... The oxygen increase also was monitored by measuring the activation of oxygen-16. This latter method employs fast neutron ...

It is suggested that a reduction in pressure vessel diameter could be achieved by substituting a thin layer of lithium hydroxide for the outer portion of the reflector. It is effective in reducing the fast flux through the high slowing-down power of the hydrogen and also of the lithium and oxygen. In order to determine the ...

The radial and axial transport of oxygen in the fuel pin of a fast breeder reactor has been described by a kinetic model. Oxygen is transported in fast reactor fuel pin among temperature gradients which changes the initially uniform distribution of oxygen...

The specific characteristics of a cw supersonic CO chemical laser utilizing a nonequilibrium chemical source of atomic oxygen were studied experimentally and theoretically. It was found that fairly high energy characteristics may be achieved by scaling the source. An observed reduction in the output energy was attributed to an anomalously ...

A novel concept of discharge oxygen-iodine laser (DOIL) is presented. The supersonic DOIL includes a discharge singlet oxygen generator (DSOG) and discharge atomic iodine generator (DAIG). The operation of DSOG is based on a fast mixing of hybrid argon plasma jet of DC electric arc and RF discharge with a neutral molecular ...

A new technique has been developed for nonintrusive in situ measurement of oxygen concentration, gas

High temperature oxygen sensors are widely used for exhaust gas monitoring in automobiles. This particular study explores the use of thin film single crystalline samaria doped ceria as the oxygen sensing material. Desired signal to noise ratio can be achieved in a material system with high conductivity. From previous studies it is ...

... was designed as a fast sensor for use as a propellant (hydrogen, helium, oxygen, ... This limit is imposed by the electrical properties of the electron ...

In order to properly characterize the rapidly fluctuating oxygen levels within the bed, a diagnostic oxygen instrument must have a wide measurement range, on the order of 0.2 to 10/sup -20/ atm, and a very fast response time, on the order of 30 ms. The Bosch automotive oxygen sensor was found to be the best ...

The use of oxygen-implanted silicon substrates for CMOS SOI device technology has great potential for use in VLSI and radiation-hardened circuits. The electrical characterization of such substrates is described by reference to CMOS devices fabricated directly into them; no epitaxial silicon was grown. Electrical parameters were related to the ...

The development of discharge singlet oxygen generators (DSOG's) that can operate at high pressures is required for the power scaling of the discharge oxygen iodine laser. In order to achieve efficient high-pressure DSOG operation it is important to understand the mechanisms by which singlet oxygen (O2(a1?)) is ...

Introduction Pressure-sensitive paint (PSP) is an optical pressure sensor that utilizes the oxygen quenching of luminescence. PSP measurements in unsteady aerodynamic flows require fast time response of the paint [1,2,3]. There are two characteristic time-scales that are related to the time response of PSP. One is the luminescent lifetime representing an ...

An interactive liquid oxygen (LOX) calculator for fasted channel catfish confined in grading nets or in live haul tanks has been developed, using Microsoft Visual Studio 2005©. The calculator is based on results of scientific experiments on channel catfish metabolism, and estimates oxygen consumptio...

Previous studies have shown that if European sea bass are exercised after feeding, they can achieve a significantly higher maximum metabolic rate (MMR) than when fasted. They can meet combined metabolic demands of digestion (specific dynamic action, SDA) and maximal aerobic exercise, with no decline in swimming performance. If, however, exposed to mild ...

In the present work, carried out in relation to the European and American Directives on the quality of petrol and diesel fuels, the simultaneous determination of the oxygenate compounds and BTEX in gasoline was achieved through the use of a multidimensional GC (MDGC)/MS system, employing a Deans switch-based transfer system, with an innovative ...
