The purpose of this study is to investigate the relative performance of compact ionization chambers as it changes based on the speed of detector motion and collection volume. To quantify changes, multiple scans were made with each of a selection of compact chambers and repeated varying detector speed. Each scan...
The buildup of reactive oxygen species (ROS) and reactive nitrogen and oxygen species (RNS) is known as oxidative stress. Oxidative stress results in a wide variety of modification to biological macromolecules including nucleic acids, lipids, and proteins. For at least 30 years it has been known that high levels of...
Sites in need of restoration typically have one or more environmental factors that limit seedling establishment; identifying ecophysiological responses to environmental stressors can be advantageous in growing seedlings able to overcome such constraints on survival. To maximize survival after outplanting, seedlings should be grown in a manner that considers both...
Intertidal herbivores, such as isopods, help regulate and contribute to nutrient cycling and organic carbon flow through the trophic levels in estuaries and coastal ecosystems. Though much is known about the microbiomes of macrophyte leaves that serve as the primary food source for isopods, and (to a lesser extent) the...
Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...
The inverse electron demand Diels Alder reaction between tetrazines and strained alkenes is an exceptionally useful tool in functionalizing to biomolecules since it is orthogonal to the chemistry of most living systems and have exceptionally high rate constants. In particular reactions between strained trans-cyclooctenes (sTCO) and tetrazines can achieve second...
The combined activities of diverse heterotrophic marine microorganisms significantly shape global biogeochemical cycles, but models of these activities are currently limited to aggregate microbial community processes, and it remains unclear how community structure and the functional roles of specific microbial taxa should be integrated into these models. Therefore, understanding the...
Studying human’s ability to estimate temporal durations could lead to a greater
understanding of our cognitive abilities as well as the processes that underlie temporal
estimation. It has been shown through previous research that time and number may be
interconnected cognitively and that the magnitude of one may alter the...
An ideal labeling reaction between protein and surface should generate a protein-patterned surface with control over the orientation of the desired protein. Controlling orientation would generate a homogeneous, un-fouled protein surface and allow for maximum efficiency in regards to the activity, reactivity, and stability of the protein. In this research...
A specific tyrosine post-translational modification, called 3-nitro-tyrosine (nitroTyr), has been known to be present on an essential calcium signaling protein called calmodulin (CaM) during oxidative stress. While protein-bound 3-nitro-tyrosine has long been considered a biomarker of OS, it is also hypothesized to be a mechanism for protein signaling. However, purification...
