Modification of bleaching technology in production of annual plants pulp
Kouřil, Čeněk ; Touš, Michal (oponent) ; Kunert, Vojtěch (vedoucí práce)
The diploma thesis deals with the bleaching process in paper production. The main goal of this work is to evaluate the current state of bleaching technology in the company OP Papírna, s.r.o. and to propose a modification that will lead to the higher efficiency of this technology. To solve the assignment, a search of technological principles of bleaching and laboratory experiments were performed to find the appropriate solution. The contribution of the experiments was supported by technological calculations. The results of experiments have shown that the current state of bleaching technology can be made more efficient in several ways. It was proven that the submitted proposals have the potential for large economic and chemical savings. The reader of this thesis will get a basic overview of pulp and paper production technology with a focus on the bleaching process and gain knowledge of its balance calculations.

Hydrodynamické vlastnosti systémů hyaluronanu a lysinu
Kunert, Vojtěch ; Kratochvílová, Romana (oponent) ; Chytil, Martin (vedoucí práce)
Tato bakalářská práce prozkoumává interakce mezi hyaluronanem a částečně protonizovanými aminokyselinami lysinem a argininem. K popsání interakcí bylo využito reologie a viskozimetrie. K jejich kontrole pak pH-metrie a konduktometrie. Jednotlivé vzorky byly proměřeny a srovnávány nejen mezi sebou, ale také z pohledu částečné a úplné protonizace. Interakce byly pozorovány v celém rozsahu zvolených koncentrací.
