Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Low-Cost Prosthetic Feet For Underserved Populations: A Comparison Of Gait Analysis And Mechanical Stiffness, Kaleigh Renninger, Brevin Banks, Dustin A. Bruening

Library/Life Sciences Undergraduate Poster Competition 2022

• Lower limb loss is an ongoing cause of disability throughout the world.
• Despite advancements in prosthetic technologies, there are numerous underserved populations in need of effective low-cost prosthetic foot options.

Improving And Modeling Bacteria Recovery In Hollow Disk System, Clifton Anderson

Theses and Dissertations

Identifying antibiotic resistance in blood infections requires separating bacteria from whole blood. A hollow spinning disk rapidly removes suspended red blood cells by leveraging hydrodynamic differences between bacteria and whole blood components in a centrifugal field. Once the red cells are removed, the supernatant plasma which contains bacteria is collected for downstream antibiotic testing. This work improves upon previous work by modifying the disk design to maximize fractional plasma recovery and minimize fractional red cell recovery. V-shaped channels induce plasma flow and increase fractional plasma recovery. Additionally, diluting a blood sample spiked with bacteria prior to spinning it increased the …

Beating Clusters Created With Cardiac Extracellular Matrix From Decellularized Pig Hearts And Repopulated With Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes, Isaac Myres, Bryce Allen, Silvia Moncada, Sebastian Valencia, Beverly L. Roeder, Alonzo D. Cook

Library/Life Sciences Undergraduate Poster Competition 2019

Due to the high prevalence of heart disease, scarcity of donors, and high risk of transplant rejection, we aim to engineer patient specific beating cardiac patches and whole hearts for transplant.

Soft-Tissue Artifact Compensation For Electromagnetic Motion Capture, George T. Dickinson, Steven K. Charles

Biomedical Engineering Western Regional Conference

This purpose of this study is to develop a soft-tissue artifact compensation algorithm for the upper arm using electromagnetic motion capture systems that can be implemented in a wide range of applications. This study focuses on compensation of humeral axial rotation and forearm axial rotation.

Biomedical Engineering Western Regional Conference

The purpose of this study was to determine how accurately serum COMP represents inflammatory cytokine levels, within the knee, before and after exercise.

Cytokines included: GM-CSF, IFNa2, IL-10, IL-12p40, IL-13, IL-15, IL-1ra, IL1b, IL1a, IL-4, IL-6, IL-8, IP-10, MCP-1, MIP-1a, MIP-1b and IL-17.

Differentiation And Containment Of Derived Pancreatic Beta Cells, Caden Duffy, Alonzo Cook Ph.D.

Biomedical Engineering Western Regional Conference

Currently, the only permanent cure for Type 1 Diabetes is a pancreatic or islet transplant. With the shortage of donors, we are progressing research towards alternative therapies by differentiating induced pluripotent stem cells into derived pancreatic β-cells that can be transplanted and used as treatment for Type 1 Diabetes. We are investigating methods to increase the yield of fully derived, insulin producing pancreatic β-cells and are additionally researching the use of hydrophilized expanded polytetrafluoroethylene for use in cell containment devices. These devices could offer a future alternative for islet transplantation in human patients.

Study Of The Time Efficiency And Volume Of Wood Used For Three Types Of Stove In The Salitrón Community Of San Juan Ermita, Department Of Chiquimula, Fredy Samuel Coronado López

Theses and Dissertations

In developing countries such as Guatemala, firewood is increasingly being used for cooking in most rural areas. Consequently, there is a shortage of firewood in these areas beca use trees do not grow at the same rate as they are consumed. Some authors report that 90% of the heat from firewood is lost during combustion. Several alternatives to open pit fires exist to reduce the amount of firewood used. However, these alternatives need to be evaluated to determine their efficiency. This project compared the time efficiency and volume of firewood used in the Finlandia style improved stoves, Josefina stoves, and …
