Fire station, Chrudim
Bezdička, Petr ; Müllerová, Eva (referee) ; Müller, Jan (advisor)
The subject of the thesis is the elaboration of the design documentation for the execution of the fire station. The fire station building will be used for continuous performance of the fire protection units of the Fire and Rescue Service of the Czech Republic for the Pardubice region. The proposed fire station building is divided into two operational units. The first part is administrative, two storey. The second part is the ground floor part of the garage stalls, service and car wash, along with the necessary warehouses. The two units are operationally linked. The construction system of the building is wall made of ceramic masonry in part of the administration, the roof structure is designed as a single-sheathed flat roof. The cladding is done from a certified contact cladding system. The second part of the object consists of a steel skeleton with truss ties. The sheathing, both horizontal and vertical, is made up of sandwich panels.

Apartment building, Chrudim
Bezdička, Petr ; Galata, Jindřich (referee) ; Müller, Jan (advisor)
The bachelor's thesis deals with the design of a new-build apartment building located in the town of Chrudim. The apartment building is designed as a detached. The building has three above ground floors and a partial basement. The entrance to the building is from the southeast side. There are 12 residential units in the apartment building, 4 units on each floor in sizes 1+KK, 2+KK and 3+KK. The flats on the second and third floors have a balcony facing either the southwest or northeastes. The apartment building is designed using Porotherm technology with a contact insulation system. The horizontal structures are designed as a reinforced concrete monolithic ceiling structure. The roofing is designed as walkable flat roof.

Noninvasive spot analysis of miniatures with portable and laboratory instruments: a methodology for specific use in miniature painting research
Kočí, Eva ; Bezdička, Petr ; Hradil, David ; Garrappa, Silvia ; Hradilová, J. ; Pech, M.
The methodology brings a comprehensive procedure of non-invasive materials analysis of painted miniature artworks, while it is divided into two subsequent parts. In the first part, it describes the use of portable devices for spectroscopic analysis of miniatures, and in the second, it deals with the application of a new methodological procedure for phase/structural materials analysis based on X-ray powder diffraction. The methodology thus includes the following procedures: (i) determination of the elemental composition of the colour layer by the x-ray fluorescence analysis, (ii) identification of binders and other organic compounds using infrared spectroscopy (FT-IR), and finally (iii) phase/mineralogical and structural analysis to describe in more detail the pigments used and processes of their degradation. As part of this last step, the limits of Raman spectroscopy (RS) and the advantages of powder X-ray diffraction and micro-diffraction (XRPD and micro-XRPD) are described, which include greater gentleness to the analysed objects. A very complete and above all non-invasive methodological procedure for the analysis of miniatures is thus offered, which uses the complementarity of individual methods and which can be partly applied already in situ (directly in collection institutions) and partly at specialized workplaces.

Lead soaps in paintings: symptoms and the role of humidity
Garrappa, Silvia ; Švarcová, Silvie ; Kočí, Eva ; Hradilová, J. ; Bezdička, Petr ; Hradil, David
In this study, an overview of the symptoms of lead soaps reported in artworks in combination\nwith the study of the role of humidity on the formation of these degradation products have\nbeen thoroughly investigated. The use of optical microscopy, scanning electron microscopy\n(SEM) in combination with Fourier-transform infrared spectroscopy (FTIR) proved to be an\nefficient analytical approach to highlight both the saponified area of artworks’ samples and the\nformation of metal carboxylates within mock-up model systems. Optical microscopy revealed\nto be very useful for the first screening of samples embedded in resin, while SEM helped in\nthe detection and distribution of elements within the cross-sections. On the other hand, FTIR\nmicroscope proved to be a very powerful instrument for high-resolution point measurements\nperformed in the attenuated total reflection mode (ATR) mode with mercury-cadmium-telluride\n(MCT) detector, as well as for chemical imaging of larger area of both artworks’ and mock-up\nsamples performed in the ATR mode with focal plane arrays (FPA) detector. This study provides\nnew useful insights contributing to better understanding of factors affecting the paints‘ stability,\nwhich is neccesary for developing new efficient strategies for preservation and restoration of\nfatty-based painted artworks.

Rebecca and Eliezer at the well a mysterious oil painting from the Historical Museum of the Slovak National Museum at the Bratislava Castle
Hradilová, J. ; Kližanová, H. ; Bezák, M. ; Holcová, K. ; Bezdička, Petr
Light microscopy, scanning electron microscopy and microanalysis, X-ray powder micro-diffraction, infrared micro-spectrometry as well as palaeontological analysis have been applied in order to solve the question of provenance of the oil-on-canvas painting Rebecca and Eliezer at the well. In addition to the finding of pigments important for the dating of the painting, as, e.g. Naples yellow (Pb2Sb2O7), or smalt, fossil nannoplankton was described in the carbonate-rich clay ground. It indicates the use of marine sediments of Eocene to Oligocene age. According to mineralogical and paleontological data this ground may be included among grounds used in Italy, particularly in the 17th century. The studied painting is today greatly altered due to extensive reworkings. Prussian blue was used to overpaint faded ultramarine and degraded smalt, which is visibly affected by saponification processes.

IR Laser CVD OF Nanodisperse Ge-Si-Sn Alloys Obtained by Dielectric Breakdown of GeH4/SiH4/SnH4 Mixtures
Křenek, Tomáš ; Bezdička, Petr ; Murafa, Nataliya ; Šubrt, Jan ; Pola, Josef
Nowadays, great attention is devoted to Ge-Si-Sn ternary system, because Si1-x-yGexSny provides the potential of band gap engineering and tuning of the optical properties. IR laser irradiation of equimolar gaseous GeH4 + SiH4 + SnH4 + Ar mixture results in simultaneous decomposition of all three compounds and it allows deposition of nanostructured solid film. Analysis of the films by FTIR and Raman spectroscopy, X-ray diffraction analysis and electron microscopy revealed crystalline nanobodies of pure beta-Sn and crystalline nanoobjects of Ge1-x-ySixSny embedded in an amorphous metastable Ge-Si-Sn alloy. This process allows co-decomposition of all silicon, germanium and tin hydrides which is caused by combination of infrared multiple photon dissociation of absorbing silane and currently proceeding LIDB. This is followed by intermixing/clustering of extruded metal atoms in the gas phase.

The effects of artificial ageining on model colour layeres containing neutral verdigris
Bauerová, P. ; Bezdička, Petr
Verdigris belongs to traditional painting pigments. In artworks it most often occurs in combination with lead-tin yellow or lead white. However, its colour is considered unstable. The aim of this study was to find out which conditions contribute to colour changes of the most frequently used neutral verdigris (hoganite) Cu(CH3COO)2.H2O and whether these changes happened as a result of the assumed verdigris-binder interactions or caused by the degradation of the pigment itself. The article summarises first results of artificial ageing experiments.
