Ševčíková, Klára
The bachelor thesis deals with the issue of accounting tools in the framework of risks of a manufacturing company with respect to the prudence principle. The aim was to make recommendations for the entity how to better handle such risks in accounting. First of all, a literature search was conducted in the area of the prudence principle, production inputs, production and cash security. In the second part, the accounting methods used by the entity Lef Ltd. were described. Custom recommendations were also described and selected internal accounting guidelines were proposed, available in the attachment of the thesis. The recommendations set out will help the company to keep its accounting records in faithful and honest way.

Reasons and Frequency of Ventilatory Circuit Disconnection in Patients on Artificial Pulmonary Ventilation
Ševčíková, Klára ; Línková, Šárka (advisor) ; Kravcová, Kateřina (referee)
The thesis deals with the reasons for disconnecting the ventilation circuit and the frequency of individual causes. It is part of a broader and more comprehensive study whose common goal is to combat ventilator-associated pneumonia (VAP). The theoretical part of the thesis briefly describes the definition of VAP and its preventive elements. However, it highlights the conflict between manufacturers' recommendations and the results of the latest studies regarding the interval for replacing individual components of the ventilation circuit. Furthermore, it draws attention to the limited and insufficient emphasis placed on this issue both in the theoretical sphere and in clinical practice. The practical part of the thesis presents the results of the conducted observation, whose main objective is to identify the most common cause of ventilation circuit disconnection. The assumption was a high proportion of the frequency of replacing individual circuit components,especiallythe passive heat and moisture exchanger,which was confirmed by the results of the research survey. Another objective was to observe hygiene practices in the care of the ventilation circuit, which had not been fully defined before. Equally important was the establishment of foundations for creatingstandardized procedures and highlighting...

Study of the eclipsing binary systems showing the inclination change
Ševčíková, Klára ; Zasche, Petr (advisor) ; Harmanec, Petr (referee)
The presented thesis is focused on the study of eclipsing binaries showing inclination changes of orbital plane. This orbital precession effect is probably caused by the presence of a third body in the system. Our method is using the study of changing eclipse depth, which allows to independently estimate parameters of the inner system and also to set some constraints on the parameters of third body. In the thesis there were analysed in detail 3 eclipsing binaries using photometric data taken from MACHO and OGLE I-IV catalgoues and from DK154 telescope observations. For the system OGLE-LMC-ECL- 10338 the nodal period was around 115 years, outer body orbits inner binary probably with period <100 days and its mass is <1,38 M⊙. For the system OGLE-LMC-ECL-10413 the nodal period was around 168 years, outer body orbits probably with period <90 days and its mass is <1,50 M⊙. For the system OGLE-LMC-ECL-14394 the nodal period was around 118 years, outer body orbits probably with period <450 days and its mass is <3,12 M⊙. 1

Pain assessment by a registered nurse - possibilities and reality
Ševčíková, Klára ; Otcová, Václava (advisor) ; Zvoníčková, Marie (referee)
The bachelor thesis deals with the nurse's assessment of pain intensity - its possibilities and reality. The theoretical part of the thesis focuses on the overall issue of pain. It includes a brief definition of pain and its treatment options. In particular, it highlights the importance of a correct assessment of intensity, which is one of the key elements of a correct and effective pain management procedure. The practical part presents the results of the research investigation, for which the method of a structured interview and direct covert observation was used. The investigation was conducted only in the Ústřední vojenská nemocnice, therefore these results cannot be applied nationwide. The aim of this paper is to assess the methods to assess pain intensity, which is defined in the standard of the Ústřední vojenská nemocnie. To determine whether these methods are used and, more importantly, whether they lead to effective assessment and thus help to maximize the reduction or complete elimination of pain. The sub-objective was to find a more appropriate method to help ensure this in the event of inappropriate practice. The nurse plays a very important role in this issue and in the whole process of pain intensity assessment, which was confirmed by the results of the research investigation.

Study of dependence of the metal-oxide electron structure on the reactivity of these systems
Ševčíková, Klára
Title: Study of dependence of the metal-oxide electron structure on the reactivity of these systems Author: Klára Ševčíková Supervisor: doc. RNDr. Václav Nehasil, Dr., Department of Surface and Plasma Science Abstract The presented thesis focuses on studying the interaction between rhodium and cerium oxide and its impact on the reactivity. We investigated two different systems, Rh/CeOx and Rh- CeOx, by means of the photoelectron spectroscopy and the temperature programmed reactions. Rh/CeOx stands for rhodium nanoparticles supported by cerium oxide thin film. We show that there is an electronic metal-substrate interaction between rhodium and cerium oxide. The type of the interaction depends on a degree of cerium oxide reduction and it has a tremendous impact on the reactivity of the system. On the other hand, Rh-CeOx represents cerium oxide thin films doped by rhodium. We characterized the properties of the films with various concentration of rhodium. We show that the morphology, chemical composition and reactivity of the samples strongly depend on the concentration of the rhodium dopant.

Wave phenomena around Mars observed by the MAVEN spacecraft
Ševčíková, Klára ; Němec, František (advisor) ; Pitňa, Alexander (referee)
This thesis deals with processing wave data obtained by the LPW instrument onboard the MAVEN satellite spanning a time frame from 10/2014 to 10/2018. We look for an evidence of lightning existence on Mars. We assume that while an electromagnetic pulse originally generated during a lightning stroke would have a form of a vertical intense line in the frequency-time spectrogram, the subsequent dispersion during the propagation through the plasma medium would lead to a formation of a characteristic shape of so-called whistler. We further use the data obtained by the LPW instrument and by the magnetometer MAG to analyze electromagnetic wave environment in the near-Mars space. We study the intensity of electric and magnetic eld uctuations as a function of the position, frequency, solar activity, and Sun-Mars distance. Multicomponent measurements performed by the MAG instrument allow us to carry out a detailed wave analysis of selected events, i.e., to determine the polarity and propagation directions of the observed emissions. We show that all the selected events have common characteristics. 1

Gas molecule interaction with surfaces of oxides including vanadium
Krutel, Jozef ; Nehasil, Václav (advisor) ; Ševčíková, Klára (referee)
The project researches a thin vanadium layer model system. The samples were prepared by vapour-deposition of vanadium on support layer of cerium oxide. The surface composition of samples was monitored by X-ray photoelectron spectroscopy (XPS). The samples were exposed to CO and O2 molecular beams (MB), in order to measure gas adsorption and CO2 production. In the course of reaction measurements by quadrupole mass spectroscopy (QMS) exhibited no signs of oxidative reaction. The XPS spectra show the tendency of vanadium to interact with CO and O2 forming carbide and oxide.

Physical and chemical properties of CeOx/SrTiO3(100) films
Schusser, Jakub ; Veltruská, Kateřina (advisor) ; Ševčíková, Klára (referee)
A study of epitaxial growth of CeOx on SrTiO3(100) surface in CeO2(100)/SrTiO3(100) orientation by reactive vapor deposition in oxygen atmosphere is desirable for widening the current knowledge in the field of ceria-based model catalysts. This work was aimed at determining physical parameters necessary for the growth of CeO2(100) films (substrate temperature, oxygen pressure and deposition rate), atomic structure of the CeO2(100) surface and structure-stoichiometry relation during reversible CeO2↔Ce2O3 transition. Surface science methods were used in order to follow the structural and chemical characteristics of prepared films, such as XPS, XPD, ISS and LEED. The morphology of the prepared films was examined in detail using scanning tunnelling microscope (STM). We also examined the interaction with platinum, which represents the next step towards designing a ceria based catalysts with low noble metal content. Also the redox interaction properties of CeOx and hydrogen were studied.
