K D. Hyrenbach, Zora McGinnis, Kathleen Paige, Dan Rapp, F. D. Horgen, Jennifer Lynch
While the occurrence of plastic ingestion in the large-sized dolphinfish and tunas taken by the Hawaii longline fishery is very low ( 5 %), the ingestion rates for the smaller fish caught with pole-and-line have not been documented. This study examined

Domain Interactions Determine the Conformational Ensemble of the Periplasmic Chaperone SurA

Dagan C. Marx, Mathis J. Leblanc, Ashlee M. Plummer, Susan T. Krueger, Karen G. Fleming
SurA is thought to be the most important periplasmic chaperone for outer membrane protein biogenesis. Its structure is composed of a core region and two peptidylprolyl isomerase domains, termed P1 and P2, connected by flexible linkers. As such these three

SCALABLE THERMAL SIMULATION OF POWDER BED FUSION

October 1, 2020
Author(s)
Paul Witherell, Vadim Shapiro, Yaqi Zhang
Powder bed fusion (PBF) has become a widely used additive manufacturing (AM) technology to produce metallic parts. As the PBF process is driven by a moving heat source, consistency in part production, particularly when varying geometries, has proven

Simplified kilogram traceability for photon momentum radiometers

October 1, 2020
Author(s)
Kyle A. Rogers, Paul A. Williams, Gordon A. Shaw, John H. Lehman
High power laser applications in areas such as laser processing of materials can require an accurately measured laser power. Radiation pressure-based laser power measurement has been proven as a practical method for quantifying these high-power levels in
