Determination of selected metals in unconventional fruit species
Křížová, Soňa ; Dočekalová, Hana (referee) ; Diviš, Pavel (advisor)
The aim of this diploma thesis is determination of selected metals in unconventional fruit species, specifically in cornelian cherry (Cornus mas), sea buckthorn (Hippophae rhamnoides) and medlar (Mespilus germanica).There is informationabout 16 analysed metals – As, B, Be, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Se, Sn, Pb, V, Zn. There are described analytical techniques for elemental analysis and methods for destruction biological material. Samples for analysis are prepared by using microwave mineralization and ICP-MS for detection. This is described in the experimental part of the diploma thesis. Analysis confirmed that unconventional fruits are rich sources of trace elements.

Trauma and connections with the use of selected addictive substances in adolescents girls in institutional care
Karlová, Markéta ; Doležalová, Pavla (advisor) ; Křížová, Soňa (referee)
Background: For girls placed in facilities, the causes of risky behavior and the extent of substance use are not sufficiently mapped. The phenomenon of trauma was chosen for this work as a possible cause of NL use. The data was not systematically processed or analyzed, it could continue to serve as a guide for improving efficiency in these devices. Objective: To identify the most common area of trauma in girls placed in institutional care, to map the prevalence of use of selected substances in the last 30 days and then compare it with the prevalence of use of girls from the general school population (ESPAD 2015). Furthermore, to find out whether more experienced traumatic events lead to a higher prevalence of substance use. Methods: The data were obtained in the form of quantitative research and implemented using the Early traumatic events record questionnaire and the modified ESPAD 2015 questionnaire. The data was transcribed by IBM SPSS Statistics and analyzed in MS Excel using descriptive statistics tools. There were 121 participating respondents. Results: Physical punishment is the most common type of trauma. Institutional girls use four times more cannabis and three times more tobacco than girls in the general school population. Girls from the general school population consume more alcohol. In...
