Closed‐form solutions for dynamic punching shear assessment in flat slabs subjected to sudden column removal

open access: yesStructural Concrete, EarlyView.
Abstract Simplified closed‐form equations are commonly used in structural design to prevent punching shear failures of concrete flat slabs supported on columns in permanent and transient situations, whereas more advanced methods are generally used in verifications at accidental design situations due to the lack of suitable equivalent approaches ...

Near‐field blast behavior of ultra‐high‐performance concrete slabs: Parametric analysis and calibration of the UFC‐3‐340 predictive model

open access: yesStructural Concrete, EarlyView.
Abstract Blast loads impose extreme, short‐duration pressures that can cause severe structural damage and compromise safety, a crucial aspect in critical infrastructure, including nuclear facilities. Whereas ultra‐high‐performance concrete (UHPC) offers superior blast resistance compared to conventional concrete (CC) and high‐performance concrete (HPC),

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Mechanistic scaling of twig allometry and crown architecture in Scots pine: implications for moose browse availability

open access: yesWildlife Biology, EarlyView.
Balancing moose Alces alces populations with forest production objectives remains a major challenge in Swedish forestry. We developed a mechanistic, data‐driven model of browse availability in Scots pine Pinus sylvestris saplings by linking shoot‐level allometry, crown architecture, and tree height development.

High‐resolution monochromator for the 8.41 keV 169Tm nuclear resonance

open access: yesJournal of Synchrotron Radiation, EarlyView.
A high‐resolution monochromator for the 8.41 keV 169Tm nuclear resonance is presented enabling nuclear resonant scattering on Tm compounds at PETRA III beamline P01. Hyperfine parameters and phonon densities of states of metallic Tm and Tm2O3 are studied.Rare‐earth elements are key components in a wide range of functional materials, including solid ...
