First absolute dating of Andean hunter-gatherer rock art paintings from North Central Chile
(Springer, 2017)
We report the first absolute dating for rock paintings by Andean hunter-gatherer groups. Analysis by Raman spectrometry of remains of black paintings from the center-north of Chile (30° lat. S) allows for the identification ...
VCD determination of the absolute configuration of stypotriol
(2009)
The absolute configuration of the pentacyclic ichthyotoxin stypotriol, a constituent of Stypopodium zonale, was deduced to be 3S,5R,8R,9R,10S,13S,14S-(-) -1 by vibrational circular dichroism spectroscopy of the derived ...
Scheduling in a two-machine flowshop for the minimization of the mean absolute deviation from a common due date
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This paper addresses the minimization of the mean absolute deviation from a common due date in a two-machine flowshop scheduling problem. We present heuristics that use an algorithm, based on proposed properties, which ...
Potentialities and practical limitations of absolute neutron dosimetry using thin films of uranium and thorium applied to the fission track dating
(Elsevier B.V., 1999-06-01)
Neutron dosimetry using natural uranium and thorium thin films makes possible that mineral dating by the fission-track method can be accomplished, even when poor thermalized neutron facilities are employed. In this case, ...
First archaeointensity reference paleosecular variation curve for South America and its implications for geomagnetism and archaeology
(Cambridge University Press, 2019)
We report comprehensive rock-magnetic and archaeointensity investigations from 21 well-constrained pottery fragments from the Catamarca province of northwest Argentina. The absolute ages of the studied sites are ascertained ...
