The use of alternative coagulants in water treatment
Hofmanová, Lucie ; Zelený, Zdeněk (referee) ; Kučera, Tomáš (advisor)
This bachelor's thesis deals with the use of alternative coagulants in water treatment. The first theoretical part mentions types of water treatment for the individual categories of raw water, related laws and ordinances. After that thesis describes the principle, mechanisms of coagulation and factors influencing the process. It analyses the jar test procedure performed within the experimental part of the bachelor's thesis. One chapter deals with polymers and metal coagulants based on aluminium and iron commonly used in water treatment. The chapter includes more detailed description of natural polymers moringa oleifera and chitosan. These two coagulating agents and aluminium sulfate were used in the second experimental part of the bachelor's thesis. Several sets of the jar test were performed in order to investigate the efficiency of chosen coagulants on the removal of turbidity from water. The thesis concludes with a comparison and evaluation of the results. Photos taken during the jar test can also be found at the end of the bachelor's thesis.

Model research on the effectiveness of separation technologies for water treatment
Hofmanová, Lucie ; Látal,, Milan (referee) ; Kučera, Tomáš (advisor)
This diploma thesis deals with the effectiveness of separation technologies for water treatment. The first theoretical part mentions types of pollution that can be found in surface water. Furthermore, the interparticle interactions affecting the stability of colloidal dispersions are discussed. The following is a description of the principle, procedure, mechanisms of coagulation and factors influencing this process. The chapter dealing with types of water treatment is followed by a more detailed description of the individual separation technologies used in the water treatment plants. The important passage in the theoretical part is the description of materials and reagents used in laboratory experiments. The coagulants nanoiron and sodium water glass are characterized, as well as Bayoxide E33, CFH 0818, FILTRASORB 100 activated charcoal and DORSILIT silicate sand. The experimental part of the thesis analyses the jar test procedure. The flocculation tester intended for the jar test was used for laboratory coagulation using nanoiron and sodium water glass. The effectiveness of selected coagulants in the removal of turbidity from water during sedimentation of flakes produced in reaction vessels was investigated. In addition, the effectiveness of individual filtering materials in the removal of turbidity from water containing nanoiron/sodium water glass was investigated. In the end, the results of laboratory tests are compared and evaluated, including photos taken during experiments.

South China Sea: Issues of Chinese U-shaped line
Hofmanová, Lucie ; Romancov, Michael (advisor) ; Karmazin, Aleš (referee)
The bachelor thesis "South China Sea: Issues of Chinese U-shaped line "focuses on a Chinese line called the U-shaped line in the South China Sea. The main task of this thesis is to present the differences in understanding of legal issues between the Chinese academics and their foreign colleagues regarding the U-shaped line, the claims of each state in the South China Sea and their distinction from Chinese claims and the consistency of the U-shaped line with international law. For a comprehensive understanding of the presented issues the first part of work concentrates on historical development of this line and the significance of the South China Sea. Legal concepts and treaties relating to the conflict are explained as well. It involves international law, international maritime law, Note verbale, Declaration on the South China Sea, Treaty of Amity and Cooperation in Southeast Asia, Island of Palmas case and International Court of Justice. The stress is put on the legal aspects and development of this line.

Cyber Security in the United States of America: Assessing the Role of the Department of Homeland Security
Hofmanová, Lucie ; Csernatoni, Raluca (advisor) ; Parízek, Michal (referee)
As one of the major players in cyber security, the United States (U.S.) holds a specific, national security-focused approach towards this field. The most prominent actor in the U.S. within this discipline is the Department of Homeland Security (DHS), which has released its own cyber security strategy four months prior to the overall national strategy. Based on its position in this domain and the specific relationship with the president of the U.S., the thesis aims to explore the DHS and its agenda-setting powers that were used to push its discourse onto the national level. This thesis examines the cyber security strategy of the U.S., specifically the position of the DHS in cyber security, and attempts to determine if this federal department used its influence to mainstream its discourse in the national cyber security strategy. The thesis further analyzes what is the cyber security strategy of the U.S., and if there has been a securitization of this field after 9/11. It draws on a variety of theories and analytical tools, including Hansen and Nissenbaum's securitization theory and agenda setting theory, as well as various methods of political discourse analysis, Fairclough's critical discourse analysis, historical analysis, and process tracing. Ultimately, the thesis reveals the securitizing...

Design and Development of the Network of Points of the Detailed Minor Horizontal Control by the Geodetic nad GPS Methods in the Basin of the Jeninsky Stream
HOFMANOVÁ, Lucie
This Graduation Thesis was elaborated on the following topic: ``Design and Development of the Network of Points of the Detailed Minor Horizontal Control (``DMHC{\crq}q) by the Geodetic and GPS Methods in the Basin of the Jeninsky Stream{\crq}q. The goal of the Thesis was to reconnoitre the part of the basin of the Jeninsky Stream, analyze current level of the minor control in this locality, amend current horizontal minor control in the density for detailed large-scale mapping and locate minor control by the geodetic and GPS methods. The given locality was reconnoitred based on the map basis and geodetic data. Afterwards, I carried out monumentation of new points of the DMHC and then their positional determination by the geodetic and GPS methods. The network of 16 points of the DMHC was created, for this Graduation Thesis was used 8 of them. The electronic total station Leica TCR 407 power was used for the determination by the geodetic method and Trimble 4600LS device was used for the GPS method.
