The main valve is turned off.

If it's circular, you make a spherical lens.

I have a straight line on my spherical surface.

for placing the Sun, not the Earth, at its centre.

And this is how you make a valve.

The resulting eye is a mixture of a simple eye within a compound eye.

Engineers ordered the valve closed and the countdown continued.

And once it's in the right spot, they remove the outer shell, and the heart valve, well, it gets this shape and at that moment it starts beating, instantly.

This explains the nearly spherical shape of the outer Oort cloud.

Between two spherical waves A point source produces a spherical wave.

This is actually a heart valve, which we engineered.

Many of these new trombone valve designs have enjoyed great success on the market, but the standard rotary valve remains the most common for trombone valve attachments.

Does the color of the valve matter? What matters here?

In practice, the language barrier impairs this safety valve.

He was born with an incompletely formed heart valve.

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

Now that's a left ventricle pushing blood up through the aortic valve you can see two of the leaflets of the aortic valve working there up into the ascending aorta.

The first valve lowers the instrument's pitch by a whole step (2 semitones), the second valve by a half step (1 semitone), and the third valve by one and a half steps (3 semitones).

And the way you engineer this heart valve is the same strategy.

Today we don't need one million light bulbs to create a spherical display.

The mass of Ceres is sufficient to give it a nearly spherical shape in hydrostatic equilibrium.

It has a funny trilobal shape at the bottom, which contains the aortic valve.

The number of neurons in the cerebellum is related to the number of neurons in the neocortex.

He proposed using a spherical configuration instead of the cylindrical one that Neddermeyer was working on.

Gustaf Dalén founded AGA, and received the Nobel Prize for his sun valve.

For example, water striders use surface tension to walk on the surface of a pond.

The nebula forms a roughly spherical cloud that peaks in density near the core.

The control unit simply uses a butterfly valve for the air, which is linked by a mechanical linkage to a rotary valve for the fuel.

The household microwave oven uses a magnetron tube to efficiently generate hundreds of watts of microwave power.

The ileum follows the duodenum and jejunum and is separated from the cecum by the ileocecal valve (ICV).

Rotary valve engines can be tailored to deliver power over a wider speed range or higher power over a narrower speed range than either piston port or reed valve engine.

Spherical spiral A spherical spiral (rhumb line or loxodrome, left picture) is the curve on a sphere traced by a ship traveling from one pole to the other while keeping a fixed angle (unequal to 0 and to 90 ) with respect to the meridians of longitude, i.e.

The NATO standard probe system incorporates shear rivets that attach the refueling valve to the end of the probe.

The virus particle is 80 120 nanometers in diameter and usually roughly spherical, although filamentous forms can occur.

So this is actually a Dutch company, so I called them up, and I asked, Can I borrow a heart valve from you?

However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space.

An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile.

Grid variations A variation of the control grid is to produce the helix with a variable pitch.

The aortic valve is one of the two semilunar valves of the heart, the other being the pulmonary valve.

And as I looked at it, it kind of tucked its arms under it, raised into a spherical shape and turned chocolate brown with two white stripes.

It is part of the collection of the Smithsonian Institution in Washington, D.C. and of New York's Museum of Modern Art.

We take the scaffold, we seed it with cells, and you can now see here, the valve leaflets opening and closing.

So, the most beautiful thing I found at least what I think is the most beautiful in the book, is this heart valve.

Great and then I didn't hear from them for weeks, so I called, and I asked, What's going on with the heart valve?

Even trips to the dentist require that you take antibiotics, in case you get an internal infection on the valve.
