Source apportionment of atmospheric aerosol fraction using by highly time resolved characterisation
Pokorná, Petra
The effective air quality management in the heavy polluted areas has to be based on high-quality monitoring with properly designed monitoring network and targeted measurements, which provided information required to source apportionment. The thesis aim was to apportion sources of atmospheric aerosol based on highly time resolved data of mass concentration of size segregated aerosol, its temporal and spatial variability, elemental composition, OC/EC and size distribution of carcinogenic polyaromatic hydrocarbons. Sampling campaigns went during winter and summer in small settlement Březno by Chomutov, residential area Ostrava - Radvanice a Bartovice and Mladá Boleslav in the years 2008 - 2010, 2012, 2013. We determined mass concentrations of PM10, PM1-10, PM1.15-10 and PM0.15-1.5 and their size fraction ratios. Based on the size ratios, the source apportionment of fine fraction (PM0.15-1.15) with focus on PM0.34-1.15 is crucial. We examined seasonal and spatial variability of PM10, PM.2.5, PM1 and PM1-10. Based on the examination, we obtained representative highly-time resolved data with regards to season and sampling locality. We analysed dynamic of size distribution of particle-bond eight carcinogenic polycyclic hydrocarbons. Based on the results the source apportionment of PM0.34-1.15 is crucial....

In vitro effect of flavonoids on activity of selected biotransformation enzymes in intestinal cell lines
Pokorná, Petra ; Szotáková, Barbora (advisor) ; Matoušková, Petra (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Petra Pokorná Supervisor: Doc. Ing. Barbora Szotáková, Ph.D. Title of diploma thesis: In vitro effect of flavonoids on activity of selected biotransformation enzymes in intestinal cell lines Anthocyanins belong to a class of flavonoids which are part of major natural pigments in plants. They are considered to be very beneficial for the human organism. Anthocyanins are widely consumed as fruits, vegetables and red wine and they represent significant constituents of dietary supplements. The popularity of dietary supplements with high concentrations of flavonoids is still increasing, but in addition to positive effects on human health it can also have side effects influence drug metabolizing enzymes and thus affect either desirable or undesirable effects of many drugs. In this thesis in vitro effect of some anthocyanidins (cyanidin, delphinidin, malvidin, pelargonidin) on the proliferation of the intestinal cell line Caco-2 was investigated using the assay of metabolic activity (MTT) and determination of the integrity of the cytoplasmic membrane of cells (neutral red). Then was studied their effect on the activity of selected biotransformation enzymes: glutathione S-transferase (GST),...

Source Apportionment of Atmospheric Aersol Using by Highly Time Resolved Characterization.
Pokorná, Petra ; Hovorka, J. ; Klán, M. ; Křůmal, Kamil ; Mikuška, Pavel ; Hopke, P.K. ; Ždímal, Vladimír
The effective air quality management in the heavy polluted areas has to be based on high-quality monitoring with properly designed monitoring network and targeted measurements, which provided information required to source apportionment. The study aim was to apportion sources of atmospheric aerosol based on highly time resolved data of mass concentration of size segregated aerosol, its spatial variability, elemental composition and OC/EC at three localities in the Czech Republic in the years 2008 – 2010, 2012, 2013. According to the size fractions ratio arose the importance of PM1 source apportionment because of PM0.15-1.15 mean ratio to PM10, which comprised 85 % at the monitoring localities primarily in winter. The main sources of coarse fraction in winter were coal and biomass combustion in Březno by Chomutuv a Mladá Boleslav and road dust re-suspension in Ostrava-Ravanice and Bartovice. In summer dominated soil re-suspension and primary biological – bioaerosol in Březno by Chomutuv. The dominated source of fine fraction was in winter coal combustion Ostrava-Ravanice and Bartovice and biomass burning in Mladá Boleslav. From the above mentioned results arose, that the highly time resolved data are suitable for source identification of size segregated atmospheric aerosol and enable to evaluate representativeness of monitoring station location and measurement campaign.

English translation equivalents of Czech prepositions "s" and "na" (in parallel electronic texts)
Pokorná, Petra ; Malá, Markéta (advisor) ; Klégr, Aleš (referee)
The aim of this study is to analyze and describe the English translation equivalents of two Czech prepositions 'na' and 's' (including its vocalized form 'se') in texts of contemporary Czech fiction and their English translations. The study is divided into three major parts: a theoretical overview, an analysis and a conclusion. The theoretical survey consists of two parts, in which the syntactic and semantic characteristics of prepositions in general are dealt with and the status of prepositions in Czech and English is compared. The first, syntactic part provides an overview of the syntactic functions of the prepositional phrases. The semantic part describes the treatment of prepositional meanings in Czech and English grammars and focuses on the meanings attributed to 'na' and 's' in Czech grammars and monolingual and bilingual Czech-English dictionaries. The analytical part of the present paper will be preceded by a brief specification of the data on which the analysis was based. The analysis itself is divided into two parts, each of which comprises two subsections. The first analytical part compares the syntactic functions of the Czech prepositional phrases and their English counterparts, the first subsection providing an analysis of the preposition 'na', the other examining the preposition 's/se'. In the...

Nursing Care of the Patient with Colorectal Cancer
Pokorná, Petra ; Vytejčková, Renata (advisor) ; Vobořil, René (referee)
Cílem mé bakalářské práce je zpracování případové studie ošetřovatelské péče o nemocného, který byl hospitalizován na chirurgickém oddělení v jedné z pražských nemocnic s diagnózou karcinom recti. V této studii jsem se věnovala 40-ti letému pacientovi, který byl přijat k resekci rektosigmoidea. Pacient souhlasí s tím, že informace o jeho nemoci budou použity při zpracování této práce. V klinické části se věnuji charakteristice onemocnění, anatomii a fyziologii tlustého střeva a rekta. Dále se zabývám patofyziologií nádorů, klinickým obrazem nemoci a základními vyšetřovacími metodami vedoucí k diagnóze kolorektálního karcinomu, prognózou a možnostmi prevence. Dále jsou zde uvedeny základní údaje o pacientovi, údaje z lékařské anamnézy a vyšetření, která byla rozhodující indikací k operačnímu výkonu. Následuje stručný průběh hospitalizace. Ošetřovatelská část zahrnuje stručnou charakteristiku ošetřovatelského procesu, zhodnocení nemocného podle modelu Majory Gordonové, stanovení aktuálních a potencionálních diagnóz, realizaci a hodnocení ošetřovatelské péče. Informace o nemocném jsem zaznamenala do formuláře zpracované pro potřeby výuky v oboru ošetřovatelství na 3. LF UK v Praze a ošetřovatelskou anamnézu jsem zaznamenala do formuláře z nemocnice ÚVN. Ošetřovatelské diagnózy jsem stanovila z analýzy...

Corporate Culture in the Selected Organizations
POKORNÁ, Petra
The aim of this bachelor's thesis titled Corporate Culture in the Selected Organizations is the specification of company culture issues in designated organizations. I have divided this thesis into two parts, theoretical and practical. I established the theoretical part on the basis of literature dealing with company culture issues. Here I defined the term company culture and related concepts. In the practical part, I analyzed company culture in selected organizations. The results were obtained using a questionnaire VSM 94&2013 of Geert Hofstede. Unguided interviews were carried out for greater quality of this research, which was also supplemented by observation. The acquired data were evaluated on the basis of Geert Hofstede formulas. In conclusion and on the basis of acquired data, I have proposed the changes in company culture in the selected organizations.
