Evaluation of the efficiency of root treatment plants via ecotoxicity tests
Konečná, Kateřina ; Procházková, Petra (referee) ; Zlámalová Gargošová, Helena (advisor)
This bachelor thesis focuses on the evaluation of the efficiency of root treatment plants using appropriately selected ecotoxicity tests. For these purposes, ecotoxicological tests in an aquatic arrangement were used, specifically with the planktonic organism Thamnocephalus platyurus and the plant Lemna minor. The evaluation was performed at a municipal root treatment plant, which treats water for 955 equivalent inhabitants. The results of tests with T. platyurus confirmed that the root treatment plant sufficiently relieves acute toxicity of water. LC50 values were determined for two samples, 213.71 ml / l for the inflow and 388.20 ml / l for the settling tank. At the outflow, these values could no longer be determined due to the low ecotoxicological effect of the water thus treated. For tests with L. minor, IC50 values were also calculated for the first two samples. For Sample No. 1, the IC50 value was calculated to be 311.25 ml / l, for Sample No. 2 to 963.35 ml / l. However, on the basis of tests of direct toxicity of waters with L. minor, it is possible to confirm even in the case of this organism, a good cleansing effect of this root treatment plant.

The Use of Hluchov Floodplain Forest and Houšťka Park Forest in Tuition of Natural History and Biology
Procházková, Petra ; Skýbová, Jana (advisor) ; Hanel, Lubomír (referee)
The diploma thesis deals with the use of the localities Houšťka Forest Park and Hluchov Floodplain Forest in the teaching of natural history at the 2nd level of primary schools, biology at the lower levels of grammar schools and at vocational secondary schools. Part of the theoretical part is a description of natural conditions and history of the site, the division into habitats and their characteristics. Furthermore, an inventory and description of plant species, including a list of zoological taxa, was performed for the needs of teachers. The questionnaire survey among teachers was focused on the use of localities during regular lessons, or compulsory optional subjects focused on natural history. The time required for the worksheets was based on the results of this survey. The didactic part includes the issue of interdisciplinary relationships, enumeration and description of forms and methods used in the teaching of science and biology. The main part of this part of the thesis are worksheets, which are in addition to consolidating knowledge of natural sciences and biology focused on the application of knowledge from other subjects such as mathematics, physics. After completing the worksheet, the individual exercises were corrected. In the qualitative research, on the basis of a questionnaire...

Pastoral care of people with intellectual disability. Example of anthroposophy approach
Procházková, Petra ; Martinek, Michael (advisor) ; Křížová, Eva (referee)
Pastoral care of people with intellectual disability is a quite new discipline in czech discourse. The aim of this bachelor work is to introduce, how pastoral care of people with intellectual disability looks like and how it function. Resource of the pastoral care is in gospel. It pursues growth of human being in level of bio-psycho-socio-spiritual, and so on. The "Theology of disability" is resource for pastoral care too. "Theology of disability" tries about inclusion of people with intellectual disability and disability in general. Tries about incluison into society and community. That all through Christian's values and love. Techniques of pastoral care are in general to sing a songs, some predicitons, to read biblical texts, prayers and support in growth of human being and to deal with difficult life circumstances. Pastoral care of people with intellectual disability provides the same fundamental human rights, which have people without disabilities too. With emphesizing Christianity and anthroposophy. It provides for them to meet with themselves, and to gain their dreams, wishes, needs and face to their anxiety and fears too. That all through different techniques.

Influence of advanced oxidative processess on ecotoxicity of pesticides
Goma, Bernadette ; Procházková, Petra (referee) ; Zlámalová Gargošová, Helena (advisor)
The topic of this bachelor thesis is a study of the influence of advanced oxidation processes on the ecotoxicity of pesticides Metazachlor and Chloridazon. Both herbicides are commonly used to protect crops such as oilseed rape, turnips, chard or fodder beet against whole range of undesirable monocotyledonous and dicotyledonous plants. Application is most often on large areas and therefore pose a high risk to the quality of the environment. The possible influence on the representatives of producers and consumers of the aquatic ecosystem was monitored in the work. Solutions of pesticides, which were subjected to selected methods of treatment using advanced oxidation processes, were tested on aquatic organisms, specifically on crustaceans Daphnia magna and aquatic plant Lemna minor. From the results of individual tests, the ecotoxicological values of EC50 and IC50 were calculated and their ecotoxicity and thus the efficiency of oxidation processes in the removal of pollutants from wastewater were compared.

Assessment of the effectiveness of advanced oxidation processes via ecotoxicity tests
Procházková, Petra ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
Recently, an increasing problem in wastewater treatment is the insufficient removal of organic pollutants. These substances can be toxic to the environment already in a small amount, either acutely or chronically. The goal is therefore to develop of technologies that ensure their effective removal. One possibility is to use advanced oxidation processes. Advanced oxidation processes work on the principle of non-selective oxidation mediated by OH radicals. Several methods such as O3/H2O2 (Peroxone), UV/H2O2 or Fenton´s reaction can be used to generate them. The aim of this thesis was to evaluate the effectiveness of the used advanced oxidation processes in wastewater treatment via ekotoxicity tests. Wastewater samples treated with advanced oxidation processes on the pilot unit showed low values of acute toxicity for selected test organisms (D. magna, T. platyurus, S. alba, L. minor). For the sample of waste water that was treated with the UV/H2O2 on AOP laboratory unit, there was an increase in acute toxicity on the testing organism D. magna and L. minor. The similar effect was observer in the tests with the D. magna with the model samples treated with the same method, while the tests on the L. minor showed a reduction in toxicity.
