Powerful, Weightless, and Free: Reconceptualising Young People's Narratives of Resistance in the Context of Sexual Violence and Exploitation Using Recognition Theory

open access: yesChildren &Society, EarlyView.
ABSTRACT Meeting the needs of young people affected by sexual exploitation, alongside other forms of extra‐familial harm, remains a challenge for social workers, youth workers and other professionals responsible for their safety and well‐being. This paper proposes that to more effectively create safety with/for young people, we must re‐examine how we ...

Reducing frost heave and salt migration in saline soil foundations of channels in seasonal frozen regions using solidification

open access: yesGuan'gai paishui xuebao
【Objective】Saline soils in seasonal frozen regions are often used as channel foundations but are prone to frost heave and salt migration, which can compromise structural stability.

Effects of Static and Dynamic Loads on Frost Heave Deformation of Coarse-Grained Subgrade Soil in Cold Regions

open access: yesApplied Sciences
With the rapid development of high-speed and heavy-haul railways in cold regions, understanding the influence of external loads on the frost heave behavior of subgrade fillings is of great importance.

CALCULATION OF TANGENTIAL FROST HEAVE STRESSES BASED ON PHYSICAL, MECHANICAL AND STRESS-STRAIN BEHAVIOR OF FROZEN SOIL

open access: yesArchitecture and Engineering, 2017
Development of northern territories opens up new opportunities for social and economic development of the society. However, designing construction facilities in such areas is complicated by special features of the severe climate; frost heave of soils is ...

Field frost heave predictions using the segregation potential concept

open access: yes, 1982
The Konrad–Morgenstern theory of frost heave using the segregation potential concept is briefly outlined, and the method of predicting frost heave under field conditions is reviewed. A recent paper by Nixon et al.

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

An integrated experimental-numerical frost heave prediction model

open access: yes, 1993
Structural and geotechnical designs of some civil engineering structures require a prediction of potential frost heave. The present study is a novel approach which combines the experimental technique and numerical modelling to predict frost heave more ...

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, Volume 2026, Issue 6, June 2026.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Quantification of ground surface movements on sorted circles using time‐lapse structure‐from‐motion photogrammetry in a karst cave, Slovenia

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
We present ground surface movements on sorted circles in a karst cave using time‐lapse photogrammetry with accuracies of up to ±2 mm. Data with 3‐hourly resolution revealed average vertical movements of up to 50 mm and horizontal movements of up to 15 mm during individual freeze–thaw cycles.
