A paraboloidal sparker seismic source

, 1993
A marine sparker seismic source is presented, in which the electrical discharges take place at the focus of a paraboloidal reflecting surface, in order to obtain a downward-oriented, approximately plane acoustic wavefront. This source, here compared with

Do Marine Protected Areas Reduce Poverty? A Systematic Review and Critical Evidence Synthesis of Socioeconomic Outcomes in Southeast Asian Coastal Communities

Sustainable Development, EarlyView.
ABSTRACT Marine Protected Areas (MPAs) are widely recognised as a key strategy for conserving marine biodiversity while advancing sustainable development. Beyond ecological conservation, MPAs are increasingly expected to improve livelihoods and reduce poverty among coastal communities that depend on marine resources.

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

Structural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Seismic Inversion and Source Rock Evaluation on Jurassic Organic Rich Intervals in the Scotian Basin, Nova Scotia

, 2017
Source rocks are a key element of a petroleum system and have been identified as a risk in the Scotian Basin, offshore Nova Scotia, Canada. There have been 24 significant hydrocarbon discoveries, including eight commercial discoveries since 1967 in the ...

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

Structural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Contribution of dowel action to interfacial shear transfer in flat joints with unbonded posttensioned bars for precast segmental bridges

Structural Concrete, EarlyView.
Abstract Dry joints are widely used in precast segmental bridge construction because they simplify assembly and accelerate erection. Incorporating fasteners crossing flat dry joints represents an innovative configuration for this type of connection.
