The significance of magnesium for human health
Škeřík, Jan ; Hrstka, Miroslav (referee) ; Vránová, Dana (advisor)
Aim of this bachelor thesis was to compare different forms of magnesium. The characteristics and history of magnesium was briefly described at the beginning of the theoretical part. The following chapters explain the importance of magnesium in the body, hypomagnesemia, hypermagnesemia. Another section describes magnesium effect on various diseases, increased intake of magnesium and magnesium metabolism. The ninth and tenth chapter describes the effects of nicotine and alcohol on the metabolism of magnesium and magnesium content in drinking and mineral water. Conclusion of the theoretical part is dedicated to the description of the analytical methods of dosage forms. At the heart of the practical part was using several commonly used methods to determine best magnesium addition. It was the method of determination of the mass uniformity, determining magnesium contents in the tablet, the determination of disintegration, dissolution determination and hardness determination.

High bit rate LTE mobile system
Ohera, Vlastimil ; Kejík, Petr (referee) ; Hanus, Stanislav (advisor)
Aim of thesis was to acquaint with architecture and process of signal in systems using broadband LTE wireless technology. Thesis in detail is described physical layer of system. Next there is described comparison of LTE and WiMAX and table with all present systems. Thesis also is contained information about tested LTE system in real traffic. Next aim was created simulation of LTE system in downlink and uplink. Interface was created for easier configuration of each characteristics of transfer and type of interference of useful signal. This interface is contained control of whole simulation and presentation of measured values. Measured data were processed into graphs, which show dependence of error rate BER on C/N of useful and interference signal.

Humic substances as transport medium for plant nutrition
Vlková, Markéta ; Solná, Irena (referee) ; Klučáková, Martina (advisor)
This bachelor thesis treats about humic matters and their application in agriculture by means of hydrogels transport medium. It studies progressive releasing of substances, which could be used as more common nutrition for plants, prepared from superabsorbent polymers. Research was implemented in collaboration with industrial partners. The substances are synthetically made of sodium Lignohumate and mixture of industrial fertilizer called NPK. Released substances were characterized by using some methods. First, there were measured qualities, which didn’t specify released compounds, like swelling, conductivity, pH and absorption of hydrogels with different wavelengths. More details came with methods ICP-OES and ion chromatography. Hydrogels which contained both mixtures of matters written up, were studied in water solution for 5 weeks and every week all characterization were measured. From the results we can see that both of the mixtures decrease ability of hydrogel’s swelling, mainly NPK. Measuring of absorption showed that the most of the substances released from sodium Lignohumate were from hydrogels without NPK. By other measuring, we noticed realizing of potassium and phosphorus elements. The most of them were from hydrogels containing NPK. By measuring ion chromatography, we found chloride, phosphoric, sulfuric and nitric ions in solution.

Superabsorbents with controlled release of nutrients
Závodská, Petra ; Kratochvílová, Romana (referee) ; Klučáková, Martina (advisor)
This thesis is focused on the study of superabsorbent polymers and their ability of control release of nutrients. These polymers can absorb huge amount of water, up to hundredth times more than the original weight is. In combination with nutrients, especially nitrogen, phosphorus, potassium and lignohumate, they make effective fertilizer. Due to this fact, the possibility of use in agriculture is increasing. Therefore, experiments that are researching the ability of containing the water were performed, the swelling capacity was measured. Experiments that are related to control release of nutrients were performed next. Therefore, this thesis is focused on the study of superabsorbent polymer characterisation, that can be used in agriculture.

The issue of the concept of criminal custody
Beňák, Ondrej ; Hořák, Jaromír (advisor) ; Bohuslav, Lukáš (referee)
The thesis deals with the issues of pre-trial detention in the criminal procedure of the Czech Republic. It comprises and compares opinions voiced by various scholars, high courts and myself. The thesis also includes a section about the rules of pre-trial detention in the American federal criminal procedure and compares it with the Czech system. The first part of the thesis is the Introduction, in which the goals of the thesis are set out. The second part is the main part of the thesis and it is divided into five chapters. The first chapter consists of a general description of pre-trial detention in the Czech Republic and the principles that govern it. The second part is called Formal Rules of Pre-Trial Detention, and it deals with the issues of competence, court procedure and decision-making. The third chapter is where the focus point of the thesis lies, as it investigates the conditions of ordering a pre-trial detention of a person and adresses the numerous problems that arise in this area. The fourth chapter describes the conditions for pre-trial release of an accused person, including the legislative changes recetly made in this area. The fifth chapter explores the American federal criminal procedure and compares it with the Czech criminal procedure. It also includes American scholars'...

Multidimensional characterization of polyelectrolytes and interpolyelectrolyte complexes in aqueous solutions
Murmiliuk, Anastasiia ; Štěpánek, Miroslav (advisor) ; Šachl, Radek (referee) ; Hoffmann, Ingo (referee)
Multidimensional characterization of polyelectrolytes and interpolyelectrolyte complexes in aqueous solutions Abstract: This PhD thesis is dedicated to the study of polyelectrolytes and their self-assembly in aqueous solutions. The morphology and ionization state of individual polymer chains were investigated as well as their co-assembly with oppositely charged species. First, the charge regulation of short and long weak polyelectrolytes in aqueous solution was investigated to deeper understand their pH-responsive properties. The changes of ionization degree and charge of oligopeptides composed of 5 amino acids with acid side-chains and 5 with basic side chains were followed upon varying the pH in order to reveal the effect of interactions between the like-charged and oppositely charged groups. It was shown that intra-molecular electrostatic interactions and conformational flexibility caused the suppression of the total charge and enhancement of ionization of the peptides. To get an insight into the distribution of local H+ concentration in the proximity of a polyelectrolyte chain, a modified polyelectrolyte structure was used with a fluorescent pH- indicator, covalently attached at the end of the chain. Ionization of the pH-responsive fluorophore revealed its effective pK which was compared with the local...

Use of selected concepts for active release of myofascial tissue
Chaloupková, Barbora ; Tichá, Monika (advisor) ; Bakulová, Kateřina (referee)
bakalářské práce AJ Author: Barbora Chaloupková Tutor: Bc. Monika Tichá Title: Use of selected concepts for active release of myofascial tissue Abstract: The theoretical part of the work first describes the morphology and physiology of fascial tissue, briefly describes the muscle tissue. Furthermore there are introduced and desribed selected concepts affecting myofascial tissues of the musculoskeletal system, which use the active participation of the patient in therapy. The theoretical part of the work includes the concept of Fascial release technique, the concept of Fascial fitness and methods of myofascial autotherapy. The practical part of the bachelor thesis evaluates the concept of Fascial release technique during physiotherapeutic intervention in two patients with pain in the dorsal part of the lower limbs of functional origin. The concept of Fascial release technique was evaluated according to the data from the input and output kinesiological analysis of the treated patients, subjectively evaluated by the patients through questionnaires and from the perspective of the therapist. By both patients, their difficulties in the monitored segments of the musculoskeletal system were alleviated. Active patient participation in therapy reduces the physical demands of myofascial therapies for the...
