Effect of ground limestone addition on properties of cement-slag binder systems
Bílek, Vlastimil ; Másilko, Jiří (referee) ; Opravil, Tomáš (advisor)
This thesis deals with the effect of ground limestone addition on properties of cement-slag binder system. The evolution of compressive and flexural strength of binary and ternary systems (pastes), where 25 % of cement was substituted by one or two admixtures in different ratio, were determined and mutually compared. Granulated blast furnace slag and three different limestones were these admixtures. Two of that limestones were natural and one was prepared by a precipitation. For comparison, mixtures, where ash was added insted of slag, were prepared. The mechanism, by which finely ground limestone participates in hydration process, was studied by conduductometric measurements of systems simulating conditions in fresh pastes, and by TG-DTA method, which was used to determination of added limestone amount which remains in its original form and the amount which participates in the formation of hydration products.

Flame retarders of polymeric materials
Winkler, David ; Poláček, Petr (referee) ; Kučera, František (advisor)
Bachelor thesis focuses on the study of expanded graphite as flame retardant added to low density polyethylene and it´s potential synergistic effect with ammonium polyphosphate. Additive and non-additive dog-bone samples were prepared by compounding and injection. Crystalization, melting point and thermal decomposition of the samples were monitored by TGA and DSC thermal analysis methods. The effect of expanded graphite on the mechanical proporties of the materiál was monitored by a tenssile test. The effect of expanded graphite as a flame retardant and its synergistic effect with ammonium polyphosphate was confirmed by a flame test in the horizontal position of the sample.

Assessing the Synergistic Effects of the Selected Consolidated Entity
Babáčková, Markéta ; Kubovic, Pavel (referee) ; Rajchlová, Jaroslava (advisor)
The thesis focuses on the methods of assessment of synergies established in a consolidated entity. The text includes a definition of a consolidated unit based on theoretical grounds and a draft set of indicators suitable for the analysis of the achievement of synergies. Synergies are monitored through a comparison between the consolidated unit and the mother company made in several selected areas. Results of the analysis of the draft indicators are assessed to determine whether synergies were achieved.

Consolidated Financial Statements
Bursík, Adam ; Miřácký, Vladimír (referee) ; Fedorová, Anna (advisor)
Master’s thesis deals with the consolidation of financial statements and analysis of financial condition of group subjected to consolidated financial statements. Fundamental thesis goal is an assesment of financial position selected group of companies by methods of financial analysis and specialized models. It leads to finding potential weaknesses and creation of proposals leading to eliminate discovered weaknesses and improving the financial situation of group.

Assessing the Synergistic Effects of the Selected Consolidated Entity
Hájková, Jana ; Kubovic, Pavel (referee) ; Rajchlová, Jaroslava (advisor)
This diploma thesis is aimed at assessing the existence of synergistic effects of the selected consolidated entities in the Czech Republic. Using specific financial metrics, the objective of this thesis is to identify the synergistic effects which occur among five consolidated entities operating in the area of property. Measurement and evaluation are performed pursuant to analysis of financial statements as well as qualitative data and are supposed to lead to assessing the existence of synergy in given sphere of national economy.
