The practice of dietetics has changed over the
past several years to include an increasing number of
dietitians working in private practice. The 1986 census
of The American Dietetic Association identified
2,383 (4.3%) of the membership as active in the Consulting
Nutritionist in Private Practice group. Private
practice opportunities have...
The black and white pattern formed when an individual word is
printed on a page was analyzed by the Fourier transform. The Fourier
transform produces a sequence of sinusodial functions, usually called
spatial frequencies, whose amplitudes depend upon the particular
pattern analyzed. These amplitudes were examined to determine if the...
Documentation of the side effects of pesticides on
arthropod natural enemies has expanded rapidly since the
1950's as part of an increase in non-target side effects
literature. Most reviews have been based on empirical
analysis of selected literature. The SELCTV database was
developed to make a larger information base accessible...

various demographic, structural, organizational, and
operational factors and the success of nonprofit
foundations affiliated with two-year technical and
community colleges in Canada. Three aspects were
specifically examined: (1) a descriptive analysis of the
two-year technical and community college foundation in
Canada; (2) Pearson product-moment...
The cormorant/fisherman issue is not limited to Tillamook County in 1988-1989 but is symptomatic of a widespread conflict of some fishermen with fish-eating animals. Predators, specifically cormorants, have been blamed for the "ruin" of the Tillamook fisheries, but the effects of cormorant predation have been exaggerated. Actually, current salmon and...

Three distinct studies using an ethidium bromidedigitonin
fluorometric assay were conducted to determine
if the fertilizing ability of individually caged broiler
breeder males (BBM) could be enchanced by nutrition,
breeding and semen extender viscosity.
The first study evaluated the effects on the
spermatozoal quality of BBM by feeding corn-soybean meal...
A model is developed that allows the prediction of the stress-strain
distribution in a mixed carbide sphere pac fuel pin during
irradiation. The model is coupled with a previously developed model
for the thermal behavior of the pin. The one-dimensional (radial at
various axial locations) solution is for quasi-steady pin...
A sample of fish remains from two late-prehistoric archaeological sites on the central coast of Oregon were analyzed to partially evaluate two models of aboriginal subsistence-settlement systems. One model is based upon ethnograhpic data, primarily Drucker's (1939), for Yakonen speakers collected in the late 19th and early 20th centuries. The...
The primary purpose of the present study was to investigate the effect of peer presence upon the health-related physical fitness test scores of college students. A total of 312 undergraduate college students, 156 males and 156 females, 18 through 29 years of age, randomly selected from the physical education activity...
Perennial ryegrass (Lolium perenne) - white clover
(Trifolium repens) hill-land pastures were grazed at
different times in the winter to study the effect of time
of winter grazing on plant response and forage production.
The same pastures were grazed by sheep once in early
December, January, February, March, or April...
This study investigated the design of a new type of
postsecondary educational institution for Venezuela that
would meet the vocational education and training needs of
postsecondary students and the skilled labor demands of the
nation. Venezuela's educational system was analyzed to
delineate a center for a suitable two-year vocational
technical...
The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...
Middle School represents a period of transition for the
students. This transition is present not only in physical change,
intellectual change, and emotional change, but also in terms of
the type of reading instruction these students receive. One
approach to reading instruction moves from a direct approach
focusing on specific...
Four studies were conducted in the llama (Lama glama) evaluating changes in reproductive physiology, vaginal cytology, and growth. Study I. Temporal changes in vaginal cytology were correlated with alterations in serum estradiol -17β and progesterone concentrations. A 2 * 2 factorial study examined the treatment effects of a) concurrent male...

Fifteen sand samples from beaches along the Pacific
North were analyzed for their elemental content by the
method of instrumental neutron activation analysis
(INAA). A separation technique was employed to separate
the zircon (a heavy non-magnetic mineral with a specific
gravity of 4.67) from the rest of the sample. This...
Of great benefit, but not limited to seafloor mineral
exploration, is a technique that fairly rapidly determines the
composition of a drilled vibracore (in a time comparable to the time
involved in obtaining the core). The rapid assessment is desired to
predict whether a given region warrants further exploration by...
Part I describes the synthesis of bis(fac-S)((tris)2-aminoethanethiolatoiron( III))iron(III) chloride. The compound was first discovered during an attempt to prepare a ternary complex of iron, thiolate and pi-acid ligand.
