Just Intonation and the Revitalization of Neoclassicism: Three Works for Baroque Instruments

Figg, Graham Elliot 05 1900 (has links)
For a composer of today, the relationship between new music and music from many centuries past remains problematic. In order to create something new, it is necessary to go beyond previous techniques of composition in some way. At the same time, new music that has no connection with music of the past runs the risk of irrelevance. Just tuning offers one possibility for reconciling this problem. By effectively warping music of the past through the lens of altered tuning and contemporary composition techniques, music of the past may be understood in previously unknown ways. Part I, the critical essay, presents historical background and analysis of a cycle of three works in altered/just tuning. Part II presents scores of the works.

Předlužení spojené se spotřebitelským financováním - možná řešení a návrh opatření / Overindebtedness connected to consumer finance - possible solutions and suggested precaution

Zelený, Martin January 2017 (has links)
This thesis is mapping current situation in the area of consumer lending, shows main reasons and impacts of overindebtedness and also its connetion to consumer lending. The target is to suggest appropriate regulation to lower the rate of overindebtedness, that exists in this area due to the absence of regulation in the area of consumer lending in Czech republic. Suggested regulation insures higher consumer protection and compact rules for all the partcipants on the consumer lending market. It also collects complex information about clients and their debt ratio. It has advantages for all participants.

Reakce iontů s molekulami H2 a rekombinace iontů H+3 s elektrony při kryogenních teplotách / Reactions of Hydrogen Molecules with Ions and Recombination of H+3 Ions with Electrons at Cryogenic Temperatures

Hejduk, Michal January 2013 (has links)
We studied how distribution of nuclear-spin states of H+ 3 ions or H2 molecules influence rate coefficients of H+ 3 -electron recombination or reactions of H2 with N+ or H+ , with regard to kinetic and internal temperatures of the reactants. Experiments were carried out in plasma environment or in an ensemble of ions in an ion trap. Main diagnostic methods were the Langmuir probe diagnos- tics, laser absorption- and mass spectroscopy. The distribution of nuclear spin states (para and ortho) was varied using a specially constructed para-hydrogen generator. We performed pioneer measurements of the rate coefficients for the nuclear-spin-state-selective binary and ternary H+ 3 -electron recombination in thermalised plasma. We performed studies of N+ + para/ortho-H2 reaction with high accuracy and interpreted the results as dependent on fine structure states of N+ ions. We measured a temperature dependence of the rate coeffi- cients for radiative and ternary channels of H+ + para/ortho-H2 association. 1

Laboratorní výzkum reakcí iontů s molekulárním i atomárním vodíkem při teplotách relevantních pro astrochemii / Laboratory studies of ion-molecule reactions with molecular and atomic hydrogen at temperatures relevant to astrochemistry

Mulin, Dmytro January 2015 (has links)
The results of the laboratory study of reaction rate coefficients of several ion- molecule reactions with atomic and molecular hydrogen and molecular deuterium at low temperatures are presented in the thesis. The reaction rate coefficients of the N+ and H+ reaction with H2 were measured with respect to the nuclear spin configuration and rotational excitation of H2. The reactions of anions were a subject of the isotope exchange and isotope effect study. The measurements of the rate coefficients of H2O and D2O formation in the reaction of O- with H2 and D2, isotope exchange reactions OH- + D2 and OD- + H2, and associative detachment and charge transfer channels of D- + H interaction were performed. Experiments were carried out using an AB-22PT instrument with an ion trap. It has producing, guiding, trapping, and detecting systems for ions and a separate source of atomic H. The cooling system allowed to measure the temperature dependencies of the reaction rate coefficients at temperatures relevant to astrochemistry (10 K - 300 K)

Formování vody reakcemi aniontů i kationtů s molekulárním vodíkem při nízkých teplotách / Water formation in reactions of anions and/or cations with molecular hydrogen at low temperature

Tran, Thuy Dung January 2020 (has links)
In the present work, the results of the experimental study of reactions of ions with molecular hydrogen in the temperature range 15 - 300 K using a 22-pole ion trap apparatus are presented. The reaction of OD- with para-enriched hydrogen was studied using a combination of the 22-pole ion trap apparatus with a para-hydrogen generator. Also reactions of O- with H2, D2, and HD were studied. These reactions have a channel of water production and a channel of hydrogen or deuterium transfer. Another field of study was a sequence of reactions of oxygen hydride cations with H2 and D2 which leads to the production of H3O+ or its isotopic variant, specifically reactions OH+ with H2, H2O+ with H2, D2O+ with H2, and D2O+ with D2. This reaction chain can be followed by the electron recombination of H3O+ or its isotopologue, which has a channel of water production.

Soukromé archivy - stopy minulosti v naší přítomnosti / Private Archives - The Traces of Past in Our Present

Zíková, Markéta January 2017 (has links)
The main topic of Master thesis with the title Private Archives - The Traces of Past in Our Present, is creation of private archives and how reading and work of French philosopher Gilles Deleuze support understanding of those archives and establishment of intimate history of human being. Private archives are represented by any object, collections of objects or by anything else what reminds to owner or author of archives his past and who is returning back to the past through this object. Private archives are present in life of human being and we are coming back to the archives whenever we consider it important and whenever we want. Private archives are the part of life of all of us and that is why I consider crucial to understand their functioning, their role in our life and to know how to use them. The private archives, unlike our memories, which can be mixed one into each other, represent concrete tool referring to our past. The master thesis includes the description of practical part which is represented by creation of private archive, the functioning and the characteristics are also described. Three philosophers who influenced Gilles Deleuze have their place in this master thesis as well. I am referring to Michel Foucault, Henri Bergson and Marcel Proust.

Světové dědictví UNESCO jakožto místa paměti. Komparativní studie kolektivní paměti a veřejného využívání historie / Unesco World Heritage Sites: Ways of Presenting & and Interpreting the Pas. As seen in: Kutná Hora, Hiroshima Villa Romana del Casale

Kovářová, Linda January 2017 (has links)
This thesis deals with a specific group of historical sites called World Heritage, which are registered on the UNESCO World Heritage List. It characterizes the basic elements of the UNESCO World Heritage idea as a cultural and social process, which engages in acts of remembering that work to create ways to understand, present and interpret the past within the present social frameworks. The thesis brings to the attention a range of viewpoints about the nature of heritage in general and the UNESCO World Heritage in specific that have emerged in the relatively new area of academic interdisciplinary heritage studies. For the purposes of exploring different aspects of the World Heritage phenomenon, following themes of heritage discourse have been developed: remembering and making public use of the past, the UNESCO approach and the ways of presenting and interpreting the past. In order to give a sense of what World Heritage looks like on the ground this thesis details some aspects of three different World Heritage sites. To study such matters in the physical world a strategy of undertaking case studies of three specific UNESCO sites and employing the methods of direct observation and a fieldwork were chosen. Closer examinations of the Czech medieval town of Kutná Hora, the Hiroshima Peace Memorial Park...

Holokaust v politickém diskurzu postkomunistických států: projevy prezidentů České republiky a Polska / Holocaust in Political Discourse of Post-Communist Countries: Speeches of the Presidents of the Czech Republic and Poland

Ďurková, Michaela January 2018 (has links)
This thesis deals with the issue of memory and remembering in the post-communist area. In particular, it examines the form, extent and success of the Holocaust reflection and coping with the past on the example of the speeches of Czech and Polish presidents from 1993 (Václav Havel), or 1995 (Aleksander Kwaśniewski) until the access to the European Union in 2004. Author of the thesis assumes that the fall of Communism and the restoration of the democratic establishment represented a significant impetus for the countries in question to deal with their past. At the same time, they try to prove that the Holocaust memory politics of key political representatives of the Czech Republic and Poland has been one of the important factors in the creation of their post-communist democratic identity - and not only with respect to an unofficial demand of the unifying Europe to cope with the heritage of the past. Through the analysis of selected presidential speeches, the thesis identifies and evaluates the image of Holocaust created by the Czech and Polish presidents on the one hand and the weaknesses in the Holocaust memory politics of both actors on the other. After theoretical and conceptual introduction (chapter one), the experience with the Holocaust in Poland and the Protectorate of Bohemia and Moravia, and...

Sezónní variabilita aktivity a promořenosti patogenem v populacích raka pruhovaného / Seasonal variation of activity and pathogen prevalence in populations of the spiny-cheek crayfish

Matasová, Klára January 2011 (has links)
The most widespread of invasive crayfish in the Czech Republic is the spiny-cheek crayfish (Orconectes limosus). It is a major disease carrier of crayfish plague, caused by the pathogen Aphanomyces astaci. The infection is lethal to European native species of crayfish. Transmission of this disease is usually associated with the spread of crayfish, which is dependent on their movement. The main aim of this work was to evaluate the differences in crayfish migratory activity in the Pšovka brook among seasons, and assess the factors that may affect it, by the use of radiotelemetry and trapping. We tested the hypothesis that crayfish use brook in the period from spring to autumn and then return back into a pond to overwinter. Furthermore, we evaluated how far from the pond crayfish migrate, and whether there is any relationship between migration and the season or water temperature. The results demonstrate that the activity varies among seasons (being strongly affected by breeding season) but in most studied periods did not significantly depend on water temperature. According to our monitoring, the spiny-cheek crayfish does not spread substantially to upstream parts of the Pšovka. Seasonal migration between the pond and the brook was monitored using two-way flow-through traps installed at the mouth of...
