Perceptions of Teachers of Students with Visual Impairments regarding Assistive Technology: A Follow-up Study to a University Course

This follow-up study of 60 nonworking persons with visual impairments who contacted a vision rehabilitation agency for vocational placement services over a five-year period found that the absence of other health or physical conditions and being unemployed one year or less were significant predictors of job-seeking behavior.

Main Components

Scanning microscopy was used to study the surface of human gallstones and the surface of fractures. The specimens were obtained by operation, washed with water, dried at room temperature and shadowcasted with carbon and aluminum. Most of the specimens belong to patients from a series of X-ray follow-up study, examined during the last twenty years. So it was possible to evaluate approximately the age of these gallstones and to get information on the intensity of growing and solving.Cholesterol, a group of bile pigment substances and different salts of calcium, are the main components of human gallstones. By X-ray diffraction technique, infra-red spectroscopy and by chemical analysis it was demonstrated that all three components can be found in any gallstone. In the presence of water cholesterol crystallizes in pane-like plates of the triclinic crystal system.
