A low velocity, low temperature beam of atoms is produced
from a two-dimensional magneto-optic trap known as an atomic
funnel. The funnel provides simultaneous spatial and velocity
compression of atoms and will provide a source for a three-grating
atomic interferometer. Rubidium atoms from an oven are slowed
by chirped cooling...
The ability of ovine endometrium incubated in vitro with
estradiol -17(3 to synthesize a specific induced protein (IP) was
studied. Endometrium from cycling, pregnant and ovariectomized
ewes was used.
Twelve ewes were allotted in equal numbers to be sacrificed on
days 0 (estrus), 3, 6, or 10 of the estrous...
Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...
I. The Effect of Artificial Photoperiod on Eating Behavior and Other
Behavioral Observations of Dairy Cows.
Twenty-eight cows were randomly assigned to a dairy photoperiod of
18 h light and 6 h darkness or to continuous light and observed 1 d each
month from December 1981 to February 19.82. Lighting...
In selecting the site for a new school, a school
district must consider four basic characteristics of a good
site: size, physical features, location and costs. The size
must be adequate to meet the state minimum standards and
provide for future expansion. The physical features, soil,
relief and slope should...
Infiltration, soil erosion, nitrogen loss and soil profile
characteristics were measured on 36 sites representing land occupied
by Artemisia tridentata ssp. tridentate, wyomingensis, and vaseyana.
Infiltration, soil erosion, and nitrogen loss were strongly correlated
but highly variable. Soil loss, but not infiltration or nitrogen
loss was significantly different between subspecies....
Indole-3-carbinol (I3C) inhibits chemically induced tumor
formation in rodents and rainbow trout. This study examines the
effect of I3C and its analog, indole-3-acetonitrile (I3N) on
xenobiotic-metabolizing enzyme systems. The modulation of these enzyme
systems have been shown to have significant effects on the
interaction of chemical carcinogens and cellular constituents....
