Abstract: Currently used flow equation of rotameter was obtained by analogy of orifice meter, which is not rigorous in theoretic. In this paper, according to the fluid motion characteristics in ...

Aeration in deep-flow liquid hydroponics provides oxygen for respiration, but even gentle movement from solution agitation can alter the beneficial rhizosphere. Here we report the detrimental effects ...

Abstract: A rotameter is a variable area type flow sensor. It is generally used as a local indicator and display unit. Hence, a special technique is needed to transmit and to display the reading of a ...

Flow cytometry is a technology for assaying labelled cells suspended in fluid and passed through a detector. The labels are usually fluorescent and used for counting and sorting the cells in a signal ...
