Lichen sclerosus and lichen planus are fairly common, non cancerous skin conditions. They can affect different parts of the body, but commonly affect the vulva. When they affect the skin of the vulva, theyâre known as vulval LS or LP.
A gap-graded soil is a soil that has an excess or deficiency of certain particle sizes or a soil that has at least one particle size missing. An example of a gap-graded soil is one in which sand of the No. 10 and No. 40 sizes are missing, and all the other sizes are present.
Most gap graded soils have a coefficient of curvature outside the range. If we have introduced like a gap graded soil, some times an absence of intermediate particle sizes exists. So with this what happens is that, you know that particular type of soil is called gap graded soil or bimodal soil.
