Optical and lasing properties of fluorophosphate glass
(1980-07)Neodymium-doped fluorophosphate glass is a laser material newly-developed for use in high power laser fusion systems. The low refractive index (n ∼ 1.45) and low dispersion (Abbe number ∼90) of fluorophosphate glasses give ... -
Infrared and optical polarization of Markarian-421
(1981)Observations of the polarization of Mrk 421 in the V, J, and K bands are presented. The infrared radiation shows variable polarization with a range of at least 2-4%. The spectrum of the nonthermal source in the VJK regions ... -
Linear polarization of T-Tauri stars
(1981)Linear polarization observations over the wavelength range 0.44-2.2 microns are presented for six T Tauri type stars. All of the stars studied show substantial polarization in the infrared, while T Tau itself (and probably ... -
The X-ray cataclysmic variable 1E0643.0 −1648
(1981)We have used a new simultaneous IR/optical high-speed photometer on the UK IR telescope to study the recently discovered X-ray cataclysmic variable 1E0643.0−1648 (refs 1, 2). The light curve of this object obtained by the ... -
Vegetation damage during an episode of selenium pollution
(1981)Necrotic lesions were observed on the leaves of trees and herbaceous species in the vicinity of a copper refinery. Analysis of leaf samples revealed the presence of excessive concentrations of selenium and copper. The ... -

Eradication of cassava mosaic disease from Nigerian cassava clones by meristem-tip culture
(1981-01)Methods previously established for the propagation of cassava plants free from cassava mosaic disease have been applied to Nigerian clones. Meristem tips from diseased plants subjected to heat treatment for not less than ... -
NGC 206, a hole in M31
(1981-02-01)New high resolution 21 cm line observations of M31 show that the interstellar medium of this galaxy contains numerous holes in the H I distribution, some of which are clearly correlated with OB-associations. These holes ...
