Abstract: A novel laser ablation cell geometry significantly reduces the so-called position effect on high precision and accuracy isotopic measurements by Laser Ablation-Multiple Collector-Inductively Coupled Plasma-Mass Spectrometry (LA-MC-ICP-MS). The peak shape, amplitude and pulse duration of… read more here.

DOI: 10.1080/15248372.2019.1581205
Abstract: ABSTRACT This study examined whether there is a developmental difference in the emergence of an item-position effect in intelligence testing. The item-position effect describes the dependency of the item’s characteristics on the positions of the… read more here.
