Adult male guinea pigs were maintained on four dietary regimens
for a period of 8 weeks. The basic diet consisted of powdered guinea
pig chow with 10% coconut oil. The three experimental groups
received the basic diet with additions of either 1% lecithin, 0.25%
cholesterol, or 0.25% cholesterol plus 1%...
Soil samples from the Mazama tephra deposit were collected
from the AC and C2 horizons at five different locations along the axis
of the main depositional lobe. The clay fraction from the samples
was recovered and studied by means of chemical, x-ray, DTA and
electron microscopy methods in order to...
The problem of this study was to determine whether graduate students
in education (the experimentals) participating in a counseling
practicum would demonstrate a change in self-actualization which would
be significantly different when compared with other graduate students
in education (the comparisons) who were not participating in the above
program. The...
The problem of the study was to determine whether university students
enrolled in a pre-service teacher training course and exposed to a group
counseling procedure having as its major emphasis education in the affective
domain could demonstrate a significant change in self-actualization
when compared with similarly enrolled students who had...
Low concentrations of hexachlorophene (HCP) inhibit a number of pyridine nucleotide-linked dehydrogenase enzymes. The I₅₀ HCP concentrations were 105 μM for pig heart isocitrate dehydrogenase (ICD), 65 μM for horse liver alcohol dehydrogenase, 39 μM for torula yeast glucose-6-phosphate dehydrogenase (G6PD), 6.0 μM for beef heart malate dehydrogenase, and 1.6...
C-methyltransferase
(HIOMT) in chinook salmon (Oncorhynchus
tshawytscha). Various body tissues, as well as several
morphological brain divisions were tested for the presence
of HIOMT. Activity was found in the retina, the dorsal
portion of the diencephalon, and in the pineal gland of
chinook. However, the activity was significantly higher
in...
Descriptions and distributions are given of 28 species of
Liparidae occurring or possibly occurring below 200 m between San
Francisco and northern Vancouver Island, with keys for their identifications.
Nine genera are included: Careproctus, Elassodiscus,
Lipariscus, Nectoliparis, Rhinoliparis, Acantholiparis, Paraliparis,
and two new genera are described, Odontoliparis and Osteodiscus.
Eight...
Four experimental groups were designed to examine the effects of a "greens" dietary supplement (wheat clippings), as well as individual versus group-housing, on the adrenal and reproductive physiology of Microtus canicaudus. Organ culture of adrenal glands, thin-layer chromatography, and fluorescence analysis of steroid-containing medium were used to quantitatively assess adrenal...
In order to quantitatively examine the crustal structure of the
Panama Basin without the benefit of local seismic refraction data, the
following assumptions were made: (1) No significant lateral changes
in density take place below a depth of 50 km. (2) The densities of the
crustal layers are those of...
Root rot due to Armillariella mellea (Vahl. ex Fr.)
Karst. is unusually severe in ponderosa pine near Glenwood,
Washington. Isolate relations, clonal variability, vegetation
patterns, and climate were examined in relation to
severity of disease in this area.
Ninety-one isolates from 70 infection centers were
examined. Pairings of neighboring isolates...
This thesis research consists of an investigation of the human
influences on wildlife in Belize. The study was accomplished by the
collection and analysis of data with respect to land use, habitat
characteristics, and wildlife status in Belize. Requirements and
status of many species are tabulated in order to give...
Gas mixing is studied in fluidized beds of large particles. The
bed is 0. 483 m by 0. 127 m (19 in. by 5 in. ) in cross section and has
transparent plexiglass panels on the front and back. A tube matrix
made of twenty-seven 50.8 mm (2 in.) diameter...
A detailed study of iron concentrations measured by the reducible,
reactive ferrous, and extractable methods was conducted in Auke Bay,
Alaska during June 1973 and in Hood Canal, Washington during October
1973 and April 1974. The concentrations by each method were generally
highest at the bottom and decreased towards the...
Almond growth has recently been initiated in Mexico in the effort to realize commercial production. This research paper is an evaluation of the physical environment conditions which favor almond production and an attempt to apply them to Mexico. It is shown that areas in the Northwest and Central Plateau are...
A study, using greenhouse and laboratory experiments, was
made of Hemicycliophora similis from Bandon, Oregon to determine:
identity and morphometrics, time and development of a life cycle,
host plant preferences and optimum environmental conditions for
reproduction and pathogenicity.
Morphometric investigations revealed discrepancies between
the measurements of this nematode species and...
A radix 2n non-restoring division algorithm is described. The
algorithm is designed to be compatible with hardware multiprecision
multiplication methods currectly used in high speed digital computers.
This enables the use of the same hardware, with only changes in
control logic, to be used to implement both multiplication and
division....
