Tennis court project

Rubber concrete placed in all the test sites previously mentioned was mixed by the process described next, excluding the rubber concrete tennis court project. Fresh concrete was first mixed without crumb rubber in a batch plant, and then hauled to the job site by a concrete truck. Crumb rubber was then added to the truck on the job site, and a remix was performed. To make the crumb rubber disperse uniformly in a concrete truck, a per-metre based empirical formula of the re-mixing time needed for a regular concrete truck (about 7.6 m capacity) is proposed here that states ... 

The mucosal layer, comprising the lumenal surface of the small intestine, is responsible for the digestive and absorptive functions of the small intestine. The mucosal surface area is much larger than predicted for a simple cylinder. Circular folds account for this amplification. The mucosal surface area is extended further by fingerlike projections called villi and depressions called crypts. The villi are 0.5-1.0 mm in height. Each villus and crypt is lined by epithelial cells that are covered with many closely packed microvilli that project into the intestinal lumen. If the small intestine is viewed as a simple cylinder, its mucosal surface area would be on the order of half of a square meter. However, in reality, the mucosal surface area of the small intestine is approximately 250 square meters, comparable with size of a tennis court.
