An oscillating plasma glow discharge detector for gas
chromatography is used to obtain fingerprint information
about an analyte by combining both the average cell
current and oscillation frequency signals. Five homologs
each of the n-alkanes, 1-alkenes, 1-alkynes, 2-ketones and
aldehydes are studied. Although triplicate determinations
had some scatter due to...
Rapeseed is grown for its oil and meal, and as a cover crop. Rapid fall growth captures part of the available soil nitrogen, which otherwise might be lost to leaching, and provides good ground cover over winter.
This study compared wives defined as underemployed by educational
mismatch with not underemployed wives on four major predictor variables--
relative market work advantage; degree of competition in the
female labor market; time demands from family members; and assistance
with childcare and other housework. The data were from NE 113, An...
Cereal grains are grasses and may have a prostrate, semierect, or erect physical stature. All have fibrous root systems.
Barley, oats, triticale, and wheat are each comprised of hundreds of varieties whose growth characteristics vary considerably.
Cereal rye is an erect annual grass with greenish blue, flat blades and an extensive fibrous root system. It resembles wheat, but usually is taller (3–5 ft) and tillers less. Flowering is induced by 14 hours of light in spring.
The purpose of this qualitative study was to describe and communicate a student-constructed model of student services for electronic distance education (EDE). This study seeks to answer the following questions: Do students enrolled in EDE perceive a need for student services? If not, why not? Which services do students want/need?...
Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with CO₂ precision plot sprayers. Unless otherwise indicated, preplant...
Results from vegetation management trials involving horticultural crops conducted during the past year are compiled and reported by faculty members of the Oregon Agricultural Experiment Station, the Oregon State Extension Service, and colleagues who cooperated from adjacent states along with local enterprises. This work was conducted throughout Oregon and involved...

The purpose of this thesis was to gain insight into why female college students initiate smoking. This study examined the major factors influencing the formation of such habit among this group. The tool used to study these factors was the questionnaire. Questionnaires were administered to randomly selected female students on...

This study re-examines how variations in market power
across industries affect the relative number of females and
males hired in a given occupation. The study builds upon
similar work done by Sharon Oster (1975) to examine the female
to male wage differences. Both market power and human capital
factors such...
Self-regulation in early childhood encompasses higher-order executive function processes and lower-order emotional responses that enable children to navigate the classroom environment. Although self-regulation and executive functions are overlapping constructs, self-regulation represents a broad assessment of children’s ability to call upon executive function processes in order to meet contextual demands. Prior...
