The bi-disciplinary technique was used to assess its hydrocarbon-oxidizing activity, namely: microbiological research was carried out in parallel with hydrochemical investigation of the natural water samples and samples enriched with diesel fuel. The Moldovan-Romanian transboundary section of the Prut River includes various ecological zones, such as the Costești-Stanca Reservoir, the mouth of the Jijia River, the Prut floodplains with the relict Beleu Lake (where oil extraction is carried out despite the fact that it is a protected area of the scientific reserve "Prutul de Jos") and the Prut River mouth with the Giurgiulesti International Free Port. The microbial community of fluvial bacterioplankton corresponds to the specific conditions of each these biotopes, being the most reproducible and adaptable component of the biota. The results obtained in the study of the Prut River bacterioplankton demonstrate the presence of hydrocarbon-adapted microorganisms with a good potential to utilize petroleum products in their metabolic processes.

The validation of the simulation code is obtained using the data of AAPM TG-195 report. Deposited energy amount as a function of increasing source energy is calculated over a wide energy range. The behavioral changes in X-ray absorption as well as transmission are examined using the F6 Tally Mesh extension of MCNPX code. Moreover, deposited energy amount is calculated for modeled body phantom in the same energy range.Results and discussionsThe diverse distribution of glands has a significant impact on the quantity of energy received by the various breast layers. In layers with a low glandular ratio, low-energy primary X-ray penetrability is highest. In response to an increase in energy, the absorption in layers with a low glandular ratio decreased. This results in the X-rays releasing their energy in the bottom layers. Additionally, the increase in energy increases the quantity of energy absorbed by the tissues around the breast.

Hence, the development of safe and effective new anti-antitubercular agents in addition to suitable nanocarrier systems has become of utmost importance and necessity. Our research aims to develop liposomal vesicles that contain newly synthesized compounds with antimycobacterial action. The compound being studied is a derivative of imidazo-tetrazine named 3-(3,5-dimethylpyrazole-1-yl)-6-(isopropylthio) imidazo [1,2-b] [1, 2, 4, 5] tetrazine (compound 1). Several factors that affect the liposomal characteristics were studied. The maximum encapsulation e ciency was 53.62 ± 0.09. The selected liposomal formulation T8* possessed mean particle size about 205.3 ± 3.94 nm with PDI 0.282, and zeta potential was + 36.37 ± 0.49 mv. The results of the in vitro release study indicated that the solubility of compound 1 was increased by its incorporation in liposomes. The free compound and liposomal preparation showed antimycobacterial activity against M. tuberculosis H 37 R v (ATCC 27294) at MIC value 0.94-1.88 µg/ml. We are predicting that the liposomes may be a good candidate for delivering of new antitubercular drugs.

The chemical compositions and glass densities are used in terms of determining some critical attenuation properties, such as linear and mass attenuation coefficients, half value layer, and effective atomic number values. Based on the rise in density, it was determined that the maximum concentration of WO 3 also resulted in a significant change in the overall gamma-ray absorption properties, when all of the study's findings were examined. It was observed that the glass sample, in which TeO 2 and WO 3 were 40 mol%, had the highest density. It was found that this glass with the highest density has the highest linear attenuation coefficient and mass attenuation coefficient and the lowest half value layer among the four samples specified. This demonstrates that WO 3 inclusion is a functional component that may be used in tellurium glasses and is a suitable material for situations requiring increased gamma-ray absorption properties.
