In this work the adsorption kinetic parameters for Fe3+ and Ni2+ ions by gyrolite are presented. Additionally, the adsoption mechanism was described by using pseudo first order and pseudo second order  equations. It was determined that the adsorption... see more

The influence of solution pH to gyrolite adsorption capacity of Zn2+ ions has been examined. Adsorption experiments were carried out in the thermostatic adsorber by stirring 1 g of gyrolite in 100 ml of Zn(NO3)2 solution containing 0.3 g/dm3 of Zn2+ ions.... see more

Pure calcium silicate hydrate – gyrolite was prepared under the saturated steam pressure at 473 K temperature in rotating autoclave. The crystal structure of synthetic gyrolite was investigated by X-ray diffraction and refined using Le Bail, Rietveld and ... see more

The several simulated X-ray diffraction patterns for calcium silicate hydrate – gyrolite were calculated with GSAS program using the structural model of natural mineral gyrolite and profile parameters values determined from refining crystal structure of r... see more


When analysing the binary opposition of life vs Death in the famous fairy tales of H.C. Andersen semiotic approach is used. The aim is to reveal how this binary opposition is used in fairy tales to create meanings, as it serves both as an element of the p... see more

This study was inspired by long-lasting debates in the Baltic states, Lithuania in particular, on the assessment results of study subjects in minority (Russian and Polish) schools, including proficiency in Lithuanian. The article presents solid evidence t... see more
