Significant hemodynamic changes occur immediately after birth in preterm infants. Amplitude-integrated electroencephalography (aEEG) provides a method of assessing brain activity in sick neonates; ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found -- in animal studies -- a close relationship between ...

An alternate method of measuring fractional flow reserve (FFR) may be more sensitive than the conventional approach in identifying ischemia-causing lesions, according to a small animal study published ...

Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through the orifice; bypassing involves routing part of the flow ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...
