The moderator band (also known as septomarginal trabecula [1]) is a band of cardiac muscle found in the right ventricle of the heart. [2] [3] [4] It is well-marked in sheep and some other animals, including humans.
Tricuspid atresia is a form of congenital heart disease whereby there is a complete absence of the tricuspid valve. [2] Therefore, there is an absence of right atrioventricular connection. [2] This leads to a hypoplastic (undersized) or absent right ventricle. This defect occurs during prenatal development, when the heart does not finish ...
A wave turn, commonly found on Rocky Mountain Construction roller coasters, is a 90-degree banked turn that incorporates a small camelback hill. [20] The airtime feature separates wave turns from typical banked turns. [20] When a train banks either right or left into an inclined turn, it traverses an airtime hill while banked at 90 degrees.

A loop can also be performed by rolling inverted and making the same maneuver but diving towards the ground. It can be visualized as making a loop of ribbon, hence the name it is given (there is an animation depicting a loop on the bottom of this page). A roll is simply rotating the plane about its roll axis, using the ailerons. It can be done ...
The X/Y plane coincides with Earth's equatorial plane, with the +X axis pointing toward the vernal equinox and the Y axis completing a right-handed set. The ECI reference frame is not truly inertial because of the slow, 26,000 year precession of Earth's axis , so the reference frames defined by Earth's orientation at a standard astronomical ...
