The temporal and spatial characteristics of a laser microprobe plume were investigated using the spectroscopic methods of emission, absorption and fluorescence. The plume was produced by rapid vaporization of a small quantity (1 μg) of a solid sample using a focussed pulsed dye laser (110 MW/cm²). For absorption and fluorescence...
The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...
Ninety basalt samples from eight locations in central Oregon
and one location in the Willamette Valley were analyzed for Si and Al.
Fourteen basaltic rock specimens (> 1 kg each) from four buttes in the
Willamette Valley were sampled and analyzed for Si, Al, Fe, Na, K,
Mn, Cr, Co,...

The concentration of seventeen elements in two species of fungus
which cause wheat bunt disease, Tilletia caries (DC.)Tul. (TS) and
Tilletia controversa Kiihn (DS), were determined by instrumental neutron
activation analysis in 37 TS spore samples, and 31 DS spore samples.
Aluminum was chosen as a soil contamination...
Nearly 100 chondrules were extracted from -8.6g of the
Mokoia (CV3) meteorite and have been analyzed by
sequential instrumental neutron activation analysis
(INAA). The resulting data were utilized in a
comprehensive statistical characterization of these
objects and, unlike similar investigations, virtually no
loss of relevant data was incurred due to...
Refractory inclusions from Kaba (CV3) chondrite were studied by
instrumental neutron activation analysis (INAA) and electron probe
microanalysis (EPMA). The inclusions observed cover a wide range of
chemical patterns, mineral assemblages and textures, indicating the
complexity of early solar nebular conditions. The elemental
abundances normalized by Cl chondritic abundances vary...
The Disney Princesses are some of the most beloved and well-recognized characters in animation across the globe. Most of these characters sing throughout their movie. This essay analyzes what I refer to as the “I Want” song of several Disney Princesses. It is divided into three sections, one for each...
