The sex pheromones produced by virgin females of three species of small ermine moths occurring sympatrically on the European spindle tree were analysed by gas chromatography and the synthetic compounds tested against male moths in the laboratory and field. Pheromone gland extracts of Yponomeuta cagnagellus were shown to contain tetradecyl acetate, (E)‐11‐ and (Z)‐11‐tetradecenyl acetate, tetradeca
Abstract Invasive species often have harmful effects on human activities and biodiversity. The Tapinoma nigerrimum complex includes three species that exhibit invasive traits and the ability to form supercolonies, including Tapinoma magnum and Tapinoma darioi . While these species are native to the Mediterranean basin, they have recently been reported as invasive in more northern regions of Europe
Deux jeunes filles rêvaient de visiter l'Italie: une voulait se baigner et se bronzer sur les belles plages d'Italie, l'autre avait l'espoir de rencontrer deux beaux italiens. Deux jours plus trad, elles partirent dans leur petite voiture verte. Mais malheureusement, leurs bagages ne pouvaient pas tous rentrés dans cette trop petite automobile.

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
Studies have shown that lion (Panthera leo) populations in West Africa are small, isolated and fragmented. In Nigeria, lions have disappeared from unprotected areas and are nowadays found only in parks and reserves where these populations may still decline. It is therefore urgent to obtain reliable estimates of population sizes at different localities. Direct observational surveys may either fail
Prekallikrein, the precursor to the serine proteinase kailikrein, circulates in plasma in an equimolar complex with H-kininogen. The binding to H-kininogen is mediated by the kallikrein heavy chain consisting of four "apple" domains, A1-A4, which attaches to H-kininogen with high specificity and affinity (KD = 83 UM). At least two distinct portions of the kallikrein heavy chain form this H-kininog
