The work deals with the theme of women's life through the stages it passes on its way to the conclusive process of ageing and dying. It tries to study this fenomen through the structure, shape changing and sarcolysis that permeates the cycle of human life.

This work was focused on the study of hydroxyapatite based bioceramic materials. These materials are generally very important for medical purposes, especially in the reconstruction and replacement of bone material. For medical applications, inert, bioactive or bioresorbable materials can be used. One of the common "bioactive" materials is hydroxyapatite, which forms a large part of human bone. Hydroxyapatite can be prepared by a wide variety of procedures, one of the most common methods is the precipitation reaction used in this work. To improve the biocompatibility of the bone replacement, porous structures with adequate mechanical stability are used. For the initial study of simulation of the behavior of biomaterials in the human body, called in vitro tests are used in solutions based on synthetic body fluids or cell media. The experimental part deals with the synthesis of hydroxyapatite powder and CA phase composite compounds. The reactions between the individual components were studied by thermal analysis and heat microscopy. The resulting products were analyzed for phase composition by X-ray diffraction. The prepared powders were further processed on foam structures by in situ foaming and sintering at a suitable temperature. In vitro tests, following the behavior of the prepared porous products in the synthetic body fluid, were performed for 7, 14 and 28 days. The monitored composites were then studied for biocompatibility by scanning electron microscopy. At the same time, the change in the concentration of Ca2+ and PO43- ions in the body fluids tested was monitored.

This diploma thesis is concerned with the stress analysis of the total hip joint endoprosthesis ceramic head under oblique loading. Load was obtain from experimental in vivo measurement on three patients, whereas two of them was the same weight. As input variables were use contact forces, especially knee bend and standing on one leg. Furthermore they will be considered shape deflections from ideal cone, especially circle deviation, cone deviation and cone plus circle deviation together.

This diploma thesis deals with probability of fracture ceramic head of total hip endoprosthesis during tests by the standard ISO 7206-5. In the first part is made stress analysis with method of finite elements in program ANSYS. Six types of ceramic head with different geometry was analysed for ideal geometry of head and shaft, and also for shape imperfections from nominal conical shaft and head. The final values of principal stress from stress analysis were entry values for the second part – probability of fracture analysis. Weibull weakest-link theory was applied, namely 3-Parameter and 2-Parameter Weibull distribution.

The thesis is in the first part focuses on the description of the technology and tumbling overview of the applications in which it is possible to use this technology. This topic is the description tumbling wet using ceramic beads. In the third part of this work is performed a brief overview of the types of tumbling machines. The following is a list of their own design variant tumbling machine with a choice of optimal design variants. Then follows the design of the tumbling machines, followed by an overview of the calculations. In the last part of this work are the technical parameters of the designed tools, including a description of its operation and maintenance.

This thesis contains an introduction to astrology and zodiac in theoretical part. It represent zodiac during the art history and discusses its symbolic meaning as a whole and its individual signs. Furthermore, affects the issue of language art forms in the psychology of art. The practical part of thesis is focused on objects realization, they result from combination of shape elements and importance of astrological signs. The outcome of this part of work is set of 12 ceramic objects.

The Diploma thesis introduces the luminars as the creative objects importing the light into our homes and effecting our mood. The objects are modeled of the slurry combined with glass. These are determined to the installation on the table, floor, wall and ceiling. For the shape I was inspired by MICROCOSM = a world of unicellular living being, before all by the protozoans. It is a world full of bizar structures and shapes. The simplicity and expediency of the protozoans offers the inexhaustible amount of ideas. Each of the objects has got its adumbrating image in some of the protozoans. Teir shapes, determination of kind, conditions, in which they live, were determinating the luminars´ visage. Although the inspiring source is stating them the individual luminars presents original, solitary objects.

This thesis deals with the issue of collection of ceramic solitary dishes, which are decorated with colour pigments with landscape motives. Five individual objects, variable in shape, which form one complete set. These are five records of floodplain landscape, vineyards and fluvial forests. This thesis aims at connection between wall painting and ceramic material, connection of utility and free creation. The introduction is devoted to the theoretical knowledge; the second part develops technological and practical skills.

The Krasno deposit is only one active mine at Slavkovsky les. Mined are feldspars raw materials with high quality, commonly used in ceramic and glass industry. Mined raw material has a lot of additional components, which has influence on quality of raw material. Main additional components are unwanted coloring Fe oxides. Another additional components are apatite and topaz, which dont have influence on quality of raw material. The most interesting additional components of raw material are Ta - Nb, Li - Rb minerals. Currently the processing of raw material is under modernization for maximal separation high quality of feldspar material. The result of semi-processing operation shows the concentrate can be potential source of strategic raw materials as Nb - Ta or Li - Rb mineralization. For separation of these minerals and elements must be realized detailed research of selected processing and properties of these minerals. Powered by TCPDF (www.tcpdf.org)

The thesis is concerned with creating of a computational model of open-cell ceramic foam and determining mechanical properties of open-cell ceramic foam using computational modeling. The geometry of Kelvin cell was used for creating the model of geometry of the foam. The model of geometry of ceramic foam structure was meshed with solid elements, with beam elements and with combination of rigid beam and beam elements. Elastic properties of the foam were determined by two types of mechanical loading. Young´s modulus and Poisson´s ratio were determined by tensile/compressive mechanical loading and shear modulus was determined by shear mechanical loading. The relationship between mechanical properties of the foam and the ratio of diameter of strut D and length of strut L was analysed in the thesis. A good agreement was found out between Young´s modulus determined by solid element based and Young´s modulus determined by modified beam based model of geometry of the foam structure – for ratio D/L up to 0,6. In the case of Poisson´s ratio a good agreement was determined up to D/L = 0,4. In conclusion the value of Young´s modulus 1,97 GPa which was determined by computational modeling was compared with the value 1,56 GPa which was determined experimentally on ceramic foam. This difference was caused by idealization of geometry of the real ceramic foam material. In addition, mechanical properties of the ceramic foam material are influenced by structural imperfections of the material.
