First experiences with inhalation of nanoparticles by small animals
Mikuška, Pavel; Večeřa, Zbyněk
2012 - Czech
The contribution describes an inhalation chamber constructed for long-term exposure studies of small animals to nanoparticles under strictly controlled conditions (i.e., temperature, relative humidity, illumination, pressure). Nanoparticles were synthetized on-line in a tube flow reactor using metal organic precursors. Experiments proved that the inhalation chamber is suitable for „whole body“ experiments with small animals Příspěvek popisuje inhalační komoru konstruovanou pro dlouhodobé inhalační studie malých zvířat nanočásticemi za přísně kontrolovaných podmínek (tj., teplota, relativní vlhkost, světlo, tlak). Nanočástice byly syntetizovány on-line v trubkovém průtokovém reaktoru z kovových organických prekursorů. Experimenty potvrdily, že inhalační komora je vhodná pro „whole body“ experimenty s malými zvířaty.

Analysis of organic markers in atmospheric aerosol fraction PM2.5 in Ostrava-Radvanice and identification of emission sources
Mikuška, Pavel; Křůmal, Kamil; Kubátková, Nela; Večeřa, Zbyněk
2012 - Czech
Atmospheric aerosols fraction PM2.5 sampled in Ostrava-Radvanice during winter 2012 were analysed for selected organic compounds, so-called molecul markers that serve as indicators of main emission sources of aerosols, especially burning of biomass, fossil fuels, wood, traffic etc. Atmosférické aerosoly frakce PM2.5 odebrané v Ostravě-Radvanicích v zimě 2012 byly analyzovány na obsah vybraných organických sloučenin, tzv. molekulových markerů, které slouží jako indikátory hlavních emisních zdrojů aerosolů, především spalování fosilních paliv, biomasy, dřeva, dopravy atd.

Monitoring of quantitative and qualitative barley proteome changes within different varieties and malting process
Flodrová, Dana; Benkovská, Dagmar; Bobálová, Janette
2012 - Czech
Various European barley cultivars recommended as the varieties suitable for the production of the Czech beer were analyzed in this work. Relative quantification of chosen protein and their comparison was evaluated using the combination of isotopic peptides labeling (iTRAQ) and mass spectrometry. Barley grain proteins were separated by HPLC on the SEC-3 column and chosen identified protein fractions were subsequently used for iTRAQ labeling. V této práci bylo analyzováno několik sladovnických odrůd ječmene jarního, které mají široké uplatnění ve sladovnictví a pivovarnictví a patří mezi doporučené odrůdy vhodné pro výrobu „Českého piva“. Relativní kvantifikace vybraných proteinů a jejich porovnání bylo realizováno pomocí kombinace isotopového značení peptidů (iTRAQ) a hmotnostní spektrometrie. Proteiny obilky ječmene byly separovány pomocí HPLC na koloně SEC-3 a vybrané identifikované proteinové frakce (beta-glukosidasa a beta-amylasa) byly následně použity pro isotopové značení. V obou případech lze sledovat značný nárůst zastoupení daného proteinu v důsledku sladování.

2011 - Czech
Measured and modelled results of ozone deposition and stomatal flux to a Norway spruce forest in locality Bílý Kříž in July and August 2008 were compared. Enhanced concentration of ozone decreased net ecosystem production, especially at higher temperatures and high intensity of global radiation. Srovnání výsledků měření a modelování depozičního a stomatálního toku ozonu u smrku ztepilého v lokalitě Bílý Kříž v červenci a srpnu 2008. Zvýšené koncentrace ozonu snižují čistou ekosystémovou produkci, zvláště při vyšších teplotách a vysoké intenzitě globálního záření.

2011 - Czech
Parallel collection of aerosol particles in size fractions PM2.5 and PM10 and street dust at the same location was performed in Ostrava and Brno during winter and summer 2009 and 2010. Identification of PM sources including resuspended PM and their contribution to overall PM concentration was done by using receptor modelling methods. Aerosoly ve velikostní frakci PM2.5 a PM10 a pouliční prach byly paralelně vzorkovány v Ostravě a Brně během zimy a léta 2009 a 2010. Zdroje aerosolů, včetně resuspendovaného prachu a jeho příspěvku k celkové koncentraci aerosolů, byly identifikovány pomocí metod receptorového modelování.
