Approximately 40 to 60% of men who undergo a successful vasovasostomy have "functional failure" or failure to conceive even though active sperm are present. Factors of this functional failure include sperm abnormalities (oligoasthenoteratospermia) an

High resolution spectral scans of some Be stars, taken with an Isocon television camera, show changes in the Ha line profile in times of the order of a minute or less.

Astronomical spectra are, with few exceptions, still being recorded on photographic emulsions. These generally have the advantages of better spatial resolution and larger available area than existing photoelectric imaging detectors. On the other hand

A program of precision radial velocity measurements using a RL1872 F/30 Reticon as detector and absorption lines of HF for reference (see Campbell and Walker 1979) is being pursued at both CFHT and at DAO, Victoria. While the long term accuracy of th

Publisher Summary This chapter describes the application of an image isocon and computer to direct digitization of astronomical spectra. A system has been developed which uses a refrigerated image isocon as a detector for astronomical spectra. It is

ONLY recently-published observations permit a useful estimate of the total accretion of interstellar matter (ISM) by the Sun since it became a main sequence star. Using measurements from the OAO-2 satellite, Jenkins and Savage1 conclude that “… p

Completely time-dependent models of the expanding atmospheres of cool, carbon-rich stars were calculated. The driving force for the expansion was radiation pressure on grains. The grains were assumed to have the structure of graphite with sigma = 100

New formulae are presented to transform the CGCG magnitudes to the BS^T_ system developed by de Vaucouleurs and his collaborators. Formulae are provided for both the case where data from the Second Reference Catalogue are used and where data from the
