Water chiller for ceiling cooling system
Havlíček, Jan ; Chovancová, Michaela (referee) ; Hejčík, Jiří (advisor)
The topic of this diploma thesis is to design water chiller for ceiling cooling system. The thesis is divided into four main parts. The first part deals with the theoretical description of emitting cooling systems. The following part focuses on the theory of refrigerating systems and describes especially the thermal cycle and refrigerants which are used in cooling systems. In the third chapter refrigerating equipment are described. Compressor, heat exchangers and expansion valves belong to the main parts of refrigerating systems. The final chapter is devoted to the draft and selection of components of the refrigerating system.

Hybrid ventilation in buildings
Havlíček, Jan ; Pešek, Martin (referee) ; Charvát, Pavel (advisor)
This bachelor thesis deals with hybrid ventilation in buildings. The first part of the thesis discusses ventilation, the classification of ventilation and then natural and mechanical ventilation are summarized. The second part focuses on hybrid ventilation. Here the classification of hybrid ventilation, 2 examples of hybrid ventilation in non-residential premises and 4 hybrid ventilation systems for 4 climate zones are mentioned.

Anthology of Unspoken: Surreal Complexity of Mind
Hrádková, Jana ; Havlíček, Jiří (referee) ; Macháček, Mikuláš (advisor)
The diploma thesis Anthology of Unspoken is a form of personal therapy, a coping mechanism in the shape of an extensive personal research presented by visually eclectic web, which maps the perception of depression and melancholy in terms of historical, artistic, and partly academic discourse. AoU takes the form of a website on the border of an archive and a research blog, which visually reminds a notebook with the use of texts in the form of notes, reader view essays, and accompanying visual material (period paintings, pop-cultural references, emoticons etc.). This diploma thesis has two main goals. Firstly, it represents a way of finding means to articulate and at least fractionally understand my own problems. Secondly, it is a way of finding answers to the following questions: Is depression really a modern matter of the 21st century? Why is it so difficult to talk about it? Where do the shame and feeling of guilt, with which it is inextricably associated with, come from? Is melancholy synonymous with depression, or do these terms differ from each other? And is depression really a disease or is it only a sign of my own failure?

The influence of prenatal hormones on the emergence and development of homosexual orientation in women with congenital adrenal hyperplasia.
Pakhomova, Alena ; Havlíček, Jan (advisor) ; Šebánková, Blanka (referee)
Female homosexuality is a complex phenomenon, and therefore, the causes of the emergence of female homosexuality are the subject of extensive debates. There are various theories about the origin of female homosexuality, and one of them is the neurohormonal theory. The neurohormonal theory assumes that the organizational effects of prenatal hormones in the early stages of development influence sexual orientation. Congenital adrenal hyperplasia (CAH) is a condition in which affected women are exposed to high levels of prenatal hormones. In women with CAH, a higher frequency of homosexual and bisexual orientation is observed compared to the general population. The effects of prenatal hormones can explain this. However, most women with CAH are still heterosexual, and there is also a significant number of lesbian and bisexual women who do not have any disorder. This also suggests that hormones are certainly not the sole factor contributing to the development of homosexual orientation. Keywords: female homosexuality, neurohormonal theory, organizational-activational hypothesis, congenital adrenal hyperplasia, disorders of sexual development.

Preferences for markers of health status in humans
Jíchová, Františka ; Havlíček, Jan (advisor) ; Fiala, Vojtěch (referee)
Several evolutionary hypotheses suggest that different organisms have evolved systematic preferences for markers of mate health. These markers may provide clues to an individual's immunocompetence, current health status, and health history. Correct recognition of good health helps to select a quality partner who can offer advantages such as good genetic qualities that can be passed on to offspring, can participate more effectively in the care of offspring, and thus does not put the individual at risk of infection. Awareness of these markers may be important not only in mate choice but also in other social interactions in which it is important mainly to correctly estimate current health and possibly avoid interaction with an infectious individual. Preference for markers of health in humans may be based, for example, on visual cues in the face, such as color, sexual dimorphism, skin texture, or an assessment of overall stature. Markers may also be olfactory, where an unattractive odor may indicate the presence of a potential disease. Last but not least, there are acoustic markers. However, the interaction of the manifestations of each modality may also be important. The aim of my bachelor thesis is to provide a theoretical overview of the association of current health, immunocompetence and health...

Personality differences in individuals of various sexual orientations
Fořt, Jakub ; Havlíček, Jan (advisor) ; Procházka, Ivo (referee)
The previous research identified a range of personality differences between men and women of various sexual orientations. Non-heterosexual individuals systematically show higher gender nonconformity and greater openness to experience than heterosexual individuals. Non-heterosexual men also show higher levels of neuroticism compared to heterosexual men. The main aim of this study is to replicate previous findings regarding personality differences. The study further aims to determine whether some of the observed differences in personality factors might be explained by differences in gender nonconformity among individuals of various sexual orientations. Via an online survey, a short version of the Big Five Inventory (BFI-10) and a number of scales measuring gender nonconformity were administered to men (N = 3,418) and women (N = 4,690). In total, 232 individuals identified as asexual, 1,814 as bisexual, 3,024 as heterosexual, 2,468 as homosexual, and 570 as pansexual. Our results demonstrate higher gender nonconformity among non-heterosexual men and women, higher neuroticism among non-heterosexual men, and greater openness to experience among bisexual men and women compared to heterosexual individuals. Asexual women showed lower levels of extraversion than women of other sexual orientations. Gender...

Nausea and vomiting in pregnancy: An evolutionary perspective
Roberts, Kateřina ; Havlíček, Jan (advisor) ; Żelaźniewicz, Agnieszka (referee) ; Šebela, Antonín (referee)
The symptoms of nausea and vomiting are experienced by a majority of women during their pregnancy. Symptoms range from mild to severe, but even mild symptoms are connected with adverse effects on women's everyday life. Despite its significance, the aetiology of nausea and vomiting in pregnancy (NVP) is not fully understood. The first part of this thesis briefly summarises what is known about the predictors and mechanisms of NVP, including hormonal influences, pregnancy-related, demographic, lifestyle and psychosocial factors. Furthermore, this part focuses on NVP from an evolutionary perspective that, compared to the generally negative view, recognises that NVP has some positive effects on pregnancy outcomes. Different adaptive hypotheses of NVP are described, such as the maternal and embryo protection hypothesis and the compensatory growth hypothesis. The second part consists of five studies focusing on NVP and related topics. The first study focused on dietary and psychosocial correlates of NVP and found a relationship between the level of NVP symptoms and the consumption of milk products and alcohol and a relationship between NVP and stress, anxiety, fatigue and perceived partner support. The next three studies focused on various predictors of NVP and its relationship with disgust in pregnancy....
