Abstract
We consider 2‐factorizations of complete graphs that possess an automorphism group fixing k⩾0 vertices and acting sharply transitively on the others. We study the structures of such factorizations and consider the cases in which the group is either abelian or dihedral in some more details. Combining results of the first part of the paper with a result of D. Bryant, J Combin Des, 12 (2004), 147–155, we prove that the class of 2‐factorizations of complete graphs is universal. Namely each finite group is the full automorphism group of a 2‐factorization of the class. © 2009 Wiley Periodicals, Inc. J Combin Designs 17: 211‐228, 2009

## Abstract It is known that a necessary condition for the existence of a 1‐rotational 2‐factorization of the complete graph __K__~2__n__+1~ under the action of a group __G__ of order 2__n__ is that the involutions of __G__ are pairwise conjugate. Is this condition also sufficient? The complete ans
## Abstract The temperature dependence of the Debye‐Waller factors of vanadium and silicon in V~3~Si and that of the X‐ray Debye temperature are obtained from the integral intensities of X‐ray reflection measured at 11 temperatures ranging from 8 K to 293 K. It shown that the breaks on these curves
Measurements of (p, r, T ) at given temperatures and pressures in the compressed liquid phase for {xC2H5OH + (1x)H2O} with x = (0.1002, 0.2503, 0.4999, 0.7495, and 0.8904) were carried out with a metal-bellows variable volumometer along six isotherms between T = 320 K and T = 420 K at pressures from
A bellows volumometer has been used to obtain volume ratios relative to p = 0.1 MPa for each of the liquids pentan-2-one, hexan-2-one, and 4-methylpentan-2-one at the temperatures (278.15, 288.15, 298.14, 313.14, 323.14, and 338.13) K for pressures up to 386 MPa or close to the freezing pressure, wh
