Development of a New Type Ultrasonic Gas Flowmeter

DEStech Transactions on Social Science, Education and Human Science, 2017
In this paper, a new method on how to design ultrasonic gas flow meter is presented. Ultrasonic sensor with large area and center frequency 120kHz is selected and ultrasonic sensor driving circuit based on IRF7389 is designed to drive the sensor, the received ultrasonic signal can reach 1000mv in the distance of 30cm, thus can make the amplifying ...

A Simple Regeneration Process Using a CO2‐Switchable‐Polarity Solvent for Cellulose Hydrogels

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The effect of transformation of the anion chemical structure on cellulose solubility by flowing CO2 gas into aqueous pyrrolidinium hydroxide solutions was investigated. The changes in anion structure allowed for the modulation of cellulose solubility in aqueous pyrrolidinium hydroxide solutions, thus establishing a simple and safe cellulose ...

No evidence of higher peak heat tolerance in the afternoon or with opportunity for thermal behaviour during low‐intensity work in uncompensable heat

Experimental Physiology, EarlyView.
Abstract Heat tolerance is known to be limited by high brain temperature, but most findings pertain to strenuous exercise following artificially altered baseline temperature or with limited opportunity for behaviour. Therefore, we investigated the hypotheses that thermal perceptions, hyperventilation and cerebrovascular responses would be exacerbated ...
