  • Chandler Loop Model for the Development of Dynamic Hemocompatibility Assays

    Creator:
    Hasbrook, AnneMarie V.
    Abstract:
    A common issue with extracorporeal medical devices is blood clotting due to bio-incompatibility. Systemic anticoagulants are often prescribed to mitigate the coagulation issues. However, such drugs can lead to further complications, for example hemorrhaging. One solution to improve the hemocompatibility of blood-contacting medical devices are biomaterials, such as slippery liquid...

  • Investigating the Potential for Cryopreservation of Human Granulocytes with Concentrated Glycerol

    Creator:
    Moss, Alden C.
    Abstract:
    Granulocytes are a class of white blood cells essential to immune function. Granulocyte transfusions hold promise to treat many conditions, but the short-shelf life of granulocytes makes transfusions infeasible without a cell preservation method. The purpose of this study was to investigate the potential for cryopreservation of granulocytes using 30%...

  • Beating Modes in Protostellar Disks

    Creator:
    Varga, Attila V.
    Abstract:
    Computational simulations of disks are becoming an important tool to predict the the evolution of protostars and disks to better understand the formation of planets. Past research has shown that the evolution of disks and their protostar can be altered through the interaction between gravity and hydrodynamic instabilities. We perform...

  • Novel Predictive Simulation of Organ Perfusion Kinetics for Design of Cryopreservation Procedures

    Creator:
    Johnson, Hill S.
    Abstract:
    Despite the many advances in biotechnology and biomedical engineering, the need for long term organ and tissue storage remains among the unsolved problems in the field. Researchers are investigating several possible solutions to the issue that aim to maintain the function and integrity of the biological tissues during storage and...

  • Detection and Segmentation of Bird Song in Noisy Environments

    Creator:
    Neal, Lawrence W.
    Abstract:
    Recent work in machine learning concerns the detection and identification of bird species from audio recordings of their vocalizations. Such analysis can yield valuable ecological information concerning the activity and distribution of species in the wild. Current species-identification methods require individual syllables of bird audio as input, but field-collected audio...

  • The Effects of Toxicity Inhibitors on the Cytotoxicity of Cryoprotective Agents using a High-Throughput Experimental Set-up

    Creator:
    Ampo, Emi
    Abstract:
    Even with advanced medical technology, there is still an unmet need for organs to reduce the transplant waiting list and to advance organ-related research. Cryopreservation through vitrification is one possible solution to increase organ availability. A major challenge with cryopreservation of organs is the toxicity of the cryoprotectants (CPAs) that...

  • The Effect of HSA and Hematocrit on the Cake Collapse Temperature of Lyophilized Red Blood Cells

    Creator:
    Runyon, Daniel E.
    Abstract:
    Freeze-drying, or lyophilization, has shown great promise in addressing many of the logistical challenges of storing and preserving red blood cells (RBCs). A crucial part of any future RBC lyophilization protocol is the primary drying temperature, which affects the sample drying rate and the dried cake’s ability to form a...

  • Comparing Metacarcinus magister settlement preferences among the seagrasses Z. marina and Z. japonica

    Creator:
    Jaco, Erin M. and Heidmann, Sarah
    Abstract:
    Metacarcinus magister, the Dungeness crab, is a commercially important species on the Pacific Northwest coast as the most profitable fishery in Oregon and an important ecological player as both predator and prey. Understanding the spatial distribution of Dungeness throughout different life history stages is beneficial both ecologically and economically. Zostera...

  • A Performance Evaluation of In-Stream Hatchboxes and Streamside Incubators for Chinook Salmon

    Creator:
    Howell, Meghan Z.
    Abstract:
    Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...
