New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

Geostandards and Geoanalytical Research, EarlyView.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Primary and Secondary Grzybowski’s Generalized Eruptive Keratoacanthoma: A New Perspective on Management, Clinical Features, and Prognosis

International Journal of Dermatology, EarlyView.
ABSTRACT Grzybowski's generalized eruptive keratoacanthoma (GEKA) is a rare variant of keratoacanthomas, characterized by hundreds to thousands of lesions, accompanied by pruritus, mucosal involvement, and comorbidities. Our aim was to analyze the clinical presentation, associated comorbidities, treatment strategies, and outcomes of GEKA.

Basaltic impact melts in the Apollo collections: How many impacts and which events are recorded? [PDF]

Many of the rocks in the Apollo collections from the lunar highlands are impact melt breccias of basaltic bulk composition. They are known by a variety of names including low-K Fra Mauro basalt, VHA basalt, and basaltic impact melts.
