Abrupt Climate Change in the Southern Great Plains during the Last Glacial Interval
(2017-04-27)
Understanding how the climate of the North American Great Plains may change in the future is of tremendous socioeconomic importance, yet the regional response to previous abrupt global climate events, such as the ...
PCL Shape Memory Scaffolds Prepared with Variable Cross-Link Density
(2017-04-28)
Poly(ε-caprolactone) (PCL) has been previously studied as a thermoresponsive shape memory polymer (SMP) for numerous biomedical applications due to its biocompatibility and biodegradability. We have previously investigated ...
Tunable Release of BMP-2 From Thiol-ene Click Hydrogels
(2017-05-01)
With over 6.3 million fractures that occur in the United States each year, autogenic and allogenic bone sources are becoming a dwindling resource. Bone Morphogenetic Protein-2 (BMP-2) has been shown to induce osteoblast ...
Synthesis and Characterization of Bioactive PANI-PAMPSA Nanoparticles Dispersed in Poly(HEMA)-based Hydrogels
(2017-05-03)
The distribution of water within and its relation to the electrical impedance of electroconductive hydrogels (ECH) is of interest in developing stimuli-responsive hydrogel membranes for in-dwelling biomedical sensors. ...
Prediction of Material Removal Rate in Die-Sinking Electrical Discharge Machining
(2017-05-02)
This project proposes a new model for material removal rate (MRR) of conductive materials using die-sinking electrical discharge machining (EDM). Five different engineering materials were used in this study. Small holes ...
Experimental Studies Towards Understanding the Aeromechanics of a Flexible Robotic Hummingbird Wing in Hover
(2017-04-25)
This study investigated the aeroelastic mechanics of a flexible flapping wing designed and implemented on a two-winged, flapping wing, robotic hummingbird capable of hovering. The investigation focused first on measuring ...
Mineralogy Associated With Acid Mine Seepage as Determined Using Fourier Transform Infrared Spectroscopy and Relations to Acid Base Accounting
(2017-04-27)
Over 7,000 km of streams in the eastern United States are negatively affected by acid drainage from coal mines (U.S. Environmental Protection Agency, 1994). Pyrite (FeS2) is known to be the primary cause of acid formation, ...
On Access and Excess: Birth Interventions for Latinas in the U.S.-Mexico Border Region
(2017-05-04)
The United States southern border is expanding rapidly. Already home to over 7.2 million people, this region also contains two of the nation's top ten fastest growing cities (McAllen, Texas and Laredo, Texas) (DHHS 2009; ...
Evaluating Potential Effects of Antarctic Ice-Shelf Retreat on Blue Whale (Balaenoptera musculus) Populations: A Simulation Model of Interactions Among Sea Ice, Antarctic Krill (Euphausia superba), and Blue Whales
(2017-04-24)
In the Antarctic, blue whales (Balaenoptera musculus) feed primarily on Antarctic krill (Euphausia superba), which feed primarily on under-ice algae. The retreat of the Antarctic ice shelf may pose potentially serious ...
Zen Routing
(2017-04-27)
Driving induced stress is a problem inherent to contemporary living in urban areas. Traffic congestion, route unpredictability, and other factors cause undue stress to commuters daily. This project’s purpose is to alleviate ...
