Stability of soil organic matter and humic substances
Nováková, Šárka ; Enev, Vojtěch (referee) ; Klučáková, Martina (advisor)
This diploma thesis is focused on changes of stability in organic matter by extraction in different agents. Two soils of a different type and isolated humic acids were used for stability determination. Extraction agents were selected usually used for soil metal extraction, and a changes in the structure of the organic matter was observed. Samples were characterized using FTIR analysis and elemental analysis, the extracts were measured by UV-VIS spectroscopy, absorption ratios E2/E3, E4/E6 were discovered, dynamic light scattering were determined for particle size distributions. Next part of the thesis was the assessment of the change of thermal stability using thermogravimetric analysis and differential scanning calorimetry, degradation temperatures of the extracted samples were discovered and compared with the original samples.

Stability of humic substances
Nováková, Šárka ; Smilková, Marcela (referee) ; Klučáková, Martina (advisor)
This bachelor´s thesis is focused on the study of stability of humic acid. Thesis is divided in two parts, the first part is theoretical. In the theoretical part is dealing with the structure, property and point of humic acid and in the experimental part is dealing with stability of humic acid. The objective of this thesis was to investigate the effect of the extraction agents on stability of humic acid. 1M HCl, 1M MgCl2 and MiliQ water was used like extraction agents. Thermo-oxidative stability was tested trough thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Changes of humic acid that occured after extraction were investigated by FT-IR spektrometry and elementary analysis. The results of the measuring were compared with original humic acid.

Physiotherapy of patients after a stroke in the home environment
NOVÁKOVÁ, Šárka
The bachelor thesis is divided into a theoretical part and a review study. The theoretical part is described in three chapters. The first chapter of the theoretical part deals with stroke. It also describes epidemiology, pathogenesis, risk factors, clinical picture, diagnostics and treatment of stroke. It also dedicated to the consequences and prevention of stroke. The second chapter is devoted to coordinated rehabilitation, which is crucial in the care of stroke patients. This chapter further describes the multidisciplinary team and its work, institutions providing physiotherapy, patient care and medical rehabilitation of stroke patients, and physiotherapy methods used in the treatment of stroke survivors. The third chapter of the theoretical part describes the return of patients to their home environment and includes a sub-chapter where set of recommendations for patients and their families is made. For the review study, 20 researches were selected and result tables were created from them. In these tables it is possible to find a description of the physiotherapy techniques used in studies, the members of the multidisciplinary team in the home environment, the characteristics of the research group, the frequency of physiotherapy and a note containing the topic of the article.

The Borges - Eco Labyrinth
Nováková, Šárka ; Hubík, Jaroslav (advisor) ; Češka, Jakub (referee)
The task of the thesis is to define notion of the labyrinth according to Umberto Eco (mostly in his Notes on the Name of the rose) and J. L. Borges in his short stories. The idea of the labyrinth as the metaphore for the textual universum will be brought up within the wider context in the following chapters. Concept of "the labyrinth" and "the Library" is mainly connected with deconstructive philosophical line and the second part is about their philosophical basis clarification. This section explains the possibilities of reader's moves in the maze: his strategy (Lyotard), way of the movement (Derrida) and potential restrictions (Eco). Another important part of the thesis is the topic reflexion in media - specifically in the film. Interpretation of the selected motion pictures will be aimed at those elements, which are important for the subject of the writing (labyrinth, book, intertextuality…).

Biologicky rozložitelné materiály a jejich vliv na odpadové hospodářství
Nováková, Šárka
The main objective of the thesis was to verify whether biodegradable disposable diapers decompose, depending on the statement of the manufacturer. In this work, there were used three different samples available on the Czech market. These samples were composted both under laboratory conditions and in terms of domestic composting. At the end of the experiment, samples were weighted and their weight loss was calculated in percentage. Two of the three samples have met stated values of the manufacturer. The last sample did not comply with reported values of the manufacturer.
