EMOIS Nancy 2011 - A quelle distance de chez soi se fait-on hospitaliser?
A quelle distance de chez soi se fait-on hospitaliser ?
Auteur(s) : F. Evain, C. Minodier, Direction de la Recherche, des Études, de l’Évaluation et des Statistiques - Ministère chargé de la santé, Paris
Introduction : L’accessibilité géographique aux services de santé peut être définie de deux façons différentes : théorique en mesurant la distance à l’établissement le plus proche et effective en calculant la distance réellement parcourue par un patient pou
Modèle expérimental de la respiration humaine
A chacune de nos respirations, les poumons se gonflent ou se dégonflent pour inspirer ou expirer de l’air. Or les poumons n’ont pas de muscles. Quel est le phénomène qui leur permet de se dilater ?
Episode 93: What Role Stem Cells in Leukaemia?
Physician and researcher David Curtis outlines current understanding of the complex relationship between stem cells and cancer -- in particular leukemia.
Euston Arch AA98_05420
EUSTON ARCH, Euston Station, Euston Road, Camden Town, London. Traffic outside the Euston Arch. The arch was designed by Philip Hardwick in 1837 as part of a screen and portico around the station forecourt. It was demolished in 1963. Photographed in 1960 by Eric de Mare.
Aladdin Matrix and Finite Element Environment
"Aladdin is a computational toolkit for the interactive matrix and finite element analysis of large engineering structures." It is being developed at the University of Maryland Institute for Systems Research and is funded by the National Science Foundation and Federal Highway Administration. Aladdin has numerous functions, including matrix arithmetic, structural analysis, and mechanics of finite elements. The software is excellent for use by both student and professional engineers. Extensive inf
The Internet Guide is a no-nonsense site intended for Internet newbies. It consists of several short articles that discuss the basics of Internet navigation, common terms and phrases, Netiquette, and much more. Some specific technologies are also mentioned, such as Telnet and newsgroups. The Guide occasionally refers to various products or services; however, it does not endorse any particular company, instead offering a list of several potential choices. A particularly enlightening section defin
Drilling for oil in the Arctic National Wildlife Refuge (ANWR) in Alaska has been a topic of debate for many years. Although initial exploratory drilling has not yet been authorized by the government, this site presents some technologies that could eventually be used to find and extract oil without damaging the land. Nine articles describe different drilling methods, spill prevention tactics, exploration techniques, and more. One topic is 3D reflective seismic technology, which is used to help a
Museum of Science's Educator Resource Center
The Museum of Science's Educator Resource Center (ERC), based in Boston, MA, offers this website providing educators with "recommended and institutional Museum materials, all mapped to national and state standards, in order to increase the quality of science, technology, and engineering education." The collection includes a wealth of curriculum materials and science project resources focused specifically on engineering and technology education. Each lesson is evaluated in terms of usability, tea
Water Research Network
Self-described as a "multidisciplinary database of research, researchers, and institutions dealing with fresh water issues all over the world," the Water Research Network (WRN) is a product of collaboration between the University of Bergen, Norway, the Norwegian Research Council, and the Government of the Netherlands. Active since October 2001, WRN invites researchers from various disciplines to submit information about their water research projects (free registration is required). While the sit
The Physics Classroom
Hosted by Study Works Online and written by science teacher Tom Henderson, The Physics Classroom is an online physics tutorial written for high school physics students. Through individual lessons and accompanying quizzes, this very informative site includes a physics tutorial that covers everything from Newton's Laws to Refraction. The Multimedia Physics Studio portion of the site gives excellent animations and movies that allow students to reinforce their learning by visualizing what is being d
Magplane: Transportation for the Information Age
The Magplane concept involves electromagnetically levitated vehicles designed for fast intra-city travel. This is in contrast to most other systems that focus on intercity travel; the goal of the Magplane system is to connect suburbs and locations up to 250 miles from a central metropolitan area, with travel times of about an hour or less. The Magplane home page offers many details of the system's design and operation. Five technical papers are also presented, which describe some of the engineer
The National Academy of Forensic Engineers (1) provides a short definition of forensic engineering as: "the application of the art and science of engineering in matters which are in, or may possibly relate to the jurisprudence system, inclusive of alternative dispute resolution." Specialty areas in forensic engineering include fire investigation, industrial accidents, product liability, traffic accidents, civil engineering and transportation disasters, and environmental systems failures. For exa
Physical Science Information Gateway: Training
Another helpful resource from the Physical Science Information Gateway (last mentioned in the September 14, 2001 Scout Report , the Training Web site contains "free "teach yourself" Internet tutorials aimed at students, researchers and other members of staff who want to get the most out of the Internet". The topics covered include chemistry, earth science, physics, and the history and philosophy of science. Users get to tour key internet sites on each of the general topics, learn how to search f
Soap and Bubbles
The first Web site, from The Soap and Detergent Association, is called Soaps and Detergents (1). Visitors learn about the chemistry of soap and detergent, their history, how they're manufactured, and more. The easily read text and fun illustrations make this site a great place to start for this topic. The next site, called Bubble Engineering (2), is provided by Bubble Town. The page describes the physics of a cone-shaped bubble blowing device and how its shape reduces the velocity of air being b
Top500 Supercomputer Sites
Twice a year, the Top500 Project releases a list of the 500 sites with the most powerful supercomputers. The purpose of the list is "to provide a reliable basis for tracking and detecting trends in high-performance computing." The latest version was unveiled in June, and this site examines some of the most important developments and newcomers to the list. Most important is the recently constructed Earth Simulator in Japan, which was rated almost five times more powerful than second place. Additi
America's Backyard: Exploring Your Public Lands
America's Backyard: Exploring Your Public Lands is the featured topic of National Geographic's Geography Action! -- an "annual conservation and awareness program designed to educate and excite people about our natural, cultural, and historic treasures." This Web site offers a number of public land-related educational activities, many of the which apply directly to the life sciences. Activities are available for grades K-12, and cover such topics as the role of forests in our daily lives, conserv
The Microbial Ecology Group of Munich's University of Technology has recently launched probeBase, "a comprehensive database containing published rRNA-targeted oligonucleotide probe sequences, DNA microarray layouts and associated information." Users may search for sequences by target organism, which "can assist in the development of new rRNA-targeted oligonucleotide probes for fluorescence in situ hybridization (FISH)," or by probe name for rapidly retrieving published probes targeting desired s
