An explosive-intrusive subglacial rhyolite eruption at Dalakvisl, Torfajokull, Iceland

, 2008
This paper describes unusual rhyolitic deposits at Dalakvisl, Torfajokull, Iceland that were emplaced during a Quaternary subglacial eruption. Despite its small volume (< 0.2 km(3)), the eruption mechanisms were highly variable and involved both ...

Halogen (Cl, F) release during explosive, effusive, and intrusive phases of the 2011 rhyolitic eruption at Cordón Caulle volcano (Chile)

Volcanica, 2019
We investigate sulphur, chlorine and fluorine release during explosive, effusive and intrusive phases the 2011 Cordón Caulle eruption, with a focus on halogen devolatilization. Petrological analysis shows halogen release to have been promoted by isobaric

Eruption Column Modeling of Explosive Volcanism on Venus

Journal of Geophysical Research: Planets
Abstract Volcanism on Venus has never been directly observed, but several measurements indicate present‐day activity. Volcanism could potentially play a role in climatic processes on Venus, especially in the sulfur cycle like on Earth. Observation of volcanic activity is the primary objective of future Venus spacecraft. However, there

Chemical agents to control biofilm formation in step 1 of care—Toothpastes and mouthwashes/concepts and challenges

Periodontology 2000, EarlyView.
Abstract Maintaining optimal oral hygiene is important for overall oral care, ensuring the well‐being of teeth and their surrounding tissues. In addition, it promotes fresh breath and a pleasing smile. A key element of oral self‐care is the daily use of toothpaste during regular brushing.

Arbuscular mycorrhizal fungal (AMF) communities in sand bars associated with Ipomoea pes‐caprae: a promising strategy for petroleum spill bioremediation in coastal dunes

Restoration Ecology, EarlyView.
Abstract Introduction Polycyclic aromatic hydrocarbons (PAHs), a class of petroleum‐derived compounds known for causing cellular damage and for their recalcitrant behavior, severely limit effective biodegradation. Arbuscular mycorrhizal fungi (AMF) from oil‐contaminated environments can mitigate PAH‐related stress on host plants, highlighting the ...

The Painterly Materiality of Clouds in Antony and Cleopatra and Hamlet

Renaissance Studies, EarlyView.
Abstract This article examines the cloud‐gazing scenes in Antony and Cleopatra and Hamlet through the lens of early modern artistic theory and material practices, particularly the art of limning. Building upon existing philosophical and poetic interpretations of Shakespearean clouds as metaphors for ephemerality and memory, the essay argues that the ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which
