Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson, Fiona Goggin
Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson, Fiona Goggin
Inquiry: The University of Arkansas Undergraduate Research Journal
Plant elicitor peptides (Peps) – endogenous chains of amino acids involved in natural plant defense – have been shown to decrease damage from herbivores and pathogens by inducing an immune response, increasing the emission of volatile organic compounds (VOCS), transcripts, and metabolites. Exogenous treatment of soybean seeds with plant elicitor peptide GmPep3 has been shown to induce these broad-spectrum defenses and offers a new method for increasing crop yield. However, the effects of GmPep3 on indicators of soybean health – root characteristics, growth stages, etc. – have not been fully realized. Using the root-phenotyping platform RhizoVision Explorer, several root traits …
A New Design Method For Vanadium Redox Batteries In Renewable Energy Systems, Casey Gibson, Karla G. Morrissey Unversity Of Arkansas, Fayetteville
A New Design Method For Vanadium Redox Batteries In Renewable Energy Systems, Casey Gibson, Karla G. Morrissey Unversity Of Arkansas, Fayetteville
Inquiry: The University of Arkansas Undergraduate Research Journal
This study investigated the behavior of vanadium redox flow batteries (VRFBs), which are batteries capable of easily switching between charging and discharging modes, making them a suitable option for storing intermittent sources of alternative energies (solar, wind, etc). Since different sizes of the battery provide varying voltages, optimal parameters for a particular home are key for implementation. These parameters, specifically the cell and tank volumes of the battery that are capable of providing consistent on-load voltage, were determined using data from a 13 kW solar array and a medium-sized house. Charge/discharge current values were used to run a mathematical model …
Implementing A Food Waste To Compost Program At The University Of Arkansas: An Economic Feasibility Analysis, Zoe Teague
Implementing A Food Waste To Compost Program At The University Of Arkansas: An Economic Feasibility Analysis, Zoe Teague
Inquiry: The University of Arkansas Undergraduate Research Journal
The University of Arkansas Fayetteville (UAF) is actively pursuing ways to increase sustainability on campus. Through the establishment of the Sustainability Council and campus centers, multiple projects are attempting to reduce the carbon footprint at UAF. One particular study is designed to eliminate food waste on campus through composting. The purpose of this study was to evaluate and project the economic savings of implementing a food waste composting system using Earth Tubs. Earth Tubs are an in-vessel electrical composting system capable of diverting up to 150 pounds of organic material daily with minimal odor. Results suggest that composting food waste …
