Numerical Computer Perpheral Interactive Device With Manual Controls, James C. Fletcher, Arthur I. Zygielbaum, Stanley S. Brokl

School of Natural Resources: Faculty Publications

A computer peripheral device is disclosed which in cludes a joystick whose displacement from a center position along two axes X and Y in either a plus (+) or a minus (-) direction is sensed. The displacement magnitude in either direction controls the rate of clock pulses provided by a variable frequency clock. The clock pulses from the two clocks are accumulated in two separate counters, whose contents are dis played. The contents of the counters are suppliable to a computer to update the contents of specific cells which define the position of a cursor on a display which is …

Concentration Of Co, In The Air Above A Sugar Beet Field, K.W. Brown, Norman J. Rosenberg

School of Natural Resources: Faculty Publications

The concentration of CO, in air sampled above a sugar beet crop was measured during July, August, and early September 1966 at Scottsbluff, Nebr. During July the mean daytime concentration decreased from 310 ppm to 283 ppm as the leaf area index increased from 0.8 to 4.0. Only small deviations from the mean daytime Concentration of 283 ppm occurred during the remainder of the season. The mean nocturnal concentration during this period was 320 ppm and was more variable than the daytime concentration. The daily amplitude of concentration averaged 70 ppm and was as great at times as 100 ppm. …

Agroclimatic Calendar For Nebraska, R. E. Neild

Crops are planted so growth, development and harvest correspond closely to the season most favorable for yield and quality. With exception of fall-seeded small grains and some forages, most Nebraska crops are planted in the spring when temperature and precipitation are increasing.

Ultrasonic Tracking Of Migratory Fishes With An Internal Tag, Ross M. Horrall, H. F. Henderson, A. D. Hasler

School of Natural Resources: Faculty Publications

First paragraph:

A small ultrasonic tag, 9 mm by 40 mm in size, has been developed by members of the fish orientation group at the University of Wisconsin. The tag emits a continuous signal at approximately 65 kc/sec. The signal is received via a directional hydrophone and a high quality communications receiver. Tracking ranges of up to 1 km have been obtained. The placement of the tag is internal: either into the stomach or into the body cavity of the fish. The tags and tracking equipment have been successfully employed in studies on the open water movements and orientation of …
