Educational applications of the complicated biochemical processes models
Zdražil, Jindřich
My PhD study 'Educational application of models of complex biochemical processes' discusses the possibility of integrating simple bioorganic teaching experiments, modelling complex biochemical processes in living systems into a curriculum of secondary schools, and universities, and even elementary schools in some cases. The aim of these experiments is simplified, but illustrative and appropriate for approaching complex problems of biochemical processes in a transparent experiment, running in spite of conditions comparable to real natural clauses in a living system. The theoretical part is divided into three thematic circuits: biochemistry and bioorganic chemistry, bioorganic models and their characteristics and selected specific forms of applying bioorganic models into teaching chemistry. The next part dealing with bioorganic models and their characteristics is further divided on the base of some specific models. These are consisted of models of enzymes and their catalytic activity, models of biochemical reactions and antidotal and toxic substances affecting life-forms and their carcinogenic efficiency. The practical part contains methodic treatment of six selected models that demonstrate specific biochemical processes or structure of complex organic compounds. These models include modeling biuret...

Precipitation processes in light hardenable alloys and the possibilities for integrating thermal analysis into physics education on high school
Kodetová, Veronika ; Vlach, Martin (advisor) ; Černošková, Eva (referee) ; Svoboda, Pavel (referee)
The doctoral thesis is divided into two parts - Thermal analysis in physics education on high school and Material research of Al-Zn-Mg(-Cu-Sc-Zr) alloys. Within the first part, the areas of crystallization and/or melting of selected foods were determined using differential scanning calorimetry. A practical lesson for high school physics has been created and tested. The study text focused mainly on differential scanning calorimetry and its use was made. In the second part of the doctoral thesis, there was analysed thermal evolution of the phase transformation in the Al- Zn-Mg(-Cu) alloys with Sc and Zr addition. The effect of (cold and hot) deformation on the decomposition sequences was studied. The hardening effect after annealing above 300 řC in the Sc and Zr alloys is caused by the precipitation of the secondary Al3Sc,Zr) particles. These particles were observed by transmission electron microscopy after annealing up to 360 řC in all studied AlZnMg(Cu)ScZr alloys. In the AlZnMgCu alloy the partial recrystallization was observed after annealing at 350 řC/10 hours and after annealing at 450 řC/10 hours the grain size was 50-200 m (depending on the treatment of the alloy). The addition of Sc, Zr in the AlZnMgCuScZr stabilizes grains and there is no recrystallization in the AlZnMgCuScZr alloy at temperature...
