Laboratory tests of the degradation of selected sedimentary rocks as a result of their water saturation
Nagyová, Noémi ; Havlíček, Jaroslav (referee) ; Chalmovský, Juraj (advisor)
The work deals with laboratory tests of selected sedimentary rocks and consists of two parts, theoretical and practical. The first part describes the process of "slaking," in which geomaterials disintegrate during repeated cycles of wetting and drying. Than the appearances and types of "slaking," are described as same as the possible main causes of degradation, and the various methods for measuring this phenomenon are described. In the practical part, one-dimensional compressibility tests and grain size analyses were carried on. Compressibility tests were performed in the standard way until the prescribed pressure. In the next loading step, the sample was saturated while maintaining constant pressure, and the volumetric changes were continuously measured. Loading continued when the values were stabilized and for the rest of the test, the sample was kept submerged under the water surface. Within the proposed testing program several tasks were evaluated. One of them wasthe influence of the pressure during saturation, as same as the duration of saturation, the initial porosity number and the sample dimensions. Grain size analyses were performed before and after the compressibility tests. After all this it was possible to determine the structural changes performing by particle disintegration due to the "slaking" effect.

Změny v odvětvových strukturách v České republice
Man, Lukáš
Goal of the bachelor thesis is to compare changes in sectoral structure according to the NACE classification in the Czech Republic. Literary research will include theoretical concept of structural changes and its causes, especially by technological progress and globalisation. Analytical part will analyse structural changes in 2007-2017 according to 3 criteria namely employment, gross value added and average gross salary. Furthermore 3 selected industries will be compared with the Slovak republic.

The Structural Change in the Economy of the United Mexican States
Matzek, Jan ; Sejkora, Jiří (advisor) ; Hasík, Gabriel (referee)
The aim of this paper is to identify and asses the structural change in the economy of the United Mexican States in the period from 1940 until the early 2000s. The data analysis is focused on identifying the trends in the context of Lewis' dual economy model, Kaldor's law, Dutch disease and the natural resources course. Using linear regression, we prove Kaldors' hypothesis on the relation between the growth of the manufacturing sector and the economy as such in the context of Mexico. Furthermore, trends consistent with Lewis' dual economy model are identified. The syndromes of Dutch disease in Mexico and its negative effects on non-mining sectors are described and analyzed.

Structural Change in the Course of Economic Development
Těhle, Václav ; Bajgar, Matej (advisor) ; Glazar, Ondřej (referee)
This thesis strives to identify patterns of structural change while using panel data from 38 countries and 9 economic sectors for the period from 1950 to 2005. Based on mutual correlations between individual countries, two different methods for identifying structural change patterns are designed. The first one assumes constant rate of structural change over time and uses the entire time spans provided in the dataset. Second selects for each economy only certain country-periods with significant structural transformation and looks for similarities in sequencing of these country-periods between individual countries. The classical agriculture-manufacturing pattern is dominant, but significant successful patterns mainly with growing financial and transportation sectors and falling personal and government services are also discovered. In order to provide more complex perspective, proximity maps are drawn with position of each country representing its development path relative to other economies. Lastly, relationship between structural change and economic growth is proven and further examined by listing several stylized facts about the structural transformation, which are evaluated using the provided data.
