Royal D. Alworth, Jr. Institute for International StudiesDr. Tobin Stanley, UMD Department of World Languages and Cultures, explores three documentaries based on Ángel Fernández’s testimonial narratives. Resistant fighter, sixteen-year political prisoner in Franco’s jails and current expatriate, Ángel Fernández has penned several written testimonies, participated in the documentary films Te doy mi palabra (I Give You My Word, 2012, dir. Quino González) and Au temps des roses rouges (Time of the Red Roses, 2013, dir. Francis Lapeyre), and protagonizes the biopic Ángel (2016, dir. Stéphane Fernandez). These works are a testament to his commitment to justice through memory. As a survivor of the cumulative traumas of war, exile and political imprisonment, his journey to make his story known through memory activism reach the apex of communication in the documentary Ángel.Item Anji'bide: Research as a transformative tool to improve community well-being (2022-11-16)(2022) University of Minnesota Duluth.

Department of Art and DesignThe Department of Art & Design at the University of Minnesota Duluth invites the public to our “virtual” Annual Student Exhibition (ASE). This Annual Student Exhibition is a juried show of work executed by students who took classes in the Department of Art & Design. This year’s jurors are graphic designer, Abby Haddican, and ceramist, Kimberlee Joy Roth. The virtual website was designed and created by students currently enrolled in Professor Jennifer Gordon's Graphic Design classes. The Annual Student Exhibition "Look Both Ways," features over 80 works of art from a range of media including: animation, ceramics, digital art, drawing, graphic design, motion graphics, painting, photography, printmaking, sculpture, and video. This year's exhibition looks back at the history of ASE, giving viewers a look at what's been done in the past, and what's currently happening. Join us in celebrating the work of our students by visiting the virtual exhibition!Item Annual Student Exhibition: Our Stories (2021)(2021) University of Minnesota Duluth.

Department of Chemistry and BiochemistryPlastics are a ubiquitous part of everyday life and a central challenge in the environment. Environmental stresses such as sunlight, temperature fluctuations, wet/dry cycling or microbial forces affect the longevity or degradation of plastics. Assessing the fate of plastics under these stresses allows us to accurately predict the service lifetime of plastics used in infrastructure (e.g., power cabling/solar panels) or evaluate the extent of the plastic pollution problem. This talk details the work of quantifying photochemical and thermal degradation mechanisms of plastics commonly found in aquatic plastic debris: polyethylene, polypropylene and polyethylene terephthalate. In this talk, I will focus on the development of a methodological framework for characterization of the rates and yields of the chemical transformations within polymers, moving beyond traditional materials characterization techniques. Additionally, we quantified the formation of microplastics upon photochemical weathering, applying our understanding of the chemical photo-transformations. Beyond the transformations of the plastics, we also began to unravel the role plastics and plastic weathering play on the ecosystem health by monitoring the sorption of model micropollutants to weathered plastics and the toxicity of nanoplastics to a model bacterium. Ultimately, this work strives to quantify the transformations and fate of plastics so as to design a predictive model of plastic behavior in the environment, which has implications for accurately assessing the burden of plastics on the environment but also allows for new polymer design.Item Bringing Pharmacogenomics to the Frontline of Care (2023-05-03)(2023) University of Minnesota Duluth.

Department of Chemistry and BiochemistryThe Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasiveprocedure that has grown in popularity in recent years. However, there has beendocumentation of many complications after this procedure, such as a mortality rate of8.4% for TAVR procedures compared to 4.8% for tissue surgery procedures after 90days for Medicare beneficiaries. The underlying mechanisms of the TAVR procedureand how the replacement valve changes the biomechanical and flow environmentafter implantation has not been well studied. Therefore, it is necessary to design amodel heart and create sensors to understand the underlying mechanisms of theTAVR procedure. The goal of this project is to design a sensor that can detectchanges in blood pressure and blood flow rates in a silicon model heart. Onepromising type of material is piezoelectric sensors. Piezoelectric materials takemechanical stress and create detectable changes in voltage that can be calibrated todetermine changes in pressure. One material that has been used for other sensors isPolyvinylidene fluoride (PVDF). This study will investigate how porosity of PVDFchanges the structural and mechanical properties of the polymer. Pores will beintroduced into the PVDF membrane by adding Zinc Oxide (ZnO) nanoparticlesduring the synthesis process and removing the ZnO particles once the membranehas dried. To study the changes in the structure of the membrane, Scanning ElectronMicroscopy is used to confirm a porous structure. To study how the chainconformation of the polymer changes with porosity, Fourier Infrared Spectroscopy isutilized. A Tensile Tester is used to apply compressive stress onto the PVDFmembranes to study the piezoelectric output. To allow for comparison betweenvarious porous membranes, the d33 coefficient is calculated. This will help determinewhich porosity is optimal for the creation of the biosensor with desired sensitivity.Item Characterizing the Changes to Protein Sorption to Photodegraded Polyethylene (2021-04-09)(2021) Fawcett, Liam; University of Minnesota Duluth. Department of Chemistry and BiochemistryAft er their entry into the environment, plastics are exposed to a multitude ofabiotic environmental factors that change both their physical and chemicalcharacteristics. While the initiation of biotic degradation on pristine polymershas been reviewed, it is generally accepted that biotic degradation is enhancedon polymers that initially have undergone some sort of abiotic degradation,particularly photodegradation. This work seeks to understand the intricacies ofbacterial interactions with plastics by investigating the interaction of proteins topolymers with increasing extents of photodegradation, which should giveinsight into the potential attachment and biofilm formation on plastic debrismaterials. Using bovine serum albumin (BSA) as a model protein, we haveinitially investigated the changes in structural characteristics and fluorescenceof the model protein as it adsorbs onto the surface of irradiated polyethylene.Changes to the secondary structure characteristics of BSA were monitoredthrough circular dichroism and preliminary data has shown that with anincrease in irradiation time, there is a characteristic shift of the 3.6 ?-helices tomore tightly wound 3.10 ?-helices. This is likely due to the increasedhydrophilicity of photodegraded polymers causing the hydrophobic residues towind more tightly. Fluorescence of the tryptophan’s in BSA shows a decreasewith exposure to the polymers regardless of irradiation time, indicating potentialfluorescence quenching from the surface of the polymer. Overall, these resultsindicate that an increase polyethylene irradiation time causes an increase ininteraction strength between the polymer and protein, which may explain howbiotic degradation is increased with abiotically degraded polymers. Ultimatelythis work will contribute to our understanding of the fate of plastics in theenvironment.Item China's Global Ambitions (2021-10-21)(2021) Freeman, Carla P; University of Minnesota Duluth. Royal D. Alworth, Jr. Institute for International StudiesItem The Chippewa National Forest Isn't Just Another Forest, It is a Homeland (2021-02-04)(2021) Thompson, Douglas P; University of Minnesota Duluth. Department of American Indian StudiesThe Chippewa National Forest is the first national forest in the National Forest System created by statute and the only National Forest created with explicit provisions for the benefit of a Tribal Nation. Over time, this history has faded from the corporate and collective memory of the United States Forest Service. The understand [sic] of this singularly unique relationship has been reconstructed over recent years, requiring a recalibration of natural resource management activities and planning on one of the most intensively managed Forests in the National Forest system.Item Chocolate in Trinidad (2021-10-05)(2021) Sternberg, Steven; University of Minnesota Duluth.
