Tom turned off the fan.

Tom turned on the fan.

I want an electric fan.

I turned off the fan.

And this was huge. The first one was the electric fan this was the 1890 electric fan.

I want an electric fan.

Here, A mouse has climbed into the blower behind the regulator rack, set blower to vibrating. Result no more mouse.

It was hot, so I turned on the fan.

Are you guys crazy? Turning the fan on when it's this cold?

So there's a strand that goes like this, goes along one helix and binds it jumps to another helix and comes back.

For a helix with thickness, see spring (math).

It will be difficult to sweep the room with the fan on!

I found a tractor fan, shock absorber, PVC pipes.

You'll be familiar with the double helix of DNA.

So Wilkins said he thought it was the helix.

It starts about 1890. And the electric fan was a big success.

One of the fan blades broke loose and shattered against the wall.

You mix them together and they make a rigid double helix.

X ray diagram, he thought was comparable with the helix.

It was powered by two turboprop aero engines and driven by propellers.

We want to look at individual strands and not think about the double helix.

The DNA double helix is unwound by the helicase activity of the enzyme.

And you can see a little bit of double helix forming there.

The helix and vortex can be viewed as a kind of three dimensional spiral.

The moment the fecal matter hits the rotating turbine, you can start shooting at people.

It is a genus of double stranded RNA virus in the family Reoviridae .

It's got a fan, it's got headlights for warmth, it's got door chimes for alarm it runs off a car battery.

I don't feel like doing anything, and I'm not getting up to turn on the fan.

These two long strands entwine like vines, in the shape of a double helix.

The double stranded structure of DNA provides a simple mechanism for DNA replication.

Adenoviruses (members of the family Adenoviridae) are medium sized (90 100 nm), nonenveloped (without an outer lipid bilayer) viruses with an icosahedral nucleocapsid containing a double stranded DNA genome.

DNA replication is the process of producing two identical replicas from one original DNA molecule.

Damage to DNA alters the spatial configuration of the helix, and such alterations can be detected by the cell.

The de Havilland DH.82 Tiger Moth is a 1930s biplane designed by Geoffrey de Havilland and was operated by the Royal Air Force (RAF) and others as a primary trainer.

In a double helix the direction of the nucleotides in one strand is opposite to their direction in the other strand the strands are antiparallel .

Sir Lawrence Bragg had been disappointed that Pauling had won the race to find the alpha helix structure of proteins.

Here, the strands turn about the helical axis in a left handed spiral, the opposite of the more common B form.

If the DNA is twisted in the direction of the helix, this is positive supercoiling, and the bases are held more tightly together.

I can raise an animal under conditions that would be equivalent to raising a baby under a moderately loud ceiling fan, in the presence of continuous noise.

A wet scrubber is basically a reaction tower equipped with a fan that extracts hot smoke stack gases from a power plant into the tower.

It's double stranded, it's a double helix, has the As, Ts, Cs and Gs that pair to hold the strands together.

Identifying the double helix In mid March 1953, using experimental data collected by Rosalind Franklin and Maurice Wilkins, Watson and Crick deduced the double helix structure of DNA.

The two strands of DNA in a double helix can therefore be pulled apart like a zipper, either by a mechanical force or high temperature.

A Lycoming O 235 C2A air cooled engine, rated at 115 hp (85.8 kW), drives a Sensenich Propeller model 72 CK 050, metallic fixed pitch twin bladed propeller.

These screw frigates , built first of wood and later of iron, continued to perform the traditional role of the frigate until late in the 19th century.
