Period (per) is a gene located on the X chromosome of Drosophila melanogaster. Oscillations in levels of both per transcript and its corresponding protein PER have a period of approximately 24 hours and together play a central role in the molecular mechanism of the Drosophila biological clock driving circadian rhythms in eclosion and locomotor activity. Mutations in the per gene can shorten (perS), lengthen (perL), and even abolish (per0) the period of the circadian rhythm.
The period gene and three mutants (perS, perL, and per0) were isolated in an EMS mutagenesis screen by Ronald Konopka and Seymour Benzer in 1971. The perS, perL, and per0 mutations were found to complement each other, so it was concluded that the three phenotypes were due to mutations in the same gene. The discovery of mutants that altered the period of circadian rhythms in eclosion and locomotor activity (perS and perL) indicated the role of the per gene in the clock itself and not an output pathway. The period gene was first sequenced in 1984 by Michael Rosbash and colleagues. In 1998, it was discovered that per produces two transcripts (differing only by the alternative splicing of a single untranslated intron) which both encode the PER protein.
PeR that stands for "Please explain the Rhythm" is a Latvian pop and beatboxing band formed in 2007. The original line-up was Ralfs Eilands, Emīls Vegners, and Pēteris Upenieks. Vegners left the band in 2007 and was replaced by Edmunds Rasmanis. But when Upelnieks left the trio in 2011, he was not replaced, rendering the band a duo consisting of just Eilands and Rasmanis. After three failed attempts in earlier years to represent Latvia in the Eurovision Song Contest, PeR won the 2013 Dziesma contest and represented the country in the 2013 Contest with the song "Here We Go".
The band was founded in 2007, with original members; Ralfs Eilands, Emīls Vegners, and Pēteris Upenieks. On 21 July 2007, the band first appeared and performed on Dziesma manai paaudzei, the Latvian music festival. After the festival, the band travelled to Moscow, Russia, to compete with other artists on the talent show Minuta Slavy (Minute of Fame), with the band coming in fourth place during voting. The band returned to Latvia where they received an invitation to participate in the annual music event Bildes 2007. This was the last event with the original members.
The domain name "name" is a generic top-level domain (gTLD) in the Domain Name System of the Internet. It is intended for use by individuals for representation of their personal name, nicknames, screen names, pseudonyms, or other types of identification labels.
The top-level domain was founded by Hakon Haugnes and Geir Rasmussen and initially delegated to Global Name Registry in 2001, and become fully operational in January 2002. Verisign was the outsourced operator for .name since the .name launch in 2002 and acquired Global Name Registry in 2008.
On the .name TLD, domains may be registered on the second level (john.name
) and the third level (john.doe.name
). It is also possible to register an e-mail address of the form [email protected]
. Such an e-mail address may have to be a forwarding account and require another e-mail address as the recipient address, or may be treated as a conventional email address (such as [email protected]
), depending on the registrar.
When a domain is registered on the third level (john.doe.name
), the second level (doe.name
in this case) is shared, and may not be registered by any individual. Other second level domains like johndoe.name
remain unaffected.
A name is a term used for identification. Names can identify a class or category of things, or a single thing, either uniquely, or within a given context. A personal name identifies, not necessarily uniquely, a specific individual human. The name of a specific entity is sometimes called a proper name (although that term has a philosophical meaning also) and is, when consisting of only one word, a proper noun. Other nouns are sometimes called "common names" or (obsolete) "general names". A name can be given to a person, place, or thing; for example, parents can give their child a name or scientist can give an element a name.
Caution must be exercised when translating, for there are ways that one language may prefer one type of name over another. A feudal naming habit is used sometimes in other languages: the French sometimes refer to Aristotle as "le Stagirite" from one spelling of his place of birth, and English speakers often refer to Shakespeare as "The Bard", recognizing him as a paragon writer of the language. Also, claims to preference or authority can be refuted: the British did not refer to Louis-Napoleon as Napoleon III during his rule.
In computing, naming schemes are often used for objects connected into computer networks.
Server naming is a common tradition. It makes it more convient to refer to a machine by name than by its IP address.
CIA named their servers after states.
Server names may be named by their role or follow a common theme such as colors, countries, cities, planets, chemical element, scientists, etc. If servers are in multiple different geographical locations they may be named by closest airport code.
Such as web-01, web-02, web-03, mail-01, db-01, db-02.
Airport code example:
City-State-Nation example:
Thus, a production server in Minneapolis, Minnesota would be nnn.ps.min.mn.us.example.com, or a development server in Vancouver, BC, would be nnn.ds.van.bc.ca.example.com.
Large networks often use a systematic naming scheme, such as using a location (e.g. a department) plus a purpose to generate a name for a computer.
For example, a web server in NY may be called "nyc-www-04.xyz.net".
