Three quivers. A quiver is a container for holding arrows or bolts. It can be carried on an archer's body, the bow, or the ground, depending on the type of shooting and the archer's personal preference. Quivers were traditionally made of leather, wood, furs, and other natural materials, but are now often made of metal or plastic.
In theoretical physics, a quiver diagram is a graph representing the matter content of a gauge theory that describes D-branes on orbifolds. Quiver diagrams may also be used to described N = 2 {\displaystyle {\mathcal {N}}=2} supersymmetric gauge theories in four dimensions.
The octane rating of aviation gasoline was extremely important in determining aero engine performance in the aircraft of World War II. [3] The octane rating affected not only the performance of the gasoline, but also its versatility; the higher octane fuel allowed a wider range of lean to rich operating conditions. [3]

The amount of debris in low Earth orbit has increased tremendously, putting satellites and the International Space Station in danger of colliding with even the tiniest bits of space junk.
Yebira, Ebira and Shiko (箙, lit. the "[Japanese] Quiver (of Arrows)") are types of quiver used in Japanese archery. The quiver is unusual in that in some cases, it may have open sides, while the arrows are held in the quiver by the tips which sit on a rest at the base of the ebira, and a rib that composes the upper part and keeps them in place.
