Presentation and interpretation of the Žleby chateau after 1945 - a selected example of the management of national cultural property administered by the National Cultural Commission
Roštoková, Nela ; Indrová, Martina (advisor) ; Svoboda, Milan (referee)
This bachelor thesis aims at inquiring into the development of Žleby Chateau after its nationalisation from the house of Trauttmansdorff-Weinsberg, which was based on Edvard Beneš' presidental decrees. Attention is paid to the treatment of this cultural heritage, the operation of National Cultural Commission (NKK) and the administration of Žleby's house contents. Chateau Žleby was chosen by the NKK to be a representative of the Empire and Romanticism styles. In this role, Žleby was to be accompanied by Ratibořice, Kynžvart, Lednice and Hrádek u Nechanic chateaus also evaluated by the NKK. Because of that, the analysis is aditionally aspiring to provide a brief comparison of NKK's work at Žleby and Hrádek u Nechanic. The comparative method supplements archival research which presents the main cornerstone of this thesis. To cover the subject matter also suggests a close collaboration with today's administrations of both sites in question. The documents found within this method provide evidence about the management of the castle by the National Cultural Commission. Specifically, they concern the relocation of various pieces of furniture, but they also address the transportations that were stored at Žleby. The work simultaneously observes the transformation of the castle on two levels - both regional...
Chemical vapor generation of cadmium for analytical atomic spectrometry
Sagapova, Linda ; Kodríková, Barbora ; Svoboda, Milan ; Musil, Stanislav ; Kratzer, Jan
Chemical vapor generation of cadmium volatile compounds was optimized in order to determine trace Cd concentrations by atomic absorption spectrometry (AAS). Several reaction modifiers based on inorganic salts and complexes of CrIII+, CoII+, TiIII+, TiIV+ were tested to improve analytical performance and generation efficiency.

Sagapova, Linda ; Svoboda, Milan ; Matoušek, Tomáš ; Kratzer, Jan
Simple preconcentration step was developed for cadmium determination after chemical vapor generation prior to atomic absorption spectrometric detection. Chemical vapor generation of cadmium was performed in the presence of Cr3+/KCN as modifiers.
Determination of reference parameters for evaluating the strengthening of degraded sandstone masonry of the Cathedral of St. Vit at Prague Castle
Válek, Jan ; Kozlovcev, Petr ; Fialová, Anna ; Slížková, Zuzana ; Kotková, Kristýna ; Svoboda, Milan ; Koudelková, Veronika
Sandstone materials exposed to weather conditions degrade naturally, consequently consolidation of these materials is often required. The aim of this research was to evaluate the impact of four commercials organosilicate consolidants on degraded sandstones, which were used during the neogothic rebuilding of st. Vithus Cathedral at the turn of the 19th to 20th century. The depth of penetration of consolidants into the sandstone porous system and the impact of consolidants on the physical properties of sandstones, namely on the hydrofobicity, water absorption and evaporation, were evaluated primarily. According to the test results, all four consolidants should be suitable for consolidation of sandstones mentioned above even though the results varied slightly between consolidants. For final chose of appropriate consolidant, it is necessary to consider the properties of the treated sandstoned and the technological conditions of the application given by the manufacturer.
Hydride generation study for arsenic speciation analysis with AAS and AFS detection
Svoboda, Milan ; Dědina, Jiří (advisor) ; Spěváčková, Věra (referee) ; Komárek, Josef (referee)
The general aim of this work was a development of methodology and instrumentation for speciation analysis based on the combination of the selective generation of substituted hydrides with atomic absorption or atomic fluorescence spectrometry detection. The first topic of this work was the development of methodology and instrumentation for arsenic speciation analysis based on selective generation of substituted arsines with trapping in the cryogenic trap (U-tube packed with chromosorb) with AAS detection (HG- CT-AAS). The conditions of the selective hydride generation approach as well as working procedure of the cryogenic trap were optimized (appropriate approach for hydride generation, set up of heating program of cryogenic trap, new dryer - cartidge with NaOH, elimination of unspecific absorption, decreasing of the detection limits). The second important part of the work lay in applying of the developed method for arsenic speciation analysis in a homogenized mouse liver tissue. The direct slurry sampling to hydride generator was develop. Moreover the information about oxidation state (iAsIII,V , MAsIII,V a DMAsIII,V ) was obtain. The effect of relevant experimental parameters such as tetrahydroborate concentration, TRIS buffer concentration and time of pre-reduction of the samples by L-cysteine...
Chemical vapor generation of cadmium: detector comparison
Sagapova, Linda ; Štádlerová, Barbora ; Svoboda, Milan ; Kratzer, Jan ; Musil, Stanislav
A chemical vapor generation system was connected to an in-house assembled atomic fluorescence spectrometer (AFS) equipped with a miniature diffusion flame atomizer in order to assess its potential to Cd determination. Subsequently, analytical performance of three spectrometric detectors was compared (AAS, AFS, ICP-MS) with respect to Cd determination after volatile species generation.
Characterization of stone and mortar sampled from Romanesque architectural fragment in archeological site under Prague Castle (CZ)
Slížková, Zuzana ; Frankeová, Dita ; Bauerová, Pavla ; Viani, Alberto ; Kozlovcev, Petr ; Svoboda, Milan
Material characterization of silicite stone and bending earth-lime mortar sampled from the archeological site below the 3rd courtyard of Prague Castle provides data on the chemical and mineralogical composition and microstructure of stone and mortar for the needs of the historic structure conservation.

Chemical vapor generation of cadmium for analytical atomic spectrometry
Sagapova, Linda ; Kodríková, Barbora ; Svoboda, Milan ; Musil, Stanislav ; Kratzer, Jan
Chemical vapor generation of cadmium volatile compounds was optimized, several reaction modifiers based on inorganic salts and complexes of CrIII+, CoII+, TiIII+, TiIV+ were tested. Their use resulted in 4-5 times enhancement in sensitivity, reflected also in corresponding increase of generation efficiency and better repeatability. Generation efficiency was determined from a comparison between sensitivities obtained with chemical vapor generation and conventional solution nebulization, both simultaneously coupled with inductively coupled plasma mass spectrometry. The identity of the generated cadmium compounds was identified.
