Efffects of hypothalamic lesions on the food intake of the goldfish (Carassius auratus)
(1978)
Goldfish were trained to perform an operant response in order to obtain food, thereby allowing the food intake to be accurately determined. The normal daily food intake was established for each fish before it was given a ...
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 ...
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 ...
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 ...
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
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 ...
