Spindle and tool stand design integrated into a robotic machining cell
Totušek, Josef ; Klíč, Daniel (referee) ; Štěpánek, Vojtěch (advisor)
The subject of this bachelor thesis is the structural design of a stand for spindle and tool storage, integrated into a robotic machining cell. The theoretical part is divided into several chapters that focus on the topic of end-effector changing system and tool holders, along with the introduction of selected types. The practical part includes partial designs necessary for implementing automated operations in robotic machining. The crucial part involves the storage of the spindle in the stand, for which three conceptual designs are created, followed by an evaluation based on a multi-criteria analysis. Furthermore, the realization of the spindle connection with the exchangeable system and the complete integration of pneumatic and electrical circuits are carried out. An assembly drawing is included in the drawing documentation.

Media reflection of minister Alois Rašín and his assassination in contemporary daily newspapers
Totušek, Jaroslav ; Bednařík, Petr (advisor) ; Končelík, Jakub (referee)
This masters disertation is focused on an important Czech politician Alois Rašín and his reflection in the period daily newspapers. The researched period is from October 1922 to February 1923. Three important events related to Rašín happened in that period - his second appointment as the minister of finances and his assassination. In the first chapter I write about Rašín as a person and politician. In the second chapter I focus on the political situation during the First republic and Rašín's uneasy relations to others. The third chapter is the research I do using the period daily newspapers. I epitomize my findings in the summary.

Long term investigation of resveratrol content in moravian red wines in relation to climate conditions
Vrchotová, Naděžda ; Tříska, Jan ; Totušek, J. ; Balík, J.
The considerable commercial importance of wine together with the necessary quality control and investigation of the biological quality of constituent compounds leads to the development of adequate and reliable methods for the determination of macro- and micro-components in wine. Although wine contains a large amount of known compounds e.g. volatile (fl avour compounds), semi-volatile (phenolic) and non-volatile components (pigments), new compounds from all the above mentioned classes are still found in wine and are under heavy investigation, especially regarding their biological activity and their relation to the vinifi cation processes. Th e most signifi cant and famous due to the so-called French paradox is resveratrol-3,4´,5-trihydroxystilbene. Resveratrol is a stress metabolite formed in the grapevine in response to abiotic (UV irradiation) and biotic stresses (Botrytis cinerea). UV irradiation transforms trans isomer to cis form. But according the recent literature cis resveratrol could be also a result of organic farming – natural means of defence in organic viticulture against fungal infections. In our study we have investigated resveratrol content in diff erent vineyards in relation to annual mean temperature, precipitation and sun irradiation.

Fruit-vegetables juices preserved by high pressure
Houška, M. ; Strohalm, J. ; Totušek, J. ; Lefnerová, D. ; Tříska, Jan ; Vrchotová, Naděžda ; Gabrovská, D. ; Průchová, J. ; Gřesová, P. ; Loučková, K. ; Fiedlerová, V. ; Paulíčková, I. ; Winterová, R.
The fruit/vegetables juices pasteurived by high pressure were developed and tested for their antimutagenic activity.
