Selected facts of cases of traffic violation in the exercise of public administration
Márton, Michal ; Kopecký, Martin (referee) ; Prášková, Helena (referee)
Rigorous thesis brings the focus on selected facts of cases of traffic violation by author, who deals with this agenda for 6 year term. Rigorous thesis deals with the problems connected with aplication and interpretation of laws. Text is devided into four basic parts: historical context of laws regulates traffic violation, the term of "offence" and it's relationship between other violation of law such as criminal act and administrative offence, selected facto of cases of traffic violation, conclusion. Text is completed by model cases and references to actual decision of Supreme administrative court, criminal senat of Supreme court and Constitutional court of the Czech republic. In the case of application problem, author brings the comparation of legal acts of Czech republic with Slovak republic and Poland, which are the states with high number of traffic violation as well and also brings the proposals for "de lege ferenda" solution.

Lab-made Sensors Based on Boron-doped Diamond for Determination of Herbicide Linuron

Voltammetric behaviour of substituted urea herbicide linuron (LIN) was investigated using two types of boron-doped diamond electrodes (BDDE): commercial BDDE and lab-made sensors based on boron-doped diamond (LM-BDDE). Various methods like cyclic voltammetry (CV), direct current voltammetry (DCV) and differential pulse voltammetry (DPV) were examined. It was found that LIN provides one oxidation peak using all of the tested working electrodes and the highest current response was recorded in the acidic media. Thus, Britton-Robinson (B-R) buffer of pH 2 was used as a supporting electrolyte. Parameters of DPV were optimized and the low limits of detection (LOD) were reached 1.41×10−7 M for commercial boron-doped diamond electrode and 8.81×10−9 M, respectively, which represents the lowest LOD obtained for lab-made boron-doped diamond electrodes.

Ižák, Tibor ; Babchenko, Oleg ; Varga, Marián ; Potocký, Štěpán ; Marton, M. ; Vojs, M. ; Domonkos, Mária ; Kromka, Alexander
This study deals with the nucleation and growth of CVD diamond films on Si substrates. In nucleation part two different nucleation methods were studied: (i) the bias enhanced nucleation (BEN) and (ii) ultrasonic seeding. In the case of BEN, (i) the nucleation time and (ii) the influence of bias voltage were studied. For ultrasonic seeding the effect of different solutions of ultradisperzed detonation nanodiamond (UDD) powder with metal particles on the nucleation efficiency and growth process was investigated (i.e. diamond powder, nanosized Ni, microsized Co and Y metal powders).
