Egg-and-dart molding at the top of an Ionic capital at the Jefferson Memorial. Egg-and-dart, also known as egg-and-tongue, egg-and-anchor, or egg-and-star, [1] is an ornamental device adorning the fundamental quarter-round, convex ovolo profile of moulding, consisting of alternating details on the face of the ovolo—typically an egg-shaped object alternating with a V-shaped element [1] (e.g ...
A chevron (also spelled cheveron, especially in older documents) is a V-shaped mark or symbol, often inverted.The word is usually used in reference to a kind of fret in architecture, or to a badge or insignia used in military or police uniforms to indicate rank or length of service, or in heraldry and the designs of flags (see flag terminology).
A hand geometry reading device with pegs to control the placement of the hand. Angled mirror on the left reflects the side view image of the hand to the camera. A CCD camera is beneath the keypad to take the top view image of the hand and the mirror image. [2] Hand geometry is a biometric that identifies users from the shape of their hands ...
This includes mostly instruments which measure macroscopic properties of matter: In the fields of solid-state physics; in condensed matter physics which considers solids, liquids, and in-betweens exhibiting for example viscoelastic behavior; and furthermore, in fluid mechanics, where liquids, gases, plasmas, and in-betweens like supercritical ...
There are several variants of bending, where the most common is AX 2 E 2 where two covalent bonds and two lone pairs of the central atom (A) form a complete 8-electron shell. They have central angles from 104° to 109.5°, where the latter is consistent with a simplistic theory which predicts the tetrahedral symmetry of four sp 3 hybridised ...
Eurasian cranes in a V formation (video) Birds flying in V formation. A V formation is a symmetric V- or chevron-shaped flight formation.In nature, it occurs among geese, swans, ducks, and other migratory birds, improving their energy efficiency, while in human aviation, it is used mostly in military aviation, air shows, and occasionally commercial aviation.
A pair of woolen leggings found in the permafrost of the Italian-Austrian Alps have a 2:2 herringbone weave, dating to 800 to 500 BC. [6] A dark blue cloth with a 2:2 herringbone weave was found at Murabba'at Cave in Israel, from the Roman period. [6] [7] A textile with a 2:2 herringbone weave was found at Pompeii, from 79 AD. [6]
