The diploma thesis is focused on revision of the type collection of two similar arborescent Carboniferous lycopsids Lepidodendron lycopodioides and Lepidodendron selaginoides. Both species are often misinterpreted in the literature due to their obscure definition by Sternberg. Both species were revised morphometrically, allowing for their redefinition based on morphological characters. The emended diagnosis of both species is provided. Using of existing names of the species was solved in accordance with the International botanical code. Changes in various parametres during ontogenetic development of L. lycopodioides and L. selaginoides were described in detail by using morphometric analysis and both species were redefined. Klíčová slova: Lepidodendron lycopodioides, Lepidodendron selaginoides, pennsylvan, Intra-Sudetic Basin, Radnice Basin, morphometric analysis.

The diploma thesis studies lithofacies and cyclic pattern of about 200 m thick upper part of the Poruba Member (Serpukhovian) in the Karviná area of the Ostrava-Karviná coalfield. The objective of this thesis is to identify laterally persistent cycles from the local ones by the set of cross-sections and to better understand their formation, especially the role of glacio- eustatic sea level changes. Set of cross-sections constructed from boreholes were used for this study. The three genetic cycles were identified in the thesis based on previous studies of Gastaldo et al. (2009). From base to top the cycles are the (i) Max, (ii) Otakar a (iii) Gaebler. Their thickness fluctuates between 19.9 and 109.9 meters. The genetic cycles are bounded, with one exception, by a transgressive erosional surface of important faunal marine bands. From the set of cross-sections and maps of thickness and sand content (%), constructed for individual genetic cycles, it is obvious that the area of maximum thickness corresponds to area of increased content of medium- and coarse-grained sandstone. Maxima of sand content and thicknesses follow NNE-SSW direction, which is in agreement with basin axis. These maxima are interpreted as areas occupied by fluvial channels that are responsible for deposition of coarse- grained...

At Zwartbas, about 10 km west of Vioolsdrif, southern Namibia, the Dwyka succession is composed of tillites and distal fossiliferous dropstone-bearing glacio-marine shales. The completely exposed Dwyka succession is interbedded with thin bentonites, altered distal pyroclastic deposits, which were derived from the magmatic arc at the southern rim of Gondwana. Dropstone-bearing and dropstonefree sequences intercalate with four diamictites, of which the two lowest were certainly recognised as tillites. Four events of deglaciation were proven at Zwartbas and thus consist with correlative deposits in southern Africa. Numerous fossilised fishes, trace fossils, and plant fragments appear frequently within the lower half of the Dwyka succession whereas trace fossils were principally found in the complete succession. Although the environmental determination is quite problematic, the fossil assemblage rather implies proximal, shallow water conditions with temporary restricted oxygenation. The hinterland was covered with considerable vegetation, which points to a moderate climate. Water salinity determinations based on shale geochemistry rectify contrary palaeontological results and point to rather brackish or non-marine conditions in comparison to present-day salinites. Geochemical analyses of the bentonites relate the pyroclastic deposits with acid to intermediate source magmas, as they are known from the magmatic arc in present-day Patagonia. Tectono-magmatic comparisons furthermore emphasise a syn-collision or volcanic-arc situation of the magma source. However, significant cyclicity in the production of the pyroclastic deposits was not observed. Radiometric age determinations of two tuff beds clearly date the onset of glacial activity into the Late Carboniferous.

In vorliegender Arbeit wurde der Einfluss von Propylen-glycol als glucoplastische Verbindung im Präparat "Schaumann Energizer" sowie die Wirkung der den Mineral- und Energiestoffwechsel stabilisierenden, Toxine bindenden Huminsäuren (HS) im "Cellu-Ligno-Karbon-Isolat" in alleiniger Anwendung bzw. in Kombination beider Wirkstoffe beim Hochleistungsmilchrind im peripartalen Zeitraum untersucht. Zur Charakterisierung der Effekte der angewandten Präparate wurden folgende labordiagnostische und hämatologische Parameter bestimmt: Leukozytenzahl, Calcium, anorganisches Phosphat, Natrium, Kalium, Chlorid, Eisen, Glucose, BHB, Gesamtprotein sowie Albumin, Cholesterol, Bilirubin, GLDH, AST, GGT und CK. Des Weiteren wurden klinische Kriterien, wie die 100-Tage-Milchleistung sowie aufgetretene Erkrankungen, wie Mastitiden, Panaritien, Nachgeburtsverhaltungen und Stoffwechselkrankheiten, wie die Gebärparese, das Fettlebersyndrom und die Ketose erfasst. / This paper investigated the effect of propylene glycol as a glycogenic compound in the preparation called "Schaumann Energizer". It was also looked into the effect of humic acids (HA), which stabilize the mineral metabolism and the energy metabolism and bind toxins, on the "Cellu-Ligno-Karbon-Isolat" in single and combinational administration of the active substances to high dairy yielding cows during the peripartal period. The following laboratory diagnostic parameters and haematological parameters were determined in order to characterize the consequences of the two preparations in use: number of leucocytes, calcium,inorganic phophate, sodium, potassium, chloride, iron, glucose, BHB, total protein as well as albumin, cholesterol, bilirubin, GLDH, AST, GGT and CK. Furthermore the following clinical criteria were recorded: 100-day-milk yield, resting time, occurred diseases, e.g. mastitis, paronychia, placental retention and metabolic diseases, such as milk fever, fat liver syndrome and ketosis.

In Its first half this master's thesis describes composite materials with carbon fiber reinforced plastics being the main focus point. An overview of production technologies follows. The major objective of the second part of this master's thesis is to design and manufacture a simplified model of an optical device using prepregs.
