Nano-Enhanced Composite Membranes For Water Desalination, Benjamin Fredrik Victor Sundling Von Fürstenrecht

Materials Engineering

In theory single walled carbon nanotubes (SWCNT) will aid in ion rejection due hydrophobicity and smoothness of the SWCNT. An efficient means of water desalination utilizing SWCNT in a membrane seems plausible. A lyotropic liquid crystal (LLC) solution was made with a synthesized polymerizable surfactant methacryloxy ethyl hexadecyl dimethyl ammonium bromide (C16MA) to help with vertical alignment of SWCNT. Due to SWCNT lack of solubility and tendency to agglomerate in water, a dispersion performed using an inert surfactant centrimonium bromide (CTAB) to make sure that the SWCNT were homogeneously dispersed in the solution without altering the hexagonal packing factor of …

At The Intersection Of Hope And Despair: Korea’S Uncertain Trajectory In The 1980s, Haley Noelle Cole

History

The 1980s in South Korea were defined by political factionalism and constant protest. The brief ecstasy afforded by the assassination of the dictatorial president Park Chung Hee in 1979 gave way to disillusionment with the policies of his successor, Chun Doo Hwan. Throughout Chun’s term, he sought to subvert popular perceptions of his authoritarian illegitimacy he earned through the bloody military coup with which he obtained power. Chun hoped to justify his presidency within the contexts of 1) the 1987 presidential election, wherein the country would witness its first peaceful transfer of power in the post-war era, and 2) the …

Rescue And Rehabilitation Of A Juvenile Red-Tailed Hawk: A Case Study, Maya Higa

Agricultural Education and Communication

Many raptor species are becoming threatened and, in some cases, endangered as a result of human activity including habitat destruction and pesticide use (Morishita, Fullerton, Lowenstine, Gardner & Brooks, 1998). Because of this, raptor rehabilitation has become increasingly popular in conservation efforts. In North America, the red-tailed hawk is one of the most widespread and commonly known birds of prey (Preston & Beane, 2009). According to the National Audubon Society, the conservation status of red-tailed hawks is currently of least concern and numbers may even be increasing in some areas since the 1960s. While this species is not threatened, the …

Consumer Choice Within Fresh Produce, Victoria C. Ross

Agricultural Education and Communication

This project set out to question whether fresh produce required more specific labeling of pesticides and fertilizer inputs on fresh produce.
