The Eruption of Vesuvius [PDF]

open access: yesNature, 1906
YESTERDAY I ascended the cone of Vesuvius up to the crater, being, I suppose, one of the first climbers after the eruption. The ascent was made from Torre Annunziata witnout any difficulties, but care had to be taken to avoid the courses of the avalanches of stones and ashes rushing from the cone and spreading over the slopes more than half a mile from

Radiative and climate impacts of a large volcanic eruption during stratospheric sulfur geoengineering

open access: yes, 2015
. Both explosive volcanic eruptions, which emit sulfur dioxide into the stratosphere, and stratospheric geoengineering via sulfur injections can potentially cool the climate by increasing the amount of scattering particles in the atmosphere.

Restoration of human tooth enamel

open access: yesBMEMat, EarlyView.
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Mesial Migration of Lower Molars in Relation to Facial Growth and Eruption

open access: yesAustralasian Orthodontic Journal, 1996
Mesial migration of teeth in the huccal segments is a well recognised phenomenon in the human dentition. Its aetiology is not fully understood. It has heen suggested that it is, to some extent, dependent on growth changes in the lower face.

Polymorphous Light Eruption.

open access: yesJournal of Investigative Dermatology, 1987
Polymorphous light eruption (PLE) is a common photodermatosis of unknown etiology. It afflicts mainly fair-skinned patients, with a preponderance of young females. There is, however, no absolute restriction as to age, sex, or race. Clinical variants include the papular, vesiculo-bullous, and hemorrhagic variety, as well as plaque, erythema multiforme ...

The magnitude and impact of the Youngest Toba Tuff super-eruption

open access: yesFrontiers in Earth Science, 2014
Super-eruptions, orders of magnitude larger than eruptions experienced in historic times, have devastated wide areas by pyroclastic flows, covered continent-size areas by ash fallout, and injected large quantities of aerosols into the stratosphere ...

The Customization of Phosphorus Terminal for MXene Materials by Photothermal Effect Toward High‐Performance Zn‐Ion Hybrid Supercapacitors

open access: yesBattery Energy, EarlyView.
This study presents the first report of photoinduced phosphorus‐doped MXene (2.7 at% P) demonstrating exceptional electrochemical performance, where the modified material achieves a remarkable specific capacitance of 500.5 F g−1 through synergistic effects of ─P functional groups and dual reoxidation sites on Ti atoms, while the assembled Zn‐based ...

Observation and Modeling of Hydrothermal Response to the 2015 Eruption at Axial Seamount, Northeast Pacific

open access: yesGeochemistry, Geophysics, Geosystems, 2018
The 2015 eruption at Axial Seamount, an active volcano at a depth of 1500 m in the Northeast Pacific, marked the first time a seafloor eruption was detected and monitored by an in situ cabled observatory—the Cabled Array, which is part of the Ocean ...
