The formation of white etching bands (WEBs), including both low- (LAB) and high- (HAB) angle bands, in the subsurface steel bearings due to rolling contact fatigue (RCF) has been investigated over decades understand their characteristics predict during operation. A few studies recently have modelled development LABs theoretically based on thickening lenticular carbides adjacent band controlled ...

In this study, we develop a framework for measuring the value of harmful algal bloom (HAB) predictions. The framework captures the effects of both private and public responses to HABs. Using data from the New England nearshore commercial shellfish fishery and impact estimates for a large-scale HAB event in 2005, we illustrate how the potential value of HAB forecasts may be estimated. The result...

Since 1990, coral reefs off southeast Florida have experienced an unprecedented succession of macroalgal blooms and invasions. To determine if anthropogenic land-based nitrogen (N) sources support these HABs, we collected macroalgal tissue for stable nitrogen isotope (dN) analysis at three spatially distinct depths ranging from the shallow subtidal to the shelf break ( 43 m) along seven transec...

Abstract. The Four Corners region, where Colorado, Utah, New Mexico, and Arizona meet, is the location of one most significant archaeological sites in United States, Lowry Pueblo Canyon Ancients National Monument. This case study examines two aspects documentation process for Pueblo. First, a collaborative model multiple stakeholders dedicated to an integrated digital analog approach. Second, m...

Marine heat waves (MHWs) have been associated with extensive harmful algal blooms (HABs) in the northeast Pacific Ocean, but degree to which these large-scale oceanographic events are mirrored nearshore environments has not well established. We compared phytoplankton assemblages Lower Columbia River Estuary (LCRE) during two MHWs that took place 2015 and 2019, observations from 2017, a year no ...

The occurrence of harmful algal blooms (HABs) is increasing in frequency and intensity South African estuaries because eutrophication. This study used DNA metabarcoding to identify the benthic diatom community structure eutrophic Sundays Estuary. recurrent HAB phytoplankton species Heterosigma akashiwo was recorded at bloom concentrations (?100 µg Chl a l?1) brackish, vertically stratified midd...

Rocky Mountains CESU announces 2013 Student and Project Team Award winners: The RM-CESU announced that the recipient of the 2013 Student Award is Julia Ausloos, University of Colorado Denver. Julia received a Masters in Historic Preservation from the School of Architecture and Planning. She worked on a National Park Service project, on BLM land, titled: NPS Historic American Building Survey (HA...

Cylindrospermopsin (CYN) is a freshwater algal toxin produced during the proliferation of harmful cyanobacteria, known as cyanobacterial blooms (cyano-HABs). Recently, effects global warming have facilitated growth cyano-HABs, leading to their worldwide occurrence and an increase in toxin-related damage aquatic ecosystems. CYN exhibit strong cell toxicity upon ingestion, inhibiting protein synt...
