Abstract. Long et al. (2021) conducted a detailed study of possible interferences in measurements surface O3 by UV spectroscopy, which measures the transmission ambient and O3-scrubbed air. While we appreciate careful work done this analysis, there were several omissions, one case, type scrubber used was misidentified as manganese dioxide (MnO2) when fact it chloride (MnCl2). This misidentifica...

We created a Gold Standard corpus comprised over 20,000 records of annotated narrative clinical reports for use in the training and evaluation of NLM Scrubber, a de-identification software system for medical records. Our experience with designing the corpus demonstrated the conceptual complexity of the task.

long-throated flumes are measurement structures often used in water and wastewater systems to determine the flow discharge. the head-discharge relationship of long-throated flumes is traditionally determined following the critical flow theory and the boundary layer concept. after a review of the traditional approach and an analysis of the approximate assumptions of the boundary layer approach, ...

RESUMO O objetivo deste trabalho foi avaliar o potencial do Venturi para a síntese de biodiesel partir óleo comestível residual em rota metílica. Para tanto, construído escala laboratório um aparato experimental constituído tanque 5,2 L e dispositivo projetado produzir fenômeno cavitação. A produção avaliada três diferentes pressões entrada Venturi: 4,4; 2,9; 1,4 bar. Os teores ésteres metílico...

This paper reports a new microfluidic method for pumping fluid and the generation of droplets and bubbles using the Venturi principle, driving flow using pressure without numerous connections or extensive external control systems. The 2-layer devices in PDMS have no moving parts, and can pump fluid at flow rates >

background: in this study, an electroscrubber was designed and experimented for e valuation of integrating particle and droplet charging effects separately and jointly on collection efficiency of a spray tower and also to discover the optimal condition. methods: a homogenous concentration of relatively fine particles was introduced to influent air stream and electroscrubber efficiency in purify...

This paper evaluates the speciation and partitioning of mercury in two Spanish pulverised coal combustion power plants (PP1 and PP2), equipped with wet limestone-based flue gas desulphurisation facilities (FGD) operating with forced oxidation and re-circulation of FGD water streams. These plants are fed with coal (PP1) and coal/pet-coke blends (PP2) with different mercury contents. The behaviou...

A rheolytic thrombectomy catheter was used to remove thrombus without thrombolytics from the sigmoid and transverse sinuses of a 34-year-old woman. Using small, high-flow fluid jets and Venturi-effect suction, this catheter allowed mechanical removal of thrombus. This technique may obviate the need for thrombolytic agents and the risks associated with their use.
