Bridging the gap between social tagging and semantic annotation: E.D. the Entity Describer

Semantic annotation enables the development of efficient computational methods for analyzing and interacting with information, thus maximizing its value. With the already substantial and constantly expanding data generation capacity of the life sciences as well as the concomitant increase in the knowledge distributed in scientific articles, new ways to produce semantic annotations of this information are crucial. While automated techniques certainly facilitate the process, manual annotation remains the gold standard in most domains. In this manuscript, we describe a prototype mass-collaborative semantic annotation system that, by distributing the annotation workload across the broad community of biomedical researchers, may help to produce the volume of meaningful annotations needed by modern biomedical science. We present E.D., the Entity Describer, a mashup of the Connotea social tagging system, an index of semantic web-accessible controlled vocabularies, and a new public RDF database for storing social semantic annotations

Solutions for Financial Inclusion: Serving Rural Women

This document presents a CaseStudy for solutions for financial inclusion. Using Uganda as a CaseStudy, Women's World Banking set out to better understand the needs of rural women and to use the research and lessons learned there to make recommendations on the design and delivery of microfinance products within Uganda and throughout sub-Saharan Africa. The research highlights the specific gender-based social, cultural and legal barriers that rural women face in accessing and using financial services and examines operational challenges to effectively serving this market

L'impression 3D au service du génie des procédés : optimisation morphologique de structures complexes aux propriétés d'usages maîtrisées

Ces travaux de thèse apportent une contribution à la problématique de la conception de nouveaux objets de génie des procédés réalisés par fabrication additive. Plus particulièrement, une méthode pour la conception d’internes structurés complexes aux propriétés d’usage maîtrisées a été proposée. Des structures innovantes à géométrie complexe, ayant des propriétés géométriques et morphologiques intéressantes, pour des applications de mélange et de séparation ont été conçues, produites, caractérisées et modélisées. Ainsi, un garnissage à base de fils de section cylindrique est développé pour des applications en tant que contacteur gaz-liquide, alors qu’un ruban hélicoïdal est conçu pour des réacteurs oscillatoires continus. Dans un premier temps, différentes configurations ont été imprimées et étudiées d’un point de vue expérimental en modifiant les propriétés géométriques des structures, puis, des méthodes de caractérisation ont été appliquées sur ces internes pour mesurer leurs performances (capacité et efficacité en transfert de matière ou pourcentage du mélange). Dans un second temps, des travaux de modélisation mathématique, en se basant sur les données expérimentales et sur de l’analyse dimensionnelle, ont abouti à des corrélations adimensionnelles permettant de prédire les performances de ces internes en fonction des paramètres morphologiques. Enfin, des stratégies d’optimisation ont été mis en place sur la base de ces modèles afin d’être capable d’optimiser les paramètres géométriques en fonction des propriétés d’usage attendues

Oxidation Activity of Catalyst 3-7A Toward Formaldehyde, Hydrogen Cyanide, And Some Alkane Gases

The activity of Catalyst 3-7A toward the oxidation of formaldehyde, hydrogen cyanide, methane, propane, and isobutene was examined at temperatures between 25°C and 400°C. The catalyst consists of palladium(II) and copper (II) salts impregnated on an alumina support. The oxidation measurements were made primarily with gas chromatographs, although form aldehyde and hydrogen cyanide were also examined using the colorimetric fushsin method and Liebig titrations, respectively. Catalyst 3-7A demonstrated appreciable activity toward the oxidation of all gases studied except formaldehyde where there was no evidence of oxidation. The latter result is quite unexpected since aldehydes are more easily oxidized than alkanes. It is suggested that the inactivity of Catalyst 3-7A toward formaldehyde is attributed to the lack of moisture which is required by the catalyst during oxidation. All oxidation reactions are believed to occur via a Qacker-type process under pseudo-first order conditions with the palladium(II) concentration maintained constant via the presence of copper (II) which oxidizes metallic palladium, the product in the oxidation reaction. The oxidation products in all the gases examined are believed to be carbon dioxide and water except for hydrogen cyanide where an additional product containing nitrogen should be formed but could not be detected with the gas chromatograph. Rate constants (reported in parenthesis) at 400°C for the following gases are hydrogen cyanide (\u3e26.2 sec-1), methane (6.5-6.6 sec-1), propane (\u3e12.8 sec-1), and isobutene (\u3e15.7 sec-1). These results show that hydrogen cyanide is the most active gas to be oxidized by the catalyst excluding carbon monoxide which is the test gas used I our system and has been previously determined to demonstrate the greatest activity with the catalyst. The three alkane gases show an order of oxidation reactivity which lends some support for ruling out an anionic mechanism since tertiary C-H bonds were found to be more reactive than secondary C-H bonds which in turn were shown to be more reactive than primary C-H bonds. A comparison of Catalyst 3-7A with other catalysts reported in the literature which show similar oxidation behavior with gases could not be made due to lack of data regarding their experimental conditions
