A mass flow meter includes an arcuate tube section that is semi-circular, an inner pressure sensor disposed on an inner curvature portion of the arcuate tube section and configured to capture an inner pressure measurement of the flowing fluid, an outer pressure sensor disposed on an outer curvature portion of the arcuate tube section and configured to capture an outer pressure measurement of the flowing fluid, and processing circuitry. The processing circuitry may be configured to receive the inner pressure measurement and the outer pressure measurement, determine a pressure difference between the inner pressure measurement and the outer pressure measurement, and determine a mass flow rate of the flowing fluid passing through the arcuate tube section based on the pressure difference and a fluid density of the flowing fluid.

A distillation column including a plurality of alternating plates and spacers stacked in a z-direction is provided. The plates include a respective liquid channeling network on a top surface thereof, a respective vapor opening, and a respective descending ramp. The respective descending ramps abut a respective liquid feed location of the plate immediately below to form a continuous liquid channeling network. The respective vapor openings of adjacent plates are located on opposite sides of the distillation column and form a continuous S-shaped vapor channel defined by the plurality of alternating plates and spacers, and the respective vapor openings. Systems including such distillation columns and processes of distilling a fluid mixture are also provided.

Stacked-plate distillation column

Described are systems for spatial cognitive ability assessment wherein a subject is able to manipulate one or more object(s) that is monitored by a device for recording motion attached to the object(s), the subject, or both that is able to generate motion electronic data. Also described are methods for assessing spatial cognitive ability.
