Overcoming Polyatomic Interferences in Sulfur Isotope Measurement Using MC‐ICP‐MS
Geostandards and Geoanalytical Research, EarlyView.Key Points Optimising plasma conditions via the normalised argon index (NAI) reduces polyatomic interferences, allowing accurate sulfur isotope measurement in low‐resolution mode on MC‐ICP‐MS. Low‐resolution mode enhances sensitivity by approximately threefold compared with conventional high‐resolution analysis.

Earth, Planets and Space, 2020 Reconstruction of the eruption history of an active volcano is necessary to elucidate its volcanic activity and to assess the probability of its volcanic eruption. Yokodake volcano in central Japan is the only active volcano among the Yatsugatake volcano

Volatile Transport by Volcanic Plumes on Earth, Venus and Mars [PDF]
, 2012 Explosive volcanic eruptions can produce sustained, buoyant columns of ash and gas in the atmosphere (Fig. 1). Large flood basalt eruptions may also include significant explosive phases that generate eruption columns.

Ash plume properties retrieved from infrared images: a forward and inverse modeling approach
, 2014 We present a coupled fluid-dynamic and electromagnetic model for volcanic ash plumes. In a forward approach, the model is able to simulate the plume dynamics from prescribed input flow conditions and generate the corresponding synthetic thermal infrared (

The Journal of American Culture, EarlyView.ABSTRACT This article examines the use of promotional interviews (“promos”) in American professional wrestling of the 1980s. I argue that promos introduced a vocal modality into a form of sports entertainment that, as Roland Barthes ([1957] 1972) showed in Mythologies, had always been dominated by visual spectacle. I then undertake a focused linguistic

Magmatic volatiles in explosive rhyolitic eruptions
Geophysical Research Letters, 1981 Obsidian clasts in rhyolitic tephra deposits preserve preemption magmatic volatile contents, providing a direct means for determining the volatile content of explosively erupted magmas. Small to moderate volume Plinian eruptions (10−3 to 10−1 km³) appear to be driven by 0.5‐1.0 wt.% volatiles, consisting dominantly of H2O with minor CO2.

JCMS: Journal of Common Market Studies, EarlyView.Abstract Drawing on Laclau and Mouffe's poststructuralist discourse theory, this article critically examines the von der Leyen Commission's agricultural trade policy under the European Green Deal. It elucidates the shift from a dominant neoliberal trade logic to open strategic autonomy, positioning agricultural trade as a foreign policy instrument. The
