Extinction Treatment in Polarized Neutron Experiments

1980
I The purpose of this training is to show that polarized neutron experiments, which do not depend on any scale factor, are very dependent on extinction and provide us with original tests for extinction treatment. Neutrons are two-spin state particles and polarized neutron beam is composed of neutrons in only one spin state. Collecting the intensities P+

An Experiment on Spontaneous Flame Oscillation Prior to Extinction

Combustion Science and Technology, 1978
Abstract Experiments were conducted to study the spontaneous flame oscillation phenomena before the flames go to extinction. A number of liquid and solid fuels were tested in several different flame geometries using different extinction modes. In most cases, spontaneous flame oscillations were observed near the limit.

Experiments on Submillimeter Free Droplet Flame Extinction

Combustion Science and Technology, 2013
Flame extinction of n-heptane, n-decane, and n-hexadecane droplets freely falling through hot gases from a flat flame burner was investigated. Initial droplet diameters were in the range 270–285 µm. The hot gases from the flat flame burner were injected into straight and contoured flow tubes, providing flow environments that had various degrees of ...

A Theoretical Examination of an Experiment on Differential Resistance to Extinction

Transactions of the Kansas Academy of Science (1903-), 1955
McClelland (4) points out that a major paradox in learning theory is the fact that laboratory learning shows none of the persistance which we must assume characterizes human learning, especially learned motivation. McClelland refers to the fact that avoidance learning is more difficult to extinguish than other learning, and he assumes that the reason ...

Oscillation and extinction thresholds of the clarinet: Comparison of analytical results and experiments

The Journal of the Acoustical Society of America, 2007
In the context of a simplified model of the clarinet in which the losses are assumed to be frequency independent the analytic expressions of the various thresholds have been calculated in a previous paper [Dalmont et al., J. Acoust. Soc. Am. 118, 32–94 (2005)]. The present work is a quantitative comparison between “theoretical” values of the thresholds

A new radiometer for monitoring fire extinction experiments

Journal of Physics E: Scientific Instruments, 1974
A design is described for a new type of radiometer for monitoring flame radiation in fire extinction experiments. The radiometer uses a photocell and eliminates many of the practical difficulties encountered with the conventional thermocouple type of radiometer currently in use.

Sustainability ROX: Return on experience, return on extinction

Scene
In an age of extremes, hot and cold, war and peace, wealth and austerity, to have electricity and to not … what do we focus on? The innovations that have changed our perceptions are almost imperceptible to the naked eye. The arts are the last to be funded and the first to be cut, and yet, we can prove their value and worth very substantially through ...
