0 (the length of) a straight line drawn from side to side of a circle, passing through its centre/center -- diameter
Measure the diameter of the circle.
In opening up the torus, the non-circularity of the cross section is assumed small and decreasing to zero with increasing diameter of the torus.
Erodible fraction is defined as the percentage of soil mass < 0.84 mm diameter, and this parameter has been related to soil wind erodibility.
To obtain infested fruits, a third instar larva was placed into a small plastic dish (diameter 17 mm, height 11 mm).
A glass capsule of 280 -300 mm in diameter was placed in the center of it.
If lizards were on elevated perches, we recorded the diameter of the perch (cm) and height off the ground (m).
The seeds (diameter 1-2 mm) contain a peripheral embryo that forms a ring around the central perisperm.
Subsequently, saltation begins when particles move vertically into the air by a distance of the order of their diameter.
The diameter at entrance is 30 mm and diameter at tip is varied as 0, 3, 5, and 10 mm.
