Summary Allelopathy is the inhibition of growth of one species of plants by chemicals produced by another, typically competing, species. The chemical compounds released in this phenomenon have the potential to be used as natural weed control agents. In this study, we tested kudzu (Pueraria montana) to determine its allelopathic potential for weed control and…

Characterization of a UPEC degS mutant in vitro and in vivo
Summary Escherichia coli DegS is an integral inner membrane protein that breaks down incorrectly assembled proteins and helps regulate the σ ᴱ stress response pathway. When degS is deleted, approximately 200-fold more outer membrane vesicles (OMVs) are produced. As OMVs contain sections of the outer membrane and proteins from the periplasm, they may play a…
On the Relationship Between Viscosity and Surface Tension
Summary Flow rates and pulling forces were measured in several solutions to determine the correlation between surface tension and viscosity. Because these fluid properties arise from intermolecular bonding, a positive correlation was expected. To study the relationship between viscosity and surface tension, solutions with different concentrations of agar and flour were used. Differences in viscosity…
Temperature and precipitation responses to a stratospheric aerosol geoengineering experiment using the Community Climate System Model 4
Summary As the global climate continues to change it may become critical to explore possibilities for climate intervention and remediation to counteract warming by greenhouse gases. One such ‘geoengineering solution’ proposes to inject reflective aerosol particles into the atmosphere to decrease insolation, the amount of radiation coming from the sun received by the Earth. Given…
The Analysis of the Effects of Smoke and Water Vapor on Insect Pheromone Communication and Physical Condition: An Investigation of the Causes of Colony Collapse Disorder
Summary Since the outbreak of honey bee (Apis mellifera L.) disappearance in the phenomenon known as colony collapse disorder (CCD) in 2006, investigations dedicated to finding the causes of CCD have suggested possible factors; however, a singular cause has not yet been identified. This project aims at identifying how external factors in the environment, such…
