Abstract: A digital work station can be used in a radiology lab, with x-ray illuminators on an upper shelf for viewing traditional film x-rays, and computer monitors, e.g., CRTs at a lower shelf for viewing digitized x-rays. The work station is ergonomically arranged for radiologist's viewing comfort and efficiency. The height of the illuminators can be adjusted, and the shelves for the computer monitors can be adjusted also to accomodate the user preference. The monitor shelf can be level or angulated (e.g., 20 degrees) and is adjustable up and down in either orientation. The upper shelf is adjusted to minimize the gap above the monitors, and the front edge of the upper shelf maintains alignment with the sloping edge of the side walls if the upper shelf is elevated or lowered. Power outlets are provided on the front edges of the side walls just above a work shelf. The work shelf can have pull-out writing shelves.

Abstract: An electro-mechanochemical device wherein a polyelectrolyte film formed of fixed-charge, molecular groups immersed in an aqueous electrolyte comprising mobile ions is subjected to an electric field which acts to control the internal profile of mobile ions inside the polyelectrolyte film in such a way that the arrangement of the molecules that form the matrix of said film is affected.
