The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.g. R17A, R17B. The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic ...
An alphanumeric grid (also known as atlas grid [1]) is a simple coordinate system on a grid in which each cell is identified by a combination of a letter and a number. [2]An advantage over numeric coordinates such as easting and northing, which use two numbers instead of a number and a letter to refer to a grid cell, is that there can be no confusion over which coordinate refers to which ...
The letters and numbers in the code indicate the number of cells, cell chemistry, shape, dimensions, the number of parallel paths in the assembled battery and any modifying letters deemed necessary. A multi-section battery (two or more voltages from the same package) will have a multi-section designation.
The complete nomenclature consists of an Approved Item Name (AIN), an extended modifier (if applicable), and the type designation. The AIN is presented in all capital letters, is not abbreviated, and is followed by a colon. Each AIN has a corresponding 6-digit Item Name Code (INC) which can be referenced in the H6 Cataloging Handbook.
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
When writing sequences in shorthand notation, the letter N is often used to represent a nucleotide containing a generic or unidentified nucleobase. nucleoid. Also prokaryon. An irregularly shaped region within a prokaryotic cell which contains most or all of the cell's genetic material, but is not enclosed by a nuclear membrane as in eukaryotes ...
The quote marks must be the standard, straight, double quotation marks ("); curly or other quotes will be parsed as part of the reference name. You may optionally provide reference names even when the reference name is not required. This makes later re-use of the sourced reference easier.
HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the ...
