Thistorted existence
Kovář, Vojtěch ; Kouba, Petr (advisor) ; Ritter, Martin (referee)
"Thistorted existence" is devoted to ontological issue of frenzy. Based on fundamental ontology it aims to contemplate existential situation of a lunatic, who himself is understood as an existence. Nevertheless, a bit of different existence than Dasein analyzed by Martin Heidegger in the Being and Time. The text strives to gain access to such different existence by an original insight at ontology in general. That gives necessary instruments and ontological notions for understanding the frenzy in its ontological essence. Thus frenzy shows itself as recovery to being and reestablishment of thistorted existence in front of the deal to be.

"Small carbonaceous fossils (SCFs)": state of art
Kovář, Vojtěch ; Fatka, Oldřich (advisor) ; Dašková, Jiřina (referee)
The thesis deals with the problematics of Small Carbonaceous Fossils (SCF). In the first part of the thesis the term SCF is defined and the presentation of the main palynological approaches used for extraction of SCFs follows, together with an explanation of preservation processes of non-biomineralized organic structures in sediments. The explanation of significance for palaeontology and related disciplines is discussed. The main part of the thesis constitutes of descriptions of the individual published SCFs from the late Ediacaran up to the Devonian, together with stratigraphic context and lithology of the published material. The list of taxa, that were possible to identify among obtained SCF material, is included. All the localities of Phanerozoic age are further plotted into paleogeographic maps corresponding with the appropriate periods. The broad scope of SCF's paleogeographic provenance and the possibility of extraction of SCF from a wide spectrum of lithologies, deposited in various sedimentary environments is discussed and the potential of further studies of SCFs is outlined. Key words: organic microfossils and macrofossils, early Paleozoic, taphonomy, palynological preparation methods

SCF in Lower Palaeozoic sediments of the Barrandian area
Kovář, Vojtěch ; Fatka, Oldřich (advisor) ; Brocke, Rainer (referee)
1 Abstract In recent years, the term small carbonaceous fossils (SCFs) has been established to accomodate fragile organic-walled fossils of micro- to mesoscopic size that are usually extracted by means of the 'low-manipulation HF extraction' method. This method has so far only been utilized by several authors and no reports have been published on the usage of the method on samples from the Barrandian area. To test the applicability of the method, samples from the Barrandian area were processed. The samples came from eleven localities representing six stratigraphic units (Paseky Shale, Jince Formation, Letná Formation, Kosov Formation, Daleje Shale and Roblín Member). All the units have been studied before by 'standard' methods of palynological processing. Various previously unreported fossils are described, including wiwaxiid sclerites, putative chaetognath remains and acritarch clusters. Furthermore, it is discovered, that the 'low-manipulation HF extraction' can also be used for extraction of originally calcareous fossils. The pilot study provides a further proof that the 'low-manipulation HF extraction' is a useful tool with the potential to significantly expand our knowledge of fossil assemblages. Key words: Small carbonaceous fossils, Cambrian, Ordovician, Devonian, Barrandian area

On geometry in fundamental ontology
Kovář, Vojtěch ; Kouba, Petr (advisor) ; Nitsche, Martin (referee)
The following text attempts to rethink the challenge of Edmund Husserl in his text On the Origin of Geometry. Interpretation of fundamental ontology developed by Martin Heidegger in Being and Time provides field on which it is possible to try to answer the question of the origin of geometry. It is conceived as a completely unique ontological possibility that nature is able to vouch for an explanation of the geometry.
