A Geographic Information Systems Approach to the 19th Century Excavation of Brixham Cavern, Devon, England
The oldest known spatially-explicit archaeological excavation, conducted in Brixham cave, Devon, in 1858, is reconstructed using geographic information systems technology. Two dimensional plots of individual fossil taxa and flint artefacts demonstrate the utility of the technique for elucidating taphonomy and palaeobiology.The cave served as a den for hibernating brown bears, as a den for hyena...
متن کامل3D spectroscopy of merger Seyfert galaxy Mrk 334: nuclear starburst, superwind and the circumnuclear cavern
We are presenting new results on kinematics and structure of the Mrk 334 Seyfert galaxy. Panoramic (3D) spectroscopy is performed at the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences using the MPFS integral-field spectrograph and scanning Fabry–Pérot interferometer. The deep images have revealed that Mrk 334 is observed during the final stage of its m...

متن کاملLead shielding efficiency from the gamma background measurements in the salt cavern of the Polkowice–Sieroszowice copper mine
The studies of lead shielding efficiency from the gamma background measurements were performed in the salt cavern of the copper mine - a site considered for an underground laboratory. Within the energy range of 50-2700 keV, the measured gamma-ray count rates normalized to the mass of the high-purity detectors germanium crystal are 5.93 and 6.32 s-1kg-1 for the used low-background and portable s...
