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
Researchers and academic and institutional authorities must support this initiative now with specific facts. For further suggestions or comments, those interested should get in touch with the authors by e-mail: firstname.lastname@example.org
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.

World's thinnest hologram paves path to new 3-D world

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
