Determination of the chemical composition of a brass sample by X-ray fluorescence method
Tomanová, Michaela ; Čudek, Pavel (referee) ; Vaněk, Jiří (advisor)
The fluorescence spectroscopy method is used to distinguish components in gas, liquid, or solid samples. The study is based on the parameters of secondary radiation, which is emitted by each element and allows them to be identified. The distinction between each radiation is analogous to a fingerprint. Apart from quantitative and qualitative analyses, the method can be used to determine the thickness of metal layers and alloys. Laboratory analysis has a broader range of application than portable devices, which are also available. In the laboratory, two methods of measurement are available: wavelength dispersive fluorescence spectroscopy – WDXRF and energo dispersive fluorescence spectroscopy – EDXRF. A brass sample with lead additive was analyzed using EDXRF in the practical part of this diploma thesis. An X-ray apparatus from the Leybold company was employed for the analysis, which will be used for education of lower grades at the university. A measurement station and a laboratory assignment were developed as part of the thesis, the aim of which will be to determine the chemical composition of a brass sample using the X-ray fluorescence method.

English Language in AJEI-H Technical Courses
Tomanová, Michaela ; Šťastná, Dagmar (referee) ; Zmrzlá, Petra (advisor)
Cílem této práce je poskytnutí přehledu technicky zaměřených předmětů vyučovaných programu Angličtina v elektrotechnice a informatice a poskytnout konkrétní diskurzní analýzu dostupných vyučovacích materiálů. Přehled obsahuje metody vzdělávacích kurzů a jejich cíle, stejně jako předpokládané výstupy. Dále se práce zabývá metodami a kritérii hodnocení, strukturou portálu informačního systému E-learning a doporučenou literaturou. Nakonec je popsán vyučovací přístup. Pro diskurzní analýzu byly vybrány výňatky z prezentací, skript nebo knížek doporučené literatury. V těchto analýzách je popsána struktura obsahu, gramatická a lexikální koheze a obsažnost terminologie. Tyto výňatky jsou také srovnány s teoretickými poznatky o profesionálním vědeckém stylu.

The role of the nutritional therapist for people living with HIV
Tomanová, Michaela ; Starnovská, Tamara (advisor) ; Procházka, Ivo (referee)
Nutrition is one of the prognostic, predictive and also modifiable risk factors for the development of civilization diseases, which unequivocally cause the highest mortality in our territory. Obesity, metabolic syndrome, cardiovascular disease, hypertension, and type 2 diabetes mellitus have been shown to progress earlier and more progressively among people living with human immunodeficiency virus (PLWH) rather than in the HIV-negative population. Thanks to the modernization of antiretroviral therapy (ART), the incidence of wasting or lipodystrophic syndrome among adherent individuals is very low, if not zero. However, HIV infection together with the ART and unhealthy lifestyle now represent a certain risk of undesirable comorbidities in the form of civilization diseases. The complex topic of nutritional care for PLWH should be part of the professional knowledge of every nutritional therapist. Questionnaire surveys intended for qualified nutritional therapists and educational institutions, which were applied for the first section of the practical part of this thesis, confirmed all formulated hypotheses. The result of this part is the finding of insufficient education and the absence of deeper knowledge in the field of nutrition for PLWH among almost 95 % of the interviewed nutrition therapists,...

Victimization in Margaret Atwood's The Blind Assassin
Tomanová, Michaela ; Topolovská, Tereza (advisor) ; Chalupský, Petr (referee)
The aim of this thesis is to explore the theme of victimization in Margaret Atwood's novel, The Blind Assassin. The theoretical part of the work presents two theories elaborating on this topic. The first Atwood outlined herself in Survival, her influential book about Canadian literature. The second one is Trauma and Recovery by Judith Herman, which highlights the role of post-traumatic stress disorder as a result of abuse, often in the victim's childhood. In the practical part, Atwood's widely acclaimed 2000 novel, The Blind Assassin, is interpreted through the prism of these two theories.

Nutritional care and eating habits of people living with HIV
Tomanová, Michaela ; Starnovská, Tamara (advisor) ; Procházka, Ivo (referee)
The relationships between nutritional status, infectious diseases, and the immune system suggest that nutrition is an indisputable cofactor in the progression of human immunodeficiency virus (HIV) infection. One of the main complications of HIV infection is multifactorial malnutrition, however, overweight and obesity have become more frequent. A specialized nutritional intervention should be an integral part of routine medical care for people living with HIV. It has been shown that the incidence of wasting syndrome and critical malnutrition among people living with HIV has significantly decreased simultaneously with the side effects of modern antiretroviral drugs. The side effects of modern antiretroviral therapy are much less common than previous generations of drugs. On the other hand, the prevalence of obesity and other chronic diseases associated with it has increased significantly among people living with HIV. The practical part describes and evaluates the monitoring of eating habits of 10 people living with HIV. The aim of this work was to provide a summary of information about proper nutritional care for this population, to evaluate the eating habits of the respondents and to come up with a potentional nutritional intervention and education. Lack of macro and micronutrients and poor eating...

Development of adolescent identity in selected novels by John Green
Tomanová, Michaela ; Topolovská, Tereza (advisor) ; Chalupský, Petr (referee)
The American YA novelist John Green frequently centres his books on characters that have been struck by the death of somebody close to them, by a traumatic event, or suffer from debilitating illness. Since adolescence is an important and impressionable period of life during which one's identity is firmly established for the first time, such experiences inevitably have a lasting impact on the person and their sense of self. This diploma thesis analyses how the teenage heroes in two selected works by Green - The Fault in Our Stars (2012) and Looking for Alaska (2005) - construe their identity when simultaneously facing death and/or trauma. The analysis takes as its foundation the theories of (inter)subjectivity and of the Other by literary critics Robyn McCallum and Karen Coats, respectively, and is complemented by the outline of psychological development from James E. Marcia. Interpersonal relationships are at the crux of a stable adult identity, and are essential for successful integration into wider society. If these are missing, the individual is marginalised as a threat to others, possibly dying as a consequence of their status. KEY WORDS John Green, young-adult literature, adolescence, maturation, identity, the Other, death, grief, terminal illness, The Fault in Our Stars, Looking for Alaska
