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...
Three five acre exclosures were established in 1964 to monitor
vegetational regeneration and forage productivity on a coniferous
forest site in northeastern Oregon which was clear-cut in 1963, broadcast
burned and seeded in 1964. Fence design and construction to
facilitate controlled early summer cattle grazing trials was completed
by 1965....
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....
Gas-solid chromatography often has asymmetrical elution
peaks. This is attributed to nonlinear isotherms, multi-energy
adsorption sites, and slow processes. This study utilized a stopflow
gas chromatograph with various NaOH and NaCl modified
aluminas as adsorbents and methane as adsorbate to determine the
influence of surface area and pore volume distribution...
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....
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...
This study evaluates the Earth Resources Technology Satellite-
One (ERTS-1) multispectral scanner (MSS) as a means of predicting
lacustrine trophic state and the magnitude of selected trophic state
indicators.
Numerical classificatory methods are employed to ascertain the
trophic character of 100 lakes in Minnesota, Wisconsin, Michigan,
and New York using...
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 marine vibrio ANT-500 is a typical psychrophile. The
growth range of the bacterium at 35‰ S is from a maximum growth
temperature of 13.5 C to a minimum growth temperature of -2.5 C
or less with the optimum near 7 C. The bacterium elaborates its
chitinase enzymes between the...
