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 in UndeterminedThe dynamics of agglomeration externalities along the life cycle of industries, Regional Studies. This paper investigates the changing roles of agglomeration externalities along the industry life cycle. It is argued that industries have different agglomeration needs in different stages of their life cycles because their mode of competition, innovation intensity, and learnin
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
Stroke causes direct structural damage to local brain networks and indirect functional damage to distant brain regions. Neuroplasticity after stroke involves molecular changes within perilesional tissue that can be influenced by regions functionally connected to the site of injury. Spontaneous functional recovery can be enhanced by rehabilitative strategies, which provides experience-driven cell s
