Design Study of Triflux Cylinder Head for SI Engine
Provazníková, Martina ; Rasch, František (referee) ; Svída, David (advisor)
This diploma thesis concern with substance and possibilities of contemporary computational fluid dynamics or CFD. Further it engages in design of intake ports of triflux cylinder head on the basis of cylinder head of Škoda 1,2 HTP that was digitized by 3D scanner. After design of standard intake ports and triflux system’s intake ports is maden simulation of flow through these intake ports with the assistance of CFD program.

Mathematical analysis of models arising in continuum mechanics with implicitly given rheology and boundary conditions
Maringová, Erika ; Bulíček, Miroslav (advisor)
In the thesis, we study the Navier-Stokes-like and the Navier-Stokes-Fourier- like problems for the flows of homogeneous incompressible fluids. In the first part of the thesis, we introduce a new type of boundary condition for the shear stress tensor, which includes the time derivative of the velocity. Therefore, we are able to capture the dynamic response of the fluid on the boundary. As the second part of the thesis, we include the published journal article co-authored by J. Žabenský on the Navier-Stokes-Fourier-like problem formulated in the complete thermodynamic setting. In both parts, the constitutive relations are formulated implicitly with the use of maximal monotone graphs. The main result of the thesis is the existence analysis for the above mentioned problems.

Conditions of dolomitization at selected localities of the Barrandian
Novotný, Petr ; Zachariáš, Jiří (advisor) ; Suchý, Václav (referee)
Research on dolomitic limestones and dolomites from selected localities of the Barrandian, stratigraphically related to the Scyphocrinites Horizon near the Silurian-Devonian boundary, showed the occurrence of two distinct types of dolomite - diagenetic and epigenetic - differing in petrography and genesis. The diagenetic dolomite is quantitatively predominant. It is finely to moderately coarsely grained with crystal size from 20 μm to 450 μm. Crystals of this dolomite form mostly xenotopic and hypidiotopic textures (occasionally even idiotopic). This type of dolomite formed at low temperature and depth by recrystallization of a carbonate mud during early diagenesis, or during subsequent deeper burial. It is also possible that it originated from recrystallization of previously formed syngenetic dolomite. Fine texture of the diagenetic dolomite is a proof of fast dolomitization and of formation of numerous crystallization centers. Very fine-grained variant of dolomite was also detected (forming aphanotopic texture, size of crystals below 0,002 mm). The epigenetic dolomite, also known as baroque or saddle dolomite, is less common than the former one. It forms white, milky-turbid or clear crystals of large dimensions (0.8 - 3.1 mm). The shapes of these crystals are conspicuous, variously twisted,...

Keeping of drinking habits in hospices in case of walking patients
MATOUŠEK, Jan
This diploma thesis deals with the problem of the drinking-regime keeping in case of patients in hospices and in case of seniors living on their own. The phrase 'drinking regime' means correct fluid supplement which is necessary for a human body. It is the main way to recover the daily fluid loss. The intake of fluids is essential at any age, though even more essential it is at the old age, when the human body encounters considerable natural decrease in amount of fluids and what is more, when a man also loses the feeling of thirst. To stay healthy and in a good shape, it is necessary to maintain a balance between the intake and expenditure of fluids during a day. From this point of view, it is important to have a regular fluid intake during a day - especially to drink sth. before one starts to feel thirsty.

Physical experiments with simple materials
BARTL, Adam
This diploma thesis "Experiment with simple tools" is about preparation experiments made from object of daily use or different commercially available tools. Experiments are direct to fluid subject. Experiments are constructed to homemade use. Working students? sheets are prepared for these experiments. They are attached to this thesis. These students sheets serve as leading in independent work. Students after them can try experiment and brush subject up.

Constipation - problem of immobile patients
HULIČKOVÁ, Tereza
My thesis deals with constipation in immobile patients. The research was carried out by collecting data using the questionnaire method. The questionnaires were focused on immobile patients of all ages hospitalized in any units in the České Budějovice hospital, Inc. The objective of this thesis was to survey the drinking regimen and eating habits in immobile patients and to analyze their impact on the development of constipation. I set three hypotheses: The first hypothesis suggests that immobile patients´ alimentation does not include an increased requirement for dietary fiber. My research shows that patients´ diet at home contains more fruits, vegetables and whole meal bread. A diet therapist hardly ever comes to see hospitalized immobile patients. Most patients are not on any diet which would limit the intake of particular nutrients. The first hypothesis was confirmed. The second hypothesis suggests that immobile patients do not observe the drinking regimen. The research data analysis shows that patients´ fluid intake is the same no matter if they stay in hospital or at home {--} it is about 1- 2 litres a day. The fluid intake depends on patients´ age, weight and health condition. It is possible to say that immobile patients observe the drinking regimen. The second hypothesis was not confirmed. The third hypothesis suggests that immobile patients do not have enough privacy while they pass stool. They feel ashamed and these feelings also raise the constipation development. There is a lot to improve in this respect, the nursing staff should be aware of the fact that immobile patients need more intimacy at passing bowel motion. It is not surprising that most immobile patients feel the lack of privacy in hospital. In my opinion not enough attention is paid to the question of privacy in hospitals. This has a negative impact on patients´comfort. Patients´ diet should include more dietary fiber. Individual consultations with a diet therapist are advisable for patients. The nursing staff should also focus on the patients´ drinking regimen. The right diet and drinking regimen may contribute to constipation prevention. The empathetic, holistic, psychological and sensitive approach to patients should improve patients´ condition and alleviate their pain. Each nurse should make her best to prevent patients from feeling undignified in hospital.

The drinking regime at elevated bodies burden by the recretional form of fitbox
ŠIMOTOVÁ, Jaroslava
The work is dealing with the drinking habits in the recreational form of fit-boxing. The specifics of the drinkling habits are thoroughly described in the theoretical part of the work. The characteristics during heavy physcial endurance as well as the importance of drinking habits are defined here. The drinking habits of active fit-boxers is monitored in the practical part. These habits are then compared with a group of non-active people with sitting or non-movement jobs. From the practical examination it is obvious that those active involved in the fit-boxing have higher consumption of liquids and superior drinking habits with comparison to the group which is non-active.
