Originally, the Internet delivered best-eeort service quality with respect to end-to-end delay. Recently, extensions such as RSVP have been proposed to provide guaranteed real-time services as well. Unfortunately, network resources, such as routers, do not yet fully support RSVP reservation protocols so that guarantees cannot truly be given. In this paper , we suggest to follow the paradigm of ...

Roadsides are preferential migration corridors for invasive plant species and can act as starting points for plant invasions into adjacent habitats. Rapid spread and interrupted distribution patterns of introduced plant species indicate long-distance dispersal along roads. The extent to which this process is due to species' migration along linear habitats or, alternatively, to seed transport by...

BACKGROUND Various techniques for quadriceps tendon repair have been described with biomechanical studies suggesting greater failure threshold with longitudinally placed drill holes. 1 The current gold standard for repair uses 3–4 sutures 2 passed through parallel longitudinal transpatel-lar bone tunnels. We describe a simple and reproducible technique Figure 1 Acufex ® Director™ Drill Guide po...

Scabies and head lice infestation are two common parasitic infestations seen in children. Scabies in children can present with diffuse skin lesions and characteristic intraepidermal tunnels known as burrows. The causative mites of scabies live and move inside these tunnels. Intense pruritus is common with scabies. Head louse infestation presents with scalp pruritus, the presence of live lice, a...

Les problèmes traités dans cette thèse relèvent du cadre général de la modélisation des tunnels profonds, en particulier dans les milieux viscoplastiques. L'objectif de notre travail est de combiner des travaux de recherche de type expérimental et numérique, pour aboutir à une modélisation correcte du problème de l'interaction massif-soutènement et pouvoir optimiser ainsi le dimensionnement des...

Coptotermes formosanus Shiraki and C. gestroi (Wasmann) are the most widely distributed species of the genus and occur sympatrically in the subtropics. Results of two bioassays in the current study showed that C. gestroi was more aggressive than C. formosanus. In the petri-dish bioassays, C. gestroi won most of the agonistic encounters over C. formosanus. In the two-dimensional foraging arena ...
