Academic Materials Research Laboratory of Painted Artworks (ALMA) is a joint workplace of the Academy of Fine Arts in Prague (AFA) and the Institute of Inorganic Chemistry of the Academy of Sciences of the Czech Republic (IIC ASCR). This is a scientific laboratory focused on the Czech cultural heritage. Combining the branches of the natural sciences, art and the history of art, ALMA seeks to deepen the knowledge of painting materials and techniques. The knowledge acquired is integrated into a complete evaluation of painted art works by origin, age, and authenticity. The ALMA Laboratory develops instrumental materials analysis methods and interprets the results in the context of art history and history of materials technology. and Silvie Švarcová, David Hradil.
Secondary deformations are ground movements occurring in areas of ceased underground mining. These are associated with delayed readjustment of rock mass resulting in subsidence, discontinuous deformations (sinks, cracks, etc.) due to destruction of underground, usually shallow, workings, and elevation of ground surface in response of rock mass to rising groundwater levels following the end of mine water drainage. Comparative analysis of secondary deformations in two former mining areas in the first period after cessation of underground hard coal mining is the subject of this study. We used ERS-1/2 and Envisat satellite radar interferometry data processed with PSInSAR technique and GIS to map vertical (in satellite’s line of sight, LOS) movements of the surface and analyse them in relation to location of coal fields and underground water table rise. In the study, two areas have been compared, the Ostrava city in the Czech part of the Upper Silesian Basin and the Wałbrzych Coal Basin in Poland. The results of analyses based on the results of PSInSAR processing between 1995 and 2000 for the Wałbrzych site indicate uplift (up to +12 mm/year) in closed parts of coal fields and subsidence (up to -8 mm/year) in areas of declining mining. Results of PSInSAR analysis over the Ostrava site indicate decaying subsidence after mine closures in the rate of up to -6 mm/year during 1995-2000. Residual subsidence and gentle uplift have been partly identified at surroundings of closed mines in Ostrava from 2003-2010 Envisat data. In Wałbrzych gentle elevation has been determined from 2002 to 2009 in areas previously subsiding. and Blachowski Jan, Jiránková Eva, Lazecký Milan, Kadlečík Pavel, Milczarek Wojciech.
Astronomické informace pro profesionály jsou v dnešní době bez problému dostupné v odborných časopisech, databázích naměřených dat, knihách a internetových publikacích. Kde však může získat kvalitní nezkreslené informace širší veřejnost? Televizních astronomických pořadů je jako šafránu, a ty, které zbyly, jsou mnohdy kombinovány s astrologií, věštectvím a jinými pavědami. V rozhlase zůstaly pořady Meteor a Planetárium, ale ty se netýkají jen astronomie. Z ryze astronomických vědecko-populárních časopisů nám zbyl už jediný - Astropis - a doufejme, že přežije i nadále. Většina lidí se proto obrací k internetu. Pro laika je někdy obtížné odlišit kvalitní informace od balastu, a proto přinášíme čtenářům stručný výběr některých webů s hodnotnými astronomickými informacemi. and Petr Kulhánek.
