A 4-drum delayed coking unit in a petroleum refinery. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes.
Non-electromagnetic waves can also exhibit specular reflection, as in acoustic mirrors which reflect sound, and atomic mirrors, which reflect neutral atoms. For the efficient reflection of atoms from a solid-state mirror, very cold atoms and/or grazing incidence are used in order to provide significant quantum reflection ; ridged mirrors are ...
DCU may refer to: D.C. United , an American professional soccer team based in Washington, D.C., United States DC Universe , the fictional universe that serves as a setting for DC Comics stories
Types of two-mirror optical cavities, with mirrors of various curvatures, showing the radiation pattern inside each cavity. Light confined in a resonator will reflect multiple times from the mirrors, and due to the effects of interference, only certain patterns and frequencies of radiation will be sustained by the resonator, with the others being suppressed by destructive interference.
Justice League: Crisis on Infinite Earths is a 2024 three-part American animated superhero film featuring the DC Comics superhero team the Justice League and based on the DC Comics storyline Crisis on Infinite Earths (1985–1986) written by Marv Wolfman and pencilled by George Pérez.
After the events of Infinite Crisis, DC included a backup feature titled "History of the DCU" in 52, running in issues #2–11 and written by Dan Jurgens. In this version, Donna Troy, now in possession of Harbinger's orb, tells the story of the history of the DCU up to Infinite Crisis.
C (pronounced / ˈ s iː / – like the letter c) [6] is a general-purpose programming language.It was created in the 1970s by Dennis Ritchie and remains very widely used and influential.
The Planck response is the additional thermal radiation objects emit as they get warmer. Whether Planck response is a climate change feedback depends on the context. In climate science the Planck response can be treated as an intrinsic part of warming that is separate from radiative feedbacks and carbon cycle feedbacks.
