Trachoma is an infection of the eye due to dirt getting into your eye. Multiple infections of trachoma can leave you permanently blind.

We need flour, sugar and eggs to make this cake.

Probably you are allergic to pollen or dust.

Both projects use the short wavelength spectrometer and deal with the interaction between pulsation, atmospheric structure and dust formation.

Dust is generally formed by mechanical processes.

The terms dust , mist and vapour are defined as follows

On Galileo pictures, they appeared as conspicuous Earth sized dark spots in visual and UV light.

Dusts and mists generally have sizes ranging from less than 1 to about 100 µm.

you know.

I tried to get you some sand dabs. No sand dabs, huh? No sand dabs.

The impacts of the Shoemaker Levy 9 fragments on Jupiter caused the formation of micron sized dust particles.

Oily Dirt

Sand

The little dust particle will again, reflect the light, and we realize the existence of light.

Dust means solid particles of a substance or mixture suspended in a gas (usually air)

And it isn't just bright flowers that have pollen it's also trees and grasses.

Without any flash powder, you gotta get this guy to freeze for a couple of seconds.

It takes a pile of loose sand and it creates sandstone out of it.

Lights and dust, as if they're digging themselves out.

To return in prayer to all lips Oh, that is life

In sandpaper, bone glue is actually the glue between the sand and the paper.

The only light came through two small filthy windows.

Add their clouds and dust, it amounts to no more than our twilight.

An International Conference of Astronomers will be held at the University of the Witwatersrand from 22 to 26 January 1996 to focus on changing perceptions of the morphology, dust content and dust to gas ratios of galaxies.

The windows were closed... and the sunshine coming in through the venetian blinds... showed up the dust in the air.

In the cities they work with sand, gravel and other aggregates that go into construction materials.

There is no sugar left in the pot.

Depleted uranium left radioactive poison dust which was easily inhaled or ingested and which caused many illnesses and genetic deformities.

You can see the little pink cursor moving along, representing our position.

I've never seen those before.

I spray it on for about three or four days, it drips to hell, but it allows me a really, really nice gentle sanding surface and I can get it glass smooth.

And most controversially, it means the tar sands.

Tar Sands are found mainly in Canada.

There's probably no gravel there anyway.

It is stopping the tar sands.

A dust storm similar to the Earth's dust is often formed in the Mars in the summer, which will lead to a sharp decline in solar energy. So a sleep mode must be designed for the Mars rover and let it wait patiently until the disappearance of dust storms.

Three million people die every year in cities due to bad air, and almost all particulate pollution on this planet is produced by transportation devices, particularly sitting in cities.

Dust thou art, and to dust thou shalt return.

If we'd just leave the blinds shut like we do the rest of the year, nobody'd see the dust!

Sixth Conference on Heavy Crude and Tar Sands

Oil sand is not a long term solution.

Yes, sir, the gravel's all been scattered!
