Územní aspekty a dlouhodobý monitorovací systém
Česká geologická služba, Praha ; Skořepa, Jaroslav ; Skořepová, Irena ; Krám, Pavel ; Navrátil, Tomáš ; Cudlín, Pavel ; Fottová, Daniela
Monitorovací systém GEOMON koordinovaný ČGS je v současné formě provozován od roku 1994. Ze sítě čtrnácti malých lesních povodí se jednotnou metodikou pořizují vstupní údaje pro výpočet látkových toků ekologicky významných složek. Jedná se o celosvětově uznávaný způsob hodnocení stavu a vývoje přírodního prostředí. Prostředkem k takovému hodnocení je výpočet bilancí, tzn. vstupů a výstupů složek, v přirozených jednotkách biosféry reprezentovaných malým povodím. Vstup do povodí představuje depozice srážkami na volné ploše a pod korunami stromů. jako výstup z povodí je uvažován povrchový odtok. Soubor dat získaný ze sítě malých povodí GEOMON představuje dvanáctiletou řadu dat a vypočtených výsledků, která je hodnocena jako celek zároveň s předchozími ročními soubory od roku 1994.

Deposition of Aerosol Particles on Filter Surfaces
Smolík, Jiří ; Mašková, Ludmila ; Zíková, Naděžda ; Ondráček, Jakub
The simple model showed that the particle penetration and deposition depend on particle size and width of the gap, with the depth of the penetration limited by parallel diffusional deposition on filter surfaces. Smaller particles penetrate faster and deeper resulting in higher particle number concentration of deposited particles but higher mass is transported by larger particles. The results of modelling have been qualitatively confirmed by Ion Chromatography using sulphate as marker for deposited particles.

The Seal of Lantescien in the Context of Criminal Law
KOMÁROVÁ, Vendula
The thesis provides a concise explanation of the notions of confession and the seal of confession and observance of the same by Czech Republic criminal law. The seal of confession is especially provided for by Act No. 3/2002 Coll. on churches and religious societies. In my thesis, I also address the issue of protecting other types of non-disclosure recognized by the Czech Republic. The main topic covers respecting the seal of confession in the context of criminal law. I particularly concentrate on respecting the seal of confession in relation to Sections 167 and 168 of the Criminal Code concerning failure to prevent an offence and failure to report an offence. I also take note of the duty to testify and exceptions to the same. Whereas one of the exceptions{--}prohibition of interrogation{--}does indicate protection of the seal of confession, the other{--}the right to refuse testimony{--}includes no such unequivocal protection. Generally, Czech laws do recognize the seal of confession, and it is impossible to punish observance by priests of the seal of confession.

PIC simulace pravoúhlých a seříznutých štěrbin ve zkušebním limiteru tokamaku TEXTOR
Komm, M. ; Pekarek, Z. ; Pánek, Radomír ; Matveev, D. ; Kirschner, A. ; Litnovsky, A.
In this paper, we present results of Particle-In-Cell simulations of the plasma behavior in the vicinity of gaps in castellated plasma-facing components. We studied gaps in the test limiter of TEXTOR, which is a plasma-facing component designed for studies of impurity transport and fuel retention, mainly via hydrocarbon layer formation. The castellated limiter tiles have been analyzed using the postmortem techniques and first attempts of impurity transport modelling were done using the 3DGAP code [Matveev et al., 2008]. In order to improve the agreement between modeling and experiment, realistic plasma particle flux distribution needs to be included in the code. For this purpose, a series of PIC simulations for varying plasma conditions was performed by using the SPICE2 code [Dejarnac et al., 2008]. Plasma behavior inside the gaps is discussed and semi-empiric characterization via generic fitting procedure is proposed

Experimentální studie depozice aerosolů v testovací komoře.
Hruška, A. ; Dohányosová, Pavla ; Hemerka, J. ; Smolík, Jiří
Particle-phase contaminants in the indoor environment can cause adverse health effects on the general public. It is therefore important to understand the particle behavior. One of the most important processes, which affect the indoor aerosol concentration, is a particle deposition on walls and other inner surfaces. The properties of the aerosol deposition is a main subject of a GACR project conducted in collaboration between the Czech Technical University and The Laboratory of Aerosol Chemistry and Physics of the Institute of Chemical Processes Fundamentals AS CR.
