The heat exchange of individuals in a foraging mixed population
of Zonotrichia leucophrys and Zonotrichia atricapilla in western
Oregon is analyzed with respect to the direction of stance and
feeding location. Values for heat gain or loss in the field were
generated from a model that estimates the equivalent black-body...
A major problem of this study was to assess a model for predicting attitudes and behavior of vocational teacher trainees toward handicapped learners. A second problem was to determine whether or not both attitudes and behavior of vocational teacher trainees toward handicapped learners could be changed. The sample for this...
A procedure is described for analyzing the nitrogen content of
durable press cotton fabric at the rate of 20 samples per hour using
the Technicon Kjeldahl Auto Analyzer equipped with a continuous
digestor. This method was as good as or better than conventional
micro -Kjeldahl technique s.
Durable press cotton...
The impact that pesticides may have had on the mortality rates and productivity rates of non-game birds during the last 25 years was evaluated by studying the population dynamics of 16 species. A mathematical model showing the relationships between population parameters that yielded stable populations was developed. The information needed...
The ethyl acetate extract of the culture filtrate of the marine Ascomycete,
Leptosphaeria oraemaris (Linder) yielded a novel metabolite
designated by the common name leptosphaerin. An x-ray crystallographic
structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)-
3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine
47 and D-mannitol 44. Oxidation of 47 followed...
Gives directions to local birding areas, a checklist of Lincoln County birds, lists accidental and offshore species, and gives arrival and departure dates.
Heat transfer from a vertical flat plate in an infinite pool of
mercury was investigated. Velocity profiles were measured with a
hot-film anemometer and simultaneous temperature profiles measured
with thermocouples in this low Prandtl number liquid metal. Constant
heat flux plates at Grashof numbers of 9 x 10⁸ and 4...
