Unconventional machining processes
Exnerová, Jitka ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
This thesis deals with the methods of the unconventional machining. The first part outlines the history of the machining methods, their characteristic and use follows. The second part aims at the method of the water jet, its technology, safety use, its advantages and disadvantages. Subsequently the thesis presents selected companies dealing with water jet cutting technology. At the end the thesis presents the environmental impact of the water jet cutting.

Influences of process parameters and material on technological forming limits of given componenet
Exnerová, Jitka ; Peterková, Eva (referee) ; Samek, Radko (advisor)
Master s thesis is focused on flaring of tubes endings. There are also mentioned theoretical pieces of knowledge which relate to tubes endings by a flat edge and a cone. The following experiments performed with the own material and tools made by the author s design. Experiments in the production of the flat collar led to the speedy rotation of the sample ending. Experiments with the conical ending brought valuable results from the point of view of comparison of theoretical and measured powers, distribution of thicknesses and utilization of the deformation web to set voltage-deformation state. The dimension excent of the conical ending was limited by the formation of buckling in the cylindrical part of the tube.

Intergenerational opinions on euthanasia
EXNEROVÁ, Jitka
I have chosen the topic of euthanasia for my bachelor´s thesis. I find the topic fairly problematic and it is frequently discussed in the media as well. On the other hand, there is palliative medicine which is rarely spoken about. In my thesis I wanted to highlight the possibilities of palliative care which seem to be neglected in our society and to underline possible risks of euthanasia. Moreover, I wanted to find out which factors influence the opinions on euthanasia in individual age groups. I was interested in the way people look upon euthanasia and palliative care. The thesis includes a theoretical and a practical part. The theoretical part deals with euthanasia, palliative care, pain, suffering, dying and death. In the practical part there are examples of abbreviated dialogues connected with this topic. In order to gain necessary information I have chosen the method of qualitative research and that of a narrative and semicontrolled dialogue. All the dialogues were recorded on a dictaphone with the consent o feach addressed person and then transferred into written form. They were abbreviated and preserved in colloquial language form for the sake of their authenticity. Some people wanted me to ask them questions. I have found out that palliative care still presents an unknown quantity for most people and the word hospice makes them feel scared, they have distorted ideas. On the contrary, they are pretty familiar with the word euthanasia, almost all of them have come across it and know what it is about. I have decided on four age categories. I have addressed at least one woman and one man from each category to be able to hear the opinion of both sexes. Respondents were chosen by chance. During the research I have found out that the intergenerational opinions on euthanasia are becoming less contradictious. I suppose that the goals of my thesis have been reached. Taking the information which has been found out into consideration it would be of great benefit if the media and the responsible organisations would provide our society with more information about the possibilities of palliative care.
