Návrh lisovacích přípravků na manifoldové sestavy kondenzátoru automobilové klimatizace / Design of pressing machines for manifold assembly of condensers in car air-conditioning unit

Juriga, Jakub January 2016 (has links)
The diploma thesis deals with the design of pressing machines for manifold assembly of condensers in the car air-conditioning unit. The problem of the current assembling process is its inefficiency. Semi-automated assembly using pneumatic pressing machines eliminates this problem. In the theoretical part the air-conditioning components, current state of assembly and calculating base of pressing are described. In the practical part the test of pressing force was conducted. Based on this test, the design of four pneumatic pressing machines was accomplished. In the final part of the work, evaluation of the whole project is provided.

Suicidální myšlenky adolescentů: analýza zpráv z hovorů krizové linky se zaměřením na rizikové faktory / Suicidal thoughts of adolescents: an analysis of reports from crisis helpline calls focusing on risk factors

Vondráčková, Veronika January 2019 (has links)
This paper aims to provide insight into the risk factors contributing to suicidal ideation and behavior among adolescents. First, the author overviews the extant academic literature on the subject. She highlights the persistently high incidence of suicide among young people in the Czech Republic and briefly defines the stages of adolescence as well as the particular forms and methods of suicidal behavior. Subsequently, the author discusses in detail individual aspects of demographics, clinical data, familial environments and interpersonal relationships that the academic literature associates with an increased risk of suicidality among adolescents. Concluding the overview, the author sets the topic of suicide into the context of a children's crisis helpline. The author goes on to present an empirical analysis of reports documenting suicidal calls made to a children's crisis helpline. She uses both qualitative and quantitative methods to identify particular life circumstances that may contribute to the development of suicidal ideation and/or behavior, paying attention to distinct aspects of suicidality and to gender differences. As part of her analysis, the author critically evaluates the benefits and pitfalls associated with the use of data obtained from an anonymous crisis helpline.
