Verification of corrosion resistance of hyperduplex austenitic-ferritic stainless steel
Trkola, Ota ; Pernica, Vítězslav (referee) ; Kaněra, Miloš (advisor)
The bachelor's thesis deals with the corrosive resistance of a cast hyper duplex austenitic-ferritic steel. It is a prospective stainless steel that could be applied in foundry practice as a casting material in the future. The theoretical part contains an analysis of the principles of corrosion and the influence of the chemical composition on the structure and properties of steel. A significant part concerns duplex steels, especially their resistance to local types of corrosion expressed by the theoretical PRE number. The practical part of the work focuses on testing the corrosion resistance of hyper duplex steel using the corrosion test according to the ASTM G48 standard. The evaluation compares the corrosion attack with other alloys.

Production of castings from austenitic-ferritic hyperduplex stainless steels
Kaněra, Miloš ; Pernica, Vítězslav (referee) ; Záděra, Antonín (advisor)
The thesis deals with hyper duplex stainless austenitic-ferritic steels and their mechanical and castability properties. The evaluation of resistance to pitting corrosion is divided by PRE values. Steels with a PRE value higher than 48 belong to the group of hyper duplex steels. The theoretical part contains an introduction to the chemical composition, structure and properties of these steels. The practical part is focused on the conditions of tendency to crack castings during solidification and cooling. Furthermore, there is evaluated influence of intermetallic phases on mechanical properties.

Spectrum of Psychotherapy from the perspective of Ken Wilber' s' Integral Theory
Rosendorfová, Johana ; Chrz, Vladimír (advisor) ; Tylš Adámková, Jana (referee)
In this theoretical thesis, I will first present my own condensation of the development of Ken Wilber's integral (structural-hierarchical) theory of the development of consciousness. In the second part, I compare Wilber's theory with psychodynamic theory, from which Wilber originally came. The main figure of comparison here will be Michael Washburn's concept of transpersonal development, which is anchored in a neo-Jungian approach. The comparison shows that one of the main distinguishing features of transpersonal theories is the topic of pre/trans fallacy and the location of the U-turn, i.e. the approach to the nature of the process of regression in personality development. In the last key part, I reflect on the possibilities of connecting the integral theory with psychotherapy and show that it is a theory that allows us to think systematically about psychological issues and psychotherapy directions. When analyzing the levels of consciousness of the integral theory, it turns out that the transitions between individual levels are points of a possible crisis of self. Psychotherapy can offer support and guidance, which can be specifically focused on the pitfalls in a given fulcrum. KEYWORDS integral theory, pre/trans fallacy, regression, development of consciousness, transpersonal psychology, psychotherapy

A comparison of transpersonal theories of consciousness development with regard to the psychedelic experience
Koubková, Daniela ; Chrz, Vladimír (advisor) ; Adámková, Jana (referee)
This theoretical thesis is focused on mapping and comparing the leading psychological transpersonal approaches to the conception of development of consciousness of an individual. This research is exploring the theory of Ken Wilber, Michael Washburn and Stanislav Grof also paying attention to the main disagreement among them regarding the confusion of prepersonal and transpersonal spheres of consciousness. This disagreement is further elaborated in an effort to find a conclusion and to seek for an integrative theory. The theories are compared with regard to the findings about psychedelic experience. The psychedelic experience is psychologically elaborated with emphasis on the current scientific knowledge in the field and their embedding in the context of the developmental theories of consciousness taking the effort of unravelling the pre/trans fallacy and the clinical implications into account. KEYWORDS Developmental theory, consciousness, transpersonal, psychedelics, pre/trans fallacy
