They were measured, weighed, and prepared for histological analysis of the concentric lines structure.
Figures 4 (for prehatching larvae), 5, and 6 for adult octopi show that the widths of the concentric lines are homogeneous, independent of the age of the organisms.
The Gray Scramble X (double) is in the style of Stella's earlier works, which also contain concentric lines
, some in gray tones and some in color.
Each image in the series (also titled "Afro Margin") presents vertical rows of repeating elements that, from a few paces off, present abstract black circles and oblongs; these alternate with passages of curving concentric lines
that flow sideways while also stacking up and down.
Then, add concentric lines
around each original shape, in turn, taking care to "mirror" the original shape.
Portions of the concentric lines
are located adjacent to the sides and portions and form a barrier that is resistant to the egress of fluid out of the pad's periphery.
The two- and three-stylus models draw concentric lines
on one chart for two or three machines (of two or three functions on one machine), to record actual machine running time versus productive and down time.
A ring-road connected the fast north-south and east-west bus routes, Four concentric lines
were added with stations at intersections with the earlier lines.
On the cover was an intriguing painting of black circles with concentric lines of color around them.
But why all the concentric lines around the shapes?
Balanced on thin legs, the octagonal block of foamcore is covered on one side by shapes reminiscent of auto parts and concentric lines
underscoring the title's association with the controlled chaos of a NASCAR track.
