Characterization Of Halophyte Rhizosphere Microbiomes At Great Salt Lake, Utah, Haley K. Nate
Characterization Of Halophyte Rhizosphere Microbiomes At Great Salt Lake, Utah, Haley K. Nate
Utah Space Grant Consortium
The saline soils comprising the shoreline of Great Salt Lake, Utah (GSL) provide a unique habitat for both halophytes (salt-tolerant plants) and the microorganisms that inhabit their rhizosphere. While plant diversity has been well documented at GSL, little is known about the microbial diversity in the rhizosphere. Here we present preliminary data characterizing the halophyte rhizosphere microbiome at two GSL locations; the more saline North Arm near the artwork, Robert Smithson's Spiral Jetty (SJ), and the less saline South Arm on Antelope Island (Al). The rhizosphere of several plants along the shoreline at both SJ and Al locations was sampled. …
Identification Of Haloarchaea In Gypsum From Great Salt Lake, Zhantao Du
Identification Of Haloarchaea In Gypsum From Great Salt Lake, Zhantao Du
Utah Space Grant Consortium
Gypsum (CaSO4·2H2O) is a common precipitate at Great Salt Lake (GSL). On Earth, gypsum is formed in hypersaline environments, in minerals left behind when water evaporates. In the Autumn, as the water cools, mineral precipitation is favored since solubility is lowered. In this process, newly formed gypsum will trap microorganisms in fluid and clay inclusions. This study is to cultivate haloarchaea preserved in gypsum, and identify the species using PCR technique.
Designing An Optimal Lighting Fixture For Extraterrestrial Crop Growth: Integrating Efficacy And Photobiology, Paul Kusuma
Designing An Optimal Lighting Fixture For Extraterrestrial Crop Growth: Integrating Efficacy And Photobiology, Paul Kusuma
Utah Space Grant Consortium
Extraterrestrial crop growth will require the development of technologies that provide photons to drive photosynthesis. Light-emitting diode (LED) technology is the likely technology of choice due to 1) its inherent flexibility, and 2) its high efficiency. Here we describe two important considerations for the optimization of this system: photon efficacy (μmol of photons produced per joule of input electrical energy) and spectral effects on plant growth and development. With these two considerations, we suggest the design of an LED fixture for extraterrestrial crop growth that contains a 5:10:55:30 ratio of blue, green, red, and far-red photons (respectively). This would be …
Connecting Land Cover To Benthic Cover Within The Watershed: Quantifying Impacts Of Terrigenous Sediment On Coral Reef Health And Morphology Using Remote Sensing And Machine Learning, L. Kalai Ellis
Utah Space Grant Consortium
Erosion, with associated sedimentation of reefs and loss of habitat for marine and coastal species, is one of the most pressing environmental challenges in Hawaii. Identifying hotspots of soil erosion guides management on land, but limited work has been done connecting land cover to coral reef health and morphology. Current reef survey methods overgeneralize the spatial variation of benthic cover and this has been reflected in incorrect Geographic Information System (GIS) layers of the reef. We propose a novel and more holistic approach to improve accuracy by connecting sedimentation from source to sink using Unmanned Aerial Vehicles (UAVs), Unmanned Surface …
Predicting Propofol-Induced Burst Suppression Using An Individualized Model-Based Approach Over Repeated Treatments, Jason C. Huang
Predicting Propofol-Induced Burst Suppression Using An Individualized Model-Based Approach Over Repeated Treatments, Jason C. Huang
Utah Space Grant Consortium
Our group is investigating the antidepressant effects of high-dose propofol, but dosing propofol to induce standardized changes in EEG activity (“burst suppression”) is challenging due to limited knowledge of each subject’s pharmacokinetics (PK) and pharmacodynamics (PD). In this paper, we approximated PK-PD models for propofol-induced burst suppression (PIBS), based on multiple subjects over repeated treatments. We then applied these models to predict BSR in each subject’s repeated treatment, then evaluate their predictive performances. We hypothesized that predicting BSR from a greater number of previous treatments would improve performance, but our current results are not conclusive enough to validate the hypothesis. …
