Geochemical study of the lacustrine deposits of the extinct Komořany Lake
Valentová, Daniela ; Martínek, Karel (advisor) ; Beneš, Jaromír (referee)
Komořany Lake, regarded as one of the most important sites of the Czechoslovak Quaternary, was situated at the southern foot of the Krušné hory Mountains, northwest from the Starý Most town, between the villages of Souš, Komořany, Ervěnice, Dřínov, Albrechtice, Černice and Dolní Jiřetín. Due to its size, Komořany Lake belonged to the largest bodies of water in the Czechoslovak Republic (25 km2 ) and due to the quantity of organogenic sediments get into the focus of paleoecologists. Gyttji sediments which occupy comparatively thick position in the lake infilling, formed a continuous record from the Last Glacial period to the Subatlantic period and up to now have been processed mainly from the paleoecological point of view. In this work the organogenic sediments are studied from the sedimentary record using modern geochemical methods (TOC/TN and d13C) for the first time in Komořany Lake history. The work was based on profiles (PK-1-C, PK-1-Ch, PK-1-I and PK-1-W) which were taken between 1977-1983 before a complete exploitation of Komořany Lake sediments as a result of coal mining in the Most Basin in the 1980's.

Alluvial stratigraphy of the Líně Formation, Central Bohemian Basins.
Podzimková, Petra ; Martínek, Karel (advisor) ; Opluštil, Stanislav (referee)
Líně Formation is the youngest basin fill unit of the Upper Palaeozoic Central and Western Bohemian basins. Deposits of the Líně Formation were being laid down in Stephanian C time, after an unconformity between Stephanian B and C. The deposits of Líně Formation are continental red beds usually dominated by mudstones with less common appearance of sandstones and conglomerates, originated mostly as fluvial deposits. Lacustrine deposition originated in deposition of less frequented fossiliferous claystones, carbonates of variegated and grey colors, coal occur occasionaly. The study area was at Kladno part of the Kladno- Rakovník Basin, Roudnice part and west half of Mšeno part of Mšeno-Roudnice Basin. Seismic sections were interpreted and correlations of boreholes based on lithology, gama and resistivity ray were made. Scientific borehole K-1 (Klobuky) drilled in 2009 showing 30 m long succession of Klobuky Horizon was described and interpreted too. The interpretations of approximately N-S oriented seismic sections show depressions on the base of Líně Formation. This morphology seems to affect direction and area of sediment deposition at the beginning of Líně Formation sedimentation in the study area. Well-log correlations show main areas of sediment deposition in the west and north of Roudnice part...

Proteolytic Enzymes of Vegetative Forms and Spores of the Bacterium Paenibacillus larvae
Hrabák, Jaroslav ; Martínek, Karel (advisor) ; Kotyza, Jaromír (referee) ; Titěra, Dalibor (referee)
Due to the high resistance of the spores, the bacterium Paenibacillus larvae is the most dangerous bacterial pathogen of the honey bee (Apis mellifera). Thanks to its biological properties and restricted pathogenicity, this bacterium can be used as a model organism to study gram positive sporulating aerobic rods. This work is focused on completing information about secreted proteases of this bacterium and in a study of proteases bound in a spore structure. MYPGP medium was used for the cultivation of P. larvae. In this medium, lysis of the culture was shown after 40 hours of cultivation. The pH of the medium decreased below 6.4 by lysis. The induction of temperate bacteriophage BLA was detected as a causative agent of this lysis. A new sporulation medium called HCBB agar was proposed for the sporulation of P. larvae. In comparison with HCBB agar with MYPGP agar by 31 strains of P. larvae stored in our collection, HCBB agar was evaluated as an appropriate sporulation medium with a median of sporulatin 4.2 ' 106 spores per cm2 in aerobic conditions and 5.65 ' 106 spores per cm2 in aerobic conditions with 10 % CO2. For purification of the secreted proteases, a one-day culture incubated at room temperature was used. Optimal purification of 87/74 kDa and 42/40 kDa proteases was observed after application of this...

Mechanisms driving basin fill architecture in extensional and transtensional alluvial basins.
Hrnková, Magdalena ; Rajchl, Michal (referee) ; Martínek, Karel (advisor)
Sedimentary basins and their fill are subjects of a primary interest within the geological community because of their economic importance, and especially their role as petroleum reservoirs. However, a thorough investigation into the basin fill structures also reveals important information about numerous factors acting upon the region. This thesis is designed to review the mechanisms driving the basin fill architecture of extensional and transtensional alluvial basins. The aim is to describe ways in which tectonics and climate influence the final basin fill, as well as to present concepts used in interpreting the stratigraphic record. The answer of continental sedimentary environments to tectonic forcing is intermittent and abrupt, whereas to the climate change it is more gradual. Tectonics is dominant on the macroscale, whereas on mesoscale both factors have equal roles. Both forcing mechanisms leave distinct traces within the sedimentary record, and a good knowledge of all the possible consequences is essential for a field study of any sedimentary basin.

Climatic, tectonic and provenance record of the Upper Palaeozoic non-marine deposits of the Krkonoše Piedmont Basin
Martínek, Karel ; Opluštil, Stanislav (advisor) ; Nehyba, Slavomír (referee) ; Schneider, Joerg (referee)
Přírodovědecká fakulta University Karlovy v Praze Ústav geologie a paleontologie Charles University in Prague, Faculty of Science Institute of Geology and Palaeontology Klimatický, tektonický a provenienční záznam svrchnopaleozoických kontinentálních sedimentů podkrkonošské pánve Climatic, tectonic and provenance record of the Upper Palaeozoic non-marine deposits of the Krkonoše Piedmont Basin. Mgr. Karel Martínek Autoreferát doktorské disertační práce Summary of the PhD Thesis školitel (supervisor): Doc. RNDr. Stanislav Opluštil, Ph.D. školitel - konzultant (consultant): Prof. RNDr. Jiří Pešek, DrSc. Praha, 2008 Prague, Czech Republic, 2008 Úvod Podkrkonošská pánev je vnitrohorskou pozdně (až post-) variskou strukturou, která pokrývá plochu až 1100 km2 (to zahrnuje i partie překryté mořskými sedimenty svrchnokřídového stáří). Pánev se vytvořila jako součást systému extenzních/transtenzních pánví, ve kterých započala subsidence v pozdních fázích variské orogeneze. Pánev se nachází na severovýchodě českého masívu mezi krkonošsko-jizerským krystalinikem na severu, orlicko-sněžnickým krystalinikem na jihovýchodě a sedimenty české křídové pánve na jihu a jihozápadě (viz obr. 1). Maximální vrty ověřená mocnost vulkanosedimnetární výplně dosahuje v centru pánve téměř 1800 m, ve východní části pánve, na...

Analysis of Services Provided to Citizens' Advisory
Martínek, Karel ; Sedláková, Jaroslava (advisor) ; Stuchlíková, Hedvika (referee)
The aim of the thesis is to do an analyze of services provided by the selected citizen advice and evaluation of the most common problems that clients turned up for help. In the introduction I define the basic theoretical and methodological basis of work. Subsequently, historical aspects will be generalized, which stood at the birth of a new citizen service. In another part I describe the term of counseling, focusing on the typology and principles. I specify the target group and the methodology of work with a client advisor. In conclusion, the theory will focus on the way to guarantee the quality of consulting services in relation to the standards of social services. In the practical part I bring near the role of management consulting citizen selected, the process of obtaining funding sources and ways of organizing work. Then I compare the differences in accounting and reporting against business entities. Further specifications will be made counseling process, with particular emphasis on the expertise of advisors. I do an analyze of services in terms of counseling and also I evaluate the social role of the state. The research part will seek both to confirm or refute the hypotheses set, while a suitable method of analyzing business advisors in dealing with clients in the selected clinic and evaluate the role of preventive counseling in the social phenomena studied. The outcome will be recommendations on how to improve business counseling and counselors themselves.
