The average. deviation of the routine axial plane from the anatomic axial plane was 5.0Â° abduction (SD =. 2.3Â°). The simplest correction method reduced the mean discrepancy in the observed TT-TG. distance by 68% and 72% in simulated femoral abduction and adduction, respectively.
The sand used to amend some soil is what's called builders sand...you can find it at Home Depot and Lowes and probably other garden centers. It is coarse grain and will provide good drainage....play sand is very fine grain and will cause more troubles than you had before.
No, it often is dredged from the sea and is too salty. Use horticultural sand. The amount of salt in sand is not really going to be an issue. The reason for not using builders sand is that it is soft and clumps together which is what it is supposed to do when being used for path laying or mortar. To alter the condition of a clay soil you needd to add sharp sand.
