Comparisons with other single-grain OSL studies across the Iberian central plains suggest that favourable dose saturation properties may be influenced by regional-scale geological controls.The importance of undertaking single-grain OSL dating at Cuesta de la Bajada is also demonstrated by the results of synthetic aliquot experiments, which reveal multiple-grain age offsets of 60–170 ka when unsuitable grain types are inadvertently included in the final age calculations.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.These comparisons support the suitability of our single-grain OSL results and suggest there may be good potential for using quartz supergrains to establish extended-range chronologies at some Middle Pleistocene sites.Having lots of one-on-one time with a romantic interest can open the door to experimentation neither kid is really ready for.Even worse, it seems that the earlier physical relationships start for a teen, the more progressed they are by the high school years.Increase your middle schooler's understanding of organisms, cell parts, microbiology and other life science topics with this kid-friendly study course.Review the short video lessons and then test how well your student understands the material with our multiple-choice quizzes.

Dose saturation represents a fundamental limitation for obtaining finite optically stimulated luminescence (OSL) quartz ages over Middle Pleistocene timescales.

However, there have been relatively few detailed assessments of single-grain OSL properties over high dose ranges.

In this study we investigate extended-range single-grain OSL dating potential at Cuesta de la Bajada, one of the most important Ancient Middle Palaeolithic sites in the Iberian Peninsula.

Spending time with a boyfriend or girlfriend is fun.

Spending lots of time with a boyfriend or girlfriend takes you away from your friends. But middle schoolers who have girlfriends or boyfriends miss out on great platonic relationships.
