Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...
Prediction of colloid transport in the subsurface is relevant to researchers in a variety of fields such as contaminant transport, wastewater treatment, and bioremediation. Investigations have traditionally relied on column studies whereby mechanistic inferences must be drawn on the basis of colloid behavior at the outlet. Over the past decade,...
One of the most common problems in wine production is the formation of hydrogen sulfide (H₂S) and other volatile sulfur compounds (VSCs), which can mask positive aromas at low concentrations and result in unpleasant aromas such as rotten egg, cabbage, garlic, and rubber at higher concentrations. Despite the large body...
Robots have the potential to protect health care workers, provide patient care, and ultimately save lives in infectious disease outbreaks. Nevertheless, infectious disease outbreak scenarios present unique technological and social challenges for robotics. This work explores what robots can and should do in the fight against infectious diseases. We present...
Non-suicidal self-injury (NSSI) is a significant issue among adolescents in the United States affecting 13% to 25% of young adults. In 2012, Arizona saw over 12,000 adolescents in emergency rooms due to self-injury. Approximately 50% to 85% of self-injuring adolescents will attempt suicide at least once during their lifetime. Adolescents...
Oregon is a state with great social and ecological diversity. Unfortunately however, Oregon's water-rich reputation is more rumor than reality. As with many Western states, Oregon struggles with water scarcity, especially during dry summer months. Recent efforts by the state to develop an integrated water resource strategy (IWRS) to manage...
This study examines the determinants of food consumption behaviors, such as purchasing less meat products, paying attention to how and where food is produced, and reducing food waste within the household. Food consumption is particularly important given that it can often comprise between 10% to 30% of the total household...
A product of global climate change, ocean acidification (OA) and other stressors increasingly put pressure on the economic, social, and cultural systems of Western U.S. coastal communities. In the face of increasing OA and local reports that OA is negatively impacting local communities’ socioeconomic structures, there is a clear need...
