The influence of grinding on the limestone properties
Pavlík, Tomáš ; Bednárek, Jan (referee) ; Šiler, Pavel (advisor)
This bachelor thesis deals with dry limestone grinding in the vibratory mill and ball mill. Three different limestone samples were used for milling. Samples were ground in the mills without the addition of surfactants. Several methods of grinding were performed in the vibratory mill. At first, the same weight of limestone samples was ground for different grinding time without any interruption except for one case of grinding with breaks for cooling off the grinding tablet. Another method was grinding of different weights of the same sample. The last one used the same weight of different samples. In the ball mill, sample of one type of limestone was ground for various milling time. The particle size, shape of particles, phase composition and crystallite size were studied for the ground samples. Sieve analysis, laser diffraction analysis, scanning electron microscopy, powder X-ray diffraction analysis and X-ray fluorescence analysis were used to determine these properties. For each mill, the amount of energy consumed for limestone grinding was calculated.

The study of the refractory concrete binding system based on phosphoric acid and aluminous cement
Pavlík, Tomáš ; Švec, Jiří (referee) ; Šiler, Pavel (advisor)
This thesis deals with refractory concrete binding system based on aluminous cement and phosphoric acid. The prepared refractory concretes were fired at 1 000 °C. Various effects on compressive strength of refractory concrete were studied. The influence of aluminous cement content and phosphoric acid content, the influence of various admixtures, the influence of plasticizers and the influence of time and method of sample storage were studied. Simultaneous thermogravimetry and differential thermal analysis of the basic unfired sample were performed. Finally, selected refractory concretes were fired at 110, 200, 400, 600, 800, 900, 1 000 and 1 100 °C. The compressive strength of these samples was measured and powder X ray diffraction analysis was performed. The compressive strength of refractory concretes under intermediate temperatures (800–1 100 °C) was most increased in samples with metakaolin and gray microsilica.

Fundamental Analysis of Selected European Automobile Stock Companies for Creation of Investment Portfolio
Pavlík, Tomáš ; Smolík, Kamil (referee) ; Rejnuš, Oldřich (advisor)
The aim of this master thesis is to create a fundamental analysis of selected European automobile manufacturing companies, which are enlisted in the stock market and are publically traded. Goal of this fundamental analysis is to propose an ideal portfolio which should outperform the average car industry market. All information which are used during this work are publically accessible on the websites of every mentioned company. First part of this work is devoted to the description of methods, which are used through the whole article. Second part is describing selected companies and the reasons of the selection itself. Third part is devoted to the comparison of selected companies. Forth part is describing methods used for verification of the results, methods used for this verification are calculation of the inner value of security and bankruptcy models. The recommendation for the ideal portfolio for the European car industry is created in the last part of this thesis.

Fundamental Share Analysis(Pegas Nonwovens)
Pavlík, Tomáš ; Smolík, Kamil (referee) ; Sojka, Zdeněk (advisor)
The main topic of this bachelor thesis is a fundamental analysis of the shares of the company PEGAS NONWOVENS SA, made by using the publicly accessible information about the company. This thesis also includes theoretical description of the methods which are usable for the fundamental analysis. Then I’ll apply this theoretical knowledge in the practical part of the thesis in order to evaluate the price of shares.

Fish culture facility with a focus on warm water
Pavlík, Tomáš ; Princ, Michal (referee) ; Milerski, Rudolf (advisor)
This bachelor’s thesis deals with the warm water fish culture facilities. It also divides them and represents the manner of the management. The work is divided into two parts. The first part contains research and the second one is dedicated to the project itself. The research describes the most frequent measures that serve to increase the production of thermophilic fishes. The knowledge that has been found is applied in the project. The project describes the extension of the pond management of MO MRS Pohořelice, Z. S., in k. ú. Cvrčovice u Pohořelic.
