Energy dispersive X-ray spectroscopy of doped PVDF fibers
Smejkalová, Tereza ; Papež, Nikola (referee) ; Sobola, Dinara (advisor)
Tato diplomová práce zkoumá flexibilní materiál k produkci elektřiny založený na piezoelektrickém polymeru Polyvinylidenfluorid (PVDF). Inkorporací piezoaktivní keramiky lze vlastnosti piezoelektrického polymeru PVDF významně zlepšit a převést na užitečnou elektrickou energii. PVDF byl vytvořen elektrostatickým zvlákňováním do vláken o tloušťce 1,5-0,3 µm a poté studován různými analytickými metodami. Tato práce nabízí popis elektrostatického zvlákňování, přípravu vzorků a teoretický úvod do analytických metod, kterým byly vzorky podrobeny. Morfologie a distribuce nanostrukturované keramiky do polymerní matrice PVDF byla pozorována použitím skenovací elektronové mikroskopie (SEM) a energiově disperzní spektroskopie (EDX). Pro tvorbu fáze a podrobné fázové složení byly vzorky charakterizovány infračervenou spektroskopií s Fourierovou transformací (FTIR). Práce také obsahuje analýzu s použitím Ramanovy spektroskopie, metody používané k identifikaci a porovnání chemických sloučenin. Elektrické vlastnosti byly studovány dielektrickou spektroskopií a je poskytnuta korelace se složením. Jednotlivé komponenty dotovaných vláken jsou charakterizovány a vyhodnocovány v souvislosti s jejich budoucím využitím v senzorech.

Mass Spectrometry
Smejkalová, Tereza ; Baumgartnerová, Alena (referee) ; Krhutová, Milena (advisor)
Hmotnostní spektrometrie je metoda analytické chemie používaná k analýze organických i anorganických sloučenin. O tomto tématu se běžně dozvídáme z prací týkajících se chemie, protože tato metoda může být využita k identifikaci mnoha druhů sloučenin. Vlastní fungování přístrojů používaných v hmotnostní spektrometrii ale musíme hledat ve specializovaných knihách zaměřených na tuto metodu a tyto informace jsou obvykle popsané velmi komplikovaně. Proto jsem se rozhodla napsat práci, která uvádí základní informace o hmotnostní spektrometrii z pohledu elektrotechniky, srozumitelně popisuje jednotlivé fáze této metody a která nebude zaměřena na výstup analýzy, ale na technický proces. V druhé části práce se věnuji praktickému použití hmotnostních spektrometrů v průmyslu při testování těsnosti produktů a typům testování těsnosti, vysvětluji důležité termíny a detailně popisuji spektrometr LDS3000. Mým záměrem je ukázat, že tato metoda je skutečně zajímavá a poutavá a chci ji proto představit ostatním.

Nursing care for a woman with pre-eclampsia, perinatological results in relation to creatinine levels in maternal blood
Šmejkalová, Tereza ; Koucký, Michal (advisor) ; Čábela, Radek (referee)
Pre-eclampsia (PE) is a serious multi-organ disease complicating pregnancy. It occurs in 2-8% of pregnancies worldwide and approximately 50,000 women die from its consequences each year. This bachelor's thesis summarizes the theoretical knowledge of PE, - specifically the etiopathogenesis, classification and symptoms of the disease, treatment management, likely complications and other aspects that are important in nursing care. The practical part of the thesis deals with the use of serum creatinine (S-creatinine) levels to determine the severity of the patient's condition and the likely consequences for the foetus. The main objective of the thesis was to find a correlation between maternal S-creatinine levels prior to delivery and perinatal outcomes. The sub-objective was to monitor serum urea (S-urea) levels in relation to the length of pregnancy. Our hypothesis was that as the mother's antepartum S-creatinine level increases, the length of gestation shortens, newborn birth weight decreases, postpartum adaptation worsens, and the length of maternal hospitalization increases. To perform the research, we retrospectively collected data from pregnant women with a PE diagnosis who gave birth at the Department of Obstetrics and Gynaecology of the First Faculty of Medicine of Charles University and of...

Common Security and Defence Policy: Civilian Crisis Management of the European Union - A Geopolitical Perspective
Smejkalová, Tereza ; Hnízdo, Bořivoj (advisor) ; Kříž, Zdeněk (referee) ; Cabadová-Waisová, Šárka (referee)
The aim of my work is to apply the political-geographical or geopolitical optics to a specific foreign security activities of the EU, i.e. to put political aims and activities of political-geographical framework. In geopolitical terms, it is necessary to assess the potential and the current deployment of civilian missions. For this purpose, in accordance with the hypothesis of my work, that the civilian aspects of crisis management CSDP are based mainly on the willingness and desire of Member States in a given area or country involved should be analyzed for the three major priorities of Member States (UK, Germany and France) in civilian areas (see National Security Strategy). The work compares the current activities of EU civil security-CSDP and geopolitical intentions of the three great European powers, Germany, France and Great Britain. Civilian CSDP should concentrate in geographic areas that are of key importance to most member states and especially for three large powers. The question is whether the major European powers reflect their priorities in EU policy in its entirety or whether there are other factors that prevent them from doing so. Such factors include decisions based on consensus and the growing power of the European Commission, which defends its interests very hard in the CSDP. Large Member...

The use of high temporal resolution satellite data for monitoring of water quality
Šmejkalová, Tereza ; Štych, Přemysl (advisor) ; Slačíková, Jana (referee)
The use of high temporal resolution satellite data for monitoring of water quality Abstract Present study compares possibilities of sea water quality monitoring using high temporal resolution satellite data. The theoretical part describes basic principles of remote sensing, the spectral characteristics of water and their change caused by substances present in the water. The analytical modeling methods of chlorophyll-a concentration retrieval from MERIS data are described. In the study three processors are used, standard MERIS processor Case 2 Regional, FUB/Wew Water processor and FLH/MCI processor. In total 10 satellite images are processed, five for each of the two studied areas, the Golfe du Lion in France and Skagerrak and Kattegat straights in Northern Europe. As there is only limited dataset of in situ measurements available to validate the results, it is impossible to decide which of the processors is the most suitable one. It is however clear that none of the globally applicable algorithms can be as accurate as algorithms developed for the exact location and atmospheric actual conditions.
