The density of quartz is around 2.65 g/cm 3 but the dry bulk density of a soil can be less than half that value. Most soils have a dry bulk density between 1.0 and 1.6 g/cm 3 but organic soil and some porous clays may have a dry bulk density well below 1 g/cm 3.
These terms refer to the quality that the permeability value in question is an intensive property of the medium, not a spatial average of a heterogeneous block of material equation 2.28 [clarification needed] [further explanation needed]; and that it is a function of the material structure only (and not of the fluid).
The soil bulk density of cultivated loam is about 1.1 to 1.4 g/cm 3 (for comparison water is 1.0 g/cm 3). [48] Contrary to particle density, soil bulk density is highly variable for a given soil, with a strong causal relationship with soil biological activity and management strategies. [49]
[1] [2] While the circle has a relatively low maximum packing density, it does not have the lowest possible, even among centrally-symmetric convex shapes: the smoothed octagon has a packing density of about 0.902414, the smallest known for centrally-symmetric convex shapes and conjectured to be the smallest possible.

Then, [3] with respect to the usual Euclidean norm on , the 2-Wasserstein distance between and is (,) = ‖ ‖ + (+ ()). where denotes the principal square root of . Note that the second term (involving the trace) is precisely the (unnormalised) Bures metric between C 1 {\displaystyle C_{1}} and C 2 {\displaystyle C_{2}} .
His first novel, "Net een wenner" (Only One Winner) was published in 2005. [6] Badenhorst is married and has two children, Dirk (born 12 July 2004) and Suzanne (born 28 May 2007). He has Asperger syndrome [1] and campaigns for public awareness of the condition. [7]
The excluded volume of particles (the volume excluded to the centers of other particles due to the presence of one) is a key parameter in such descriptions,; [2] [3] the distance of closest approach is required to calculate the excluded volume. The excluded volume for identical spheres is just four times the volume of one sphere.
We want to calculate probability distribution function of distance to the nearest neighbor (NN) particle. (The problem was first considered by Paul Hertz; [1] for a modern derivation see, e.g.,. [2]) Let us assume particles inside a sphere having volume , so that = /. Note that since the particles in the ideal gas are non-interacting, the ...
