The 1970 eruption on Deception Island (Antarctica): eruptive dynamics and implications for volcanic hazards

Journal of the Geological Society, 2014
In the southern winter of 1970, a phreatomagmatic eruption occurred in the northern part of Deception Island (South Shetland Archipelago, Antarctic Peninsula). The eruption, with no eye-witnesses to the event, occurred in the same general area as the 1967 eruption, but with new, more widely distributed vents.

A general and green approach of pH‐sensitive ZIF‐67 for encapsulating active substances

Smart Molecules, EarlyView.
Zeolitic imidazolate framework‐67 (ZIF‐67) was successfully synthesized in deionized water for 2 h in this work; meanwhile, various active substances could be encapsulated in one‐pot with the same process, resulting in high loading rates. The study delved into the growth mechanism, morphological difference and loading capacity.

Structure and Dynamics of Erupting Solar Prominences Using the Rolling Hough Transform: Toward a Feature-oriented Classification

The Astrophysical Journal
The classification of solar prominences has proven to be challenging, due to their diverse morphologies and dynamical behavior. Complexity is heightened when considering eruptive prominences, where the dynamics demand methods capable of capturing ...

Modelling of bubble nucleation in trachy-phonolitic magmas: implications for the dynamics of ash-rich eruptions [PDF]

, 2012
Nucleation of water gas bubbles in trachyphonolitic magmatic melts has been investigated integrating theory and numerical modelling with decompression experiments and analysis of natural ash samples of explosive eruptions.

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Estimation of Klyuchevskoy Volcano Activity in 2023 based on the SESL’09 technique [PDF]

E3S Web of Conferences
In October 2023, Klyuchevskoy volcano (Kamchatka, Russia) erupted, when the height of the ash column reached ~15 km. The eruption was preceded by seismic activity.

Media‐Dependent Growth, Stress Responses, and Metal Accumulation Patterns in Azolla imbricata (Roxb.) Nakai Exposed to As, Cd, Cu, Pb, and Zn: Individual and Combination Effects (Synergistic, Antagonistic, and Additive)

Environmental Toxicology, EarlyView.
ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.

Multifractality in local geomagnetic field at Etna volcano, Sicily (southern Italy) [PDF]

Natural Hazards and Earth System Sciences, 2005
We applied the Multifractal Detrended Fluctuation Analysis (MF-DFA), which allows to detect multifractality in nonstationary signals, to the hourly means of local geomagnetic field recorded at Mt. Etna volcano (southern Italy).

Machine Learning Insights into the Last 400 Years of Etna Lateral Eruptions from Historical Volcanological Data

Geosciences
Volcanic hazard assessment is generally based on past eruptive behavior, assuming that previous activity is representative of future activity. Hazard assessment can be supported by Artificial Intelligence (AI) techniques, such as machine learning, which ...

Mycosis Fungoides Is a Proliferation of Multiple Mutational Subclones

The Journal of Dermatology, EarlyView.
ABSTRACT Mycosis fungoides (MF) is a unique type of lymphoma with an excellent prognosis presenting with a wide variety of clinical and histological findings. Recent sophisticated research techniques have revealed that very slow changes in the clinical and histological pictures of one patient over time are due to intratumoral heterogeneity.
