Development Of A Coupled Fluid And Colloidall Particle Transport Model, Scott Ripplinger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A colloidal system usually refers to when very small particles are suspended within a solution. The study of these systems encompasses a variety of cases including bacteria in ground water, blood cells and platelets in blood plasma, and river silt transport. Taking a look at these kinds of systems using computer simulation can provide a great deal of insight into how they work. Most approaches to date do not look at the details of the system, however, and are specific to given system. In this study a program called OpenFOAM is used as a basis to build a computer simulation …

Development Of Standards, Objectives, And Curriculum Guide To Teach Basic Electronics For Utah Science Credit In Secondary School Education, Rick Pierce

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Recently, the Utah State Office of Education (USOE) has accepted Basic Electronics, Classification of Instructional Programs (CIP) code 47.0105, as an elective to fill the required third science credit for secondary education (grades 10-12) students. The current Utah state core standards and objectives used for curriculum development in the Basic Electronics classes are now inadequate, as they are more than 15 years old, and designed specifically for students pursuing a technical career path. A formatting change to the document was implemented in 2008, but the standards and objectives were not changed.
Students are subsequently being taught the fundamentals of technology …

Cationic Starch Synthesis, Development, And Evaluation For Harvesting Microalgae For Wastewater Treatment, Renil John Anthony

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Microalgae are the preferred crop for the production of biodiesel. Microalgae are microplants that have the ability to harness sunlight more efficiently than other plants and store 20-80% lipids per g of dry algae in their cells. Microalgae have the extraordinary ability to grow in brackish water or wastewater. Microalgae can be grown in municipal wastewater to uptake phosphorus and nitrogen and remediate the wastewater of these nutrients. Microalgae thus cultivated accomplishes a dual role of wastewater treatment and provides a sustainable feedstock for biofuels and other bioproducts.

This study focused on efficiently harvesting microalgae from water using modified starch. …
