Identification and investigation of key biotic and abiotic factors in sewage sludge bio-drying process
Pilnáček, Vojtěch ; Innemanová, Petra (advisor) ; Najmanová, Petra (referee) ; Wrzecionko, Jakub (referee)
The work is focused on the pretreatment of sewage sludge after anaerobic stabilization by the process of biodrying. Biodrying is a process in which the organic substrate undergoes aerobic decomposition and at the same time, due to the increased temperature and the blowing air, it is dried. The aim of the work was to optimize the most important process variables, to verify whether the process is suitable for pretreatment of sewage sludge before use as fuel or fertilizer in the context of Czech legislation and to investigate which groups of organisms and how they participate in the degradation of endocrine disruptors. For these purposes, quarter- and semi- operational bio-drying reactors were designed. The results of the work show that the most important process parameters are the aeration rate and temperature as its dependent variable and the substrate composition. The setup with a fixed time interval of blower switching was found to be the optimal aeration regime. The optimal substrate composition was a 5:2 ratio of sludge:birch chips. The results of the work further show that the bio-drying process is suitable for the preparation of fuel for co-incineration with other material. It is not very suitable for mono-incineration due to exceeding emission limits. The calorific value of the resulting fuel...

The language of Italian young people and its specifications
Najmanová, Petra ; Špaček, Jiří (advisor) ; Štichauer, Pavel (referee)
The main aim of the thesis is to analyze the language of Italian youth with its all aspects, characteristics and relation to the cornrnon language. I try to realize the inf1uence of particular social factors and difference of the cornrnon language of youth from language of preceding generations. At present is the young generation cornrnunication linked as never before with various advanced technologies such are pes or cell phones. These are main factors inf1uencing the language of youth. Another issue create mass media e.g. television and radio broadcasting, press, which are interfering the age-group with a view to address and profit. Great portion in forrnation ofthe language of youth is predisposed by altemative music styles, sports, literature (comics), certain role plays slang e.g. ofthe drog cornrnunity.
