1. Reconstruction of the vocational school Dubňany. Construction Technology Preparation
Dohnálek, Marek ; Hrůza,, Jaroslav (referee) ; Kovářová, Barbora (advisor)
The subject of this technological preparation of construction is to find out scope of work needed for reconstruction of former miners school in Dubňany.In Czech Republic exits plenty of these abandoned places and this master thesis should serve as an example of reconstruction of some theirs parts.Within this project I would like to valorize the experience gained from excursion to foreign countries, where the passive and low-energetic buildings are common.Missing project documentation of some part of this facility was replaced by 3D modelling based on my own laser measurement.The main object SO 01 has been already rebuilt into passive apartment building but without building-technological study and proper project documentation.Due to missing foundations and confidential internal documentation of the construction company is impossible to compare the real material, human and financial resources with those mentioned within this thesis. The master thesis contains technical report for the building-technological project, coordination of the transport routes, chronological and financial plan, realisation of the main technological steps, equipment of the construction project , draft of machinery, time schedule of the main project, plan of getting the needful resources, technological regulations, control and probationary plans, disposal of asbestos reports, owning contract, two roof decks comparison from the point of view of thermal technology and specialization from the building field.

Recycled aggregate to pavement constructions of roads
Antošová, Klára ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The diploma thesis deals with using of recycled aggregate of concrete for base layers of pavement. The work is divided into practical and theoretical part. The theoretical part deals with basic concepts of construction and demolition waste, production, development and management of this waste in the Czech Republic. It also focuses on the principle of recycling and the use of recycled concrete in the Czech Republic and abroad. The practical part of the thesis deals with laboratory testing and assessment of recycled aggregates in bound, unbound and grouted courses layers of the base layers of roads.

Studium vzniku sekundárních částic z plynných prekurzorů a jejich podílu na celkové imisní zátěži: Toxikologicky závažné kovy v emisích a jejich podíl na tvorbě sekundárních částic
EGÚ Praha Engineering, a.s., Praha ; Fara, Milan
Studie se zabývá vlastnostmi těžkých kovů vzhledem k jejich vstupu do organismů a škodlivým účinkům. Jsou uvedeny vstupy těžkých kovů do životního prostředí, přírodní a antropogenní zdroje emisí těžkých kovů a je diskutována esencialita těžkých kovů. Podrobně jsou uvedeny toxické vlastnosti olova, kadmia, rtuti, arsenu, mědi, chromu, niklu, selenu a zinku, což jsou kovy sledované v emisích a reportované podle mezinárodních dohod. Jsou diskutovány spalovací procesy jako zdroj emisí těžkých kovů a schopnost kovů účastnit se reakcí s jinými částicemi nebo radikály podle fyzikálně chemických vlastností prostředí. Z transformačních procesů těžkých kovů v životním prostředí a v atmosféře zvlášť je zdůrazněn pohyb rtuti, která vykazuje vysokou mobilitu díky své plynné formě. Rámcově jsou uvedeny technické prostředky k omezování emisí těžkých kovů. Jsou diskutovány emise těžkých kovů a tuhých částic ve vybraných aktivitních sektorech a jsou uvedeny emisní faktory. Pozornost je věnována i emisím prachu a sekundární prašnosti, včetně emisí asbestu a umělých minerálních vláken, emisí ze skládek tuhých odpadů a sektoru dopravy.

Ověření obsahu azbestu v horninách lomu Sýkořice : závěrečná zpráva
Skála, Roman
Zpráva je volně šiřitelná. Anotace: U pěti vzorků hornin z lomu v Sýkořici byl vyhodnocován možný obsah azbestu. Horniny byly podrobeny makroskopickému a mikroskopickému pozorování a studiu elektronovým mikroanalyzátorem a práškovou rentgenovou difrakcí. V žádném ze studovaných vzorků nebyly nalezeny významné akumulace azbestových minerálů, jak jsou definovány právními normami ČR.

Issues of asbestos exposition in agricultural brownfield sites
Bartoň, Roman ; Hadrabová, Alena (advisor) ; Dvořák, Antonín (referee)
This diploma thesis deals with issue of agriculture brownfields with exposure of asbestos. First part introduces asbestos, it's properties, history, health risks, important legal standards and rules for handling of asbestos waste. Next part includes introduction to brownfields issue. Topic of the agricultural brownfields is connected with asbestos issue. Reader will get the information about brownfields, its definition, categorization and impact on the site. Later on there will be information about financing of brownfields revitalization. Practical party of the thesis is oriented to problem with one concrete brownfield -- former poultry farm in Kotopeky. I describe the history, current status, potential future use and possibilities of financing the revitalization. Last part of this diploma thesis is filled with the manual for people who want to remove asbestos roof on their own.

Health risks related to occupational exposure to asbestos
KLIMKOVÁ, Lenka
In our republic, occupational exposure to asbestos has been restricted to jobs concerned with disposal of products, materials and buildings containing asbestos, and research work studying asbestos fibres. The reason consists in health risks as all kinds of asbestos belong to high-risk carcinogens. The asbestos fibre related diseases should be reported. All data connected are kept in the National Institute of Public Health (NIPH) in Prague. The purpose of this study was to find out how much people are aware of the risks related to asbestos and find people who suffered from asbestos dust-induced disease, i.e. mesothelioma of pleura. The quantitative method was used to summarise information on asbestos-induced disease occurence in 1970-2010 available in the National Institute of Public Health in Prague. Along with that, the work maps the population awareness of asbestos risks. The thesis itself can be divided into two parts. The first one contains information based on data collection while the other part deals with data of NIPH in Prague. Two hypotheses were predicted: Hypothesis H1: People are aware of the material containing asbestos. Hypothesis H2: People are aware of negative impact of asbestos on human health. Both hypotheses were proved. Three hypotheses were suggested in the other part: Hypothesis H3: Latency, the time between first exposure to manifestation of disease, is never less than 20 years. Hypothesis H4: Incidence of mesothelioma of pleura and peritoneum is higher in people aged 60-69. Hypothesis H5: Smoking affects the course of the disease negatively. Hypotheses H3 and H4 were proved. Hypothesis H5 cannot be neither proved or disproved. Although the number of smokers among mesothelioma patients was higher, there is no evidence of negative effect of smoking on the disease. To prove this hypothesis, the data colllection should be larger. Findings of the study proved the time of exposure to asbestos fibres does not affect the occurence of this disease. The findings can be used in further research studies.
