Koncem června se z iniciativy francouzské ambasády uskutečnila návštěva tří nositelů Nobelovy ceny v Praze - byli to chemici Jean-Marie Lehn a Jean-Pierre Sauvage a fyzik Serge Haroche. Během tří dnů jsme měli možnost se s nimi potkávat nejen při "klasických " přednáškách, ale i na několika netradičních akcích. and Jan Valenta.
Quaternary faulting in the western part of the Gulf of Corinth has been evidenced by geology and geomorphology, as well as by seismic recording. A series of three main normal fault segments are aligned in a steep southern coastal zone of the gulf. These fault segments, 15 to 25 km long, have an average strike of 90° - 105° and a northward dip of about 50° - 75°. Selected fault points were equipped with 3-D crack gauges TM71 during 2002 to monitor movements along the fault planes here, as well as on another fault cutting through the small island of Trizonia near the opposite northern shore of the gulf. Results of the monitoring present relative displacements induced by active tectonic movement s. Generally, the movements recorded on the faults are characteristic of an aseismic linear creep in vertical, i.e. upliftin g/subsiding in rates of mm per year due to uplifts of the Peloponnesian Peninsula. In 2003 a thr ee months long period of fast acceleration of movements was recorded. During this acceleration phase displacements changed to skew uplifting/subsiding with a left-lateral horizontal component. Moreover, horizontal rotation of monitored blocks corresponding to a sy stematic westwards opening of the Gulf was observed with only single eastward opening episodes., Josef Stemberk and Blahoslav Košťák., and Obsahuje bibliografické odkazy
Šumava lakes have been recovering over the last 30 years from acidification caused by high atmospheric deposition of sulphur and nitrogen. Regeneration was manifested by decreasing acidity and increasing biodiversity (except for fish). It was temporarily interrupted by Spruce Bark Beetle (Ips typographus) infestation in lake catchments. Spruce defoliation and changes in light and humidity conditions caused enhanced mineralization of soil humus layer resulting in nitrate leaching and also partial acidification (only temporary, within a few decades the lakes will profit from the release of nitrogen from the ecosystem). and Jakub Hruška a kol.
