Well-Scale Multiphase Flow Characterization And Validation Using Distributed Fiber-Optic Sensors For Gas Kick Monitoring, Jyotsna Sharma, Otto L.A. Santos, Giuseppe Feo, Oloruntoba Ogunsanwo, Wesley Williams

Faculty Publications

Early detection of a gas kick is crucial for preventing uncontrolled blowout that could cause loss of life, loss of assets, and environmental damage. Multiphase flow experiments conducted in this research demonstrate the capability of downhole fiber optic sensors to detect a potential gas influx in real-time in a 5000 ft deep wellbore. Gas rise velocities estimated independently using fiber optic distributed acoustic sensor (DAS), distributed temperature sensor (DTS), downhole gauges, surface measurements, and multiphase flow correlations show good agreement in each case, demonstrating reliability in the assessment. Real-time data visualization was implemented on a secure cloud-based platform to improve …

A Molecular Toolset For The In Vivo Detection Of A Sulfolobus Islandicus Leucyl Trna Synthetase Paralog, Nicholas Michael Bretz

Theses and Dissertations

An ancient and ubiquitous set of enzymes known as the aminoacyl-tRNA synthetases are required for the viability of all organisms. The aminoacyl-tRNA synthetases catalyze the attachment of amino acids onto tRNA molecules. The aminoacylated, or charged, tRNA is then transported and utilized at the ribosome for the synthesis of proteins. The genome of the hyperthermophilic microorganism Sulfolobus islandicus (S. islandicus) harbors a unique leucyl-tRNA synthetase paralog, LeuRS-I, of unknown function. While its duplicate, LeuRS-F, carries out all the classical functions of LeuRS-family enzymes, LeuRS-I fails to charge leucine onto tRNALeu, despite its ability to activate this amino acid and bind …

Spectral Absorption Coefficient Of Additive Manufacturing Materials, Nicholas J. Wallace, Matthew R. Jones, Nathan B. Crane

Faculty Publications

Active thermography techniques are of interest for quality assurance of additive manufacturing processes. However, accurate measurements of thermophysical properties of materials are required to successfully implement active thermography. In particular, the spectral absorption coefficient of materials commonly used in additive manufacturing must be known to accurately predict the spatial distribution of thermal energy generated from absorption of power emitted by a laser or pulsed flash lamp. Accurate measurements of these optical properties are also needed to develop greater understanding of additive manufacturing processes that rely on radiative heat transfer to fuse powders. This paper presents spectral absorption coefficient measurements and …

Biology Faculty Articles

Homotherium was a genus of large-bodied scimitar-toothed cats, morphologically distinct from any extant felid species, that went extinct at the end of the Pleistocene [1–4]. They possessed large, saber-form serrated canine teeth, powerful forelimbs, a sloping back, and an enlarged optic bulb, all of which were key characteristics for predation on Pleistocene megafauna [5]. Previous mitochondrial DNA phylogenies suggested that it was a highly divergent sister lineage to all extant cat species [6–8]. However, mitochondrial phylogenies can be misled by hybridization [9], incomplete lineage sorting (ILS), or sex-biased dispersal patterns [10], which might be especially relevant for Homotherium since widespread …

One Step Closer To A Better Starling Trap, James R. Thiele

Human–Wildlife Interactions

European starlings (Sturnus vulgaris) are an invasive species in the United States that damage agriculture, personal property, and threaten human health and safety. The U.S. Department of Agriculture Wildlife Services provides technical support to mitigate damage by controlling starling populations at concentrated animal feeding operations, landfills, utilities, and urban areas. Wildlife Services uses DRC-1339, a registered toxicant, to reduce starling populations. Trapping can also be an effective tool but requires more time at a higher cost than DRC-1339. Trapping starlings, however, may be needed to provide a viable alternative to mitigate damage in areas where toxicant use may …

Modeling Migratory Nongame Birds: A Plea For Data, George M. Linz

Human–Wildlife Interactions

The Bird Damage Management Conference held February 10–13, 2020 in Salt Lake City, Utah, USA provided a forum for professionals from across the United States to discuss and share management approaches, research strategies, policy, and messaging regarding the management of blackbirds (Icteridae), starlings (Sturnus vulgaris), corvids (Corvidae), and vultures (Cathartidae). Mathematical models were presented at the conference and subsequently discussed in a special issue of Human–Wildlife Interactions. Rapidly changing landscape variables point to the need for detailed systematic population monitoring programs with specific objectives. Nationwide periodic monitoring would provide data about changes not only in bird populations …

Tolerance Of Bearded Vultures To Human Activities: Response To Comor Et Al. (2019), Olivier Duriez, Antoni Margalida, Luc Albert, Beatriz Arroyo, Virginie Couanon, Hélène Loustau, Martine Razin, Jean-Baptiste Mihoub

Human–Wildlife Interactions

The bearded vulture (Gypaetus barbatus) is listed as vulnerable in Europe on the International Union for Conservation of Nature Red List because of population declines over multiple generations. Vulture population declines have been attributed to shooting, use of toxicants, and changes in land use, which have resulted in habitat degradation and increased anthropogenic disturbances. Concomitantly, conservation authorities have restricted practices deemed harmful to the species and have established protection buffers around occupied vulture breeding sites to mitigate the impacts of anthropogenic disturbances on breeding success. Comor et al. (2019) compared bearded vulture breeding success over 6 years within …

Black Vulture Conflict And Management In The United States: Damage Trends, Management Overview, And Research Needs, Bryan M. Kluever, Morgan B. Pfeiffer, Scott C. Barras, Brett G. Dunlap, Lee A. Humberg

Human–Wildlife Interactions

Contrary to rapid declines of many vulture (Accipitridae, Cathartidea) species worldwide, black vulture (Coragyps atratus) populations are increasing and expanding their range in North America. Vultures exhibit complex behaviors and can adapt to any human-dominated landscape or land use. These traits, combined with population growth and range expansion, have contributed to increased human–vulture conflicts. Our goal was to summarize the current status and trends in human–black vulture conflicts (hereafter human–vulture conflicts), review available management strategies, identify knowledge gaps, and provide recommendations to enhance management and understanding of this species and the associated conflicts. We found human–vulture conflicts are …

The Emerging Conflict Of Common Ravens Roosting On Electric Power Transmission Line Towers In Montana, Usa, Marco Restani, James S. Lueck

Human–Wildlife Interactions

Bird interactions with electric power lines can cause faults (e.g., disruption of electrical service). Faults on 500kV transmission lines in Montana, USA, which are integral to the Northwest USA power grid, became concerning during winter 2016–2017. In 2017 we found insulators contaminated with bird droppings and discovered a large nocturnal roost of common ravens (Corvus corax). To assess the potential magnitude of the impact of raven roosts on electric power transmission, we summarized fault data obtained from the Energy Management System and raven abundance data obtained from the Christmas Bird Count in central Montana from 2005 to 2020. …

Salinomycin Inhibits Proliferative Vitreoretinopathy Formation In A Mouse Model., Alison M. Heffer, Victor Wang, Richard T. Libby, Steven E. Feldon, Collynn F. Woeller, Ajay E. Kuriyan

Wills Eye Hospital Papers

Proliferative vitreoretinopathy (PVR) is a progressive disease that develops in a subset of patients who undergo surgery for retinal detachment repair, and results in significant vision loss. PVR is characterized by the migration of retinal pigment epithelial (RPE) cells into the vitreous cavity, where they undergo epithelial-to-mesenchymal transition and form contractile membranes within the vitreous and along the retina, resulting in recurrent retinal detachments. Currently, surgical intervention is the only treatment for PVR and there are no pharmacological agents that effectively inhibit or prevent PVR formation. Here, we show that a single intravitreal injection of the polyether ionophore salinomycin (SNC) …

Movement Behavior Of Radio-Tagged European Starlings In Urban, Rural, And Exurban Landscapes, Page E. Klug, H. Jeffrey Homan

Human–Wildlife Interactions

Since their intentional introduction into the United States in the 1800s, European starlings (Sturnus vulgaris) have become the fourth most common bird species and a nuisance bird pest in both urban and rural areas. Managers require better information about starling movement and habit-use patterns to effectively manage starling populations and the damage they cause. Thus, we revisited 6 radio-telemetry studies conducted during fall or winter between 2005 and 2010 to compare starling movements (n = 63 birds) and habitat use in 3 landscapes. Switching of roosting and foraging sites in habitat-sparse rural landscapes caused daytime (0900–1500 hours) …

Nd2 As An Additional Genetic Marker To Improve Identification Of Diving Ducks Involved In Bird Strikes, Sarah A. M. Luttrell, Sergei Drovetski, Nor Faridah Dahlan, Damani Eubanks, Carla J. Dove

Human–Wildlife Interactions

Knowing the exact species of birds involved in damaging collisions with aircraft (bird strikes) is paramount to managing and preventing these types of human–wildlife conflicts. While a standard genetic marker, or DNA barcode (mitochondrial DNA gene cytochrome-c oxidase 1, or CO1), can reliably identify most avian species, this marker cannot distinguish among some closely related species. Diving ducks within the genus Aythya are an example of congeneric waterfowl involved in bird strikes where several species pairs cannot be reliably identified with the standard DNA barcode. Here, we describe methods for using an additional genetic marker (mitochondrial DNA gene NADH …

Social Media And Electronics’ Impacts On Psychological Well-Being, Meaghan Gleason

D.U.Quark

The use of electronics, specifically social media, has grown immensely in recent years along with the increase of mental illness, thus implying a possible correlation between the two. The use of digital media may have serious impacts on the psychological well-being of adolescents, teenagers, and adults. This review will focus on the specific psychological impacts that electronics and social media have on adolescents, along with the contributions social media has to the development of depression in all ages, and how language use can be accurate predictors of common mental conditions. It is unclear why depression, anxiety, bipolar disorder, sleep disorders …

Democratization As A Protective Layering For Crimes Against Humanity: The Case Of Myanmar, Anna B. Plunkett

Genocide Studies and Prevention: An International Journal

Myanmar has a history of state sanctioned violence against its own people. However, as the regime transition occurs the methods of conducting such violence have also changed. This has not led to an end to violence but an alteration in the methods used by the state. What can be identified is the use of democratic regime transition to legitimise the state’s actions whilst delegitimising the plight of communities that have historically resisted the state. By engaging in the minimal standards of democratic practice whilst developing relations with the international community on the basis of trade, Myanmar has been able to …
