Concurrency (road)

A concurrency in a road network is an instance of one physical road bearing two or more different highway, motorway, or other route numbers. When two freeways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap,coincidence,duplex (two concurrent routes), triplex (three concurrent routes) multiplex (any number of concurrent routes),dual routing or triple routing.

Concurrent numbering can become very common in countries that allow it. Where multiple routes must pass through a single mountain crossing, or through a major city, it is often economically and practically advantageous for them all to be accommodated on a single physical road. In some countries, however, concurrent numbering is avoided by posting only one route number on road signs; these routes disappear at the start of the concurrency and reappear when it ends. Criticism of concurrencies include environmental intrusion, as well as being considered a factor in road accidents.

Multiplex (titles)

Multiplex, often abbreviated as mult., is a postpositive adjective that may be placed after one's doctoral or professorial title to signify that the person holds several such titles.

List of minor DC Comics characters

Throughout its history, DC Comics has introduced many characters, including numerous minor characters. These characters range from supporting characters, heroes and villains that appear infrequently, to characters that only take part in a single story.

A

Airstryke

Airstryke is a villain in the DC Universe.

Within the context of the stories, William Kavanagh was given the ability to transform into a pterodactyl/man hybrid by a weapons company Meta/Tech and took the name Airstryke. Count Viper took advantage of these new abilities and used Airstryke to distract Hawkman while Viper tried to take command of the Justice League and thus the world. Airstryke and Viper were soon defeated and Airstryke was sent to Belle Reve Prison. He remained here until he was freed by Neron and was given the chance to sell his soul along with numerous other villains. Airstryke chose not to sell his soul and continued his life of crime. Eventually, Airstryke was returned to prison where he became a victim of Joker's Joker gas. Again, he was defeated and returned to prison. This time he was sent to the Slab. During his stay, Brother Blood attempted to break all the villains out of the prison so they could assist him on his mission. Airstryke was the first to question Blood on his plan. Brother Blood then shot and killed Airstryke for his hubris.

Multiplex (television)

A multiplex or mux (called virtual sub-channel in the United States and Canada, and bouquet in France) is the erroneous term given to the grouping of program services that are sub-grouped as interleaved data packets for broadcast over a network or modulated multiplexed medium, which are split out at the receiving end. There are two different types of groupings, which are closely related but not identical.

In the United Kingdom, a terrestrial multiplex (usually abbreviated mux) has a fixed bandwidth of 8 MHz CODFM of interleaved H.222 packets containing a number of channels. In the United States, a similar arrangement using 6 MHz 8VSB is often described as a channel with virtual sub-channels.

Pay television multiplexes

Many pay television services on cable and satellite television offer program service packages, in which a single provider offers a number of separate channels to its subscribers. The channels may be distinct in regards to the programming format (for example, one channel offering comedy programming and another carrying action and adventure films), be timeshifted, or offer different views of the same event ( such as overviews of a car race, the view from different drivers' cars or a view of the pits). Some pay television program services offer picture in picture (PIP) capabilities to follow the various feeds simultaneously on one screen. If the hardware allows, several channels in one multiplex can be viewed simultaneously. Pay television multiplexes may be purchased on a subscription or a pay-per-view basis.

2+2 road

A 2+2 road is a specific type of dual-carriageway being built in Ireland and in Sweden and in Finland, consisting of two lanes in each direction separated by a steel cable barrier.

These roads do not have hard shoulders and therefore they cannot be designated as Motorway at some future date. The Irish variant,however, has 3.5m lanes where there are a number of Swedish variants some with 3.25m wide lanes.

Junctions are generally at-grade roundabouts and minor roads cross under or over the mainline without connecting. They are also known as "Type 2 dual-carriageways" by the Irish National Roads Authority. These roads look similar to expressways, except that expressways often have interchanges, large medians or concrete barriers between traffic. The United States has 80,000 km of roads that fit this description.

First 2+2

The first road of this type opened in December 2007 as a new greenfield section of the N4 national primary route which joins Dublin to Sligo.
