Also in 1906, Robert von Lieben and Lee De Forest independently developed the amplifier tube, called the triode.

Furthermore, MIT has developed the foldable electric CityCar, four of which can fit into a conventional parking space.

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

A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger.

Even here, there is another grower, you see, very interested in the bugs, the bad ones and the good ones, wearing this magnifier already on her head, just walking safely in her crop.

So now I'm not specifying a single ratio anymore to fold it, but instead I'm establishing a rule, I'm establishing a link between a property of a surface and how that surface is folded.
