A vegetation study was made of four coastal marshes near Juneau,
Alaska. Results confirmed earlier studies' findings in southeast
Alaska that communities or assemblages of species can be identified
but from marsh to marsh these assemblages appear to have no consistent
relationship to each other or to environmental "factors" such...
Studies were conducted in the vicinity of Mount Tolman
on the Colville Indian Reservation in eastern Washington in
order to identify vegetation habitat types of the area.
After field studies were completed, Daubenmire's keys to
habitat types of eastern Washington (1968, 1970) were used
to determine habitat types of the...
The objectives of this study are to: 1) study the variations
among stands of old-growth Sitka spruce forest located within a relatively
restricted geographical area, 2) determine the relationship between
species distribution, vegetational pattern, and such site factors
as slope and aspect, and 3) ascertain the abruptness of phytosociological
change...
In an effort to describe the plant communities and
succession of the Oregon coastal grasslands, vegetation
and environmental data were collected from 75 stands at
24 separate locations ranging from Cape Falcon in Tillamook
County to Cape Ferrelo in Curry County. The vegetation
data consisted of cover and frequency values...
Grassy balds are meadows that occur on or near the summits of montane peaks and ridges. The sites on which balds are located generally fall within the climatic tolerance ranges of associated tree species. This study evaluates the stability of a forest-meadow transition zone of such a bald on Marys...
An important task of a Variable Speed Generation (VSG)
system is the capability to maintain and control the terminal
voltage at some desired value as determined by the
reactive power dispatch strategy.The main objective is to
design a sub-optimal fixed-parameter controller in the
sense that constraints with respect to practical...
Phage-insensitive Streptococcus cremoris starter strains were
selected by assaying cheese whey against potential starter
strains. Six strains were selected and characterized for continual
use in cheesemaking. Upon phage-infection, strains were removed
from the blend. Cheesemaking continued with remaining strains. A
phage-insensitive, fast-acid-producing mutant of the infected
strain was isolated and...
Several methods for estimation of the potential
shelf-life of pasteurized fluid milk products were evaluated
for their efficacy in this investigation. These methods
were evaluated and compared to sensory, biochemical and
bacteriological indices through a series of experiments
conducted on different brands of commercially pasteurized
fluid milk. The methods evaluated...
The effect of reducing sodium chloride in Cheddar cheese was
studied. Milled curd from a split-lot was salted at selected NaCl
concentrations and analyzed through aging by sensory and rheological
tests. Estimation of differences in compositional analysis, lactic
acid populations, degree of proteolysis, water activity, and pH were
also determined....
Heat resistant sporeforming psychrotrophic bacteria were
isolated from raw milk samples from 59 Grade A farms in Oregon.
Forty-nine of the 59 (83%) raw milk samples in this survey
contained sporeforming psychrotrophic bacteria; isolates from
twenty-four (40%) of the samples exhibited proteolytic properties. Populations of sporeforming psychrotrophic bacteria ranged
from...
The Ataspaca prospect is in the Cordillera Occidental, 45 km northwest of Tacna, Peru. Epizonal intrusions satellitic to the Caplina- Ataspaca pluton were emplaced 41 m.y. ago into limestones of the Lower Jurassic Pelado Formation along the northeast-trending Chucchuco fault system. Depths of emplacement ranged from 4.5 to 6.0 km....
Dyphylline is an analog of theophylline and the latter
is the most popular member of the methylxanthine family in
use for the treatment of asthma. Although dyphylline is
devoid of some problems associated with theophylline, a
reported short half-life has made it's clinical usefulness
limited. To avoid this problem a...
The purpose of this study was to determine if the preferences in
clothing fabrics and preferences in home furnishing fabrics are
similar or different in color, design size, and line. The
relationships of age, education, and training in color and design to
agreement of clothing fabrics and home furnishing fabrics...
The primary purpose of the study was to examine
how furniture arrangements in the lounges of institutions
for the elderly affect the social interaction
among the residents. Based on the furniture arrangements
that encourage social interaction, recommendations were
made for the placement of furniture in the lounges of
institutions for...
The purpose of this research was to evaluate the
effectiveness of two smoking cessation programs -- one
group and one self-help -- which were developed and are
currently employed by the American Cancer Society.
The research was conducted in a work setting, and
all subjects were employees of the State...
