The prolific Jean Warin, one of the great engravers, finally established the use of the fly press, a variation on the screw press in which the helix angle of the screw was much increased.
Thickness swelling of the samples also was influenced by increased pressure but variation in press temperature did not result in any influence on dimensional stability.
The rocker press represents another variation.
In the bench press, the decline variation is stronger than the prone or incline.
Four different arm press settings accommodate variations in range of motion and exercise preferences, approximating the specificity of a free-weight workout while providing protection from injury.
Uber's full-court press on service variations that take advantage of its network of drivers offer an interesting look at its business strategy – which presumably involves offering an Uber for everything, everywhere, but figuring out the best way to do that with manageable regional pilots first.
Previous studies on cox1 mitochondrial DNA (Ando et al., 2001) and RAPD analyses (Sithithaworn et al., in press) have detected molecular variation between isolates of O. viverrini from Thailand and Laos, suggesting potential population sub-structuring.
"The park I work in is a sand plain of about 25km across and I think you'd be hard pressed to find any variation across that at all," Cramer says.
This led to strong advocacy for the primacy of the nature of the organism in evolutionary explanations at a time when standard evolutionary biology had reduced the nature of the organism to "random variation" (Brooks in press).
The combination of materials engineering and structure design enables the fiber to scavenge versatile mechanical energy, including stretch, bend, twist and press, through a gap size variation induced electrostatic effect.
