Abstract Recent eruptions of the Shinmoedake volcano, Japan, have provided a valuable opportunity to investigate transition between explosive and effusive eruptions. In October 2017, phreatic/phreatomagmatic explosions occurred. They were followed in March 2018 by phase hybrid activity with simultaneous lava flows then intermittent, Vulcanian-style explosions. Evolution surface phenomena, tempo...

Pumice rafts are considered to be a long-range drifting agent that promotes material exchange and the dispersal of marine species. Large ones can also interfere with vessel navigation have negative impact on social economy ecosystems. Synoptic observations from Multispectral Instrument (MSI) on-board Sentinel-2, spatial resolution up 10 m, provide an excellent means monitor track pumice rafts. ...

The 2021 eruption of Fukutoku-Oka-no-Ba (FOB) in the northwest Pacific on 13 August produced a large volume pumice that drifted westward for ~1300 km to Nansei Islands, Japan, and some extent. In February 2022, with similar characteristics FOB was deposited along Gulf Thailand. clasts Songkhla Province, Thailand, were fine-grained <4 cm size rounded. Most consisted clinopyroxene, plagioclase (a...

This study follows a circular economy approach through the preliminary implementation of coated porous inorganic material (PIM), studied as sustainable controlled release fertilizer, and its application for lettuce Lactuca sativa L. cultivar Chiara growth. The PIM was made pumice scraps that partially replaced clay natural raw material, spent coffee grounds agent, bovine bone ash potassium carb...

The formation of clathrin-coated pits at the plasma membrane requires the concerted action of many different molecules. The real challenge lies in determining the hierarchy of these interactions. We are using assays in both intact and permeabilized cells to dissect the temporal requirements for clathrin-coated vesicle formation, and also to examine the role of phosphorylation of the coat proteins.
