Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

The use of biomass ash
Ochecová, Pavla ; Tlustoš, Pavel (advisor) ; Radim, Radim (referee)
One of the most frequently used sources of renewable energy is biomass, mainly wood biomass. Incineration is the most common technology utilizing the energy from biomass to produce heat. A byproduct of these technologies is ash, whose composition depends on the feedstock composition and the incineration technologies. Due to the high content of valuable nutrients in ash, one of the suitable option for ash utilization seems to be application into agricultural or forestry land. Therefore, it is necessary to test response of soils and plants and look for the most suitable combination of soil additive (biomass ash), and plants. Experimental part of PhD thesis was divided into the incubation experiment and the vegetation pot experiments. The incubation experiment: The efficiency of ash addition at two application rates was tested for nutrients enrichment in different soils within period of 56 days. The vegetation pot experiments: The two plants Triticum aestivum L: (three-year experiment) and Lolium perenne L. (one-year experiment) were planted in the 5L pots. Soils were treated with ash or ash combinated by superphoshate and flue gas desulfurization gypsum. For both plants, we evaluated the plant growth, biomass production and content of macro, micro and toxic elements in the biomass and in the soils.

Design and implementation of e-learning in the area of interest
Marešová, Nikola ; Husa, Jiří (advisor) ; Marek, Marek (referee)
The bachelor's thesis entitled "Design and implementation of e-learning in the area of interest" deals with buying used cars. The essential part of this work is a creation of e-learning course for buyers and other people interested in this area which aims to improve their knowledge. The participants will get an overview of the most common situations and problems they can meet when buying a used car. The theoretical part presents an overview of the topics of the issue of purchase of used cars. It may serve as a theoretical guidance to the e-course, it brings its content. The topics are based on the analysis of information from printed and electronic sources, supplemented by experiences of the author and experts in the field. The practical part deals with the creation of an e-learning course. It contains an analysis of the needs of buyers, the reasons for the creation of the course and the requirements of it, its objectives, a description of the used authoring tool eXe and graphic creation process from the creation of the course after its publication in steps. All this is complemented by the feedback from six volunteers who have expressed an interest in testing the course and then doing a review. Before the creation of the course it was necessary to analyze the situation and find out why such a course is needed. The acquired knowledge was then processed in the course by the synthesis method. For the evaluation method it was used a short personal interview where the author examined satisfaction with the course, its possible shortcomings and suggestions for improvements or enhancements.

František Jílek, distinguished conductor of Janáček Opera Brno
Kružík, Robert ; PETRÁŠ, Miroslav (advisor) ; BERNÁŠEK, Václav (referee)
Almost twenty three years after the death of František Jílek, his name is still well known in the narrow professional circles. I myself associate it since my early childhood with the Janáček music and the interpretative precision of his own, which all the musicians remember, who have worked with him for years. In this work I will focus particularly on Jílek´s period in the position of the Chief of the Brno Opera. I will demonstrate his diligence by many reviews of his premiere Opera titles, which have been a lot in almost 30 years of his acting at this position. Furthermore, I would like to mention his teaching at the music faculty of JAMU and the five year term at the position of the Chief conductor of the State Philharmonic Brno.

The collection of published articles
DVOŘÁK, Petr
The aim of the collection of published articles is to define the requisite social skills of the English language teacher as a part of his/her professional competence, in the context of communicative language teaching in classroom interactions between English teachers and adolescent pupils. The theoretical preliminaries of the research whose findings are presented in the articles are the functional communicative approach to language and communicative language teaching. The attention is paid to the processes of interaction, communication and classroom discourse at school with an emphasis on foreign language teaching. We try to specify social skills of the English teacher and define social-skill aspects of foreign language educational interactions. The findings of the research presented in the articles concern mainly the educational style of English teachers and English teacher's behaviour in particular classroom interactions. The research is also focused on selected social-skill aspects of classroom discourse within communicative language teaching, specifically, pupils' and teachers' initiations of communication, questions, and the distribution of communication opportunities.
