Deepnec: A Novel Alignment-Free Tool For The Characterization Of Nitrification-Related Enzymes Using Deep Learning, A Step Towards Comprehensive Understanding Of The Nitrogen Cycle, Naveen Duhan
Student Research Symposium
Abstract: Nitrification is an important microbial two-step transformation in the global nitrogen cycle, as it is the only natural process that produces nitrate within a system. The functional annotation of nitrification-related enzymes has a broad range of applications in metagenomics, agriculture, industrial biotechnology, etc. The time and resources needed for determining the function of enzymes experimentally are restrictively costly. Therefore, an accurate genome-scale computational prediction of the nitrification-related enzymes has become much more important.In this study, we developed an alignment-free computational approach to determine the nitrification-related enzymes from the sequence itself. We propose deepNEC, a novel end-to-end feature selection and …

Pyseqrna: An Automated Python Package For Advanced Rna Sequencing Data Analysis And Annotation, Naveen Duhan
Student Research Symposium
Abstract: With the advent of Next-Generation Sequencing (NGS) technologies, numerous data is being generated every day, however, streamlined analysis remains a big hurdle to efficiently use the technology. A large number of algorithms, statistical methods, and software tools have been developed in recent years to perform the individual analysis steps of various NGS applications. Some NGS applications data analysis procedures are therefore very complex, requiring several program tools to be downloaded for their various processing steps. There is a significant room for the development of scalable computing environments that link the individual software components to automated workflows to efficiently and …
Translating -Omics Big Data: Comprehensive Understanding Of Host-Pathogen Interactions To Control Bacterial Blight In Alfalfa Using Computational Approaches, Raghav Kataria
Student Research Symposium
Plant infectious diseases are a major threat to the crops, owing to economic losses to the agriculture industry worldwide. Molecular interactions between the host and pathogen play a critical role in understanding the basis of pathogenesis. Majority of the Pseudomonas syringae strains are known to cause frost injury in plants, amongst which, P. syringae pv. syringae ALF3 is asserted to be a causal organism of bacterial stem blight in Medicago sativa (alfalfa). We elucidated the genome-scale host-pathogen interactions (HPIs) between alfalfa and P. syringae using two intense computational approaches: interolog (homology-based) and the domain-based method (based on 3D structure of …
Examining Urban Soil Quality And Contamination Along The Wasatch Front, Frank Oliver
Examining Urban Soil Quality And Contamination Along The Wasatch Front, Frank Oliver
Student Research Symposium
Urban soil contamination has become an increasingly prevalent concern within residential developments and the expansion of urban agriculture. The purpose of this study was to establish an urban soil survey along the Wasatch Front to examine the concentrations of common contaminants and general soil quality in urban farms and community gardens during 2020-2021. Areas of concern include 1) heavy metals: lead, arsenic, cadmium, and chromium, 2) organic contaminants- petroleum hydrocarbons, polycyclic aromatic hydrocarbons, and volatile organic carbon, 3) pH, 4) soil salinity, and 5) elevated macronutrient levels. Measured contaminant concentrations will be compared to EPA regional screening levels (RSL) along …

Is Mitigation Of Drought Stress By Zinc Oxide Nanoparticles Driven By A Nano-Specific Mechanism Or Mitigation Of Micronutrient Deficiency?, Justin Deakin
Student Research Symposium
It has been reported that zinc oxide (ZnO) nanoparticles (NPs) can promote drought tolerance in crops when used as soil amendments. However, many of these experiments were conducted in Zn-deficient growth media with no comparison to currently available Zn fertilization methods, making it unclear if the benefits from adding ZnO NPs were caused by a nano-specifc mechanism or simply by the mitigation of a micronutrient deficiency. A review of the literature shows that of 12 published experiments considering the effects of ZnO NPs on plant health, 5 out of 6 studies that did not include a comparison to currently available …

Faculty Publications
The Arctic faces multiple pressures including climate change, shifting demographics, human health risks, social justice imbalances, governance issues, and expanding resource extraction. A convergence of academic disciplines—such as natural and social sciences, engineering and technology, health and medicine—and international perspectives is required to meaningfully contribute to solving the challenges of Arctic peoples and ecosystems. However, successfully carrying out convergent, international research and education remains a challenge. Here, lessons from the planning phase of a convergence research project concerned with the health of Arctic waters developed by the Arctic Science IntegrAtion Quest (ASIAQ) are discussed. We discuss our perspective on the …

Nitrogen Use Efficiency And Soil Bioavailable Nitrogen In Corn Silage Production In A Semi-Arid Environment, Phearen Miller
Nitrogen Use Efficiency And Soil Bioavailable Nitrogen In Corn Silage Production In A Semi-Arid Environment, Phearen Miller
Student Research Symposium
As agriculture intensifies, the world faces a dual challenge of increasing food production while reducing impacts of excess reactive nitrogen (N) in the environment. A field study examining different N sources in corn silage under semi-arid conditions was conducted at the Greenville farm in northern Utah (41°45’ N, 1111°48’52 W) since 2012. The experimental design is a randomized complete block design with four blocks and four treatments: control (no nitrogen), low ammonium sulfate (AS 112 kg N/ha), high ammonium sulfate (AS 224 kg N/ha), and steer manure compost (224 kg total N/ha). We examined yield, nitrogen use efficiency (NUE), and …

Geology Faculty Publications and Presentations
In 2015, the Olympic Mountains contain 255 glaciers and perennial snowfields totaling 25.34 ± 0.27 km2, half of the area in 1900, and about 0.75 ± 0.19 km3 of ice. Since 1980, glaciers shrank at a rate of -0.59 km2 yr-1 during which 35 glaciers and 16 perennial snowfields disappeared. Area changes of Blue Glacier, the largest glacier in the study region, was a good proxy for glacier change of the entire region. A simple mass balance model of the glacier, based on monthly air temperature and precipitation, correlates with glacier area change. The mass …

International Journal of Speleology
The decay of bat guano deposits in caves produces mineral accumulations, mainly phosphates and secondary sulfates. Chameau Cave, Eastern Morocco, is located in the semi-arid Bni Snassen Mountains. It is composed of semi-active and dry passages, and is featured by strong condensation-corrosion on the walls, presence of fluvial sediments, and old corroded flowstones. Due to forced and convective airflow, the cave is generally very dry, with some damp sites related to condensation. Samples collected on the surface of different passages and along two sediment profiles yielded minerals related to bat guano decay. On recent or fresh guano, precursor minerals correspond …

The surfaces of airless bodies such as lunar and S-type asteroids typically become spectrally redder in visible to near-infrared reflectance with longer exposures to space weathering. However, some carbonaceous asteroids instead become spectrally bluer. Space weathering experiments on carbonaceous meteorites have provided some clues as to the space weathering products that could produce spectral bluing. We applied these experimental results to our Hapke radiative transfer model, with which we modeled spectral data from the OSIRIS-REx mission in order to determine whether these space weathering products—specifically, nanophase and microphase metallic iron, troilite, and magnetite—could explain the globally blue spectrum of the …

Application Of The Global Srtm And Aw3d30 Digital Elevation Models To Mapping Folds At Cave Sites, Mark J. Abolins, Albert E. Ogden
International Journal of Speleology
A novel method to map and quantitatively describe very gentle folds (limb dip <5o) at cratonic cave sites was evaluated at Snail Shell and Nanna Caves, central Tennessee, USA. Elevations from the global SRTM digital terrain model (DTM) were assigned to points on late Ordovician geologic contacts, and the elevations of the points were used to interpolate 28 m cell size natural neighbor digital elevation models (DEM’s) of the contacts. The global Forest Canopy Height Dataset was subtracted from the global 28 m cell size AW3D30 digital surface model (DSM) to create a DTM, and that DTM was applied …
