Helium-3, however, is a fermion particle, which can form bosons only by pairing with itself at much lower temperatures, in a process similar to the electron pairing in superconductivity.

Helium-3 is also produced via beta decay of tritium, which in turn can be produced from deuterium, lithium, or boron.

Helium-3 was hypothesized to be a radioactive isotope until helions were also found in samples of natural helium, which is mostly helium-4, taken both from the terrestrial atmosphere and from natural gas wells.

Helium-3 is also thought to be a natural nucleogenic and cosmogenic nuclide, one produced when lithium is bombarded by natural neutrons.

Helium-3 has a negative enthalpy of fusion at temperatures below 0. 3 K. Helium-4 also has a very slightly negative enthalpy of fusion below 0. 8 K. This means that, at appropriate constant pressures, heat must be removed from these substances in order to melt them.

Helium-3, an isotope of helium with two protons and one neutron, could be fused with deuterium in a reactor.

Helium-3 has a negative enthalpy of fusion at temperatures below 0. 3 K. Helium-4 also has a very slightly negative enthalpy of fusion below 0. 8 K. This means that, at appropriate constant pressures, heat must be added to these substances in order to freeze them.

Helium-3 is proposed as a second-generation fuel for nuclear fusion in hypothetical fusion power plants, but such plants are still very early in their development -- especially since the first generation has not entered service anywhere, yet.

Such colonies could export Helium-3 for use in fusion reactors if they ever become practical.

Helium-3 is proposed as a power source for spacecraft mainly because of its abundance on the moon.

In the late 21st century even some of Saturn's moons have been settled as a base for that planet's Helium-3 scooping operations.

Helium-3 is necessary in the fusion reactors that provide energy for virtually all electric systems, including the energy patterning nodes essential to the interstellar ZTT ( zero-temporal transit ) drive.

Bitek habitats usually orbit gas giants ( for the Helium-3 they contain ) and some, e. g. Tranquillity, have the ability to " jump " away from a battle.

Helium-3 occurs as a primordial nuclide, escaping from the Earth's crust into the atmosphere and into outer space over millions of years.

Teams earn money in Allegiance through the use of miners, drone craft which harvest Helium-3 from special asteroids.

Examples include Helium-3 extraction from the Moon, and solar power satellite systems.

One suggested trade commodity, Helium-3 ( He-3 ) from the solar wind, is thought to have accumulated on the Moon's surface over billions of years, but occurs only rarely on Earth.

Edenism wealth comes primarily from mining Helium-3 (< sup > 3 </ sup > He ) from gas giants.

Helium-3 ( He-3, sometimes called tralphium ) is a light, non-radioactive isotope of helium with two protons and one neutron.

Helium-3 boils at 3. 19 kelvin compared with helium-4 at 4. 23 kelvin, and its critical point is also lower at 3. 35 kelvin, compared with helium-4 at 5. 2 kelvin.

Helium-3 has less than one-half of the density when it is at its boiling point: 5. 9 gram per liter compared to the 12. 5 gram perliter of helium-4 -- at a pressure of one atmosphere.

Helium-3 propulsion is a proposed method of spacecraft propulsion that uses the fusion of helium-3 atoms as a power source.

`` That is, if we can be sure this is Colcord's money '' --

It'll probably be at least an hour or two before I can check back with you.

Even as I said it I realized that an education can be invaluable.

Within their confines, moreover, technological and industrial growth has proceeded at an accelerated pace, thus increasing the cornucopia from which material wants can be satisfied.

And no messages can be transmitted on these circuits until senders and receivers authenticate in advance, by special codes, that the messages actually come from their purported sources.

Additional codes can be used to challenge and counterchallenge the authentications.

Nobody can be absolutely certain of the answers.

All can be connected with the gold circuit from their homes.

The box is internally wired so the door can never be opened without setting off a screeching klaxon ( `` It's real obnoxious '' ).

Unless all gadgets are properly operated -- and the wires and seals from the handles removed first -- no damage can be done.

I do not know if such a way of life can come to be a self-conscious challenge, but I suspect that it can.

As his disciples boast, even though his emphasis is elsewhere, Faulkner does show his awareness of the changing order of the South quite keenly, as can be proven by a quick recalling of his Sartoris and Snopes families.

An order can be chanced rather than chosen, and this approach produces an experience that is `` free and discovered rather than bound and remembered ''.

And any sequence can not only change its positions in the work but can even be eliminated from it altogether.

When it comes to this, I shall prefer emigrating to some country where they make no pretence of loving liberty -- to Russia, for instance, where despotism can be taken pure, without the base alloy of hypocrisy '' ( His emphasis )

Something of this can be learned from `` The Way To The Churchyard '' ( 1901 ), an anecdote about an old failure whose fit of anger at a passing cyclist causes him to die of a stroke or seizure.

Similarly experience itself can be conventionalized so that people react to certain preconceived clues for behavior without awareness of the vitality of their experiential field.

When words can be used in a more fresh and primitive way so that they strike with the force of sights and sounds, when tones of sound and colors of paint and the carven shape all strike the sensibilities with an undeniable force of data in and of themselves, compelling the observer into an attitude of attention, all this imitates the way experience itself in its deepest character strikes upon the door of consciousness and clamors for entrance.

it can be changed ; ;

You've already sent your daughter to Miss X's select academy for girls and your son to Mr. Y's select academy for boys, and you can be as liberal as you please with strict impunity.

In scope and power it can only be compared to Tolstoy's War And Peace.

However, for convenience we will stick to the idea that information can be classified according to Table 1.

Since the hazards of poor communication are so great, p can be justified as a habitable site only on the basis of unusual productivity such as is made available by a waterfall for milling purposes, a mine, or a sugar maple camp.
