The research examines the development of women's prison writing through the journal of the Kingston Prison for Women, Tightwire. The journal enabled the prisoners to articulate their experience of prison for themselves as a specific subject-group, as women and as…

We report for the first time the results of a comparative performance study of silver-halide sensitized gelatin (SHSG) holograms recorded in the familiar Agfa 8E75 HD plates and the new BB-640 plates manufactured by Holographic Recording Technologies. High diffraction efficiency…

Technological innovation requires a technical preparation in material, financial and human resources. However, without a clear corporate culture, the technical side of technological innovation will hardly develop in a satisfactory manner.
In this light, we analyze the origin of a…

We present an available and low cost technique for the production of binary-phase diffractive optical elements designed by digital methods. We produce binary-amplitude holograms making use of a high-resolution graphic device. They are used as binary masks which are copied…

In the 19th century it was difficult for the growing number of medical practitioners in North America to access current medical literature. Various ways were suggested to solve this problem; one of them was the creation of physician-run medical library…

In this work, we have applied the fractional Fourier transform to obtain the Fresnel diffraction patterns in a theoretical eye. The FRT approach to Fresnel diffraction is easily implemented in a Gullstrand-Emsley theoretical eye, and it allows us to obtain…

The exclusionary rule which prohibits references to parliamentary materials as an aid to statutory interpretation has been applied for decades in most common law jurisdictions. The House of Lords handed down its fundamental decision in Pepper v. Hart which allowed…

A novel method for the characterization of the processing of both absorption and phase holograms is proposed. Differently from the previous models, the square root of the diffraction efficiency of the processed hologram was directly related to the amplitude of…

Optical densities before bleaching and final Lin curves of planewave phase holograms recorded in Agfa—Gevaert 8E75HD emulsions were measured for various combinations of developers (AAC, Pyrogallol and Catechol) and bleaching agents (R-9 and EDTA). To characterize the processing, the square…
