Construction and characterization of recombinant adenylate cyclase toxoid of bacterium Bordetella pertussis carrying mycobacterial antigen TB7.7
Mikulecký, Pavel ; Staněk, Ondřej (advisor) ; Vopálenský, Václav (referee)
Bacterium Mycobacterium tuberculosis is an etiological agent of a deadly disease called tuberculosis that presents a global problem. According to The World Health Organization there are more than 2 billions people infected with latent tuberculosis all over the world. There is still need of specific, sensitive, quick and economic available method for identification of infected individuals. Currently in vitro blood tests are considered to be the best way of diagnosis. They are based on restimulation of specific T lymphocytes by mycobacterial antigens derived from virulent strains. There are several different approaches for enhancing of direct antigen delivery into antigen presenting cells and promising one is a genetically detoxified adenylate cyclase toxin (CyaA) of bacteria Bordetella pertussis. The main aim of the thesis includes construction and subsequent characterization of biological properties of CyaA protein carrying specific mycobacterial antigen TB7.7 in translocating domain. Here is shown that fusion protein CyaA-TB7.7 can form cation selective pores in target cell membranes and is able to deliver antigens into the cytosol of APC to be presented on surface with molecules MHC class II. Genetically detoxified CyaA- TB7.7 protein will be used to supplement current approaches such as also in vitro...

Centralized multirobot system
Staněk, Ondřej ; Obdržálek, David (advisor) ; Mráz, František (referee)
Title: Centralized multirobot system Author: Ondřej Staněk Department: The Department of Software Engineering Supervisor: RNDr. David Obdržálek Supervisor's e-mail address: David.Obdrzalek@mff.cuni.cz This thesis focuses on design and implementation of a centralized multi-robot system. A host computer (or cellphone) controls several tiny PocketBot2 mobile robots. These robots feature various sensors. They can perform line-following and they are equipped with a system for detecting obstacles and other robots. Although the PocketBot2 robots were designed and built within the frame of this thesis, the core of the thesis itself lies in the software. For the PocketBot2 hardware, an embedded control system was designed and implemented. It interfaces robot's sensors and carries out basic movement commands. Bluetooth technology is used for wireless data transfer between robots and the host. In the host, a multi-platform control library was implemented. It provides access to sensors of individual robots and controls their movement. The library ensures convenient interface for implementing centralized multi-robot algorithms. Keywords: robot, library, PocketBot, Bluetooth, Java

Historical and present anthropogenic gradients in landscape
Staněk, Ondřej ; Vojta, Jaroslav (advisor) ; Klinerová, Tereza (referee)
My bachelor thesis is concerned in determining and classification of main anthropogenic influences in various ecosystems. Intensity and direction of landscape transformations such as nutrient income, terrain changes, disturbance, biomass removal or fragmentation is discussed and evaluated. Other landscape factors taking part in ecosystem endurance like different structure and pH of soils or various microclimatic conditions are also taken in notice. It seems that intensity of human influence varies depending on it's nature and it is difficult to propose a linear scale of these changes. From this point of view German hemeroby concept is discussed as possibly suitable scale of human influence.

Visual Programming Backend for a Mobile Robot
Staněk, Ondřej ; Obdržálek, David (advisor) ; Bednárek, David (referee)
Title: Visual Programming Backend for a Mobile Robot Author: Bc. Ondřej Staněk Department: The Department of Software Engineering Supervisor: RNDr. David Obdržálek, Ph.D. Supervisor's e-mail address: David.Obdrzalek@mff.cuni.cz Abstract: In this work, the author designs and implements a solution for programming small mobile robots using a visual programming language. A suitable visual programming front-end is selected and back-end layers are created that allow execution of the program in a mobile robot. The author designs and implements a virtual machine that runs alongside the original robot firmware on an 8-bit microcontroller with limited resources. A code generator layer compiles the visual representation of the program into a sequence of bytecode instructions that is interpreted on board of the mobile robot. The solution supports typical features of procedural programming languages, in particular: variables, expressions, conditional statements, loops, static arrays, function calls and recursion. The emphasis is put on robustness of the implementation. To verify and maintain code quality, methods of automated software testing are used. Keywords: visual programming language, virtual machine, mobile robot, Blockly Powered by TCPDF (www.tcpdf.org)

Recombinant preparation of TEAD transcription factor.
Lišková, Růžena ; Novák, Petr (advisor) ; Staněk, Ondřej (referee)
Recombinant preparation of TEAD transcription factor (abstract) The TEAD family transcription factors play an important role during devolopment of organisms, where their main purpose is to regulate organ size by activating expression of proteins involved in cell growth and differentiation and apoptosis inhibition. TEAD proteins activity is regulated by signalling pathways and interactions with coactivators. Disregulation of these mechanisms can lead to development of tumors, which is the reason why TEAD proteins became an interesting target for development of new anticancer drugs based on inhibiting their activity. There are several possibilities how to inhibit activity of a transcription factor including blocking its bond to DNA. To design a new drug that blocks transcription factors binding to DNA the structural basis of interaction of these two molecules has to be known first. In this thesis the DNA binding domain of human protein TEAD1 was prepared using the technique of recombinant expression in bacteria E. coli. Suitable conditions of protein production were found and the DNA binding domain of TEAD1 protein was purified so it will be possible to use it for structural analysis of its intraction with DNA.

Czech nuclear law
Staněk, Ondřej ; Stejskal, Vojtěch (advisor) ; Sobotka, Michal (referee)
The topic of this thesis is Czech nuclear law. The purpose of the nuclear law is to regulate the conditions of use of nuclear energy and ionizing radiation in order to ensure protection of people and environment from the adverse effects of ionizing radiation. Because of highly technical nature of nuclear law, the first chapter is devoted to possibilities of use of ionizing radiation, and to outline few of relevant technical terms. The second chapter of this thesis deals with international cooperation in the area of use of nuclear energy and ionizing radiation. The third and fourth chapters are devoted to Czech nuclear law with main focus on environmental aspects. While the third chapter defines the principles and tools of environmental protection in the field of nuclear law and introduces the structure of legal norms in this area, the fourth chapter analyzes the regulation of specific activities related to the use of ionizing radiation. Included are chapters concerning construction of nuclear facilities, transport of radioactive substances, decommissioning of nuclear facilities and radioactive waste management. Disregarded is neither regulation of liability for nuclear damage. In conclusion, the thesis highlights weak points of the legislation and delineates possible solutions de lege ferenda,...

Influence of military activities on vegetation diversity in Doksy region
Staněk, Ondřej ; Vojta, Jaroslav (advisor) ; Volařík, Daniel (referee)
The thesis focuses on description of specific area of Doksy region, situated in northern Bohemia. This region was affected by fifty years of military management. Vegetation composition, species richness and several environmental characteristics were measured and statistically tested to determine the effect of military area on landscape and vegetation. No significant difference in species richness, but important changes in species composition were discovered. Also the environmental (soil) characteristics of the area were probably changed by the military history of landscape. There were no major changes in Beta diversity uncovered, probably because of different management leading to the same resulting changes applied in the landscape. Also four invasive plant species were found in high numbers present in the area connected with past military land-use.
