A discussion of the agronomic theory of placing plant nutrients in the root zone of ornamental trees and plants by high pressure hydraulic injection. Definite beneficial effects of deep root injection feeding by high pressure in jection of plant nutrients have been observed in tree and ornamental plant installation and main tenance. The response outperformed conventional surface applications of...

Otitis media diagnosis can be assisted by measuring the shape of the tympanic membrane. We have developed an ear speculum for an otoscope, including spatially distributed source and detector optical fibers, to generate source-detector intensity matrices (SDIMs), representing the curvature of surfaces. The surfaces measured were a model ear with a latex membrane and harvested temporal bones incl...
