a first session, self-esteem measures were obtained from 93 participants. After an interval of four weeks, interpersonal perception ratings were collected in small round-robin groups. Participants were requested to briefly introduce themselves to the group before evaluating one another and indicating how they expected to be evaluated by the others (metaperceptions). As hypothesized, all three self-esteem measures independently predicted the pe…

Aqueous humour (AH) is an important biologic fluid that maintains normal intraocular pressure and contains proteins that regulate the homeostasis of ocular tissues. Any alterations in the protein compositions are correlated to the pathogenesis of various ocular disorders. In recent years, gender-based medicine has emerged as an important research focus considering the prevalence of certain diseases, which are higher in a particular sex. Nevertheless, the inter-gender variations in the AH proteome are unknown. Therefore, this study endeavoured to characterize the AH proteome to assess the differences between genders. Thirty AH samples of patients who underwent cataract surgery were categoriz…

Integrating Keyword Advertising and Dynamic Pricing for an Online Market Place

2014

Keyword Advertising is a main marketing instrument for e-commerce companies in order to generate traffic from search engines on their website. The costs for Keyword Advertising are determined in an auction that is conducted for every single search query, which is entered in by a user. In case of an online market place, each adlink provided by the search engine refers to an ordered list of products on the website of the online market place. Hereby, the price of the product is oftentimes one important criteria for the user when deciding for one or the other product from the list. However, existing models assume the price of products to be exogeneous. By taking into account the prices of linke…

Monte Carlo simulation of many-arm star polymers in two-dimensional good solvents in the bulk and at a surface

1991

A Monte Carlo technique is proposed for the simulation of statistical properties of many-arm star polymers on lattices. In this vectorizing algorithm, the length of each arml is increased by one, step by step, from a starting configuration withl=1 orl=2 which is generated directly. This procedure is carried out for a large sample (e.g., 100,000 configurations). As an application, we have studied self-avoiding stars on the square lattice with arm lengths up tol max=125 and up tof=20 arms, both in the bulk and in the geometry where the center of the star is adsorbed on a repulsive surface. The total number of configurations, which behaves asN∼l γ G–1μ fl , whereμ=2.6386 is the usual effective…

Tenfold increase in efficiency from a reference blue OLED

2018

Abstract Starting from a reference single-layer light-emitting diode based on the blue phosphorescent bis-cyclometallated iridium complex FIrpic as guest, hosted in a PVK (non-conjugated poly(vynilcarbazole)) matrix, different strategies are followed to improve the efficiency of the devices through the combination of solution processed and evaporated layers. Injection of charges from the electrodes has been varied by using different conductive PEDOT: PSS as hole injection layer and a nanoscale Cs2CO3 interlayer as electron injection and hole-blocking film. Furthermore, a separated electron injection/hole blocking evaporated layer, TPBi or 3TPYMB, is introduced in double-layer devices to enh…

Etherification of Functionalized Phenols with Chloroheteroarenes at Low Palladium Loading: Theoretical Assessment of the Role of Triphosphane Ligands…

2011

The present study highlights the potential of robust tridentate ferrocenylphosphanes with controlled conformation as catalytic auxiliaries in CO bond formation reactions. Air-stable palladium triphosphane systems are efficient for selective heteroaryl ether synthesis by using as little as 0.2 mol% of catalyst. These findings represent an economically attractive and clean etherification of functionalized phenols, electron-rich, electron-poor and para-, meta- or ortho-substituted substrates, with heteroaryl chlorides, including pyridines, hydroxylated pyridine, pyrimidines and thiazole. The etherification tolerates very important functions in various positions, such as cyano, methoxy, amino, …
