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).

.onion

.onion is a special-use top level domain suffix designating an anonymous hidden service reachable via the Tor network. Such addresses are not actual DNS names, and the .onion TLD is not in the Internet DNS root, but with the appropriate proxy software installed, Internet programs such as web browsers can access sites with .onion addresses by sending the request through the network of Tor servers. The purpose of using such a system is to make both the information provider and the person accessing the information more difficult to trace, whether by one another, by an intermediate network host, or by an outsider.

Format

Addresses in the .onion TLD are generally opaque, non-mnemonic, 16-character alpha-semi-numeric hashes which are automatically generated based on a public key when a hidden service is configured. These 16-character hashes can be made up of any letter of the alphabet, and decimal digits from 2 to 7, thus representing an 80-bit number in base32. It is possible to set up a human-readable .onion URL (e.g. starting with an organization name) by generating massive numbers of key pairs (a computational process that can be parallelized) until a sufficiently desirable URL is found.

Onion

The onion (Allium cepa L.) (Latin cepa = onion), also known as the bulb onion or common onion, is a vegetable and is the most widely cultivated species of the genus Allium.

This genus also contains several other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion (A. fistulosum), the Egyptian onion (A. ×proliferum), and the Canada onion (A. canadense). The name "wild onion" is applied to a number of Allium species, but A. cepa is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established in some regions. The onion is most frequently a biennial or a perennial plant, but is usually treated as an annual and harvested in its first growing season.

The onion plant has a fan of hollow, bluish-green leaves and the bulb at the base of the plant begins to swell when a certain day-length is reached. In the autumn, the foliage dies down and the outer layers of the bulb become dry and brittle. The crop is harvested and dried and the onions are ready for use or storage. The crop is prone to attack by a number of pests and diseases, particularly the onion fly, the onion eelworm, and various fungi cause rotting. Some varieties of A. cepa, such as shallots and potato onions, produce multiple bulbs.
