Culture and entrepreneurship are complex and interrelated social concepts. The paper aims to determine the importance of national culture for entrepreneurship progress in the Eastern Partnership (EaP) region. The article focuses on a meta-analysis of the inputs integrated into a European Union Policy Index. It aimed to underline the nature of specific interrelation mechanisms of the cultural dimensions that could contribute to developing a performant entrepreneurial environment. The correlation analysis used in the paper detects the most ”sensitive” pairs of variables related to national culture and entrepreneurship activities. Results show a highly significant relationship between the Motivation Towards Achievement and Success index and a large part of the dimensions of the sustainable entrepreneurial development of EaP countries, especially Internationalization and Support Services for Small and Medium Enterprises SMEs and start-ups. Another significant relationship is between Individualism and the Development of Entrepreneurial Activities in the analyzed countries.

The presence of particulate matter,along with other specific air pollutants, significantly contributes to the degradation of air quality outdoors and indoors.High concentrations of PM in indoor educational spaces influence students health and daily performance.This study presents the results of daily monitoring of PM1, PM2.5,and PM10 concentrations carried out between May 9 and May 15, 2024, at 8:00, 10:00, 12:00, 14:00,and 16:00 in various indoor environments of the M University Complex at "Aurel Vlaicu" University of Arad, including two corridors, two student laboratories,and an auditorium, as well as in the outdoor environment. For indoor environment, the findings indicated relatively low levels of particulate matter, suggesting goodair quality for student health with average PM1 concentrations ranged from 2 µg/m³ to 6 µg/m³, PM2.5 from 4 µg/m³ to 11 µg/m³, and PM10 from 5 µg/m³to 14 µg/m³.

The present paper describes the synthesis and characterization of a new ditopic proligand with two terpiridines linked bya diselenide unit, obtained by a Steglich esterification procedure between a biscarboxylic acid functionalized with a diselenide unit and 4-([2,2:6,2'-terpyridin]-4-yl)phenol. The compound was characterized by FT-IR, NMR (1D and 2D) and UV-Vis spectroscopiesandESI-MS analysis.Moreover, the photophysical properties of the ditopic ligand were investigated in freshly prepared dichloromethane solution.The compoundwas found to be emissive with a maximum centered at 354 nm.

The main objective of the present study was to perform a general screening of surface water quality in Jiu Valley mining rea. Surface waters were collected from West Jiu river and some of its tributaries (Capri?oara creek; Baleia creek; Barbateni creek; Vacii Valley creek; Tusu creek; Bulzu creek) to analyze several general physico-chemical and some specific chemical quality parameters. The general physico-chemical parameters: pH, redox potential (ORP), salinity, total dissolved solids (TDS), electrical conductivity (EC) and dissolved ions were analyzed.The analyzed water samples had a neutral pH, with a relatively low content of dissolved salts, except for Capri?oara creek. Based on their dissolved ions content, most of the analysed waters correspond to Istquality class, which reflect a very good ecological status.Because of the high content of sulphate, calcium and magnesium, water sampled from Capri?oara creek corresponds to Vthclass (based on SO42-content), IVthclass (Ca2+level) and IIIrd(Mg2+concen-tration) class, indicating a bad / low / moderate ecological status. The water quality degradation of Capri?oara creek in the investigated area may be associated with several anthropic activities identified in the area, but to confirm this sourcesfurther investigations are needed.

Hedera helix is an evergreen perennial vine plant often pruned for ornamental or ecological purposes. This process generates a significant amount of biomass waste. Therefore, this study aimed to use this biomass to obtain extracts rich in phenolic compounds and as a mediator for the biosynthesis of gold nanoparticles (AuNPs). Biochemical assays (DPPH, FRAP, Folin–Ciocalteu, and colorimetric determination of total flavonoid content) revealed that the extracts have significant radical scavenging activity and moderate phenolic and flavonoid compound levels. These findings were further supported by UHPLC analysis, providing insight into the chemical composition of these extracts. Only the most efficient extract (water infusion) was further used for AuNPs synthesis in three different synthesis medium concentrations of HAuCl4 (0.5, 1, and 2 mM). Visual and UV-Vis spectroscopy analyses revealed the successful formation of AuNPs, while SEM-EDS analysis confirmed the morphology (spherical and polydisperse nanoparticles) and elemental composition. The antimicrobial activity was evaluated through the broth microdilution method against five microbial strains (Staphylococcus aureus, Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa, and Candida albicans) and two antibiotics (penicillin and gentamicin). The resulting bacterial inhibition rate (BIR%) revealed a low inhibitory activity for AuNPs, significantly lower than for the tested antibiotics. It suggests that further AuNPs functionalizations may be required to increase their biological activity.

Luminescent liquid crystalline metal complexes are attractive multifunctional materials due to their great potential of applicability in a wide range of domains from technological to medical fields. This review is focused on the luminescent homo– and hetero–polymetallic metallomesogens containing d-block metal ions and different mono and polydentate ligands published in the last ten years highlighting their ability to self-assembly in ordered lamellar or columnar phases according to their molecular structure. The luminescent properties in solution, solid and liquid crystalline states are also discussed.
