Evaluating The Efficacy Of A Hybrid Nutrition Course Offered To On-Campus And Distance Education Students, Mary Anne Dimmick
Evaluating The Efficacy Of A Hybrid Nutrition Course Offered To On-Campus And Distance Education Students, Mary Anne Dimmick
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A record high number of students enrolled in The Science and Application of Human Nutrition (NDFS 1020), during the Spring semester of 2010. With enrollment rates projected to continue to rise, NDFS 1020 faculty recognized that the existing traditional, lecture-based course structure did not allow for further growth of the program if academic integrity was to be upheld. NDFS 1020 was, consequently, transitioned to a hybrid format presenting 2/3 of the course experience online, and the remaining 1/3 in a face-to-face format. Hybrid NDFS 1020 was offered to distance education and on-campus students alike beginning in the Fall semester of …
Design And Testing Of Digitally Manufactured Paraffin Acrylonitrile-Butadiene-Styrene Hybrid Rocket Motors, Jonathan M. Mcculley
Design And Testing Of Digitally Manufactured Paraffin Acrylonitrile-Butadiene-Styrene Hybrid Rocket Motors, Jonathan M. Mcculley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Hybrid motors that employ non-toxic, non-explosive components with a liquid oxidizer and a solid hydrocarbon fuel grain have inherently safe operating characteristics. The oxidizer is blown though the solid fuel where it is combusted through a nozzle to produce thrust. This research investigated the combination of Acrylonitrile-butadiene-styrene impregnated with paraffin wax as the solid fuel component burned with nitrous oxide. The paraffin provides an enhanced regression rate over ABS; however, it lacks structural integrity and combustion efficiency. Multiple fuel grains with various ABS-to-Paraffin mass ratios were fabricated and burned with nitrous oxide. Analytical predictions for end-to-end motor performance and fuel …
Development Of The Multiple Use Plug Hybrid For Nanosats (Muphyn) Miniature Thruster, Shannon Dean Eilers
Development Of The Multiple Use Plug Hybrid For Nanosats (Muphyn) Miniature Thruster, Shannon Dean Eilers
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Multiple Use Plug Hybrid for Nanosats (MUPHyN) prototype thruster incorporates solutions to several major challenges that have traditionally limited the deployment of chemical propulsion systems on small spacecraft. The MUPHyN thruster offers several features that are uniquely suited for small satellite applications. These features include 1) a non-explosive ignition system, 2) non-mechanical thrust vectoring using secondary fluid injection on an aerospike nozzle cooled with the oxidizer flow, 3) a non-toxic, chemically-stable combination of liquid and inert solid propellants, 4) a compact form factor enabled by the direct digital manufacture of the inert solid fuel grain. Hybrid rocket motors provide …
