The role of the conceptus and ovarian hormones in regulating ovine uterine vasoconstriction was investigated. The uterine artery ipsilateral to the ovary bearing the corpus luteum in ten nonpregnant and eight pregnant ewes was utilized in two experiments. Arteries of nonpregnant and pregnant ewes were removed at necropsy on day...
The mechanism(s) involved with intrauterine migration of the porcine embryo was investigated. Twenty-four gilts on Days 6, 9 and 12 of gestation (Day 0 = 1st day of estrus) were utilized to examine the relationship between myometrial activity and intrauterine migration. On Day 2, embryos were flushed from one oviduct...
Rates of apparent net photosynthesis were measured on a sample
of Rocky Mountain Douglas-fir consisting of eleven one-year-old seedlings
from each of the thirteen different seed sources. Secondary
observations of needle length, needle weight, and needle number
were also obtained. A formula derived through step-wise multiple
regression of the secondary...
Net photosynthesis was measured for photosynthetic light efficiency and capacity on two-year-old plants from eight different seed sources in three measurement periods. The measurement periods corresponded to the physiological periods 1) prior to bud swelling, 2) after needle elongation, and 3) predormancy. Measurement period differences in both photosynthetic efficiency and...
Microscale reactors operate in sub millimeter space dimensions. Their small length scale enables process intensification of mass, heat and momentum transport that influence reaction rates. Hence it's possible to observe the true intrinsic reaction kinetics occurring for a set of reactions. In this work a novel microscale reactor for producing...
Articulate brachiopod communities sensitive to environmental factors, especially depth and distance from shore, are described from the upper Middle Devonian (upper Eifelian and Givetian; Cazenovia, Tioughnioga, and Taghanic stages of eastern North America) of eastern North America. The Subrensselandia, Cupularostrum, Mediospirifer, Tropidoleptus, Devonochonetes, Mucrospirifer, Atrypid-Strophodontid, Ambocoeliid, Pacificocoelia, Truncalosia, and Camarotoechia...
