Legacy software systems present a high level of entropy combined with imprecise documentation. This makes their maintenance more difficult, more time consuming, and costlier. In order to address these issues, many organizations have been migrating their legacy systems to new technologies. In this paper, we describe a computer-supported approach aimed at(More)
Swellable-core technology (SCT) formulations that used osmotic pressure and polymer swelling to deliver drugs to the GI tract in a reliable and reproducible manner were studied. The SCT formulations consisted of a core tablet containing the drug and a water-swellable component, and one or more delivery ports. The in vitro and in vivo performance of two(More)
Coccinellid pupae use an array of defensive strategies against their natural enemies. This study aims to assess the efficiency of gregarious pupation as a defensive mechanism against intraguild predators and cannibals in coccinellid. The study was designed specifically (i) to determine the natural occurrence of gregarious pupation in the field for different(More)
Zoophytophagous predators can substitute zoophagy for phytophagy to complete their development and reproduction. In such predators, variation in feeding behaviour is observed both across and within populations. This may be caused by genetic variation in diet specialization, some genotypes specializing on plant resources, whereas others rely mostly on prey(More)
In zoophytophagous predators genetically determined efficiency to exploit either animal or plant resources could lead to diet specialization, and a trade-off between fitness performances on animal and plant diet. Such a trade-off would have important consequences on the efficiency of zoophytophagous species as biocontrol agents. We estimated the genetic(More)
At the moment the huge majority of the structural parts is based on pre-preg designs and standard prepreg manufacturing technology. They are processed conventionally out of Hand Lay-up and cured in autoclaves. The cost drivers are the hand-work, the use of autoclave and the quality control. The future success of new helicopter programs is strongly dependant(More)

Protection from predators is a recognized benefit of group living for animals. The selfish herd effect implies that individuals in a central position within the group suffer lower predation than individuals at the edges of the group. The midge, Aphidoletes aphidimyza, is a furtive predator that lives within aphid colonies where it benefits from a dilution(More)
Zoophytophagous insects can substitute animals for plant resources when prey is scarce. Many arthropods feed on conspecifics to survive in these conditions. An individual's tendency for cannibalism may depend on its genotype along with its diet specialization, in interaction with the availability of alternative food resources. We compared two isogroup lines(More)
