Models of the lunar density distribution are presented that are consistent with all available data on the physical properties of the Moon. It is found that Nike Air Yeezy 2 For Sale Uk the density profile is very sensitive to changes in moment of inertia and surface density, and largely insensitive to changes in the central density. From the gravity field and surface composition of the Moon, a moment between 0.39 and 0.40 and a surface density near 3.1 g/cm3 is Air Yeezy 2 Uk inferred. The central density (with no high density core) is about 3.7 g/cm3 if the Moon is chemically homogeneous, 3.5 g/cm3 if differentiation is assumed. A proper k  -coloring C1,C2,…,CkC1,C2,…,Ck of a graph G   is called strong   if, for every vertex u∈V(G)u∈V(G), Nike Yeezy 2 there exists an index i∈{1,2,…,k}i∈{1,2,…,k} such that u   is adjacent to every vertex Cheap Nike Air Force 1 of CiCi. We consider classes SCOLOR(k)SCOLOR(k) of strongly k  -colorable graphs and show that the recognition problem of SCOLOR(k)SCOLOR(k) is NP-complete for every k⩾4k⩾4, but it is polynomial-time solvable for k=3k=3. We give a characterization of SCOLOR(3)SCOLOR(3) in terms of forbidden induced subgraphs. Finally, we solve the problem of uniqueness of a strong 3-coloring.
