Application of a Small Unmanned Aerial System to Measure Ammonia Emissions from a Pilot Amine-CO Capture System.

The quantification of atmospheric gases with small unmanned aerial systems (sUAS) is expanding the ability to safely perform environmental monitoring tasks and quickly evaluate the impact of technologies. In this work, a calibrated sUAS is used to quantify the emissions of ammonia (NH) gas from the exit stack a 0.1 MWth pilot-scale carbon capture system (CCS) employing a 5 M monoethanolamine (MEA) solvent to scrub CO from coal combustion flue gas.

Optometric Applications for Three-dimensional Printing: A Technical Report from Low Vision Rehabilitation Practice.

Significance: Delivering personalized three-dimensional (3D)-printed solutions for our patients is easier now than it has ever been. This technological revolution makes things possible that it would be extremely challenging to achieve using traditional approaches.

Purpose: The purpose of this study was to increase awareness among the optometric and vision science community of opportunities to apply 3D printing to enhance clinical practice and research.

Accuracy and clinical utility of a point-of-care HbA1c testing device.

Background: Point-of-care testing (POCT) is widely used to measure blood glucose levels in people with diabetes, although its use in measuring glycated hemoglobin (HbA1c) levels is less common, perhaps due to perceived performance issues and access to the technology.

Methods: Forty blood samples were analyzed in duplicate using Bayer's A1CNow + ® Multi-Test A1C system (A1CNow + ) with 3 different reagent lots; HbA1c levels of the samples spanned the clinically relevant range of 4% to 10%. Corresponding samples were sent to a National Glycohemoglobin Standardization Program (NGSP) secondary reference laboratory (University of Missouri Secondary Reference Laboratory #9), which analyzed the samples with a Tosoh Automated Glycohemoglobin Analyzer HLC-723G8 (Tosoh G8; Tosoh Bioscience, Inc).

Mass spectral analyses of corn stover prehydrolysates to assess conditioning processes.

Flow injection electrospray (FIE) and LC-tandem mass spectrometry techniques were used to characterize corn stover acid hydrolysates before and after overliming and ammonia conditioning steps. Analyses were performed on samples without fractionation (dilution only) in an effort provide an inventory of ionizable substances. Statistical evaluation of the results indicates that the ammonia-treated and crude hydrolysates were more similar to one another than any other pairing, with conditioning leading to a decrease in malate levels.
