Lambda probes are used to reduce vehicle emissions by ensuring that engines burn their fuel efficiently and cleanly.

In around 1904, the New Jersey inventor J. Walter Christie introduced a sliding pillar suspension system with vertical coil springs, which would appear to be the inspiration for that used by Lancia on its Lambda from around 1922.

The Gnome Lambda seven-cylinder 80 hp rotary engine was also produced by the Oberursel firm as the Oberursel U. 0 Umlaufmotor ( the generic German term for a rotary engine ) as their first-ever powerplant for German military aircraft, and was used on the initial versions of the famous Fokker Eindecker fighter, the Fokker E.

Gnome also tried their hand at a 14-cylinder two-row version, the Double Lambda of 160 hp ( 120 kW ), but this saw little use, even though it was copied by Oberursel as the U. III in Germany, and used in a few early Fokker fighter designs without success.

Photographic paper is exposed to light in a controlled manner, either by placing a negative in contact with the paper directly to produce a contact print, by using an enlarger in order to create a latent image, using digital printers such as the LightJet or Lambda to create a latent image, by exposing in some types of camera to produce a photographic negative, by scanning a modulated light source over the paper, or by placing objects upon it to produce photograms.

Started in 1872 and re-established in 1922 by Lambda Chi Alpha Fraternity, Alpha Gamma Rho Fraternity, and Alpha Phi Sorority ; the MSU Greek system now consists of 55 Greek lettered student societies.
