Natural lignite from South Moravia was tested for the sorption of fluoride anion in concentration range from 0.05 to 0.8 mmol/l. The lignite removes majority of fluorides and only about 13% of sorption is reversible upon ...

Aggregation properties of hydrophobized hyaluronan (hHA) in different molecular weights and degree of substitution were studied by pyrene and perylene fluorescence method. The critical aggregation concentration (cac) was ...

Detailed balance condition for triangular isomerisation mechanism is derived from the more general permanence of atoms, consequently, it should be viewed as a special equilibrium result of mass conservation.

Synthesis and characterization of biodegradable hydrogels based on collagen modified by addition of synthetic biodegradable copolymer intended for preparation of porous scaffolds for mesenchymal stem cells used for possible ...

Změny ve společnosti se po změně systému nevyhnuly ani skladbě předmětů na školách. Je známo, že čím je sofistikovanější společnost, tím je zranitelnější a náchylnější ke kolapsu. V příspěvku předkládáme několik poznatků ...

The paper presents an experimental and theoretic research on one of factors influencing the indoor climate in dwelling rooms heated by heating systems, the vertical distribution of temperatures. The paper summarizes results ...

A new evaluation method of unsteadiness of the spray generated by an effervescent atomizer is presented. The method is based on measurements of pressure fluctuations in the atomizer mixing chamber. Measurements, made under ...

The aim of this work is to investigate sunflower plants response on stress induced by silver(I) ions. The sunflower plants were exposed to silver(I) ions (0, 0.1, 0.5, and 1 mM) for 96 h. Primarily we aimed our attention ...

Simulační řešení je v dnešní době jednou z nejaktuálnějších metod, pomocí které lze postihnout výměnu tepla, látky a dynamiku tekutin ve zkoumaném prostoru. Nejzásadnější předpoklad správného zpracovávání numerických CFD ...
