Terra Indigena Menkragnoti is an indigenous territory created in 1994 in the state of Pará (as part of municipalities of Altamira and São Félix do Xingu) and in Mato Grosso (municipalities of Matupá and Peixoto de Azevedo), Brazil.
Ishmael is a 1992 philosophical novel by Daniel Quinn.
 It examines the mythological thinking at the heart of modern civilization, its effect on ethics, and how this relates to sustainability and societal collapse on the global scale.
 The novel uses a style of Socratic dialogue to deconstruct the notion that humans are the pinnacle of biological evolution.
 It posits that anthropocentrism and several other widely accepted modern ideas are actually cultural myths and that global civilization is enacting these myths with catastrophic consequences.
 The novel was awarded the $500,000 Turner Tomorrow Fellowship Award in 1991, a year before its formal publication.
A planetary civilization or global civilization is a civilization of Type I on Kardashev scale, with energy consumption levels near that of a contemporary terrestrial civilization with an energy capability equivalent to the solar insolation on Earth (between 10 and 10 watts).
 In social aspect the worldwide, global, increasingly interconnected, international, highly technological society.
Jururei is a tiny uncontacted Indian tribe numbering 8-10 people living in the Parque Nacional Pakaas Novas inside the Terra Indigena Uru-Eu-Uaw-Uaw in Rondônia State, Brazil.
 In 2005 their land was invaded by loggers who tried to wipe them out.
 It is not known how many of the tribespeople were killed in the conflict that followed.
 When FUNAI officials visited their only village, it was abandoned and huts were destroyed.
In the history of art, prehistoric art is all art produced in preliterate, prehistorical cultures beginning somewhere in very late geological history, and generally continuing until that culture either develops writing or other methods of record-keeping, or makes significant contact with another culture that has, and that makes some record of major historical events.
 At this point ancient art begins, for the older literate cultures.
 The end-date for what is covered by the term thus varies greatly between different parts of the world.
Terra Indigena Xinane Isolados is an indigenous territory in Acre State, Brazil, which has been dedicated to uncontacted Indians.
A fiber optic coupler is a device used in optical fiber systems with one or more input fibers and one or several output fibers.
 Light entering an input fiber can appear at one or more outputs and its power distribution potentially depending on the wavelength and polarization.
 Such couplers can be fabricated in different ways, for example by thermally fusing fibers so that their cores get into intimate contact.
 If all involved fibers are single-mode (supporting only a single mode per polarization direction for a given wavelength), there are certain physical restrictions on the performance of the coupler.
 In particular, it is not possible to combine two or more inputs of the same optical frequency into one single-polarization output without significant excess losses.
 However, such a restriction does not occur for different input wavelengths: there are couplers that can combine two inputs at different wavelengths into one output without exhibiting significant losses.
 Wavelength-sensitive couplers are used as multiplexers in wavelength-division multiplexing (WDM) telecom systems to combine several input channels with different wavelengths, or to separate channels.
Terra Indigena Uru-Eu-Uaw-Uaw is an indigenous territory located in central Rondônia, Brazil.
 It has a contacted Indian population of around 168 people belonging to Amondaua, Uru Pa In, Juma, and Jupaú tribes (as of 2002).
 There remains an unknown number of uncontacted Indians who belongs to 4 to 6 different tribes like Jururei, Yvyraparaquara, Uru Pa In (uncontacted bands) and Parakua.
 The uncontacted population was estimated at somewhere between 1,000 and 1,200 in 1986, but it has declined very steeply in the recent decades.
 It is one of the most unsafe indigenous territories in Brazil and is regularly invaded by loggers and ranchers.
 The Jururei tribe was subjected to mass killings in 2003 and 2005.
 Most of the Jupaú are now Christian, while the other tribes are entirely animist.
The Kararao are a tribe of the Kayapo nation of Brazil.
 As of 2004, contacted Kararao numbered only 29 individuals and a further 50 or so remain uncontacted.
 The Kararao live in the Terra Indigena Kararahô in Pará (Area-3308.37 km²).
Uncontacted peoples, also referred to as isolated peoples or lost tribes, are communities who live, or have lived, either by choice (peoples living in voluntary isolation) or by circumstance, without significant contact with global civilization.
 Few people have remained totally uncontacted by global civilization.
 Indigenous rights activists call for such groups to be left alone, stating that it will interfere with their right to self-determination.
