Bigleaf maple chips were pulped by the kraft, Magnetite, neutral sulfite semichemical, and refiner groundwood processes. Pulp from each process was refined in a Valley Beater and the handsheet properties of the refined pulp were compared to similar pulps made from other wood species. For the kraft process a different...
There has been a large increase in the number of three-phase
diagnostic x-ray systems installed in hospital special-procedure rooms
during the last decade. The reason for this is the capability of three-phase
systems of making possible the very short exposure times and
increased tube loading required for some of the...
This study was designed to assess the effects of approval seeking motivation and social cost upon conformity to group norms which were inconsistent with personal values. Utilizing the Asch conformity paradigm, 321 subjects were exposed to a group opinion which was contradictory to one of their personal values. The results...
The major purpose of this research was to study the in-service
programs for community college vocational instructors, and develop
guidelines for a cooperative work experience approach to in-service
staff development.
The specific objectives of the study were:
(1) To develop a research instrument capable of measuring the
agreement relative to...
Ninety-six mature pregnant Hereford cows were allotted to three
replications with four treatments. Pregnancy was determined by rectal
palpation prior to the initiation of the study. The cows were
artificially inseminated the previous spring, beginning the end of
May, over a period of 42 days to a single Angus sire....
The objective of this study was to quantify the amounts of
logging residues that are added to mountain stream channels as a
result of timber falling - logging procedures, and to evaluate
these procedures with respect to both ecologic and economic
considerations. Three falling - logging treatments were observed:
Conventional...
The silicate phases of 11 pallasites were analyzed instrumentally
to determine the concentrations of some major, minor, and
trace elements. The silicate phases were found to contain about
98% olivine with 1 to 2% accessory minerals such as lawrencite,
schreibersite, troilite, chromite, and farringtonite present. The
trace element concentrations, except...
Basalts of both Eocene and Miocene age from several groups
along the Oregon and Washington coasts have been analyzed for some
major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed
in these samples are used for comparisons within the groups studied...
Experiments were carried out to study the movement of water and
halide anions in perched water tables or saturated zones in the soil
and upper rock mantle of eight different experimental sites located
on low hills near the western border of the Willamette Valley. At each
site the experimental procedure...
Energy dependence, angular dependence, and linearity of response
to exposure levels were studied for the thermoluminescent
dosimeter used in an environmental monitoring network. The dosimeter
consisted of a manganese activated calcium fluoride phosphor (Ca F₂:
Mn) bonded to a helical heating element and encapsulated in a gas filled
glass tube....
