Effective distributed user modelling in intelligent tutoring systems requires the integration of both pedagogical and domain applications. This integration is difficult, and often requires rebuilding applications for the specific elearning environment that has been deployed. This paper puts forth both an architecture and an implementation prototype for achieving this integration. It focuses on ...

Magnetic resonance imaging revealed enlargement and enhancement of the left orbital optic nerve. There were vitreous cells, but a vitrectomy specimen showed only a benign lymphocytic population.

There are some indications that this approach could be successful. Dengue-virus-resistant mosqu...
