Microscopy 2008
Hozák, Pavel
Two-day conference responding to novel trends in light and electron microscopy and their impact on researchers in the Czech Republic and Slovakia. Contributions were presented in biomedical as well as physics and material science fields. The Conference was held in a sports area in the heart of the Czech-Moravian Heights and was closed by an opulent rout with wine degustation.

IS/ICT organization operating in healthcare
Machač, Šimon ; Potančok, Martin (advisor) ; Voříšek, Jiří (referee)
Bachelor thesis is focused on IS/ICT organizations, which contribute to the development of electronic healthcare in the Czech Republic.Purpose of this thesis is to present individual organisations which partake in the development of electronic healthcare and to analyse relationships between these organisations.Introductory part contains a classification system. Every studied organisation will be classified into one of the categories that are contained in the classification system. Following part ad-dresses introduction of individual organisations and their partners with whom they cooperate. Last, and most important, part is focused on analysing how organisations are tied through pro-jects and conferences which they attend.

Treatment of Flue Gas from Waste Incineration by Sodium and Calcium Based Sorbents.
Zach, Boleslav ; Pohořelý, Michael ; Šyc, Michal ; Svoboda, Karel ; Punčochář, Miroslav
This paper is focused on properties of sodium and calcium based sorbents in relation to simultaneous dry flue gas treatment from SO2, HCl, NOx, solid particles, and polychlorinated dibenzodioxins and dibenzofurans (PCDD/F). The most important differences between the two sorbent types are: the effect of temperature and moisture of flue gas on the sorption process, reactivity towards individual acid components in the flue gas (thermodynamic equilibrium and kinetics), and solubility of air pollution control residues.

Comparison of Atmospheric Aerosol Volatility at a Suburban and Rural Measurement Site.
Kubelová, Lucie ; Vodička, Petr ; Schwarz, Jaroslav ; Makeš, Otakar ; Ždímal, Vladimír
One of the most important characteristics of atmospheric aerosols is their volatility. Volatility affects the formation, life time, and removal of aerosol particles (Huffman et al., 2009). Accurate description of volatility of atmospheric aerosols can lead to a better identification of their sources and it is also crucial for models incorporating condensation and aging of aerosols. However, there is still a lack of knowledge regarding aerosol properties such as volatility especially in case of organic aerosols. To increase our understanding of aerosols volatility, we have performed summer (21.8.-2.10.2012; 17.6.-18.8.2014) and winter (19.2.-28.5.2013; 9.1.-13.3.2014) measurement campaigns with a thermodenuder at a suburban site in Prague Suchdol and at a rural site Košetice, respectively.

Generation of NPS for Exposure Experiments from Copper Acetylacetone.
Moravec, P. ; Schwarz, J. ; Vodička, P. ; Kupčík, Jaroslav ; Švehla, J.
Particles containing copper are emitted from smelters, iron foundries, power stations, and municipal incinerators (WHO, 1998) and also from brake linings during breaking, Kukutschová et al. (2011). Nanoparticles (NPs) of copper are ingredients in polymers, inks, and bioactive coatings inhibiting the growth of microorganisms, Cioffi at al. (2005), and CuO NPs has been used in antimicrobial textiles, Gabbay and Borkow (2006), therefore they can be easily inhaled. Even though CuO NPs were found highly toxic, Karlsson et al. (2008), in vivo studies of their toxicity are still rather rare. In this work we tested a method of long lasting nanoparticle generation from copper acetylacetonate (CuAA) for use in follow up exposure experiments with laboratory animals. The exposure chamber for inhalation experiments was constructed in the Institute of Analytical Chemistry AS CR (Večeřa et al., 2011) and some methods of NPs generation for these experiments were already tested in our laboratory (Moravec et al., 2015, Moravec et al., 2016).

I/O Aerosol in Kindergarten - Case Study.
Ondráček, Jakub ; Talbot, Nicholas ; Cusack, Michael ; Vodička, Petr ; Ždímal, Vladimír ; Schwarz, Jaroslav
In last decades, people spend more and more time indoors. When various indoor sources are present, the indoor air quality is driven mainly by these sources. Without the presence of significant indoor sources, the situation is very different and the concentration of aerosol particles in indoor environment follows behavior of outdoor particles (taking into account losses of aerosol particles due to deposition on indoor surfaces and during penetration indoors. Many epidemiological studies show direct link between dose/exposition to fine (< 1µm) and ultrafine (< 100 nm) particles and adverse health effects. With regards to the fact that indoor environment is besides the adults occupied usually also by kids in longer time periods, it is very important to study the indoor environment in a great detail and to understand the behavior of aerosol particles indoors. In the case of the kids being exposed to the indoor aerosol particles, the adverse health effect can be more pronounced and the consequences more dangerous. Nevertheles, at the same time it is necessary to monitor the outdoor environment as well by observing its changing daily pattern and trying to identify the possible sources of outdoor air pollution.\n

Ammonia and Ammonium Nitrate in Archives
Mašková, Ludmila ; Smolík, Jiří ; Ďurovič, M. ; Součková, M.
Ammonia in libraries and archives can damage stored materials such as pigments and metals (Grzywacz, 2006) and mediate microbial decomposition (Petushkova and Lyalikova, 1986). The aim of this study was to investigate concentrations and sources of ammonia in the indoor air of five different types of archives, and to establish the relationship between the indoor and outdoor environments.

Properties of Aerosol, Produced by Laser Ablation of Standard Materials for ICP-MS Analysis.
Holá, M. ; Nováková, H. ; Ondráček, Jakub ; Vojtíšek, M. ; Kanický, V.
Laser ablation (LA), together with inductively coupled plasma mass spectrometry (ICP-MS) as a detection system, has become a routine method for the direct analysis of various solid samples. The product of laser ablation contains a mixture of vapour, droplets and solid particles. All components are finally transported to a plasma by a carrier gas as a dry aerosol including mainly agglomerates of primary nanoparticles. In general, characterisation of aerosols by their particle size distribution (PSD) represents indispensable tool for fundamental studies of the interaction of laser radiation with various materials. The particle size distribution of dry aerosol originating from laser ablation of standard material was monitored by two aerosol spectrometers – Fast Mobility Particle Sizer (EEPS) and Scanning Mobility Particle Sizer (SMPS) simultaneously with laser ablation - ICP-MS analysis.\n
