Five Years of Progress in Disability Protection

Twenty-five years of progress.

Thirty-five years of progress in the study of MSH.

In this paper, initial work on MSH at Dr. Lerner's laboratory in Portland, Oregon, from 1952 to 1954 is presented. The development of an in vitro bioassay method enabled us to show increased urinary excretion of MSH in Addison's disease. The ability of MSH to increase skin pigmentation in man was also demonstrated. Subsequent work on MSH during the past thirty years is reviewed, such as charact...

Twenty-five years of progress in bilirubin metabolism (1952-77).

This review deals with the development of our understanding of the chemistry of bilirubin and its glucuronide derivatives during the years 1952-1977. It examines the relation between haem metabolism and bilirubin formation and our present knowledge of hepatic transport of bilirubin. The heterogeneity of familial hyperbilirubinaemia is discussed.

Twenty-Five Years of Progress in the Three-Nucleon Problem

Twenty-five years ago the International Few-Body Conference was held in Quebec City. It became very clear at that meeting that the theoretical situation concerning the He and H ground states was confused. A lack of computational power prevented converged brute-force solutions of the Faddeev or Schrödinger equations, both for bound and continuum states of the three-nucleon systems. Pushed by exp...

A Perspective on Computer Progress in the Last Five Years

The paper surveys recent progress under the following headings: workstations, processor design, parallelism, local area networks, UNIX, computer security, electronic mail and facsimile, and programming languages. It updates an earlier paper published in 1984 [1]. Five years ago personal computers were already enjoying a great success. The personal computer, or rather the microprocessor on which...
