    Influence of Bilateral Upper Limb Morphological Asymmetry on Grip Strength Related to Gender in Non-Athlete University Students
    (MDPI, 2026-01-08) Alecu Stefan; Onea Gheorghe Adrian; Badau Dana; Badau Adela; Nechita Florentina
    Bilateral morphological asymmetry of the upper limbs may influence grip strength even in semi-active young adults. Understanding this relationship is important for identifying early neuromuscular imbalances with implications for ergonomics and rehabilitation. This study aimed to examine associations between upper limb anthropometric characteristics and grip strength in non-athlete students, considering gender and manual dominance. The sample included 192 healthy university students (110 females, 82 males; mean age 19.92 ± 1.4 years) without prior sports training. Thirteen bilateral anthropometric parameters of the upper limbs were assessed, including hand and palm dimensions, segmental lengths, and arm and forearm circumferences, along with grip strength measured by dynamometry in two positions: arm extended and arm flexed at 90◦ . Statistical analysis revealed significant differences in forearm length, arm and forearm circumferences, and grip strength (p < 0.001). The dominant limb consistently demonstrated higher grip strength, with mean differences of approximately 2 kg. Male participants showed higher absolute values for all morphological and functional variables, whereas stronger correlations between distal upper-limb morphology and grip strength were observed in females. These findings indicate that, despite largely symmetric skeletal dimensions, moderate functional asymmetries exist and grip strength is influenced primarily by local muscular development rather than overall limb size

    This diploma project aims to investigate the available platforms for digital archiving, including open-source solutions, and the implementation of such a solution at Transilvania University of Brașov. The initiative is aligned both with national plans for the development of digital infrastructure for open science - in particular through the participation of the university in the National Open Science Cloud Initiative (EN-NOSCI) - and with European guidelines for promoting transparency in research in South-East Europe, reflected in the NI4OS-Europe project. At the national level, there is a lack of a coherent policy for the promotion and adoption of open access practices to research results, which contributes to their marginal presence in the public space. Facilitating open access to scientific information could have a significant impact on the academic community and civil society, stimulating inter-institutional cooperation and strengthening the dissemination of knowledge to citizens.

    Current Research on MoS2-Based Heterojunction Photocatalysts for Persistent Organic Pollutants Degradation
    (MDPI, 2025-12-10) Isac Luminita; Cazan Cristina
    Currently, continuous population growth and unsustainable industrialization have caused ongoing water pollution, with harmful consequences for human health and the environment. Persistent organic pollutants (dyes, active pharmaceutical compounds, pesticides, etc.) are discharged into water from various industrial, agricultural, and domestic activities. Therefore, wastewater treatment through sustainable technologies is imperative, representing a great and real challenge for worldwide research. Photocatalysis, an innovative and green technology, uses advanced oxidation processes in the presence of a photocatalyst, usually a semiconductor with expanded light absorption ability and high conductivity for photogenerated charge carriers. Molybdenum disulfide (MoS2) is an n-type semiconductor with different morphologies, variable bandgap energies (Eg = 1.1-2.63 eV), and numerous applications. Although pristine MoS2 exhibits special structural and optoelectronic properties, its photocatalytic activity can be further improved through various strategies, and constructions with the heterojunctions construction with other semiconductors being frequently pursued. This review extensively studies the recent research (the last 4 years) on MoS2 and MoS2-based heterojunction (I-type, II-type, Z-scheme, S-scheme) photocatalysts for degrading organic contaminants under simulated and sunlight irradiation in wastewater treatment. Even if in a relatively short time (a few years) valuable studies have been reported on this topic, there are still numerous challenges facing future research.
