Hazard Scenarios Related to Submarine Volcanic‐Hydrothermal Activity and Advanced Monitoring Strategies: A Study Case from the Panarea Volcanic Group (Aeolian Islands, Italy)

Geofluids, Volume 2019, Issue 1, 2019., 2019
Geohazards associated to submarine hydrothermal systems still represent a tricky enigma to face and solve for the scientific community. The poor knowledge of a submarine environment, the rare and scarce monitoring activities, and the expensive and sometimes complicated logistics are the main problems to deal with.

Magmatic Signature in Submarine Hydrothermal Fluids Vented Offshore Ventotene and Zannone Islands (Pontine Archipelago, Central Italy)

Geofluids, Volume 2019, Issue 1, 2019., 2019
Geochemical investigations carried out on submarine hydrothermal fluids vented offshore the Pontine Islands (Tyrrhenian Sea) revealed the existence of gas vents to the W of Zannone Island and SW of Ventotene Island. The geochemical features of the CO2‐rich gas samples show a clear mantle‐derived signature with 3He/4He of 3.72‐3.75 Ra and 1.33 Ra at ...

The Time‐Space Joint Response Characteristics of AE‐UT under Step Loading and Its Application

Shock and Vibration, Volume 2018, Issue 1, 2018., 2018
The acoustic emission (AE) and ultrasonic (UT) simultaneous monitoring program is designed using concrete samples under step loading. The time‐varying response characteristics of AE‐UT are studied and the cross‐correlation analysis between AE‐UT parameters is obtained. Moreover, the joint response of UT‐AE spatial distribution field is analyzed, and an

Spatial and Temporal Distribution Law and Influencing Factors of the Mining‐Induced Deformation and Failure of Gas Boreholes

Advances in Materials Science and Engineering, Volume 2018, Issue 1, 2018., 2018
Because gas boreholes are easy to damage by integrated coal mining and gas exploration, based on the practice of relieving pressure in deep thin coal seams in the Huainan mining area, a multidimensional coupling numerical simulation method was used to reveal the space‐time evolution characteristics and influence factors of fracture deformation of gob ...

Progress of the international H-mode power threshold database activity

, 2002
The International Global H-mode Threshold Database has been revised and cleaned from inadequate data for some tokamaks. This significantly reduces the scatter for the corresponding datasets.

Geofluid Systems of Koryaksky‐Avachinsky Volcanoes (Kamchatka, Russia)

Geofluids, Volume 2017, Issue 1, 2017., 2017
The Koryaksky‐Avachinsky volcanogenic basin, which has an area of 2530 km2, is located 25 km from Petropavlovsk‐Kamchatsky City and includes five Quaternary volcanoes (two of which, Avachinsky (2750 masl) and Koryaksky (3456 masl), are active), and is located within a depression that has formed atop Cretaceous basement rocks.

Interaction time and beam diameter effects on the conduction mode limit [PDF]

, 2012
Laser welding has two distinctive modes: keyhole and conduction mode. Keyhole mode is characterized by deep penetration and high welding speeds, while conduction mode has higher quality welds with no defects or spatter.

Spatial mode switchable, wavelength tunable erbium doped fiber laser incorporating a spatial light modulator [PDF]

, 2014
We present a 2-mode group, switchable spatial mode erbium doped fiber laser incorporating a spatial light modulator. The laser wavelength can be tuned using an intra-cavity wavelength selective filter and provides >10dB extinction ratio between LP01 ...
