More that just magnificent views of atoms and
molecules, Scanning Tunneling Microscopy, STM, images have
the potential to answer some fundamental questions relating
to surface molecular dynamics and bonding characteristics of
localized species versus more common analytical tools that
provide average of bulk sample information. A special
feature of the...
The free amino acid content of the intracellular pools in higher
marine fungi was determined by thin-layer and gas-liquid chromatography.
The organisms investigated include:
Ascomycetes; Nais inornata, Leptosphaeria oraemaris, Corollospora
maritima, Haligena elaterophora, Halosphaeria mediosetigera, Halosphaeria
appendiculata, Halosphaeria quadriremis, Lignincola Laervis
and Remispora hamata, and Fungi Imperfecti; Zalerion maritimum and...
Achlys triphylla, a member of a medicinally active family
containing alkaloids, was examined phytochemically to determine its
possible value as a source of medicinal agents.
Pharmacological testing of the crude ethanol extract exhibited
a competitive inhibition of acetylcholine and histamine. Purification
of alkaloid 'A' from the crude ethanol extract and...
Neurons in the abdominal ganglion of the marine mollusk,
Aplysia californica , appear to respond directly to changes in
blood flow and oxygen tension within the ganglion. When circulation
through the ganglion is reduced, the spontaneous activity of some
identifiable neurons are excited while others are inhibited. Many of
the...
School systems have an important responsibility to continuously
examine and review their educational programs to determine if the
programs satisfy the needs of the youth they serve. Systematically
collected data derived from former and present students can enable
the school system to appraise its effectiveness in fulfilling the aim
it...
Red Light Ladies presents a perspective on prostitution in North America, within the context of the western mining frontier. A biographical profile of the frontier
prostitutor is presented, along with an archaeological model of settlement patterns and material culture. Settlement patterns and demographic changes in the prostitutor
population are hypothetically...
Mean annual runoff to precipitation (R/P) ratios were generated for 966 watersheds within the contiguous United States. The watersheds were plotted using Arc View GIS and used as part of an overlay analysis with Level 1 U.S. ecoregions. The ratios were statistically evaluated to determine anomalous R/P conditions within the...
Five genotypes from California (Ventana, Caniarosa, San Miguel, 13G97, and Venice) and Oregon (Totem, Puget Reliance, Puget Summer, Hood and Independence) were evaluated for quality. The volatile compounds were analyzed using head space solid phase micro extraction-gas chromatography-flame ionization detection (GGFID) and gas chromatography-mass spectrometry (GC-MS). Odor activity values of...
