ACTRIS IMP - účast České republiky v národních výzkumných infrastrukturách a tématických centrech ACTRIS.
Ondráček, Jakub; Váňa, M.; Klánová, J.; Holoubek, Ivan; Ždímal, Vladimír
2019 - Czech
ACTRIS (The Aerosol, Clouds and Trace Gases Research Infrastructure) je panevropskou výzkumnou infrastrukturou, jejímž hlavním cílem je tvorba vysoce kvalitních dat a podávání informací o krátkodobých složkách atmosféry a o procesech vedoucích ke změnám těchto složek v přírodním a kontrolovaném laboratorním prostředí. ACTRIS je dlouhodobou aktivitou více než 100 partnerských organizací po celé Evropě, jejichž cílem je integrace, harmonizace a distribuce vysoce kvalitních vědeckých výstupů poskytovaných nejlepšími pracovišti atmosférického výzkumu v (prozatím) 22 evropských zemích. ACTRIS je logickým pokračováním 15-tiletého rozvoje velkých výzkumných infrastruktur financovaného členskými státy a evropskou komisí (EC) prostřednictvím programu výzkumných infrastruktur (Research Infrastructure programme) zahrnujících např. Projekty EARLINET, EUSAAR, CREATE a CLOUDNET. ACTRIS (The Aerosol, Clouds and Trace Gases Research Infrastructure) is pan-european research infrastructure, having the main goals in provision of high quality scientific data and provision of information about short-lived atmospheric components and processes leading to changes in these components in natural and controlled laboratory environment. ACTRIS is a logical continuation of 15-years development of large research infrastructures being funded by member states and European Commission through the Research Infrastructure Programme (including e.g. EARLINET, EUSAAR, CREATE and CLOUDNET).

Původ znečištění ovzduší na základě ročního měření PM2.5 a PM10 na dvou městských pozaďových stanicích v Praze.

Hmotnostní koncentrace atmosférického aerosolu (particulate matter – PM) ve městech odpovídá součtu koncentrace naměřené na pozaďových stanicích a rozdílu mezi městskou a pozaďovou stanicí. Z tohoto důvodu je při vysokých pozaďových koncentracích PM výsledek opatření snižujících míru emisí malý. Většina uváděných episod zvýšených koncentrací PM v zimě ve městech střední Evropy je způsobena zdroji lokálního nebo regionálního původu ze spalování uhlí a/nebo biomasy za účelem vytápění. Zlepšení kvality ovzduší ve městech je možné za předpokladu pochopení kauzalit především pokud se jedná o atmosférický aerosol a jeho koncentrace, zdroje a původ.\nCílem práce bylo určit původ znečištění ovzduší v Praze na základě ročního paralelního měření atmosférického aerosolu na dvou městských pozaďových stanicích. The particulate matter (PM) mass concentration in cities corresponds to the sum of the concentrations measured at the background stations and the difference between the city and background stations. For this reason, at high background concentrations of PM, the result of emission reduction measures is low. Most of the reported episodes of increased PM concentrations in winter in central European cities are caused by sources of local or regional origin from the combustion of coal and / or biomass for heating purposes. Improvement of air quality in cities is possible provided that causality is understood, especially when it comes to atmospheric aerosol and its concentration, sources and origin.\nThe aim of the work was to determine the origin of air pollution in Prague on the basis of one year parallel measurements of atmospheric aerosol at two urban background stations.\n\n

Metabolomics Study of the Association between Pancreatic Cancer and Diabetes Mellitus.
Michálková, Lenka; Horník, Štěpán; Sýkora, Jan; Habartová, L.; Setnička, V.
2019 - English
In our study, 1H NMR metabolomics was employed to plasma samples of pancreatic cancer patients, individuals with long-term diabetes mellitus type 2 (lasting more than 5 years) and healthy controls. The NMR analyses were followed by establishing a statistical model based on principal component analysis and discriminant analysis. The aim was to discover differences between these groups and to define a potential biomarker panel. The statistical evaluation of metabolomics-based profiles provided high values of sensitivity and specificity. Subsequently, plasma samples of the risk group, specifically patients with recently diagnosed diabetes mellitus with a duration of <3 years (possible T3cDM), were analysed and the possibility of PC development was predicted. The achieved results showed strong potential of 1H NMR metabolomics to establish a biomarker panel that would facilitate the early diagnosis of PC and the possibility identify diabetic individuals, who are at risk of developing PC.

Hydrodynamic Behavior of Large Bubbles inSlot Channels.
Ezeji, Kingsley
2019 - English
We present the results of experimental investigation on the dy-namics of air bubbles rising in stagnant or co-flowing liquid insidean inclined rectangular channel. Variable channel geometry (withadjustable height𝐻, perimeter𝑃 = 2(𝐻 + 𝑊), inclination𝛼, and orien-tation – flat𝐻 < 𝑊or tall𝐻 > 𝑊) enabled us to evaluate the influenceof different operation parameters on the bubble shape and velocity. Measurements of the rise velocity of large Taylor bubbles (𝑈TB) werecarried out by using a high-speed video camera system and an imageprocessing technique.

Metody separace mikroplastů z vody.
Kulaviak, Lukáš; Šyc, Michal; Růžička, Marek; Zedníková, Mária
2019 - Czech
Výzkumná zpráva se zabývá aktuálním tématem problematiky výskytu mikroplastů v životním prostředí, zejm. ve vodách. Jedná se o dosud málo zmapovanou záležitost, kdy malé částice plastů znečišťují prostředí a mají dosud nedostatečně prozkoumaný vliv na životní formy. Důležitým krokem je účinná separace mikroplastového odpadu pro jeho následnou likvidaci. Proto jsou popsány různé separační metody. The research report concerns the important current topic of microplastics occurrence in the environment, namely in waters. It is a little developed subject to understand how the fine particles contaminate our world and affect its various inhabitants. The key step is their effective separation needed for their further treatment. Therefore, several possible separation methods were described.
