BACKGROUND: In the prenatal period, women can have sustained contact with nurses and other clinicians, forming relationships that are likely to be health enhancing both for the woman and her unborn child. Yet first trimester care use in Oregon dropped noticeably over the past decade. In comparison with Washington State,...
The present work characterizes the time-space scales of variability and forcing dependencies of a unique 26 year record of daily to hourly shoreline data from a steep beach at Duck, North Carolina. Shoreline positions over a 1500 m alongshore span were estimated using a new algorithm called ASLIM based on...
Chordomas are uncommon neoplasms arising from notochord remnants, most commonly
occurring in the axial skeleton. Extraskeletal soft tissue chordomas are rare primary tumors, and
primary intestinal chordomas have not been reported. Herein we report 24 cases of spontaneous
primary intestinal chordomas in zebrafish, as well as 9 spontaneous vertebral chordomas....
We examine cumulative changes in investor sentiment and find that these changes relate to extended periods of increasing overvaluation, followed by price corrections. The relation between sentiment and returns is path dependent — short-term increases in sentiment precede strong positive returns, while prolonged periods of increasing sentiment precede negative returns....
Groundwater–surface-water (GW-SW) interactions in streams are difficult to quantify because of heterogeneity in hydraulic and reactive processes across a range of spatial and temporal scales. The challenge of quantifying these interactions has led to the development of several techniques, from centimeter-scale probes to whole-system tracers, including chemical, thermal, and electrical...
This study demonstrated at the pilot-scale (50 kg) use of Douglas-fir forest harvest residue, an underutilized
forest biomass, for the production of high titer and high yield bioethanol using sulfite chemistry
without solid–liquor separation and detoxification. Sulfite Pretreatment to Overcome the Recalcitrance
of Lignocelluloses (SPORL) was directly applied to the...
Globodera spp. eggs go through a diapause, which remains dormant until favorable hatching conditions are reached. Because of the regulatory concerns with cyst nematodes, it is often only possible to rear eggs for research in the greenhouse. However, hatch is often lower for greenhouse-produced eggs than for eggs obtained from...
Groundnut ringspot virus (GRSV) and Tomato chlorotic spot virus
(TCSV) are two emerging tospoviruses in Florida. In a survey of the
southeastern United States, GRSV and TCSV were frequently detected in
solanaceous crops and weeds with tospovirus-like symptoms in south
Florida, and occurred sympatrically with Tomato spotted wilt virus (TSWV)...
Fertigation with liquid sources of nitrogen (N) fertilizers, including ammonium sulfate and urea, were compared with granular applications of the fertilizers in northern highbush blueberry (Vaccinium corymbosum L. ‘Bluecrop’) during the first 5 years of fruit production (2008–12). The planting was established in Apr. 2006 at a field site located...
Land-use change around protected areas limits their ability to conserve biodiversity by altering ecological processes such as natural hydrologic and disturbance regimes, facilitating species invasions, and interfering with dispersal of organisms. This paper informs USA National Wildlife Refuge System conservation planning by predicting future land-use change on lands within 25...
The 2013 Pacific Coast Action Plan on Climate and Energy signed by the Governors of California, Oregon and Washington and the Premier of British Columbia, launched a broadly announced public commitment to reduce greenhouse gas emissions through multiple strategies. Those strategies include the development and increased use of renewable energy...
Premise of research: A distinctive new species of osmundaceous fern, based on a permineralized trunk from
Lower Cretaceous deposits of Haida Gwaii (formerly the Queen Charlotte Islands) off the west coast of mainland
Canada, provides additional data for addressing the Mesozoic diversity and the overall pattern of phylogeny
for osmundaceous...
Over 5000 aircraft eddy-covariance measurements from four different aircraft in nine different experiments are used to develop a simple model for the friction velocity over the sea. Unlike the widely used Coupled Ocean–Atmosphere Response Experiment (COARE) bulk flux scheme, the simple model (i) does not use Monin–Obukhov similarity theory (MOST)...
The assessment of enzymatic activity on Atlantic horse mackerel (Trachurus trachurus) during frozen storage was carried out in samples pre-treated by high pressure processing (HPP) combinations of 150, 300 and 450 MPa with 0, 2.5 and 5 min holding time (untreated samples were used as controls). The activities of four...
AIM: C₄ photosynthesis is an adaptation that maintains efficient carbon assimilation in warm and low-CO₂ conditions. Due to the importance of C₄ grasses for carbon and surface energy fluxes numerous models have been proposed to describe their spatial distribution and forecast responses to climate change. These models often rely on...
The Oregon education system at both the K-12 and Postsecondary level is strained for resources, with funding at levels far below the national average. This is due, in large part, to the small percentage of state taxes that are used to fund education. Public support for additional revenue for schools...
Analysis and design optimization of enhanced swing, low power CMOS LC oscillators is presented. A phasor analysis based approach for determining the amplitude and phase noise of these oscillators is used. MOSFET operation in cut-off, linear and saturation regions is included. The calculated steady state output amplitude and phase noise...
A new nematode, Anomalomermis ephemerophagis n. g., n. sp. (Nematoda: Mermithidae) is described from the mayfly Ephemerella maculata Traver, 1934 (Ephermeroptera: Ephermerellidae) in California. The new species is characterized by 6 cephalic papillae and 4 additional disk papillae located on the head between the cephalic papillae and stoma. Additional diagnostic...
Building Information Modeling (BIM) provides automatic detection of design-related errors by issuing warning messages for potential problems related to model elements. However, if not properly managed, the otherwise useful warning feature of BIM can significantly reduce the speed of model processing and increase the size of models. As the first...
Autoinduction (AI), the response to self-produced chemical signals,
is widespread in the bacterial world. This process controls
vastly different target functions, such as luminescence, nutrient
acquisition, and biofilm formation, in different ways and integrates
additional environmental and physiological cues. This diversity
raises questions about unifying principles that underlie all
AI...
