Research of foam concrete quality by two-stage foam injection method in comparison with classical foam concrete

Technobius
The article presents a method of production of foam concrete, which involves two-stage injection of foam. The proposed method involves improving the pore structure of foam concrete, due to a more uniform distribution of pores throughout the volume of the material.

Unmarked Emotional States and the Affective Anchoring of Continuity

Sociological Forum, EarlyView.
ABSTRACT Narratives around emotions often foreground remarkable episodes that interrupt situations, producing a “rollercoaster” image of emotional life that leaves its stability underdescribed. To analyze the emotional dimension of social continuity, this article theorizes unmarked emotional states (UES): culturally default, interactionally unobtrusive

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 ...
