Analysis of the facial form and shape in children from birth to 2 years of life
Wiesnerová, Markéta ; Velemínská, Jana (advisor) ; Moslerová, Veronika (referee)
This thesis focuses on the modeling of facial developmental changes in a group of children from 3 months to 2 years of age who do not show any demonstrable pathology. Growth and shape differences, variability and sexual dimorphism of facial form and shape were monitored in 85 girls and 81 boys using 3D facial models. 3D scanning was performed only once for each individual, this is a transversal study. A total of 166 facial models were used. Full surface models of the face will be used for analysis and will be cropped and cleaned before processing to contain the same information for all individuals. As part of the methodology, the CPD-DCA method (Coherent point drift - Dense correspondence analysis), analysis of main components will be used. The results of the analyzes were presented in the form of superprojection color - coded maps of average faces. These maps visualize the results of statistical analyzes and allow us to better understand the differences in the form and shape of the face between the observed groups. In the monitored period, sexual dimorphism was insignificant. Despite this, the average face of boys was larger compared to the average face of girls. We observed a wider and larger forehead area in male. In the area of the cheeks, nose, lips and chin, we noted protrusion, which means...

Scent glands of true bugs (Heteroptera) and their pattern in micropterous bed bug Cimex lectularius (Cimicidae)
Wiesnerová, Markéta ; Vilímová, Jitka (advisor) ; Kment, Petr (referee)
Chemical communication is considered to be very common type of communication within the insects. Taxon true bugs, the suborder Heteroptera (Insecta: Hemiptera) is well known concerning this type of communication. It is based on a secretion of glands from which the most important are dorsoabdominal scent glands (DAGs) of nymphs and metathoracic scent glands (MTGs) of adults. The present study includes a summary of the knowledge about heteropteran scent glands, including the glands in micropterous bed bug, Cimex lectularius (Linnaeus, 1758) (Cimicidae). Also information about chemical composition and function of the secretion is included. Key words: Heteroptera, DAGs, MTGs, scent glands, bed bug Cimex lectularius, composition of secretion
