Multiple births in Czechia and international perspective
Kratochvílová, Anne-Marie ; Rychtaříková, Jitka (advisor) ; Kalibová, Květa (referee)
Multiple births in Czechia and international perspective Abstract The bachelor thesis deals with the development of multiple births between 1950 and 2019 in the Czech Republic and compares it with the development of multiple births in selected foreign countries, which are France, Japan, Germany, Greece and Sweden. The aim of the bachelor thesis is to analyse the probable causes of the changes in the frequency of multiple births, which has been increasing worldwide especially in the last decades. The bachelor thesis examines the basic characteristics of multiple births and at the same time presents the factors that influence the frequency of multiple births and also looks at the risks associated with multiple births. Keywords: multiple births, multiples, twins, triplets, maternal age, assisted reproduction, trend

Thermal conductivity measurements of materials for the MaMBA project
Sviták, David ; Vališka, Michal (advisor) ; Hrůzová Kratochvílová, Marie (referee)
The content of this work is the measurement of thermal conductivity of materials within the MaMBA project. Single crystalline samples of LaNi$_5$ and PrNi$_5$ were successfully oriented along $a$ and $c$ axis each and disc-shaped polymer samples of PETG and PLA were 3D printed. Thermal conductivity was measured on these samples. The thermal conductivity electrical resistivity and Seebeck coefficient were measured on the intermetallic compounds in the temperature range 2-390K. A magnetoelastic interaction was observed in the PrNi$_5$ samples, contributing to the thermal conductivity. The magnetic character of the PrNi$_5$ compound also contributes to the resistivity at temperatures below 50K. This magnetic contribution was determined for both $a$ and $c$ axis. Finally, the temperature dependence of the thermal conductivity of PETG discs was measured in the temperature range 3-300K. The thermal conductivity of the PLA discs was measured at room temperature.

Practising of verbal forms in the education of Czech for foreigners
Kratochvílová, Marie ; Janovec, Ladislav (advisor) ; Chejnová, Pavla (referee)
The essay deals with the morphological exercises of Czech for foreignes, especially with the conjugatin of verbs. It outlines which exercises could be used for morphology education of Czech as a Foreign Language and it shows which exercises are most beneficial for the initial training of this aspekt od the language and which ones could be used for further training and revision. To learn conjugation in Czech we do not only use exercises such as gap fill, substitution or sentence completion exercises, but we can make use of a lot of language games and activities, which by nature come closer to natural communication. By using concrete exercises, we show how to train the language the best. The theoretical part points out the factors influencing the choice of exercises and shows the most frequent types of exercises to be used for learning a foreign language. The practical part briefly deals with the nouns - categories of numbers, gender, category o f animata / inanimata, because these factors have a major impact on forming the verbs. In the practical part, which is devided into chapters according to the single steps o f learning the verbal forms (Present tense. Past tense. Future tense Conditional, Imperative), we can find a lot of concrete exercises with comments evaluating their use in the education of Czech...

Studium nových silně korelovaných elektronových sloučenin REnTIn3n+2
Bartha, Attila ; Kratochvílová, Marie (advisor) ; Pospíšil, Jiří (referee)
We have studied two different systems; RE2CoIn8 (RE = Pr, Nd, Dy) and CenTIn3n+2 (T = Pd, Pt; n = 2, 3). All compounds were prepared for the first time in the single crystalline form using the self-flux method. X-ray diffraction confirmed the tetragonal Ho2CoGa8 structure type for the RE2CoIn8 compounds and for the new phase Ce2TIn8. The novel phase Ce3PtIn11 adopts the structure of the Ce3PdIn11 compound, which represents a new structure type. Magnetic measurements revealed low anisotropy and the c-axis as the easy axis for all RE2CoIn8 compounds. Pr2CoIn8 is a paramagnet, while Nd2CoIn8 and Dy2CoIn8 order antiferromagnetically. Magnetization and specific heat measurements of Dy2CoIn8 revealed complex magnetic field-temperature phase diagram with various types of magnetic ordering. Specific heat measurements on multiphase Ce-Pd-In system revealed superconducting transition at Tc = 0.69 K arising from Ce2PdIn8 and another magnetic transition from Ce3PdIn11 at ~ 1.7 K. Ce3PdIn11 and Ce3PtIn11 compounds reveal two, probably magnetic transitions at T1 = 1.6 K, T2 = 1.45 K and T1 = 2.1 K and T2 = 2.0 K, respectively. Specific heat data qualifies both materials as heavy fermion compounds with γ = 290 mJ.mol-1 Ce K-2 and γ = 300 mJ.mol-1 Ce K-2 respectively.

Authorship between ethics, law and technology
Kratochvílová, Marie ; Pinc, Zdeněk (advisor) ; Sokol, Jan (referee) ; Benyovszky, Ladislav (referee)
AUTHORSHIP BETWEEN ETHICS, LAW AND TECHNOLOGY In the present thesis, I focus on the relation between the concept of authorship and the development of new technologies, linked to the transformation of the ethical paradigm. I focus on the author as a person, on the ethical aspect of authorship and its protection within society, on traditional rules of polite and honest behaviour which are intertwined with the codification of legal protection of the rights of the author. The discussion takes place on two levels which have co-existed since authorship came into existence: one of them is the protection of the rights of authors, including the introduction of copyright, the other is the attempt to infringe on these rights in order to allow for the free sharing of cultural property as well as of the results of scientific work. In the Introduction, I provide an overview of the transformation of the relation between the author and society, between authorship and its legal basis. I focus mainly on its philosophical aspects, reflecting the state of technological development and the situation in society. I follow the differentiation between divine inspiration (claim for the truth) and the concept of authorship (claim for a salary), which first came into prominence toward the end of the archaic period. I...

Studium magnetických a termodynamických vlastností ternárních sloučenin se silně korelovanými 4f elektrony.
Kratochvílová, Marie
We have studied two different systems of compounds, YPd2Al3 and CenTmIn3n+2m. Polycrystalline YPd2Al3, a new member of the REPd2Al3 system, was prepared by arc melting. The X-ray diffraction confirmed that YPd2Al3 crystallizes in the hexagonal PrNi2Al3-type structure as the other REPd2Al3 compounds. Magnetization, AC susceptibility, specific heat and resistivity measurements revealed superconductivity below Ts ≈ 2.2 K. The second part of the work was focused on studies of Ce2PdIn8 and Pd-doped CenRhIn3n+2. Single crystals of Ce2Rh1-xPdxIn8 with x = 0, 0.10, 0.15, 0.30, 0.45, 0.85, 1 and CeRh1-xPdxIn5 with x = 0, 0.1, 0.25 were prepared by solution growth method. The quality of crystals was confirmed by microprobe analysis and X-ray diffraction. The effect of Pd doping on magnetism of CenRh1-xPdxIn3n+2 was studied by specific heat, magnetization and resistivity measurements. The Pd doping gradually suppresses the Néel temperature in both systems, however the effect is stronger in Ce2Rh1-xPdxIn8. Temperature dependence of resistivity of CeRh0.75Pd0.25In5 was studied in pressure up to 2.2 GPa. Similar to CeRhIn5, the antiferromagnetism is gradually suppressed by the applied pressure, while superconductivity is induced and coexists with antiferromagnetism.

Magnetic study of layered tetragonal compounds based on rare earths and uranium
Bartha, Attila ; Hrůzová Kratochvílová, Marie (advisor)
We have studied the interplay between the layered crystal structure and the 5f magnetism in uranium-based tetragonal compounds UnTIn3n+2. Sin- gle crystals of U2RhIn8, URhIn5 and UIn3 were prepared by In self-flux method. The novel U2RhIn8 compound adopts the Ho2CoGa8-type struc- ture with lattice parameters a = 4.6056(6) ˚A and c = 11.9911(15) ˚A. The behavior of U2RhIn8 strongly resembles that of related URhIn5 and UIn3 with respect to magnetization, specific heat and electrical resistivity except for magnetocrystalline anisotropy developing on stacking composition in the series UIn3 vs. U2RhIn8 and URhIn5. U2RhIn8 orders antiferromagnetically below TN = 117 K and exhibits slightly enhanced Sommerfeld coefficient γ = 47 mJ·mol−1 ·K−2 . TN increases with increasing c/a ratio in contrast to the behavior of their CenTIn3n+2 counterparts. Magnetic field leaves the value of the Néel temperature of URhIn5 and U2RhIn8 unaffected up to 9 T. On the other hand, TN increases with applied hydrostatic pressure up to 3.2 GPa with the ∂TN/∂p coefficient resembling URhIn5 and UIn3. Ther- mal expansion of U2RhIn8 reveals a hysteretic behavior of the antiferromag- netic transition pointing to its 1st -order character. The magnetic structure of URhIn5 obtained from neutron diffraction propagates with k = (1 /2, 1 /2, 1 /2) and the...
