Greenhouse Gas Emissions From Milk Production In The Us, Cailey Cooper
Greenhouse Gas Emissions From Milk Production In The Us, Cailey Cooper
Chemical Engineering Undergraduate Honors Theses
Life cycle assessment is performed to determine the environmental impacts of the life cycle of a product. In this study, the greenhouse gas emissions from milk production in the United States were calculated using a cradle-to-gate analysis. The dairy industry has a noticeable impact on the total greenhouse gas emissions in the US. Performing life cycle assessment provides information about the main emission sources in the life cycle which can spark innovative changes to reduce these emissions. The life cycle assessment was performed using the openLCA software and ReCiPe impact assessment methodology. The results indicated that 1.28 kg of carbon …
Comparing Firocoxib And Meloxicam In The Application Of Microneedle Patch For Transdermal Drug Delivery, Ruohan Li
Chemical Engineering Undergraduate Honors Theses
This thesis compares the performance of meloxicam and firocoxib in the aspects of its physical characteristic, chemical compositions, and in-vitro performances for transdermal pain management microneedle patches on farm animals. The microneedle patches are composed of polyvinyl alcohol (PVA), type I collagen (COL), and chitosan (CHI) as base material that carries NSAIDs to achieve therapeutic purposes. Scanning electron microscopy (SEM) was utilized to observe the morphological and physical characteristics of the microneedle patches. Both meloxicam and firocoxib microneedle patches were successfully prepared using the methodology, with organized microneedle distribution and sizing. And Fourier transform infrared spectroscopy (FTIR) confirmed the chemical …
