Consequence of Cement Constituents, Mix Composition and Curing Conditions for Self-Desiccation in Concrete.
This article outlines an experimental and analytical expression study on the consequence of cement constituents, mix composition and curing conditions as regards self-desiccation in concrete. For this purpose nine concretes with three values of w/c (0.32, 0.38 and 0.50), based on two types of Portland Cement, were manufactured. Five per cent silica fume was used in one third of the concretes as ca

SEX PHEROMONE OF THE CONE PYRALID DIORYCTRIA ABIETELLA
Gas chromatographic analyses coupled with electro‐antennographic detection indicated that (Z,E)‐9,11‐tetradecadienyl acetate (Z,E‐9,11–14Ac) is a pheromone component of the cone pyralid Dioryctria abietella. Gas chromatographic − mass spectrometric analyses confirmed the presence of a tetradecadienyl acetate with mass spectrum and retention index identical to Z,E‐9,11–14Ac. A receptor cell sensiti
