Controlling the power output of a boiling water reactor (BWR)—such as Exelon Nuclear’s Quad Cities Unit 1 or 2 (Figure 1)—requires changing the reactivity of the core by repositioning the control rods ...

These all-in-one pump protection valves are designed to keep pumping systems in process, firefighting, refinery, power and chemical applications modulating and running smoothly, without cavitation or ...

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 ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Cardiovascular disease is the leading cause of death around the world, including the stiffening of artery walls known as atherosclerosis. Atherosclerosis develops at arterial sites where endothelial ...

SAVING MONEY AND conserving energy aren't always the first things on our customers' minds when asking about retrofitting or adding hot water recirculation systems — it's a desire for convenience and ...

The glucose infusion test (GIT) has been proposed as a simple and cheap alternative to the saline dilution technique for the detection of vascular access recirculation in patients on hemodialysis. The ...
