Nondestructive Detection of Osmotic Damage in GFRP Boat Hulls Using Active Infrared Thermography Methods

Journal of Marine Science and Engineering
This article presents the application of infrared thermography as a nondestructive testing method (NDT) for detecting osmotic damage in glass-fiber-reinforced polymer (GFRP) and glass-reinforced polymer (GRP) boat hull structures.

Crack Process Investigation in Gears Under Single Tooth Bending Fatigue Condition Using Infrared Thermography and 3D XFEM Numerical Models

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The present study proposes a combined approach of infrared thermography and 3D XFEM numerical models for crack process investigation in mechanical components such as gears. Over the years, fatigue crack analysis based on energy dissipations in the form of heat generated during fatigue tests has been widely reported, although mainly limited to ...

European S2k guidelines for hidradenitis suppurativa/acne inversa Part 1. Epidemiology, diagnosis and clinical assessment

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Updated S2k hidradenitis suppurativa (HS) guidelines provide expert consensus on diagnosis, assessment and comorbidities. Expanded substantially since the 2015 version, they reflect rapid growth in HS literature and aim to improve generalist‐level patient care through evidence‐informed, consensus‐based guidance.

Thermo‐Fluid‐Structural Coupling Analysis of Twin‐Screw Compressor Rotors Under Variable Operating Conditions

Applied Research, Volume 5, Issue 5, October 2026.
A validated thermo‐fluid‐structural coupling framework reveals that rotor von Mises stress exhibits a non‐monotonic trend with discharge pressure, reaching a minimum at 0.3 MPa (3000 rpm)—identifying a structurally optimal operating point that minimizes mechanical loading and extends fatigue life.

The Iseult Coil, a Hybrid RF Coil for the First Human Brain Images at 11.7 T: Receive Performance Comparison With a Twin Coil at 7 T

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Our 8‐Tx/32‐Rx coil is based on two rows of transceiver microstrips intertwined with receive‐only loops. Comparison of the intrinsic SNR at 7 and 11.7 T leads to a 2.2 ratio for the human brain, and 2.75 for a 16‐cm agar sphere, translating into α = 1.5 and 1.95 in the B0α$$ {B}_0^{\alpha } $$‐SNR model, respectively.

Infrared Thermographic Assessment of Fatigue Behavior in Bolted Composite Joints

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 10, Page 4136-4149, October 2026.
ABSTRACT This study investigates the temperature evolution of bolted thick glass fiber reinforced polymer composites during fatigue testing. Three different adherend thicknesses (8, 10, and 12 mm) and three different bolt tightening torques (30, 40, and 50 N ·m were considered to evaluate the effects of adherend thickness and bolt tightening torque on ...
