Polyurethane foam lightweight concrete: Preparation, CO2 fixation properties and mechanism

open access: yesJournal of CO2 Utilization
To enhance the carbon sequestration of concrete and the mechanical properties of polyurethane foam concrete (PFC), a novel formulation was developed using ordinary Portland cement, basalt stone powder, diphenylmethane diisocyanate, and polyether polyol ...

The multilayered soil-structure seismic interaction and structure vibration mechanism

open access: yesFracture and Structural Integrity, 2020
The morphology of subsoil influences to soil-structure interaction and it makes complex to predict seismic structural stability. The structural elements seismic response associate to soil-structure interaction is required expansive investigation with ...

Seismic soil pile interaction:experimental evidence [PDF]

open access: yes, 2009
The comprehension of the real behaviour of pile foundations under earthquake loading is very important, since it can significantly affect the performance of the superstructure.

Preparation and application conductive concrete from iron tailings to the teaching reform in engineering materials courses

open access: yesScientific Reports
The conversion of iron tailings, a mining solid waste, into conductive concrete aligns with green engineering and supports the development of intelligent construction materials. This study employed a four-factor, four-level orthogonal test to investigate

Frost resistance and micro mechanism of metakaolin and polypropylene fiber modified coastal cement soil

open access: yesJournal of Materials Research and Technology
In order to investigate the effects of metakaolin and polypropylene (PP) fiber on the macroscopic mechanical properties and microscopic mechanisms of cement soil subjected to freeze-thaw cycles, a series of unconfined compressive strength (UCS) and ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Short-term mechanical properties and microstructure of coastal cement soil modified by sugarcane bagasse ash

open access: yesResults in Engineering
Sugarcane bagasse ash is a kind of agricultural waste with a large quantity and good volcanic ash reactivity, it is necessary to find a way to reasonably utilize it to prevent environmental pollution caused by long-term accumulation.

Presentation of analytical solutions for seismically induced tunnel lining forces accounting for soil-structure interaction effects [PDF]

open access: yesGrađevinski Materijali i Konstrukcije, 2014
Recently, as the structural design has shifted to the performance design, seismic design of tunnel structures considering soil-structure interaction becomes more important. The effects of soil-structure interaction should not be overlooked for the reason

Shear Characteristics of Soil—Concrete Structure Interaction Interfaces

open access: yesApplied Sciences, 2022
The shear characteristics of the interfaces between soil and concrete structures are essential for the safety of the structures. In this study, a large-scale direct shear test apparatus was developed to measure the mechanical parameters of soil–concrete ...

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.
