Jaques, Victory Armida Janine ; Holcová, Katarína (advisor) ; Caruso, Francesco (referee) ; Oszczypko-Ciowes, Marta (referee)
This PhD thesis is a commentary of four studies published and a fifth study submitted in peer reviewed and impacted scientific journals. Three studies are methodological work for the preparation of painted micro-samples to improve the measurements accuracy, the samples visualisation, and the combination of measurements methods. The two other papers focus on the fossil assemblages determination and comparison between reference historical areas and original paintings. This work is divided into three main parts, namely the introduction, the methods, and the calcareous nannofossils assemblages. In the introduction, detailed explanations are given about the paintings, historical materials, trade roads, what are nannofossils, how and why to use them. In the methods section, developed preparatory methodologies are summarised, and the most important results are explained. In the third part, the nannofossils assemblages, the differences between the assemblages from different areas in Europe compared to original paintings are explained and correlated to the literature. The impact of the preparatory methods on the results is discussed, and a conclusion is drawn from it in the context of painted artefacts in the Cultural Heritage field are unique, and so are the micro-samples from them. To extract most...

Chemical variability of garnets from the České středohoří Mountains and characterization of their mineral inclusions
Píšová, Barbora ; Skála, Roman (advisor) ; Kotková, Jana (referee)
The samples of garnets used in this study come from clastic sediments from the drillcores Tř-1 and T-31, selected localities of the České středohoří Mountains and garnet-bearing ultramafic rocks sampled by the drillcore T-7. The contents of the major and some minor elements were determined by an electron probe microanalyzer. The garnets from the sediments were divided into 3 groups according to the contents of the end-members: 1) pyrope-, 2) almandine - pyrope- and 3) grosular - almandine-rich. Garnets from the drillcore T-7 were classified according to individual rock types in which they occurred: lherzolite, hazburgite, pyroxenite, eclogite and granulite. Chemical analyzes of garnets displayed the presence of positive correlations Cr vs. Ca vs. Ti Mn in pyrope grains. The contents of trace elements in garnets were studied by an LA-ICP-MS. After normalization to the CI-reservoir, garnets most often show lherzolite profiles of rare earth elements. Garnets of intense red and purple colors show slightly sinusoidal REE profiles. Inclusions enclosed in garnets were studied by a scanning electron microscope. If their dimensions allowed, the major and minor elements were determined by electron microanalysis for inclusions. Inclusions of amphiboles in association with spinel group minerals, carbonates and...

Effect of seed treatment on the germination of different provenances of Dodonaea angustifolia; a recommendation for degraded land restoration through direct seeding
Petrovičová, Lucia
In Jara Jinesa nursery site in Ethiopia near Awassa city an experiment on germination rates of Dodonaea angustifolia was realized in 2015. To examine this rate, three different provenaces were evaluated for four different seed treatment methods and compared with control sample of untreated seeds. Hot water treatment at both time intervals prove significantly positive effect on seed germination. After this treatment seeds germination rate reached from 70 to 100 %. The positive effect of seeds soaking in cold water has not been recorded, in some cases even reduced germination over any untreated seed. Within 3 to 6 days of sowing, especially in warm water treated seeds, the number of germinated seeds increases steeply. The impact of provenance is evident especially in the various time span optimization, since each provenance is adapted to specific environmental conditions. Treating seeds with warm water before sowing increased the uniformity of seedlings, thereby increased the quality of seed production without significant technological equipment and financial costs

Following old master drawings within the collections of selected Czech collectors
Babická, Lenka ; Zlatohlávek, Martin (advisor) ; Jarošová, Markéta (referee)
Following old master drawings within the collections of selected Czech collectors Abstract This thesis is a contribution to the history of collecting in Bohemia. It deals with the collecting of drawings and tracks them within the selected collections and collectors. It focuses primarily on the old master drawings, defined as works from the 16th to the 18th century. Within the issue of collecting the attention is, even when studying specific personalities, often paid to the picture galleries rather than the print collections. Due to its fragile nature, drawing tends to fit into the background and, if it does not form the main part of the collection, is not reflected. Many of the collections and collectors have come to attention lately, but many still await their appreciation and introduction into new contexts. Keywords Collecting, collector, drawing, Old Master Drawings, Bohemia, provenance, Prokop Toman, Rudolf Kuchynka, Vincenc Kramář, Jan Krčmář, Frits Lugt

Vliv provenience na růst semenáčků douglasky tisolisté
Juračka, Michal
The aim of the study was to evaluate the effect of different provenance on the growth of Douglas fir on uncovered mineral soil. There were tested 14 provenances from Canada and 2 from Czech Republic. There were monitoring bare-root seedlings in forest nursery Cetkovice. There were evaluated 100 seedlings from each provenance. In this study is also comparison with one-year and two-year seedlings which were measured in 2011 and 2012. In this study are mentioned basic characteristics about forest nursery Cetkovice where was cultivated of planting stock. The provenance SHAWATUM C var. menziesii was assessed to be the best of three-year seedlings, on the other hand the worst was the provenance HOSPITAL CR var. glauca.

Determination of geological provenance by cathodoluminescence spectroscopy of apatites and carbonates
Pánik, Róbert ; Matějka, Dobroslav (advisor) ; Ježek, Josef (referee) ; Skála, Roman (referee)
This work presents new method for determination of geological provenance based on the statistical analysis of cathodoluminescence spectra of marbles and carbonate rocks from various localities in the Bohemian Massif. Analysis is based on the combination of data from seven different measures of spectral similarity and provides results that are more robust than those obtained by approach based only on a single measure of similarity. These results may be further improved by employing meta-analysis that evaluates behaviour of spectra during the individual steps of analysis. Analysis was performed on the original cathodoluminescence spectra, as well as on the residual spectra in which relative variability was amplified by the subtraction of Gaussian trend present in all spectra of carbonates. By combining results from analysis and meta-analysis of both original and residual spectra it was possible to almost unambiguously determine provenance of samples from all studied localities. Agglomerative hierarchical clustering was employed as a supplementary method for classification of spectra. Out of 72 different methods for clustering, one was selected for both original and residual data based on the number of correctly classified spectra. Second part of this work presents analysis of cathodoluminescence...

Ravennate Marble Trade in the Late Antiquity: Material from the San Severo Complex
Tůmová, Helena ; Ondřejová, Iva (advisor) ; Bouzek, Jan (referee) ; Cantini, Federico (referee)
This thesis aims to study the commercial mechanism of Ravenna in the Late Antiquity from the point of view of the amount, type and provenance of the imported stone artefacts (fragments of architectural decoration, revetments slabs, opus sectile, sarcophagi), based on the study of archaeological material from the site of the basilica and the monastery of San Severo in Classe (Ravenna). Ravenna represented an important administrative and cultural center in the 5th and 6th century, connecting western and eastern artistic influences and focusing herself on trade and production. Determination of the stone artefacts from the San Severo locality was principally based on the archaeometric methods and on the combination of archaeologic and geologic approach as well. Specific archaeometric methods (macroscopic, geochemical and mineralogical-petrographic analyses) together with a quantitative evaluation were applied. Many scientific works, dedicated till this time to the art history of late antique Ravenna and dealing also the argument of ravennate "marbles" presumed the prevailing provenance from Proconnesos and usual commercial relations between Ravenna and Constantinople as well. Constantinople played a role of a mediator of oriental localities and Ravenna. The hypothesis concerning the provenance of the...

Growth and environmental effects of Grand fir cultivation in conditions of the Czech republic
Fulín, Martin ; Podrázský, Vilém (advisor) ; Antonín, Antonín (referee)
Grand fir (Abies grandis /Douglas ex D. Don/ Lindl.) is a species with potential benefits for the implementation of many functions in forest management: namely the function of production, soil improvement, stabilization and landscaping. It was introduced to the Czech Republic, as well as to other European countries, since the first half of the 19th century, mainly by aristocratic families. First plantings were performed in the parks, but gradually also in the forest stands. Another wave of interest in this tree species was associated with the decline of the domestic silver fir (Abies alba Mill.). It was to some extent substitute, for this period comes the greatest number of plantations in the country. The aim of this thesis is, therefore, monitoring of growth and production of the grand fir, but also the evaluation of the effects on the basic characteristics of the soil chemistry, nutrient dynamics and possible degradation effect on forest lands. Research areas were mainly located in the University Forest Enterprise Kostelec nad Černými lesy, but also in other places such as Hrubá Skála at Turnov, forests owned by Kinský at Žďár nad Sázavou and Kynšperk nad Ohří. Monitoring was carried out on already established and monitored middle-aged permanent plots (35 to 55 years), which were assessed at mensurational parameters (position, height, diameter at breast height, ratio of the green crown), in further the quantity and quality of forest floor and upper mineral soil components was studied. This work also contains the measurements of the provenance plot of Forestry and Game Management Research Institute. The results show that the grand fir is a productive tree species that exceeds the stock of domestic conifer tree species and its intensive growth is comparable with Douglas fir. From the perspective of provenance trials is crucial the correct choice of provenance, which achieves better yields and quality of wood. Best provenances come from the island Vancouver and the coast of Washington state. At the soil analysis reaching grand fir better values in comparison with Norway spruce and got it closer to the values of broad-leaved tree species. Thus it can be said that grand fir represents important soil-improving and stabilization tree species.
