Anterior lenticonus is an ocular abnormality that can occur in Alport's syndrome. In this study, Scheimpflug slit imaging analyses were employed for quantitative and objective evaluation of lens ...changes associated with Alport's syndrome. It was determined that while the apices of the lenticular protrusions are central in the vertical plane, they are nasally displaced in the horizontal meridian. The eccentricity and dimensions of the diameters and thicknesses of the conical aberration are highly correlated in both eyes. Lens thickness and anterior chamber depth do not differ between eyes. Densitometrically similar differences are apparent in the cortex and nuclear regions although evidence of overt opacification may or may not be present. The data strongly suggest that the physical parameters of the lenticonus are consistent with the constraints imposed by the pupil. Changes observed in the cornea and the vitreous may be associated with the syndrome.

Detergent Z demonstrated the most reliable cleaning and detergent delivery system. After the initial detergent evaluation, the data were compared against all detergents. It was found that acceptably ...cleaned items ranged from 37% to 85% per evaluation. Labor and material costs could be reduced greatly with the use of detergent Z, which had the best cleaning results. We also observed the advantage of a sensor in the detergent delivery system which can override some less obvious equipment malfunctions. Since detergent Z also exhibited the least amount of residue build-up, a savings in maintenance costs could be expected later on. The vendor of detergent Z showed great interest and concern for our department's needs and quality assurance by offering us numerous technical resources during the evaluation. One year following our detergent studies, detergent Z and its related line of cleaning products are being utilized in our hospital. We found that the four months spent analyzing detergents used in our utensil washers provided an interesting resource project that has been a positive investment in improved operations for the decontamination area. In Central Service alone, 61.7 hours a week were saved by the change in products. Quality of cleaning continues to be high. The practice of a weekly acid bath for the utensil washers has been discontinued; the acid bath will now be given when necessary, and has not been done since detergent Z was put into use six months ago. During the next fiscal year, savings of detergent, utilities and labor are conservatively projected at $30,000.
Data collected by ALEPH in the years 1990, 1991 and 1992 have been used to update a previous search for

We present results of a search for proton decays, pr arrowbar nuKsup + , using data from a 33 ktcenter dotyr exposure of the Super-Kamiokande detector. Two decay modes of the kaon, Ksup +r arrowmusup ...+nusub mu and Ksup +r arrowpisup +pisup 0 , were studied. The data were consistent with the background expected from atmospheric neutrinos; therefore a lower limit on the partial lifetime of the proton tau/B(pr arrowbar nu Ksup +) was found to be 6.7times10sup 32 years at 90percent confidence level. copyright ital 1999 ital The American Physical Society
