Cercle et Carré
Cercle et Carré (Circle and Square). A discussion and exhibition society for abstract artists formed in Paris in 1929 by the critic Michel
Seuphor and the painter Joaquín
Torres-García. They published a journal of the same name, of which three numbers appeared in 1929–30. The association held only one exhibition, at Galerie 23 in April 1930, but this has the distinction of being the first group exhibition ever devoted solely to abstract art; 46 artists showed work, including
Mondrian and
Vantongerloo but also such non-geometricians as
Kandinsky and
Schwitters. In 1931 Cercle et Carré was superseded by the larger and longer-lived
Abstraction-Création association, but it had a sequel in Uruguay: in 1935 Torres-Garcia formed an Asociación de Arte Constructivo in Montevideo and edited a journal
Círculo y Cuadrado, of which seven numbers appeared between 1936 and 1938.

Influence of temperature-dependent viscosity on the MHD Couette flow of dusty fluid with heat transfer.(magnetohydrodynamics )
Magazine article from: Differential Equations and Nonlinear Mechanics; 1/1/2006; ; 700+ words
; This paper studies the effect of variable viscosity on the transient Couette flow of dusty fluid with heat transfer between parallel plates. The fluid is acted upon by a constant pressure gradient and an external uniform magnetic field is applied perpendicular to the plates. The parallel plates are
