In this work I study the advanced geophysical method - the time domain electromagnetics. In the theoretical part I summarize principles of the method, describe several measuring systems and guide the reader through the software for data processing. I further prove reliability of the applied methodology by forward and inverse computations for a simplified model of supposed target structures. The results show that for the selected configuration of field measurements with a depth range of 100-200 m the influence of 3D structures is significant when placed in a distance smaller than approximately 100 m. In the practical part I test the method in the sedimentary environment and find that results of the method are in accordance with the vertical electrical sounding method. Subsequently, I show that the artificial highly conductive object placed inside the current loop significantly affects the outcomes of the method. Artificial conductive object has only minute effect if placed in a close distance but outside of the current circuit. Besides the theoretical and experimental findings about the reliability of the method I have applied the method for research of maar volcanoes. I have confirmed with high probability the presence of maar volcano near the Jablonná village. The results measured close to the...

The diploma thesis deals with the book genre Erstlesebuch (book for beginner readers) as educational material in the context of foreign language education at the levels of Basic Users (A0/1-A2). In the context of first language teaching, this specific genre belongs to the field of literature, the didactic of literature, and the didactic of reading. The goal of this diploma thesis is to present different possibilities of didactic activities with Erstlesebuch in the context of second language teaching and to formulate criteria for choosing an appropriate text. The theoretical part describes the context of foreign language education and the role of literature in this context, with consideration for the Common European Framework of Reference for Languages. The theoretical part also presents the specifics of the book genre Erstlesebuch itself. The empirical part of this thesis is based on several investigations: firstly on a complex analysis (readability and text structure) of six Erstlesebuch and secondly on empirical research in reading with schoolchildren at higher grades of an elementary school (children at the age of 13-15). These results are compared to the results of similar research done with Austrian beginner readers (children between the ages of 7 and 9). The final part of the thesis concludes...
