Mikrokogeneration for small rezidential buildings
 Opluštil, Marek ; Nerud, Pavel (referee) ; Pospíšil, Jiří (advisor)
The topic of this diploma study is to compile an overview of Domestic CHP units. The work is divided into three sections. The first section includes a summary of suitable CHP units. The second portion discusses the possibly methods of accumulation heat and electrical energy exploitable connection with CHP units. Last part of thesis is devoted to study apply CHP units in power supplyes choice object.

LIBS analysis of heavy metals in plant matrice
 Opluštil, Marek ; Pořízka, Pavel (referee) ; Krčma, František (advisor)
This bachelor thesis deals with the analysis of cadmium distribution in the plant matrix using laser - induced breakdown spectroscopy (LIBS). Technical hemp plants grown in soil with different cadmium concentrations were used as samples. The theoretical part focuses on LIBS methods in terms of basic principles, description of accompanying phenomena during measurements and instrumentation. Advantages and disadvantages over other analytical techniques as well as practical applications are also described. In addition, the issue of cadmium in the environment, its occurrence and use in human activities is described. In the experimental part, the methodology for sample preparation for LIBS and ICP-OES analysis is described. The aim of this work is to observe the effect of cadmium on the growth of plants that were successively harvested weekly until the fourth week. Subsequently, plant and soil samples were prepared for LIBS and ICP-OES measurements and the results were evaluated. ICP-OES analysis led to the determination of each element content. The LIBS method provided information on the areal distribution of the elements (spectral maps), allowing to see in which plants part the determined element is located. It is clear from the results of the experimental part that the LIBS method is very advantageous and efficient in the analysis of elements in biological matrices, both biogenic and toxic.
