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.
This course-textured soil is comprised of sand particles between medium- and coarse-sized particles. Clayey or fine textured soil has clay particles that are also the smallest particles of the three types, and the physical properties of soil containing clay makes the soil gummy and sticky. Silt has moderate-sized particles and a smooth, flour-like texture. Loam soil consists of clay, silt and sand sized particles. Soil texture can also be identified by feel; clay is sticky, silt is smooth and sand is gritty.
