Thermal analysis of interaction of epidermal lipids V
Kaloušová, Petra ; Musilová, Marie (advisor) ; Doležal, Pavel (referee)
Thermal analysis of interaction of epidermal lipids V Petra Kaloušová, degree work , June 2009 Abstract Natural function of human skin is to protect the body from adverse influences of the surrounding. In 1950's and 70's it was discovered, that the skin barrier is situated in stratum corneum and is determined by lipids in intercellular space of that layer. Transdermal application of medicaments has many advantages compared to peroral one. On the other hand stratum corneum is a certain barrier for penetration of the medicaments. Thus we have focused on this lipid layer and its interaction with water. We have used samples prepared in vitro consisting of cholesterol, pseudoceramid and modulators of transdermal penetration. We have tried to hydrate the samples and tracked their characteristics and interactions by differential scanning calorimetry. At the same time we have evaluated the individual groups of drugs and proper experimental conditions for that particular measurement.

The exercise of the state's rights and duties in the airspace in the light of public international law
Kobera, Václav ; Ondřej, Jan (advisor) ; Hofmannová, Mahulena (referee)
108 THE EXERCISE OF THE STATE'S RIGHTS AND DUTIES IN THE AIRSPACE IN THE LIGHT OF PUBLIC INTERNATIONAL LAW The space above the Earth was the lawyer's examination subject matter already in ancient times. The air which we breathe, as well as the water from the sea, was considered to be a thing common to all (res communis omnium). However, as far as the movement and life in the air were concerned (here we can use the term "airspace"), a different rule was used. This rule said "he who owns the land, owns it up to heaven" (cuius es solum, eius est usque ad coelum). This conception of the airspace still had not much in common with today's conception based on its practical use. It is obvious that society then could not have assumed reasonably (because of the level of its technical development) that mankind was going to be able to use the airspace. The origins of proper use of the airspace we can only date to when the Montgolfier brothers constructed and launched the first hot air balloon (1783 in Paris). Initially such activities were considered to be rather curiosities but they gained respect very quickly especially when used during armed conflicts in the 19th century performing espionage and bombing tasks. At the beginning of the 20th century the Wright brothers successfully tested the first heavier-than-air...

Příklady odhadu stavu a parametrů pro lineární model s rovnoměrně rozloženými inovacemi
Pavelková, Lenka
In this contribution, state-space model with uniformly distributed innovations is introduced and the Bayesian state estimation proposed. The off-line evaluation of the maximum a posteriori probability (MAP) estimate of unknowns in the linear state-space model with uniform innovations reduces to linear programming (LP). The solution provides either estimates of the noise boundary and parameters or of the noise boundary and states. The on-line estimation is obtained by applying LP on the sliding window, i.e., by considering only the fixed amount, say partial, of the newest last data and states items. By swapping between state and parameter estimations, joint parameter and state estimation is obtained. The use of Taylor expansion for approximation of products of unknowns solves also the joint parameter and state estimation. Simulation studies help to get an insight on the potential and restrictions of these heuristic method. This contribution shares the experimentally gained experience with both these solutions of the joint state and parameter estimation.

Some aspects of the discontinuous Galerkin method for the solution of convection-diffusion problems
Hájek, Jaroslav ; Najzar, Karel (referee) ; Feistauer, Miloslav (advisor)
This work is concerned with the numerical solution of initial-boundary value problems for convection-diffusion partial differential equations. Three methods are studied and compared for this purpose: the combined finite element - finite volume (FE-FV) method, the discontinuous Galerkin finite element (DGFE) method of lines, and the spacetime discontinuous Galerkin method. The combined FE-FV method uses piecewise linear conforming finite elements for the discretization of the diffusion terms and piecewise constant FV approximation of the convective terms. The relation between the FE and FV approximations is determined by the so-called lumping operator. In the DGFE method of lines, the space semidiscretization is carried out by piecewise polynomial functions constructed over a triangular mesh, in general discontinuous on interfaces between neighbouring elements. In the space-time DGFE method, the approximate solution is piecewise polynomial in space as well as in time. We discuss both theoretical and practical aspects of the methods, and present numerical results for each of them. For the DGFE method of lines we derive an a posteriori error estimate.

Inflation and the Steeplechase Between Economic Activity Variables
Baxa, Jaromír ; Plašil, M. ; Vašíček, B.
A sharp increase in unemployment accompanied by a relatively muted response of inflation during the Great Recession added further doubts to the validity of the Phillips curve and the existence of a systemic relationship between economic activity and inflation. This paper aims to show to what extent the uncertainty about the choice of proper forcing variable contributes to the ambiguity of the evidence on the Phillips curve in the United States and other G7 countries. We use dynamic model averaging (Raftery et al., 2010), which marries the flexibility of the time-varying parameter framework with the possibility of model switching in each period. Our results show that inflation seems to respond to different measures of economic activity across time and space to a varying extent and no measure of economic activity clearly dominates in all countries or over the whole sample.

Vocabulary of Czech sci-fi short stories
Mráčková, Michaela ; Bozděchová, Ivana (advisor) ; Lehečková, Eva (referee)
The presented Bachelor thesis, Vocabulary of Czech sci-fi short stories, is focused on describing lexicological and morphological means used in a sample of words used in a Czech sci-fi magazine XB-1. The analysed words have been categorized by their terminological, neological, proper noun and slang nature. This served as the basis of structure of this thesis. In the semantic part, this thesis deals with real objects typical for the described literary genre (space travel devices, technical inventions, unusual science fields, etc.) and thus confronts the real and fictional worlds. The thesis summarizes the word-forming means where authors need to create new words for new objects and the thesis describes some of their common trends. Last but not least, this thesis assessed the function of these word-forming means in such a specific literary genre. The analysed expressions (more than 600 entries) are included as a table attachment with notes. Powered by TCPDF (www.tcpdf.org)

Party System Formation in Russia - a tendency to monocentrism
Gutsul, Yulia ; Prorok, Vladimír (advisor) ; Dvořáková, Vladimíra (referee) ; Iličeva, Ludmila (referee)
Research of process of forming of party system of Russia at the present stage acquires special relevance that is caused by changes of a political regime. Change of nature of a political regime, sharpening of personalistic, unicentric lines has caused search of a new format of party system which would minimize possibility of instability of a political regime and became the effective mechanism of maintenance of the status quo. Main goal of dissertation research is studying of forming of a tendency to a monotsentrichnost in development of party system of the modern Russian Federation. Hypotheses which have proved to be true have been formulated: forming of unicentric party system when using strategy of a party creation of the power and its positioning in political space I became reaction of political elite of Russia to a situation of democratic transit and manifestation of its pragmatical interests.

SUGGESTIONS FOR DEVELOPMENT OF IMPROVISATION IN ORGAN MUSIC
Steyer, Jan ; Popelka, Josef (advisor) ; Hora, Jan (referee)
Bachelor work Suggestions for development of improvisation in organ music is, as its name shows, a complex of suggestions which tries to inspire the reader to improve his organ improvisation work. In no way it should be apprehended as a full textbook of organ improvisation. On the contrary the reader should be at least familiar with the improvisation basics. The work consists of four topics which are connected. The first is focused on improvisation of melodic line, second works with harmony, followed by issue of counterpoint and the work finishes dealing with improvisation ordination with regards to formal structure. Each of these topics includes proper themes associated with practical music examples and tasks appointed to the reader. The work emphasizes own esthetic feeling of the player, communication role of music and favours contemporary music ways of expression.
