Selection of the risk sources and their assessment in the explosives operations
Hajný, Vít ; Tabas, Marek (referee) ; Kotek, Luboš (advisor)
The Master´s thesis concerns with the choice of sources of risks and their evaluation with storage of explosives. It is divided into four parts. The first two parts are research ones and they deal with accesses to the choice of sources of risks with storage of explosives and statutory requirements for explosives, their storage, manipulation and transport and then with the buildings, which the explosives are stored in. In the next part the accesses to selection and evaluation of sources of risks in real storage units are chosen and compared. In the final part there is the chosen methodology used in case studies.
Modern detection methods of energetic materials
Šesták, Jozef ; Bednařík, Karel (referee) ; Friedl, Zdeněk (advisor)
The review of modern detection methods of explosives was composed. Firstly the thesis deals with the detection methods commonly used in forensics science such as gas chromatography, mass spectrometry, ion mobility spectrometry, Raman spectroscopy and mainly their innovations. Then the thesis is focused on simple but very sensitive methods using fluorescence and chemiluminescence. At the end a methods as the results of a latest research are mentioned. The main of them are micro cantilever sensors and differential reflectometry. Security and counterterrorist warfare is main point of thesis.
Detection methods of energetic materials
Procházka, Michal ; Diviš, Pavel (referee) ; Friedl, Zdeněk (advisor)
A research on current methods of detection of explosives and related materials was made. At first the thesis studies methods of detection and analysis of explosives including chromatographic methods (TLC, GC, HPLC, IC), mass spectrometry and its variations, ion mobility spectrometry and infra-red spectroscopy. Next the attention is placed on detection of explosives in solid phase by X-ray detection, nuclear magnetic and quadrupole resonance and thermal neutron activation. Practical applications of these methods are of great importance in this thesis as well as their usage in the counterterrorist fight.
Fast separation of explosives by high performance liquid chromatography
Šesták, Jozef ; Vávrová, Milada (referee) ; Kahle,, Vladislav (advisor)
The topic of the diploma thesis is fast separation of explosives by HPLC and development of miniaturized liquid chromatograph for application in a handheld explosives detection device. In this work the retention of some nitrated explosives and selectivity in reversed phase system as a function of mobile phase composition is studied while methanol, acetonitrile and acetone as an organic solvent is used. Best selectivity and good retention can be observed in methanol mobile phase. Acetonitrile and acetone are not suitable for fast isocratic separation of mixture containing pentaerythritol tetranitrate because of its strong retention. Efficiency and permeability of monolithic column (Chromolith CapRod RP-18e) and columns filled with superficially porous particles are compared (Kinetex 2,6 µm C-18, Poroshell 120 SB-C18). Monolithic column with satisfying efficiency and high column permeability is the most suitable solution for fast separation of explosives. Assuming use of explosives detection device in different conditions the separation was optimized on temperature 50 °C. Under these conditions the 35% v/v methanol gives good retention and selectivity. For very fast scan analysis of pentaerythritol tetranitrate or other nitroaromatics use of 70% v/v acetone mobile phase is suitable. Construction of miniaturized liquid chromatograph that enables preconcentration of explosives from aqueous solutions and fast separation in less than 1 minute is described. This concept will be incorporated into the handheld explosives detection device where the explosives vapor will be absorbed into the water and after the separation detected by chemiluminescence.
Storage and transport of ammunition and explosives according to regulations of Czech Army and in civilian sector.
LÁTR, Vladimír
The bachelor thesis deals with the storage and transport of ammunition and explosives in the Czech Republic. This problem was most spread in the Czech Republic after the unfortunate explosion of the ammunition warehouse in Vrbětice in 2014. Explosions of ammunition depots are devastating and therefore they are so dangerous for their surroundings. Explosion can never be eliminated 100%. Explosions occur in the world and in our country. Therefore, the laws, regulations and decrees for the storage of ammunition and explosives are amended to minimize this risk. The theoretical part at the beginning focuses on the history of ammunition depots and the results of explosions. The next chapter focuses on legal regulations for fire arms, ammunition and ammo. For their content, they were divided into seven subchapters, with a comprehensive overview of all legislation relevant to the issue. In the next chapter there are mentioned the regulations of the Czech Army and in the last chapter there are clarified the basic terms of bachelor thesis - dangerous goods, ammunition and explosives. In the practical part of the bachelor thesis there is analyzed the accumulated literature with a view of the civil sector. The issue of ammunition and explosives had to be divided into two chapters. Both of them deal with ammunition and explosives but each has different legislation. The first chapter deals with the issue of the transport of ammunition and explosives and the second one solves objects for its storage. The analysis analyzed and compared the regulations in force in the Czech army and the research question was answered "Are the main differences in the legal regulations on the transport and storage of ammunition and explosives within the ACR and the civil sector?" At the end of the bachelor thesis, the differences between the storage of ammunition and explosives in the Czech army and the civilian sector are summarized. And recommendations for the following legislation were given.
International trade with explosives from the perspective of Czech law and European union law
Neustupný, Martin ; Pauknerová, Monika (advisor) ; Pfeiffer, Magdalena (referee)
The aim of this thesis is to realize description and analysis of the legal regulation of international trade with explosives, concentrated on the European community law and the Czech law. The thesis is focused on public law regulations of this issue with consideration of all partial aspects, including historical connections, because the legal regulations of explosives have several hundred years lasting history. The introduction describes the basic historical changes of the explosives issue from both the technical and legal points of view, focusing on Czech and British legal regulation. This part is followed by the theoretical categorization of legal regulation of the trade with explosives in the system of international trade law and by a survey of most important legal rules of international, European community and Czech law, regulating this legal branch. In the next chapters my thesis goes on with the analysis of valid legal rules, relating to individual partial issues such as a definition of the subjects authorized to explosives treatment, legal regulation of international trade with explosives for civilian use, international trade with explosives for military use and launching of explosives on European market. The prevention of the misuse of explosives for criminal delicts is represented in this thesis by...
