The Vistula mouth fortress in Gdańsk - suggestion for stabilisation of the walls of the Artillery Bastion
PublicationW pracy przedstawiono koncepcję ścian Bastionu Artyleryjskiego. Poważnie uszkodzona i zdeformowana murowana budowla spoczywa na zanurzonych w wodzie drewnianych skrzyniach. Stan drewna skrzyń jest zły i nie gwarantuje dalszej bezpiecznej eksploatacji obiektu. Dla ratowania budowli zaproponowano podparcie jej rzędami wciskanych w podłoże pali.

Studies of the effects of antifungal cationic derivatives of amphotericin B on human erythrocytes.
PublicationBadano nową grupę kationowych pochodnych amfoterycyny B pod kątem zależności pomiędzy ich zdolnością do asocjacji i selektywną toksycznością. We wszystkich przypadkach stosowano amfoterycynę B jako związek odniesienia. Jako miarę efektu toksycznego in vitro badanych związków stosowano wypływ wewnątrzkomórkowego potasu oraz hemolizę. Miarą aktywności przeciwgrzybowej był MIC i utrata potasu wewnatrzkomórkowego. Do oceny stopnia...

Oxygen biosensor based on carbon nanotubes directly grown on graphitic substrate
PublicationFilms of carbon nanotubes were synthesized on the graphitic substrates by CVD method in the presence of catalyst. Two different catalysts were used, that is nickel and iron, supported on graphitic substrates. The as-obtained nanotubes were analyzed by SEM imaging with EDX and Raman spectroscopy. The results revealed their multi-walled morphology. Free radical reaction was carried out in order to chemically functionalize synthesized...

Impact damage in SiO2 nanoparticle enhanced epoxy – Carbon fibre composites
PublicationLow velocity impact behaviour of nano-SiO2 enhanced carbon fibre/epoxy composites for naval applications is reported. Epoxy resin matrix was enhanced by 1- 8 wt% SiO2 nanoparticles, based on industrial surface-modified nanosilica. Impact parameters: force, deformation, energy, damage size were recorded. The most pronounced effect was damage size decrease; e.g. ∼28% recorded by infrared thermography and X-ray computed radiography...

Solubility of carbon dioxide in water: Some useful results for hydrate nucleation
PublicationIn this paper, the solubility of carbon dioxide (CO2) in water along the isobar of 400 bar is determined by computer simulations using the well-known TIP4P/Ice force field for water and the TraPPE model for CO2. In particular, the solubility of CO2 in water when in contact with the CO2 liquid phase and the solubility of CO2 in water when in contact with the hydrate have been determined. The solubility of CO2 in a liquid–liquid...
