Chromatin DNA sequences intimately associated with the "core"
of the basic, repeating chromatin subunit are shown to be relatively
resistant to digestion by micrococcal nuclease. Chromatin DNA
sequences lying between adjacent chromatin subunits, as well as
DNA sequences in regions of chromatin which are free of chromatin
subunits, are subject...
The central question of this study was to examine the moral orientation and the role of self in subject generated moral dilemmas for information on the developmental and cultural forces contributing to the etiology and maintenance of eating disorders in college women. The research was based on the theories of...
Research on the topic of learning styles has
revealed the positive impact that implementation of a
learning styles program can have on the education of
America's youth. Yet for many districts in the state
of Oregon, implementation is hindered by a lack of
available funds and personnel trained to do...
Two trials were conducted to evaluate changes in the quantity, quality, and moisture of available forage in the pasture, and shrub utilization by cattle during a 30-d late summer grazing period (Trial 1) and the effect of cow age (experience) on grazing distribution and diet composition (Trial 2) in mountain...
Morphological changes in five clonally propagated genotypes
of Agrostis L. resulting from variations in environment were
studied in six natural environments extending from southern Oregon
to northern British Columbia. These same clones were also subjected
to four different cutting heights in turf plots. In addition to
the field experiments, they...
This study assessed the effects of thinning on arthropod communities on understory plants in the Central Oregon Coast Range. Arthropods were sampled from five understory plants in five pairs of thinned and unthinned, young (50-80 yrs), managed Douglas-fir stands, from late May to mid-July of 1998. Vine maple (Acer circinatum),...
Prothoracicotropic hormone has been partially purified
from whole heads of tobacco hornworm larvae, Manduca sexta.
Activity was followed with a larval bioassay. Activity was
purified 4400 fold from crude extracts. The hormone was
found to be a heat-stable polypeptide with an approximate
molecular weight of 25,000 Daltons. The hormone has...
The opening of the South Atlantic between 140 and 90 m. y. B. P.
occurred about two poles of rotation. The initial pole of rotation was
maintained until Africa and South America were completely separated.
The subsequent removal of restraints imposed by the pre-existing
structure of Africa and South America...
Increased energy costs have prompted the rural village of Galena, Alaska to explore viable alternatives for heat and power generation. Continued dependency on petroleum products will cause the community’s economic driving force, the Galena Interior Learning Academy (GILA), to face uncertain operability. A wood-fired boiler is scheduled to be installed,...
