Černý, Jakub ; Aslan, Emil (advisor) ; Karásek, Tomáš (referee) ; Gebhart, Jiří (referee)
UNIVERZITA KARLOVA V PRAZE FAKULTA SOCIÁLNÍCH VĚD Jakub Černý GEOPOLITIKA REGIONU KASPICKÉHO MOŘE V KONTEXTU PRÁVNÍHO REŽIMU VYUŽÍVÁNÍ JEHO ZDROJŮ Rigorózní práce Praha 2011 Rigorózní práce 3 Autor práce: Mgr. et. Mgr. Jakub Černý Konzultant: PhDr. Emil. Souleimanov Ph.D. Rigorózní práce 4 Resumé: Práce se zabývá otázkou určení právního statusu a rozdělení Kaspického moře v širších geopolitických souvislostech. Problematika je nahlížena z pohledu mezinárodního práva v kontextu mezinárodních vztahů mezi relevantními aktéry, na úrovni lokální, regionální a globální. Teoretická analýza aplikace odlišných právních výkladů je zasazena do celkového kontextu vztahů relevantních regionálních a globálních aktérů s cílem dokázat, jak politika a zájmy jednotlivých států determinují jejich výklad mezinárodního práva. Ukáže se, že spíše než pobřežní státy, kterých se určení právního režimu - pravidel rozdělění a využívání prostoru a jeho zdrojů - fakticky týká, ovlivňují proces aktivity globálních hráčů sledujících region geostrategickou perspektivou (nejen) v souvislosti s kontrolou jeho významných energetických zdrojů. Summary: Subject of the thesis is the definition of the Caspian Sea legal status in wider geopolitical perspective. The Caspian case is analyzed from the perspective of the international law in the...

Simulator of IEC 60870 communication
Calábek, Tomáš ; Bohačík, Antonín
The power industry’s evolution hinges on efficient and reliable transmission, distribution, and control of electricity, increasingly facilitated by remote monitoring and control systems. Among these, SCADA technologies stand out, enabling centralized supervision and management of energy infrastructure. Central to these systems are communication protocols such as protocols from IEC 60870 standard, facilitating data exchange within power networks. This paper introduces a communication simulator based on IEC 60870-5-101/103/104 protocols. Our simulator for IEC 60870 is capable of simulating all three mentioned protocols on the client-server principle. It can simulate both balanced and unbalanced transmissions, adjust transmitted data, set quality bits, and much more. Our simulator was tested in a virtual environment.

Price Elasticity of Electricity Revisited: A Meta-Analysis
Šikl, Vojtěch ; Havránková, Zuzana (advisor) ; Petit, Mathieu (referee)
Despite a plethora of empirical research on electricity demand, results regard- ing estimated price elasticities persist to be inconclusive. Our meta-analysis synthesizes 4521 estimates from 413 studies to explore the presence of publi- cation and endogeneity bias. We code for over 100 variables to quantify the response of electricity consumers to price shifts. The price elasticity of electric- ity is inelastic and the short-run elasticity sample average of -0.231 is double (in magnitude) the short-run elasticity corrected for publication bias, which is -0.116. The long-run elasticity adjusted for publication bias is -0.303. We conclude that experimental studies, while also su ering from publication bias, report unbiased elasticities of -0.07. Our thesis also confirms a significant occur- rence of p-hacking across multiple specifications. By employing Bayesian model averaging, we explore the heterogeneity among reported elasticities, finding that factors such as decreasing tari s, demographics and fuel usage controls, daylight hours and number of citations critically influence the variability in findings. The average and marginal price of electricity and time of use tari s play a negligible role in explaining the di erences in estimated elasticities. JEL Classification D01, Q40, Q49, C11 Keywords...

Securing an International Role Through Energy: The Case of UAE
Kováčová, Marína ; Kalhousová, Irena (advisor) ; Buriánek, Petr (referee)
The aim of this bachelor thesis is to elucidate the energy policy of the United Arab Emirates (UAE) and to explain its motivation through the neorealist theory of international relations. The UAE possesses one of the largest global hydrocarbon capitals. Recent years have shown that despite its oil and gas wealth, the country is intensifying its investments in renewable transition and enhancing sustainable energy policies. This thesis attributes the motivation for such change in direction to the interest in anchoring economic and political security on the international stage. The thesis is systematically divided into two main parts, the first of which outlines the theoretical grounding of the topic in the context of international relations, while the second offers empirical examples of specific policies implemented by the country. I concurrently link the identified policies with neorealism and highlight their importance in the country's foreign policy. Keywords United Aram Emirates, Energy, Renewable Energy, National Interest, COP28, Neorealism, Political pragmatism

Glycolysis and substrate-level phosphorylation in parasitic protists
Šírová, Lucie ; Hrdý, Ivan (advisor) ; Malych, Ronald (referee)
Glycolysis is an important metabolic pathway that conserves energy within cells. During the breakdown of glucose, molecules of ATP are synthesized in processes of substrate-level phosphorylation. The classical pathway follows the Embden-Meyerhof scheme, but there are remarkable deviations in many organisms. This is the case of parasitic protists. Their glycolytic pathway differs in some of the enzymes used. This thesis focuses on glycolysis and ATP-synthesizing reactions in selected parasitic protozoa. Specifically focuses on Trichomonas vaginalis, Giardia intestinalis, Entamoeba histolytica and Trypanosoma brucei spp. In individual subchapters, their glycolytic pathways and related enzymes are described, from the initial substrate, glucose, to the final products. Key words Glycolysis, substrate-level phosphorylation, parasitic protists, ATP, pyrophosphate, energy

Design of a PV plant for a family house
Kalousek, Stanislav ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
This bachelor thesis deals with the design of a photovoltaic power plant in combination with a heat pump for a family house. The theoretical part of the thesis includes a detailed analysis and analysis of currently used photovoltaic and heat pump technologies with the use of possible government subsidy programs. Furthermore, the practical part describes the layout of the family house for which both systems are proposed. Based on the knowledge gained, the design of the heat pump and photovoltaic power plant is proposed, including a system for the storage of electrical energy or the sale of surplus to the distribution grid. In addition, a simulation of the operation of the PV power plant is performed in the professional design environment PV*Sol Premium, including a 3D model, module shading, economic and energy analysis of the PV power plant design. Finally, an evaluation of the combination of a PV plant with a heat pump and a comparison with a commercial design from a professional PV and HP installation company is made.

Evaluation of iron intake in a selected group of women
KRŮČKOVÁ, Dominika
This thesis focuses on the assessment of iron intake in women. Women, especially those of childbearing age, are an at risk group for iron deficiency anaemia. This is because of the higher need for this trace element due to its loss during menstruation, in pregnant and lactating women the need for iron increases due to fetal nutrition and increased red blood cell production to ensure adequate oxygen transport to both mother and fetus. Iron intake was monitored in two groups of women, with the first group comprising women younger than 50 years of age, while the second group included women older than 50 years. Both groups consisted of six female respondents. Iron intake was assessed through four weekly dietary intakes. Dietary consumption was recorded for one year. One weekly diet was recorded by the respondent in each season. The diets were analysed through publicly available databases. The recommended standard for nutrient intake was based on the recommendations of DACH (2019). The aim of this study is to analyze the intake of iron, energy and essential nutrients and to compare the resulting values both within the two groups of respondents and with the official recommendation for the intake of each nutrient. According to the results, only one respondent from the age group over 50 years does not meet the recommended standard of 10 mg iron/day. In the group of women under 50 years of age, only 1 respondent meets the recommended standard of 15 mg iron/day. However, the iron intake of most of the respondents can be assessed as satisfactory. Furthermore, there was a difference in iron intake between the two groups of women, with women under 50 years receiving statistically more iron than women over 50 years. The effect of season on iron and essential nutrient intake was not demonstrated. A statistically significant difference was observed only in the energy intake of the group of women over 50 years of age, namely between the summer and autumn seasons, with women in this group taking in statistically more energy in the autumn season compared to the summer season. Furthermore, a positive moderate correlation was found between protein and iron intake. A varied and balanced diet that includes iron rich foods such as red meat, poultry, fish and legumes is essential for adequate iron intake. Iron absorption can be aided by simultaneous consumption of foods containing vitamin C.

Fazlić, Aida ; Kuchynka,, Michaela (referee) ; Pořízka, Pavel (advisor)
Tato diplomová práce se zaměřuje na detekci a analýzu těžkých kovů, zejména olova (Pb), v tvrdých tkáních pomocí hydroxyapatitových standardů a spektroskopie laserem buzeného plazmatu (LIBS). Studie využívala různé vlnové délky laseru 1064 nm, 532 nm a 266 nm, stejně jako různé konfigurace laseru, včetně jednopulzní (SP, z angl. single-pulse) LIBS a dvojpulzní (DP, z angl. double-pulse) LIBS v ortogonálním a kolineárním uspořádání. Byla provedena optimalizace parametrů laseru, jako jsou vlnová délka, defokus, doba zpoždění, mezipulzní doba zpoždění a energie. Poměr signál-ke-šumu (SBR), limit detekce a rozlišení odpovídající průměru ablačního kráteru sloužily jako základní parametry pro určení optimální kombinace parametrů. Výsledky této studie poskytují důležité poznatky o optimálních parametrech LIBS pro detekci a analýzu těžkých kovů v tvrdých tkáních, což může mít potenciálně významné dopady pro lékařský výzkum.
