Water fluoridation is considered one of the top ten greatest health achievements of the twentieth century due to its effectiveness in reducing the prevalence of dental caries. However, despite extensive research on the subject, there is little information currently available about how the constituents of drinking water affect the uptake...
Childhood tooth decay is a prevalent and concerning public health issue that is often misunderstood or dismissed. In Oregon specifically, over 50% of children have experienced at least one instance of tooth decay and these rates are even higher for marginalized communities such as children living in poverty, children of...

We consider development of sand ripples in shallow water flows which do not reach an equilibrium height but have a time-varying ripple height that slowly reaches a maximum value and then is quickly destroyed by the fluid. A simple scenario to explain the time periodic behavior of the sand ripples...
Platinum and palladium surfaces are utilized as catalytic surfaces in the chemical industry. Understanding how hydrogen atoms interact with the metal surfaces will allow for further advancement in this area. Specifically, the interaction of hydrogen on the surface and subsurface of these metals was investigated using density functional theory calculations...
The ferlin protein family regulates membrane trafficking events for a wide range of cellular and physiological processes in eukaryotic organisms. Structurally, ferlins are distinguished by containing five to seven C2 domains with a single-pass transmembrane domain at the C-terminus. In mammals, there are 6 ferlin genes, including Fer1L6, which confer...
Acute myeloid leukemia (AML) is a blood malignancy characterized by a differentiation and proliferation defect of myeloid progenitors leading to accumulation of myeloid blasts. It is one of the most common leukemias in adults. Trametinib (Mekinist) is a small molecule inhibitor that targets MEK1 (MAP2K1) and MEK2 (MAPK2K2). It has...
Our experiments aimed to investigate responses of the marine cyanobacteria Prochlorococcus and Synechococcus to toxic arsenic species, such as arsenate, and to understand cellular mechanisms that contribute to arsenic tolerance. We used two strains of Prochlorococcus, a high-light adapted MED4 and low-light adapted MIT9313, both axenic, for cultivation experiments. For...
Rising CO₂ concentrations in the atmosphere (396 ppmv as of April 2012)
increase the effect of global warming and climate change. CO₂ sequestration has become
a potential method to mitigate climate change. This study focuses on capillary/residual
trapping as a form of geologic CO₂ sequestration. Capillary/residual trapping occurs
when supercritical...
This study investigated learning in three engineering student clubs at a large public university. This included a small-sized chemical reaction car competition, a large-sized formula racing team, and an international humanitarian engineering club. Research methods included observations of work sessions (N=27) and semi-structured interviews (N=19). Using Cultural Historical Activity Theory...
YouTube is a free video watching and uploading site that allows endorsing and
sharing of videos. Youth and adolescents as top viewers of YouTube may be exposed to
images and messages on tobacco, marijuana and alcohol use behaviors.
The research project entailed deriving a list of songs from the 2014...
