Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

Laser &Photonics Reviews, EarlyView.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

Design and analysis of a three-dimensional seismic isolation device for small modular reactor building

Nuclear Engineering and Technology
Seismic isolation in nuclear power plant (NPP) buildings has been infrequently applied using a rubber-based horizontal seismic isolation system (SIS) without vertical isolation under a peak ground acceleration (PGA) of 0.3 g as the seismic design ...

A Parallelized 3D Geomechanical Solver for Fluid‐Induced Fault Slip in Poroelastic Media

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT We present a fully implicit formulation of coupled fluid flow and geomechanics for fluid injection/withdrawal in fractured reservoirs in the context of CO2$\textrm {CO}_2$ storage. Utilizing a Galerkin finite‐element approach, both flow and poroelasticity equations are discretized on a shared three‐dimensional mesh.

Innovative development and structural behavior of hollow columns using inflatable molds

Structural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Advancements and reflections on the implementation of seismic isolation technology in rural buildings

Discover Civil Engineering
Earthquakes are very common, and once they occur, they cause economic losses and casualties. To advance earthquake resistance and disaster mitigation, isolation is employed to decouple the transmission of seismic energy within structures, thereby ...

Lessons for the Next Global Health Crisis: A Qualitative Systematic Review of Women's Experiences of the Perinatal Period During the COVID‐19 Pandemic in Australia

Australian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background During the coronavirus disease of 2019 (COVID‐19) pandemic, pregnant women and new mothers in Australia experienced extreme pandemic societal responses but low SARS‐CoV‐2 incidence. This offers one of the few opportunities internationally to learn from the pandemic's indirect effects on maternal health, informing future policy ...
