This thesis entitled "Effect of gloeosporium rot as gaseous constituents of apple varieties" deals with microorganisms in terms of storage and processing. Characterized mainly epiphyte microflora occurring on apples, mainly sponge Gloeosporium spp. Specifies how does this affect rot on the gaseous components in the fruit, how it affects breathing and the formation of ethylene and what risks may cause the processing. Features mold and products of their metabolism, concentrations and health risks. The conclusion of this paper describes the experimental determination of the invading microorganisms fruit during storage.

In a field of environmental protection there is a very important question about the options to determine impact of different pollution sources on air quality in areas more or less distant from those sources. For those predictions we can use physical or computer modelling. In this paper a computer model (Lagrangian Dispersion Model, or LDM) of air pollution propagation is developed and described. The LDM was created in order to work within the CLMM - Charles University Large-Eddy Microscale Model. In this paper we discuss theory of those models as well as technical solutions used to develop the LDM. The model is validated and subsequently applied on several cases with different degree of geometry complexity. Powered by TCPDF (www.tcpdf.org)

Title: Study of C-C coupling of dienes catalyzed by ruthenium (II) complexes. Author: Bc. Eva Hanikýřová Department: Department of Organic Chemistry Supervisor: Mgr. Jana Roithová, Ph.D. Abstract Transition metal catalyzed cycloadditions have contributed extensively to organic synthesis. The use of ruthenium complexes in those reactions gain importance due to their demonstrated ability in the catalytic carbon-carbon bond formations via ruthenacycle intermediates. In our studies, we have concentrated on the interaction between ruthenium (II) and alkenes using mass spectrometry with electrospray ionization. This technique allows to investigate ruthenium complexes in the ionized states, and allows to investigate these structures by using MS/MS analyse. Our experimental research was complemented by quantum chemical calculations using Density functional theory. The research leads to a more detailed understanding to Ruthenium complexes with unsaturated hydrocarbons reaction mechanism. Key words Gas-phase chemistry, Reaction mechanisms, Electrospray Ionization, Catalyst, [CpRu(CH3CN)3]PF6, Mass Spectrometry

The doctoral thesis deals with the structure and properties of the polycrystalline silicon layers deposited on the silicon wafers backside. The wafers are further used for production of semiconductor devices. This work is focused on detailed description of the layers structure and study of the gettering properties and residual stress of the layers. The main goal of this work is to develop two novel technologies. The first one leads to improvement of the temperature stability of the gettering properties of the layers, and the second one solves the deposition of the layers with pre-determined residual stress. This doctoral thesis was created with the support of the company ON Semiconductor Czech Republic, Rožnov pod Radhoštěm.

Within the presented thesis there were collected data of effluents of 14C chemical forms from ventilation stacks of the Unit 1, the Unit 2 and the Auxiliary Building of the Temelin NPP for the period from 2001 to 2006. These data are compared to power of both reactors and concentration of ammonium ions in coolant of the primary circuit of the Unit 1 and Unit 2.

This work deals with monitoring of the radiocarbon in the gaseous effluents from the Temelín nuclear power plant and its distribution in the environment. The reader should gain a comprehensive image about level of radiocarbon monitoring in ventilation systems in the Temelín nuclear power plant and in the surrounding environment. The work is divided into several parts. Some basic information of physics, chemistry and radiobiology relating to radiocarbon are given in the first part. The origin of radiocarbon in VVER reactor, its pathway to gaseous releases and then to carbon cycle in the environment are described there too. This introductory part continues with description of monitoring methods used in ventilation systems of the Temelín nuclear power plant and in the surrounding environment. Summary of Czech Republic legislation related to radiation protection is stated. The aim of the work and hypothesis are set in the second part. In the third part there are methods used to fulfil the aim of the work. The results in the form of tables and graphs are in the fourth part. In the following part there is a discussion of summarized data and results. Developed findings are summarized in the last part of this work.

This diploma thesis deals with electrical conductivity of a graphene sample, preparation of a graphene field-effect transistor and his irradiation by electron beam. In the theoretical part of the thesis, we describe electronic properties of graphene, preparation of graphene by CVD and its transfer to Si substrate with SiO_2 layer. Experimental part of this thesis is focused on the preparation of a graphene field-effect transistor for use in UHV conditions. Futher describes electron beam scanning over the transistor and creation of current maps of tranzistor. In the last part, the thesis deals with influence of electron beam on transport properties of graphene layer and doping of graphene layer by electron beam.
