We examined the human mandibular nerve to find differences in the composition of nerve fiber axons between dentulous and edentulous jaws Using Goto's modification of Masson-Goldner's method. We discovered that the edentulous jaw did not contain any large size axons, compared with the dentulous jaw. This can be considered as evidence that the larger fibers(More)
Nerve fibers of the human fasciculus gracilis were studied on 10 male cadavers aged 41-97 years using a discriminative staining method and a microscopic image-analyzing system. Our data show that the transverse areas of axons in the human fasciculus gracilis significantly decrease with age, while no significant correlation was observed between the number of(More)
In this paper we introduce a shadowing model for the volume scattering kernel component by land targets, such as vegetation, sand and soil. . The proposed BRDF model for heterogeneous land surfaces consists of three kernels, namely, an isotropic, a geometric and a volume scattering components and the new BRDF models with the shadowing volume kernel has been(More)
