Exploring the Potential of Posidonia oceanica Fibers in Eco-Friendly Composite Materials: A Review

The growing demand for sustainable materials has driven the exploration of natural fibers as eco-friendly alternatives to synthetic reinforcements for composites. This study investigates the potential of Posidonia oceanica, an abundant marine biomass, which is often driven to be stacked on the backshore and used so far for energy recovery and low-value applications, as a filler and possible reinforcement in cementitious and polymer composites. Most applications of Posidonia are concentrated in the...

Expression Analysis of Circulating miR-21, miR-34a and miR-122 and Redox Status Markers in Metabolic Dysfunction-Associated Steatotic Liver Disease Patients with and Without Type 2 Diabetes

Metabolic dysfunction-associated steatotic liver disease (MASLD), a hepatic form of metabolic syndrome, often co-occurs with type 2 diabetes (T2D) and now affects approximately 30% of the global population. MASLD encompasses conditions from simple steatosis to metabolic dysfunction-associated steatohepatitis, with oxidative stress (OS) driving progression through inflammation. This study analyzes the expression levels of circulating miRNAs and redox status markers in MASLD patients with and without...

A condition equivalent to the Hölder continuity of harmonic functions on unbounded Lipschitz domains

Our main result concerns the behavior of bounded harmonic functions on a domain in [Formula: see text] which may be represented as a strict epigraph of a Lipschitz function on [Formula: see text]. Generally speaking, the result says that the Hölder continuity of a harmonic function on such a domain is equivalent to the uniform Hölder continuity along the straight lines determined by the vector [Formula: see text], where [Formula: see text] is the base of standard vectors in [Formula: see text]....

Water mite diversity from southwestern Türkiye through the lens of the DNA barcodes, with the description of one new species (Acari, Hydrachnidia)

This study presents the molecular and morphological results from an analysis of water mites collected in southwestern Türkiye. 83 COI barcodes are provided, clustered into 40 BINs, with 23 BINs being unique and deposited for the first time in the Barcode of Life Data Systems (BOLD). The first DNA barcodes for eight water mite species are uploaded into the BOLD database. In total, 34 water mite species were identified and one of them, Iranothyas marismortui (Gerecke, 1999) is newly reported from...

Uncoupling of General Linear Multi-degree-of-freedom Structural and Mechanical Systems Through Quasi-diagonalization

Abstract This paper develops a fundamental result in linear algebra by providing the necessary and sufficient conditions for the simultaneous quasi-diagonalization of two symmetric matrices and two skew-symmetric matrices by a real orthogonal congruence. This result is used to study the uncoupling of general linear multi-degree-of-freedom (MDOF) structural and mechanical systems described by arbitrary damping and stiffness matrices through quasi-diagonalization, and real orthogonal...

Phenolic Content and Antioxidant Potential of Wine Extracts

Background/Objective: Phenolic compounds are considered to be the most important parameters of wine quality, contributing not only to its organoleptic characteristics, but to various health benefits associated with wine consumption. Although these are successfully extracted from grapes and winemaking by-products, there is no data on extraction from wine itself. This is particularly interesting in light of the fact that the variability of wine polyphenols is not only attributed...

Use of Eye-Tracking Technology to Determine Differences Between Perceptual and Actual Navigational Performance

This study uses eye-tracking technology (ETT) to investigate discrepancies between seafarers’ perceived and actual performance during simulated maritime operations. The primary objective is to explore how misperceptions regarding the use of navigational tools—such as visual observation, radar, and ECDIS—may contribute to discrepancies in situational awareness, which is critical for safe navigation. By comparing participants’ self-reported perceptions with objective data recorded by ETT, the study...

The Montenegrin 2022 Report Card on Physical Activity for Children and Youth

Background: The main purpose of this study was to summarize the results of the Montenegrin 2022 Report Card on physical activity (PA) for children and youth, which is used to identify and grade PA to help optimize the current situation and provide an improved basis for the creation of a future monitoring system. Methods: Following the methodology established by the Active Healthy Kids Global Alliance, the Montenegrin team conducted an assessment of PA of Montenegrin children and youth through 12...
