Understanding Students’ Global Interdependence In Science Instruction, Walter S. Smith
Understanding Students’ Global Interdependence In Science Instruction, Walter S. Smith
Journal of Global Education and Research
Multiple American educational organizations such as the National Education Association, Association for Supervision and Curriculum Development, and the Council of Chief State School Officers have advocated for globalizing the K-12 curriculum. The National Science Teaching Association (NSTA) in a position statement on international education and the Next Generation Science Standards have produced goals and standards for internationalizing the science curriculum by addressing topics such as climate change, environment, and disease that cross borders. In contrast to those pronouncements on the curriculum, this article views global science education through an instructional lens that focuses on a students’ global interdependence in science …
Investigation Of Immobilized Enzymes In Confined Environment Of Mesoporous Host Matrices, Xiaoliang Wang
Investigation Of Immobilized Enzymes In Confined Environment Of Mesoporous Host Matrices, Xiaoliang Wang
USF Tampa Graduate Theses and Dissertations
Enzyme immobilization in metal-organic frameworks (MOFs) as a promising strategy, is attracting the interest of scientists from different disciplines with the expansion of MOF’s development. Different from other traditional host materials, their unique strengths of high surface areas, large yet adjustable pore sizes, functionalizable pore walls, and diverse architectures make MOFs an ideal platform to investigate hosted enzymes, which is critical to the industrial and commercial process. In addition to the protective function of MOFs, the extensive roles of MOFs in the enzyme immobilization are being well-explored by making full use of their remarkable properties like well-defined structure, high porosity, …
Flow Visualization And Aerosol Characterization Of Respiratory Jets Exhaled From A Mannequin Simulator, Sindhu Reddy Mutra
Flow Visualization And Aerosol Characterization Of Respiratory Jets Exhaled From A Mannequin Simulator, Sindhu Reddy Mutra
USF Tampa Graduate Theses and Dissertations
It is important to understand the airborne transmission of infectious diseases due to the COVID-19 pandemic. Physical experiments were conducted to understand the dispersion of aerosols emitted from a mannequin simulator replicating human tidal breathing through the nose and mouth with and without a protective face mask in an enclosed space. Flow patterns are observed via high-speed visualization, and the concentration and size distribution of the particles is measured as a function of distance from the mannequin using an optical particle sizer. Masks were shown to effectively reduce the horizontal dispersion of aerosol for both mouth and nose breathing. Further, …
An Automated Framework For Connected Speech Evaluation Of Neurodegenerative Disease: A Case Study In Parkinson's Disease, Sai Bharadwaj Appakaya
An Automated Framework For Connected Speech Evaluation Of Neurodegenerative Disease: A Case Study In Parkinson's Disease, Sai Bharadwaj Appakaya
USF Tampa Graduate Theses and Dissertations
Neurodegenerative diseases affect millions of people around the world. The progressive degeneration worsens the symptoms, heavily impacting the quality of life of the patients as well as the caregivers. Speech production is one of the physiological processes affected by neurodegenerative diseases like Alzheimer’s disease, amyotrophic lateral sclerosis (ALS) and Parkinson’s disease (PD). Speech is the most basic form of communication, and the effect of neurodegeneration degrades speech production, thereby reducing social interaction and mental well-being. PD is the second most common neurodegenerative disease affecting speech production in 90% of the diagnosed individuals. Speech analysis methods for PD in clinical methods …
Investigating The Novel Role Of Dextromethorphan In Mitigating Oxidative Stress Induced Changes In Retinal Pigment Epithelial Cells (Rpe), Zeinab A. Mohamed
Investigating The Novel Role Of Dextromethorphan In Mitigating Oxidative Stress Induced Changes In Retinal Pigment Epithelial Cells (Rpe), Zeinab A. Mohamed
USF Tampa Graduate Theses and Dissertations
Oxidative stress contributes to the degeneration of retinal pigment epithelial (RPE) cells and photoreceptors that lead to the dry form of age-related macular degeneration. Activation of N-Methyl-D-aspartate (NMDA) receptors contributes to the increase of free radicals that induce oxidative stress-induced changes. Our study investigates if Dextromethorphan, an NMDA receptor antagonist, reverses oxidative stress-induced changes in RPE. We used Paraquat and H2O2 as oxidative stress-inducing agents to induce oxidative damage in human ARPE-19 cells. To illustrate the change in cell viability and measure the apoptosis of ARPE-19 cells from oxidative damage, we performed MTT assay and Annexin V-DAPI flow cytometry analysis. …
