Challenges for experimental methods in safeguarding and sustainability of architectural heritage
Drdácký, Miloš
The paper shortly presents typical challenges related to experimental methods and numerical simulation applied in conservation science. The main areas include proof load testing of historic structures or their replicas, material and structural health investigation and assessment of material characteristics.

Ways of Using Current Literary Education at Primary School
GREGOROVÁ, Michaela
This thesis is focused on the survey of extracurricular activities of pupils in 4th and 5th school year, related to the current Literary Education. The work is divided into theoretical and practical part. The theoretical part deals with Literary Education, its integration into the Framework Education Programme and pays attention on the 1st reading at elementary school. There are also included some methods, forms of work, learning and teaching materials and teacher?s preparation for Literary Education lessons. The main aim of the research is to discover pupils? relationship and attitude to current Literary Education and investigate their interests in extracurricular activities. There are also mentioned concrete primary school teachers? approaches and ways of using current Literary Education in practice.

Zplyňování dřeva v plazmatu a produkce plynu s nízkým obsahem dehtů

Tar content in gas produced by the gasification of biomass always plays an important role because high tar content disables some potentialities of the further treatment of the produced gas. There is a strong effort to produce gas with low tar content from this point of view. High concentrations of hydrogen and carbon monoxide also advance possibilities of the usage of the produced gas. Experiments were carried out in a reactor for plasma gasification equipped with hybrid gas-water stabilized DC torch. They confirmed that the reactor is absolutely suitable for this purpose mainly due to extremely low flow of plasma composed of argon, hydrogen and oxygen and its high inner temperature. The measurements of the tar content, using wood as a treated material, were based on SPE method and the determination of benzene and toluene in a gas phase revealed really low concentrations of tar, mostly below 10 mg/Nm3.

The Possibilities in the Efectivity of the Primary Prevention
Hermanová, Lenka ; Ortová, Marie (advisor) ; Roth, Martin (referee)
Knowledges from different researchers showed necessity to begin with primary prevention activities from childhood. This function has primarily family and home - folks, then preJschool education and schools. This thesis is about possibilities how to make the primary prevention for children and young people more effective. Particular attention is paid on the primary prevention programs in schools. But there are other factors very important beyond these activities. And it is homeJfolks, primarily family and peers but also terms in the society. There are very important protective and risk factors, which prevention tends to enhance or tries to minimise. There are a lot of methods and criterias which are very important in these programs to be consider effective. And it is very important to adapt methods and forms of these programs to the age of individual. There are mentioned information about specificity in class of age, various types of programs and methods in this essay. Further information are about the possibilities and approaches, which are indispensable to achive success in the field of primary prevention school programs. Powered by TCPDF (www.tcpdf.org)

Materials research report – Oil on canvas painting by the continuator of Petr Brandl – „The Mendicant (St. Anthony)“. National Gallery in Prague
Hradilová, J. ; Hradil, David ; Šímová, Veronika ; Patsch, J.
Pre-restoration materials research of the painting is based on microscopic (both optical and electron) analyses of grounds and painting layers in the cross-sections of fragments with the aim to identify pigments and to describe the stratigraphy of re-paints involving to choose the suitable restoration procedure. Other methods (e.g. infrared spectroscopy or MALDI-TOF) are used for identification of binding media.

Experience in the employment of geophysical methods for the investigation of embankment bodies built prevailingly of mine wastes and the observation of impacts of mining upon the rock environment
Hofrichterová, L. ; Muellerová, J. ; Müller, Karel
In the contribution are presented and generalised procedures of geophysiacal investigation applied to the solving of serious problems in the area of the Ostrava-Karviná District.

Determination of threshold values of components with protective layers
Náhlík, Luboš ; Bareš, Pavel
The contribution is focused on the influence of existing fatigue cracks in protective layers on fatigue life of structures with protective layers. The problem is solved under conditions of linear elastic fracture mechanics with help of finite element method. Is shown, that in the case of the hard protective layer on the ductile substrate represents existing crack with its tip on the bi-material interface dangerous singular stress concentrator, because of decrease of threshold values of applied loading necessary for crack propagation. Knowledge of crack propagation in protective film is of paramount importance when studying potential failure of the substrate.

Nanotechnology as potential method for recycling of PET bottles
Kráčalík, Milan ; Mikešová, Jana ; Pospíšil, L. ; Fortelný, Ivan ; Šimoník, J.
Recycling of PET worldwide is not sufficient. This issue results from decreasing molecular weight due to thermal, mechanical and hydrolytic degradation during multiple processing of polymer. The viscosity (next processability) of material can be increased by preparation of nanocomposites (formation of physical network in the polymer/clay system). The improved processing and utility properties of recycled PET were analyzed by rheology, morphology and tensile tests.

Kritérium stability bi-materiálového vrubu se dvěma singularitami
Klusák, Jan
Interfaces with a step change of material properties occur often in technical constructions. In combination with a sharp notch it usually leads to singular stress distribution in a vicinity of such a wedge. The existence of two singularities seems to be the main problem within study of this stress concentrator. The other problem is that each singularity does not correspond to particular mode of loading. The presented contribution studies stress distribution in a bi-material wedge vicinity and shows a method of solution of the problems in case of existence of multiple stress singularity
