background & aim: in this study, is done during one-year research on blue–green and green algae for antimicrobial activity in mashhad suburb. aqueous, ether, and methanol extracts from 44 species blue – green algae and green algae were examined for antimicrobial properties against four bacteria (tow positive gram bacteria and tow negative gram bacteria) and tow fungous. material & meth...

The paper deals with monitoring and analyzing the indoor environmental parameters through remote data collection to evaluate pollution moisture infiltration effects on aircraft heritage conservation. First, based meteorological data, penetration airborne into spaces of a site (hangar) stored historic aircrafts are determined. hangar under investigation is located in Aviation museum Kbely, Pragu...

The design of thin-walled cylinders in axial compression is limited by sensitivity to geometric imperfections. This paper focuses on reducing this imperfection from a perspective. By using variable-angle composites, the load paths are tailored reduce effective area over which imperfections can initiate buckling. Continuous Tow Shearing (CTS) one such manufacturing technique. It does not cause d...

Holte, R., L. Rosier, I. Tulchinsky and D. Varvel, Pinwheel scheduling with two distinct numbers, Theoretical Computer Science 100 (1992) 1055135. “The Pinwheel” is a real-time scheduling problem based on a problem in scheduling satellite ground stations but which also addresses scheduling preventive maintenance. Given a multiset of positive integers A = {aI, a,, _.., a,}, a schedule S for A is...
