Taxonomy is the science of classifying organisms. The system currently used by taxonomists is called the Linnaean taxonomic system, in honor of Swedish biologist Carolus Linnaeus (1707 â 1778). The Linnaean system breaks down organisms into seven major divisions, called taxa (singular: taxon).
When used by the Chinese to protect their land, this section of the wall has had many guards to defend China's capita, Beijing. Made of stone and bricks from the hills, this portion of the Great Wall is 7.8 meters (25.6 ft) high and 5 meters (16.4 ft) wide.
Gabion wall base width relative to wall height base width of a gabion gravity retaining wall is related to the height of wall so as the wall height increases the base becomes wider to ensure structural stability. Below is a suggested diagram to illustrate a starting point for design. A typical conservative value of base width = 2/3 wall height. *** A stability analysis may determine that the gabion gravity retaining wall base width be less than or greater than 1/2 - 2/3 wall height.
