The Biowall Field Test Analysis and Optimization

Jacob J. Torres (5930906) 14 May 2019 (has links)
<div> <p>A residential botanical air filtration system (Biowall) to investigate the potential for using phytoremediation to remove contaminants from indoor air was developed. A full scale and functioning prototype was installed in a residence located in West Lafayette, Indiana. The prototype was integrated into the central Heating, Ventilating, and Air Conditioning (HVAC) system of the home. This research evaluated the Biowall operation to further its potential as an energy efficient and sustainable residential air filtration system.<br></p> <p> </p> <p>The main research effort began after the Biowall was installed in the residence. A field evaluation, which involved a series of measurements and data analysis, was conducted to identify treatments to improve Biowall performance. The study was conducted for approximately one year (Spring 2017-Spring 2018). Based on the initial data set, prioritization of systems in need of improvement was identified and changes were imposed. Following a post-treatment testing period, a comparison between the initial and final performances was completed with conclusions based on this comparison. </p> <p> </p> <p>The engineering and analysis reported in this document focus on the air flow path through the Biowall, plant growth, and the irrigation system. The conclusions provide an extensive evaluation of the design, operation, and function of the Biowall subsystems under review.</p> </div> <br>

TEACHER SUPPORTS USING THE FACILITATOR MODEL FOR DUAL CREDIT IN OPEN ENDED DESIGN THINKING COURSEWORK: UNIVERSITY COLLABORATION AND HIGH SCHOOL IMPLEMENTATION

Scott Tecumseh Thorne (10730865) 30 April 2021 (has links)
The facilitator model for dual credit offers a way for student to earn directly transcripted credit to colleges and universities, overcoming many barriers faced by other dual credit models. Successful implementation of this model requires high degree of involvement from the cooperating institution. This IRB approved qualitative case study explored the needs of five teacher facilitators in both summer professional development and on-going support throughout the school year when implementing a facilitator model for dual credit with open-ended design coursework. Code-recode and axial coding techniques were applied to over 90 hours of transcribed data, artifacts, and observations from a seven month period to find emerging themes and offer recommendations for implementation.<p></p>
