Snow Evolution In A Changing Climate, Abigail Brazil Jun 2021

Snow Evolution In A Changing Climate, Abigail Brazil

ENGS 88 Honors Thesis (AB Students)

Climate change is rapidly melting ice and snow worldwide, increasing the production of meltwater on ice sheets and glaciers. Depending on temperature, porosity, and saturation conditions, meltwater may move horizontally as runoff, refreeze into ice, or be stored as a liquid within the snow. When water is stored in the snow for multiple years, it is considered a perennial firn aquifer. These aquifers have received recent attention due to their potential to act as a buffer against sea level rise. Though it is still unclear if this connection truly exists, these features remain of interest to scientists trying to understand …

ENGS 88 Honors Thesis (AB Students)

Infections are responsible for over half a million neonatal deaths every year (Lawn et al., 2014). Thus, there is huge interest in leveraging maternal immunization against infectious diseases to grant fetal protection during its development through the vertical transferring of IgG antibodies, the only Ig subclass that can significantly cross the placental barrier. Studies about vertical immunization rely on in-vitro models to extrapolate physiological conditions of the human placenta. The BeWo Transwell model (Bode et al., 2006) presents itself as a reliable model to mimic the transplacental transport mechanism of antibodies (Ellinger et al., 1999; Poulsen et al., 2009) …
