Simplified Gravity Load Collapse Dynamic Analysis of Old-Type Reinforced Concrete Frames

Construction Materials
The results of shaking table tests from previous studies on a one-story, two-bay reinforced concrete frame—exhibiting both shear and axial failures—were compared with nonlinear dynamic analyses using simplified models intended to evaluate the collapse ...

Collapse Mechanisms of Nascent and Aged Sea Spray Aerosol Proxy Films

Atmosphere, 2018
Sea spray aerosol (SSA) is highly enriched in marine-derived organic compounds during seasons of high biological productivity, and saturated fatty acids comprise one of the most abundant classes of molecules.

The Impact of Deviation of the Stun Shot from the Ideal Point on Motor Paralysis in Cattle

Animals, 2020
The effect on motor paralysis of a deviation in the stun shot placement from the ideal point on cattle skulls was monitored in 627 bovine animals (271 bulls and 356 cows) stunned with a captive bolt during slaughter in a slaughterhouse.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Dynamic evolution of periodic collapse and carbon impurity distribution at the plasma boundary with magnetic islands on J-TEXT

Nuclear Fusion
Periodic collapses at the edge of Ohmic-mode plasma under Resonant Magnetic Perturbation (RMP) have been observed in the J-TEXT tokamak. These collapses occur following the field penetration.

Collapse Dynamics and Collapse Models [PDF]

Symposium - International Astronomical Union, 1977
Although we now possess a wealth of information about the properties of molecular clouds and the circumstances in which stars form, we still have little direct information about the crucial question of how the material in molecular clouds actually becomes condensed into stars.

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Numerical Investigation of a Dual‐Mode Shape Memory Alloy Stent Enabling Secondary Expansion via Focused Ultrasound: A Potential Strategy for Correcting In‐Stent Restenosis

Advanced Engineering Materials, EarlyView.
This study demonstrates a novel noninvasive strategy to treat in‐stent restenosis using focused ultrasound. A shape memory alloy stent initially expands at body temperature. If restenosis occurs, targeted ultrasound heating thermally actuates the stent, enabling a secondary expansion to reopen the blocked vessel, offering a potential alternative to ...
