We sketch the HIPPOLYTOS and the KOIOS system prototypes for simple, keyword-based search in structured environmental data. Built on top of a commercial Spatial Data Warehouse software, the prototypes apply lightweight Semantic Web techniques to facilitate search in complex environmental information systems.

Nifedipine is a hypertension drug must be consumed three times a day due to its low oral bioavailability. One way of developing a controlled drug delivery system is making nifedipine microcapsules by using environmentally friendly polymers of polylactic acid and polycaprolactone via the evaporation method using oil-in-water solvents. Polylactic acid and polycaprolactone can be said to be enviro...

The structural and microwave studies of lead-free barium niobates ceramics prepared by the high temperatures solid state reaction technique are reported. The structural parameters such as the lattice constants, average crystallite size (D), texture coefficients (TC), dislocation density, and microstrain have been determined using X-ray diffraction data. Surface morphological studies were carrie...
