Religious hemophilia in an environment of social networks
Andršová, Markéta ; Šlerka, Josef (advisor) ; Sedláček, Jakub (referee)
This bachelor thesis focuses on religious homophilia on social network sites. The platform on which the issue is presented is Twitter, which is very suitable due to its extensive using of hashtags used to search for other users' social interests or opinions. The main question of this thesis is to find out whether the principle of homophilia on Twitter among the religious community is present. To confirm the purpose, manual data mining is used. The practical part continues with qualitative research, in which the obtained results are comparted to the answers of the respondents.

Religious hemophilia in an environment of social networks
Andršová, Markéta ; Šlerka, Josef (advisor) ; Fiala, Jakub (referee)
The theme of this bachalor theses are religious homophilic relationships on czech Twitter. The theoretical part is focused on homophilic principle and its sociological areas into which is projected; such as race homophily, gender homophily, political homophily, religious homophily or homophily in romantic relationships. The theoretical part is also desribing the problematice of social network services and its homophily. The main part if the thesis is consists of research on Twitter. The research was conducted to find out how much is a religious content represented on Twitter and how much is its representation different from an atheistic represenation.

Characterization and functional analysis of IST2 gene in yeast Saccharomyces cerevisiae.
Andršová, Markéta ; Sychrová, Hana (advisor) ; Hlaváček, Otakar (referee)
IST2 is known as a gene encoding in the model yeast Saccharomyces cerevisiae a membrane protein, that is studied thanks to a unique way of biogenesis and trafficking that apparently does not use classical secretory pathway. Although the gene was named more than ten years ago according to the phenotype of cells with its deletion (Increased Sodium Tolerance), the role of this protein in cell tolerance to toxic sodium has not been elucidated. Our searches in databases revealed that similar proteins are encoded in the genomes of other species of yeast, but none of them has been studied so far. In this work, four new strains lacking IST2 have been constructed in the genetic backgrounds differing by the presence of genes encoding transport systems for accumulation of potassium (Trk1, Trk2), for export of surplus potassium cations (Tok1, Ena1-5, Nha1) and for export of toxic cations lithium and sodium (Ena1-5, Nha1). Plasmid carrying the gene coding IST2 sequence has also been conctructed. The effect of IST2 deletion in different genetic backgrounds was studied by phenotypic tests on solid and liquid media. It was found that IST2 probably does not play a role in osmotolerance in general (absence of the phenotype of IST2 deletion on high concentrations of KCl), but its presence affects ability of the cells...
