Differences and similarities of sound-colour synaesthesia (chromaesthesia) and other related perceptual phenomena
Kysilková, Lenka ; Šebesta, Pavel (advisor) ; Chromý, Jan (referee)
Synaesthesia is a perceptual phenomenon found in a small percentage of the population. Stimulation of one perceptual modality triggers a second sensation in other non-stimulated modality. For example hearing sound would induce concurrent percept of colour. This thesis is focused around phenomenological evidence and possible mechanisms underlying synaesthesia. Resemblance of synaesthesia to other similar perceptual phenomena like crossmodal correspondences makes it difficult to define by researchers. I investigate differences and similarities to crossmodal correspondences and also critically review the methodology of experimental studies. Keywords Synaesthesia, crossmodal correspondences, perception

Endogenous markers in the etiopathogenesis of abdominal aortic aneurysms
Houdek, Karel ; Moláček, Jiří (advisor) ; Bachleda, Petr (referee) ; Šebesta, Pavel (referee) ; Staffa, Robert (referee)
Introduction Prevalence of abdominal aortic aneurysm is 2-6%. Aneurysm is on the leading possitions in death cause. Lot of patients die do to ruptured aneurysm. The etiology of abdominal aortic aneurysm remains unknown. Current treatment(resection or endovascular)is not indicated for everyone. We don't know the right conservative (pharmacological) treatment. Aims With our study, we would like to confirm the impact of atorvastatin on experimental abdominal aortic aneurysm. We would like to evaluate and quantified changes in the composition of an aneurysmatic wall under the effect of atorvastatin. Other aim is to make a summary of known knowledge of this disorder. These knowledges can help in searching for new treatment options. Methods Comparison of 2 groups of pigs with experimental abdominal aortic aneurysm. Group treated with atorvastatin and group without any pharmacological influencing. Comparing of aneurysmal growth rate. Evaluation of changes of the wall structure in both groups using a stereological tools. Review of published data. Results In our experimental work atorvastatin did not slow down the growth of the aneurysm. Effect was on the histological structure of the aneurysmatic wall. Wall structure of the aneurysm in group treated with atorvastatin was really close to wall without any...

Possible Relationship between Other-Rated and Self-Rated Vocal Quality in Body Image Concept
Stolařová, Petra ; Varella Valentova, Jaroslava (advisor) ; Šebesta, Pavel (referee)
for diploma thesis: Possible Relationship between Other-Rated and Self-Rated Vocal Quality in Body-Image concept Petra Stolařová The aim of this study was to investigate whether it is possible to consider voice as a part of Body-Image concept. We examined the perception of one's own voice and its affect on individual's personality and behavior. In addition, we decided to examine this fact in two culturally different samples - Czech and Brazilian. We collected comparable vocal recordings in both cultures - two recordings of singing and two recordings of speech, we also collected questionnaire data regarding perception of one's own voice and singing, scores of seciosexuality and additionaly in the Czech sample we collected self-reported self-esteem. Subsequently, we collected attractiveness ratings of these vocal recordings by independent raters within the two chosen cultures. Using statistical methods, we found that the rated and self-rated voice quality (both speech and singing) partially correlated, but these correlations differed in relation to gender, and population. The Czech sample revealed that neither self-rated nor other-rated quality of voice had affect on self-esteem. Also, it appears that self-rated quality of singing has an impact on sociosexuality in Czech women and Brazilian men,...

Morphology of the Abdominal Aortic Aneurysm
Eberlová, Lada ; Valenta, Jiří (advisor) ; Stingl, Josef (referee) ; Šebesta, Pavel (referee)
Dissertation Abstract Abdominalaortic aneurysm (AAA) is a serious disease. Its prevalence is in the developed countries about 3%. As an aneurysm is considered a dilatation of all layers of a vessel wall over 3 cm. Majority of AAA are small and asymptomatic, and although the risk of rupture increases with the size of aneurysm sack, even the small aneurysms rupture. The rupture mortaliry ranges about 70 %. Surgical treatment is indicated in the asymptomatic patients in diameter of AAA over 5 cm. The average speed of growth of AAA is 0.3 cm per year, e.g. in the early diagnosed patients there is a several years interval for a pharmacolocical influencing of the progression of this disease. Knowledge of pathogenesis is essential for any targeted pharmacological treatment. Our prospective, non-randomised studies are based on the application of the stereological methods for the histopathological assessment of the AAA samples. The acquired data enable the statistical analysis, including the null hypothesis testing. In our study analyzing the histopathology of AAA aortae of 65 patients (65 walls and 55 thrombi) and 6 normal abdominal aortae from the organ donors we assessed the following parameters: the area fractions of collagen and elastin, and the length density of elastin in intima and media, the area...

Water soluble foundry binders with heat dehydratation hardening
Šebesta, Pavel ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
Environmental pressure on foundries has forced manufacturers to develop new organic and inorganic binders. One of the options is water soluble binders that can be hardened by dehydration. In addition to tenacity characteristics and regenerability of the forming mixtures another considered aspect is the amount of emissions generated by casting. Use of these new binders does not require expensive modifications of the machines for work with the forming mixtures.

Position harp in music by the year 1720
Šebesta, Pavel ; Boušková, Jana (advisor) ; Boušková, Jana (advisor) ; Rak, Štěpán (referee) ; Zelenka, Milan (referee)
Subject those work is position harp in European music by the year 1720, when discovered first pedal- activated systems. The earliest known use of the word hearpe was by Venantius Fortunatus, Bishop of Poitiers, in about 600. Early medieval Latin terminology is also ambiquous. Cithara was used for both lyres and harps, kytharis etc.Confusions as to terminology still existed as late as 1511, when Virdung wrote: What one man names a harp another calls a lyre.The harp's use ranges from reliqious ritual to pure entertainment. Harpists are depicted in royal chambers, salons, banquet scenes and processions as soloists or in ensembles.Harpists have accompanied themselves singing ballads, reciting oral history and epic poetry or accompanying rituals of various types. In the ancient world, solo harpists and harpists in large ensembles were usually men while harpists who played in small chamber ensembles were often women.
