# BTC-T MG ZS EX259

The BTC-T MG ZS EX259 is a BTC-Touring class racing car that was built for the 2001 British Touring Car Championship season by West Surrey Racing, who ran MG's official works program.

## Works career

Partway through the 2001 BTCC season, WSR began entering their BTCC spec MG ZS, returning as a works MG team under the name of MG Sport & Racing. The new car's first appearance was in round 21, held at Silverstone, driven by Anthony Reid and Warren Hughes. Although ineligible to score points, the car showed some initial promise, with a victory at Brands Hatch Indy Circuit, the penultimate round of the season - indeed, it was the only non-Vauxhall entry to win in 2001.
For 2002, WSR entered 4 cars - 2 MG Sport & Racing entries for Reid and Hughes, and a satellite team, racing under the "Team Atomic Kitten" banner, with Gareth Howell and Colin Turkington driving for this team. The car proved to be reasonably competitive in its first full season; WSR finished 2nd in both the Teams and Manufacturers standings, and Reid finished 4th in the Driver's championship. However, they were 151 points behind the Triple 8-entered Astra Coupes in the Manufacturers championship, as that team remained dominant.
For 2003, the team entered 3 cars for Reid, Turkington and Hughes, this time all entered as works drivers. The season proved to be less successful than 2002 - with Honda Racing demoting MG to 3rd in both the Constructors and Teams standings, although MG once again won 3 races, with Reid slipping to 6th in the Drivers championship.

## Independent's career

After 3 seasons, MG withdrew their works support for WSR in 2004. WSR, however, continued to enter a pair of MG ZS, driven by Reid and Turkington, whilst Jason Hughes entered an older ZS in his own Kartworld Racing team. Using their 3 years of knowledge gained from developing the car, the team won the Independents championship, and also a 3rd place in the Team standings. Anthony Reid was once again the best-placed driver, finishing an impressive 4th in the Driver's championship standings, and was crowned as the Independent champion.
With Turkington departing for VX Racing, and Reid being involved in an abortive MG entry for the 2005 DTM season, WSR chose to enter a single car, driven by Rob Collard, whilst Jason Hughes continued to enter his MG ZS, albeit at select events. Despite a low budget, Collard impressed, managing to secure 2 wins, and he finished 7th overall.
For 2006, Turkington returned to the team, partnering the retained Collard. The team made the decision to switch to the facelifted ZS model, the A new sponsorship deal was struck with the RAC, with the team now entering cars under the Team RAC name. A successful season followed, with Turkington finishing runner-up in the Independents, and finishing in a fine 3rd place overall. Team RAC switched to the BMW 320si for 2007, thus ending a 6-year partnership between MG and WSR. Kartworld Racing entered 2 cars, running on bio-ethanol, in 2007 (driven by Hughes and Fiona Leggate), reducing down to 1 for 2008, which would prove to be the cars final season in the BTCC.

# Diablo Lake

Diablo Lake is a reservoir in the North Cascade mountains of northern Washington state, United States. Created by Diablo Dam, the lake is located between Ross Lake and Gorge Lake on the Skagit River at an elevation of 1,201 feet (366 m) above sea level. Diablo Lake is part of the Skagit River Hydroelectric Project and managed by Seattle City Light.

## History

The Skagit Valley was formed via runoff from Cordilleran Glacier. The turquoise hue of the lake's water is attributed to surrounding glaciers grinding rocks into glacial flour that stays suspended in the lake.

### Diablo Dam

The Diablo Dam is a part of the Skagit River Hydroelectric Project, which is owned and operated by Seattle City Light. Construction finished in 1930 and the dam became operational in 1936.

# Cygnus Solutions

Cygnus Solutions, originally Cygnus Support, was founded in 1989 by John Gilmore, Michael Tiemann and David Henkel-Wallace to provide commercial support for free software. Its tagline was: Making free software affordable.
For years, employees of Cygnus Solutions were the maintainers of several key GNU software products, including the GNU Debugger and GNU Binutils (which included the GNU Assembler and Linker). It was also a major contributor to the GCC project and drove the change in the project's management from having a single gatekeeper to having an independent committee. Cygnus developed BFD, and used it to help port GNU to many architectures, in a number of cases working under non-disclosure to produce tools used for initial bringup of software for a new chip design.
Cygnus was also the original developer of Cygwin, a POSIX layer and the GNU toolkit port to the Microsoft Windows operating system family, and of eCos, an embedded real-time operating system.
In the 2001 documentary film Revolution OS, Tiemann indicates that the name "Cygnus" was chosen from among several names that incorporated the acronym "GNU" such as "magnum", "wingnut", and "lugnut". According to Stan Kelly-Bootle, it was recursively defined as Cygnus, your GNU Support.
On November 15, 1999, Cygnus Solutions announced its merger with Red Hat, and it ceased to exist as a separate company in early 2000. As of 2007, a number of Cygnus employees continue to work for Red Hat, including Tiemann, who serves as Red Hat's Vice President of Open Source Affairs, and formerly served as CTO.

# Marcianists

The Marcianists were a sect of Messalians founded by Marcian of Pontus in the sixth century. They were regarded as heretics by Chalcedonian Christians.
Sophronius of Jerusalem, in his Synodical Letter, names their leader as Lampetius, a follower of Marcian. He is described as having a sect of his own, the Lampetianoi, by Timothy of Constantinople and Maximus the Confessor. Timothy, writing probably towards 600, classifies the Messalians, Euchites, Enthusiasts, Choreuts, Adelphians and Eustathians as Marcianist sects. He says that Marcian was a moneychanger during the reigns of Justinian I (527–565) and Justin II (565–574). He does not name any contemporary event in connection with the Marcianists, possibly because the sect was extinct by his time. Timothy's description of Marcianism shows that they rejected charity and believes that misfortune reflected a lack of the Holy Spirit:
   They say neither to give alms to the beggar, nor to the widow, nor to the orphan, nor to those in difficult circumstances, nor to those afflicted with leprosy, nor to those who have encountered thieves, barbarian invasion or any other misfortune. Rather they should keep it all for themselves because those other (unfortunates) are really poor in the spirit.
The name at least still existed as an accusation. In the 590s, John of Chalcedon and Athanasius of Isauria condemned for Marcianism fled from Constantinople to Rome to appeal their cases to Pope Gregory the Great. It is clear from Gregory's letters that the heresy of Marcianism was unknown in Rome. Gregory absolved John of heresy in 595 and Athanasius in 596, although had to first denounce a book in his possession containing Manichaean errors. The emperor Maurice was accused by a Constantinopolitan mob of being a Marcianist in 602, a fact recorded by both Theophylact Simocatta and Theophanes the Confessor. This accusation may have referred to the emperor's refusal to ransom captives from the war with the Avars in 598–599.

# Dialogues II

Dialogues II is a composition for piano and chamber orchestra by the American composer Elliott Carter. It was composed in celebration of the conductor Daniel Barenboim's 70th birthday. The work was first performed at La Scala, Milan on October 25, 2012, by Barenboim on the piano and the Orchestra of La Scala under the conductor Gustavo Dudamel. Composed at the age of 103, Dialogues II was one of Carter's last completed orchestral compositions before his death in November 2012. The piece is a follow-up to the composer's 2003 Dialogues, which was a finalist for the 2005 Pulitzer Prize for Music.

## Composition

Dialogues II is composed in a single movement and has a duration of roughly 5 minutes. In dedicating the piece to Daniel Barenboim, Carter wrote in the score program notes, "The dynamo of enthusiasm that propels his extraordinary musical skills; performing, conducting and imagining new ideas and his views on many varied conceptions make Daniel [Barenboim] a model and an exciting stimulus for us all." He concluded, "I hope a little of that reveals itself in this 70th birthday present."

### Instrumentation

The work is scored for solo piano and a chamber orchestra comprising flute, oboe, clarinet, bassoon, two horns, trumpet, trombone, and strings.

## Reception

Reviewing a performance of the work at Barenboim's 70th birthday concert, Rosie Pentreath of the BBC Music Magazine declared Dialogues II "the only work, one can confidently say, written by a 103-year old." She added, "it is brief, gnomic, and confidently played." The composition was also lauded by Keith Bruce of The Herald.
# Cytochrome P450 BM3

Cytochrome P450 BM3 is a Prokaryote Cytochrome P450 enzyme originally from Bacillus megaterium catalyzes the hydroxylation of several long-chain fatty acids at the ω–1 through ω–3 positions. This bacterial enzyme belongs to CYP family CYP102, with the CYP Symbol CYP102A1.This CYP family constitutes a natural fusion between the CYP domain and an NADPH-dependent cytochrome P450 reductase.
# Cytochrome P450 aromatic O-demethylase

Cytochrome P450 aromatic O-demethylase is a bacterial enzyme that catalyzes the demethylation of lignin and various lignols. The net reaction follows the following stoichiometry, illustrated with a generic methoxy arene:
    ArOCH$_3$ + O$_2$ + 2 e$^−$ + 2 H$^+$ → ArOH + CH$_2$O + H$_2$O
The enzyme is notable for its promiscuity, affecting the O-demethylation of a range of substrates, including lignin.
It is a heterodimeric protein derived from the products of two genes. The component proteins are a cytochrome P450 enzyme (encoded by the gcoA gene from the family CYP255A) and a three-domain reductase (encoded by the gcoB gene) complexed with three cofactors (2Fe-2S, FAD, and NADH).

## Mechanism

GcoA and GcoB form a dimer complex in solution. GcoA process the substrate while GcoB provides the electrons to support the mixed function oxidase. As with other P450's, monooxygenation of the substrate proceeds concomitantly with reduction of half an equivalent of O$_2$ to water. An oxygen rebound mechanism can be assumed. GcoA positions the aromatic ring within the hydrophobic active site cavity where the heme is located.

## Structure

GcoA has a typical P450 structure: a thiolate-ligated heme next to a buried active site. GcoB is however unusual. Cytochrome P450s normally are complemented by either a cytochrome P450 reductase or a ferredoxin and ferredoxin reductase; its electrons are carried by NAD+ or NADP+. GcoB however has a single polypeptide. This polypeptide has an N-terminal ferredoxin with both an NAD(P)+ and also an FAD binding region.
CcoA and GcoB are closely interlinked, acting as an heterodimer in solution. The surface of GcoB has an acidic patch that must interact with the matching basic region in GcoA. It is assumed that the part of GcoB interacting with GcoA is at the intersection between the FAD binding domain and ferredoxin domain. To achieve this GcoB would have to go through some structural change, which would represent a new class of P450 systems (family N).

## Potential applications

Cytochrome P450 aromatic O-demethylase assists in the partial O-demethylation of lignin. The resulting 1,2-diols are well suited for oxidative degradation via intra- and extra-diol dioxygenases. Thus O-demethylated lignins are potentially susceptible to partial depolymerization. With fewer crosslinks, the modified ligand is potentially more useful than the precursor., ranging from fuels
