Performance   evaluation in regular periods is one of the ways in which organizations can   evaluate their performance as well as weak and strong points unifiedly and   precisely. These days, mathematical models are also used to evaluate the   efficiency and productivity of various units. These units are a collection of   education, research and service activities as input and output factors an...

this research was conducted to investigate the effect of acetylation and type of resin on fire resistance of one and three layered populus particleboard. populus particles were acetylated at three levels of acetyl content (wpg of 0, 8.39% and 17.27%). in manufacturing of one and three layered boards with acetylated particles in all thickness or surface of the boards two type of resin, urea form...

Abstract This paper presents experimental and numerical results of an investigation into the thermal structural behaviour innovative modular steel system, which includes cellular beams, that was tested in a 1-h standard fire scenario while loaded. The system consists 5.66 × 3.8 m rectangular frame, with profiled sandwich decking (SD) attached, comprises (a) decking, (b) fibre cement, (c) calciu...
