During volcanic eruptions ascending magma undergoes decompression, resulting in a decrease of dissolved H2O. This creates unstable conditions for the hydrous mineral amphibole. As a result a reaction rim forms from anhydrous minerals such as pyroxene, plagioclase, and Fe-Ti oxides (Rutherford and Hill, 1993). There have been numerous studies done...
The Tam McArthur Rim is a volcanic center located within the Tumalo Volcanic Field (TVF), approximately 25 km west of Bend, OR. The rim comprises of shallowly dipping bedded sequences of intermediate and silicic flows with minor tephra interbedding capped by a rhyodacite dome. Glacial activity has exposed significant portions...
The origin of hornblendite and other mafic mineral-rich veins found in Cretaceous plutonic rocks from the Northern Cascades is currently not well known. This study seeks to investigate the possible relationship between host plutonic rocks and hornblendite and pyroxene-rich veins by comparing the chemical compositions and petrographic features between the...
As a major biological model for biomedical research, maintaining healthy
zebrafish (Danio rerio) is imperative for accurate and consistent lab results. This
retrospective study focuses on Pseudoloma neurophilia, a microsporidium, because it is
the most common pathogen found in laboratory zebrafish. An online database maintained
by the Zebrafish International Resource...
As the zebrafish (Danio rerio) becomes increasingly popular as a biomedical model for various laboratory studies, the need for efficient and accurate diagnostic assays for the pathogens that infect it has grown. The most common pathogen infecting laboratory zebrafish is Pseudoloma neurophilia, a microsporidium that has been known to cause...
Decades of experimental work has illustrated the high degree to which the partitioning of most elements is dependent on phase composition, temperature and pressure. In order to quantitatively describe clinopyroxene partitioning it is required to derive expressions using theoretical constraints calibrated with experimental data.
The experimental database available for such...
M. abscessus subsp. abscessus is a nontuberculous mycobacterium causing pulmonary infections in immunocompromised patients. The treatment of MAB infections is challenging due to its natural resistance to most antibiotics. To identify MAB genetic factors that are involved in mechanisms of the antibiotic tolerance, we screened the library of 2,000 gene...
Camelid health and parasitology experts disagree on what a “safe” level of internal parasitism is in camelids. The objective was to determine the levels of parasitism in show camelids (llamas and alpacas). The hypothesis was that fecal egg counts (FEC) in camelid would differ based upon geographic location, species (llama...
A rapidly expanding body of evidence suggests that relationships exist between the microbiome and vertebrate health and disease. The zebrafish is a frequently utilized model organism to support this claim. Specifically, its gut microbiome is an advantageous resource for the study of microbiome health and diversity. While it is an...
