Chernobyl_disaster_effects
The Chernobyl disaster triggered the release of substantial amounts of radiation into the atmosphere in the form of both particulate and gaseous radioisotopes . It is the most significant unintentional release of radiation into the environment to date, with the possible exception of the Fukushima Diaster. It has been suggested that the radioactive contamination caused by the Chernobyl disaster greatly exceeded that of the atomic bombing of Hiroshima and Nagasaki in 1945. [ citation needed ] However, the work of the Scientific Committee on Problems of the Environment (SCOPE) suggests that the two events cannot be directly compared, with a number suggesting that one was x times larger than the other; the isotopes released at Chernobyl tended to be longer-lived than those released by a bomb detonation, producing radioactivity curves that vary in shape as well as size.

Taxonomy (from Greek : τάξις taxis "arrangement" and Greek : νομία nomia "method" [ 1 ] ) is the science of identifying and naming species, and arranging them into a classification . [ 2 ] [ 3 ] The field of taxonomy, sometimes referred to as "biological taxonomy", revolves around the description and use of taxonomic units, known as taxa (singular taxon ). A resulting taxonomy is a particular classification ("the taxonomy of ..."), arranged in a hierarchical structure or classification scheme . An example of a modern classification is the one published in 2009 by the Angiosperm Phylogeny Group for all living flowering plant families (the APG III system ). [ 4 ]

GeoTools ist eine freie Java - Bibliothek zur Bearbeitung und Darstellung geografischer Daten. Die GeoTools-Bibliothek verwendet die JTS Topology Suite und implementiert die Spezifikation Simple Features Access des Open Geospatial Consortium (OGC). Die Bibliothek wird sowohl für Web-GIS-Projekte ( WFS , WMS ) wie GeoServer als auch für Desktop-GIS-Projekte wie uDig oder AtlasStyler [1] eingesetzt.
