This room has fine ventilation.

This is called a cycle valve tube.

And this is how you make a valve.

This is actually a heart valve, which we engineered.

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

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.

We blocked them off at night so that they got no ventilation.

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

This is the natural posture of a man sitting, squatting for ventilation purposes.

You see the sunbeams coming from the ventilation ducts and the train approaching.

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.

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

impressed so many tourists. The toilet has ventilation all year around without a peculiar smell.

Buildings are colonized by airborne microbes that enter through windows and through mechanical ventilation systems.

(a) Air Monitoring discharge post filtration, using probes inserted into the ventilation systems within the complex

The grooves become the kind of green lungs which give views, which give light, ventilation, make the building fresher.

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

People bring their own cooker, he attaches a valve and a steam pipe, and now he gives you espresso coffee.

(6) having an actually measured surface and underground engineering comparison drawing, a mining and excavation plan and a ventilation system drawing

How to take care in five easy steps first of all, you can use natural ventilation. You can use body breath.

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

Its unique cool flow valve can efficiently discharge hot and damp exhaled breath from inside the respirator, allowing easier breathing for users.

Likewise, if you have the artificial valve option, you're committed to antibiotic therapy whenever you have any intrusive medical treatment at all.

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

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

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?

The use of fuelwood for household cooking and heating can also cause health hazards and respiratory illness, especially in small spaces without proper ventilation.

He turned the wrong valve when he filled his cylinder he had 80 percent oxygen in his tank when he should have had 40.

The low tech bit is that it's literally a pig's heart valve mounted in the high tech bit, which is a memory metal casing.

They commissioned a group of their best scientists to investigate, and what they found was that all these tape drives were located near ventilation ducts.

And I realized that if I scaled them up, they would provide me with good spatial qualities, for ventilation, for thermal comfort, and for other things.

So you see the leaflets opening and closing of this heart valve that's currently being used experimentally to try to get it to further studies.

The fire disaster happened at about 10 00am and was put out at about 10 30am. It is the snifting valve inside that triggered the fire.

And they said, Well the director of the company decided not to let you borrow this heart valve, because want his product to be associated with pigs.

And some of these models so you take a bit of this cycle valve tube, you can put two matchsticks inside this, and you make a flexible joint.

And the fact that pig heart valves have lots of these on them is the reason that you can't transplant a pig heart valve into a person easily.

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.

We spend an extraordinary amount of time in buildings that are extremely controlled environments, like this building here environments that have mechanical ventilation systems that include filtering, heating and air conditioning.

If you look at the x axis of this graph, you'll see that what we commonly want to do which is keeping the outdoors out we accomplished that with mechanical ventilation.

We can see the same processes at work in terms of the Commerce Bank its dependence on natural ventilation, the way that you can model those gardens, the way they spiral around.

Their ventilation of disappointment should not, however, be construed as the absence of a mandate or as a diminished mandate for the General Assembly, through its First Committee, to discuss disarmament issues.

The security risk and blast assessment study found that the security measures incorporated in the final design, including the repositioning of the building, glazing specifications for the facade and ventilation features, were appropriate and sufficient.

But many other single currency areas, including the US, display similar divergence. It should also be obvious that, in the absence of currency markets to act as a valve for economic and financial pressures, economic volatility may increase.

(3) Appropriate facilities shall be made available for disinfection, changing clothes, toilet, natural and artificial light, ventilation, prevention of spoilage, protection against dust, elimination of flies and rodents, washing of equipment, sewage discharge and the containment of garbage and other wastes

We looked at rooms that were naturally ventilated, where the hospital let us turn off the mechanical ventilation in a wing of the building and pry open the windows that were no longer operable, but they made them operable for our study.
