lagging

[′lag·iŋ]
(civil engineering)
Horizontal wooden strips fastened across an arch under construction to transfer weight to the centering form.
Wooden members positioned vertically to prevent cave-ins in earthworking.
(cell and molecular biology)
Pertaining to chromosomes that show little or no movement during metaphase and anaphase of meiosis or mitosis.
(materials)
Asbestos and magnesia plaster that is used as a thermal insulation on process equipment and piping.

Lagging

 

a lumber product cut to size; produced from the side of a log by sawing. If the convex side of the lagging is not sawed through or is sawed through for less than half of its total length, the product is called side lagging; if the convex side is sawed through for more than half of its length, the product is called board lagging. Lagging is used to make scaffolding, centering, and support material.

lagging

1. Thermal insulation for pipes, tanks, ducts, etc.; sometimes block insulation, pre-shaped to conform to the curved surface.
2. The planking, consisting of narrow strips, extending from one rib of the centering of an arch or vault to another; provides direct support for the voussoirs until the arch or vault is closed in.
3. Boards which are joined, side by side, lining an excavation.
4. Horizontal members between soldier piles.
5. Wood strips that cover a wall.

lagging

i. A type of insulation around certain lubrication system lines to keep it from losing heat in the oil to outside air.
ii. In formation, an aircraft that is well behind its assigned position.

Firstly, Reverse Engineering is a reduced-form approach, which does not have the capacity to identify a dynamic lagging error structure.
Another method used to take care of the lagging problem in appraisal-based real estate returns is called the Repeated-Measures Regression (RMR).
It is argued that this setting has the flexibility to allow the lagging error to be influenced by a variety of variables.
However, most of the studies on the lagging problems of appraisal-based returns estimate focus on the data on the U.
Before Asarco installed the new pulley lagging, heavy rains and flash storms - or even the threat of them - forced the company to shut down their copper mine for four to eight hours a day, two to four times a week, for roughly four and a half months of the year.
An old diamond-groove rubber lagging covered the pulley's 72-inch-wide face.
Asarco engineers added 3 1/2 tons of conveyor counterweight to increase belt tension and replaced the existing rubber lagging with a softer grade, but the problem persisted.
The new lagging uses high-grade alumina ceramic tiles molded into a natural or flame-resistant rubber backing.
5 st to the counterweight and replacing 60-durometer rubber lagging with a softer 40-durometer variety, which might have had a better grip on the belt but neither was successful.
Gardner discussed the problem with one of the mine's belt distributors, National Belt Service (NBS), who suggested a new alternative to rubber lagging developed to improve conveyor productivity under even the most demanding operating conditions.
Employing a special ceramic-in-rubber design, Flexco Flex-Lag ceramic pulley lagging from Flexible Steel Lacing Co.
The cyclical turning points in the lagging index generally have occurred after those in aggregate economic activity.
