A static-renewal, seven day test was developed and
utilized to study the effects of nutrition on the sensitivity
of Mysidopsis intii Holmquist to zinc. It was found that
juvenile growth was the most reliable and sensitive endpoint
that could also reflect the subtle effects of low zinc
concentrations and diet...
Because of the potential elevated-temperature applications
of high-purity vanadium in nuclear reactors an
investigation was conducted to determine the effects of
nuclear irradiation upon the properties of the pure metal.
The results of this investigation indicated that the effects
caused by irradiation, increased strength and hardness and
decreased ductility, could...
An investigation of the effects of temperature and of zinc on
development of tobacco mosaic virus (TMV) in resistant and susceptible
varieties of tomatoes was conducted under greenhouse conditions.
The study included two experiments, one run during late winter and
early spring, and the other during late spring and summer,...
This dissertation is an exploration of the material response to Terahertz (THz) radiation. Specifically we will explore the ultrafast electron dynamics in the nonperturbative regime in semiconductors that have been patterned with nanoantenna arrays using broadband, high intensity, THz radiation. Three main semiconductor materials will be studied in this work....
Metals are a persistent form of freshwater pollution and have been shown to bioaccumulate in aquatic macroinvertebrates through direct contact with contaminated water, sediments, and through consumption of contaminated organisms. This research explored the longitudinal bioaccumulation patterns of 5 common trace metals (Cr, Cu, Zn, Cd, and Pb) in the...
This report is one of a series issued in cooperation with the ANC-23 Panel on Composite Construction for Flight Vehicles of the Departments of the Air Force, Navy, and Commerce.
Two framework oxide materials of the MO₃ network type have been synthesized and structurally characterized by synchrotron and X-ray powder diffraction and the Rietveld method in the temperature range 25~500 K. The results show one of them to be a low thermal expansion material. Theoretical studies of negative thermal expansion...
This report presents the results of analyses of several
hundred Pacific Hake, Merluccius productus, for zinc (Zn), zinc-65
(65Zn), cadmium (Cd), and mercury (Hg). The fish were collected
off the coast of the western United States in 1969-1972. In
addition, some data from mercury analyses of fresh and seawater
samples...
In this study the impact of episodic events on levels of bioavailable trace metals Zn,
Cu, Cr, Cd, Pb, and As (III) were determined for the lower Willamette River in Oregon.
In addition, a comparison among three alternative methods for estuary sampling was
conducted. Potential adverse human health risk associated...
Concentrations of selenium (Se), manganese (Mn), zinc (Zn), cadmium (Cd), lead (Pb) and arsenic (As) were measured in the water column, sediment and biota, in conjunction with selected physicochemical data, from representative wetland types at a mining site within Salt Lake County, Utah, USA. The selected field sites included Oolitic...
