Bioprinting of Pancreatic Cancer Cells for Improved Drug Testing
(North Dakota State University, 2019)Currently, many drugs are preclinically tested on two-dimensional cell cultures. However, this method does not adequately replicate the cellular interactions or diffusion gradient that occur in three-dimensional tissues, ... -
Brain Tissue Mechanical Characterization and Determination of Brain Response under Confined Blasts Explosions
(North Dakota State University, 2015)Mechanical experimental tests including stress relaxation, simple monotonic ramps, and impact loads were performed on porcine brain tissues to investigate the response of the brain under different loading scenarios. Linear ... -
Breast Cancer Screening in Native American Women at an Urban Minnesota Community Clinic
(North Dakota State University, 2015)The Native American Community Clinic (NACC) in Minneapolis, MN, expressed a need for a breast cancer screening patient education brochure and a policy regarding breast cancer screening, due to the absence of these in their ... -
Cavitation Inception and Contaminant Effects
(North Dakota State University, 2014)Within a liquid, it is possible to lower the pressure to a point in which the nuclei gas bubbles will cause cavitation inception. During this drop in pressure, at constant temperature, the bubble tension will increase to ... -
