- L'e-santé européenne est encore morcelée
Les médecins généralistes européens adoptent peu à peu les nouvelles technologies pour le suivi des patients. L'usage de la télémédecine et les échanges de données transfrontaliers restent cependant encore confidentiels. Publié le 28 Avril 2008 Photo E-Santé La moitié des praticiens européens possède une connexion haut-débit. Cette statistique flatteuse cache une disparité forte dans l'accès et l'utilisation des technologies dites de l'information et de la communication sur le Vieux Continent. C'est ce qui ressort d'une étude réalisée par la Commission européenne

It came as a great surprise to most [...] that nature had beaten humans to the punch by creating the world’s first nuclear reactors. Indeed, he argued, nature had a two-billion-year head start. Fifteen natural fission reactors have been found in three different ore deposits at the Oklo mine in Gabon, West Africa. These are collectively known as the Oklo Fossil Reactors.

It is currently suited to us mammals—hence the high diversity of mammals alive today|Two not-so-ancient versions, in astrobiological timescales, of our “Earth-like atmosphere” very nearly wiped out our furry ancestors some 250 mil.yrs ago and then tried again some 200 mil.yrs ago. If a small premammal named Thrinaxodon, whose delicate skulls have been collected in lowest Triassic strata, had not survived, what would life on Earth be like now? Perhaps we would have a diverse and unbelievably beautiful world of birds, in the air, on the ground, diving deeply into the sea, and perhaps they would be the dominant animals on Earth.

Abstract The Propulsive Small Expendable Deployer System (ProSEDS) space experiment will demonstrate the use of an electrodynamic tether propulsion system. The flight experiment is a precursor to the more ambitious electrodynamic tether upper stage demonstration mission which will be capable of orbit raising, lowering and inclination changing—all using electrodynamic thrust. ProSEDS, which is planned to fly in 2000, will use the flight-proven Small Expendable Deployer System (SEDS) to deploy a tether (5-km bare wire plus 15-km spectra) from a Delta II upper stage to achieve ∼0.4N drag thrust, thus deorbiting the stage. The experiment will use a predominantly ‘bare’ tether for current collection in lieu of the endmass collector and insulated tether

This gruesome figure was cast from the corpse of a murderer, taken straight from the gallows to be nailed to a cross and flayed in order to settle an artistic debate. Three Royal Academicians - the sculptor Thomas Banks and painters Sir Benjamin West and Richard Cosway - conducted this experiment to prove their belief that most depictions of the Crucifixion were anatomically incorrect. In 1801 the three artists approached the eminent surgeon, Joseph Constantine Carpue, for his help in finding a suitable subject. The only corpses available for dissection at this time were those of executed criminals but, on October 2nd, an opportunity arose when Carpue was called to Chelsea Hospital. One of the captains, named James Legg, had been arguing with a fellow pensi

What is a self-illustrating phenomenon? A self-illustrating phenomenon is an image that is generated automatically as a result of an experiment. More importantly, it is an image that exposes the phenomenon behind the observation. It often represents an answer to a question. Here is an example. Ernst Chladni, a musician and amateur scientist, found a way to make visible the vibrations caused by sound waves. He covered metal and wooden plates with sand and ran a violin bow against them. When the plate vibrates, sand collects at the stationary nodes, having been shaken from the moving regions. These nodes are the zero-crossings of the standing wave that produces the sound. Being a musician, he was interested in the theory of sounds and he used the tools at his

New observations from NASA's Spitzer Space Telescope strongly suggest that infrared light detected in a prior study originated from clumps of the very first objects of the Universe. The recent data indicate this patchy light is splattered across the entire sky and comes from clusters of bright, monstrous objects more than 13 billion light-years away. "We are pushing our telescopes to the limit and are tantalizingly close to getting a clear picture of the very first collections of objects," said Dr. Alexander Kashlinsky of NASA's Goddard Space Flight Center, Greenbelt, Md., lead author on two reports to appear in the Astrophysical Journal Letters. "Whatever these objects are, they are intrinsically incredibly bright and very different from anything in existe

* Never use very hot water for washing stained garments as this often sets the stains and makes them very difficult or impossible to remove. * Some stains are more easily removed by washing if they are soaked first in cold water, e.g. mud and blood stains, and the brown stain from shoe inner soles. * The use of chemicals is required for removing certain stains. Carry out this treatment before washing. Remove all traces of the chemical. * To apply a stain removing agent to fabric, place a fold of clean rag underneath the stain so that any surplus moisture is absorbed. * To prevent a ring forming around the stain, work from the outside of the stain, in an uneven circular shape, towards the centre, dabbing it very lightly with a pad of clean r

The radar scatters a very low-intensity signal across a wide range of frequencies, so a TV or radio tuned to any one frequency would interpret the radar signal as a very weak form of static. "It doesn't interfere because it has a bandwidth that is thousands of times broader than the signals it might otherwise interfere with," Walton said.

Abstract. To understand the three-dimensional ocean circulation patterns that have occurred in past continental geometries, it is crucial to study the role of the present-day continental geometry and surface (wind stress and buoyancy) forcing on the present-day global ocean circulation. This circulation, often referred to as the Conveyor state, is characterised by an Atlantic Meridional Overturning Circulation (MOC) with a deep water formation at northern latitudes and the absence of such a deep water formation in the North Pacific.

In 1942, Walls described the concept of a ‘nocturnal bottleneck’ in placental mammals, where these species could survive only by avoiding daytime activity during times in which dinosaurs were the dominant taxon. Walls based this concept of a longer episode of nocturnality in early eutherian mammals by comparing the visual systems of reptiles, birds and all three extant taxa of the mammalian lineage, namely the monotremes, marsupials (now included in the metatherians) and placentals (included in the eutherians).

in Public bookmarks - Time and symmetry in models of economic markets Lee Smolin (Submitted on 25 Feb 2009)
These notes discuss several topics in neoclassical economics and alternatives, with an aim of reviewing fundamental issues in modeling economic markets. I start with a brief, non-rigorous summary of the basic Arrow-Debreu model of general equilibrium, as well as its extensions to include time and contingency. I then argue that symmetries due to similarly endowed individuals and similar products are generically broken by the constraints of scarcity, leading to the existence of multiple equilibria. This is followed by an evaluation of the strengths and weaknesses of the model generally. Several of the weaknesses are concerned with the treatments of time and contingency. To address these we discuss a class of agent based models. Another set of issues has to do
