At the composition 21 at.% Ga, the congruently ordered B2 phase undergoes further B2 → DO3 congruent ordering, which is followed by decomposition into an equilibrium mixture of the bcc and DO3 phases.
It is found that the precipitation of δ′ occurs either by a congruent ordering process followed by decomposition, or by a non-classical nucleation mechanism which requires critical fluctuations of both composition and order parameter, except in a narrow range of compositions near the equilibrium phase boundary of the disordered phase, where classical nucleation theory seems to be applicable.
It is shown that the initial stage of equilibration of the compositionally homogeneous bcc solid solution with 19 at.% Ga results in bcc → B2 congruent ordering followed by a precipitation of Ga-rich B2 particles, which eventually transform to particles of the DO3 phase.
The results can be explained by the coherence principle which postulates that information from different media should be congruent in order to foster process fluency.
Halliday & Matthiessen (2014: 715) insist that metaphorical expressions that appear as nominalisations must have a congruent equivalent in order to identify the process in the clause.
The only previously known examples of Steiner triple systems of order congruent to 1(mod6) without almost parallel classes were the projective triple systems of order 2n−1 with n odd, and 2 of the 11,084,874,829 Steiner triple systems of order 19.
As a corollary any Eisenstein Jacobi graph with order congruent to 1 modulo 6 and underlying Eisenstein Jacobi integer not an associate of a real integer, is a cover of a 6-valent first-kind Frobenius circulant.
Normal menisci protect the joint cartilage by distributing loads over a broad and congruent area in order to guarantee stability and correct movements of the joint surfaces, lubricating and nourishing them [1, 2, 3, 4]; moreover they provide propioceptive information [5].
Exclusion of these out-groups produced an apyrase gene tree with a species branching order congruent with that for the conserved EF-1α gene, except for the failure to group the members of the P. perniciosus complex, P. perniciosus and Phlebotomus tobbi.
Our finding is in accordance with the previous study of peach BAC sequences that the segments with a gene order congruent with Arabidopsis were short in any peach region studied and the corresponding segments were found in diverse locations in the Arabidopsis genome [ 24].
