This cushion is intended to improve safety when compared to earlier artificial surfaces and allows players to plant and pivot as if they were playing on a grass field. [7] Each square foot of turf contains about 3 kg (7 lb) of sand and 1.5 kg (3 lb) of cryogenic rubber. FieldTurf does not use shock-absorbency pads below its infill.

Artificial turf is a surface of synthetic fibers made to look like natural grass, used in sports arenas, residential lawns and commercial applications that traditionally use grass.
AstroTurf is an American subsidiary of SportGroup that produces artificial turf for playing surfaces in sports. The original AstroTurf product was a short-pile synthetic turf invented in 1965 by Monsanto. [2] Since the early 2000s, AstroTurf has marketed taller pile systems that use infill materials to better replicate natural turf. [3]
In 1948, Robert D. Edwards and John Magee published Technical Analysis of Stock Trends which is widely considered to be one of the seminal works of the discipline. It is exclusively concerned with trend analysis and chart patterns and remains in use to the present.
The primary data set used in cost distance analysis is the cost raster, sometimes called the cost-of-passage surface, [9] the friction image, [8] the cost-rate field, or cost surface. In most implementations, this is a raster grid , in which the value of each cell represents the cost (i.e., expended resources, such as time, money, or energy) of ...
GrassMaster reinforces a natural grass pitch by vertically inserting 20 million polypropylene (PP) fibres into the soil equally spread over the entire playing field. The 20 cm (7.9 in) long PP fibres are injected by computer-controlled machines, 18 cm (7.1 in) deep so 2 cm (0.8 in) remains above the surface. [1]
Essentially the existing turf is removed to a depth of typically 40 mm turf and 110 mm of soil. The replacement turf is ideally purpose grown to ensure consistency and freedom from weeds. A pitch can usually be returfed within four days and would typically involve removing and relaying 400 cubic metres of turf and soil.
The cost breakdown analysis is a popular cost reduction strategy and a viable opportunity for businesses. [1] [2] [3] The price of a product or service is defined as cost plus profit, whereas cost can be broken down further into direct cost and indirect cost. [1] As a business has virtually no influence on indirect cost, a cost reduction ...
