It is established that the organization of fire extinguishing with use gel-forming compounds a promising direction to increase efficiency extinguishing, especially in multi-storey buildings and structures various functional purposes. Given shortcomings existing technical solutions for effective need develop new (spray barrels) justified. The proposed should ensure, above all, safety rescuer. Ne...

The design of large macromolecular assemblies is an endeavor with implications for protein engineering as well as nanotechnology. A hierarchic approach was used to design an antiparallel hexameric, tubular assembly of helices. In previous studies, a domain-swapped, dimeric three-helix bundle was designed from first principles. In the crystal lattice, three dimers associate around a 3-fold rotat...

Crystallographic studies of the past ten years have revealed that many outer membrane proteins and bacterial toxins are constructed on the beta-barrel motif. Two structural classes can be identified. The first class, represented by the porins, includes monomeric or multimeric proteins where each beta-barrel is formed from a single polypeptide. The second class features proteins where the beta-b...

Oak wood barrel sanitization is crucial in terms of food safety, since barrels enrich the wine aromas and taste sensation provide physico-chemical stability. The most used method sulphuring; however, there a European prohibition (Directive 98/8/CE2) that does not allow use this method. For reason, aim present work was to study an alternative technology, atmospheric pressure cold plasma (APCP) s...
