The infection of cucumber mesophyll protoplasts with tobacco mosaic virus
(1976)Protoplasts from the first leaf mesophyll of cucumber plants were isolated by an 18 hour combined petinase/cellulase treatment. Conditions favouring the infection of these protoplasts with tobacco mosaic virus (TMV), and ... -
Who's Who in D.H. Lawrence
(Taplinger Publishing Co, 1976) -
Aspects of Growth and Metabolism in a Suspension Culture of Acer pseudoplatanus (L. ) Grown on a Glycerol Carbon Source
(1976)A suspension culture of Acer pseudoplatanus cells was transferred from medium containing 2% (w/v) glucose to an identical one containing glycerol at 2% (w/v) as the sole carbon source. The patterns of cell number increase, ... -
Investigations on the infection of cucumber mesophyll protoplasts with cucumber mosaic virus
(1976)Isolated protoplasts from the first leaf mesophyll of cucumber plants have been successfully infected in vitro with cucumber mosaic virus (CMV). Virus instability before, during and after inoculation of the protoplasts ... -
Interpulse interference and passive laser pulse shapers
(1976-12-01)Passive pulse shapers including Fabry-Perot etalons, double-etalons, and classical beam splitters are examined both theoretically and experimentally for their temporal behavior. For temporally and spatially overlapped ... -
Pulse shaping for laser fusion
(1977) -
Serial change in group psychotherapy
(1977) -
Ribonucleic acid synthesis by chromatin isolated from Phaseolus aureus Roxb. : The effect of endogenous ribonuclease
(1977-01-01)Chromatin was isolated from the hypocotyls of Phaseolus aureus Roxb. and assayed for endogenous RNA polymerase (EC 2.7.7.6) activity in vitro. The molecular size of the RNA product, measured by polyacrylamide gel ... -
Pulse stretching and spectroscopy of subnanosecond optical pulses using a Fabry-Perot interferometer
(1977-04)A Fabry-Perot interferometer has been used to produce optical pulses of variable width from a short gaussian input pulse. Pulse stretching of two to five or more times the original pulse width is possible provided a longer ... -
Improved isolation and culture methods for cucumber mesophyll protoplasts
(1977-05-01)Improved methods for the isolation of large numbers of viable protoplasts from cotyledons and first leaves of two cultivars of cucumber, Cucumis sativus L. cv. Ashley and China are described. Short-term isolation methods ... -
Shaping pulses for fusion
(1977-06-01)Two approaches to the creating of pulse-shaping techniques that meet the requirements associated with operation of a large fusion laser are examined. These techniques are passive pulse-shaping with double-etalone devices ... -
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 ...
