Neutralization of acid solutions
Pavlík, Ondřej ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
The present thesis is concerned with neutralization of acid groundwater after the hydrochemical uranium mining in the area of Stráž pod Ralskem. In the thesis is briefly described progression of the hydrochemical uranium mining and follow-up negative impacts on the environment. There is described the technology involved in its disposal. This is followed by the design calculation of major apparatus technology associated with neutralization of acid solutions. Output of technology is determined by the mass balance. The results are the main dimensions of the apparatus, mechanical parts and electric power each device.

Control methods for wastewater pH
Picka, Marek ; Vondra, Marek (referee) ; Miklas, Václav (advisor)
The bachelor thesis initially deals with the process of wastewater treatment with a focus on measurement, pH control and related issues. The pH value is an important parameter in wastewater treatment, which influences physical, chemical and biological processes as well as digestate treatment processes. This paper focuses on the process of thickening of digestate from a biogas plant by evaporation, which is normally associated with the leakage of volatile ammonia into the distillate. In order to eliminate this phenomenon, four methods of pH reduction were compared, which leads to the conversion of nitrogen from the volatile undesirable form 3 to the desirable form + 4 or 3 , which does not evaporate into the distillate during the evaporation process but remains in the concentrate, thus yielding a high quality fertilizer. Of the 4 methods discussed, the nitrification method appears to be the best in terms of the quality of the fertilizer output, but its disadvantage is the long retention time. From the point of view of flue gas utilization, lowering the pH by bubbling 2 and acidification with acid is a suitable method. For cases where speed and low acquisition costs are important, pH reduction with acid is preferable, unless high operating costs are a problem. In order to assess the correct method of pH reduction for a particular biogas plant, a techno-economic evaluation and consideration of other operational constraints is required and will be the subject of future work.

Heating of flat house
Bartoň, Dominik ; Počinková, Marcela (referee) ; Topič, Jan (advisor)
The aim of this bachelor thesis is to design the heating system and water heating for an apartment building in Ostrava. In the theoretical part, I deal with condensation technique and condensation itself. I have compared the different types of conden-sation, installation and optimal combination of condensing boiler and warming water. In the end of that part, I have explained the condensate drainage and the method of flue gas venting. In the computational part, I have compiled a complete calculation and design of individual elements that are important for the proper functioning of the entire system. At the conclusion of the thesis is a project, which is elaborated at the level of the construction documentation. The project includes the technical report and complete drawing documentation including attachments.

Electropalatographic study of voicing assimilation in Czech alveolar plosives
Vaněčková, Kateřina ; Skarnitzl, Radek (advisor) ; Machač, Pavel (referee)
The phonological contrast of voicing is based on several phonetic differences which are yet to be satisfactorily explained. The most obvious of them is the presence of vocal cords vibration which has so far been considered crucial in Czech. For capturing the differences in other dimensions, the concept of the strength of articulation, or fortis/lenis contrast have been established. There are some rare cases in languages when the couple of phonemes with the voicing contrast differs also in another feature that cannot be explained by the fortis/lenis dimension correlates. This is the case of Czech alveolar plosives which have been described to differ in their place of articulation: the linguopalatal contact is more anterior for [t] that for [d]. The main aim of this study is to ascertain whether this contrast can indicate the original phoneme in the contexts where the voicing contrast is neutralized due to assimilation. Nevertheless, our electropalatographic data from 7 speakers of Czech show that not only the phonemes do not seem to influence the anteriority of the voicing realisation, but also the very asymmetry of linguopalatal contact in the voicing realisations tends to be neutralised in the segmental context used in our study, that is in coda position in the word-final syllable followed by the...

Annotated translation: Do Women Pay for German Reunification?
Bernasová, Mariana ; Žárská, Monika (advisor) ; Veselá, Gabriela (referee)
The thesis focuses on translation of an extract of a dialogue from the book called Bezahlen die Frauen die Wiedervereinigung? and on commentary on this translation. Apart from the Introduction and Conclusion there are two parts that play central role: the Translation itself and the above mentioned Commentary. The Commentary consists of four chapters. Translation Analysis of the Original Text Based on Ch. Nord's Model describes extratextual and intratextual factors of the original text. Features of the Original Text and First Insights into Problems of Translation takes functional-structuralist approach, describing different levels of the language used, focuses on tricky parts in the translation and thus links the analysis of the original with the translation. Method of Translation sets strategy for the translation of the original, based on conclusions of the two previous chapters. Typology of Translation Solutions and Unavoidable Shifts - Concrete Examples puts the method into practice, gives examples and comments on problems.
