The critical angle technique is modified for the accurate measurement of the refractive index of bio-optical materials. Based on the analysis of reflection from the boundary of the material as a function of incident angle and polarization direction, the critical illumination angle is obtained by numerical differentiation of the reflection curve. As an example, the dispersion curve of bacteriorh...

We report a patient with traumatic glaucoma with features of unilateral pigment dispersion. This rare form of secondary glaucoma has only been reported twice previously, with both patients demonstrating angle recession, indicating associated damage to the trabecular meshwork. To our knowledge, this is the first such case reported in which angle recession was absent.

Facility dispersion seeks to locate the facilities as far away from each other as possible, which has attracted a multitude of research attention recently due to the pressing need on dispersing facilities in various scenarios. In this paper, as a facility dispersion problem, the geometric maximum k-star problem is considered. Given a set P of n points in the Euclidean plane, a k-star is defined...

Measurements were made of the femoral shaft/neck angle (CCD angle) in 106 human foetuses, aged from 16 to 38 hbd, using a "FEM-GEO_03" computer program. The values of the CCD angle in the group under examination were: mean = 140.48 degrees, SD = 6.95 degrees, max = 157.90 degrees, min = 113.93 degrees. No significant differences were found in CCD angle size between male and female foetuses or b...
