Second language proficiency may be predicted with electrophysiological techniques. In a machine learning application, this electrophysiological data may be used for language instructors and language students to assess their language learning. This study identifies how electroencephalogram (EEG) power spectrum and cross spectrum data of the brain cortex relates to Spanish second language (L2) proficiency of 20 Spanish language students of varying proficiency levels at the University of New Hampshire. The two metrics for assessing cortical power and processing were event-related desynchronization (ERD)—a measure of relative change in power—of the alpha (8-12 Hz) brain frequency band, and alpha and beta (13-30Hz) …
Occurrence Of Per- And Polyfluoroalkyl Substances (Pfas) In New Hampshire Biosolids, Katherine A. Wieck
Occurrence Of Per- And Polyfluoroalkyl Substances (Pfas) In New Hampshire Biosolids, Katherine A. Wieck
Honors Theses and Capstones
Per- and polyfluoroalkyl substances (PFAS) are a group of over 4,000 compounds used in the manufacturing of products including aqueous film forming foams for firefighting, stain repellents, waterproofing agents, and nonstick cookware since their initial development in the 1940s. The long fluorinated carbon chain structure of PFAS causes chemical and thermal stability, and thus resistance to biodegradation. Biosolids produced at wastewater facilities for uses such as agricultural land-applied compost and fertilizer for lawns and athletic fields, as well as sludge disposed in landfills can cause contamination of groundwater and surface water. This poses a significant threat to human and environmental …
Investigation Of Mechanical Regulation On Stat3 Activity And Mmp Production, Jaxson R. Libby
Investigation Of Mechanical Regulation On Stat3 Activity And Mmp Production, Jaxson R. Libby
Honors Theses and Capstones
Transcription factor, STAT3, is inappropriately expressed in cancer cells, and has contrasting activation in 2D versus 3D microenvironments. 2D plates are often used for drug screening and do not always recapitulate in vivo responses. To combat inaccurate 2D drug studies, a 3D hydrogel was created to support the growth of cancer cells into a tumor-like environment. The hydrogel consists of a biocompatible dextran homopolysaccharide, cell adhesion RGD sequences, and crosslinker MMP labile peptides. A pH dependent reaction couples the RGD sequences to dextran then the polymers are crosslinked into a gel. Crosslinking is accomplished using terminal cysteine peptide sequences, allowing …
A Literature Analysis Of Microgrid Optimization Studies, Izzy Medeiros
A Literature Analysis Of Microgrid Optimization Studies, Izzy Medeiros
Honors Theses and Capstones
Senior civil engineering student, Izzy Medeiros, is presenting her honors thesis in the form of a literature analysis. Her research involved investigating existing microgrid studies and where there are current gaps in the knowledge. About 40 publications written within the last 20 years were analyzed for their research goals, optimization objectives, and microgrid design, pointing to where this research is currently lacking. Most real studies were conducted in Asia, as Southeast Asia has island communities that need the reliability of a renewable microgrid during extreme weather events. Photovoltaic panels in combination with wind turbines comprise the most common configuration of …
Reducing The Variability And Cost Of Determining The Coefficient Of Friction Of Various Lubricants, James M. Wirth
Reducing The Variability And Cost Of Determining The Coefficient Of Friction Of Various Lubricants, James M. Wirth
Honors Theses and Capstones
The Navy requires accurate fastener preloading for many of its fastened applications to protect the safety of the vessel and its personnel, and to ensure proper operation of various components. The preload is based on many properties including fastener materials, fastener geometries, and the coefficient of friction (COF) between mating surfaces. The COF is a critical value in determining the torque-load relationship of a fastener, and is dependent on the contact surface area and the materials in contact, the condition and finish of the contact surfaces, and any lubricant applied in these contact areas. Due to the large amount of …
