Nacional Typefoundry

Fundición Tipográfica Nacional or the Nacional Typefoundry was for many years the leading type foundry of Spain. It was founded in Madrid in 1915 and functioned there until bought out by Fundición Tipográfica Neufville of Barcelona in 1971. It employed prestigious designers like Carlos Winkow and Enric Crous-Vidal and was noted for its bold and striking art deco faces.

Radar (radio)

Radar Radio (also referred to as Radar Music, colloquially called Radar) was an Australian Digital Radio station. It was run by Southern Cross Austereo from its launch date on 11 December 2008 to the closure of the station Monday 25 November 2013. The Radar Radio website was also taken down on the same day as the station closure.

History

Radar started broadcasting online before Digital Radio launched in Australia on 11 December 2008. The station only played unsigned bands and there were no announcers on air.

In 2009, the station commenced broadcasting on Digital Radio as soon as it was rolled out in Sydney, Melbourne, Brisbane, Adelaide and Perth.

In late 2009, the station changed its format from unsigned music to new music. While unsigned bands were still played, they only appeared every fourth song. At the same time, Reegan McLaughlin was employed as an announcer and appeared frequently on air.

In November 2013, the station was replaced with TripleM Classic Rock.

Availability

The station was heard on DAB+ radios in Sydney, Melbourne, Brisbane, Adelaide and Perth.

Catalysis

Catalysis (/kəˈtælᵻsᵻs/) is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst (/ˈkætəlᵻst/). With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.

Technical perspective

In the presence of a catalyst, less free energy is required to reach the transition state, but the total free energy from reactants to products does not change. A catalyst may participate in multiple chemical transformations. The effect of a catalyst may vary due to the presence of other substances known as inhibitors or poisons (which reduce the catalytic activity) or promoters (which increase the activity). The opposite of a catalyst, a substance that reduces the rate of a reaction, is an inhibitor.

Catalyzed reactions have a lower activation energy (rate-limiting free energy of activation) than the corresponding uncatalyzed reaction, resulting in a higher reaction rate at the same temperature and for the same reactant concentrations. However, the detailed mechanics of catalysis is complex. Catalysts may affect the reaction environment favorably, or bind to the reagents to polarize bonds, e.g. acid catalysts for reactions of carbonyl compounds, or form specific intermediates that are not produced naturally, such as osmate esters in osmium tetroxide-catalyzed dihydroxylation of alkenes, or cause dissociation of reagents to reactive forms, such as chemisorbed hydrogen in catalytic hydrogenation.

Public Relations Exercise

Public Relations Exercise were a Leicester, England based post-hardcore/alternative rock group. A five-piece combining aspects of screamo and math rock, layered with penetrative and socially observant lyrics.

History

The band began as a product of the development of bedroom songwriters Martin Smith and Lloyd Carter. From an early age, they worked on various projects with local drummer Danny Star, and with the later addition of Irish-born bassist, Tiernan Welch, and guitarist, Spencer Lee, their line-up was finalised in September 2005. The name is taken from the inlay of Radiohead's second album, The Bends.

In their short history; Public Relations Exercise played with acts including Youthmovies, 65daysofstatic, Foals and many others. After demoing material for some time, the band recorded their debut single 'Subteniente', at Far Heath Studios with producer Angus Wallace (The Fall, The Prodigy) in 2007, which was released as a through Nottingham based Field Records in conjunction an extensive UK tour with ex-Million Dead frontman Frank Turner and London Hardcore outfit Score One For Safety.
