A series of azo disperse dyes based on aminothienochromene were synthesized. The fastness properties of the dyed samples were measured. Most of the dyed fabrics tested displayed excellent washing and perspiration fastness and moderate light fastness.

Teoretické a experimentálne štúdium povrchových síl v disperzných systémoch V príspevku sú stručne zhodnotené výsledky priamych experimentálnych meraní povrchových síl medzi makroskopickými povrchmi so zvláštnym dôrazom na tzv. štrukturálny, resp. hydratačno-hydrofóbny typ povrchových síl. Súčasne sú analyzované povrchové sily medzi mikroskopickými časticami modelových disperzných systémov, a t...

Communication often drops dramatically between group members who move a significant distance from their work group despite the provision of mediated communication support. Although the poor quality of the communication exchange via mediated communication is certainly responsible for a significant portion of this drop, lowered suggestion, availability and comfortableness of the communication con...

The success or failure of many organisms to respond to the challenges of habitat destruction and a warming climate lies in the ability of plant species to disperse between isolated habitats or to migrate to new ranges. European semi-natural grasslands represent one of the world’s most species-rich habitats at small scales, but agricultural intensification during the 20th century has meant that ...

This study attempts to model sediment transport rates and the resulting bed evolution in a complex estuarine environment: the Gironde estuary, characterized by a high hetereogeneity in the sediment bed composition, with the presence of both cohesive and non-cohesive sediments and sand/mud mixtures. Our main objective is to extend an existing 2D morphodynamic model developped by Huybrechts et al...
