In this paper, we discuss two possible modifications to a numerical solution method for a model of microbiologically induced calcite precipitation (MICP). MICP provides a means to seal cracks in the surfaces of geological structures. From a mathematical and computational point of view MICP has very interesting features which make...
The heroine of this fantasy novel is Alina who lives in a medieval-like time and place. The day before her 20th birthday, in an impetuous moment, she breaks a local superstition by standing in a sunbeam. This allows a fairy to kidnap her and take her to the fairy castle...
Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...
The Oregon Department of Education requires children to receive vision screening before entering elementary school, but does not require follow-up with an eye care professional after a failed screening. Whether such preventative vision care is effective at detecting children with vision problems was investigated through research from the American Optometric...
By identifying the relationships between abundance and metabolic activity in a bacterial community, we advance our knowledge of the marine carbon cycle. In the present study, our goal was to examine the role of protist grazing on the metabolic activity of γ- Proteobacteria in the upwelling system off the Oregon...

Unpublished female authors of American short fiction face many prejudices in fiction publishing, submission, and reviewing. These prejudices stem from the writer’s position in a gender-unequal society. Feminist fiction provides dimensional, diverse female characters in relationships where previous fiction had offered only stereotypes whose role was to support and reflect...
Historically, the difficulty of obtaining pure cultures of abundant marine
microbial plankton has an obstacle to reconstructing the underlying
mechanisms of biogeochemistry in the ocean. While a number of dominant
marine species from the ocean surface have been cultured, the dominant
microbial plankton of the dark ocean proved far more...
Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...
