The image shows four circular diagrams labeled as Figures 8, 9, 10, and 11. Each diagram is a circle with a complex pattern of lines and curves drawn within it. The lines radiate from the center of the circle and are arranged in a symmetrical pattern. There are also curved lines that form petal-like shapes within the circle. Each figure is labeled with a number and the text 'Fig.' below it. Above each figure is the text 'ΩH A1'. The background is a pale yellow color, and the diagrams are drawn in black lines.
