Morbidité et mortalité cardiovasculaire dans l'Unité de Soins Intensifs de Cardiologie CHU Point G'
No full textLa fréquence des hospitalisations dues aux urgences cardio-vasculaires, dans l'unité de soins intensifs de la cardiologie CHU Point G de Bamako et l'absence d'étude abordant le sujet ont été les principales sources de motivations de ce travail dont l'objectif était d'étudier les aspects épidémiologique, clinique et évolutif. Il s'agissait d'une étude rétrospective et descriptive allant de Juillet 2012 à Octobre 2014 et portant sur 232 cas d'urgences cardio-vasculaires. Nos constats étaient les suivants : les urgences cardio-vasculaires avaient une prévalence de 20,5% ; l'âge moyen des patients était de 57,63 ans ; le sexe féminin prédominait sur le sexe masculin avec un sex-ratio de 1,03. La classe d'âge modale était la tranche de 61-70 ans .79.2% des patients avaient un niveau de vie socio économique faible .Les syndromes coronaires et les troubles du rythme et de conduction constituaient les groupes nosologiques prééminents avec respectivement 36.63% et 12.5%.Nous avions observé 19.82% de décès dont les patho- logies les plus meurtrières étaient L'AVC sur T4F et l'IC indéterminée. avec 50% de mortalité chacune. A la lumière de ce travail, il apparaît la nécessité de mettre l'accent sur une approche cardiolo- gique, de la mise sur pied d'une unité de soins intensifs cardiaques avec des normes interna- tionales pour une prise en charge optimale des patients
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Evaluation dataset and methodology for extracting application-specific taxonomies from the wikipedia knowledge graph
No full textIn this work, we address the task of extracting application-specific taxonomies from the category hierarchy of Wikipedia. Previous work on pruning the Wikipedia knowledge graph relied on silver standard taxonomies which can only be automatically extracted for a small subset of domains rooted in relatively focused nodes, placed at an intermediate level in the knowledge graphs. In this work, we propose an iterative methodology to extract an application-specific gold standard dataset from a knowledge graph and an evaluation framework to comparatively assess the quality of noisy automatically extracted taxonomies. We employ an existing state-of-the-art algorithm in an iterative manner and we propose several sampling strategies to reduce the amount of manual work needed for evaluation. A first gold standard dataset is released to the research community for this task along with a companion evaluation framework. This dataset addresses a real-world application from the medical domain, namely the extraction of food-drug and herb-drug interactions

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Molecular simulation of a model of dissolved organic matter
No full textA series of atomistic simulations was performed to assess the ability of the Schulten dissolved organic matter (DOM) molecule, a well-established model humic molecule, to reproduce the physical and chemical behavior of natural humic substances. The unhydrated DOM molecule had a bulk density value appropriate to humic matter, but its Hildebrand solubility parameter was lower than the range of current experimental estimates. Under hydrated conditions, the DOM molecule went through conformational adjustments that resulted in disruption of intramolecular hydrogen bonds (H-bonds), although few water molecules penetrated the organic interior. The radius of gyration of the hydrated DOM molecule was similar to those measured for aquatic humic substances. To simulate humic materials under aqueous conditions with varying pH levels, carboxyl groups were deprotonated, and hydrated Na(+) or Ca(2+) were added to balance the resulting negative charge. Because of intrusion of the cation hydrates, the model metal-humic structures were more porous, had greater solvent-accessible surface areas, and formed more H-bonds with water than the protonated, hydrated DOM molecule. Relative to Na(+), Ca(2+) was both more strongly bound to carboxylate groups and more fully hydrated. This difference was attributed to the higher charge of the divalent cation. The Ca-DOM hydrate, however, featured fewer H-bonds than the Na-DOM hydrate, perhaps because of the reduced orientational freedom of organic moieties and water molecules imposed by Ca(2+). The present work is, to our knowledge, the first rigorous computational exploration regarding the behavior of a model humic molecule under a range of physical conditions typical of soil and water systems
