Relative Effectiveness Of A Radionuclide (210pb), Surface Elevation Table (Set), And Lidar At Monitoring Mangrove Forest Surface Elevation Change, Richard Mackenzie, Ken Krauss, Nicole Cormier, Eugene Eperiam, Jan Van Aardt, Ali Rouzbeh-Kargar, Jessica Grow, Val Klump

Articles

Sea-level rise (SLR) is one of the greatest future threats to mangrove forests. Mangroves have kept up with or paced past SLR by maintaining their forest floor elevation relative to sea level through root growth, sedimentation, and peat development. Monitoring surface elevation change (SEC) or accretion rates allows us to understand mangrove response to SLR and prioritizes resilient ecosystems for conservation or vulnerable ecosystems for restoration. We compared three methods to measure SEC and accretion in mangrove forests: 210Pb, surface elevation tables (SETs), and a terrestrial light detection and ranging system (compact biomass LiDAR—CBL). Lead-210 accretion rates were not significantly …

Research outputs 2022 to 2026

Significant amounts of hydrocarbon resources are left behind after primary and secondary recovery processes, necessitating the application of enhanced oil recovery (EOR) techniques for improving the recovery of trapped oil from subsurface formations. In this respect, the wettability of the rock is crucial in assessing the recovery and sweep efficiency of trapped oil. The subsurface reservoirs are inherently contaminated with organic acids, which renders them hydrophobic. Recent research has revealed the significant impacts of nanofluids, surfactants, and methyl orange on altering the wettability of organic-acid-contaminated subsurface formations into the water-wet state. This suggests that the toxic dye methylene blue (MB), …

Quantifying Non-Muscle Myosin 2 Filament Dynamics, Melissa Ann Quintanilla

Dissertations

Non-muscle myosin 2 is a motor protein that, when assembled into filaments, works on the actin cytoskeleton to produce contractile forces within cells. This type of myosin dynamically assembles within cells to exert forces necessary for a wide variety of functions including cell division, migration, and multicellular movement. The ability to dynamically assemble contractile networks, and the ability to control the assembly and placement of these myosin filaments in both space and time, is therefore required throughout cell physiology. We used a suite of dynamic, quantitative imaging approaches to identify deterministic factors that drive myosin filament appearance and amplification as …

Evaluating The Efficacy Of A Thermoresponsive Hydrogel For Delivering Anti-Collagen Antibodies To Reduce Posttraumatic Scarring In Orthopedic Tissues., Andrzej Steplewski, Jolanta Fertala, Lan Cheng, Mark Wang, Michael Rivlin, Pedro K Beredjiklian, Andrzej Fertala
