In mathematics, and more specifically in abstract algebra, a *-algebra (or involutive algebra) is a mathematical structure consisting of two involutive rings R and A, where R is commutative and A has the structure of an associative algebra over R. Involutive algebras generalize the idea of a number system equipped with conjugation, for example the complex numbers and complex conjugation, matrices over the complex numbers and conjugate transpose, and linear operators over a Hilbert space and Hermitian adjoints.
In mathematics, a *-ring is a ring with a map * : A → A that is an antiautomorphism and an involution.
More precisely, * is required to satisfy the following properties:
for all x, y in A.
This is also called an involutive ring, involutory ring, and ring with involution. Note that the third axiom is actually redundant, because the second and fourth axioms imply 1* is also a multiplicative identity, and identities are unique.
A ringtone or ring tone is the sound made by a telephone to indicate an incoming call or text message. Not literally a tone nor an actual (bell-like) ring any more, the term is most often used today to refer to customizable sounds used on mobile phones.
A phone “rings” when its network indicates an incoming call and the phone thus alerts the recipient. For landline telephones, the call signal can be an electric current generated by the switch or exchange to which the telephone is connected, which originally drove an electric bell. For mobile phones, the network sends the phone a message indicating an incoming call. The sound the caller hears is called the ringback tone, which is not necessarily directly related.
The electromagnetic bell system is still in widespread use. The ringing signal sent to a customer's telephone is 90 volts AC at a frequency of 20 hertz in North America. In Europe it is around 60-90 volts AC at a frequency of 25 hertz. Some non-Bell Company system party lines in the US used multiple frequencies (20/30/40 Hz, 22/33/44 Hz, etc.) to allow "selective" ringing.
Norwegian National Road 150, also known as Ring 3 and formerly Store Ringvei is a beltway limited-access road which circumnavigates Oslo, Norway. It runs from Ryen, through the Sinsen Interchange to Lysaker in Bærum.
The Sinsen Interchange, where Ring 3 meets Trondheimsveien was opened in 1962. The increase in traffic was greater than the capacity of the junction, and thus a bridge was constructed that redirected Trondheimsveien above the roundabout.
Further restructuring was done in 1992, when the Sinsen Line of the Oslo Tramway was redirected outside of the interchange, and in 1994, when National Road 150 was directed below the roundabout. The Norwegian Public Roads Administration plans to connect the Løren Tunnel, a tunnel over National Road 150, with the Sinsen Interchange in summer 2013.
The highway is subdivided into parts with separate names (from Ryen to Lysaker):
Panic! (known as SWITCH (スイッチ, Suitchi) in Japan) is a puzzle point and click video game developed by Sega and Office I and published by Sega in Japan and Data East USA in North America for the Sega CD, in collaboration with the Theatrical Group WAHAHA Hompo. It was released on April 23, 1993 in Japan, localized to North America in 1994, and later released for the PlayStation 2 in Japan on August 8, 2002. The game involves pressing numerous buttons in order to transverse a young boy, called Slap, or his dog, called Stick, through a complex labyrinth. It is one of the few Sega CD games that supports the Sega Mega Mouse.
During the intro, the game explains that a virus has infected the world's computer systems. Slap and his dog Stick (who has been sucked into his TV) must carry an antidote to the central computer to fix it. To this end, Slap and Stick must traverse a grid of levels, pushing buttons to advance.
Each level is presented as a new area with a mechanical device, and a set of buttons to press. Each button causes an animation and/or teleports Slap to another room. Sometimes the buttons are booby-trapped and cause the destruction of a variety of monuments. The grid also features a few game overs on the grid, marked by flashing skulls on the map. The buttons themselves have no indication on what they do when pressed. It is possible to backtrack into previous levels, and buttons once pressed are not marked, unless they were booby-trapped.
Better Call Saul is an American television drama series created by Vince Gilligan and Peter Gould, a spin-off of Breaking Bad. Its first season, which premiered on AMC on February 8, 2015, consists of 10 episodes. The series has been renewed for a second season, which will premiere on February 15, 2016.As of April 6, 2015, 10 episodes of Better Call Saul have aired, concluding the first season.
A command-line interface or command language interpreter (CLI), also known as command-line user interface, console user interface, and character user interface (CUI), is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines).
The CLI was the primary means of interaction with most computer systems until the introduction of the video display terminal in the mid-1960s, and continued to be used throughout the 1970s and 1980s on OpenVMS, Unix systems and personal computer systems including MS-DOS, CP/M and Apple DOS. The interface is usually implemented with a command line shell, which is a program that accepts commands as text input and converts commands to appropriate operating system functions.
Command-line interfaces to computer operating systems are less widely used by casual computer users, who favor graphical user interfaces.
Alternatives to the command line include, but are not limited to text user interface menus (see IBM AIX SMIT for example), keyboard shortcuts, and various other desktop metaphors centered on the pointer (usually controlled with a mouse). Examples of this include the Windows versions 1, 2, 3, 3.1, and 3.11 (an OS shell that runs in DOS), DosShell, and Mouse Systems PowerPanel.
First is the first solo album by David Gates of Bread. The musicians include: Jimmy Getzoff, Jim Gordon, Jim Horn, John Guerin, Larry Carlton, Larry Knechtel, Louie Shelton, Mike Botts and Russ Kunkel. Suite, Clouds & Rain is definitely worth a listen as Gates experimented with his sound.

sixteen silver threats can never ever
be replaced by nice (mahogny desks)
and eventually i wouldn't be able to notice the
difference
(between a cup of coffee and a coffin)
loose your hearing
loose it for fucking good
as some might say
