Suggestion of a Financial Concept for the Development of a House
Šimek, Pavel ; Pelc, Jiří (referee) ; Škapa, Stanislav (advisor)
The diploma thesis analyzes available methods of financing of a new housing construction with the focus on the possibilities of concurrent investment. The above analysis is demonstrated in a model case study. Practical part contents selection of the products to be analyzed from each evaluated field: suitable mortgage loan, finance market investment, the investment to the alternate heating equipment of the home and photovoltaic power plant. Than demonstrate the possibilities of decreasing the price of the loan with the assistance of concurrent investment into the financial markets or the alternative investment. The risk of investing has been taken into consideration as well. At the end are demonstrated comparative analysis and evaluation of all financing possibilities resulting in suggesting the most suitable method of home loan financing.

Nuclear reactor power detectors based on Cherenkov radiation measurement
Čejka, Lukáš ; ČEZ,, Ondřej Zlámal, (referee) ; Katovský, Karel (advisor)
This work deals with the connection between the luminance of Cherenkov radiation in a nuclear reactor and his power. Cherenkov radiation arises when charged particle passing through the medium if their speed is higher than the phase velocity of light in that medium. In water moderated reactors, it is caused by secondary electrons produced by absorption of gamma rays. The measurement is done using the camera and software for photometric luminance measurements. Furthermore, there is mentioned the use of Cerenkov radiation detection to measure burnout of spent nuclear fuel. There are examples of usage of Cherenkov radiation detection to measure of nuclear reactors power, including an analysis of the measured results on research nuclear reactor VR -1. The measured results show increasing intensity of Cherenkov radiation with increasing reactor power, but residual detection response caused by delayed gamma radiation was observed after the rapid decrease of the reactor power. Possible use of detection luminance of Cherenkov radiation is in monitoring unforeseen increase in reactor power or in the control of used fuel.

Determination of tensides in waters by separation methods
Brestovská, Marta ; Řezáčová, Veronika (referee) ; Čáslavský, Josef (advisor)
Surfactants are synthetically made surface-active agents contained in washing and cleaning products. They decrease the surface tension and remove dirt. Surfactants can be divided into three basic classes: anionic, cationic and non-ionic. Thanks to the massive use they penetrate into waste water and can disturb the environment. This diploma thesis deals with the occurrence of surfactants in water and their determination by separation methods, especially LC / MS.

Determination of surfactants by capillary zone electrophoresis.
Tůmová, Klára ; Zemanová, Jana (referee) ; Řezáčová, Veronika (advisor)
Surfactans are synthetically made surface-active ingredients contained in washing and cleaning products. They decrease the surface tension and remove dirt. Surfactans can be divided into four basic classes: anionic, cationic, non-inonic and ampholitic. The most commonly used are the anionic ones. Thanks to the massive use they penetrate into waste water and can disturb the environment. This thesis is focused on the optimization methods and the determination of three anionic surfactants by capillary zone electrophoresis.

Partial slip in liquids studied with high-frequency shear oscillations
Vlachová, Jana ; doc.Ing.Marian Lehocky, Ph.D. (referee) ; Johannsmann, Diethelm (advisor)
Byl studován kontakt mezi koulí a deskou pod tangenciálním zatížením ve vodě. Jako zdroj střižných kmitů byl použit akustický rezonátor (křemíkové mikrováhy – QCM). Kontakt koule s povrchem resonátoru indukuje změnu resonanční frekvence a šířky pásma. Byla měřena změna frekvence f a změna šířky pásma v závislosti na amplitudě oscilací. S rostoucí amplitudou docházelo k poklesu f a růstem , což je chování typické pro parciální skluz. Díky aplikaci Cattaneo-Mindlinova modelu byl vypočítán kontaktní poloměr a třecí koeficient. Kontaktní poloměr při nízké amplitudě stoupal při zvětšujícím se normálovým zatížením. Tato závislost se dobře shodovala s JKR modelem. Třecí koeficient se nacházel v odpovídajícím rozsahu. Při zvyšování externí normálové síly, docházelo k nepatrnému snižování hodnoty třecího koeficientu. Toto chování je vysvětleno příspěvkem adhezivních sil k totální normálové síle. Výpočtem byly získány dva typy třecích koeficientů, první ze změny frekvence f a druhý ze změny šířky pásma . Tyto dvě hodnoty se spolu shodovaly z ± 20 % pro měření prováděná ve vodě, zatímco pro dvě měření prováděných na hydrofilním povrchu ve vzduchu se lišila. Tento nesoulad poukazuje na nedostatek Cattaneo Mindlinovy teorie a mohl by být vysvětlen přítomností kapilárních sil.

Vliv těžby ropy na norskou ekonomiku
Malkovský, Michal ; Doležal, Ondřej (advisor) ; Pekárek, Štěpán (referee)
Norway serves as a unique example of a developed country whose economy is dominated by export of natural resources. Thanks to its large petroleum reserves Norway has become one of the richest countries in the world. This thesis examines how the country has coped with its transformation and if it has avoided the so-called resource curse. It deals with the effects of the oil industry on the other sectors of the economy as well as on Norwegians' wellbeing. As the revenue from the petroleum production has grown, the state has implemented number of economic policies with the aim to utilize it in favour of the weakened industries and the society as a whole. So far, the oil industry has brought Norway prosperity thanks to sound governance and fitting policies. The question is whether the measures are sufficient to tackle both the decreasing production and prices of oil while maintaining the advantage the country has gained.

Source separation and nutrient utilization for elimination of eutrophication of water reservoirs
Holba, Marek ; Černý, M. ; Došek, M.
Sustainable society development and the improvement of water environment quality together with soli quality is tightly connected with separation at source, biodegradable waste and nutrient recycling from wastewater to agriculture. Once we recycle nutrients from wastewater then we can reduce fossil fuel consumption and decrease nutrient input into water bodies. This attitude can be expressed by acronyme NEW (N - nutrient, E - energy, W - water) that lead to the nutrient recycling, energy consumption decrease and enhancement of water quality.

Vliv PUFA n-3 na expresi genů kódujících proteiny řídící homeostázu cholesterolu
Hyblerová, Dagmar
The aim of this study was to confirm that the polyunsaturated fatty acids n-3 (n-3 PUFA) have a positive effect on plasma lipids. These acids can reduce cholesterol by increasing gene expression Insig-1 while decreasing the expression of genes encoding Hmgcr and Ldlr. We tested in experimental rats, which were added to the feed mixture of 6 % safflower oil , 6 % fish oil or 6 % of the oil from the algae Schizochytrium. Relative gene expression was Insig-1 in the test group with addition of fish oil to 120% of controls (P<0.05) and in the group with addition of oils from algae Schizochytrium the relative expression of 170 % of control (P<0.05). These results confirm our hypothesis, only a part, as the relative expression of the gene and Hmgcr and Ldlr was in the test group with addition of fish oil 103% (P>0.05) and 101 % of control (P>0.05) and in the group with addition of oils from algae Schizochytrium the relative expression of 117% (P>0.05) and 156 % (P>0.05) compared to control. Thus, to reduce the relative expression of these genes did not. However, we have shown that n-3 PUFA contribute to a reduction in plasma cholesterol and in this case up to 20 % of control. The concentration of cholesterol in the group with addition of safflower oil was 1.35 mmol.l-1, the group with the addition of fish oil 0.98 mmol.l-1.

Pre-hospital emergency care of patients with carbon monoxide intoxication
HAJÍČKOVÁ, Iva
The bachelor's thesis deals with the topic of the pre-hospital emergency urgent care for patients poisoned by the carbon monoxide. This issue has been known already for a number of years, but only in the last time it started to be presented more frequently in media. The carbon monoxide is a colourless gas which is not recognizable by senses. It comes into being as a secondary product of the not perfect combustion of the carbonaceous substances. The seriousness of these symptoms depends on the intensity of intoxication. The target of this thesis was to map the issue of treating the client with the suspect of poisoning by carbon monoxide from the viewpoint of the Medical Rescue Service and other components of the Integrated Rescue System. Moreover I verified the knowledge of lay public in connection with the intoxication by carbon monoxide. The research took place in the form of half-managed talks with the medical rescuer and physicians of the Medical Rescue Service of the South Bohemian Region. The same research procedure was carried out in the Firemen Corps of the South Bohemian Region. The respondents were asked eight questions finding out how many cases of the carbon monoxide intoxication they encountered in their practice, what the most frequent reasons caused the intoxication and what care was provided to the intoxicated persons. Among the lay public, the knowledge was established by the survey method. Also this research complex consisted of nine respondents, having been addressed accidentally in the schools, during travelling in town, in business centres and during sport events. Most frequently were among the enquired persons: students, also a nurse or deputy director of a company. The respondents answered seven pre-printed questions. The sense of these questions was to find out if at least a small part of the lay public has some idea of the intoxication of the carbon monoxide. If they ever encountered the intoxication by the carbon monoxide, how they would behave in this situation and in what way they would provide the first aid. In both parts of the research, the results are presented in the charts, to have a better survey. In has turned out in the talks concerning the occurrence of the intoxication by the carbon monoxide that the length of practice is not very important, because also the persons working in the branch for a longer time have no such high number of interventions concerning intoxication by the carbon monoxide as some of their colleagues working in practice only several years. Moreover it was established that the most cases of intoxication appeared in connection with geyser and subsequently during fires. The health state of affected persons ranged from the light intoxication up to very heavy intoxication with the subsequent death. Depending on these states, the experts provided the adequate pre-hospital care completed subsequently in the hospital facility. It turned out that although the most respondents were not able to say if the number of intoxications by the carbon monoxide has been increasing or decreasing, their answers are identical in the most cases and indicate that their number has been rather decreasing Concerning the lay public, only a small part of respondents was interviewed and the result of research cannot be quantified. This part of the research has shown that although nobody of the enquired persons encountered the intoxication by the carbon dioxide, the respondents know in the most cases how they should behave in case of the intoxication and in what way the first aid should be provided. The most frequent source of their information of carbon monoxide intoxication and the first aid was the knowledge acquired during studies. Further details concerning the research are specified in more detail in the discussion. The general awareness of people concerning the intoxication is on a good level thanks to education and media.

Utilisation of Nordic walking in physiotherapy
VOLMANOVÁ, Martina
Nordic walking is modern exercise activity using special poles when walking. It is quadrupedal locomotion, when all limbs are in steady manner and so the stress and tension of muscles are equally distributed, which is beneficial to human posture. The use of any exercise activity in current modern and accelerated world is very beneficial and positive. Nordic walking is one of the exercise activities suitable to increase body control, for maintenance and enhancement of physical fitness. Nordic walking can be also used as one of the physiotherapeutic activities helping in motor system treatment. The theoretical section of the thesis briefly describes historical origin of Nordic waking. Further we can find the definition of basic equipment which is an integral part of this sport. Technique of the sport is described in every detail. The most frequent faults made against the technique of Nordic walking that people should avoid, are also outlined in the theoretical section of the thesis. There is suggested appropriate intensity of walking for each age group, suitable terrain, and also weather conditions. Major part of the theoretical section contains information about main effects of Nordic walking on single systems and about benefits resulting out of it. The aim of the Bachelor thesis is to outline problems and appropriate technique of Nordic walking and to suggest using this sport in physiotherapy. To reach the aims, there was used qualitative research, using 3 individuals 2 men and 1 woman. All 3 individuals suffered from chronic pain of various parts of the spine. There was taken history during first meeting and done kinesiological analysis. After that they were instructed in detail to master correct technique of Nordic walking. Participants were walking with poles twice or three times a week for 8 - 9 weeks. They were recording the distance and average speed into the tables they received during entry examination. There was also done kinesiological analysis again during the final examination. Participants also underwent unstructured interview to provide feelings and observations of whole investigation. These results were subsequently recorded into simple charts and tables that made easier data interpretation of the investigation. Findings based on participants? subjective assessment of back pain showed that the most remarkable changes concerned back pain that participants suffered from. All participants considered the investigation as positive and very relieving of the pain. Kinesiologic analysis showed apparent changes of the range of joints, namely in shoulder and hip joints. Participants themselves confirmed feeling better shape of the muscles and in general better physical fitness. Participants also noticed better body control; various asymmetries became symmetric what caused bilateral balancing of the tonus in various muscle segments. The discussion section of the thesis contains comparison of the results from this thesis and findings of Bronislav Kracmar?s two studies. He concluded that Nordic walking is not such beneficial exercise but also has a disadvantage. He found, using EMG, that when Nordic walking, there is present decreased activity of gluteus medius muscle which decreases demands for lateral stabilization of the pelvis unlike common bipedal walking. His investigation brought also positive result which is increased activity of latissimus dorsi muscle and deltoideus muscle which helps to stabilize shoulder joint. Thanks to the support of upper limb, diagonal muscle chains can interconnect as far as to opposite lower limb and so movement of high quality can be developed. Regarding this investigation, Kracmar recommends Nordic walking as proper physical activity relieving back pain. Nordic walking can be used in physiotherapy as an exercise activity to prevent motor system disorders as well as internal disorders. It can be also used as supplemental therapy during special cure of these disorders.
