Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

open access: yessteel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

open access: yesStructural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

Enhancing durability of steam‐cured precast concrete culverts using SCMs: A comparative study with delithiated beta spodumene

open access: yesStructural Concrete, EarlyView.
Abstract Steam curing is commonly used to manufacture precast culverts to accelerate early strength development. This study investigates the effect of supplementary cementitious materials (SCMs) on the permeability properties of steam‐cured precast concrete culverts.

Effect of compaction degree on permittivity of water-glass containing moulding sand

open access: yesMetalurgija, 2017
The presented basic research was aimed at determining a correlation between compaction degree of moulding sand and its permittivity εr at 2,45•109 s-1. The measurement results make a basis for mathematical description of a multilayer technological system

Influence of mix design method on the shear capacity of reinforced concrete beams made with high‐quality recycled coarse aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the shear capacity behavior of reinforced concrete (RC) beams without stirrups incorporating recycled coarse aggregate (RCA). An extensive database comprising 269 experimental data points from 40 journal articles published between 2001 and 2025 was compiled, excluding specimens with recycled fine aggregate or fiber ...

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

open access: yesStructural 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 ...

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.
