Andesitic and rhyolitic magmatism was active during the mid-
Tertiary (Early Miocene) of the Ash Peak area, southeastern Arizona.
Andesitic magmas of similar composition both preceded and followed the
low- and high-silica rhyolitic magmas. The changes from andesitic to
rhyolitic and back to andesitic volcanism is postulated to be the...
Previous investigations have shown that exposure to DDT results
in increased activity in soluble and microsomal enzyme in insects.
These responses in DDT-resistant Triatoma infestans
nymphs and in adults of DDT-resistant Musca domestica (the common
house fly) are accompanied by increased RNA and protein synthesis.
The phenomenon has been termed...
Narratives are central to communication and the human experience. For a computer system to understand a narrative, it must be able to identify the key facts or plot elements that describe what happened or how the world has changed. These element are called events;establishing a document’s events and the relationships...
The collapse of the I-35W Bridge in Minneapolis, MN in 2007 prompted an investigation into the design and inspection of the steel truss bridges. Further investigation into the collapse revealed that a gusset plate experienced sway buckling, causing the bridge failure. This bridge failure motivated research into the analysis and...
We conducted a 3-year study of helminth parasites to assess their effect on the lesser prairie-chicken Tympanuchus pallidicinctus. Helminth parasites were found in most of the examined wild prairie chicken carcasses: 95% had eye worm Oxyspirura petrowi, 92% had stomach worm Tetrameres sp., and 59% had caecal worm Subulura sp....
This report is concerned with environmental and animal internal temperatures in the intertidal zone at low tide. Daily sea surface temperatures at Agate Beach, Ore., are compared to weekly measurements made near-by. Greater range and fluctuations are revealed by daily measurements. Data are provided on animal internal temperatures at low...
A new class of enclosed path gas analyzers suitable for eddy covariance applications combines the advantages
of traditional closed-path systems (small density corrections, good performance in poor weather)
and open-path systems (good spectral response, low power requirements), and permits estimates of
instantaneous gas mixing ratio. Here, the extent to which...
Authors listed on this Accepted Manuscript vary slightly from those listed on the Version of Record. Harold L. Gibson is an additional author on the published version.
Capillary pressure-saturation data obtained for unconsolidated porous media with different liquids are examined to investigate the effects of clay-liquid interactions on liquid retention. Liquid retention functions are assumed to reflect the effective pore-size distributions. The hydraulic variables, capillary pressure and saturation, are transformed to account for changes in liquid retention...
A simple, fast liquid-liquid extraction method was developed for studying hexahydro-1,3,5-trinitro-1,3,5 triazine (RDX) biodegradation using small sample volumes. The method was tested
in vitro with anaerobic incubations of RDX with whole rumen fluid (WRF) and a commercial S.
acetigenes strain in methanogenic media for RDX. Additionally, validation experiments were
conducted...
