In 1855, the first iron propeller driven ships were ordered from England.

World's first bamboo bike with folding handlebars.

This motor drives the motion of the filament, which acts as a propeller.

Problems with propeller fouling, blocked intake pipes and damaged drive shafts have been reported.

and two doors of fir wood the two leaves of the one door were folding, and the two leaves of the other door were folding.

And despite the aerodynamic interactions of these propeller blades, they're able to maintain stable flight.

The Propeller Banksia ( Banksia candolleana ) is a species of shrub in the plant genus Banksia .

And the two doors were of fir tree the two leaves of the one door were folding, and the two leaves of the other door were folding.

A propeller is a type of fan that transmits power by converting rotational motion into thrust.

The fastest grid computing system is the distributed computing project Folding home.

(Originally determined by folding a printer's sheet of paper twice to form four leaves.

A little sleep, a little slumber, a little folding of the hands to sleep

a little sleep, a little slumber, a little folding of the hands to sleep

Yet a little sleep, a little slumber, a little folding of the hands to sleep

Yet a little sleep, a little slumber, a little folding of the hands to sleep

And the interesting thing is that if you change the sequence, you change the three dimensional folding.

It can be used to identify folding and faulting, and to search for oil and gas fields.

Newspapers in most advanced countries are struggling or folding, and investigative reporting is often the first thing they cut.

And that instruction set, from the brain to every other part of the body look at the complexity of the folding.

Parallel computing is used in a wide range of fields, from bioinformatics (protein folding and sequence analysis) to economics (mathematical finance).

And like this magnificent origami, cells are developing at one million cells per second at four weeks, as it's just folding on itself.

But, rather than folding their cards, European leaders doubled down. They understand that their gamble will be immensely costly if it proves wrong.

Rugae is a term used in anatomy that refers to a series of ridges produced by folding of the wall of an organ.

Neurulation refers to this folding process whereby the neural plate is transformed into the neural tube, and this takes place during the fourth week.

Initially, many different designs were considered, including an unconventional project with two main rotors, placed with engines on tips of wings (in perpendicular layout), and with an additional pusher propeller on the tail.

Poet Rives does 8 minutes of lyrical origami, folding history into a series of coincidences surrounding that most surreal of hours, 4 o'clock in the morning.

People have been struggling for years to try and design a very fast rotating boat propeller that doesn't cavitate and literally wear away the metal and put holes in it, just like these pictures show.

And if folding a single praying mantis from a single uncut square wasn't interesting enough, then you could do two praying mantises from a single uncut square.

When the virus comes in contact with the membrane of a host cell, it binds to a receptor site and triggers a folding in of the membrane.

The complexities of the wing folding mechanism, as well as the mechanical operation of the wings in flight (indirect flight muscles), are such that it clearly indicates the Neoptera are a monophyletic lineage.

In 2007, Paul Rothemund gave TED a short summary of his specialty, DNA folding. Now he lays out in clear, abundant detail the immense promise of this field to create tiny machines that assemble themselves.

And rather than go into statistics and trends, and tell you about all the orchestras that are closing, and the record companies that are folding, I thought we should do an experiment tonight an experiment.

It initially started off with me stacking these things, bunches of them, and then playing with the sense of space, of filling in the space. And then it started changing, and become folding on themselves.

So this art has been around for hundreds of years, and you would think something that's been around that long so restrictive, folding only everything that could be done has been done a long time ago.

Now, we can take this form and use the same process to generate three dimensional structures, but rather than folding things by hand, we'll bring the structure into the computer, and code it as an algorithm.

Protein structure prediction is the prediction of the three dimensional structure of a protein from its amino acid sequence that is, the prediction of its folding and its secondary, tertiary, and quaternary structure from its primary structure.

We can plot the planarity of the surfaces, their curvature, how radial they are all information that may not be instantly visible to you, but that we can bring out, that we can articulate, and that we can use to control the folding.

He went from being alive and passionate at Stage One remember, Life sucks, despairing hostility, I will do whatever it takes to survive to walking into a Boys and Girls Club, folding his arms, sitting down in a chair, and saying, Wow. My life really sucks.

These lenses use some form of the cassegrain design which greatly reduces the physical length of the optical assembly, partly by folding the optical path, but mostly through the telephoto effect of the convex secondary mirror which multiplies the focal length many times (up to 4 to 5 times).

They serve as a sign that the children who make them and those who visit the statue desire a world without nuclear war, having been tied to the statue by the story that Sadako died from radiation induced leukemia after folding just under a thousand cranes, wishing for world peace.

They know how to bring it back, and they know how to bring it back because they have demystified one big myth, which is the myth of spontaneity, which is that it's just going to fall from heaven while you're folding the laundry like a deus ex machina, and in fact they understood that whatever is going to just happen in a long term relationship already has.
