Graphycal Abstract: This study assessed water quality in Cișmea, Orhei district (coordinates 47°24’56.0"N 28°45’05.9"E). Surface and underground water were analyzed for pH, conductivity, hardness, chloride, sulfate, and chemical elements. The concentration values of the 36 elements determined by the ICP-OES method are presented. Conductivity and sulfate deviations indicated high dissolved solids. Results revealed significant deviations from permissible levels: As (1.7-1.9x), Cd (3.4-3.5x), Pb (1.2-2.3x), Na (1.2-4.0x), and B (1.6-3.3x). Notably, Ba, Tl, and Bi concentrations were also detected.

https://doi.org/10.19261/cjm.2024.1234
Graphycal Abstract: This study investigates the radionuclide emissions from nuclear power plants (NPPs), focusing on the gas-aerosol emissions from reactors such as VVER-440. The radionuclide composition of these emissions is analyzed to determine the biological hazards they pose, particularly focusing on isotopes such as tritium and radiocarbon. The research highlights the patterns of radionuclide accumulation in fuel assemblies using "rank-size" coordinates, which provide a more visual and informative method compared to traditional atomic weight dependency analyses.

β-enaminoester; X-ray diffraction, monoclinic space, Hirshfeld surface, ADMET-Tox.
https://doi.org/10.19261/cjm.2024.1220
Graphycal Abstract: The compound 3-(2,4,6-timethyl-phenylamino)-but-2-enoate was obtained by the condensation reaction of ethyl acetoacetate and 2,4,6-trimethyl-phenylamine. X-ray structural analysis identified the structure of the synthesized β-enaminoester, NMR spectroscopy complemented it, and the structure stabilised by intramolecular interactions. The intermolecular contacts were further analysed by the mapping of contacts descriptors dnorm, de, di, the shape-by-shape index and surface property by electrostatic potential mapped on the Hirshfeld surface (HS). Global reactivity factors such as electronegativity, chemical hardness, potential, and softness were calculated using density functional theory. The effects of the molecular environment were accessed by analysing the electrostatic potentials surface mapped over the HS and the 3D-topology of energy frameworks. As a potential bioactive molecule, the physicochemical and ADME-Tox predictions were performed suggesting that title compound could be considered a promising drug candidate.

Graphycal Abstract: Apples of the Coredana, Golden Rezistent, Reglindis and Rewena varieties were studied. The quantitative and qualitative determination of organic acids and carbohydrates were using HPLC and CE methods. Determination of AA and TPC content was evaluated by spectrophotometric methods. The highest amount of organic acids was obtained in the 45th DAFB of harvest, the predominant being malic acid (15.09-21.64 g/100gDW). Sugars had the highest value in 97th DAFB, fructose being the main one (67.79-75.73 g/L). TPC and AA showed maximum values at the beginning of fruit harvesting, having 916.67-1316.13 mgGAE/100gDW and 16.94-23.51 mgAAE/100gDW, respectively. Unripe apples represent a natural source of organic acids and carbohydrates, significant amounts of polyphenolic compounds with antioxidant properties.

Graphycal Abstract: The current study aims to maximize the recovery of antioxidant phenolics from Algerian Trifolium tomentosum L. using an innovative green process: ultrasonic assisted extraction (UAE). Using response surface methodology (RSM), the optimal UAE parameters for maximum responses (total phenolic content, total flavonoid content, and total antioxidant capacity) were 70% ethanol concentration, 30.4545 minutes of extraction time, and 75°C extraction temperature.

Graphycal Abstract: The essential oil of Marrubium deserti from Bechar (Algeria) was investigated to determine its chemical composition, physico-chemical characteristics,the antibacterial and antifungal activities. The findings showed that α-phellandrene (25.05%), β-pinene (14.05%), and α-pinene (12.83%) were the major compounds of this oil. Moreover, it was displayed that the studied essential oil has good antibacterial power as well as a strong inhibitory effect on spore sporulation, germination, and pathogen fungus development.
