An in situ nitric acid analyzer has been designed for sensing in the remote atmosphere. Its operation is based on measuring the concentration difference between the total odd nitrogen species (NO(y)) and HNO(3)-scrubbed NO(y). NO(y) was measured by an NO-ozone chemiluminescent detector equipped with a molybdenum converter. A temperature-controlled annular denuder coated with NaCl was used as a ...

The Southwestern region of the United States is extremely wealthy in low sulfur coal resources which must be eventually utilized in response to national energy balance priorities. Fly ash and scrubber sludge can be safely disposed of using properly managed techniques to ensure that any potential impact from elements such as boron, molybdenum, or selenium is rendered insignificant. Alternative m...

obstruction. Because ofthe irregular rhythm, the redundant (and unresected) anterior mitral valve leaflet may be in a more open position at the time of ventricular systole, predisposingto an enhanced Venturi effect and hence greater obstruction. Since drug therapy, heart rate, blood pressure, body position (at the time of echocardiogram), and volume status were similar at the time of both studi...

A three-terminal device based upon a two-dimensional electron system is investigated in the regime of nonequilibrium transport. Excited electrons scatter with the cold Fermi sea and transfer energy and momentum to other electrons. A geometry analogous to a water jet pump is used to create a jet pump for electrons. Because of its phenomenological similarity we name the observed behavior the “ele...

In Architecture, the modernists applied scientific principles to create stark designs that were functional but flouted convention. Robert Venturi, whose 1966 book “Complexity and Contradiction in Architecture” defined Post-modernism, criticized this minimalist approach. He celebrated instead the rich mix of historic styles found in great cities such as Rome, which many people find more comforta...

Jet mixing devices ("Venturi" devices) can be used in conjunction with domiciliary oxygen concentrators and provide delivered oxygen concentrations similar to those obtained with medical oxygen, though with the devices delivering higher concentrations (above 30% oxygen) the total flow is substantially reduced. A jet mixing device driven by a domiciliary concentrator would be valuable in various...

• Kelvin-Helmholtz Instability forms in cavitating microchannels. Governs Cavitation Cloud Shedding Microchannels. This is the third mechanism of cavitation cloud shedding. High Speed and X-ray visualization was performed. Simple model for flow developed. The paper shows inside a micro-Venturi channel. While initial aim study to establish supercavitating conditions micro-Venturi, yet we found t...
