(June 6) Pope Francis urged Bosnia's Muslims, Orthodox and Catholics to put the "barbarity" of war behind them and work together for a peaceful future during his one-day visit to Sarajevo on Saturday.(June 6) Police say one person suffered minor injuries when a strong storm lifted a pickup truck and blew it into a building at a shopping center in southwest Ohio. (May 27) Thousands of Irish citizens gathered at Dublin Castle and exploded with joy when it was revealed 62.1 percent of Irish voters had said "yes" to changing the nation's constitution to allow gay marriage.Assessments of OSL signal composition and the ability to successfully recover a known laboratory dose of 470 Gy support the potential for obtaining high equivalent dose (D estimation over high dose ranges related to (i) thermally transferred signal contributions, (ii) choice of dose-response curve fitting function, and (iii) insufficient dose saturation properties of individual grains.The single-grain D values obtained using the standard quality assurance criteria and novel sensitivity tests are consistent at 2σ, and are in agreement with quartz Ti-centre ages obtained on two of three paired electron spin resonance (ESR) samples collected from Cuesta de la Bajada.
(May 17) As Iraqi government forces continue to battle Islamic militants in Ramadi, a video released by the Iraq's defense ministry allegedly shows Islamic State (IS) positions being attacked by government forces. (May 16) A joint US-Georgian military exercise was underway on Sunday at the Vaziani military base, on the outskirts of the capital Tbilisi.
This enhanced variability may offer the potential to obtain extended-range chronologies exceeding the traditional upper age limits of multiple-grain OSL dating.
However, there have been relatively few detailed assessments of single-grain OSL properties over high dose ranges.
Dose saturation represents a fundamental limitation for obtaining finite optically stimulated luminescence (OSL) quartz ages over Middle Pleistocene timescales.
Single-grain OSL studies typically reveal significant intra- and inter-sample variability in quartz dose saturation properties at the individual grain level.
