The role of detritivores in the conversion of allochthonous
leaf material in two small streams in the Cascade Range of Oregon
was studied. Their importance in relation to other consumers was
estimated from emergence and benthic standing crop data.
Ingestion rates and efficiencies of utilization of bigleaf maple

This paper describes the system design of a Fortran hardware
compiler which converts the original code of a source program into
an intermediate code. This code contains features that allow easy
machine code generation. An evaluation is first made on the marketability
of such a system and then a brief...
The development of Easter lily Lilium longiflorum Thunb.
'Ace' bulblets from scales was used to study the influence of scale
pre-cooling, growing temp, and daylength on scale initiation,
scale "filling" (bulbing), and scale leaf formation. The development
of 'Croft', 'Ace', and 'Nellie White' daughter bulbs in field-grown
yearlings was also...
Ecological and production studies of Prosimulium caudatum Shewell, P. dicum Dyar and Shannon, Simulium arcticum Malloch and S. canadense Hearle (Diptera: Simuliidae) were made in 1971 and 1972 in three streams near Corvallis, Oregon. The purpose of the study was to characterize the biology and population dynamics of larvae, and...
The purpose of this study was to compare the effectiveness of
television lectures and television lectures reinforced with two types
of recorded media (audio-slide kits and super 8mm movies with
sound) with the traditional lecture method of teaching three selected
lessons of clothing construction. The research was conducted winter
and...
