Arthur Ferguson MacCallan: trachoma pioneer in Egypt 1903–1923

Arthur Ferguson MacCallan CBE, MD, FRCS (1872–1955) was an ophthalmic surgeon who undertook his pioneering work in Egypt between 1903 and 1923 (figure 1). He became a world authority on trachoma; the MacCallan Classification of Trachoma, initially published in 1908, was the first grading system used to standardise the diagnosis of trachoma and was later adopted by the WHO. He also established t...

A radio continuum survey of Shapley-Ames galaxies at λ2.8 cm III. The radio – far infrared correlation

Radio flux densities of Shapley-Ames galaxies at λ2.8 cm from Niklas et al. (1995a, Paper I) and at λ20 cm from Condon (1987, C87) have been used to investigate the radio – far infrared (FIR) correlation at two different radio wavelengths. The correlation between monochromatic radio and the FIR luminosity was found to be non-linear (P2.8cm ∝ L1.09±0.04 FIR and P20cm ∝ L1.23±0.05 FIR ). Galaxies...

WOI’00: New Issues in Object Interoperability

This report summarizes the presentations, discussions, and outcomes of the ECOOP’2000 Workshop on Object Interoperability, held in Sophia Antipolis, France, on Monday, June 12, 2000. Divided into four main sessions, the workshop covered some of the most important issues related to object interoperability at different levels (such as protocols or semantics). This report has two main goals. First...
