We use the Residential Energy Consumption Survey and ...

Introduction: The present study aimed to evaluate the impact of PbO nano and micro-sized fillers on ordinary and heavy concretes for different photon energies. Material and Methods: The MCNPX Monte Carlo code (version 2.6.0) was used for all simulations in the present study. A model of narrow-beam geometry was validated and utilized to calcul...

Let P be a non positively curved polygon of nite groups The group P acts on a contractible complex XP and we prove that this complex is a building if and only if the links have angular diameter When P has zero group theoretic curvature a geometric argument shows that the periodic apartments are dense in the set of all apartments
