The ranking, headed by the UGR, presents data for countries and journals and can be filtered according to large knowledge areas (27), thematic categories (295), country/journal and years (since 1996 to 2006). An additional combination permits to arrange the ranking according to different indicators: SJR, citations per document, h-index, journals titles, documents, quotable documents and total of citations; with the possibility of establishing a minimum level for all of them. SJR is based on the ‘Page Rank’ algorithm to weight citations according to those received by the citing publication.
The SCImago Group has published the new “SCImago journal & Country rank: A new site, two new rankings” in the November - December issue 2007 (vol16, n. 6) of the journal "The Information Professional", as well as the open access article, which can be gratuitously downloaded in pdf and html on: http://elprofesionaldelainformacion.metapress.com

SCImago Research Group
The SCImago Group, directed by Professor Félix de Moya Anegón (University of Granada), is composed of researchers of the universities Carlos III and Alcalá of Madrid, of Extremadura and of Granada. They have worked on the use of scientometric indicators as tools that permit to place a country, an institution, a thematic area or a researcher in the world context of scientific production. They have carried out the project “Science Atlas”, in which the Group has focused its work since 1998.
Thomson Scientific ISI
The Institute for Scientific Information -ISI offers the scientific community a citation database including thousands of journals -the Science Citation Index (SCI). The database offers the possibility of identifying the most frequently cited articles, as well as the source of the citation. The ISI allows to know, in addition, the impact of each indexed scientific journal and, therefore, their valuation among the scientific community.
All over the world, the bibliometric indicators of the ISI have been used to analyse the scientific production and to direct decision taking in scientific and technological public policies.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
