Since 2016, it is the home base of the 53rd Fighter Squadron, the first Romanian Air Force squadron equipped with F-16s. [6] The MiG-21 LanceR was officially retired on 15 May 2023. Ceremonies were held at the 71st Air Base and at the 86th Air Base. The MiGs were then flown to the 95th Air Base in Bacău for storage. [7]
A ray trace through a prism with apex angle α. Regions 0, 1, and 2 have indices of refraction, , and , and primed angles ′ indicate the ray's angle after refraction.. Ray angle deviation and dispersion through a prism can be determined by tracing a sample ray through the element and using Snell's law at each interface.
In chemistry, there are three definitions in common use of the word "base": Arrhenius bases, Brønsted bases, and Lewis bases. All definitions agree that bases are substances that react with acids , as originally proposed by G.-F. Rouelle in the mid-18th century.
In a triangle, any arbitrary side can be considered the base. The two endpoints of the base are called base vertices and the corresponding angles are called base angles. The third vertex opposite the base is called the apex. The extended base of a triangle (a particular case of an extended side) is the line that contains the base.
Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically. It was first introduced by Hermann von Helmholtz in late 19th-century Germany as supportive evidence for his perceptual learning theory (Helmholtz, 1909/1962). [1]

Any of the three pairs of parallel faces can be viewed as the base planes of the prism. A parallelepiped has three sets of four parallel edges; the edges within each set are of equal length. Parallelepipeds result from linear transformations of a cube (for the non-degenerate cases: the bijective linear transformations).
A pressure prism is a way of visually describing the variation of hydrostatic pressure within a volume of fluid. When variables of fluid density , depth, gravity , and other forces such as atmospheric pressure are charted, the resulting figure somewhat resembles a prism .
