  2. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    ASME Y14.44-2008 continues the convention of Plug P and Jack J when assigning references for electrical connectors in assemblies where a J (or jack) is the more fixed and P (or plug) is the less fixed of a connector pair, without regard to the gender of the connector contacts.

  3. p–n junction - Wikipedia

    en.wikipedia.org/wiki/P–n_junction

    A p–n junction diode. The circuit symbol is also shown. A p–n junction is a combination of two types of semiconductor materials, p-type and n-type, in a single crystal. The "n" (negative) side contains freely-moving electrons, while the "p" (positive) side contains freely-moving electron holes.

  4. Peanut butter and jelly sandwich - Wikipedia

    en.wikipedia.org/wiki/Peanut_butter_and_jelly...

    There are many variations of the PB&J, which itself is a hybrid between a peanut butter sandwich and a jam sandwich. In American terminology, jelly is a fruit-based spread, made primarily from fruit juice boiled with a gelling agent and allowed to set, while jam contains crushed fruit and fruit pulp, heated with water and sugar and cooled until ...

  5. Jahwist - Wikipedia

    en.wikipedia.org/wiki/Jahwist

    The latest additions of the P text frame the J narratives. P text "glue" can be perceived in Genesis 1 (framing the book), Genesis 5 recounts Genesis 1 and provides a characteristic priestly lineage detail for Adam and, amongst other locations, Genesis 35, bridging the J text patriarchal narratives to the "E" Joseph narrative with more lineage ...

  6. International Phonetic Alphabet - Wikipedia

    en.wikipedia.org/wiki/International_Phonetic...

    However, in precise notation there is a difference between a fricative release in [tᶴ] and the affricate [t͜ʃ], between a velar onset in [ᵏp] and doubly articulated [k͜p]. [100] Superscript letters can be meaningfully modified by combining diacritics, just as baseline letters can.

  7. Letter case - Wikipedia

    en.wikipedia.org/wiki/Letter_case

    In other words, while the shapes of letters like A, B, E, H, K, M, O, P, T, X, Y and so on are shared between the Latin, Greek, and Cyrillic alphabets (and small differences in their canonical forms may be considered to be of a merely typographical nature), it would still be problematic for a multilingual character set or a font to provide only ...

  8. Total angular momentum quantum number - Wikipedia

    en.wikipedia.org/wiki/Total_angular_momentum...

    The relation between the total angular momentum vector j and the total angular momentum quantum number j is given by the usual relation (see angular momentum quantum number) ‖ ‖ = (+) The vector's z -projection is given by j z = m j ℏ {\displaystyle j_{z}=m_{j}\,\hbar } where m j is the secondary total angular momentum quantum number ...

  9. Affricate - Wikipedia

    en.wikipedia.org/wiki/Affricate

    The exact phonetic difference varies between languages. In stop–fricative sequences, the stop has a release burst before the fricative starts; but in affricates, the fricative element is the release. Phonologically, stop–fricative sequences may have a syllable boundary between the two segments, but not necessarily.
