Comparative study of processing environments in fiber laser texturing of CFRP for enhanced adhesive bonding strength

Laser surface texturing of carbon fiber reinforced polymer (CFRP) surfaces serves as a viable option for achieving improved surface preparation for adhesive bonding; however, CFRP surfaces may retain defects that can affect the service performance of the joint. In the present stu...

Pipeline infrastructure for hydrogen transport in the United States

Pipeline infrastructure is crucial for regional hydrogen transport. However, existing pipeline models have remarkably underestimated the construction-related material and labor costs compared to U.S. historical data. To cope with this problem and establish sustainable infrastruct...

Fear of Falling and Its Association with Lower Limb Strength and Balance Control in Elderly Day-Care Center Users

This cross-sectional study examined associations between lower limb strength, mobility, balance control, and fear of falling (FOF) among older adults attending community-based day-care centers. Seventy-three participants aged ≥65 years underwent assessments of knee extension stre...

Compact Quasi-Metric Spaces Are Expand-Contract Plastic

On a totally bounded metric space, every non-contractive self-map is an isometry (Freudenthal–Hurewicz; Naimpally–Piotrowski–Wingler). For quasi-metric spaces, taken T1 throughout, this fails: Zavarzina gave a hereditarily precompact counterexample (Carpathian Math. Publ. 15(2),...

Green Extraction of Lignin From Date Palm ( Phoenix dactylifera L.) Seed Waste and Its Integration Into Alginate‐Based Films With Improved Moisture Resistance, Antioxidant Capacity, and Surface Hydrophobicity for Food Packaging Applications

ABSTRACT The aim of the current study was to extract lignin‐rich fraction from date palm ( Phoenix dactylifera L.) seeds and evaluate its application as a filler in sodium alginate‐based films for food packaging applications. Lignin was isolated through a sonication‐assisted mild...

Comparison of kinetic and kinematic variables during single-leg jump landing between athletes with and without concurrent flexible flatfoot and genu varum deformities

Jumping and landing are among the most important movements in most sports; however, athletes with flexible flatfoot or genu varum deformities are vulnerable to lower limb injuries during these maneuvers. Therefore, this study aimed to compare the kinetics and kinematics of single...

Quaternary Ammonium Lignin Enabling High‐Na + ‐Conductivity Gel Electrolyte and NaF‐Rich SEI Toward High‐Safety Sodium Metal Batteries

ABSTRACT Sodium metal batteries (SMBs) using gel polymer electrolytes (GPEs) are considered promising candidates for low‐cost, high energy density, and high‐safety energy storage devices. However, a persistent challenge lies in simultaneously achieving high Na + conductivity of G...

gp3sequences: An Auditable and Reproducible Framework for Ordered Categorical Sequence Analysis in R

Ordered categorical sequence analysis is distributed across specialist methods and software, making preparation decisions, method settings, diagnostics, and provenance difficult to inspect consistently across an end-to-end workflow. This paper presents gp3sequences, an R framewor...

The impact of the COVID-19 pandemic on institutionalization and healthcare costs in memory clinic patients

Background The COVID-19 pandemic disrupted healthcare services and daily routines, which may have particularly affected individuals with cognitive impairment or dementia who rely on continuity of care. However, the impact of these disruptions on institutionalization and healthcar...

Microfocused ultrasound for facial and neck rejuvenation

Facial and neck skin laxity reflects age‑related changes in collagen fibers and deeper support structures. Growing patient demand for effective, non‑invasive tightening has driven interest in microfocused ultrasound (MFU) as a treatment modality. This study aims to evaluate the c...

Analysis of anomaly characteristics in mineralized segments using core drilling and geophysical logging

Reliable recognition of mineralized intervals from borehole logging data remains difficult because weak mineralization, thin layers, borehole disturbance, and lithological changes may produce similar curve responses. This study develops a multi-parameter coupled anomaly identific...

Reported practice patterns in the use of local antibiotics for fracture-related infection among SICOT respondents: an international survey

Abstract Background Local antibiotics are increasingly used in the management of fracture-related infection (FRI), but international practice patterns regarding their indications, antibiotic selection, and application methods remain heterogeneous and insufficiently standardised....

METHODS FOR ASSESSING THE STRESS-STRAIN STATE FOR PREDICTING THE SERVICE LIFE OF MODERN STRUCTURES MADE OF POLYMER COMPOSITE MATERIALS

This paper presents the results of shear test simulation and strength assessment of polymer matrix composites using the finite element method in comparison with experimental data.

Mitigating Long-Chain Fatty Acid Inhibition in Anaerobic Digestion of Model LCFA Substrates with Ruminococcus flavefaciens Bioaugmentation

Anaerobic digestion of high-lipid waste possesses substantial biomethanation potential. However, its stability is readily inhibited by the accumulation of long-chain fatty acids (LCFAs). In this study, pure stearic acid and oleic acid were employed as model LCFA substrates to sim...

Hydrothermal-Assisted Fabrication of Eco-Friendly ZnO/Tapioca Nanocomposite Films with Enhanced Structural and Optical Properties

The growing demand for environmentally sustainable materials has encouraged the development of biodegradable polymer nanocomposites with improved functional properties. In the present study, ZnO/tapioca starch nanocomposite films were fabricated by combining hydrothermally synthe...

FREUD AND JUNG - ALEXIS KARPOUZOS

The theory of archetypes is Jung's most original and philosophically ambitious contribution. Archetypes are not contents but forms — not specific images but the structural predispositions that determine what kinds of images the psyche tends to produce under what circumstances. Ju...

Indoor air ventilation and recommended capacity assessment at university facilities to reduce airborne risk spread of infectious agents

This study presents an in-situ methodology to assess indoor ventilation performance and estimate the recommended percentage of maximum occupancy (RPMO) for reducing airborne disease transmission risks. Using carbon dioxide (CO2) as a tracer gas, Air Changes per Hour (ACH) were de...

Latent profiles of AI teaching self-efficacy and their associations with occupational well-being among vocational education teachers in China: the moderating role of AI anxiety

The rapid diffusion of artificial intelligence (AI) tools has placed Chinese vocational education teachers at the frontline of a transition combining instructional, practical-training, and emotional demands. Although prior variable-centered research has linked teachers’ AI-relate...
