Micro-displacement monitoring in Slopy a nd Zbojnícka caves is described. It st arted at the end of 2005 with the use o f verified, stable and sensitive 3D crack gauges TM71 produced by GESTRA Sedloňov. Two gauges were installed in the caves across significant tectonic structures. Registered displacements are pertinent to the last significant earthquake events. The f irst one appeared in March 13, 2006 at Vrbové, M=3.2; and later in August 5-8, 2006, a swarm of 10 quakes M max = 2.2 at Trstín was registered. The results indicated trends of dextral strike-slip displacements across observed fault structures in both of those caves., Miloš Briestenský and Josef Stemberk., and Obsahuje bibliografické odkazy
The paper is focused to the analysis of permanent and epoch-wise GPS networks extending over the region of Slovakia. We considered almost all available GPS data measured in Slovakia and its close surroundings over the period of last 17 years. Our analysis is based on combination of homogenized permanent and epoch-wise network solutions leading to the ITRF2005 related coordinates, velocities and their global covariance matrix. Estimated velocities were further reduced for APKIM2005d plate motion model and submitted to the velocity filtering and smoothing using the least square collocation approach. The obtained homogenized intra-plate velocity field is then used for the surface deformation analysis. The final and partial results of this procedure are discussed in order to extend information about recent regional geo-kinematics of Slovakia., Ján Hefty, Linda Hipmanová, Ľubomíra Gerhátová, Miroslava Igondová and Branislav Droščák., and Obsahuje bibliografii
The paper presents results of epoch satellite GPS and gravimetric measurements performed on the geodynamic network in central part of the Stołowe Mts. between 1993 and 2009. The research results show significant changes of gravity on most of the points and significant horizontal movement of one point in the central part of the area. The results confirm present day activity of the zone where faults Polický, Bělský and Czerwona Woda Fault Zone exists. In addition, they correspond with the studies of seismic activity in this part of the Sudety Mts., Stefan Cacoń, Jan Kapłon, Bernard Kontny, Josef Weigel, Otakar Švábenský and Jiři Kopecký., and Obsahuje bibliografii
The combination method of results of different space geodetic techniques was recently improved and used to process approximately eight-year data obtained by three space geodetic techniques. The results are compared with the results obtained by the old approach of this method and finally with the solutions of ITRF 2005., Vojtěch Štefka., and Obsahuje bibliografii
The spontaneously hypertensive rat (SHR) is the most widely used animal model of essential hypertension an d accompanying metabolic disturbances. Recent advances in sequencing of genomes of BN- Lx and SHR progenitors of the BXH/HXB recombinant inbred (RI) strains as well as ac cumulation of multiple data sets of intermediary phenotypes in the RI strains, including mRNA and microRNA abundance, quantitative metabolomics, proteomics, methylomics or histone modifications, will make it possible to systematically search for genetic variants involved in regulation of gene ex pression and in the etiology of complex pathophysiological traits. New advances in manipulation of the rat genome, including e fficient transgenesis and gene targeting, will enable in vivo functional analys es of selected candidate genes to identify QTL at the molecular level or to provide insight into mechanisms whereby targeted genes affect pathophysiological traits in the SHR., M.

Distributed control and measurement system for evaluation of hydrologic, geomechanical and other parameters has been built up in the medieval ore mine Jeroným. The instrumentation is generally based on commercial measurement and control kit and sensors. Technique of implementation of special sensors, e.g. laser distance meter and/or CCBM probe for measurement of rock massif stress changes, is also described. The distributed system is integrated into the existing seis mic recording station equipped by data transmission via GSM network. Comprehensive monitoring system is modular in order to have possibility to change the system configuration., Jaromír Knejzlík and Zdeněk Rambouský., and Obsahuje bibliografické odkazy
Three year monitoring of micro-displacements on four tectonic fracture planes in a tunnel driven by a milling cutter into granitoids of Bohemian Massif revealed micro-movements that develop in certain trends and impulses. Two investigated fractures are of the Krušné Hory Mts. orientation (NE - SW), other two of Sudeten orientation (NW - SE). These have been found the two prevailing fracture orientations in the massif. Results from all the four fractures indicate trends in overfaulting of southern blocks over the northern ones and a stress state model characteristic of approximate N-S compression with overthrust vergence to N. Besides, some impulses were indicated with abrupt occurrence that dominates the development of movements. The first most significant impulse occurred by the end of the year 2004, the second one at the break of 2005/6. The coincidence of the impulses with earthquake events is discussed., Josef Stemberk and Blahoslav Košťák., and Obsahuje bibliografii
