Doing so does not create another version of TAI ; it is instead considered to be creating a better realisation of Terrestrial Time ( TT ).

The instant that the gravitational correction started to be applied serves as the epoch for Barycentric Coordinate Time ( TCB ), Geocentric Coordinate Time ( TCG ), and Terrestrial Time ( TT ).

In 1976 the IAU resolved that the theoretical basis for its current ( 1952 ) standard of Ephemeris Time was non-relativistic, and that therefore, beginning in 1984, Ephemeris Time would be replaced by two relativistic timescales intended to constitute dynamical timescales: Terrestrial Dynamical Time ( TDT ) and Barycentric Dynamical Time ( TDB ).

Thus for clocks on or near the geoid, T < sub > eph </ sub > ( within 2 milliseconds ), but not so closely TCB, can be used as approximations to Terrestrial Time, and via the standard ephemerides T < sub > eph </ sub > is in widespread use.

For practical purposes the length of the ephemeris second can be taken as equal to the length of the second of Barycentric Dynamical Time ( TDB ) or Terrestrial Time ( TT ) or its predecessor TDT.

Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, expanded clay or coconut husk.

However, there was a movement amongst geologists ( particularly Neogene Marine Geologists ) to also include ongoing geological time ( Quaternary ) in the Neogene, while others ( particularly Quaternary Terrestrial Geologists ) insist the Quaternary to be a separate period of distinctly different record.

Terrestrial salamanders catch their prey by rapidly extending a sticky tongue which adheres to the prey, allowing it to be pulled into the mouth.

Tau Ceti may be a search target for the Terrestrial Planet Finder

Historical Julian dates were recorded relative to GMT or Ephemeris Time, but the International Astronomical Union now recommends that Julian Dates be specified in Terrestrial Time, and that when necessary to specify Julian Dates using a different time scale, that the time scale used be indicated when required, such as JD ( UT1 ).

Terrestrial landscapes in which the role of biology in mediating surface processes can be definitively excluded are extremely rare, but may hold important information for understanding the geomorphology of other planets, such as Mars.

On 24 October 2012 Ireland's Analogue Terrestrial signal will be switched off and will be replaced by Saorview which was officially launched on 27 May 2011.

While Terrestrial Planet Finder-C aims to study the planetshine of extrasolar planets, Darwin and Terrestrial Planet Finder-I will search for thermal infrared light that is reradiated ( rather than scattered ) by the planet, and most astronomers would not consider that to be planetshine.

It can also be rationalised as making the average length of the Martian week close to the average length of the Terrestrial week, although it must be remembered that 28 Earth days is roughly equal to 27 + 1 / 4 Martian sols and not 27 + 5 / 6 Martian sols.

Coming to the end of his tenure at the Department of Communications, Marine and Natural Resources and before the reshuffle after the general election in May 2007 his department pursued the resurrection of Digital Terrestrial Television following its failure to be established under the Broadcasting Act 2001 due to unfavourable economic conditions for venture capital around the DTT market in many countries in 2001.

The Exalted of Creation can be divided into two categories: Terrestrial Exalted and Celestial Exalted.

Elementals can be summoned through Terrestrial Circle Sorcery, however, unlike demons, powerful elementals often have designated proxies who can be sent to respond to the summoning in their stead.

The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is, subject to the caveats explained below, defined as the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface.

Terrestrial ecosystems are subject to similarly adverse impacts from eutrophication.

After the resurrection, spirits are assigned " permanently " to three degrees of heavenly glory –– Celestial, Terrestrial, and Telestial ––( 1 Cor 15: 44-42 ; Doctrine and Covenants, Section 76 ) or are cast with Satan into Outer Darkness.

where d is the number of days since 1 January 2000 00: 00: 00 in the Terrestrial Time scale used in astronomical ephemerides ; for Universal Time ( UT ) add the following approximate correction to d:

where N is an integer, starting with 0 for the first new moon in the year 2000, and that is incremented by 1 for each successive synodic month ; and the result d is the number of days ( and fractions ) since 2000-01-01 00: 00: 00 reckoned in the time scale known as Terrestrial Time ( TT ) used in ephemerides.

The book described the Island of California as being west of the Indies, " very close to the side of the Terrestrial Paradise ; and it is peopled by black women, without any man among them, for they live in the manner of Amazons.

DVB-T is an abbreviation for Digital Video Broadcasting — Terrestrial ; it is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 and first broadcast in the UK in 1998.

Terrestrial species generally have tiny traps ( sometimes as small as 0. 2 mm ) with a broad beak-like structure extending and curving down over the entrance ; this forms a passageway to the trapdoor and may help prevent the trapping and ingestion of inorganic particles.

While less powerful, Terrestrial Exalted, or Dragon-Blooded, can pass on their Exaltation to their children, much like one would pass on other genetic features.

* 12 years — length of one cycle through the Chinese zodiac ( Terrestrial branch )

* 60 years – length of one full cycle ( Celestial stem / Terrestrial branch ) in the Chinese calendar

) After these factors have been taken into account, deviations between the observed arrival times and predictions made using these parameters can be found and attributed to one of three possibilities: intrinsic variations in the spin period of the pulsar, errors in the realization of Terrestrial Time against which arrival times were measured, or the presence of background gravitational waves.

Terrestrial microwave vehicles can usually be identified by their masts which can be extended up to 50 feet ( 15 m ) in the air ( to allow line-of-sight with the station's receiver antennas ), while satellite trucks normally use a dish that points skywards towards one of the geostationary communications satellites.

They were announced as being one of the channel providers providing DVB-H channels in a 16 channel trial of the technology in Oxford, a system which would have carried Chart Show TV, and were said to be one of the parties involved in bidding for a low-bandwidth, 18 hour a day stream on the UK's Digital Terrestrial Television system in November 2005.
