When systems integrators and engineers require the measurement of gas flow rate in scientific research or in an industrial process, they have the choice of several types of technologies. The challenge ...

Precisely formulated gas mixtures with known concentrations of particular target gases are referred to as calibration gas standards. To guarantee the accuracy of gas concentration measurements, almost ...

As today's science and engineering focuses more and more on micro technology, the requirement to be able to measure and control extremely low gas mass flow rates has become very important. With ...

IN the 1908 Christian Herter Lectures at Bellevue Hospital, Starling 1 emphasized the important influence of changes in hepatic interstitial-fluid formation on flow and composition of thoracic-duct ...
