Across the Great Divide tour
The Across the Great Divide tour was a concert tour by Australian alternative rock bands Powderfinger and Silverchair in 2007.
The tour featured concerts in 26 towns across Australia and multiple shows in New Zealand.
According to Powderfinger frontman Bernard Fanning, the aim of the tour was to" show[ that] both bands are behind the idea of reconciliation."
Both bands aimed to increase awareness of the efforts of Reconciliation Australia to reduce the current 17- year gap in life expectancy between the average Australian life and that of Indigenous Australians.
A triple DVD set was released with the same title as the tour on 1 December 2007 with the Melbourne performances for both bands and backstage occurrences from the tour.
Fermi Gamma-ray Space Telescope
The Fermi Gamma-ray Space Telescope( FGST), formerly called the Gamma-ray Large Area Space Telescope( GLAST), is a space observatory being used to perform gamma-ray astronomy observations from low Earth orbit.
Its main instrument is the Large Area Telescope( LAT), with which astronomers mostly intend to perform an all- sky survey studying astrophysical and cosmological phenomena such as active galactic nuclei, pulsars, other high- energy sources and dark matter.
Another instrument aboard Fermi, the Gamma-ray Burst Monitor( GBM; formerly GLAST Burst Monitor), is being used to study gamma-ray bursts.
Fermi was launched on 11 June 2008 at 16:05 UTC aboard a Delta II 7920- H rocket.
The mission is a joint venture of NASA, the United States Department of Energy, and government agencies in France, Germany, Italy, Japan, and Sweden, becoming the most sensitive gamma-ray telescope on orbit, succeeding INTEGRAL.
Gamma Ray (EP)
Gamma Ray is the debut EP by Gamma Ray, a musical project by former Kyuss guitarist Josh Homme, released in 1996 by Man's Ruin Records.
After the breakup of Kyuss in 1995, Homme recorded the Gamma Ray material in Seattle with producer Chris Goss, bassist Van Conner, and drummer Victor Indrizzo.
Former Kyuss singer John Garcia contributed backing vocals to the track" Born to Hula".
After the release of the EP, Homme received a cease and desist order because the name Gamma Ray was already in use by a German power metal band.
He changed the name of the project to Queens of the Stone Age, and both of the" Gamma Ray" tracks were re-released the following year by Man's Ruin on the" Kyuss/ Queens of the Stone Age" split EP, which featured some of the final studio recordings by Kyuss and debuted the" Queens of the Stone Age" moniker for Homme's new project.
The split EP also included a third track from the" Gamma Ray" recording sessions," Spiders and Vinegaroons".
Both tracks from the" Gamma Ray" EP were later re-recorded by Queens of the Stone Age.
" If Only Everything" was re-recorded under the shortened title" If Only" for Queens of the Stone Age's debut album in 1998, while" Born to Hula" was re-recorded and appeared as a B-side on" The Lost Art of Keeping a Secret" single from the band's 2000 album" Rated R".

I Gufi
I Gufi(" The Owls", also spelled just as Gufi) was an Italian musical and comedy ensamble, mainly successful in the second half of the 1960s.
Gamma ray logging
Gamma ray logging is a method of measuring naturally occurring gamma radiation to characterize the rock or sediment in a borehole or drill hole.
It is a wireline logging method used in mining, mineral exploration, water- well drilling, for formation evaluation in oil and gas well drilling and for other related purposes.
Different types of rock emit different amounts and different spectra of natural gamma radiation.
In particular, shales usually emit more gamma rays than other sedimentary rocks, such as sandstone, gypsum, salt, coal, dolomite, or limestone because radioactive potassium is a common component in their clay content, and because the cation exchange capacity of clay causes them to adsorb uranium and thorium.
This difference in radioactivity between shales and sandstones/ carbonate rocks allows the gamma ray tool to distinguish between shales and non-shales.
But it can not distinguish between carbonates and sandstone as they both have similar deflections on the gamma ray log.
Thus gamma ray logs can not be said to make good lithological logs by themselves, but in practice, gamma ray logs are compared side- by- side with stratigraphic logs.
The gamma ray log, like other types of well logging, is done by lowering an instrument down the drill hole and recording gamma radiation variation with depth.
In the United States, the device most commonly records measurements at 1/ 2- foot intervals.
Gamma radiation is usually recorded in API units, a measurement originated by the petroleum industry.
Gamma rays attenuate according to the diameter of the borehole mainly because of the properties of the fluid filling the borehole, but because gamma logs are generally used in a qualitative way, amplitude corrections are usually not necessary.
Three elements and their decay chains are responsible for the radiation emitted by rock: potassium, thorium and uranium.
Shales often contain potassium as part of their clay content and tend to adsorb uranium and thorium as well.
A common gamma-ray log records the total radiation and can not distinguish between the radioactive elements, while a spectral gamma ray log( see below) can.
For standard gamma-ray logs, the measured value of gamma-ray radiation is calculated from concentration of uranium in ppm, thorium in ppm, and potassium in weight percent: e.g., GR API= 8 × uranium concentration in ppm+ 4 × thorium concentration in ppm+ 16 × potassium concentration in weight percent.
Due to the weighted nature of uranium concentration in the GR API calculation, anomalous concentrations of uranium can cause clean sand reservoirs to appear shaley.
For this reason, spectral gamma ray is used to provide an individual reading for each element so that anomalous concentrations can be found and properly interpreted.
An advantage of the gamma log over some other types of well logs is that it works through the steel and cement walls of cased boreholes.
Although concrete and steel absorb some of the gamma radiation, enough travels through the steel and cement to allow for qualitative determinations.
In some places, non-shales exhibit elevated levels of gamma radiation.
For instance, sandstones can contain uranium minerals, potassium feldspar, clay filling, or lithic fragments that cause the rock to have higher than usual gamma readings.
Coal and dolomite may contain adsorbed uranium.
Evaporite deposits may contain potassium minerals such as sylvite and carnallite.
When this is the case, spectral gamma ray logging should be done to identify the source of these anomalies.
DracoVirgo
DracoVirgo is a Japanese band, and formed in 2017.
Gamma Ray (band)
Gamma Ray is a heavy metal band from Hamburg, northern Germany, founded and fronted by Kai Hansen after his departure from the German power metal band Helloween.
He is the band's lead vocalist, guitarist and chief songwriter.
Between 1990 and 2014, Gamma Ray recorded eleven studio albums.
Gamma-Ray Imaging Spectrometer
The Gamma- Ray Imaging Spectrometer( GRIS) was a gamma-ray spectrometer instrument on a balloon- borne airborne observatory.
It used germanium detectors to achieve high resolution spectroscopy.
GRIS was operated from 1988 to 1995 by NASA's Goddard Space Flight Center, which called it" arguably one of the most successful gamma- ray balloon programs in history".
Dan Zimmermann
Daniel Hans Erwin Zimmermann( born 30 October 1966 in Nürnberg, Germany) is a retired heavy metal drummer.
Dan is best known as having been the drummer of German power metal bands Gamma Ray and Freedom Call from 1997 to 2012.
He was a founding member of Freedom Call, from which he departed in 2010.
Two years later he also left Gamma Ray, announcing a rest from the music business in 2012.
