The amine extraction process is evaluated for pulse column
operation. A 0.1 M solution of Primene JM-T (a commercial mixture
of tertiary-alkyl primary amines) in a kerosene-base diluent is
the extractant for thorium feed in aqueous acidic sulfate solutions.
Equilibrium isotherms at room temperature are presented at
aqueous acidities of...
Members of the family Chlamydiae cause a wide range of diseases.
Chlamydia trachomatis and C. pneumoniae are most commonly associated with
human disease. C. psittaci and C. pecorum are largely animal pathogens, although
C. psittaci can cause pneumonia in the elderly and immunocompromised. A
vaccine against these pathogens is desirable,...
Hypoxia is a naturally occurring phenomenon that happens seasonally off the Oregon coast. As a consequence, there has been a great deal of research focused around analyzing the strength and duration of the hypoxic event during the summer season. This paper, however, takes an innovative approach by looking at the...

The Moderate or Intense Low-oxygen Dilution (MILD) combustion regime has received interest from the industrial furnace and gas turbine engine industries due to attractive properties of reduced NO[subscript x] emissions and high thermal efficiency. MILD combustion is characterized by low oxygen concentrations (i.e. 3%-9% by volume) and high reactant temperatures....
An experimental framework for investigation of the effects of Micro Pin Fin Arrays (MPFA) on the fuel oxidation efficiency of catalytic combustion is presented in this thesis. Complete combustion of the fuel is essential for operation at maximum efficiency and high standards of environmental cleanliness desired in existing microscale combustion...
¹³⁰ Sn and ¹²⁸Sn were separated from mixed fission products.
The decay of these isotopes were studied with Ge(Li),
LEPS, and plastic scintillator detector systems in single
and two parameter coincidence modes. The decay scheme constructed
for ¹²⁸Sn decay has levels at 0.0 (5+), 45.7 (4+),
77.8 (3+), 152.9 (2+),...
A study has been made of the kraft pulping properties of young Douglas-fir trees which were thinned from an experimental plantation. The purpose of the plantation study is to determine, whether two year old seedlings can be selected on the criteria of height and branch count for future desirable tree...
We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and
monitored their movements to determine daily, seasonal, and sexual differences in
behavior and home range attributes. We also collected information on nest attributes,
survival, and dispersal of the radiocollared voles. Individual voles were monitored for
