Woman's and men's roles in the Iban tribe in Kalimantan
Remešová, Blanka Michaela ; Vrhel, František (advisor) ; Pargač, Jan (referee) ; Uherek, Zdeněk (referee)
The doctoral thesis studies woman's and men's roles in the Iban tribe in Kalimantan. As a result of the growing influence of the majority society, these crofters, originally living in the heart of the primeval forest, have undergone many changes in the last 20 years. They have to cope with a different lifestyle and values hectically imposed upon them to a large extent. This process influences the structure of the whole society, and affects also the traditional system of male and female roles. Through deep study and analysis of female and male activities, I have studied penetrability of the assigned roles, which start to appear as impaired or non-functional, and which determine the creation of new structures.

The most important Toraja rituals and their current form
Budiman, Michaela ; Oberfalzerová, Alena (advisor) ; Dubovská, Zorica (referee) ; Remešová, Blanka Michaela (referee)
The presented doctoral thesis called The Most Important Toraja Rituals and Their Current Form deals with the ethnic group of Toraja, who inhabit the province of Tana Toraja, located in the southern part of the Indonesian island of Sulawesi. The work presents Toraja culture with a focus on two of the most important rituals - funerals and weddings. The goal is to outline the original form of these rituals and to capture the major social and religious changes in Toraja society since the Dutch missionaries first entered the area of present day Tana Toraja at the beginning of the 20th century. The Dutch introduced Christianity to the Toraja people, who until then adhered to their autochthonous religion Aluk Todolo. Almost all of the Toraja people gradually converted to Christianity, though they did not fully leave behind their original customs. In this work, I advert to how much the newly accepted Christianity influenced contemporary Toraja rituals, with an emphasis on the shift in their form and meaning. The work is based mostly on the field research; I implemented the method of concentrated observation. I also conducted and recorded many interviews with local people. After returning from the field, I analysed all of the collected text, voice, and video materials. Based on its analysis and the specialized...

Metallic biomaterials
Bunganič, Pavel ; Remešová, Michaela (referee) ; Horynová, Miroslava (advisor)
In this bachelor thesis the objective was to make a summary of the basic metal-based biomaterials, which are presently used. These single materials are described and its suitability for various appliacation is evaluated depending on its chemical structure and microstructure, and its mechanical and corrosion characteristics.

Technology of Galvanic Anodization of Non-ferrous Materials and Its Alloys
Remešová, Michaela ; Hadraba,, Hynek (referee) ; Čelko, Ladislav (advisor)
The thesis is focused on the theoretical description of the technology of anodizing of aluminium, magnesium, zinc and their alloys. In this work, methods for formation of oxide layers and the used chemical processes are described in detail. The experimental part of this work deals with formation of oxide layers on aluminium, magnesium and zinc of high purity under different conditions. Oxide layers of different thicknesses were created on all three experimental materials. Aluminium was anodized in a bath of 10% H2SO4, magnesium in the bath of 1 mol/dm3 NaOH, and zinc in the bath of 0.5 mol/dm3 NaOH. Processes were carried out at laboratory temperature. On the aluminium, continuous oxide layer was formed. Furthermore rule "312" was verified, that can indicatively be used for calculating the thickness of the resulting oxide layer on the aluminium. When using lower current of 0.08 and 0.2 A for magnesium anodizing, dark colored layer was created comparing to higher current of 0.5 A. More rough appearance of the oxide layer was produced with increasing voltage. Further, it was observed for magnesium that the resulting layer comprises of two sublayers. For zinc, black colored layer was created when the voltage 20 V and current from 0.4 to 0.5 A were used. In the layer, two sublayers were also observed. For lower voltage and current (0.05 A, 0.17 V), formation of the oxide layer on the zinc does not occur, but the crystallographic etching was observed.

Anodizing of Aluminium and Its Alloys
Remešová, Michaela ; Julišová, Martina (referee) ; Čelko, Ladislav (advisor)
This thesis focuses on the hard anodic oxidation of aluminum and its alloys. As an experimental materials were used various aluminum materials, produced by cold forming and casting. The work contains information about chemical composition of the base materials, photographs of their microstructure, the results of surface roughness before and after anodic oxidation, photo anodized layer, measurements hardness oxide layers. For study were used methods light microscopy, scanning electron microscopy, surface profilometry and microhardness measurements.
