We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

In the last few decades, a lot of studies have been conducted to study about the quality of stormwater runoff from various sites and conditions. Highways, residential areas, and commercial sites are the focus of most of these studies while limited studies have done examination of stormwater from Maintenance and...

The Chloroflexi CL500-11 clade contributes a large proportion of the bacterial biomass in the oxygenated hypolimnia of deep lakes worldwide, including the world's largest freshwater system, the Laurentian Great Lakes. Traits that allow CL500-11 to thrive and its biogeochemical role in these environments are currently unknown. Here, we found that...

BACKGROUND: Patients receiving hospice or palliative care often receive antimicrobial therapy; however the effectiveness
of antimicrobial therapy for symptom management in these patients is unknown.
OBJECTIVE: The study’s objective was to systematically review and summarize existing data on the prevalence and
effectiveness of antimicrobial therapy to improve symptom burden among...
Biochar is a highly porous, carbon-rich residue produced by thermochemical conversion (pyrolysis) of plant biomass and carbonaceous organic materials under oxygen-controlled conditions. Chars produced by this process tend to have high ion-exchange capacities and, when added to soil, increase retention of water and nutrients and improve soil aggregation, porosity, and...
Conventional soil maps represent a valuable source of information about soil
characteristics, however they are subjective, very expensive, and time-consuming to
prepare. Also, they do not include explicit information about the conceptual mental
model used in developing them nor information about their accuracy, in addition to the
error associated with...
A method was developed for the measurement of 19 parent PAHs (PAHs) and 34 hydroxylated
PAHs (OH-PAHs) in urine and personal air samples of particulate matter less than 2.5 um in
diameter (PM[subscript 2.5]) using GC-MS and validated using NIST SRM 3672 (Organic Contaminants in
Smoker’s Urine) and SRM 3673...
