A significant number of Unreinforced Masonry (URM) buildings exist in the Pacific Northwest region of the United States of America that is a region of high seismicity, which could be subjected to both crustal and subduction zone earthquakes. The catastrophic and brittle failures associated with URM buildings in the past...
These first measurements of specific surface area (SSA)
of bulk samples of subsurface marine basalts were undertaken
to determine the potential area available for microbial
colonization. SSA ranged from 0.3 to 52 m2/g of basalt
with the lowest value coming from pillow basalt and the
highest value from breccia. The...
Lack of growing season precipitation and the temperate climate in north central Oregon
pose challenges to growing spring wheat crops. Phosphate and sulfate fertilization can
improve early growth of spring wheat in this region and soil testing aids in determining
rates of fertilization. In this study, anion exchange membranes (AEM)...

Bench scale column studies were used to examine the partitioning of microorganisms between groundwater
and a geologic medium and to examine the effect of hydrogeology (i.e., porous- versus fracture-flow) on
organism partitioning. Replicated columns were constructed with intact basalt core segments that contained
natural fractures and with the same basalt...
There is growing interest in the application of human-associated fecal source identification quantitative real-time PCR (qPCR) technologies for water quality management. The transition from a research tool to a standardized protocol requires a high degree of confidence in data quality across laboratories. Data quality is typically determined through a series...
Quantitative real-time PCR (qPCR) assays that target the human-associated HF183 bacterial cluster within members of the genus Bacteroides are among the most widely used methods for the characterization of human fecal pollution in ambient surface waters. In this study, we show that a current TaqMan HF183 qPCR assay (HF183/BFDrev) routinely...
Listeria monocytogenes is the third most deadly foodborne pathogen in the United States. The young and elderly, as well as pregnant and immunocompromised people are the population most susceptible to serious illness and death from listeriosis infections.
Unlike most foodborne pathogens, L. monocytogenes does not live a solely enteric lifestyle....
