X {--} ray exposition parameters for imaging of prehistoric material.
HOLUB, Jan
The research of prehistoric skeletal samples using X {--} ray techniques is now a routine practice. With the development of digital technologies, the process of image is significantly faster, and subsequent processing brings more information that increases the yield of such research. Due to the availability of different systems, it is not clear which technology is the best for anthropological purposes. Moreover, when there is a huge quantity of samples to be imaged, we often obtain poor quality images. That in turn requires us to experiment with the setting of proper exposure times, thus slowing the entire imaging process. The objective of this work is to determine exposure parameters for prehistoric skeletal samples and to evaluate their effectiveness in direct and indirect digitalization systems. A subsequent goal is to compare the devices in terms of operation, quickness and quality of images, and to provide recommendations for the most suitable technology for working with these samples.

Hooligans in Czech republic
Holub, Josef ; Hudík, Marek (advisor) ; Rod, Aleš (referee)
This work ananlyzes behavior of football hooligans in Czech republic. We focus especially on the question why do the Czech hooligans involve in riots and fights more than their British counterparts. Not long ago, the British hooligans belonged to the most dangerous hooligans in Europe. We show what was behind the change of their behavior and thus caused that the stadium became a safe place to watch a football game. We try to determine whether these measures are generally applicable within the economic approach to behaviour. The practical part tries to find out how this problem is faced by the Czech Football Association and major league clubs and whether to fight this problem is for them feasible at all. In the final part. I suggest measures that could help to solve the problem with hooligans.
