| The two HC, a-helical domains are helically interwound, giving the molecules a long, rigid superhelical structure with 2 globular headpieces. |
|
| Bacterial cells are propelled by rotating, helically shaped locomotive organs called flagella. |
|
| Their proposed structure consisted of two polynucleotide chains helically wound about a common axis. |
|
| We descend, helically, and park under a horse chestnut near a flint wall, a house, a flint barn. |
|
| It is represented by stems, helically arranged and bifurcate fronds with two orders of pinnae and planate pinnules. |
|
| This is made of strips of pale larch wound helically to the sky. |
|
| Leaves are parallel veined and appear to be helically arranged. |
|
| The sealing is done by a lip on the elastomer ring that is pressed snugly around the shaft by a helically wound garter spring. |
|
| Bacterial flagella are helically shaped structures containing the protein flagellin. |
|
| This would be the case if the receive antenna were a loop, wideband dipole, log periodic, or a helically wound antenna in high-angle mode. |
|
| Type SL is helically wound from a formed strip of Electro-Galvanized steel. |
|
| It has been hypothesized that, in order for a single cell to shorten in such a unique fashion, the contractile proteins in smooth muscle are helically oriented within the muscle cell. |
|
| A propeller produces a helically shaped slipstream of accelerated air. |
|
| Vibration is reduced by the helically positioned cutting edges with free-cutting geometries and concentricity. |
|
| In the Late Triassic evolved bizarre heteromorphs with loosely coiled body chambers, such as Choristoceras, or with helically coiled whorls, such as Cochloceras. |
|
| Optical biaxial film, characterized in that it comprises an anisotropic material with a helically twisted structure and a uniform helix and reflects light of a wavelength of less than 400 nm. |
|
| It is generally thought that these jets are probably propelled by magnetic forces arising in the magnetic field lines that are helically twisted by the rotation of the disk and that are directed perpendicular to it. |
|
| Manufacturing requirements shall be in accordance with paragraph 8.3. above except that the over-wrap shall also include helically wound filaments. |
|
| His inventions ranged from surgical tools to metal alloys, from a floatation device to rescue disabled ships to a functioning helically driven airship that actually flew. |
|
| Due to the properties of the helically wound steel cable, turning the handwheel of the operator station simultaneously operates the valve station. |
