Alterations in the soluble protein patterns of tobacco and cowpea leaves following inoculation with tobacco necrosis virus
(1978-06-01)
Changes in the soluble protein composition of both tobacco and cowpea leaves following inoculation with tobacco necrosis virus (TNV R/1 : 1.5/19 : S/S : S/Fu [1]) have been investigated by the techniques of disc-electrophoresis. ...
Suppression of virus induced local lesions in plasmolysed leaf tissue
(1978-05-01)
It has been demonstrated previously that protoplasts derived from leaves which normally respond in vivo to virus inoculation, with the formation of necrotic local lesions show no such response when inoculated in vitro [1]. ...
Direct measurement of gain recovery in a saturated Nd-glass amplifier
(1978)
The temporal dependence of the gain recovery in a Nd-silicate glass amplifier has been directly observed after the passage of a short intense saturating laser pulse. The gain recovery time constant measured for ED-2 glass ...
Optical rise-time measurements on KD*P transmission-line Pockels cells
(1978)
A technique has been developed for determining the optical-transmission rise times of subnanosecond switching KD*P electro-optic modulators. Optical streak-camera data with 15-psec overall resolution and 30-psec resolution ...
Hatfield near-infrared polarimeter
(1978)
The design of the Hatfield Polytechnic Observatory's near-infrared (IJHKLM) polarimeter is described and its performance iliustrated by some representative observations on bright standard stars. Preliminary measurements ...
Short-pulse oscillator for SHIVA
(1978)
An actively mode-locked and Q-switched Nd:YAG laser has been developed with pulse widths adjustable from ~100 ps to 1 ns, stability better than ±5%, and a single pulse energy of more than 200 μJ over this range
Effects of root-infecting fungi on wheat transport processes and growth
(1978)
Aurtobasidium bolleyi and Gaeumannomyces graminis damaged transport processes and decreased shoot growth of sand-grown wheat plants only if they colonized the stele and disrupted the phloem of most roots. One week after ...
