The ongoing development of landslide prone regions increases future potential losses caused by landslide occurrence. The first step towards landslide mitigation on a regional scale is a susceptibility assessment. This study focuses on the area surrounding the regional capital of Zlín, in the Outer Western Carpathians. The city is located in the flysch highlands. Statistical analysis of the distribution of landslide scarps was undertaken in relation to various preparatory factors (geology, slope angle, slope aspect, slope curvature, distance from closest stream). This analysis provided insights into the main initiating factors and allowed our results to be compared with other studies in similar regions. Thereafter, a regional landslide susceptibility assessment was undertaken. The model performance was evaluated with respect to the landslide information used during its preparation and with a separate validation dataset. The results show that the main predisposing factors are the claystone rich bedrock unit, thick accumulations of slope sediments, and slope angles between 10° and 15°. The possible application of the presented results for urban planning purposes is also outlined., Jan Klimeš and Roman Novotný., and Obsahuje bibliografii
V České republice vzniká první evropská laserová výzkumná infrastruktura určená pro výzkum a aplikační projekty v oblasti interakce světla s hmotou. Očekávají se od ní průlomové objevy v materiálech, nanotechnologiích, lékařství, zobrazování a diagnostice, optice, ale i nové technologie využitelné v průmyslu. Jak je u podobných zařízení běžné, stane se též atraktivním místem pro výchovu doktorandů, vědců a inženýrů. S laserovými centry ELI Beamlines a HiLASE i s rozvojovým potenciálem „vědeckého trojměstí“ na jižním okraji Prahy se 26. února 2015 seznámili ministr financí Andrej Babiš a vládní zmocněnkyně pro udržitelnost výzkumných center MŠMT Eva Kislingerová. and Marina Hužvárová.

We first recall the main features of Mach's radical attitude to the "philosophy of science", illustrated best by his criticism of absolute space and time, and discuss the impact of Mach's ideas on the birth of special and general relativity. The experiment to demonstrate "Machian effects" of dragging of inertial frames by a rotating body (carried out by four gyroscopes placed in an orbit around the Earth) was conceived in 1959 but only in 2014 was the satellite launched. The last results from the experiment were finally summarised at the end of 2015: they confirm the dragging as predicted by general relativity with an accuracy of 19 %. We show that a rotating black hole can even drag magnetic field lines and indicate possible astrophysical meaning of processes of this type. in the concluding parts, our investigation of dragging effects by gravitational waves and the study of Mach's principle in the context of cosmology, obtained in collaboration with Donald Lynden-Bell (Cambridge) and Joseph Katz (Jerusalem), are briefly reviewed., Jiří Bičák., and Obsahuje bibliografii
