Methods Of Harvest And Compositional Characterization Of Hemp Fibers From Medical Cannabis Biomass Using Detergent Fiber Analysis, Abigail Lazier, Srishti Banerji, Jennifer Macadam, Bruce Bugbee

Publications

Medical cannabis production generates large quantities of stem biomass that is typically discarded despite its potential as a source of natural hemp fibers. This study developed and evaluated two methods for recovering fibers from greenhouse-grown medical cannabis using water retting and compared their composition with commercially produced industrial hemp fibers. Fiber quality was assessed using detergent fiber analyses to quantify cellulose, hemicellulose, and lignin fractions. Both harvest methods produced usable fibers, although one approach (method A) yielded cleaner fibers after shorter retting durations, while the second approach (method B) offered greater potential for large-scale processing. Increasing retting duration improved fiber …

Community Science For Enigmatic Ecosystems: Using Ebird To Assess Avian Biodiversity On Glaciers And Snowfields, William E. Brooks, Jordan Boersma, Neil Paprocki, Peter Wimberger, Scott Hotaling

Watershed Sciences Faculty Publications

Mountain glaciers and snowfields are rapidly receding because of climate warming. Species living in these habitats remain poorly studied, likely because of the remoteness and ruggedness of their terrain. We leveraged community science data from eBird—an online database of bird observations from around the world—to characterize bird use of mountain glaciers and snowfields. We estimated total bird biodiversity and preference for glaciers and snowfields over nearby, ice-adjacent habitats. We used field notes from eBird users and breeding codes to extend our data set to include insight into habitat usage and behavior. Finally, we compared our community-science approach to previous studies …

Development Of A High-Doppler Shift Optical Simulator To Test Femtosecond-Level Optical Time-Frequency Transfer, Matthew S. Bigelow, Kyle W. Martin, Nolan Matthews, Benjamin K. Stuhl, Richard Gonzales, Alexandre De Pinho E Braga, John Elgin, Kimberly A. Frey

Space Dynamics Laboratory Publications

We have developed an optical simulator to test real-time optical two-way time–frequency transfer at the femtosecond level capable of simulating relative motion between two linked optical clock nodes up to Mach 1.8 with no moving parts. The technique is enabled by artificially Doppler shifting femtosecond pulses from auxiliary stabilized optical frequency combs. These pulses are exchanged between the nodes to simulate the Doppler shifts observed from a changing optical path length. We can continuously scan the simulated velocity from 14 to 620 m s⁻¹ while simultaneously measuring velocity-dependent clock shifts at much higher velocities than previously recorded. This system …

Despite well-intentioned early hearing detection and intervention (EHDI) programs, parents receiving a newborn hearing loss diagnosis often experience distress, uncertainty, and fear, which can impact their readiness to engage in early intervention. The communication and support provided by clinicians in early hearing detection and intervention play a critical role in helping families navigate emotions, overcome barriers, and actively participate in EHDI programs. The purpose of this scoping review is to advance our knowledge of the following: For parents who have a newborn newly diagnosed with hearing loss, how do the actions/behaviors and communication (or lack thereof) of EHDI providers influence …

Geographic And Sociodemographic Disparities In Early Hearing Detection And Intervention Adherence, Amanda Pavan, Anton Kvit, Michael Van Skiba, Analise Ristic, Kirsten R. Coverstone

Journal of Early Hearing Detection and Intervention

Early identification and intervention are crucial to minimizing impacts of congenital hearing loss. Early Hearing Detection and Intervention (EHDI) programs recommend newborn hearing screening before one month of age and a diagnostic audiologic evaluation before three months for infants who do not pass the screening. However, not all infants meet these benchmarks, as geographic and sociodemographic factors may influence adherence.

Addresses of primary contacts and audiology clinics were geocoded to calculate drive times to the nearest clinic in 10-minute intervals for infants born in Minnesota between 2019 and 2021. Birth location, NICU admittance, and sociodemographic characteristics were also analyzed. Random …
