When was the Amazonian period?

The Amazonian is a geologic system and time period on the planet Mars characterized by low rates of meteorite and asteroid impacts and by cold, hyperarid conditions broadly similar to those on Mars today. The transition from the preceding Hesperian period is somewhat poorly defined. The Amazonian is thought to have begun around 3 billion years ago, although error bars on this date are extremely large (~500 million years). The period is sometimes subdivided into the Early, Middle, and Late Amazonian. The Amazonian continues to the present day.

The Amazonian manatee is a seasonal breeder with a gestational period of 12–14 months and a prolonged calving period. Most births take place between December and July, with about 63% between February and May, during a time of rising river levels in their native region. After the calf is born, it will begin to eat while staying with its mother for 12 – 18 months.

The entire contemporary era on Mars has been named the Amazonian Epoch because researchers originally (and incorrectly) thought Amazonis Planitia to be representative of all Martian plains. Instead, over the past two decades, researchers have realized that the area's youth and extremely smooth surface actually distinguish the area from its neighbors. It is even possible that the area possessed distinctive characteristics when all of Mars was under water.

The peak of the rubber boom between 1880 and 1910 attracted so many merchants and other workers that it was the height of Jewish immigration to the Amazonian Basin; they established new communities along the interior of the Amazon River, in Santarém and Manaus, Brazil, and ventured as far as Iquitos, Peru, on the east side of the Andes. This was a major center on the Amazon for rubber export and related businesses. It was the headquarters of the Peruvian-owned Peruvian Amazon Company (PAC). The rubber boom also attracted Jewish adventurers from England, Alsace-Lorraine and France, and other Europeans, who helped found new Jewish and European institutions in Iquitos, including an opera house.

This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is N6,N6,N6-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating). Other names in common use include trimethyllysine alpha-ketoglutarate dioxygenase, TML-alpha-ketoglutarate dioxygenase, TML hydroxylase, 6-N,6-N,6-N-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase, and (3-hydroxylating). This enzyme participates in lysine degradation and L-carnitine biosynthesis and requires the presence of iron and ascorbate.

Ȼ was not added to Unicode until version 4.1 in 2005, and previously did not exist in character sets. Consequently, few fonts can display it. The cent sign is often substituted for it instead.

Ŭ represents a semivowel in the orthography of Esperanto, which is an international auxiliary language publicly presented in 1887. As in Belarusian, Esperanto Ŭ is pronounced as a non-syllabic , primarily in the diphthongs "aŭ", "eŭ" and rarely "oŭ".

Ƨ was used in the Zhuang alphabet from 1957 to 1986 to indicate the second, or falling, tone (), due to its resemblance to the numeral 2, along with four other letters resembling numbers. (See table). In 1986, Ƨ was replaced by the similarly shaped, but fully Latin, Z, when the alphabet was simplified for use in computers.

The Aceramic Neolithic period began roughly around 8500 BC and can be identified with over a half a dozen sites. The period was most prominent in Western Asia in an economy based on the cultivation of crops or the rearing of animals or both. Aceramic Neolithic groups are more rare outside Western Asia. Aceramic Neolithic villages had many attributes of agricultural communities: large settlement size, substantial architecture, long settlement duration, intensive harvesting of seeds with sickles, equipment and facilities for storing and grinding seeds, and containers. Morphological evidence for domestication of plants comes only from Middle PPNB (Pre-Pottery Neolithic B), and by Late PPNB some animals, notably goats, were domesticated or at least managed in most of the sites.
