Artificial turf with rubber crumb infill Side view of artificial turf Diagram of the structure of modern artificial turf Artificial turf square mats. 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.
Enviroboard is a paper-like or cardboard-like construction and packaging material, generally manufactured using compressed, ecologically safe, agricultural material. Most often this means employing the use of high-cellulose waste fibres, such as the post-harvest straw of rice, barley, wheat, and elephant grass or alternatively, a more urban waste stream such as newspaper fibre.
[3] The first practical use of the Marston mat was during the Carolina Maneuvers, a series of United States Army exercises held in November 1941. A 3,000-by-150-foot (914 by 46 m) airstrip was constructed of the material near Camp Mackall in the area of Marston, North Carolina. Installation of the airstrip was completed in 11 days.
A simpler method of making panels from leaves is called pawid, which is simply thatching. It predominantly uses nipa palm leaves, and is the origin of the name of the nipa hut. But it can also use other materials like coconut leaves, anahaw leaves, and even cogon grass. They are made by simply folding the leaves once around a split bamboo stick ...
A more recent design is the installation of a roof deck with foil-backed foam along with a second deck that is air-gapped away from the foil-backed foam to allow air to flow vertically to a ventilation outlet at the peak of the roof—it is a double-deck design with an air gap. This design improves efficiency. [13]
PV panels mounted on roof Workers install residential rooftop solar panels. The solar array of a PV system can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle.
Paspalum notatum, known commonly as bahiagrass, common bahia, and Pensacola bahia, is a tropical to subtropical perennial grass (family Poaceae).It is known for its prominent V-shaped inflorescence consisting of two spike-like racemes containing multiple tiny spikelets, each about 2.8–3.5 millimetres (0.11–0.14 in) long.
The PCB of a quartz watch. The clock IC is under the drop of black epoxy. Chip on board (COB) is a method of circuit board manufacturing in which integrated circuits (e.g. microprocessors) are attached (wired, bonded directly) to a printed circuit board, and covered by a blob of epoxy. [1]
