The effect of incident angle on the quality of SIMS molecular depth profiling using C(60) (+) was investigated. Cholesterol films of ~300 nm thickness on Si were employed as a model and were eroded using 40 keV C(60) (+) at an incident angle of 40° and 73° with respect to the surface normal. The erosion process was characterized by determining at each angle the relative amount of chemical damag...

The absolute, average, and differential phase shifts that p- and s-polarized light experience in total internal reflection (TIR) at the planar interface between two transparent media are considered as functions of the angle of incidence phi. Special angles at which quarter-wave phase shifts are achieved are determined as functions of the relative refractive index N. When the average phase shift...

STUDY OBJECTIVE The aim was to examine a possible association of amount of sunshine and risk for acute closed angle glaucoma. DESIGN This was a retrospective analysis of hospital discharge registry data, linked to meteorological data for the same period. SETTING The study was a national survey using hospital discharge data for the whole of Finland over a 10 year period. PARTICIPANTS All s...

PURPOSE To determine the incidence of the primary angle-closure glaucoma at the Glaucoma Service of São Geraldo Hospital, to establish the profile of these patients and to identify the possible risk factors. METHODS Transversal study. Period of assessment: from September/2005 to August/2006. INCLUSION CRITERIA diagnosis of primary angle-closure glaucoma. EXCLUSION CRITERIA presence of cat...

This study investigated whether the long-term use of selective serotonin reuptake inhibitors (SSRIs) influences the risk of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) in the Chinese ethnic population in Taiwan.The authors retrieved the data under analysis from the National Health Insurance Research Database in Taiwan and identified 26,186 newly diagnosed depres...
