This report describes the partial characterization of the first cultivable calicivirus isolated from a European rabbit (Oryctolagus cuniculus), named rabbit calicivirus Oryctolagus-1 and abbreviated RaCv Ory-1. RaCv Ory-1 was isolated from juvenile feeder rabbits displaying symptoms of diarrhea. Absence of neutralization by type specific neutralizing antibodies for 40 caliciviruses and...
Tn5 mutagenesis of apdA (for antibiotic production) and deletion of
gacA (for global antibiotic and cyanide) resulted in the same pleiotropic phenotype in
Pseudomonas fluorescens (i.e. production of an array of secondary metabolites
including the antibiotics pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol as
well as a tryptophan-side-chain oxidase, hydrogen cyanide, and an...
The goal of the project was to develop a functional prototype of an environmental risk assessment parameter database on the World-Wide Web. The ability to develop a consolidated environmental database has become possible due to the phenomenal growth of the Internet and the World-Wide Web over the past few years....
This study had two purposes: to determine solid waste management needs of residents and organizations of the San Xavier District Indian reservation near Tucson, Arizona; and to develop a solid waste management plan to be recommended to the San Xavier District Tribal Council.
A solid waste generation study compared the...
A study of deep levels of the emitter region of a
heterojunction bipolar transistor is investigated using deep
level transient spectroscopy (DLTS), deep level admittance
spectroscopy (DLAS), thermally stimulated capacitance
(TSCAP), and capacitance-voltage (C-V) profiling. The DX
center, with an activation energy of 0.45 eV, is the only
deep level...
This work is concerned with the modeling and analysis of lossy planar dielectric
optical waveguides. Loss mechanisms which affect propagation characteristics are
reviewed, and various representations of the propagation constant in the lossy case
are defined. Waveguide structures which are susceptable to absorption and/or to
leakage loss, in particular silicon-based...
The subduction of the oceanic spreading center at the Chile Triple Junction is marked by a substantial thermal perturbation
and marked changes in the hydrogeologic and aqueous geochemical regimes in the overthrust plate. Ridge subduction substantially
changes the fluid chemistry in the wedge through variably hydrating the oceanic basement, accretionary...
