Risk of stationary sources associated with valuation of environmental damage
Procházková, Michaela ; Popelová, Barbora (referee) ; Adamec, Vladimír (advisor)
The problems with the environmental damage valuation which are caused by the stationary sources belong to the important issues to be solved. Due to the heavy industrial activity in the Czech Republic it is important to pay attention to the possible risks which can emerge from these sources and can impact the environment and the health condition of people. The thesis deals with the analysis of the present state of this problem. The analysis of the risks which come from the specific situation is made on its basis. The goal of this thesis is to propose the general procedure of the valuation of the incurred damage on the environment and the minimization of the risks.

Exposure to Nanoparticles in Work Environment
Köbölová, Klaudia ; Mikuška, Pavel (referee) ; Adamec, Vladimír (advisor)
Outside to the wide range of potential benefits, the use of nanomaterials can endanger human health and the environment. This diploma thesis presents the results of pilot measurements, where the exposure of nanoparticles was monitored. Based on a literature research a suitable method for measurement was the three-stage OECD model. Based on this model, measurements were performed in three welding workplaces, where nanoparticles are produced incidentally. The measurement consisted of collecting information and measuring the concentration of nanoparticles in the workplace, where data collection was focused only on inhalation exposure. During welding, 0.3 m size particles are produced and their concentration is strongly influenced by the welding material, type of welding and suction. The particles are amorphous in terms of morphology and contain manganese, iron and silicon, which can cause neurodegenerative diseases. Furthermore, the results indicate the importance of monitoring oral exposure.

Analysis of Critical Points in the Transportation of Hazardous Substances by Road
Fidrichová, Ivana ; Dostál, Ivo (referee) ; Adamec, Vladimír (advisor)
Diploma thesis focuses on the analysis of critical points in the transport of hazardous materials on the basis of which there is given a methodology for selecting safe routes. Thethesis includes statistical data on the total performance in the transport of hazardous materials within the EU states as well as specifies the proportion of transport performance of hazardous materials to the total performance among the individual European countries. For Czech Republic, the thesis also presents a statistical overview of the accident rate associated with this kind of transport as well as deals with the causes and consequences of the accidents occured during the transportation.

Safety Management System for Transport of Materials and Dangerous Substances
Klímová, Zdeňka ; Krejčí, Libor (referee) ; Adamec, Vladimír (advisor)
The task this master’s thesis was evaluated present status safety management system for transport of materials and dangerous substances. I looks this issues like whole in The theoretical part. I want to find all kritical locations. I analysis type of transport, transport routs, driver training, legislation and label the most transport of materials and dangerous substances. I want to found the risk to remove or cushion. I want to proposed preventive measures in the practical part.

Risk Managament in Project Management
Řezníček, Zbyněk ; Adamec, Vladimír (referee) ; Kruliš, Jiří (advisor)
The diploma thesis deals with the issue of risk management in project management. It focuses on a project that describes a change in the holiday process and introduces a motivation system for employees. The thesis is divided into three parts. The first part describes the theoretical basis based on professional literature. The analytical part describes the current state of the process, the company and identifies the risks. The draft section proposes measures to reduce the risks in the project, and recommendations are made to increase the likelihood of adopting the proposed changes.

Effect of ESP on distribution and chemical composition of particles from biomass combustion
Preisler, Lukáš ; Köbölová, Klaudie (referee) ; Adamec, Vladimír (advisor)
Biomass combustion causes a significant number of particles that, released into the atmosphere, negatively affect human health. Knowledge of the size and composition of the particles is essential for possible flue gas separation by electrostatic precipitation technology. This technology is developed and used in large power plants, but the electrostatic precipitation in domestic boilers is rare. This work describes the methods of fine particle formation and their size distribution and composition. Measurement methods of chemical composition and the size distribution are provided. According to a review, the effect of electrostatic precipitator on size distribution and chemical composition is discussed. In the experimental part, fine particles were sampled from the flue gas of a domestic wood pellet boiler containing an experimental electrostatic precipitator. Due to operational reasons, the electrostatic precipitator did not run during sampling. Flue gas condensed on the inner surface of the flue. The particles were sampled on filters at the beginning and the end of the flue. The filter was analyzed on an electron microscope.

In Vitro Study of the Effect of Particle Characteristics and Flow Rate on Regional Deposition in Human Airways
Bělka, Miloslav ; Adamec, Vladimír (referee) ; Farkas, Árpád (referee) ; Jedelský, Jan (advisor)
Dlouhodobé vdechování částic může přispívat ke vzniku nebo zhoršení nejrůznějších plicních onemocnění. Na druhou stranu, vdechování léčiv je často používanou metodou podávání léků proti astmatu a jiným nemocem dýchacího ústrojí. V obou případech je důležité dobře porozumět mechanismům, na jejichž základě funguje pohyb částic a jejich usazování v dýchacích cestách. Cílem této disertační práce bylo získat nová experimentální data depozice částic a analyzovat vliv tvaru částic a průtoku vzduchu na depozici. Byla studována depozice porézních a vláknitých částic v realistickém modelu dýchacích cest. Porézní částice byly vyrobeny různými metodami, např. sprejovým sušením nebo metodou krystalizace. Takto vyrobené částice byly použity při depozičních experimentech. Detekce částic byla provedena pomocí UV/VIS spektrofotometrie. Vláknitý aerosol byl vytvořen rozdrcením skelné vaty. Takto vzniklé vláknité částice byly několikrát prosety přes řadu sít a dále roztříděny podle délky pomocí klasifikátoru pracujícím na principu dielektroforézy. Následná depozice byla vyhodnocena použitím mikroskopie s fázovým kontrastem. Ke zrychlení analýzy byl vyvinut program, který dokáže na základě analýzy obrazu najít a spočítat vlákna. Výsledky experimentu byly použity k určení depozičních charakteristik. S jejich pomocí pak byl kvantifikován vliv tvaru částic a průtoku na míru usazování. Depoziční účinnost částic rostla v závislosti na Stokesově čísle, což poukazuje na vliv setrvačnosti při usazování částic. Bylo prokázáno, že depoziční účinnost porézních částic je podobná té u částic kulových při stejném Stokesově čísle. Vláknité částice se usazovali méně efektivně v porovnání s kulovými částicemi majícími stejné Stokesovo číslo. Jelikož byly okrajové podmínky dostatečně popsány a model plic je k dispozici i v digitální podobě, je možné data použít k validaci výsledků numerických simulací.
