A contribution to the problem of the granitoid elevations genesis in the western part of the Černá Voda Hilly land, Žulová batholith

The aim of this paper is to present a hypothetical model of the genesis of granitoid elevations East of the Kobylá nad Vidnavkou village. Two diverse hypotheses have been developed for the elevations’ origin in the literature: (1) glacial erosional sculpting into roche moutonnées, and (2) irregularities of the basal surface of weathering. Applying morphometrical research methods we could show that the elevation elongations strongly correlate with the preferred orientations of the fracture system of the Žulová granite. The studied elevations do not bear any characteristic micro- and/or macro-features of glacial modelling. Granitoid elevations in the studied area are therefore very plausibly built of exposed irregularities of the stripped basal weathering surface (etchplain) and could be denoted as basal knobs.The aim of this paper is to present a hypothetical model of the genesis of granitoid elevations East of the Kobylá nad Vidnavkou village.

Pressure-driven piezoelectric sensors and energy harvesting in biaxially oriented polyethylene terephthalate film

This study reports the possibility of using biaxially oriented polyethylene terephthalate (BOPET) plastic packaging to convert mechanical energy into electrical energy. Electricity is generated due to the piezoelectricity of BOPET. Electricity generation depends on the mechanical deformation of the processing aids (inorganic crystals), which were found and identified by SEM and EDAX analyses as SiO2. BOPET, as an electron source, was assembled and tested as an energy conversion and self-powered mechanical stimuli sensor using potential applications in wearable electronics. When a pressure pulse after pendulum impact with a maximum stress of 926 kPa and an impact velocity of 2.1 m/s was applied, a voltage of 60 V was generated with short-circuit current and charge densities of 15 μAcm−2 and 138 nCm−2, respectively. Due to the orientation and stress-induced crystallization of polymer chains, BOPET films acquire very good mechanical properties, which are not lost during their primary usage as packaging materials and are beneficial for the durability of the sensors. The signals detected using BOPET sensors derived from pendulum impact and sieve analyses were also harvested for up to 80 cycles and up to 40 s with short-circuit voltages of 107 V and 95 V, respectively. In addition to their low price, the advantage of sensors made from BOPET plastic packaging waste lies in their chemical resistance and stability under exposure to oxygen, ultraviolet light, and moisture.Ministerstvo Školství, Mládeže a Tělovýchovy, MŠMT, (RP/CPS/2022/003, RP/CPS/2022/007)Ministry of Education, Youth, and Sports of the Czech Republic [RP/CPS/2022/007, RP/CPS/2022/003

Constraining long-term denudation and faulting history in intraplate regions by multisystem thermochronology: An example of the Sudetic Marginal Fault (Bohemian Massif, central Europe)

The Rychlebské hory Mountain region in the Sudetes (NE Bohemian Massif) provides a natural laboratory for studies of postorogenic landscape evolution. This work reveals both the exhumation history of the region and the paleoactivity along the Sudetic Marginal Fault (SMF) using zircon (U-Th)/He (ZHe), apatite fission track (AFT), and apatite (U-Th)/He (AHe) dating of crystalline basement and postorogenic sedimentary samples. Most significantly, and in direct contradiction of traditional paleogeographic reconstructions, this work has found evidence of a large Cretaceous sea and regional burial (to >6.5 km) of the Carboniferous-Permian basement in the Late Cretaceous (~95–80 Ma). During the burial by sediments of the Bohemian Cretaceous Basin System, the SMF acted as a normal fault as documented by offset ZHe ages across the fault. At 85–70 Ma, the basin was inverted, Cretaceous strata eroded, and basement blocks were exhumed to the near surface at a rate of ~300 m/Ma as evidenced by Late Cretaceous–Paleocene AFT ages and thermal modeling results. There is no appreciable difference in AFT and AHe ages across the fault, suggesting that the SMF acted as a reverse fault during exhumation. In the late Eocene–Oligocene, the basement was locally heated to <70°C by magmatic activity related to opening of the Eger rift system. Neogene or younger thermal activity was not recorded in the thermochronological data, confirming that late Cenozoic uplift and erosion of the basement blocks was limited to less than ∼1.5 km in the study area

Theology of earthquakes

The master thesis deals with importance and meaning of earthquakes as a natural process as well as natural disasters in areas where earthquakes cause heavy damage to lives or properties. The goal of the thesis is to answer the question whether God reveals himself and his divine actions in earthquakes provided that he discloses himself in all his creation in the natural world. A complete list of references on earthquakes in Bible has been compiled and it shows that earthquakes mostly precede or accompany very important events, theophany, and eschatological happening, which always point to God´s glory, power and magnificence. The thesis summarizes historical evolution of theodicy related to earthquakes as natural disasters. There is a paradigm shift from God´s responsibility to responsibility of humankind, in relation to structural sins of the rich against the poor who most suffer during the natural disasters. The thesis offers also synthesizing view on earthquakes as natural process, especially how they reflect God´s invisible characteristics, such as God´s power, glory, magnificence, freedom, wisdom, eternal activity, order, harmony, balance, and beauty

Vybrané metody morfostrukturní analýzy

Morphostructural analysis as a set of several partial methods addresses the explanation of relationship between the geological structure (lithology, structural setting) and the relief within the area. Particular methods are either based on field research or include morphometric methods and methods of remote sensing, which analyse and process interdisciplinary cartographic data as well as digital elevation model (DEM) within the GIS. Field work involves particularly mapping of structural landforms and the fluvial landforms which could be potentially related to neotectonic activity. Moreover, it involves joint and fault analysis compared with results of morpholineament analysis in order to learn their potential causal relationship. Morphometric methods evaluate parameters of relief elements and their relationships. The results of these methods facilitate a selection of model, potentially geodynamic areas, as well as they confirm, complete or specify the results of the field research on the mathematical base

Late Quaternary activity of slow-slip intraplate Mariánské Lázně fault as revealed by trenching and shallow geophysical survey; Bohemian Massif (Czech Republic, central Europe)

The NNW-SSE trending Mariánské Lázně Fault (MLF) zone is situated in the western part of the Bohemian Massif (Czech\nRepublic, central Europe) where it intersects NE-trending Cenozoic Eger rift. The northern segment of the MLF controls the\nmorphologically pronounced mountain front of Krušné hory Mts. and eastern limit of Cenozoic Cheb basin, which is famous for\nearthquake swarms (max. ML=4.6) and CO2 emanation. We performed 2D and 3D geophysical survey (electric resistivity\ntomography, ground penetration radar) and 3D trenching to look for large surface-rupturing prehistoric earthquake responsible\nfor pronounced moutain range front. Seven excavated and six hand-dug trenches revealed a complex geology and deformation\nat the study site probably as a result of right-lateral transpression during Late Quaternary. Two Holocene earthquakes 1150-590\nBC and 780-1000 AD were inferred from 14C dating of faulted Holocene colluvium with corresponding magnitudes Mw=6.7-7.0.\nThe latter one is the youngest documented surface-rupturing event in central Europe.\

Detection agents of diarrhea in children

Summary The detection of diarrhoea origin in children belongs nowadays to a standard examination. The generators cause gastroenteritis. Mainly infants, but also young children suffer from intestine diseases. This disorder causes feverish conditions, vomiting, watery diarrhoea, sickness and inappetence. The aim of the thesis is to prove bacteriological and viral pathogens on the basis of cultivation. There is an outline of the most commonly occurring pathogens in the theoretical part. Bacterial diarrhoea in children is caused by Salmonella, Shigella, Campylobacter, Escherichia coli, Yersiniae and Enterobacteria, whereas viral diarrhoea is caused mostly by the following viruses: Rotavirus, Adenovirus, Astrovirus and Calcivirus. The practical part was performed in the period of October, November, and December 2010 and in January and February 2011 in the Laboma Laboratory, Ltd., now Sylab, Ltd. The thesis aims at children patients till the age of 6. This age was suggested by prof. MUDr. Miloš Velemínský, CSc., dr.h.c., head of the thesis. Child´s swab rectal is used for bacteriological examination, after the transport to the laboratory it is inoculated on a selectively identifying medium and after a 24-hour cultivation, bacteria or virus identification follows. Consequently, enteric bacteria isolation is carried out, through which a pure cultivation is obtained. In order to specify exactly Escherichiae coli, perhaps even its stems, it is necessary to perform serotype to obtain the indicated type and to find out whether it applies to a pathogenic or non-pathogenic bacteria. However, for a virological examination a child´s stool sample is needed. Rotavirus and Adenovirus are detected through the VIKIA r Rota ? Adeno test. This is a qualitative test based on the association of monoclonal antidotes. The test uses the immunological reaction on the testing stripe with help of migration. After 100 randomly chosen samples from children ? patients were processed, it was proven that acute gastroenteritis is mainly of viral origin

Retention of teachers and assistants in kindergarten with special care

This diploma thesis focuses on the retention of teachers and teaching assistants in a specific kindergarten with special care. It searches for the reasons the employees have for staying in their current position and the ones for leaving it. The thesis then continues to research what can be done by this schools management to hold onto quality teachers and teaching assistants. The work observes possible connections of individual aspects of the job with the employees satisfaction and their tendencies to stay in said organization. Among the aspects that influence the employees satisfaction, we can find for example the working conditions, workload, work organization, the ability of professional development, rewards, interpersonal relations in the workplace, communication, the managements leading style or care for employees. In the theoretical part, I've searched through the available literature for connections between job (dis)satisfaction, work behavior patterns and employees turnover. I based my work on literature mostly focusing on psychology and sociology of management, social psychology, social psychology in a workplace, human resources management, management and school management. In the research, I was looking for answers to the research questions, specifically for the links between the..
