This investigation expands on earlier methods of using surface polarization reflection (SPR) to characterize the first few monolayers of a surface. Past research measured intensities of light reflecting off an SiO₂ optical flat inside a vacuum. Pressure of applied gas was changed to view a change in reflection. In an...
Out of 53 queens captured for initiating colonies in the
laboratory, 33 laid eggs (62 percent), 29 of these produced colonies
(55 percent), and 14 produced queens (26 percent). A behavioral model
depicts the activities of queens from spring emergence through colony
development. A discussion of its application to bumble...
Purpose
The study was designed to test the effectiveness of a counselor
training experience which used pre-recorded client statements as the
instructional medium. The principal objective of instruction was to
teach counselor trainees to differentiate between the affective and
cognitive content of client statements and to respond in ways which...
I. The Effects of Sire Breed, Forage Availability and Weather on the
Grazing Behavior of Crossbred Ewes.
Thirty nonpregnant, nonlactating crossbred ewes, six per sire
breed (Suffolk, Clun Forest, Dorset, Polypay and Border Leicester),
were observed grazing together in a 0.87 ha grass-clover pasture for
six days over a two-week...
A dynamic model of a refrigerant boiler has been produced by
the use of distributed parameter modeling techniques. A number
of elementary cases were studied and were used as an aid in the
final model formulation. Modeling using distributed parameters
employed the use of mesh equations which were then reorganized...
Gram positive cocci isolated from Oregon wines
were characterized and their relative malate fermentation
abilities compared. They were heterofermentative,
catalase negative, and facultatively anaerobic. Glucose,
fructose, cellobiose, maltose, ribose, trehalose, salicin
and esculin were fermented by all strains. Arabinose was
fermented weakly but lactose, raffinose, sucrose, xylose,
rhamnose, mannose and...
Partly laminated sediments on the upper continental
slope (200-600 m) off central Peru contain a diverse assemblage
of fish debris, diatoms, and the remains of a variety
of other nektonic, planktic, and benthic organisms. Approximately
97 percent of the fish scales recovered from
the best preserved cores come from the...
