Unaí
Unaí is a municipality in the state of Minas Gerais, Brazil.
History
In the municipality of Unai, there is the archaeological site Cave Gentile II, which records traces of hunter-gatherer peoples of more than 10,000 years, and gardeners people of almost 4000 years, they grew, according abundant plant remains: Corn , peanuts, pumpkin and gourd. In the city, it has the record of the oldest Brazilian ceramics outside the Amazon, dated 3500 years.
At the time of arrival of the first Europeans to Brazil, the central portion of Brazil was occupied by indigenous Macro-Ge linguistic trunk, as acroás, the xacriabás, the Xavante, the Kayapo, the Javaés, among others povos.
Over the centuries XVI, XVII and XVIII, numerous expeditions composed of Portuguese descent (called Scouts) swept the region in search of gold, precious stones and hand indigenous slave labor.
In the nineteenth century, the farmer Domingos Pinto Brochado settled, along with their families, in an area near the Rio Preto called White Grass. In 1873, the village was elevated to the rank of belonging to Paracatu district, with Rio Preto name. In 1923, the district was renamed to Unai, which is a translation for the Tupi language, the ancient name of the district, Rio Preto. In 1943, Unai emancipated the city of Paracatu.
Unit prefix
A unit prefix is a specifier or mnemonic that is prepended to units of measurement to indicate multiples or fractions of the units. Units of various sizes are commonly formed by the use of such prefixes. The prefixes of the metric system, such as kilo and milli, represent multiplication by powers of ten. In information technology it is common to use binary prefixes, which are based on powers of two. Historically, many prefixes have been used or proposed by various sources, but only a narrow set has been recognised by standards organisations.
Metric prefixes
The prefixes of the metric system precede a basic unit of measure to indicate a decadic multiple and fraction of a unit. Each prefix has a unique symbol that is prepended to the unit symbol. Some of the prefixes date back to the introduction of the metric system in the 1790s, but new prefixes have been added, and some have been revised. The International Bureau of Weights and Measures has standardised twenty metric prefixes in resolutions dating from 1960 to 1991 for use with the International System of Units (SI).
Stella (yacht)
The Stella is a 'one-design' Bermuda rig sloop yacht, designed for cruising and racing by the noted yacht designer CR (Kim) Holman in 1959. The design was to the requirements of a customer who had seen the Nordic Folkboat and decided that the English east coast needed a similar vessel but modified for North Sea as opposed to Baltic conditions and a competitive racer on handicap. The prototype: Stella No. 1 La Vie en Rose was built to win the 1959 Burnham (on Crouch) week, which she promptly did. Clinker built of mahogany or larch on oak frames.
The restoration of Amulet, a Stella class yacht originally built in Fort William in 1964, is described by Bob Orrell in the book Amulet: A Charm Restored and Sailed to the Western Isles.
Fleets exist in the UK (estimated 100 built) and Australia (approximately 20 built).
Key dimensions
Stella (software)
Stella, a computer program available in three versions (Great Stella, Small Stella and Stella4D), was created by Robert Webb of Australia. The programs contain a large library of polyhedra which can be manipulated and altered in various ways.
Polyhedra
Polyhedra in Great Stella's library include the Platonic solids, the Archimedean solids, the Kepler-Poinsot solids, the Johnson solids, some Johnson Solid near-misses, numerous compounds including the uniform polyhedra, and other polyhedra too numerous to list here. Operations which can be performed on these polyhedra include stellation, faceting, augmentation, dualization (also called "reciprocation"), creating convex hulls, and others.
All versions of the program enable users to print nets for polyhedra. These nets may then be assembled into actual three-dimensional polyhedral models of great beauty and complexity.
Stella 4D
In 2007, a Stella4D version was added, allowing the generation and display of four-dimensional polytopes (polychora), including a library of all convex uniform polychora, and all currently known nonconvex star polychora, as well as the uniform duals. They can be selected from a library or generated from user created polyhedral vertex figure files.
Stella (given name)
Stella is a feminine given name of Latin and Italian origin, meaning "star".
