Novel Approach To Junctional Bleeding: Tourniquet Device Proposal For Battlefield Hemorrhage Control, Kyle W. Cabaniss

Master's Theses

This study investigated possible solutions to the current wartime problem of junctional hemorrhaging, or massive traumatic hemorrhaging in non-tourinquetable areas such as the neck, groin, or armpit. Junctional hemorrhaging has been identified as a major contributor to potentially survivable deaths seen on the battlefield today and therefore is a priority for the U.S. armed and coalition forces (Kragh et al., 2011a; Bozeman, 2011). Common tourniquets today are standard issue and carried by soldiers in the military, but are limited to distal extremity trauma. As the battlefield has changes however, trauma has transformed from commonly seen gunshot wounds to more extreme …

An Examination Of Summer Bridge Programs For First-Generation College Students, Emily Christine Otewalt

Psychology and Child Development

During the last fifty years, nearly half of all students who entered a two- or four-year university withdrew without obtaining a degree. Students from low socioeconomic backgrounds, ethnic minority students, and students who were the first in their family to attend college were particularly vulnerable to this attrition. The following senior project examines current research on the backgrounds and attrition rates of first-generation college students, how "Summer Bridge Programs" aim to assist these students, and where shortcoming exist in current "Summer Bridge Program" assessments.

Consumer Evaluation Of Low Sodium Mozzarella Cheese And Development Of A Novel Method For Evaluating Emotions, Lauren Alyse Collinsworth

Master's Theses

Mozzarella cheese is currently the highest consumed cheese in the United States. The popularity of mozzarella cheese is typically attributed to the high consumption rates of pizza cheese and string cheese; both of which are low moisture part skim (LMPS) mozzarella cheese. A single serving of LMPS mozzarella cheese contains approximately 8% of the daily value (DV) for sodium, a mineral which is currently consumed in excess among most Americans. On average, one in three Americans has hypertension. This condition is strongly associated with excessive sodium intake, and it is a leading risk factor for cardiovascular disease and stroke in …
