Involvement Of Poly(Adp-Ribose)Ylation (Parylation) In The Regulation Of Antioxidant Defense System In Arabidopsis Thaliana Under Salt Stress, Rengi̇n Özgür Uzi̇lday

Turkish Journal of Botany

Posttranslational modifications (PTM) are one of the first responses of plants to environmental stress and involve changing the location and activity of proteins in the cell. Addition of poly(ADP-ribose) (PAR) to proteins, poly(ADP-ribose)ylation (PARylation), is a posttranslational modification resulting from the binding of ADP-ribose from NAD+ to target proteins by PAR polymerases (PARP). PARylation is involved in many physiological events in plants including abiotic and biotic stress response. The aim of this work was to understand involvement of PARylation in inducing enzymatic antioxidant defence and alternative electron sinks in response to salinity. For this purpose A. thaliana plants were treated …

Entrepreneurial Ecosystems And Industry Knowledge: Does The Winning Region Take All?, Yating Li, Martin Kenney, Donald Patton, Abraham Song

All Faculty Open Access Publications

Entrepreneurial ecosystems (EE) are composed not only of startups but also the organizations that support them. Theory has been ambivalent about whether an EE is spatially bounded or includes distant organizations. This exploratory study uses a time series of all Internet industry initial public offerings (IPO) to explore the locational changes not only of startups but also four key EE service providers: lawyers, investment bankers, venture capitalists, and board directors. We find that while the startups became only slightly more concentrated, the EE service providers concentrated more rapidly, as an industry center in Silicon Valley emerged. Our results suggest that …

Strength In Numbers: A Field Experiment In Gender, Influence, And Group Dynamics, Olga B. Stoddard, Christopher F. Karpowitz, Jessica Preece

Faculty Publications

Policy interventions to increase women’s presence in the workforce and leadership positions vary in their intensity, with some including a lone or token woman and others setting higher quotas. However, little is known about how the resulting group gender compositions influence individuals’ experiences and broader workplace dynamics. In this paper, we investigate whether token women are disadvantaged compared to women on majority-women mixed-gender teams. We conducted a multi-year field experiment with a top-10 undergraduate accounting program that randomized the gender composition of semester-long teams. Using laboratory, survey, and administrative data, we find that even after accounting for their proportion of …

Incorporating High-Fidelity Aerostructural Analyses In Wind Turbine Rotor Optimization, Denis-Gabriel Caprace, Adam Cardoza, Andrew Ning, Marco Mangano, Sicheng He, Joaquim R. R. A. Martins

Faculty Publications

s demand grows for wind turbines with larger blades, the design of future wind turbines must account for multi-physical interactions and an ever-increasing number of design load conditions. One aspect, aerostructural coupling, calls for design tools that are both accurate and computationally efficient. In this paper, we present a combined-fidelity approach that couples high-fidelity computational fluid dynamics and computational solid mechanics simulations, with a conventional aeroelastic turbine modeling tool based on blade element momentum and beam theories. The approach is integrated into a multidisciplinary optimization framework. It takes advantage of the high-fidelity tightly-coupled aerostructural simulations to evaluate the rotor power …

Closed Loop Recycling Of Low Friction Polymers In Fused Granule Fabrication Additive Manufacturing Processes, Neil Thompson, Jason Weaver

Faculty Publications

Plastic waste is a critical worldwide problem that impacts additive manufacturing (AM). Extensive research has explored how plastic waste in AM can be reduced by recycling prints into new filament, with varying success. An alternative to filament-based extrusion is “fused granule fabrication” (FGF), which extrudes from pellets or granules. This method is often used for large area additive manufacturing (LAAM) of polymers. This paper expands upon the knowledge base from previous research on LAAM and examines the extent to which PETG can be recycled and reprinted through the same FGF tool without significant loss to its material properties. The metric …

Durability Of Vacuum Infusion Tooling Produced From Fused Granular Fabrication Additive Manufacturing, Nathan Northrup, Jason Weaver, Andy R. George

Faculty Publications

Large area additive manufacturing (LAAM) has the capability to create tooling that is lower cost than conventionally manufactured tooling and still has sufficient properties for many applications. A vacuum infusion mold was printed from fiberglass-ABS and evaluated for wear and suitability for small vacuum infusion runs. The mold was designed to accentuate high wear as a “worst case” scenario. The mold was able to produce 10 parts successfully before any noticeable change occurred to the surface finish. By 14 parts, the surface finish had roughened sufficiently that demolding was difficult and resulted in damage to the part. Profilometry measurements showed …

Reading Rate Gain In A Second Language: The Effect Of Unassisted Repeated Reading And Intensity On Word-Level Reading Measures, Grant Eckstein, Krista Rich, Ethan Lynn

Faculty Publications

Repeated reading is a popular intervention used to help struggling readers by exposing them to the same text multiple times. While the approach has been effective in L1 and some EFL settings, little research has explored its effectiveness compared against a control group or among ESL learners. Our study examined reading rate gains using words per minute and four eye-tracking measures with 46 mid-intermediate ESL learners grouped into three 14-week treatment groups: a control group that read 26 text passages (about two per week) just once through, another that read the same passages twice in each sitting, and a third …

Megaliths And Monumental Architecture At Coal Bed Village, An Ancestral Pueblo Site In Southeastern Utah, James R. Allison, Fumi Arakawa, Marion Forest, Katie K. Richards, David T. Yoder

Faculty Publications

Worldwide, megaliths are a common form of monumental architecture in Neolithic and later societies. Archaeologists in western Europe, and other parts of the world where megalithic monuments occur, have often discussed the meanings of megalithic features as well as their associations with ritual, territoriality, and social organization. In the Pueblo Southwest, most monumental architecture takes the form of large, unusually tall buildings (“great houses”), oversized ritual architecture (“great kivas”), or landscape features (roads and berms), all of which are most commonly associated with the Chaco system. Ancestral Pueblo people also occasionally built with ostentatiously large rocks, but megalithic features and …

Ability To Consent To A Sexual Assault Medical Forensic Examination In Adult Patients With Serious Mental Illness, Leslie W. Miles, Eleanore Knox, Nancy Downing, Julie L. Valentine

Faculty Publications

When a patient reporting a sexual assault (SA) presents with signs and symptoms of serious mental illness (MI), medical providers or forensic examiners may have concerns regarding the ability to legally consent to a sexual assault medical forensic examination (SAMFE). Numerous encounters have occurred where a SAMFE was not offered to a cooperative adult patient because the patient exhibited signs and symptoms of MI. Medical providers and examiners may be motivated by beneficence (believing that treating the patient's MI must take priority over the SAMFE) and/or non-maleficence (a concern that the in-depth SAMFE may worsen the patient's psychological state). Situations …
