A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.

The Building Research Establishment is owned by the BRE Trust, a registered charity that works to support research and education in the built environment.All of the profits accrued by BRE are passed to the Trust and are used to fund new research and education programmes designed to meet the Trust's goal of promoting safety and sustainability.
The B recognition element (BRE) is a DNA sequence found in the promoter region of most [clarification needed] genes in eukaryotes and Archaea. [1] [2] The BRE is a cis-regulatory element that is found immediately near TATA box, and consists of 7 nucleotides. There are two sets of BREs: one (BREu) found immediately upstream of the TATA box, with ...
In two dimensional square lattice percolation is defined as follows. A site is "occupied" with probability p or "empty" (in which case its edges are removed) with probability 1 – p; the corresponding problem is called site percolation, see Fig. 2. Percolation typically exhibits universality.
Percolation is the study of connectivity in random systems, such as electrical conductivity in random conductor/insulator systems, fluid flow in porous media, gelation in polymer systems, etc. [1] At a critical fraction of connectivity or porosity, long-range connectivity can take place, leading to long-range flow.
BRE, the protein product of the BRE (gene), is a core component of the deubiquitin complex BRCA1-A. [8] Other core components of the BRCA1-A complex are the BRCC36 protein (BRCC3 gene), MERIT40 protein (BABAM1 gene), and RAP80 protein (UIMC1 gene). [8]
The Cardington Fire Tests were a series of large-scale fire tests conducted in real structures (wood, steel-concrete composite, and concrete) at the BRE Cardington facility near Cardington, Bedfordshire, England, during the mid-1990s. After the tests, extensive computational and analytical studies of the behaviour of steel-framed composite ...
