Acid/base properties and reactivity of square planar complexes
DVOŘÁČKOVÁ, Olga
Complexes of platinum and other transition metals are important compounds with many applications including anticancer treatment. This thesis is based on the computational studies dealing with the properties and reactivity of square planar complexes. We showed that the central metal atom acts as a Lewis acid in standard coordination bonds but is able to interact as a Lewis base when being in contact with a Lewis acid. Substitution(s) of the nonleaving ligand(s) enabled a fine-tuning of the reactivity of Pt(II) compounds.

Orgonophosphorus analogues of triphosphate
Šrein, Jakub ; Kubíček, Vojtěch (advisor) ; Štěpnička, Petr (referee)
Two substances were prepared in this work, both with PCPCP structure motif. The motif is similar to ATP molecule, although the oxygen bridges are replaced with methylene groups. Both compounds were characterized by mass spectrometry and NMR spectroscopy. Since bis(methylenephosphonato)phosphinate is soluble in water, four pKa values were determined. Both prepared compounds have potential to serve as chelating ligands. Powered by TCPDF (www.tcpdf.org)

Study on the Reactivity of Extracellular Polysaccharides Produced by Bacteria
Vacková, Barbora ; Smilek, Jiří (referee) ; Kalina, Michal (advisor)
This bachelor thesis deals with the reactivity of bacterial extracellular polysaccharides. The experimental part deals with extracellular polysaccharide FucoPol. Due to the presence of acyl groups, the polymer has an anionic character and can promote interactions with other positively charged substances. In this bachelor thesis interactions of FucoPol with metals were studied. For measuring, an isothermal titration calorimeter was used, and sorption experiments were performed. The main objective of the work was optimization of conditions for measuring interactions between metals and FucoPol. Connection of metal cations to FucoPol matrix were confirmed by titration calorimetry and sorption experiments. The interaction rate was different depending on the metal which was used. Co2+, Pb2+ a Zn2+ ions showed very weak binding, otherwise Cu2+ a Fe3+ ions had high affinity for the studied biopolymer. FucoPol, as a biodegradable biopolymer, can be in the future one of important industrially produced polysaccharides. It could be used for packaging, biofuel production and production of anti-inflammatory and immune-boosting drugs.

Study of the influences that affect the reactivity of a limestone
Sklenářová, Dorothea ; Bureš,, Jaroslav (referee) ; Dvořák, Karel (advisor)
This thesis is a part of grant assignment and focuses on the effect and properties of input material, limestone, on reactivity and speed of decarbonation. The aim of this thesis is to find the effect of chemical composition, petrography, genesis and diagenesis, porosity and microstructure of limestones on reactivity and speed and profile of decarbonation. The experimental part of thesis describes analysis of chosen limestone samples regarding porosity, reactivity by Bischof-Uhde method and process of decarbonation of calcite in term of crystallinity of product.

Reactivity and properties of triphosphate analogues
Šrein, Jakub ; Kubíček, Vojtěch (advisor) ; Vojtíšek, Pavel (referee)
Reactions leading to cyclization on methylene bridges in PCPCP structure motif were investigated. It was found, that these reactions result in number of various isomers. Some of these isomers were characterized by NMR and MS spectroscopy, but none was isolated. Further, acid-base properties of bis(methylenephosphonato)phosphineic acid were investigated. Formation of complexes was studied with lithium(I), calcium(II), copper(II) and zinc(II) cations. Furthermore, interaction between bis(methylenephosphonato)phosphinic acid and ethylenediamine was investigated by NMR and potentiometric titration. The results show formation of H-bond-based adducts.

Physical Fitness of the bodyguards of the Police of the Czech Republic
Mejsnar, Petr ; Heller, Jan (advisor) ; Michalička, Vladimír (referee)
Title of the work: Phycical fitness of personal protectors of the Police of the Czech Republic. Objectives: The main aim of the work was to determine and evaluate the profile of physical fitness of the members of the Close Protection Division, Protective Services of the Police of the Czech Republic. Methods: The work has character of emprical research, its main method was observation. Research sample was composed of 21members (age range 28-55) of the Close Protection Division of Protection Service of the Police of Czech Republic. Within complex testing were used non-invasive methods (anthropomotoric testing, analysis of body composition, anaerobic and aerobic testing, tests for local power and tests of reactivity). An invasive method was also used to test a capillary blood sample to determine the cholesterol level and the postworkout lactate level in blood. Somatic factors were eveluated individualy (antropometry, somatotype, body composition). Conditioning claims were also evaluated (anaerobic, aerobic, lokal power). Within psychophysiological requirements as tested reactivity on acustic and optical signal and as a last there were found out information from health area, blood pressure was measured and compared to level of cholesterol of research sample. Results: The results of observation has...

Reactivity and tolerence to frustration from the perspective of psychology for convicted criminal offenders
Okrouhlická, Kateřina ; Boukalová, Hedvika (advisor) ; Čáp, David (referee)
The thesis deals with reactivity in response to a frustrating situation for convicted offenders. The main issue in the theoretical element is reactivity; or rather the behaviour and manifestation of reactions in the moment when an individual gets into stressful situations, is impeded or blocked in achieving their target. The definition of frustration is an equally important area, which, in the thesis is initially described from the perspective of classic theorists, and then the various ways how we examine and diagnose frustration. The last and equally important chapter consists of the offender's personality, which is defined in the context of the aforementioned frustration and reactivity. The aim of the empirical component is to obtain quantitative data on the most frequent reactions among criminal offenders in the moment before they face the obstacle that is blocking their achievement of goals or satisfaction. The research sample was composed of 69 convicted criminal offenders from remand prisons Pankrác, Hradec Kralové and prison Plzeň. The Picture Rosenzweig frustration method was used to examine the reactivity as a result of frustration. Four hypothesis was determined and only one hypothesis was confirmed. Extragression, outside oriented response, is the most frequently response in comparison...

Reactions to frustration-differences between populations
Vecánová, Jitka ; Čáp, David (advisor) ; Klimeš, Petr (referee)
This bachelor's thesis focuses on reactivity to everyday frustrating situations and it's differences between different groups of people. The thesis is divided in theoretical and practical part. The theoretical part is written as a literary survey and is compiled from various academic sources and studies. It deals with the problem of everyday mental strain, it's definition and the different ways of reaction to it. It also compares reactivity between different groups based on age, gender, socio-cultural and economic status or cultural allegiance. It summarizes the connection between reactivity and personal traits, somatic problems and psychopathology. The practical part of the thesis presents a research proposal which compares reactivity in two groups of people that belong to different cultures using Rosenzweig's Picture Frustration Test. Keywords: Reactivity, daily hassles, daily stress, coping, Picture frustration study 3-5 klíčových slov v angličtině (Případně může být na další stránce abstrakt v jazyce, na jehož studium je student zapsán.)
