Lotus (Santana album)

Lotus is a 1974 live album recording of the San Franciscan latino rock band Santana at the Osaka Koseinenkin Hall, Osaka, Japan on 3-4 July 1973. It was originally released in 1974 as a triple vinyl LP in Japan only. The first U.S. release was in 1991 as a 2-CD set.

Lotus has been re-issued on vinyl in the Netherlands and on CD in Japan in 2006 as a 3-CD set. It was also re-issued as a 3-LP set in the U.S. in 2013.

Quadrophonic recording

The original live recordings were mixed in 4-channel quadraphonic sound and released in the CBS SQ matrix system. The SQ encoding permits all 4 channels to be contained in a 2 channel stereo version, which is compatible with conventional stereo playback equipment.

Some releases of this album have been marked as "Quad" or "SQ" and some are not. However, all known releases of this album use the same SQ encoded 2 channel recordings. Therefore the 4 independent channels can still be heard on modern equipment provided that the listener has a proper SQ decoder and 4 channel playback system.

Lotus Cortina

Lotus Cortina is the commonly used term for the Ford Cortina Lotus, a high-performance sports saloon, which was produced in the United Kingdom from 1963 to 1970 by Ford in collaboration with Lotus Cars. The original version, which was based on the Ford Cortina Mark 1, was promoted by Ford as the "Consul Cortina developed by Lotus", with "Consul" later being dropped from the name. The Mark 2 was based on the Ford Cortina Mark 2 and was marketed by Ford as the "Cortina Lotus".

There were 3,306 Mark I and 4,093 Mark 2 Lotus Cortinas produced.

Mk1

The history of the Cortina Lotus began in 1961. Colin Chapman had been wishing to build his own engines for Lotus, mainly because the Coventry Climax unit was so expensive. Colin Chapman's chance came when he commissioned Harry Mundy (a close friend and designer of the Coventry Climax engine and technical editor for Autocar) to design a twin-cam version of the Ford Kent engine. Most of the development of the engine was done on the 997cc and 1,340cc bottom end, but in 1962 Ford released the 116E five bearing 1,499 cc engine and work centred on this. Keith Duckworth, from Cosworth, played an important part in tuning of the engine. The engine's first appearance was in 1962 at the Nürburgring in a Lotus 23 driven by Jim Clark. Almost as soon as the engine appeared in production cars (Lotus Elan), it was replaced with a larger capacity unit (82.55 mm bore to give 1,557 cc). This was in order to get the car closer to the 1.6 litre capacity class in motorsport.

Lotus 63

The Lotus 63 was an experimental Formula One car, designed by Colin Chapman and Maurice Philippe for the 1969 season. Chapman's reasoning behind the car was that the 3 litre engines introduced in 1966 would be better served by building a car that could take full advantage of its power while retaining the Lotus 49's simplicity.

Like the Lotus 56 for the Indy 500 (and later F1), the 63 chassis was designed around a four wheel drive system. This was not totally revolutionary at the time, as four wheel drive had been used on the Ferguson P99 F1 car that won at Oulton Park as early as 1961, but with little development thereafter. However, it was not a successful design. In fact, the Matra MS84 was the only 4WD F1 which scored points (driven by Johnny Servoz-Gavin, at the 1969 Canadian Grand Prix) something neither Lotus nor McLaren managed, while Cosworth did not even race their 4WD design. The 63 was an evolution of the 49, but featured wedge shaped rear bodywork and integrated wings, which would be used to great effect in the Lotus 72.

Age (model theory)

In model theory, the age of a structure (or model) A is the class of all finitely generated structures which are embeddable in A (i.e. isomorphic to substructures of A). This concept is central in the construction of a Fraïssé limit.

The main point of Fraïssé's construction is to show how one can approximate a structure by its finitely generated substructures. Thus for example the age of any dense linear order without endpoints (DLO), is precisely the set of all finite linear orderings, which are distinguished up to isomorphism only by their size. Thus the age of any DLO is countable. This shows in a way that a DLO is a kind of limit of finite linear orderings.

One can easily see that any class K which is an age of some structure satisfies the following two conditions:

Fraïssé proved the converse result: when K is any non-empty countable set of finitely generated σ-structures (with σ a signature) which has the above two properties, then it is an age of a countable structure.

Age (journal)

Age is a scientific journal focused on the biology of aging and research on biomedical applications that impact aging. This includes evolutionary biology, biophysics, genetics, genomics, proteomics, molecular biology, cell biology, biochemistry, endocrinology, immunology, physiology, pharmacology, neuroscience, and psychology. It is an international peer-reviewed monthly and the official journal of the American Aging Society. It is published by Springer Science+Business Media, and the editor-in-Chief is Donald K. Ingram. According to the 2012 Journal Citation Reports, its impact factor is 4.084.

Toyota A engine

The A Series engines are a family of inline-four internal combustion engines with displacement from 1.3 L to 1.8 L produced by Toyota Motor Corporation. The series has cast iron engine blocks and aluminum cylinder heads.

The development of the series began in the late 1970s, when Toyota wanted to develop a completely new engine for the Toyota Tercel, successor of Toyota's K engine. The goal was to achieve good fuel efficiency and performance as well as low emissions with a modern design. The A-series includes the first mass-production DOHC, four-valve-per-cylinder engine, the 4A-GE, and a later version of the same motor was one of the first production five-valve-per-cylinder engines.

Toyota joint venture partner Tianjin FAW Xiali still produces the 1.3 L 8A and recently resumed production of the 5A.

1A

The 1.5 L 1A was produced between 1978 and 1980. All variants were belt-driven 8-valve counter-flow SOHC engine with a single, twin-barrel downdraft carburetor.
