Cathodoluminescence, the emission of light when atoms excited by high-energy electrons return to their ground state, is analogous to UV-induced fluorescence, and some materials such as zinc sulfide and some fluorescent dyes, exhibit both phenomena.

Cathodoluminescence and EBIC are referred to as " beam-injection " techniques, and are very powerful probes of the optoelectronic behavior of semiconductors, in particular for studying nanoscale features and defects.

Cathodoluminescence is most commonly experienced in everyday life as the light emission from the inner surface of the cathode ray tube in television sets and computer CRT monitors.

Cathodoluminescence is an optical and electrical phenomenon whereby a beam of electrons is generated by an electron gun and then impacts on a luminescent material such as a phosphor, causing the material to emit visible light.

Cathodoluminescence occurs because the impingement of a high energy electron beam onto a semiconductor will result in the promotion of electrons from the valence band into the conduction band, leaving behind a hole.

Cathodoluminescence is used in cathode ray tubes, photoluminescence in fluorescent lighting and plasma display panels, phosphorescence in safety signs and low energy lighting, fluorescence in pigments, inks, optical brighteners, safety clothing, and biological and medicinal analysis and diagnostics, chemoluminescence and bioluminescence in analysis, diagnostics and sensors, and electroluminescence in the burgeoning areas of light-emitting diodes ( LEDs / OLEDs ), displays and panel lighting.

Besides I heard her old uncle that stays there has been doin' it ''.

Southern resentment has been over the method of its ending, the invasion, and Reconstruction ; ;

The situation of the South since 1865 has been unique in the western world.

The North should thank its stars that such has been the case ; ;

As it is, they consider that the North is now reaping the fruits of excess egalitarianism, that in spite of its high standard of living the `` American way '' has been proved inferior to the English and Scandinavian ways, although they disapprove of the socialistic features of the latter.

In what has aptly been called a `` constitutional revolution '', the basic nature of government was transformed from one essentially negative in nature ( the `` night-watchman state '' ) to one with affirmative duties to perform.

For lawyers, reflecting perhaps their parochial preferences, there has been a special fascination since then in the role played by the Supreme Court in that transformation -- the manner in which its decisions altered in `` the switch in time that saved nine '', President Roosevelt's ill-starred but in effect victorious `` Court-packing plan '', the imprimatur of judicial approval that was finally placed upon social legislation.

Labor relations have been transformed, income security has become a standardized feature of political platforms, and all the many facets of the American version of the welfare state have become part of the conventional wisdom.

Historically, however, the concept is one that has been of marked benefit to the people of the Western civilizational group.

In recent weeks, as a result of a sweeping defense policy reappraisal by the Kennedy Administration, basic United States strategy has been modified -- and large new sums allocated -- to meet the accidental-war danger and to reduce it as quickly as possible.

The malignancy of such a landscape has been beautifully described by the Australian Charles Bean.

There has probably always been a bridge of some sort at the southeastern corner of the city.

Even though in most cases the completion of the definitive editions of their writings is still years off, enough documentation has already been assembled to warrant drawing a new composite profile of the leadership which performed the heroic dual feats of winning American independence and founding a new nation.

Madison once remarked: `` My life has been so much a public one '', a comment which fits the careers of the other six.

Thus we are compelled to face the urbanization of the South -- an urbanization which, despite its dramatic and overwhelming effects upon the Southern culture, has been utterly ignored by the bulk of Southern writers.

But the South is, and has been for the past century, engaged in a wide-sweeping urbanization which, oddly enough, is not reflected in its literature.

An example of the changes which have crept over the Southern region may be seen in the Southern Negro's quest for a position in the white-dominated society, a problem that has been reflected in regional fiction especially since 1865.

In the meantime, while the South has been undergoing this phenomenal modernization that is so disappointing to the curious Yankee, Southern writers have certainly done little to reflect and promote their region's progress.

Faulkner culminates the Southern legend perhaps more masterfully than it has ever been, or could ever be, done.

The `` approximate '' is important, because even after the order of the work has been established by the chance method, the result is not inviolable.

But it has been during the last two centuries, during the scientific revolution, that our independence from the physical environment has made the most rapid strides.

In the life sciences, there has been an enormous increase in our understanding of disease, in the mechanisms of heredity, and in bio- and physiological chemistry.

Even in domains where detailed and predictive understanding is still lacking, but where some explanations are possible, as with lightning and weather and earthquakes, the appropriate kind of human action has been more adequately indicated.

The persistent horror of having a malformed child has, I believe, been reduced, not because we have gained any control over this misfortune, but precisely because we have learned that we have so little control over it.

To achieve this goal, he has used the scattered terrorist attacks to create fear of terrorism, which he then exploited in order to get a security contract for his own private security firm at the Olympic games.

This can be exploited in order to detect any eavesdropping on communication ( which necessarily involves measurement ) and, more importantly, to calculate the amount of information that has been intercepted.
