Labio, a.s. – research study of gas chromatograph enhancement
Divoký, Martin
This project aimed at testing and development of a UV gas chromatograph Labio G11. A spectrometer from the chromatograph was modified in order to increase nitrogen gas flow in the device and speed at which the inner of the spectrometer is filled with nitrogen (that doesn’t absorb in UV). This allowed decreasing startup time of the spectrometer. Additionally, sensitivity of the spectrometer in region below 150 nm was tested and ways to increase this sensitivity were proposed.

Cycle route between Havířov and Hrabová
Kocurek, Ondřej ; Novák, Martin (referee) ; Všetečka, Martin (advisor)
This Bachelor thesis deals with the design of a cycle route between the town of Havířov and Hrabová, a district in the city of Ostrava. Current cycle routes in this area are routed as part of the roads II/478 and II/ 473 along which a heavy traffic volume flows. Therefore, the usage of these routes is unsuitable. This arrangement also diminishes the recreational function of the cycle routes. The newly suggested route guarantees a safer connection between Havířov and Hrabová, where it joins an existing cycle rout, no.6064. The cycle path follows the course of the Lučina river where a ring road for pedestrians, cyclists and inline skaters is thereby created. Furthermore it will use purpose-built and local roads with a low volume of traffic. The plan is divided into four parts and each is assessed separately. The cycle rout is designed in accordance with the applicable standards and regulations.

Mobilization of neutral compounds by inorganic and small organic ions in capillary electrophoresis
Křížek, T. ; Martínková, E. ; Kubíčková, A. ; Hladílková, Jana ; Coufal, P. ; Heyda, J. ; Jungwirth, Pavel
The present study shows that neutral low-molecular-mass compounds that are presumed to possess zero electrophoretic mobility and are thus used as markers of electroosmotic flow in capillary electrophoresis can acquire electrophoretic mobility due to ion-specific interactions with constituents of background electrolyte. Therefore, these neutral markers, such as thiourea or dimethyl sulfoxide, can be separated in electric field and their migration order can vary depending on background electrolyte composition. This observation has some important implications for analytical and physico-chemical measurements using capillary electrophoresis because the choice of the marker-background electrolyte combination can influence the results of the measurement.

Bulk Evaluation of User-Defined Functions in XQuery
Bednárek, David ; Král, Jaroslav (advisor) ; Kuznetsov, Sergey (referee) ; Krátký, Michal (referee)
XPath queries are usually translated into an algebra that combines traditional relational operators and XML-speciffic ones. In particular, FLWOR loops are represented using nest, unnest, join, and similar operators and their original nested-loop nature disappears, creating an opportunity for bulk evaluation and join reordering. In XQuery, two additional issues shall be handled - tree construction and the presence of user-deffined functions. The recursive nature of functions pushes the problem outside of the range of relational algebra. This thesis presents a novel evaluation framework based on an expanding network of relational operators, called R-program. In this environment, functions are evaluated in bulk instead of evaluating each call separately. Besides obvious advantages of bulk evaluation, R-programs also allow rearrangement of data flow across function boundaries. A set of program transformations employing these capabilities is described; together with rule-based static interprocedural analysis algorithms used to determine the applicability of the transformations.

The Influence of Shoulder Protraction Correction to the Postural Stability
Zachová, Marie ; Otáhal, Stanislav (referee) ; Lopot, František (advisor)
The Influence of Shoulder Protraction Correction to the Postural Stability Abstract This work is focused on postural stability from the view of physiotherapy and biomechanics. The basic theme was to find out to what degree the correction of shoulder protraction will influence the postural stabilization of modified tip-toe standing position. For this purpose was set up a special methodic for measuring and data evaluation. Within filling the project of this work, there was suggested and performed a special method of measuring on 2 Kistler force plates, when 1 of the plates was fixed in ½ m. height from the ground on a special inclined construction. The angle of the plate with the ground contained 60ž. There were 5 probands involved in the experiment (aged 20-30 years, having shoulder protraction without any pathology of these joints). The probands were separated up to 3 groups in compliance with the degree of shoulder protraction. Each proband was measured before and after the therapy on the 2 Kistler plates in an oblique tip-toe stand with one upper extremity leaned against the plate in 60ž abduction. The Kistler plates were placed under the lower extremities and the one upper extremity and the measuring took 30 sec. on the left and 30 sec. on the right upper extremity. The therapy took 30 minutes and it was...

Legal regulation of pension insurance in the Czech Republic and the Polish Republic
Mitrega, Jan ; Zemanová, Jana (advisor) ; Vysokajová, Margerita (referee)
Legal regulation of pension insurance in the Czech Republic and the Polish The goal of this diploma theses is to point out the legal regulation of pension insurance in the Czech republic and the Republic of Poland putting emphasis on regulation of different types of pension. The thesis consists of four chapters. The first chapter analyzes the historical evolution of pensions and the pension insurance. It comprises three periods. The first period ends at the time of the World War I., the second one lasts until the end of the forties of the 20th century and the last one ends in the late 20th century. This chapter outlines the history evolution separately for both of the states. The second chapter is a base of this paper. It examines contemporary legal regulation of pension insurance in the Czech republic. At the beginning of the chapter, there are explained fundamental principles of the Czech pension insurance system and also essential terms. The following part of the second chapter explores legal regulation of allowances including old-age pension, invalidity pension, widow's and widower's pension and orphan's annuity. In the connection with every single mentioned matter, it puts emphasis on the following: the conditions under which a claim to a pension can be acquired, modified or extincted and the...

The Identification and the Origin of the Gemstones Adorning the Insignia of the Charles University in Prague , the Faculty of Science
Petrová, Zdeňka ; Hanusová, Irena (referee) ; Goliáš, Viktor (advisor)
The issue of a sceptre for the newly founded Faculty of Science was first discussed on the meeting of Faculty professors on the 25th November 1921, more than a year after the separation of the Faculty of Science from the Faculty of Arts. The commission elected from among the professors proposed a motion that the new Faculty sceptre should resemble the sceptre of the parental Faculty of Arts. Through a mediation of the Ministry of Education and National Enlightment the design of the new sceptre was ordered from the Academy of Arts, Architecture and Design and it was elaborated by prof. Jaroslav Horejc. However, in January 1923, his design was rejected, because it didn't meet the requirements of the professors' conservative approach. When prof. Horejc refused to make a modified copy of the sceptre of the Faculty of Arts, the professors addressed Tengler, the goldsmith who had made the sceptres of other faculties and of the rector in previous years. Alois Tengler was willing to make a modified copy of the sceptre of Faculty of Arts, but he also proposed a new design (with estimated price of 20 000 K), which the professors found more suitable and subsequently this design was adopted. Tengler committed himself to manufacture the sceptre by the 15th November 1924 and to incorporate any additional design...

Occurrence of Common Kingfisher on the Blanice river and the effect of modification of the riverbed on its ecotope
KAŠTÁNKOVÁ, Veronika
This bachelor thesis deals with the monitoring of kingfisher presence in the natural as well as modified biotope in certain sector of the Blanice river´s flow. The chosen section is a part of the Blanice river beginning before Bavorov village by ?U Skuhrů? locality and ending under the Husinecká přehrada dam. This work focuses on floodings, antiflooding modification and its influence on kingfisher biotope. Processing this bachelor thesis, it was found out that 5,6 % of the left and 5,1 % of the right bank of the focused part of the river show features of antropogenic adaptation. It was also found out, that 30 % of the chosen part of the river have appropriate conditions for kingfisher nesting. In these parts of the river, there were found altogether 25 unoccupied remainders of old nests and 3 occupied nests. The most suitable locality for kingfisher nesting from all monitored areas is in the natural part between the villages of Blanice and Strunkovice nad Blanicí. One of the occupied nests was found in anthropogenicly modified part of the river flow in the village of Husinec. It was 50 metres far from the river in the steep hillside. The banks of the river in this area were strengthened after the floodings by stone from quarries and the stream bed was artificially straightened.

Valuation of Limited Liability Company
Pätnická, Lucie ; Brabenec, Tomáš (advisor) ; Dvořák, Jaroslav (referee)
The main goal of the thesis is to find the market value of the limited liability company as of the date 31. 12. 2014. Companys business activities are divided into four divisions : accumulators and batteries, measuring equipment, security systems and solar systems. Financial analysis is conducted for the enterprise as a whole, strategic analysis is due to the different sectors in which the individual divisions operate handled separately for each division. Based on the results of the financial and strategic analysis, the valuation method of the discounted cash flow variant entity was used to determinate the estimated market value. The prognosis of the value drivers and financial plan are also parts of this thesis.
