Electrochemical Study of Osmium Tetroxide Comptests Reactivity to DNA Bearing Butylacrylate
Havran, Luděk ; Havranová-Vidláková, Pavlína ; Špaček, Jan ; Vítová, Lada ; Hermanová, Monika ; Fojta, Miroslav
Coniplexes of osmium tetroside with nitrogen ligands (Os,L e.g.. with 2,2'-bipyridine (bpy) find application in redox labelling of DNA.. probing of DNA structure, and in studies of DNA interaction with other molecules Os,L preferentially react with pyrimidines in single strand DNA producing electroactive adducts Primary reaction site for Os,L is C=C double bond in pyrimidine nucleobases. In this contribution we introduce a new two-step technique of DNA modification with Os,bpy, consisting in enzymatic construdion or DNA beating butyl acrylate (BA) moieties attached to uracil or T-deaza adenine, followed by chemical modification of a reactive C=C double bond in BA residue.

Safety inspections in region Vysocina
Špaček, Jan ; Radimský, Michal (referee) ; Matuszková, Radka (advisor)
This thesis presents a safety inspection in selected places in the Vysocina region of the Czech Republic. Six intersections in rural and municipal areas, plus three rural road sections were selected for the inspection and an accident rate analysis. The places selected were compared in terms of the accident rate and one case of each group was then selected for a detailed safety inspection encompassing visual inspection and identification of possible hazards. By eliminating such safety hazards, it is possible to ensure a traffic fluency and to preclude traffic accidents or at least minimize the harm caused by it.

Bass string instruments used in church and folk music in Prague and central Bohemia
Špaček, Jan ; ŽALUD, Radomír (advisor) ; HUDEC, Jiří (referee)
This thesis is aiming to summarize and compare instruments used in church and folk music in Prague and central Bohemia. At first it names various types
of instruments and describes their characteristics. Then pick few makers
who influenced development and expansion of double bass in the land, and following
with pick of particular instruments and their description.
Last part of this thesis speaks of Ondrej Hornik and his collection, which
is valuable source of information and tangible documentation of musical development in Czechia.
Included is an insert located at the end of this work.

Integration of the Corona renderer into the ArchiCAD software
Špaček, Jan ; Křivánek, Jaroslav (advisor) ; Vévoda, Petr (referee)
Integration of the Corona renderer into the ArchiCAD software Bachelor thesis - Jan Špaček, 2018 We present a prototype of a plug-in that integrates Corona Renderer into Archi- CAD. We strive to make Corona in ArchiCAD as easy to use as in other graphics applications, so the user interface is a major concern in our plug-in. Special focus was given to interactive rendering, which has proved to be a technical challenge in other host applications. We give a brief overview of the APIs that we use and describe the architecture and implementation of the plug-in. We also present the performance of interactive rendering on various scenes. 1

Audio D/A converter with external control using microcontroller
Špaček, Jan ; Stifter,, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This diploma thesis deals with the design of a laboratory measurement tool with ADC converter for audio and low frequency signals. In the introduction part a theoretical background of the ADC and DAC conversions are outlined. In the next chapters the technical solution of the laboratory converter is presented, including DAC with integrated circuit AD1852 and completed with digital audio receiver CS8416. This circuit secures compatibility with external audio devices with digital interfaces, like SPDIF or AES3. The digital receiver and audio DAC are added with serial communication interface for setup of the most audio and input parameters. This setup is operated by external microcontroller ATmega32 and original firmware. The thesis contains block diagram and schematic layout of the laboratory converter, including complete technical documentation for the construction and design.

Design of urban area using advanced technologies
Špaček, Jan ; Apeltauer, Tomáš (referee) ; Remeš, Josef (advisor)
This thesis focuses on the design of urban areas in regards of the air flow and the creation of Urban Heat Islands. It reviews basic aspects influencing the design of streets. Every building, tree, or obstacle obstructs the air flow and creates the wind shadow, where the air pollution increases. It also creates areas of higher wind speed, in which public comfort is reduced. By understanding the importance of this process and by implementing it into the urban planning process, using advanced technology we can create healthy urban environment.

Outreach work with drug users - foreigners
Špaček, Jan ; Vrzáček, Petr (advisor) ; Janíková, Barbora (referee)
The diploma thesis is aimed to improvement work of outreach drug workers who works with drug addicted people from foregin countries in Prague. The theoretical part od diploma thesis briefly describes legislative framework linked with use of illicted drugs in the Czech Republic, Drug Strategy of the Czech Republic and definiton of therm street work in the Social Services Act. Next part of the thesis focused to information from lately situation on the open drug market in Prague a nd describes period, since when has been in touch outreach workers and drug addicted people from foregin countries. Thesis further comparing approaches to drug policy in countries of orign drug of drug addicted foreginers at Prague. As well deliberately select in each country important topics for outreach work. The methods used to obtain the necessary information included document analysis, observation, structured interviews and focus group. Information was collected to help in face to face work with drug users. To better understand the environment from which drug users - foreigners come from. Which services can they know from their home country, what services drug users - foreigners can use in the Czech Republic and how to work better with this target group. And also what measures can help Czech outreach workers. Based on...

Libretti by Lorenzo Da Ponte
Špaček, Jan ; Pelán, Jiří (advisor) ; Žáčková, Magdalena (referee)
The theme of the bachelor thesis is Italian libretti by the poet Lorenzo da Ponte. The thesis is dealing with a bio-bibliographical aspect of the author, analyses of three opera libretti and characteristics of texts written by da Ponte with a brief comparison with the work of the Italian poet and librettist Pietro Metastasio. Italian libretti are divided into three main chapters: Le nozze di Figaro, Il dissoluto punito ossia il don Giovanni and Così fan tutte ossia la scuola degli amanti. In individual parts descriptions are divided into a separate analysis of the above mentioned opera libretti. Introduction of each chapter describes a specific work and circumstances of its creation. A more detailed analysis aims to describe prominent figures and their possible changes in the course of the plot, analyze rhythm in stanzas and identify specific phrases, metaphors and naming. Conclusion of each chapter ends with the most important findings and the potential anomalies, which were discovered during the analysis.

Colonisation of Central Europe by benthic frehwater crustacean Asellus aquaticus (Isopoda, Crustacea)
Střížek, Antonín ; Sacherová, Veronika (advisor) ; Špaček, Jan (referee)
Longterm climate changes are an inseparable part of the evolution of Earth. In the last few milions of years the changing of glacials and interglacials was as ordinary and regular phenomenon as changing from day to night or from spring to summer. These cycles also have similar influance on evolution of nature on Earth. Eventhough the state of nature appears to us stable for the few last human generations, the reality from the long term point of view is differnt. During these cycles, the location of climatic zones, size of glaciers, deserts, savannahs, steppes or rainforests have changed. Organisms changed locations of their areas of distribution, many nowadays widespread species were pushed into isolated local populations. This Master's thesis reveals the impact of glacial cycles on a freshwater crustacean aquatic Isopod (Asellus aquaticus). Very variable mitochondrial COI gene was sequenced within 139 individuals of this species from 62 different localities in Europe. This data were included into an extensive scope of an already known phylogeographic structure of the continent. An Aquatic Sowbug shows a quite high rate of a genetic heterogenity (maximum Nucleotide Divergence discovered is 0,132 and average is 0,016) in the area of the Czech Republic. Where there are found representatives of two...
