Studie vhodného uspořádání magnetických obvodů pro realizaci magnetokalorického efektu
The paper is stimulated by one of very prospective physical do-mains – magnetic cooling based on the magnetocaloric effect. Successful realization of this effect requires a magnetic circuit with permanent magnets producing very strong and uniform magnetic field and the paper deals with arrangements of such circuits. I…
Particle Systems
The subject matter of this work is a concept and implementation of an extension of Particle Systems API. The extension provides a means by which it is possible to split a 3D model defined by its boundary representation into pieces with a geometric plane and render them using the particle system being extended. Because…
Influence of spectral properties of combined random loading on fatigue life
The contribution deals with an influence of power spectral densities of random loading processes on fatigue lives of structures. Experimental results of uniaxial loading are presented. A philosophy of multiaxial tests, which will be carried out in the new grant project, is also discussed. It is expected that a new num…
A comparison of insulative properties and financial costs between materials of organic origin and insulated sandwich panels
The topic of this publication is a comparison of insulated sandwich panels and materials of organic origin - wood based materials. There were compared insulative properties, lifetime and finacial costs of these materials.
Vlastnosti částic dvoufázového prášku na bázi Fe-Al stříkaných metodou WSP
Paper deals with properties of the in-flight state powder particles subjected to spraying via water stabilized plasma torch. Properties such as chemical and phase composition and characterization of the microstructure are described. Severe evaporation of Al is observed.
The facilities of usage of immunolocalisation methods for field emission scanning electron microscopy
In this bachelors thesis I compare and contrast the FESEM (field emission scanning electron microscopy) with the TEM (transmission electron microscopy) for the immuno localisation of antigens in biological specimens. More attention was paid to the use of the FESEM due to the recent technological improvements, allowing…
Land snail shell degradation in forest environment
Experimental shell degradation of nine common Central European pulmonate snail species in forest ecosystems in the Czech Republic was investigated. Model shells were deposited for 6, 12, 24 and 36 months in leaf litter of six different places; than removed, dried and photographed. Set of alternations was analysed by C…
Lignite deposits between Moravská Třebová and Kunštát, by Uhelná, Dolní Životice by Opava and in neighbourhood Brno
The petrographical and elemental composition and technological parameters of Cenomanian and Miocene lignite were discussed.
Klasická nukleační teorie a modelování kavitačních jevů
The description of the nucleation of bubbles and their growth in cavitation processes suitable for computational fluid dynamics (CFD) simulations is investigated. The number of newly created bubbles and their sizes are treated empirically in most of the numerical codes. We show that the Classical Nucleation Theory (CN…

Proceedings of the 4th Czech-Japan-China Cooperative Symposium on Nanostructure of Advanced Materials and Nanotechnology (CJCS’09)
ISI ASCR in Brno is primarily a methodological institute creating and developing new experimental methods for several areas of physics, chemistry and biomedicine. Among these, methodology of the scanning electron microscopy occupies an important position. One of long time projects concerns microscopy with very slow el…
Biogenic calcite structures in Green Lake, James Ross Island, Antarctica
Microbial carbonates (calcification) have been reported in Antarctic lakes in James Ross Island with unusual periphyton communities (cyanobacteria and green algae). This is the first record of cyanobacterial thrombolite community in Antarctica.
Novel thin scintillation films for 2D imaging screens
In this work we studied properties of Ce doped garnet scintillator layers (CexLu3-xAl5O12, CexY3-xAl5O12). They were prepared by liquid phase epitaxy. Studied materials show fast response, high quantum efficiency and good chemical and mechanical stability. Thus they are ideal for use in devices for 2D imaging. We meas…
Dispersoids in aluminium alloys
As a preparation for the study of dispersed particles in the aluminium alloys the ALCHEMI method was tested on a simple model material. This method combines the X-ray spectrum analysis and the dynamic diffraction to provide the information on site occupancies. The site preference of Cr in the Fe3Al and FeAl materials…
Polyvinyl chloride catheters with repressed migration of plasticizers
Impart flexibility and desired softness of polyvinylchloride (PVC) – one of the most widely used polymeric materials for medical device production – is achieved by addition of appropriate amount of plasticizer, usually di(2-ethylhexyl phthalate) (DEHP), into polymer matrix. DEHP is not chemically bonded to PVC and mig…
Synthesis of the 3rd generation of photosensitizers based on azaphthalocyanine core
CHARLES UNIVERSITY IN PRAGUE FACULTY OF PHARMACY IN HRADEC KRÁLOVÉ DEPARTMENT OF PHARMACEUTICAL CHEMISTRY AND DRUG CONTROL Title: Synthesis of the 3rd generation of photosensitizers based on azaphthalocyanine core. Author's name: Vendula Stará Year: 2009 Abstract: Photodynamic therapy (PDT) is a new significant treatm…
Simulation of the crack growth in the weld of the polyolefin pipes
The aim of this work was to study the effect of the material properties change due to the butt welding on the stress intensity factor in polyolefin pipe. The gradient change of the Young’s modulus was assumed. The crack was located in the middle of the affected zone. The stress intensity factors estimated in both grad…
Comparison of Nuclear Energy Policy in the Czech Republic and France
This paper studies the nuclear technology and evaluates the most likely technical developments to come until 2030. It examines the features of Czech and French nuclear programs, compares the structures of nuclear sectors and estimates the advantages & drawbacks of further developments in both countries. The paper asse…
