Renovation of the castle in Velké Němčice
Malínková, Valerie ; Muroň, Ivo (referee) ; Ležatka, Lukáš (advisor)
This bachelor thesis deals with the restoration of a castle in Velké Němčice. The thesis builds on an architectural study carried out in the AG033 course of the Restoration of Monuments Studio. The task of the thesis is to create a complete project for the appropriate restoration and reconstruction of the castle and to propose its new utilization. At the same time, the thesis focuses on the solution of the castle's immediate surroundings. The object of the solution will be designed as a socially cultural object with administrative functions. The castle should serve as a new town hall, and in accordance with this, the following rooms will be created in the castle: a ceremonial hall, information center, mayor's office, secretary's office, registry office, accountant's office, archive, library, club room, refreshment facility, and interactive room. To achieve the implementation of the new operation in the castle, the correct restoration of the historical object is necessary. Using surveys and historical sources, I examine the architectural values and construction of the building. I strive to preserve historically significant layers, remove intrusive modern elements, and return the object its original expression. With the help of new technologies, I also strive to preserve the building for future generations. I propose minimum use of modern structures and elements, and therefore mainly focus on proper reconstruction and restoration.

Brno City Hospital
Seďa, Ondřej ; Hybská, Bohumila (referee) ; Sedláček, Michal (advisor)
The topic of the diploma thesis is the design of a town hospital at Kraví hora in Brno. The design of the new city hospital in Brno replaces the functions of two existing city hospitals, the Merciful Brothers Hospital and the Trauma Hospital, whose technologies do not meet the medical requirements of the 21st century. In the hospital there are standard facilities, namely outpatient medical facilities, including day hospitals, central blood collection, emergency, operating rooms, central sterilization, anesthesiology and resuscitation departments, intensive care units, maternity and neonatology departments, examination complement , laboratories, rehabilitation departments, inpatient departments of surgical and internal medicine, non - medical and commercial premises, personnel background, technical background and parking. The hospital is a 10-storey building. The main idea of the design was to create a hospital with the views of the park even Brno skyline.

Sandstone moisture measurement: laboratory and field techniques
Sommerová, Anna ; Bruthans, Jiří (advisor) ; Schweigstillová, Jana (referee)
Summary: In my thesis I reviewed the most used methods for moisture measurements with the focus on sandstone exposures. Concerning direct methods, the gravimetric is used most commonly for the calibration of other methods. Concerning indirect methods I mention radiometric, microwave, resistive and capacity methods. The major part of thesis is dedicated to capacity device TDR (Time Domain Reflektometry), which emits electromagnetics pulses and measures the reflection time at the beginning and the end of the probe. This methodology is nondestructive and is widely used, mainly in pedology. In practical part of Theses I worked with drill cores of sandstone from natural exposures and I detected their mass water content using gravimetric method, their bulk density by laboratory measurements and from those values I calculated volumetric water content. Average value from measured mass water content is 3,3% and from volumetric water content 6,2%. At some localities the moisture content was measured by TDR was measured beside taking drill cores At places where it was possible to compare measurements using TDR with gravimetric method, TDR measurements show usually higher values (in average 1% higher) then gravimetric method. This fact is caused by calibration and accuracy of the device, generally though this TDR...

Permeability of natural surfaces of Hruba Skala sandstone in rock cities for water vapour and intensity of evaporation
Slavík, Martin ; Bruthans, Jiří (advisor) ; Pavlíková, Milena (referee)
Aim of this study was to describe capillary water and vapor transport in shallow subsurface of Hrubá Skála sandstone in the Bohemian Paradise. I have quantified permeability of Hrubá Skála sandstone for water vapor using "wet cup" method and also capillary water absorption of sandstone drill cores. I have found out general rules of evaporation and rate of evaporation from several sandstone outcrops in real microclimate. Important part of my work was to determine whether surface crust plays some role in studied parameters. Based on my results, permeability of different types of sandstones for water vapor does not vary significantly and surface crust has no effect on rate of water vapor diffusion. Rate of capillary water absorption is reduced by surface crust. Hrubá Skála sandstone is classified as medium or highly absorbing material. I have proved that evaporation from porous medium can be approximated by exponential function. Rate of evaporation is strongly controlled by climatic conditions, especially by relative humidity.

Channels eroded by groundwater flow in Strelec quarry: erosion processes and factors influencing channel evolution
Soukup, Jan ; Bruthans, Jiří (advisor) ; Grmela, Arnošt (referee)
Large depression cone in water table was formed due to mining in surroundings of Střeleč quarry. The concentrated inflow from conduits to quarry is up to 70 l/s. Large conduit systems are created by flowing water into the quarry. The biggest conduit system was at least 300 m long and 17 m high with maximum calculated volume of 22 thousands m3 . Evolution of these conduits usually takes several months to few years. Fast conduit evolution allows to study erosion processes in detail in situ. In the thesis I am describing conduits, character of flow and erosion processes. Measured flow velocities in conduits are up to 0,4 m/s with hydraulic gradient 1 to 5%. Flow velocities and hydraulic gradients are typical for piping erosion. Piping initially forms small protoconduits. The bigger conduits are formed as water is progressively drained from larger area. Conduits are following fracture surfaces, which are also limiting the conduit propagation to the sides. Above water table the conduits are enlarged mainly by mass wasting of undercut sandstone slabs. For distinguishing less and more erodible parts of sandstone, we adapted and partially developed a method for measuring erodability (REI) and drilling resistance (DR). Both are used to compare different types of sandstone surfaces. In lowermost part of the...

Permeability of sandstone surfaces and water flow in shallow zone of ruiniform sandstone landscape
Sysel, Ondřej ; Slavík, Martin (advisor) ; Tesař, Miroslav (referee)
Water in porous rocks (e.g. sandstone) plays a fundamental role in their disintegration. However, the places where water enters the sandstone rocks are somewhat overlooked. At two sites in the Český ráj region, I use Karsten tube to measure capillary water absorption (CWA) of natural sandstone exposures and, using TDR (Time Domain Reflectometry) method, I study movement of water in a shallow zone of ruiniform sandstone landscape. The CWA differed up to four orders of magnitude at a distance of tens of meters, mostly depending on the type of the surface. The highest CWA was measured at highly weathered surfaces, the second most absorbent were less weathered surfaces covered with a biologically-initiated rock crust. The horizontal surfaces on the tops of the rock formations were even less absorbent, probably due to clogging by fine particles from soil. Surfaces covered with iron crust were the least absorbent. The differences between those surfaces are significant. After simulated infiltration, the maximum rate of the propagation of the wet front in the sandstone was from 5,5.10-6 do 1,9.10-4 m.s-1 measured by TDR. The water propagated at this rate only to a certain depth (the first tens of cm), but then the propagation stopped or slowed down rapidly. From a long-term measurement of volumetric...

Isotope alteration of carbonate component of Cretaceous sediments from xenolites and vicinity of selected neovolcanic bodies of the Jičín volcanic field
Konečný, Tomáš ; Zachariáš, Jiří (advisor) ; Trubač, Jakub (referee)
The diploma thesis deals with the study of stable isotopes of oxygen and carbon of Cretaceous rocks from the Jičín volcanic field. The aim of the thesis is to identify isotope alterations in Cretaceous sediments transported by basic magmas in the form of xenoliths and to determine the origin of oxygen and carbon of hydrothermal vein carbonates that penetrate the bodies of neovolcanites. The study is divided into two parts. The theoretical part summarizes in general the stratigraphy of the Czech Cretaceous Basin and Cenozoic volcanism of the Bohemian Massif, geochemistry of stable isotopes of oxygen and carbon and geology of studied localities in the Jičín volcanic field. The practical part presents a detailed isotope study of Hřídelec, Kulatý vrch, Zebín, Veliš and Kunětická hora localities. Cretaceous rocks from xenoliths in these neovolcanites show extreme variability in the isotopic composition of both carbon (from 0,15 to -11,1 ‰ V-PDB) and oxygen (from -5,4 to -22,9 ‰ V-PDB). They significantly exceed the variability of the isotopic composition of diagenetically altered Cretaceous rocks from the same area. The wide range of oxygen isotope composition is the result mainly of fluid temperature variability (approx. 300 - 20 řC), which isotopically altered Cretaceous sediments. Carbon isotope...
