NMI has established a non-contact aperture area measurement facility based on occlusion of a focused laser beam transmitted through the aperture being measured. The method is fast, accurate and insensitive to edge-defect-scatter. The aperture edge po

Photometric units in Australia are currently derived from power measurements made with a roomtemperature electrical-substitution radiometer. This basis has been transferred to a cryogenic radiometer. The cryogenic radiometer was used to calibrate the

A single-element, windowless InGaAs photodetector has been calibrated against a cryogenic radiometer using a diode-laser source of wavelength 1296.9 nm (standard uncertainty u = 0.4 nm). This source differs from the gas lasers usually used with cryog

S-antigen induced experimental autoimmune uveoretinitis (EAU) was produced in the Royal College of Surgeons (RCS) strain of rat which develops a photoreceptor dystrophy within 2 weeks of birth. Animals were sensitised at 60, 90, and 105 days of age:

In order to investigate the selective breakdown of the blood-retinal barrier in posterior uveitis angiograms were performed using fluorescein-conjugated dextrans (FITC-dextrans) of different molecular weights (150-kDa, 20-kDa, and 4-kDa) in two healt

Given the advances in cryogenic radiometry, area measurement is now one of the limiting factors in the realisation of radiometric and photometric units as well as radiometric temperature scales. An inter-comparison of aperture area measurements using

The diets of 12 species of demersal marine fish from various locations in the Canadian Arctic comprised a grand total of 267 prey species, mainly invertebrates. The total number of prey species taken by a single fish species ranged from 9 to 91, and

Sediment traps designed and constructed by the authors were deployed on the bottom during short periods of time at a depth of 33 m in upper Frobisher Bay. When the results were compared with data obtained from a trap set at the compensation depth (20

The effects of dexamethasone, cyclosporin A and prazosin were investigated in an animal model of retinal vasculitis. Both dexamethasone and cyclosporin A reduced the clinical and pathological signs of disease when given from the day of disease onset.

This study set out to determine whether withdrawal of cyclosporin A (CyA) in Lewis rats sensitized to retinal S antigen would precipitate experimental autoallergic uveoretinitis (EAU), and whether challenge of such animals with S antigen or an unrela
