Geotechnical Problems on Madeira Island: Slope Protection in Central Funchal—A Case Study

Volcanic islands are highly exposed to interacting geotechnical and hydrogeomorphological hazards, particularly where steep relief, intense rainfall, fractured volcanic rocks, and urban development coincide. This study analyzes the slope located along Avenida Sá Carneiro in centr...

Microbiota-Associated Metabolites as Biomarkers and Therapeutic Opportunities in Inflammatory Bowel Disease

Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, are chronic inflammatory conditions of the gastrointestinal tract characterized by periods of active disease and remission. Their pathogenesis is multifactorial and involves genetic predisposition, immun...

The Impact of Test Conditions and Lay-Up Configuration on SEA in Carbon–Epoxy Tubes

This article presents the effect of test velocity and the percentage of unidirectional (UD) and woven (WF) fibers on specific energy absorption (SEA). Composite tubes with an internal diameter of 20 mm were fabricated using five prepreg layers. Progressive crushing of the specime...

Functional Variability and Interchangeability of Commercial Limestone Powders in Concrete: An Experimental and Multivariate Screening Approach

Commercial limestone powders marketed under the same general material designation may differ in composition and particle characteristics, raising questions about their functional interchangeability in concrete. This study combined experimental concrete testing with multivariate d...

Waste-Derived Biochar for Sustainable Wastewater Treatment and Resource Recovery: A Review from the Circular Economy Perspective

The growing generation of organic waste and the increasing demand for sustainable wastewater treatment have stimulated interest in waste-derived biochar as a multifunctional material for pollutant removal and resource recovery. This review critically evaluates the relationships b...

Influence of Bond Coat Roughness on the Microstructure and Mechanical Properties of EB-PVD TBCs

The surface condition of the bond coat is an important factor governing the growth and microstructural development of electron-beam physical vapour deposition (EB-PVD) TBCs. In this study, 7 wt.% yttria-stabilised zirconia (7YSZ) coatings were deposited by EB-PVD on vapour-phase...

Spectroscopic Evidence of Free Radicals Generated by Indocyanine Green Under Light Irradiation

Reactive oxygen species (ROS), particularly free radicals involved in type I photodynamic mechanisms, are key mediators of photodynamic therapy. Indocyanine green (ICG), a clinically approved near-infrared dye, is increasingly being considered as a photosensitizer. It has attract...

Research on the Self-Heating Effect in Resistance Temperature Sensors for Flow Measurements

This article introduces an experimental approach to evaluating the thermal resistance of industrial resistance temperature sensors and demonstrates their use for estimating the flow rate of the surrounding medium. A new method, the Self-Heating Effect Anemometry (SHEA) method, is...

Effect of adding titanium on corrosion and wear resistance of Al0.7CoCrFeNiTix high entropy alloy

Abstract High-entropy alloys based on the Al-Co-Cr-Fe-Ni system are considered promising materials for applications exposed to wear and corrosive environments. In this study, the effect of titanium addition on the microstructure, mechanical properties, tribological performance an...

Image Quality Assessment Methods for Multispectral Pan-Sharpening Images: A Comprehensive Review

Multispectral pan-sharpening aims to fuse high-resolution panchromatic and low-resolution multispectral imagery. However, this process introduces spatial artifacts and spectral distortions. Assessing the quality of fused images remains a fundamental challenge due to the absence o...

Morphological, metabolic, and chemical changes in Candida albicans cells induced by the NaQSA complex

This study examines the effects of the sodium complex of quercetin-5′-sulfonic acid (NaQSA) on Candida albicans yeast cells. Flow cytometric analysis showed a concentration-dependent decrease in viable cell numbers after incubation with NaQSA, indicating reduced cellular viabilit...

Executable Threshold–Temporal Rules over Clinical Time Series: scoping review protocol v1.0

Protocol for a scoping review of executable threshold–temporal rules over clinical time series: rules that contain both a numerical threshold and a temporal operator, applied to sequences of clinical or physiological observations. The review charts four questions: (RQ1) which for...

A Technology Selection Support Model in Industry 4.0 for Quality Assurance and Traceability in the Production of Waste-Derived Functional Materials

The circular economy increases the importance of quality and traceability in functional materials produced from industrial, municipal, and agricultural waste. However, the selection of Industry 4.0 (I4.0) technologies in waste valorization remains unsystematic and weakly linked t...
