Streptococcus bacteria is a genus of coccus, or spherelike, Gram-positive, chained bacteria belonging to the lactic acid bacteria (LAB) group.Individual streptococcus cells may be round or ovoid and all lack the enzyme catylase. Because these cells divide along a single plane, streptococci occur in pairs or in chains.hese 10 animal facts will amaze you.

Steel Sheet Piling. Steel sheet piles are long structural sections with a vertical interlocking system that creates a continuous wall. The walls are most often used to retain either soil or water. The ability of a sheet pile section to perform is dependent upon its geometry and the soils it is driven into. The pile transfers pressure from the high side of the wall to the soil in front of the wall. There are permanent and temporary applications. Permanent sheet piles remain in the ground and serve as permanent retaining structures. Temporary sheet piles are designed to provide safe access for construction, and are then removed. Hot rolled and cold formed are two primary methods of manufacturing sheet pile. While there are differences between these two methods, the most important distinction is the interlock.
Temporary formwork is a reusable formwork that is removed from around the concrete once it is set. It is generally made from timber, steel, plywood or plastic. Permanent formwork is formwork that stays in place and is never removed and an excellent example of this is Insulated Concrete Forms (ICFs).ICFs are made from a foam material (EPS â expanded polystyrene) that has a âhollowâ in the middle into which concrete is poured.ind Out More About Concrete Formwork.
