Effect Of Plasma Treatment On Soil Degradation Of A Biodegradable Mulch Film, Swapnil Bhattacharya Dec 2022

Effect Of Plasma Treatment On Soil Degradation Of A Biodegradable Mulch Film, Swapnil Bhattacharya

Theses

Biodegradable Mulch Films (BMFs) offer a sustainable alternative to traditional non-degradable PE mulch films. However, their slow rate of biodegradation can lead to plastics accumulation in the soil. In this study, a commercially available BMF based on polybutylene adipate co-terephthalate (PBAT) and polylactic acid (PLA) is examined. Here the effects of gliding arc plasma treatment on the bulk and surface properties, as well as its soil degradation behavior, is studied. An increase in surface oxygen containing species and hydrophilicity was observed following plasma treatment. Only a small hydrophobic recovery was noted over 30 days. No changes in the bulk polymer …

Policy Recommendations For Concussion Recovery: Using Evidence Based Data For A Safe Return To Learn In Student-Athletes, Maya Vanderhorst

Theses

The return of concussed students and student-athletes to the classroom is commonly referred to as return-to-learn (RTL). RTL, however, is often overshadowed by returning a student-athlete back to athletic competition (return-to-play), with few recommendations and studies evaluating the effect of improper management of recovery from a concussion in an academic setting. Therefore, the research proposed here aims to track how symptom severity, student behaviors, and oculomotor performance formulate our ability to prognosticate how a student will respond to academic stimuli post-injury. This will be achieved by longitudinally tracking student-athletes as they recover from concussion, using a repeated measures design to …
