Soil salination and natural lignite as a potential remediating agent
Kořínková, Alena ; Sýkorová, Ivana (referee) ; Pekař, Miloslav (advisor)
This bachelor thesis deals with sorption ability of raw and water washed lignite for salt NaCl from water solution. Measurement was carried out in accordance with norm ČSN 11265 Quality of soil – Determination of electric conductivity with some modification (time period, extraction agent). Behaviour of lignite-water-NaCl, soil-water-NaCl and soil-lignite-water-NaCl mixtures was studied by measuring pH and electric conductivity.
Spectrometric Methods for Research of Humic Substances
Enev, Vojtěch ; Maršálek, Roman (referee) ; Sýkorová, Ivana (referee) ; Klučáková, Martina (advisor)
The main aim of doctoral thesis is the study on physicochemical properties of humic substances (HS) by modern instrumental techniques. The subject of the study were HS isolated from South Moravian lignite, South Bohemian peat, forest soil Humic Podzol and finally extract from brown sea algae Ascophyllum nodosum. With respect on determination of structure and reactivity of these unique “biocolloids”, standard samples (Leonardite HA, Elliott Soil HS and Pahokee Peat HS) were also studied. These samples were obtained from International Humic Substances Society (IHSS). All mentioned substances were characterized by elemental analysis (EA), molecular absorption spectroscopy in ultraviolet and visible region (UV/Vis), infrared spectroscopy with Fourier transformation (FTIR), nuclear magnetic resonance spectroscopy of carbon isotope 13C (LS 13C NMR), steady-state and time resolved fluorescence spectroscopy. Obtained fluorescence, UV/Vis and 13C NMR spectra were used for calculation of fluorescence and absorption indexes, values of specific absorbance and structural parameters respectively, which were used for fundamental characterization of these “biocolloidal” compounds. Infrared spectroscopy with Fourier transformation was utilized for the identification of functional groups and structural units of HS. Evaluation of infrared spectra is quiet complicated by overlapping of absorption bands especially in fingerprint region. This problem was overcome by Fourier self-deconvolution (FSD). Steady-state fluorescence spectroscopy was used for deeper characterization of HS with respect to origin, structural units, amount of substituents with electron-donor and electron-acceptor effects, content of reactive functional groups, “molecular” heterogeneity, the degree of humification, etc. Parameters of complexation of samples Elliott Soil with heavy metal ions (Cu2+, Pb2+ and Hg2+) were obtained by using modified Stern-Volmer equation. These ions were chosen purposefully, because the interaction of HS with these ions is one of the fundamental criteria for the assessment of the reactivity of HS. Key part of the whole doctoral thesis is time-resolved fluorescence spectroscopy. It is able to determine the origin of emission of HS by method Time-Resolved Area Normalized Emission Spectra (TRANES). The viscosity of micro medium about excited fluorophores of HS was determined by Time-Resolved Emission Spectra (TRES).
Education by reading and education towards reading
Sýkorová, Ivana ; Vášová, Lidmila (advisor) ; Landová, Hana (referee)
Tématem práce je výchova dětí, mládeže, dospělých a starých lidí k četbě, a také snaha o výchovu těchto skupin pomocí četby. Cílem diplomové práce je zjištění stavu a způsobů čtenářské výchovy v České republice. Jednotlivé způsoby výchovy se od sebe liší v závislosti na věku jedinců, na způsobu výchovy v rodině a ve škole. Dalším faktorem ovlivňujícím čtenářskou výchovu je způsob chování v dospělosti a schopnost začlenění se do sociálních skupin. Praktickou částí diplomové práce jsou dotazníky vytvořené pro žáky 1. - 5. tříd základních škol. K vyhodnocení nejsou použity grafy, vzhledem k tomu, že bylo částečně použito i otevřených otázek, a proto i statistiky jsou zpracovány pouze částečně.
Project of the Center of experimental archeology in Únětice
Pauknerová, Karolína ; Matoušek, Václav (advisor) ; Fridrichová Sýkorová, Ivana (referee)
Based on postprocesualism theories, this master's thesis provides data for setting up the Centre of Experimental Archaeology in Únětice near Prague, designed to pursue an experimental research of Unetice culture agriculture settlement. This project aims to provide space for carrying out archaelogical experiments on the one hand, and to present the results of archaelogical research to public in an innovative way on the other. In addition, it might play an important role in the touristic development of the village.
Trace and minor elements in coal and methods of their investigation
Páchová, Helena ; Opluštil, Stanislav (advisor) ; Sýkorová, Ivana (referee)
The aim of the bachelor thesis is to provide an overview of the minor and trace elements in coal matter and to characterize their origin, distribution and effect on quality of coal in term of its industrial utilization, including potential environmental impacts. The thesis describes main methods currently used when investigating coal geochemistry and mineralogy. The thesis includes overview of the distribution of these elements in the major coal deposits of the Czech Republic.
