Electrospun Composite Lavandula Angustifolia Mill. Extract/PVP Nanofibers

Macromolecular Materials and Engineering, Volume 311, Issue 2, February 2026.
This study presents novel fast‐dissolving nanofibers electrospun from polyvinylpyrrolidone (PVP) loaded with crude lavender extract. The fibers form an amorphous solid dispersion, disintegrate within 1.5 s, and release 70%–90% of their payload within 5 min, significantly outperforming the pure extract.

A finite-strain hyperviscoplastic model and undrained triaxial tests of peat

, 2017
This paper presents a finite-strain hyperviscoplastic constitutive model within a thermodynamically consistent framework for peat which was categorised as a material with both rate-dependent and thermodynamic equilibrium hysteresis based on the data ...

Separable triaxial potential-density pairs in MOND

, 2012
We study mass models that correspond to MOND (triaxial) potentials for which the Hamilton-Jacobi equation separates in ellipsoidal coordinates. The problem is first discussed in the simpler case of deep-MOND systems, and then generalized to the full MOND

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

Fractal Characteristics and Energy Evolution Analysis of Rocks under True Triaxial Unloading Conditions

Fractal and Fractional
To investigate the mechanical properties and energy evolution laws of rocks under true triaxial unloading conditions, a study was conducted using a true triaxial rock testing system on three different types of rocks: coal, sandy mudstone, and siltstone ...

The Impact of Soil Anisotropy on Surface Settlements Induced by Tunnelling: A Revealing Parametric Study and Nomogram Development to Improve Modelling Practice

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 1218-1228, 10 February 2026.
ABSTRACT Natural soils often exhibit clearly anisotropic mechanical properties, yet this characteristic is frequently overlooked in numerical models due to the practical challenges of determining anisotropic parameters. As a result, the influence of anisotropy remains difficult to anticipate, and engineers have limited tools to incorporate it into ...

Permeability evolution of fractured coal subject to confining stress and true triaxial stress loading: experiment and mathematical model

Frontiers in Earth Science
The accurate elucidation and prediction of coal permeability evolution under stress loading conditions are crucial for coalbed methane production. In this study, flow experiments were conducted on six cylindrical coal samples and four cubic coal samples ...

Bayesian Neural Network Prediction and Uncertainty Analysis of Bio‐Cemented Soil Strength

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 3, Page 1349-1366, 25 February 2026.
ABSTRACT Microbially induced carbonate precipitation (MICP) has emerged as a promising ground improvement technique, with MICP‐treated soils exhibiting substantial enhancements in strength. However, experimental results revealed significant variability in strength outcomes of MICP‐treated soils, even under identical treatment conditions and soil ...

Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

The Next Generation Virgo Cluster Survey. VII. The intrinsic shapes of low-luminosity galaxies in the core of the Virgo cluster, and a comparison with the Local Group

, 2016
(Abridged) We investigate the intrinsic shapes of low-luminosity galaxies in the central 300 kpc of the Virgo cluster using deep imaging obtained as part of the NGVS. We build a sample of nearly 300 red-sequence cluster members in the yet unexplored $-14
