The existence of a “digital divide,” or inequalities of access to digital technologies among different American subpopulations, has been hotly debated and contested since the National Telecommunications and Information Administration first popularized the phrase in 1995. The purpose of this thesis is to critically examine the dominant discourses around the...
Researching what I believe to be exclusionary practices in higher education against
African Americans has compelled me to approach this subject, in part, historically.
Although I realize that a historical chronology of any subject is often deceptive, as with
any writer, I am tempted to interpret events to fit my...
Soil bulk density and disturbance were measured before and after a commercial
thinning of 3 0-50 year-old Douglas-fir using a cut-to-length (CTL) and a skyline system
on the Willamette National Forest in the Oregon Cascades. A dual-probe nuclear
densimeter was used to measure bulk density at four and eight inches....
There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake soluble metal oxides from cell culture medium, and incorporate them into the micro- and nano-structure of their amorphous silica cell walls, called...
In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...
The turbulent interchange of matter between parallel adjacent
subchannels in a simulated rod bundle for single phase flow was investigated
to determine the effects of mass flow rate and rod spacing.
The simulated rod bundle was made by placing six 1-inch diameter
rods in a square-square array. The overall test...
The application of the personal computer in the area of real-time process control
is investigated. Background information is provided regarding factory automation and
process control. The current use of the PC in the factory for data acquisition is
presented along with an explanation of the advantages and disadvantages associated
with...
The genus Lopidea Uhler is revised for America north of
Mexico. The relationship of Lopidea to other orthotyline
genera is discussed and it is proposed that the genus
Ilnacora Reuter is the sister group of Lopidea.
Forty-eight species of Lopidea are recognized in North
America, one of which is described...
