Exempel på hur du använder HELICAL i en mening

• He, James Watson, Rosalind Franklin, and Maurice Wilkins played crucial roles in deciphering the helical structure of the DNA molecule.
• The sound vibration waveforms are recorded as corresponding physical deviations of a helical or spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record".
• A rifle is a long-barreled firearm designed for accurate shooting and higher stopping power, with a barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall.
• 62 mm designation refers to the internal diameter of the barrel at the lands (the raised helical ridges in rifled gun barrels).
• Lunokhod 1 was equipped with a cone-shaped antenna, a highly directional helical antenna, four television cameras, and special extendable devices to test the lunar soil for soil density and mechanical properties.
• The ability of nucleobases to form base pairs and to stack one upon another leads directly to long-chain helical structures such as ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).
• Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy.
• Lunokhod 1 was equipped with a cone-shaped antenna, a highly directional helical antenna, four teleray spectrometer, an x-ray telescope, cosmic-ray detectors, and a laser retro-reflector (supplied by France) was also included.
• A six-story helical ramp extends along the main gallery's perimeter, under a central ceiling skylight.
• The Tyson turbine is a conical water turbine with helical blades emerging partway down from the apex gradually increasing in radial dimension and decreasing in pitch as they spiral towards the base of the cone.
• The helical coil of a solenoid does not necessarily need to revolve around a straight-line axis; for example, William Sturgeon's electromagnet of 1824 consisted of a solenoid bent into a horseshoe shape (similarly to an arc spring).
• Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices.
• To facilitate digital recording on existing Hi8 video cassettes the helical scan video head drum spins 2.
• Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium.
• It is observable in amorphous wires with helical domain structure, which can be obtained by twisting the wire, or annealing under twist.
• It acts on charged particles through Lorentz force and causes them to travel in helical paths whose radii are determined by the particles' charge-to-mass ratios and their velocities.
• To increase capacity, a third ring was built (only in the two curves and in the west grandstand) which rests on eleven support towers surrounded by helical ramps that allow access to the public.
• Chargaff's research would later help the Watson and Crick laboratory team to deduce the double helical structure of DNA.
• The piston was fitted with a vertical post at its rear which rode in a helical cam track in the bolt, rotating it at the end of its travel nearest the breech.
• Its cut is analogous to that of a lathe, except that it is (archetypally) linear instead of helical.
