Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...
In this work the electron energy distribution functions and the
anisotropic drift term of the velocity distribution functions in non-self-sustaining
(Townsend) discharges in argon were determined by
direct measurement for a range of E/N (electric field strength by
gas atom concentration) from 70 to 407 Townsends (Td). (One Td
A configuration-interaction determination of wave
functions has been made for the ²S and ²P states of lithium,
and for the ¹S and ³S states of the lithium ion.
Two 1s, one 2s, one 3s, and two 2p functions served as
starting functions for all four states. Results of the
Background Maternal blood total mercury (THg) is a biomarker for prenatal methylmercury (MeHg) exposure. Few studies have quantified both blood THg and MeHg during pregnancy, and few studies have reported longitudinal trends.
Objectives We analyzed blood THg and MeHg in a cohort of pregnant mothers in Charleston, South Carolina (n...
The Lawrence Memorial Grassland Preserve, located in
Wasco County, Oregon, exhibits a wide variety of soil mounds and
patterned ground features. The size, shape, and distribution of
several elements of this peculiar landscape were analyzed with a
detailed map, field observations, and statistical procedures.
Common soil mound shapes are circular,...
This thesis is the first third of a coming of age novel called i. In this
selection the central character, Bea Bouvier, prepares to see her estranged mother on
a cruise ship to the Bahamas. She hopes her parents will decide to reunite as a
family, though it becomes increasingly...
Water-source and ice-maker heat pumps share many
characteristics. However, each presents different
technical difficulties that have prevented them from being
used more widely. In a water-source heat pump a very
important consideration is to reduce water consumption,
while in an ice-maker heat pump a major concern is to
