Their hymenal opening tends to be annular (circumferential). With circumferential or axial flow cooling, the temperature difference remains tolerable. Circumferential and longitudinal muscles edging each segment let the worm move. The maximum compression varies linearly with circumferential rotor speed. Auxiliary Interstate Highways are circumferential, radial, or spur highways that principally serve urban areas. The circumferential and radial roads are systems of interconnected roads, bridges and highways. This City has three Circumferential Roads and four Radial Roads. These include most of the area within the region's outer circumferential highway, I-495. Actin filaments line the spermatheca in a circumferential manner. The windings are such that there is no circumferential current. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. The Urban Ring Project was a planned circumferential surface BRT line. An escharotomy is a surgical procedure used to treat full-thickness (third-degree) circumferential burns. Counterforce orthosis has a circumferential structure surrounding the arm. It could be considered a flash suppressor without circumferential openings.
