What is the difference between a helix and a double helix? The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing bya translation along the axis...
Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be approximately 1000 times bigger (about 10 μm). See how cells compare along a relative scale axis with other molecules, tissues, and ...

a collection of helical gears has a similar angle, but the helix hand is on the other side. When the reference of a part of the gear is within the standard form. the gear hobbing tool and hobbing machine would make helical gears by tilting the hobbing instrument. Thanks to the twist ...
The plate heat exchanger was introduced in the 1920s and applied to the food industry. The heat exchanger, which is made of plate tube, is compact and heat transfer, so it develops in various forms. In the early 1930s, Sweden made its first helix heat exchanger. The British brazing metho...
An advanced persistent threat (APT) is a sophisticated, sustained cyberattack in which an intruder goes undetected in a network to steal sensitive data.
The IPS and TN monitors' main difference is in how the two polarizers are positioned in relation to one another and the shape of the crystals in the liquid-crystal layer. In a TN monitor, the polarizers are perpendicular to one another and rely on the helix-shaped liquid crystals to "twis...
