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...
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...
Instrumental and radiochemical neutron activation analyses supported by electron microprobe mineral analyses (Paul Warren, University of New Mexico) and petrographic observations are presented for approximately forty individual clasts separated from the Kapoeta howardite. These clasts are classified into eucritic, cumulate-like, mafic (plagioclase ± olivine-bearing pyroxenites), pyroxenite, polymict and/or metal-rich and...
Major and minor minerals have been separated from
three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin),
and Leedey). Olivine, hypersthene, diopside, feldspar,
troilite, chromite, phosphate minerals, and metallic
minerals were analyzed for major, minor and trace elements
using instrumental neutron activation analysis and radiochemical
neutron activation analysis techniques. Concentrations
df the...
Few discoveries of any importance have been the result of a moment's happy coincidence; rather have they been the fruit of many hours of tedious thought and experiment. This is especially true in the realm of organic chemistry. Here, where progress is made only by the most painstaking experimentation, extensive...
Studies were undertaken to determine the extent and rate of
binding of Hg-203 labeled phenylmercuric acetate and mercuric ace
tate in rat kidney and liver slices and their subcellular fractions
after 37°C incubation of the slices in Krebs-Ringer -phosphate solutions
containing the mercurials at 10⁻⁴ molar. A fast and parallel...
A continuous amperometric monitor for aqueous sulfite solutions
has been developed employing the electro-oxidation of sulfur (IV)
in 0. 1 M sulfuric acid at a glassy carbon test electrode. The monitor
employs a hydrodynamic flow cell, in which the solution stream
enters the cell through an orifice impinging on the...
The primary focus of this work is on examining structure-property relationships of interest for high-power nonlinear optical and laser crystals. An intuitive and simply illustrated method for assessing the nonlinear optical potential of structurally characterized noncentrosymmetric materials is introduced. This method is applied to materials including common quartz and tourmaline...
The concentration of chlorophyll in natural bodies of water is
commonly determined as a means to rapidly estimate the phytoplankton
biomass. The literature gives numerous warnings, however, as to the
problems involved with accurately determining chlorophyll
concentrations. The author's work at Crater Lake, Oregon enticed him
to explore critically the...
