Estimating the Relationship between Food, Fuel and Biofuel Prices
Novotný, Matěj ; Janda, Karel (advisor) ; Khymych, Olha (referee)
Although biofuels have drawn the attention of researchers since its boom, which took place 20 years ago, doubts about benefits which their usage brings in the academic debate. This thesis joins the debate that discusses the impact of biofuels on food prices. The prices of 38 commodities and assets that are related to the biofuels are examined under Minimum Spanning Tree and Hierarchical Tree methods over the years between 2003-2019. The time span is divided into 4 periods, that responds to the development of world food prices. The results show that the relationship between biofuels and their feedstock depends on the overall level of food prices. In the case of higher food prices, the link between feedstock and biofuel is stronger and therefore the price transmission is more likely to happen. With lower food prices, this link is significantly weaker. Furthermore, the development of world food prices does not follow the trend of increasing biofuels production as food prices have become stable in recent periods. Therefore, this thesis does not support the claim that biofuels cause higher prices of food. Keywords biofuels, ethanol, biodiesel, transportation, food price transmission, Minimum Spanning Tree, Hierarchical Tree 1

The Impiety in Classical Athens
Novotný, Matěj ; Souček, Jan (advisor) ; Bednaříková, Jarmila (referee) ; Kysučan, Lubor (referee)
Matěj Novotný - Impiety in Classical Athens Abstract The thesis discusses the definition and prosecution of impiety in democratic Athens during the Classical period, i.e. in 5th-4th centuries BCE. The question of "impiety" in the narrower sense, i.e. of what was denoted by the Greek word ἀσέβεια (literally, "the absence/negation of respect"), is set into larger context of other crimes of religious character, covered by special laws: "sacrilege" (ἱεροσυλία), digging out sacred olive-trees, offences against festivals and other delicts which were not subsumed under any more general term in the laws, pragmatically formulated as they were. The dissertation builds on the work of the researchers who show considerable scepticism towards the reliability of later sources, for example Plutarch or Diogenes Laertius - this is connected with doubts concerning processes against philosophers before Socrates. At the same time, the thesis follows the scholars who doubt the authenticity of the documents inserted in the speeches of the Attic Orators. For these reasons, a considerable part of the thesis is devoted to the rebuttal of late reports and inserted documents. A particular attention is given to the Decree of Diopeithes, which is mentioned in Plutarch's Life of Pericles and is usually interpreted as criminalising...

Study of contamination of river sediments with platinum metals
Novotný, Matěj ; Řezáčová, Veronika (referee) ; Komendová, Renata (advisor)
This work deals with the characteristics of platinum metals and problems related to their toxicity and mobility in the environment, especially in the aquatic environment. These metals are released into the environment due to the use of automotive catalysts. Their function is based on the catalytic properties of platinum metals. Because of the high temperatures, these metals can be oxidized in the catalyst and subsequently emitted together with the combustion products into the surrounding atmosphere. The aim of the thesis is to measure real samples of river sediments of the river Svratka on the territory of the city of Brno and to find the possibility of contamination of the aquatic environment with these metals.

Abuse of the Sources of Ionizing Radiation
NOVOTNÝ, Matěj
The goal of submitted bachelor thesis is to summarize the problem of a possible misuse of ionizing radiaton sources, and especially to evaluate the Region of South Bohemia´s citizens´ knowledge within the area of ionizing radiation sources misuse. To fulfill the given goals it is necessary to study expert literature as well as the formulation of hypotheses which are further tested and examined in action. Individual questions are subsequently processed and evaluated. Determined hypotheses are tested on the basis of parametirized and non-parametirized testing. The bachelor thesis should introduce the reader to the basic terms within the area of ionozong radiation problem and its positive and negative use. Mainly it includes terms such as ionizing radiation and its biological effects, protection from ionizing radiation, and its sources. Attention is also paid to the use of ionizing radiation in radiotherapeutic and radiologic departments, in nuclear medicine or industry. In the following theoretical part the thesis focuses on the misuse of ionizing radiation sources as well as on radiologic terrorism which occurs as a huge threat for the humankind, having been already fulfilled several times. Nowadays, the greatest risk has been the use of a radiological weapon, so-called ´dirty bomb´ which may be misused by radical terrorist groups or may be available on the ´black market´. The practical part focuses on the research connected to the Region of South Bohemia citizens´ knowledge within the area of ionizing radiation and its misuse. This research is implemented via a questionnare survey. The questionnare contains 13 multiple-choice questions. Each question contains 4 multiple-choice answers (in the form of a), b), c), d)) out of which only one is correct. Two cities and five municipalities in the region of South Bohemia were randomly selected. There were 200 questionnaires in total out of which the first half was meant for cities and the other one was meant for municipalities. Questionning was carried out among respondents within age categories of 18-70 and questionnaire survey was carried out during the period of May to June 2016. In general the evaluated results of the questionnaire survey have showed that most knowledge regarding the given topic of the bachelor thesis was average, rather below the average. To be more specific, a higher success rate was noticed in the interviewed city residents rather than in municipality citizens. The difference in response unsuccess rate may be found in questions no. 7, no. 10, and no. 11 when interviewed municipality citizens had worse results in 68% average in comparison to city residents. On the contrary, municipality citizens proved better knowledge in question no. 9. Questions number 1, also number 2 and number 3 got the highest response success rate in all intervewed city residents and municipality citizens, where approximately more than 50% of the interviewed replied correctly. The main benefit of the bachelor thesis is the gained image of the Region of South Bohemia cities and municipalities´ citizens´ knowledge of the possible misuse of ionizing radiation sources. The theoretical part may serve as a study text for students of Population Protection study subject or connected study subjects.

Analysis in Banach spaces
Novotný, Matěj ; Hájek, Petr (advisor) ; Kurka, Ondřej (referee)
Univerzita Karlova Abstract of the diploma thesis Analysis in Banach spaces Matěj Novotný, Praha 2013 In the thesis, connection between two certain types of equivalence on Ba- nach spaces is studied: Between Lipschitz and linear one. In general, linear equivalence of two Banach spaces implies their Lipschitz equivalence, but the converse need not be true, which is shown by some nonseparable examples. There are summarized several examples to this question in the thesis, both positive and negative ones. Moreover, it is shown that James' quasi-reflexive space and its dual space have unique Lipschitz structure. To prove this, theory of linearization of Lipschitz mappings and at the same time linear structure of the two mentioned spaces is used. 1

Composition operators on function spaces
Novotný, Matěj ; Spurný, Jiří (advisor) ; Kalenda, Ondřej (referee)
Univerzita Karlova Abstract of the bachelor thesis Composition operators on function spaces Matěj Novotný, Praha 2011 In the thesis we define what is an composition operator on the space of continuous or measurable functions of one complex variable so that we may proceed to study its properties depending on properties of the mapping the operator is induced by. We search for conditions under which the operator is continuous, compact and an isomorphism. We roughly estimate the spectrum of an operator defined on a space of continuous functions. 1

The Andokides' speech On the mysteries. Translation, commentary and introductory study
Novotný, Matěj ; Marek, Václav (referee) ; Souček, Jan (advisor)
In the end of the 5th century B.C., the Andokides' speech On the mysteries represents an interesting source of information. It focuses on the processes with impious criminals who mutilated herms and profaned Eleusinian mysteries in 415 B.C., and the revision of Athenian laws in 403 B.C. This thesis attempts to present this speech in historical context, to evaluate critically its credibility, and to point out general problems concerning the use of the corpus of the Attic orators as a source of information regarding political and legal history. Thus the centre of the thesis lies in the commentary attached to a completely new Czech translation of Andokides' speech.
