Trendelenburg positioning with or without norepinephrine infusion for haemodynamic support in anaesthetised hypovolemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Intraoperative haemorrhage during equine anaesthesia is a rare but potentially fatal complication requiring prompt haemodynamic support. Postural manoeuvres such as Trendelenburg (TL) positioning and vasopressor support augment venous return and improve cardiac output (CO), yet their efficacy in anaesthetised hypovolemic horses ...

The Association of Upper Airway Anatomy and Hypoglossal Nerve Stimulation Response in OSA

The Laryngoscope, EarlyView.
CT‐derived measurements of tongue and craniofacial anatomy were evaluated in adults undergoing hypoglossal nerve stimulation for obstructive sleep apnea. Relative tongue volume was not significantly associated with treatment response. Exploratory analyses suggest that other anatomic features such as hyoid positions or transverse maxillary dimensions ...

Anaerobic Corrosion Phenomena of Cast Iron and Copper in Artificial Groundwater at Elevated Temperature

Materials and Corrosion, EarlyView.
This study examines corrosion of copper and cast iron as candidate canister materials for high‐level radioactive waste disposal in contact with bentonite suspension. The influence of three electrolyte compositions on corrosion behavior under repository‐relevant conditions is assessed.

Anisotropic Initial Damage and Its Effect on Tensile Response of Plain Concrete

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Damage is often described as isotropic, implying that a scalar value describes its initial state. However, the prior micro‐cracking pattern at points of an existing building, that is, the initial damage, may be oriented by a preload. The degradation of the Volume Element due to oriented preloads shall be described as anisotropic and ...

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Assessing and Quantifying Variability Across Vacuum‐Assisted Resin Infusion Variants for Aerospace‐Grade Composite Manufacturing

Polymer Composites, EarlyView.
Radar‐plot comparison of consolidation quality and flexural performance of composite laminates manufactured by six vacuum‐infusion routes, evaluated at the resin‐inlet and vacuum‐port regions. ABSTRACT Conventional vacuum‐assisted resin transfer molding (C‐VARTM) is recognized as a cost‐effective resin infusion technique for manufacturing large‐scale ...

Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

Polymer Composites, EarlyView.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.

Experimental and Numerical Thermo‐Mechanical Characterization of Polylactic Acid Fabricated by Fused Filament Fabrication

Polymer Engineering &Science, EarlyView.
Experimental and numerical framework for characterizing the thermomechanical response of polylactic acid fabricated by fused filament fabrication. ABSTRACT This study investigates the thermomechanical response of polylactic acid (PLA) specimens fabricated by fused filament fabrication (FFF) at two nozzle temperatures (190°C and 230°C), while mechanical
