Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Frictional Instabilities and Carbonation of Basalts Triggered by Injection of Pressurized H2O- and CO2- Rich Fluids [PDF]

, 2018
The safe application of geological carbon storage depends also on the seismic hazard associated with fluid injection. In this regard, we performed friction experiments using a rotary shear apparatus on precut basalts with variable degree of hydrothermal ...

Towards large scale microwave treatment of ores: Part 2 - Metallurgical testing [PDF]

, 2017
A pilot scale microwave treatment system capable of treating 10-150t/h of material at 10-200kW was designed, constructed and commissioned in order to understand the engineering challenges of microwave-induced fracture of ores at scale and generate large ...

Provenance and Petrological Evolution of Sand Injection Complexes: Insights From Heavy Mineral Analysis in the Paleogene Forearc Succession of the San Joaquin Basin

Basin Research, Volume 38, Issue 3, May–June 2026.
The study of heavy mineral assemblages with statistical analysis resolves provenance signatures and quantifies syn‐emplacement modification of sand injection complexes. Results demonstrate transformative petrological processes, including density‐dependent hydraulic sorting and mechanical grain degradation.

Pasteurization Optimization of Coarse‐Ground Beef During Ohmic Heating: Computer Simulation Analysis

Journal of Food Process Engineering, Volume 49, Issue 5, May 2026.
Temperature uniformity and required pasteurization time were improved using computer simulations for coarse‐ground beef during ohmic heating at 20 kHz by adjusting the electrode thickness and the surrounding temperature. ABSTRACT In this study, an ohmic heating (OH) system operating at 20 kHz was used to evaluate the pasteurization of a coarse‐ground ...

Preparation of respirable nanoparticle agglomerates of the low melting and ductile drug ibuprofen: impact of formulation parameters [PDF]

, 2016
Ductile and low melting point drugs exhibit challenging behaviour during both particle size reduction and spray drying as considerable amount of heat is involved in both processes.

Rock comminution as a source of hydrogen for subglacial ecosystems [PDF]

, 2015
Substantial parts of the beds of glaciers, ice sheets and ice caps are at the pressure melting point. The resulting water harbours diverse subglacial microbial ecosystems capable of affecting global biogeochemical cycles.
