The skin armour and posterior spiracles of L1, L2 and L3 of Oestrus ovis (Diptera: Oestridae) are described and documented photographically by a scanning electron microscope. The complex and variable morphology of the attack organs of larvae of different stages makes it easier to understand better their exceeding adaptability to the host. The SEM survey has also allowed an apparently unreported...

On 23 November 1981, the Packers Consent Decree of 1920 was terminated on the joint motion of the Justice Department and Swift Independent Packing Company. This ended a long legal battle that began shortly after the decree was signed. The decree, agreed to by the old Big Five (Armour, Cudahy, Morris, Swift, and Wilson), became progressively less effective as the meatpacking industry evolved. By...

This investigation compared four conventional vehicle armour materials for performance under blast loading. The parameters measured were resistance to deformation, mechanical toughness and metallurgical microstructure. It was found that two of these, the M steel and A steel, showed the least deformation and M steel showed better shock energy absorption. B steel had high toughness but showed sig...

The World Wide Web originally provided no security services because it was not designed to support sensitive applications. As the Web evolved to become a platform for all types of Internet applications security mechanisms were added. Many Internet players, especially in the e-commerce sector, claim that the Web now can provide adequate security protection. In this paper we analyses some aspects...

The complex hierarchical structure in biological and synthetic fibrous nanocomposites entails considerable difficulties in the interpretation of the crystallographic texture from diffraction data. Here, we present a novel reconstruction method to obtain the 3D distribution of fibres in such systems. An analytical expression is derived for the diffraction intensity from fibres, explaining the az...
