Nitroaromatic compounds have important chemical applications and can be found in nature as pollution sources. Synthetic nitroaromatic compounds have been used in a variety of materials including explosives, pharmaceuticals, dyes, plastics, and pesticides. These compounds can find their way into the environment through normal or improper disposal methods.
Poly-aromatic compounds...

This report was prepared by students as part of a university course requirement. While considerable effort has been put into the project, it is not the work of licensed engineers and has not undergone the extensive verification that is common in the profession. The information, data, conclusions, and content...
A countercurrent, liquid-solids contactor was constructed,
operated and evaluated for a continuous ion-exchange operation.
The exchange of cupric and sodium ions between aqueous solutions
and Dowex 50W-X8 ion exchange resin was studied.
The countercurrent contactor consisted of two, three-inch
diameter columns with active sections ranging from one to four feet...
A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...
The subsurface microbial biosphere in the igneous oceanic crust has implications for global geochemical cycling, early life on Earth, and the search for life on Mars. Microscopic evidence of a subsurface microbial ecosystem includes biotic alteration textures associated with basaltic glass. The exact conditions in the basaltic layer that make...
Intensification of livestock operations has enhanced the problem
of animal waste disposal. Since high application rates of the
waste to soils would help elevate the problem, a study was established
to determine water quality as affected by applications of dairy
waste slurries to tiled and untiled soils.
Dairy cow waste...
A detail study of a Loss of Coolant Accident (LOCA) in a Pressurized
Water Reactor was conducted in order to estimate the consequences
of the accident using the computer simulation code EMERALD.
An effort was undertaken to modify the EMERALD code and to make
it operable on the OSU CYBER...
The photoelectron spectra of a series of halogenated
molecules have been investigated in the gas phase. Both
core-ionization energies and Auger kinetic energies were
measured to probe the nature of the interaction that holds
a core electron to the molecule.
It was found that satellite structure (shake) could be
used...
This study examined the singular and combined effects of a
progressive relaxation and biofeedback monitoring program upon Trait
Anxiety, Sports Competition Anxiety, blood pressure, heart rate, and
muscle tension as measured by EMG readings. The programs were
administered over a six-week sequence, with pre-measures utilizing
the Spielberger Trait Anxiety measure,...
