Selected Borrowings: The American Impact upon the Prairie Co-operative Movement, 1920–39
Prairie protest has been a prominent part of Canadian life since Confedera- tion. Over the years it has gone through several stages,1 but beneath the changes has rested a remarkably consistent set of grievances. Indeed, listing the complaints has become something of a refrain for politicians, editorial writers, novelists and academics. High freight rates, excessive bank charges, railway discrimination, indifference in Ottawa, unfavorable tariffs, manipula- tion of natural resources—the list is well known to all students of Prairie regionalism. So too are the movements sparked by some or all of these grievances — the rebellions of 1870 and 1885, the agitation for provincial status, the radical labor movements, the agrarian unrest, the Progressive party, and the new parties of the 1930's.
Shape and surface texture of molten droplets deposited on cold surfaces
When a molten droplet impacts on a cold surface, the interaction between solidification and fluid dynamics can lead to different shapes and surface textures of deposited droplets. This article presents an experimental study on deposition of small droplets (39 μm diameter) of molten wax ink on solid surfaces. Our results show that both the final shape and the surface texture of deposited droplets are extremely sensitive to deposition conditions, which include initial temperature of droplets, type of substrate surface and distance between substrate and printhead. Different surface textures are observed and shown to depend on the thermal and flow histories of ink droplets during the process of impact. A test using crystalline wax reveals crystallization as one of the major factors in determining the final texture.
