Fireside corrosion degradation of ferritic alloys at 600°C in oxy-fired conditions [PDF]

, 2014
This paper reports the results of a study carried out to investigate the effects of simulated coal/biomass combustion conditions on the fireside corrosion. The 1000 h deposit recoat exposure (5 × 200 h cycles) was carried out at 600 °C.

Temporal changes in the internal stresses and pore pressures in a large-scale submarine mass transport deposit

Progress in Earth and Planetary Science, 2018
We examined the temporal changes in the internal stresses and pore fluid pressures of a submarine mass transport deposit (MTD) in the Akkeshi Formation of the Upper Cretaceous–Paleocene Nemuro Group, eastern Hokkaido Island, Japan.

Sedimentation and mobility of PDCs: a reappraisal of ignimbrites’ aspect ratio

Scientific Reports, 2017
The aspect ratio of ignimbrites is a commonly used parameter that has been related to the energy of the parent pyroclastic density currents (PDCs). However this parameter, calculated as the ratio between the average thickness and the average lateral ...

Metal Preservation and Mobilization in Sediments at the TAG Hydrothermal Field, Mid‐Atlantic Ridge

Geochemistry, Geophysics, Geosystems, 2023
At the Trans‐Atlantic Geotraverse hydrothermal field, metalliferous sediments cover extinct hydrothermal mounds and the surrounding seafloor. Here, we report the morphological, mineralogical and geochemical processes that deposit these sediments ...

Intensification of technological processes in drilling and blasting operations during open-cut mining in Kyzylkum region [PDF]

, 2018
Purpose. It is found that for long term standing, the pit bench profile is close to the boundary of the disturbed zone. Therefore, long stability of the bench can be estimated in respect to the size of the disturbed area and the boundary of residual ...

Incorporation of substrate blocks into mass transport deposits: Insights from subsurface and outcrop studies

The Depositional Record
Mass movements are common on the continental slope, affecting not only the subsequent sea floor morphology but often substantially modifying the underlying deposits.

Possible climate preconditioning on submarine landslides along a convergent margin, Nankai Trough (NE Pacific)

Progress in Earth and Planetary Science, 2017
Submarine landslides are major agents of sediment mass transfer from the shallow to deep sea. Due to their rapid emplacement and tsunamigenic potential, such landslides are significant geohazards for society and off- and on-shore infrastructure.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.
