Analysis of digital hierarchy traffic
Herman, Vít ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
In diploma thesis is theoretically described structure of PDH, SDH and multiplexing of PDH to SDH. Measurement of first level PDH and SDH is described too. A design of new laboratory network was based on theoretical information and the network was build. SDH nodes MSH11CP and other equipment in laboratory entourage are used in new laboratory network in a way that laboratory network is the most similar to real telecommunication network. Operation manual for SDH nodes type MSH11CP is described next in the thesis. New three laboratory tasks are described in the thesis. These tasks make use of design of new network and a reference of nodes operation manual. New three tasks are implemented in new laboratory network, in laboratory of transmission technologies. In these new laboratory tasks are possible to create a transmission path and measure this service, including settings and verification of a backup path.

A possible role of proline in plant stress memory
Ušák, David ; Holá, Dana (advisor) ; Konrádová, Hana (referee)
The previous exposure to abiotic stress such as drought may prime plants, leading to their improved response upon later stress onset. This phenomenon, called plant stress memory, is linked to a plethora of mechanisms exerted on several levels. A complex analysis of proline metabolism in leaves and roots was performed to test the putative role of proline in such response to recurrent stress, represented by two periods of water deficit, interrupted by a period of rewatering during recovery. To provide a better understanding of intraspecific differences in drought stress memory response of plants and its inheritance, maize (Zea mays L.) parental genotypes with differing drought sensitivity and their F1 reciprocal hybrid offspring were chosen as the plant material. The water deficit had a more pronounced effect on proline metabolism in leaves than in roots. The proline content increased in response to drought, which was linked to a higher proline biosynthesis and a lower proline catabolism. Marked differences in proline metabolism among genotypes were observed, confirming the previous findings that recurrent drought response is not conserved even within the same species. However, contrary to the original assumptions on the role of proline in plant stress memory, the statistical analysis showed that...
