Supported Phospholipid Bilayer at the Conductive Interface
Sokolová, Romana ; Kocábová, Jana ; Kolivoška, Viliam ; Gál, M.
The interactions of ethanol and flavonoid compounds with supported phospholipid bilayer\nwere studied by means of electrochemical methods and scanning probe techniques. The\nstability of a 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) phospholipid bilayer\nsupported on different types of conductive substrate was investigated. The relationship\nbetween the method of lipid deposition and the formation of several types of lipid structures\nincluding vesicles, hemimicelles, patches and single bilayers on the interface is discussed.

The Necessity of the Baptism for Salvation in the Light of the Document of ITC
Gál, Miroslav ; Mohelník, Tomáš (advisor) ; Brož, Prokop (referee)
In the Diploma thesis entitled "The Necessity of the Baptism for Salvation in the Light of the Document of ITC" in terms of the document of ITC "The Hope of Salvation for Infants Who Die without Being Baptized" and on the base of the selected parts of the Holy Scripture, magisterial, theological, liturgical texts questions about the necessity of the baptism for salvation of infants and adults are discussed. The baptism is the proper way for all people to be saved. The history of salvation is christocentric; everything is focused on Christ and, vice versa Christ turns to every man, accepts every man. Therefore, one can suppose that for every adult who cannot make an explicit decision for Christ, this Christ acceptation together with its implicit decision is enough for its salvation. On the other side, church prays for those infants who died without being baptized and who could not make neither explicit nor implicit decision for Christ. There are sufficient theological reasons to suppose that these infants will be saved because Christ has accepted also all these children.

The Roman Catholic Church and the Human Rights
Gál, Miroslav ; Ovečka, Libor (advisor) ; Matějek, Marek (referee)
ENGLISH ANNOTATION The Roman Catholic Church and the Human Rights (Bachelor Theses) In this work questions about human rights and freedom are briefly discussed. Two conceptions of the nature of human rights and freedom are characterized. The first one and older one is based on Jewish Christian tradition of creation of mankind. The second one also called antropocentric has its root in Antic age but its development is closely connected with French revolution and independence of the USA. Historical and contemporary relations of Roman Catholic Church to the idea of human rights and freedom form a main part of this bachelor theses. The contrast between Charter of the Rights of Catholics in the Church and encroach on human rights in the Catholic Church is also discussed. Key words: Human Rights; Freedom; Roman Catholic Church; Antropocentric and Jewish Christian Tradition; Encroach on Human Rights

Wireless sports timer
Gál, Marek ; Horák, Karel (referee) ; Petyovský, Petr (advisor)
This work deals with design and realization of universal sport timer and uses wireless communication between individual components. The purposes is to achieve maximum mobility, reliability and simplicity for users. This work doesn‘t deal with sensing elements of measuring system, it only provides examples of their typical usage. The content of this proposal is the primary unit, which will ensure time measurement with 0,01s resolution and the secondary unit, which will track a sensing elements and provide information for processing to primary unit. The design comprises communication method, hardware of all devices and firmware.

Universal measurement interface for digital audio signal
Gál, Marek ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This master’s thesis deals with a modification of existing project which is used as a helpful tool for tracking and measuring digital audio interface I2S. The original design was created by Ing. Martin Stejskal, Polymorphic USB – I2S Interface. Modifications are based on practical one year experience when the device was tested and deals with new requirements for extension. This work describes and justify individual changes of hardware and software part of project.

Reduction and Oxidation of Hydroxyquinolines in Acetonitrile and Dimethylsulfoxide
Sokolová, Romana ; Ramešová, Šárka ; Fiedler, Jan ; Kolivoška, Viliam ; Degano, I. ; Gál, M. ; Szala, M. ; Nycz, J. E.
This study is focused on investigation of oxidation and reduction pathways of selected hydroxyquinoline compounds in nonaqueous solutions. The experimentally obtained reduction potentials are reported to well correlate with calculated values of LUMO energies as well as the obtained oxidation potentials are in a good agreement with theoretical HOMO energies. The cyclic voltammetry, in situ UV/Vis spectroelectrochemistry and in situ IR spectroelectrochemistry confirmed that the oxidation mechanism is complicated. Oxidation unexpectedly proceeds together with protonation of the starting compound. This behaviour was found for all studied compounds, hydroxyquinoline carboxylic acids and also for compounds, where a methyl group is present instead of carboxylic group.

Electrochemistry as a Tool for an Enzyme Characterization
Gál, M. ; Krahulec, J. ; Jiríčková, K. ; Sokolová, Romana ; Híveš, J.
Basic biochemical properties such as Michaelis constant (KM) and turnover number (kcat) of enzyme enteropeptidase was measured by electrochemical impedance spectroscopy. Both values determined by impedance measurements are in good agreement with those obtained by traditional spectroscopic techniques. Therefore one can suppose that electrochemical methods might be successful for such measurements also in the case where usual ones (UV-Vis, fluorescence spectroscopy) are not able to determine these enzyme characteristics.

Electrochemistry of Potential Eu MRI Complexes
Gál, Miroslav ; Sokolová, Romana ; Kielar, P.
Properties of the several potential contrast agents for magnetic resonance imaging (MRI) with Eu(III)/Eu(II) redox couple were investigated by means of the electrochemical methods. Cyclic voltammetry, phase sensitive AC voltammetry, and DC polarography were utilized to elucidate the mechanism of the reduction/oxidation of Eu ion in the presence of these compounds. Moreover, the stability constants of the Eu(II)-MRI agent complexes were also determined. Some suggestions on the chemical structure of the potential contrast agents for MRI are also made.
