What’S Next After Industry Disruption By Cubesats? – Industry Disruption By Open Source, Anita Bernie, John Paffett
Small Satellite Conference
A decade ago, CubeSats featured almost exclusively in the academic domain only. The same can be said today for Open Source satellites.
In the same way that CubeSats and the associated development mindset started in the academic community and are now embraced by commercial, civil and defence communities, the goal of the Open Source Satellite Programme is to initiate a similar outcome for open source satellite mission architectures by developing a design that is freely available for all to use.
KISPE’s goal is to build a community of open-source contributors, collaborators and beneficiaries, including those from CubeSat and SmallSat teams …

Caspr: Autonomous Sensor Processing Experiment For Stp-H7, Seth Roffe, Theodore Schwarz, Thomas Cook, Noah Perryman, Justin Goodwill, Evan Gretok, Aidan Phillips, Mitchell Moran, Tyler Garrett, Alan George
Small Satellite Conference
As computing technologies improve, spacecraft sensors continue to increase in fidelity and resolution, their dataset sizes and data rates increasing concurrently. This increase in data saturates the capabilities of spacecraft-to-ground communications and necessitates the use of powerful onboard computers to process data as it is collected. The pursuit of onboard, autonomous sensor processing while remaining within the power and memory restrictions of embedded computing becomes vital to prevent the saturation of data downlink capabilities. This paper presents a new ISS research experiment to study and evaluate novel technologies in sensors, computers, and intelligent applications for SmallSat-based sensing with autonomous data …

Small Satellite Conference
The HyTI (Hyperspectral Thermal Imager) mission, funded by NASA’s Earth Science Technology Office InVEST (In-Space Validation of Earth Science Technologies) program, will demonstrate how high spectral and spatial long-wave infrared image data can be acquired from a 6U CubeSat platform. The mission will use a spatially modulated interferometric imaging technique to produce spectro-radiometrically calibrated image cubes, with 25 channels between 8-10.7 ųm, at 13 cm-1 resolution), at a ground sample distance of ~60 m. The HyTI performance model indicates narrow band NE△Ts of < 0.3 K. The small form factor of HyTI is made possible via the use of a no-moving-parts Fabry-Perot interferometer, and JPL’s cryogenically-cooled HOT-BIRD FPA technology. Launch is scheduled for no earlier than Fall 2021. The value of HyTI to Earth scientists will be demonstrated via on-board processing of the raw instrument data to generate L1 and L2 products, with a focus on rapid delivery of data regarding volcanic degassing, land surface temperature, and precision agriculture metrics.
In this presentation we will provide an overview of the HyTI measurement approach, the onboard data …

Characterization Of Chinese Hamster Ovary Cell Performance With Pentanoic Acid And N-Acetyl Cysteine Treatment, Joseph Camire
Characterization Of Chinese Hamster Ovary Cell Performance With Pentanoic Acid And N-Acetyl Cysteine Treatment, Joseph Camire
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
To improve the cost of producing protein therapeutics manufacturers can attempt to increase the amount of protein produced per unit volume. Some small fatty-acids have shown the ability to increase protein concentrations in some manufacturing systems. An example system is in the industrially important cell line derived from a Chinese Hamster Ovary (CHO). A drawback of adding these fatty-acids is they can increase the rate of cell death.
A potential way to minimize the cell death rate, caused by adding fatty-acids, is to also add additional anti-oxidants. Through a series of studies, we demonstrate production with different fatty-acids, butanoic acid …
Evaluation Of Enrichment And Identification Media For Isolation Of Common Bovine Salmonella Serotypes, Katie Irene Swanson
Evaluation Of Enrichment And Identification Media For Isolation Of Common Bovine Salmonella Serotypes, Katie Irene Swanson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Salmonellosis is an important cause of diarrhea in humans and animals, which can lead to death in severe cases. Rapid and efficient detection of Salmonella spp. is essential to limit the spread of disease. Many enrichment procedures have been described for the isolation of Salmonella, and often include variations on Rappaport-Vassiliadis medium, which is recommended by the Food and Drug Administration (FDA). The current procedures vary in incubation temperature, incubation time, and type of media used for identification of Salmonella. This project compared four procedures for enrichment and identification of common bovine Salmonella serotypes. We determined the best …
The Effects Of Gene Therapy In An Ovine Osteoarthritis Model, Crystal Collier
The Effects Of Gene Therapy In An Ovine Osteoarthritis Model, Crystal Collier
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Humans rely on the health of their joints for stability and mobility in daily life. In a normal, healthy functioning joint, complex processes maintain joint tissues, including remodeling, lubrication, and immune function among many other tasks. Osteoarthritis (OA) is the most common joint disorder in the U.S. It becomes most prevalent in adults 60+ years of age and causes decreased mobility, discomfort, and in some cases, excruciating pain. In the biological processes of osteoarthritis, the metalloproteinase enzymes responsible for the degeneration of cartilage are upregulated. The inhibitors of metalloproteinase activity are known as Tissue Inhibitor of Metalloproteinases (TIMPs), which keep …
Ecoacoustic Methods For Multi-Taxa Animal Surveys In The Amazon, Leandro A. Do Nascimento
Ecoacoustic Methods For Multi-Taxa Animal Surveys In The Amazon, Leandro A. Do Nascimento
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Tropical regions host most of the biodiversity found on Earth, but these species-rich areas are constantly threatened by human development and other disturbances that put this diversity of life forms at risk. To avoid extirpations of animal and plant species, scientists and managers rely on accurate monitoring techniques to retrieve information about population trends. This task is not easy, especially in the tropics, where there is often a lack of personnel to conduct surveys, a lack of funding, and the areas are so extensive that many countries need to be involved in monitoring (e.g., Amazon biome). For this reason, scientists …
Trisiloxane Surfactant Adjuvants In Pollen, Autumn Slade
Trisiloxane Surfactant Adjuvants In Pollen, Autumn Slade
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Chemicals are often added to agricultural pesticide mixes to help increase the efficiency of the field spray solution, and one of the main groups of chemicals used for this purpose are trisiloxane surfactants (TSSs). Normally TSSs are considered non-toxic, but recent studies have shown TSSs to have negative impacts on organisms like honey bees. Though TSSs have recently been found in environmental sources like water, pollen, and beeswax, little is known about how TSSs behave in the environment or affects active ingredients, like pesticides.
To help determine the environmental prevalence and fate of TSSs, several studies were performed. Pollen was …

A Brief Online Acceptance And Commitment Training For Enhancing Outcomes Of A Cultural Competence Intervention, Elizabeth Tish Hicks
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In an increasingly diverse and multicultural society, there is a pressing and practical need for interventions to help professionals improve their cultural competence. Cultural competence trainings that target psychological flexibility in addition to knowledge, awareness, and skills may produce more efficacious results. The current study will examined the utility of targeting psychological flexibility (the ability to maintain contact the present moment and current internal experiences and to choose contextually appropriate, values-consistent behaviors, regardless of what one’s internal experiences are) as a process to enhance the impact of a cultural competence intervention with an Acceptance and Commitment Training (ACT)-enhanced cultural competence …
Boron In The Pariette Wetlands, Uinta Basin, Ut, Palak Vasudeva
Boron In The Pariette Wetlands, Uinta Basin, Ut, Palak Vasudeva
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Boron is a naturally occurring mineral in shale and coal beds formed in marine environments, as found in the Uinta Basin. Mining activity and the application of excess irrigation water on agricultural lands in the Pariette watershed lead to mobilization of B via surface run off. Water quality monitoring records from 2006- 2009 reported violations of Utah B standard for irrigation water 43-100% of the time, for water flowing through the Pariette Wetlands. This study aims to determine B distribution in abiotic (water, sediments) and biotic samples (macroinvertebrates, aquatic vegetation, fish, bird eggs), and to establish correlations between B concentrations …
Effect Of Plant Derived Tannins On Nitrogen And Carbon Cycling In Pasture Soils, Kathryn A. Slebodnik
Effect Of Plant Derived Tannins On Nitrogen And Carbon Cycling In Pasture Soils, Kathryn A. Slebodnik
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Pasture-finished beef has become increasingly popular, but nitrogen losses from these pastures are of concern. Legumes containing condensed tannins such as birdsfoot trefoil (Lotus corniculatus) and sainfoin (Onobrychis viciifolia) may serve as environmentally and economically viable alternative forages in pasture finishing systems while reducing soil nitrogen loss. The goal of this project was to understand how tannin type and concentration affects soil nitrogen cycling both in the lab and the field. This thesis: 1) compared the physical, chemical, and biological characteristics of soil samples obtained from grazed grass and tannin and non-tannin containing legume pastures, 2) …
Novel Three-Dimensional Scaffold For Skeletal Muscle Tissue, Matthew H. Clegg
Novel Three-Dimensional Scaffold For Skeletal Muscle Tissue, Matthew H. Clegg
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cells are traditionally grown on a flat, plastic surface that has been optimized for cell attachment. While this is appropriate for growing and maintaining cells, this two-dimensional cell culture model is not an adequate representation of a three-dimensional body. Creating three-dimensional lab models is an important step to model diseases and damage to the skeletal muscle system.
To create this three-dimensional environment, a plastic frame was designed to support silkworm fibers. Skeletal muscle cells were then grown along the silkworm fibers and the growth of these cells in a three-dimensional environment was compared to cells grown on a flat, two-dimensional …
Reusable Light-Activated Antimicrobial Materials Prepared With Food Ingredients, Andrew T. Gagon
Reusable Light-Activated Antimicrobial Materials Prepared With Food Ingredients, Andrew T. Gagon
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Microbial contamination and proliferation in food processing, distribution and storage continues to be a real risk in spite the wide variety of food processing and preservation techniques available. Some of these techniques (such as heat treatments and the use of chemical preservatives) may require substantial amounts of energy and their effects in the general population and the environment may be harmful. This has generated an interest over alternative methods of food preservation. The use of reusable light-activated materials may represent an effective approach. In this study, a polypropylene plastic was modified with either zein, which is found in corn, or …
Cross-Boundary Stewardship For Wetland Integrity And Resilience In The Greater Rocky Mountain National Park Ecosystem, Meghan K. Tait
Cross-Boundary Stewardship For Wetland Integrity And Resilience In The Greater Rocky Mountain National Park Ecosystem, Meghan K. Tait
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Approximately half of the wetlands in Rocky Mountain National Park (RMNP) are degraded due to human disturbances that often occur beyond park boundaries. Like most protected areas, RMNP is part of a larger ecosystem with critical connections to surrounding lands. Therefore, more effective stewardship of wetlands within RMNP is likely to be achieved through cross-boundary cooperative efforts. Through interviews with wetland stewardship agencies and organizations and an analysis of their wetland plans and policies, barriers and opportunities for cross-boundary stewardship were identified, as well as common structures used to facilitate work across boundaries. Wetlands outside of RMNP are experiencing similar …
Influence Of Forage Diversity And Condensed Tannins On Livestock Foraging Behavior, Production And Environmental Impact, Sebastian P. Lagrange
Influence Of Forage Diversity And Condensed Tannins On Livestock Foraging Behavior, Production And Environmental Impact, Sebastian P. Lagrange
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Eating a combination of forages with different chemistries (i.e., nutrients, beneficial compounds such as tannins) may enhance ruminant nutrition and reduce environmental impacts relative to eating single forages. I explored the influence of offering sheep and cattle all possible combinations of tanniferous (i.e., plants with tannins; birdsfoot trefoil, sainfoin) and non-tanniferous legumes (i.e., plants without tannins; alfalfa) or their monocultures on animal performance, behavior, and methane and nitrogen (N) emissions. Offering choices among these legumes to penned sheep improved intake and diet digestibility relative to feeding monocultures. Mixtures selected by sheep were better digested than mixtures containing equal parts of …
Soil Health Assessment On Arid Rangeland Soils Impacted By Oil And Gas Exploration, Development, And Extraction, Justin Allred
Soil Health Assessment On Arid Rangeland Soils Impacted By Oil And Gas Exploration, Development, And Extraction, Justin Allred
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Oil and gas well pad reclamation in arid environments such as in the Uinta Basin of Utah, presents unique challenges, including remote locations, limited water, and elevated soil salinity and sodicity. Successfully reclaimed Plugged and Abandoned (P&A) well pads should resemble the surrounding rangeland once fully reclaimed. Revegetation of native species is the primary indicator of successful reclamation, but the lack of water makes it challenging to re-seed native plants, while trying to prevent the encroachment of invasive plant species such as Bromus tectorum (cheatgrass), Salsola tragus (Russian thistle), and Halogeton glomeratus (halogeton). Could successful reclamation be reflective of good …
Visual Saliency Estimation And Its Applications, Fei Xu
Visual Saliency Estimation And Its Applications, Fei Xu
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The human visual system can automatically emphasize some parts of the image and ignore the other parts when seeing an image or a scene. Visual Saliency Estimation (VSE) aims to imitate this functionality of the human visual system to estimate the degree of human attention attracted by different image regions and locate the salient object. The study of VSE will help us explore the way human visual systems extract objects from an image. It has wide applications, such as robot navigation, video surveillance, object tracking, self-driving, etc.
The current VSE approaches on natural images models generic visual stimuli based on …
Improving Our Ability To Estimate Vital Rates Of Endangered Fishes On The San Juan River Using Novel Applications Of Pit-Tag Technology, J. Benjamin Stout
Improving Our Ability To Estimate Vital Rates Of Endangered Fishes On The San Juan River Using Novel Applications Of Pit-Tag Technology, J. Benjamin Stout
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Estimating demographic parameters, such as survival and abundance, with accuracy and precision is vital for detecting trends in populations and assessing the effectiveness of management actions. In most cases, a lack of capture data make estimating parameters very challenging. The use of new technologies to increase the amount of remotely collected data is increasing, but brings new limitations and analytical issues to be resolved. One of those new technologies is the use of a mobile floating PIT-tag antenna to detect PIT-tagged fish. The issue that arises with this technology is determination of the status of detected tags (i.e., live fish …
Comparative Analysis Of Small Non-Coding Rna And Messenger Rna Expression In Somatic Cell Nuclear Transfer And In Vitro-Fertilized Bovine Embryos During Early Development Through The Maternal-To-Embryonic Transition, Jocelyn Marie Cuthbert
Comparative Analysis Of Small Non-Coding Rna And Messenger Rna Expression In Somatic Cell Nuclear Transfer And In Vitro-Fertilized Bovine Embryos During Early Development Through The Maternal-To-Embryonic Transition, Jocelyn Marie Cuthbert
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cloning animals using somatic cell nuclear transfer (scNT) was first successfully demonstrated with the birth of Dolly the sheep, but the process of cloning remains highly inefficient. By improving our understanding of the errors that may occur during cloned cattle embryo development, we could obtain a greater understanding of how specific molecular events contribute to successful development. The central dogma of biology refers to the process of DNA being transcribed into messenger RNA (mRNA) and the translation of mRNA into proteins, which ultimately carry out the functions encoded by genes. The epigenetic code is defined as the array of chemical …
Enhancing The Production And Sustainability Of Pasture-Fed Beef Using Non-Traditional Legume Forages, Andrea I. Bolletta
Enhancing The Production And Sustainability Of Pasture-Fed Beef Using Non-Traditional Legume Forages, Andrea I. Bolletta
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Despite the increasing worldwide demand for beef as a protein source, consumers are concerned about the sustainability of ruminant production systems. Their main concerns are animal welfare for feedlot-fed animals, greenhouse gas (GHG) emissions, global warming and worker safety. Traditional feedlot-based beef production systems have been associated with locally greater levels of soil, water and air contamination, as well as the overuse of antibiotics and growth hormones. The use of legume pastures such as cicer milkvetch (CMV) and birdsfoot trefoil (BFT), which fix their own nitrogen (N) and often contain beneficial secondary compounds such as tannins and provide for rapid …
Investigating Nest Box Utilization By Bumble Bees And Reproductive Development Of Male Bumble Bees, James Daniel Herndon
Investigating Nest Box Utilization By Bumble Bees And Reproductive Development Of Male Bumble Bees, James Daniel Herndon
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Bumble bees (Bombus Latrielle) are a wide-spread group of pollinating insects that are important species to conserve across many environments to ensure both ecological and economic resiliency because they pollinate important agricultural, horticultural, and wild flora. Surprisingly, fundamental questions still remain about this important charismatic group of pollinators. The investigations in this thesis are but two of many topics that require further research. The topics investigated are understanding bumble bee nest site preferences and reproductive development of both sexes of bumble bees. The first experiment (Chapter 2) investigates whether nest boxes elevated off of the ground and attached to …
Rumination And Quality Of Life Among Northern Plains Indians, Devon S. Isaacs
Rumination And Quality Of Life Among Northern Plains Indians, Devon S. Isaacs
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Native Americans (NAs) share unique risk factors for poor mental health. In response, mental health providers must address barriers to treatment while making the most of low resource situations. One way to increase usefulness of treatment is to address the mechanisms underlying multiple mental health disorders. Rumination is a style of thinking marked by repeated thoughts about distress and is well-recognized as a diagnostic factor for underlying disorders in the general population. Secondary data from the Mood Disorder Assessment Validation with Northern Plains Indians (NPI) pilot study was used to examine the relationship between rumination and anxiety, depression, and substance …
Interactions Between Water-Stress And Maize Resistance To Spider Mites With Varied Host Specialization, Gunbharpur S. Gill
Interactions Between Water-Stress And Maize Resistance To Spider Mites With Varied Host Specialization, Gunbharpur S. Gill
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Spider mites are well-documented pests of many agricultural crops including cereals such as maize. In hot and dry conditions, when crop plants are under water-stress, spider mite populations can rapidly increase within weeks and can cause severe yield losses. One approach to manage pests, such as spider mites, is through the development and selection of plants that can resist pests. Screening of maize lines has provided evidence of spider mite resistance; however, it is unclear how plant water-stress may affect the ability of maize to sustain spider mite resistance. In addition, it is important to understand how plants respond to …
A Data-Driven Regional Model Of Stomatal Conductance For Kruger National Park, Rebecca L. Tobin
A Data-Driven Regional Model Of Stomatal Conductance For Kruger National Park, Rebecca L. Tobin
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Stomata are the gateway between the lithosphere, the biosphere, and the atmosphere. Because of photosynthesis, plants inevitably lose water through their stomata. The rate at which water moves through stomata is stomatal conductance. As stomatal conductance increases, the rate of CO2 assimilation increases, therefore, plants must reach a balance between acquiring CO2 and losing H2O. Plants achieve this balance by adjusting stomatal aperture. Therefore, modeling stomatal conductance is important to global circulation models and land surface models, as well as for predicting how changing climate conditions affect water use efficiency and plant productivity, and has implications …
