Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...
Initially modern dropped ceilings were built using interlocking tiles and the only way to provide access for repair or inspection of the area above the tiles was by starting at the edge of the ceiling, or at a designated "key tile", and then removing contiguous tiles one at a time until the desired place of access was reached.
Tin ceiling in a private music room, Queensland, Australia, 1906. Tin ceilings were traditionally painted white to give the appearance of hand-carved or molded plaster. They were incorporated into residential living rooms and parlors as well as schools, hospitals and commercial businesses where painted tin was often used as wainscoting.
Each shoelace typically passes through a series of holes, eyelets, loops or hooks on either side of the shoe. Loosening the lacing allows the shoe to open wide enough for the foot to be inserted or removed. Tightening the lacing and tying off the ends secures the foot firmly within the shoe.
An aglet (/ ˈ æ ɡ l ə t / AG-lət) [1] or aiglet is a small sheath, often made of plastic or metal, attached at each end of a shoelace, a cord, or a drawstring. [2] An aglet keeps the fibers of the lace or cord from unraveling; its firmness and narrow profile make it easier to hold and easier to feed through eyelets, lugs, or other lacing ...
Concealed shoes have been discovered in several European countries, [6] as well as in North America [8] and Australia. [9] [10] Although deposits have been found throughout the United States they are concentrated in New England and the northeastern United States, the latter of which was first colonised by immigrants from the East Anglia region of England.
The ceiling before the restoration [c]. The preliminary experimentation for the modern restoration began in 1979. The restoration team comprised Gianluigi Colalucci, Maurizio Rossi, Piergiorgio Bonetti, and others, [6] who took as their guidelines the Rules for restoration of works of art as established in 1978 by Carlo Pietrangeli, director of the Vatican's Laboratory for the Restoration of ...
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.
