This report outlines which resources were integrated, how the knowledge base was constructed using free and open source triple store technology, how it can be queried using the W3C Recommended RDF query language SPARQL [SPARQL], and what resources and inferences are involved in answering complex queries. While the utility of the knowledge base is illustrated by identifying a set of genes involved in Alzheimer's Disease, the approach described here can be applied to any use case that integrates data from multiple domains. 2008-06-12T08:29:11Z http://www.oregonfossilguy.com/ 2008-05-19T00:02:00Z http://www.oregongeology.com/ 2008-05-18T23:56:36Z http://www.paleolands.org/ We’ll take you and your family on a customized day hike to collect fossils, touch a 44-million-year-old tree, visit a lakeshore 33 million years old, or volunteer to assist paleontologists in their research. 2008-05-18T23:42:07Z http://www.planetastronomy.com/articles/mesure-distance.htm 2008-05-17T16:52:44Z http://www.nasa.gov/mission_pages/voyager/termination_shock.html 2008-05-17T14:02:12Z http://news.bbc.co.uk/2/hi/science/nature/7399226.stm 2008-05-17T00:31:40Z http://paleodb.org/cgi-bin/bridge.pl The Paleobiology Database is an international scientific organization run by paleontological researchers from many institutions.

There are three such ecosystems found on Earth that would conceivably be a basis for life on Enceladus. Two are based on methanogens, which belong to an ancient group related to bacteria, called the archaea -- the rugged survivalists of bacteria that thrive in harsh environments without oxygen. Deep volcanic rocks along the Columbia River and in Idaho Falls host two of these ecosystems, which pull their energy from the chemical interaction of different rocks. The third ecosystem is powered by the energy produced in the radioactive decay in rocks, and was found deep below the surface in a mine in South Africa. 2008-04-07T21:00:32Z http://www.milk.com/wall-o-shame/heavy_boots.html 2008-03-29T19:30:29Z http://www.physics.usyd.edu.au/~gekko/pinwheel.html A spectacular, rotating binary star system is a ticking time bomb, ready to throw out a searing beam of high-energy gamma rays – and Earth may be right in the line of fire. 2008-03-06T21:45:06Z http://www.wired.com/science/discoveries/news/2008/01/synthetic_genome 2008-01-25T21:38:25Z http://www.wired.com/science/planetearth/news/2008/01/gm_insects 2008-01-25T21:32:22Z http://en.wikipedia.org/wiki/Tulip_mania 2008-01-25T15:05:42Z http://www.apollon.uio.no/vis/art/2007_4/Artikler/The_Tree_of_Life 2008-01-25T08:43:48Z http://messenger.jhuapl.edu/gallery/sciencePhotos/image.php?gallery_id=2&image_id=117 2008-01-16T23:32:42Z http://messenger.jhuapl.edu/ 2008-01-15T14:02:08Z http://www.saudiaramcoworld.com/issue/200405/what.was.jiroft..htm 2008-01-06T03:25:00Z http://fr.wikipedia.org/wiki/Giovanni_Battista_Belzoni 2008-01-04T01:53:44Z http://www.bbc.co.uk/science/horizon/1999/nasca_script.shtml On a barren desert in South America is one of the greatest archaeological wonders of the world.

Il faut toutefois être très présent les premières semaines pour éviter l’assèchement au moment du repiquage. La croissance de l’arbre sera par ailleurs très influencée par les soins ultérieurs reçus par l’arbre (désherbage, paillage, arrosage, engrais). Faire un trou de 60 cm x 60 cm et 50 cm de profondeur. Mettre au fond la terre qui était au dessus et rajouter si possible du fumier. Couper la partie inférieure du pot inciser la partie latérale du pot. Insérer le pot dans le trou sans retirer le plastique. Mettre un peu de terre puis retirer le plastique. Mettre encore de la terre puis tasser fermement. Pour améliorer le taux de survie, on peut planter une dizaine de tiges de mil séchées autour du plant, ou une gaine IRRIGASC. On peut également couper un partie des feuilles pour limiter l’évapotranspiration et ne garder que la partie supérieure. Dans le même objectif, recouvrir le sol d’herbes ou de tiges de mil a pied de l’arbre (paillage). Une famille peut au maximum s’occuper de 100 arbres, étant donné qu’elle doit dans le même temps être dans les champs de mil.

In the mid-1960s, Ray Davis and John Bahcall thought they had a way. Drawing on advances made by other physicists earlier in the century, they intended to use notoriously elusive particles called neutrinos to verify ideas about the sun's inner workings. Theorist Bahcall calculated the number of neutrinos they expected to find, and experimentalist Davis tried to catch them. But for more than three decades, their results didn't jibe. In the chronology below, follow the case of the missing neutrinos, which ultimately led not only to a triumph for Davis and Bahcall but also to a surprising breakthrough in particle physics. 2006-02-17 http://newsvote.bbc.co.uk/mpapps/pagetools/print/news.bbc.co.uk/2/hi/science/nature/4679220.stm Astronomers have for the first time put some real numbers on the physical characteristics of dark matter. 2006-02-15 http://www.the325project.org/ 2006-01-30 http://www.arte-tv.com/fr/search__results/1095558.html 2006-01-29 http://arethuse1.free.fr/ 2006-01-29 http://www.pbs.org/wnet/secrets/flash/catastrophe1_script.html 2005-12-19 http://www.pbs.org/wnet/secrets/flash/catastrophe2_script.html 2005-12-19 http://stardust.jpl.nasa.gov/ On January 15, 2006, after more than 7 years and billions of miles of travel through space, the Stardust spacecraft will finally return to Earth with some precious cargo -- pristine samples of comet and interstellar dust. 2005-12-08 http://www.esa.int/SPECIALS/Results_from_Mars_Express_and_Huygens/SEMTFSULWFE_0.html 2005-12-01 http://www.esa.int/SPECIALS/Results_from_Mars_Express_and_Huygens/SEMA1UULWFE_0.html 2005-11-30 http://www.esa.int/SPECIALS/Results_from_Mars_Express_and_Huygens/SEM7ZTULWFE_0.html 2005-11-30 http://news.bbc.co.uk/2/hi/science/nature/4467676.stm Scientists believe it collected the debris, but will only be sure when Hayabusa returns to Earth in 2007. 2005-11-27 http://www.ihes.fr/~lafforgue/dem/courriel.html 2005-11-25 http://www.nemrud.nl/ 2005-11-21 http://www.lamap.fr/ 2005-11-19 http://www.pbs.org/wgbh/nova/newton/einstein.html 2005-11-03 http://www.pbs.org/wgbh/nova/sciencenow/dispatches/050707.html 2005-11-02 http://www.pbs.org/wgbh/nova/sciencenow/dispatches/050721.html 2005-11-02 http://species.wikipedia.org/wiki/Main_Page Wikispecies is free.
