This work aims to develop effective technology for erecting monolithic enclosing structures of buildings made expanded polystyrene concrete. As a result the research carried out, model large-panel formwork ABS plastic concreting walls with an concrete mixture was developed, representing rectangular panels size 3000 x 1200 40 mm. To ensure necessary strength and rigidity, outer side is cellular ...

Original crystal structures of even–even polyamides are introduced. They based on twisted conformations at the amide-aliphatic part links and reminiscent pleated rippled protein sheet introduced by Pauling Corey in early 1950s. Pleated sheets chiral, made two conformational isomers. have specific X-ray diffraction “profiles”. Publications describe such profiles, indicating that both variants ex...
