A continuous flow process for the preparation of betahistine with a 90% isolated yield has been reported. 2-Vinylpyridine and saturated methylamine hydrochloride aqueous solution were used as starting ...

Oil-gas-water three-phase flow has multiple flow states that exhibits dynamic, nonlinearity and instantaneity. Real-time monitoring and analysis of flow state are crucial for ensuring safe operation ...

This paper presents a systematic development of optimal no flow process underfill parameters compatible with four commercially available fluxing underfills. A novel hybrid process was developed that ...
