In computer science, Backus–Naur form is a notation used to describe the syntax of programming languages or other formal languages. It was developed by John Backus and Peter Naur. BNF can be described as a metasyntax notation for context-free grammars. Backus–Naur form is applied wherever exact descriptions of languages are needed, such as in official language specifications, in manuals, and in textbooks on programming language theory. BNF can be used to describe document formats, instruction sets, and communication protocols.
The British National Formulary (BNF) is a United Kingdom (UK) pharmaceutical reference book that contains a wide spectrum of information and advice on prescribing and pharmacology, along with specific facts and details about many medicines available on the UK National Health Service (NHS). Information within the BNF includes indication(s), contraindications, side effects, doses, legal classification, names and prices of available proprietary and generic formulations, and any other notable points. Though it is a national formulary, it nevertheless also includes entries for some medicines which are not available under the NHS, and must be prescribed and/or purchased privately. A symbol clearly denotes such drugs in their entry.

Neferkara I is the cartouche name of a king (pharaoh) who is said to have ruled during the 2nd Dynasty of Ancient Egypt. The exact length of his reign is unknown since the Turin canon lacks the years of rulership and the ancient Egyptian priest Manetho suggests that Neferkara's reign lasted 25 years. Egyptologists evaluate his statement as misinterpretation or exaggeration.

The Seventh Dynasty of Egypt would mark the beginning of the First Intermediate Period in the early 22nd century BC but its actual existence is debated. The only historical account on the Seventh Dynasty was in Manetho's Aegyptiaca, a history of Egypt written in the 3rd century BC, where the Seventh Dynasty appears essentially as a metaphor for chaos. Since next to nothing is known of this dynasty beyond Manetho's account, Egyptologists such as Jürgen von Beckerath and Toby Wilkinson have usually considered it to be fictitious. In a 2015 re-appraisal of the fall of the Old Kingdom, the Egyptologist Hracht Papazian has proposed that the Seventh Dynasty was real and that it consisted of kings usually attributed to the Eighth Dynasty.

Wadjenes, also known as Wadjlas, Ougotlas and Tlas, was an early Egyptian king who may have ruled during the 2nd Dynasty. Since the name form "Wadjenes" is not contemporarily attested as the name of a king, but frequently appears in Ramesside kinglists, Egyptologists to this day are trying to connect Wadjenes with contemporary Horus-kings.
Hudjefa is the pseudonym for a 2nd Dynasty pharaoh as reported on the Turin canon, a list of kings written during the reign of Ramses II. Hudjefa is now understood to mean that the name of the king was already missing from the document from which the Turin canon was copied. The length of the reign associated to Hudjefa on the canon is 11 years. Because of the position of Hudjefa on the Turin list, he is sometimes identified with a king Sesochris reported in the Aegyptiaca, a history of Egypt written by the Egyptian priest Manetho in the 3rd century BC. Manetho credits this pharaoh with 48 years of reign. Egyptologists have attempted to relate Hudjefa with archaeologically attested kings of the period, in particular Seth-Peribsen.
