Similarities in the soluble protein profiles of leaf tissue following either a hypersensitive reaction to virus infection or plasmolysis
(1981-03-01)
Cucumber cotyledons and cowpea leaves both react hypersensitively to tobacco necrosis virus (TNV) infection. The soluble fractions of these tissues, following virus-elicited necrosis, contained apparently novel proteins. ...
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 ...

Alphanumeric category effects - evidence against the sufficiency of a localization explanation
(1981)
The experiment utilized a serial choice reaction time (RT) paradigm in which only one alphanumeric stimulus was presented per trial, and the target set consisted of a single identified item. The categorical relationship ...
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 ...
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 ...
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 ...
