    Notes: It is shown that a model of growth disorder, describing the way in which substitutional disorder can be introduced into binary solid solutions at growth, exhibits a phase transition. In a particular case it is shown that the distribution in 2D sections of the crystal corresponds to the simple pair-interaction Ising model on a triangular lattice.

    Notes: The following corrections should be made in Welberry & Miller [Acta Cryst. (1978). A34, 120-123]. 1. Equation (2) on p. 121 should read: E(σ) = - \sum_{{\rm all_{sites}}} σi,j,k [J(σi - 1, j, k + 1 + σ i,j + 1, k - 1 + σi + 1 j - 1, k) + K (σi - 1, j,k + σi,j - 1,k + σi,j,k - 1) + L(σi - 1, j,kσi,j - 1, kσi,j,k - 1)]. 2. The expression for J on p. 121 should be J = 1/8 In [a(1 - a)/b(1 - b)]. 3. In the second paragraph of the second column on p. 121 'J and - K' should be replaced by 'K and -J'. All information is given in the Abstract.

    Notes: The relationship between nearest-neighbour growth-disorder models and Ising models is described in detail. The growth model with only two-body interactions is shown to be equivalent, in section perpendicular to the growth direction, to a simple Ising model. Two approximate solutions for the growth model are compared with exact solutions of equivalent Ising models, where possible, and also with computer realizations; the behaviour of these approximate solutions is discussed.

    Notes: A series of squirrel monkeys received segmental femoral replacements in a study of the strength of the interface developed between the implant and bone. Implants were either made completely of bioglass-ceramic, or 316L stainless steel with a flame-prayed coating of bioglass. Fracture torque, energy at fracture, and shear stress at failure were compared to values obtained from a control group of pairs of tibias. Femurs containing bulk bioglassceramic implants showed about a 25% difference in strength compared to the opposite bone, while femurs containing flame-sprayed implants exhibited extremely low structural strength. While the strength of the metal-glass bond was very low (〈500 kgf/cm2), the bonebioglass bond was found to be at least as strong as the bioglass-ceramic, and at least 3/4 as strong as the host bone.
