In recognition of the need to determine dynamic properties of naturally frozen materials, a research project was conducted to measure the dynamic properties (dynamic moduli and damping ratio) of naturally frozen wedge ice samples obtained from the Fairbanks, Alaska area. Cyclic triaxial and resonant column test systems were employed to...
The purpose of this study was to examine and compare the effectiveness
of two approaches in nutrition education instruction among culturally
diverse adolescents: the teacher-oriented lecture approach and the
student-oriented instructional design approach. The study was
designed to help culturally diverse students gain a basic
understanding of practices that promote...
Four instruments were developed to assess sex education
attitudes and skills of parents. The Parental Perception of
Preadolescent Child (PPPC), Parental Attitudes Toward the Sex
Education of Children (PATSEC), Topic Checklist (TC) and
Index of Challenging Questions for Parents of Preadolescents
(ICQPP) provided measures on how parents perceive maturity
and...
The incidence and duration of breast feeding were determined
via telephone questionnaires from a sample of 95 women who delivered
healthy infants during the month of September 1982, in the greater
metropolitan area of Portland, Oregon. This sample was limited in
that the women were married, predominately white, over 25...
Space flight results in loss of mass and function in skeletal
muscle. Data from manned flights and animal biosatellites give
evidence of possible changes in neuromuscular interactions.
Components at the neuromuscular junction are a potential site of
action for this space-induced muscle atrophy. We examined the
nicotinic acetylcholine receptor population...
Experiments were conducted to determine: (1) effects of pretransplant
stolon formation on performance of potato transplants in
the field and greenhouse; (2) effects of parent plant nodal position
on productivity of rooted nodal cuttings; and (3) relationships
between photoperiod and stolon formation.
The effects of early stolon formation on Russet...
Field and growth chamber experiments were conducted to
determine chloride effects on the progress of stripe rust disease
caused by Puccinia striiformis West., and to investigate turgor
potential as the mechanism of the chloride effect.
Seven winter wheat (Triticum aestivum) cultivars were
grown in the field in 1982 and 1983...
Defining the inelastic behavior of nail joints is essential
in the development of a rational design procedure of wood-stud walls.
Prediction equations were developed for the inelastic behavior
of joints commonly found in wood-stud walls. The equations relate
three elastic moduli that define the average inelastic joint stiffness
to the...
