Critical ionization velocity The critical ionization velocity is the relative velocity between an ionized plasma and a neutral gas, above which a runaway ionization process takes place.

The critical ionization process is a quite general mechanism for the conversion of the kinetic energy of a rapidly streaming gas into ionization and plasma thermal energy.

A dorsal neural tube.

The degree of plasma ionization is determined by the electron temperature relative to the ionization energy (and more weakly by the density), in a relationship called the Saha equation.

That's a fluorescent tube refined.

These are called tube worms.

And these are made of this kind of tube electricity tube, we call it in Holland.

Please buy a tube of toothpaste.

The tube there's hollow, about paper thin.

This is called a cycle valve tube.

She recorded this message on You Tube.

The tube was shattered by the explosion.

The tube was shattered by the explosion.

Every seat in this tube is taken.

The mast is in the luff tube.

Mercury was added to the tube, trapping a fixed quantity of air in the short, sealed end of the tube.

It's victimless. It's meat from a test tube.

He squeezed the toothpaste out of a tube.

You can't put toothpaste back in the tube.

The other tube then released the fake blood.

Very high temperatures are usually needed to sustain ionization, which is a defining feature of a plasma.

Or, not so coincidentally, like a tube like this.

The length of the tube determines the fundamental frequency.

A tube shaped bag is open at both ends.

I only take the tube in NY, Paris and London!

It is widely used in commercial ionization chamber smoke detectors, as well as in neutron sources and industrial gauges.

The little hole in the middle, we'll come to a bit later, but that's for the pollen tube to come out later on. A very tiny tube.

The stellar temperature will determine the rate of ionization of various elements, resulting in characteristic absorption lines in the spectrum.

In chemistry, the ionization energy is typically specified as a molar quantity (molar ionization energy or enthalpy) and is reported in units of kJ mol or kcal mol (the amount of energy it takes for all the atoms in a mole to lose one electron each).

John Fleming invented the first radio tube, the diode, in 1904.

1978 Louise Brown, the world's first test tube baby is born.

In T8 lamps this is in the center of the tube.

They used a tube design, and some had reverb and tremolo.

The nucleus of the tube cell has meanwhile passed into the tube, as does also the generative nucleus, which divides (if it hasn't already) to form two sperm cells.

If you look at this, just the tube, it is quite bright.

1882) 1961 Lee De Forest, American inventor, invented the audion tube (b.

The length of the tube is reported to reach about four metres.

Along the way, the project absorbed its earlier British counterpart, Tube Alloys.

Native tube files may be in .tub, .psp, .pspimage, and .psptube formats.

Now, to do that, we need to be able to bring a camera and instruments in together through one small tube, like that tube you saw in the laparoscopy video.

Some of the heavier noble gases, however, have ionization potentials small enough to be comparable to those of other elements and molecules.

At these temperatures, well above typical ionization energies (13.6 eV in the hydrogen case), the fusion reactants exist in a plasma state.

The BBC has a You Tube channel , would anyone ever fathom the idea of you tube suspending the BBC, because of them showing graphic images from Abu Ghu raib for instance?

It'll approximate that shape. We do this for real in the test tube.
