Investigation of acid-based properties of mono- and diaza[5]helicenes by non-aqueous capillary electrophoresis and quantum chemical calculations
Šolínová, Veronika ; Štěpánová, Sille ; Jančařík, Andrej ; Klívar, Jiří ; Šámal, Michal ; Stará, Irena G. ; Vacek Chocholoušová, Jana ; Vacek, Jaroslav ; Starý, Ivo ; Kašička, Václav
Non-aqueous capillary electrophoresis (NACE) using methanol (MeOH) as a solvent of the background electrolytes was used to determine the thermodynamic acidity (ionization) constants (pKa) of a series of monoaza[5]helicenes and diaza[5]helicenes protonated to the first degree in MeOH and water. Depending on the number and position of the nitrogen atoms in their molecules, the analyzed aza[5]helicenes were found to be weak to moderate bases with methanolic pKa,MeOH in the range 3.90-8.75 and with aqueous pKa,H2O in the range 3.53-8.28.

Analysis of Financing Research and Development in the Czech Republic
Vacek, Jan ; Hnilica, Jiří (advisor) ; Sieber, Patrik (referee)
The topic of this bachelor Thesis is an Analysis of Financing Research and Development in the Czech Republic. Research and Development (R&D) plays an important role in improving the competitive ability of the Czech Republic, for it constitutes a source for increasing productivity, economic growth and employment. The results of R&D lead to creation of new products and services, which in return increases the quality of life of the Czech citizens. This bachelor thesis focuses on analysis of financing R&D in the Czech Republic. The objective is to find out who finances R&D in the Czech Republic, where do these funds go to, and what they are used on. This thesis also focuses on R&D employees and R&D departments in which they work. The bachelor thesis is concluded by comparison between the R&D data for Czech Republic and other countries form the Europian Union.

Neuwirthová, Elisabeth ; Vacek, Josef (referee) ; Hruzíková, Miroslava (advisor)
The diploma thesis deals with the reconstruction of the railway station Žďárec u Skutče. The station is situated on the track Havlíčkův Brod – Pardubice-Rosice nad Labem. The aim of the reconstruction is to design the platform so that it meets the requirements of mobility-impaired persons. The work deals with track layout adjustments, the reconstruction of both the subgrade and the permanent way and the design of drainage. Also a bill of quantities and costs estimates were reckones.

Comparison of Offering Property Prices in CZ - AU Border Areas
Vacek, Jakub ; Hlavinková, Vítězslava (referee) ; Sopoušek, Milan (advisor)
The aim of this work is to compare family houses prices and analyse real estate markets in the Czech Republic - Austria border areas. The prices of property are compared in two ways: by residental areas and the method of comparing difference index. It has been found, that the property prices in Austria are higher than the property prices in the Czech Republic. As well as, necessary costs associated with a purchase are higher. Nevertheless from the perspective of a possible slump in prices, a purchase of real estate in Austria is a more secure investment.
