Foaming Processes and Properties of Geopolymer Foam Concrete

Geopolymer foam concrete (GFC) is created by incorporating pores into geopolymer slurry or mortar. The functional and mechanical properties, such as thermal insulation, compressive strength, and density, are influenced by the characteristics of the pores and the properties of their walls.

Emotions in Meaning‐Making: Toward a Sociological Theory of Cathexis

Sociological Forum, EarlyView.
ABSTRACT The role of emotion in meaning‐making remains undertheorized in cultural sociology. This article argues that emotions and affect are intrinsic to meaning‐making and proposes cathexis—the attachment of emotions generated in social interaction to objects, symbols, and ideas—as the fundamental mechanism by which emotions co‐constitute cultural ...

Curvature in spinfoams

, 2011
We consider spinfoam quantum gravity. We show in a simple case that the amplitude projects over a nontrivial (curved) classical geometry. This suggests that, at least for spinfoams without bubbles and for large values of the boundary spins, the amplitude

PFAS Vadose Zone Mass Discharge at an AFFF‐Impacted Site: 1. Validation Based on a Multiple Lines‐of‐Evidence Approach

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Questions have recently been raised about the suitability of using porewater samples collected with suction lysimeters to estimate per‐ and polyfluoroalkyl substances (PFAS) mass discharge in the vadose zone. Multiple lines of evidence were evaluated to determine if porewater samples collected during a data gaps investigation in the former ...

Telecological Collapse: The Inevitability of Climate Breakdown in the Transmedial Podcast Drama Forest 404

Future Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT This paper presents a close‐hearing analysis of Forest 404, a transmedial audio drama that was released to BBC Sounds in 2019. Despite the drama's eco‐dystopian critique of teleological ‘progress’ narratives (that enable and perpetuate the destruction of the natural world), I argue that the series ultimately propagates a sense of inevitability

Performance of sustainable lightweight foam concrete with synthetic micro and macro fibers as reinforcement

Journal of Materials and Engineering Structures, 2023
In the current research, lightweight foam concrete blocks made from recycled concrete powder, reinforced with plastic macro fibers and polypropylene micro fibers have been proposed as sustainable concrete approach. By adding Recycled Concrete Powder (RCP)

Spin Foam Models of Riemannian Quantum Gravity

, 2002
Using numerical calculations, we compare three versions of the Barrett-Crane model of 4-dimensional Riemannian quantum gravity. In the version with face and edge amplitudes as described by De Pietri, Freidel, Krasnov, and Rovelli, we show the partition ...

Cistanche tubulosa Extract Protects Cast Immobilization‐Induced Declines of Muscle Strength and Muscle Mass

Traditional &Kampo Medicine, Volume 13, Issue 1, April 2026.
ABSTRACT Aim One of the effects of Cistanche herb is described in the Chinese Pharmacopoeia as for lack of strength in muscles and bones. However, concrete evidence of this herb for muscle strength has been hardly reported. The present study aimed to clarify the effects of 30% ethanolic extract of Cistanche tubulosa fleshy stem on muscle strength and ...

Protein Energy Malnutrition: Opportunities for Cold Plasma Technologies

Food Frontiers, Volume 7, Issue 2, March 2026.
Protein energy malnutrition (PEM) is a major global health concern driven by biological, environmental, and nutritional factors, including gut microbiota imbalance and low protein intake. Cold atmospheric plasma technologies offer promising, sustainable solutions by improving food security, enhancing protein quality and absorption, and modulating gut ...
