Synthesis and biodegradation testing of some synthetic oils based on ester

Synthesis and biodegradation testing of some synthetic oils based on ester

There is an urgent need to develop pollution-free and environmentally friendly lubricants as an alternative to mineral-based lubricants17. Rape, soybean, and palm oils are among examples of basic oils. They possess good tribological properties. Despite their obvious benefits, they have limited corrosion resistance and are in danger of hydrolytic and oxidative instability18. Esters of glycols …

Circulating myeloid-derived MMP8 in stress susceptibility and depression

Circulating myeloid-derived MMP8 in stress susceptibility and depression

Mice The following mouse strains were used: For standard CSDS experiments, 7-week-old C57BL/6 J (stock no. 000664) mice were purchased from The Jackson Laboratory. For bone marrow transplantation experiments, 4 week-old B6.SJL-Ptprca Pepcb/BoyJ (stock no. 002014, B6 CD45.1) mice were obtained from The Jackson Laboratory. B6.129(Cg)-Ccr2tm2.1Ifc/J (stock no. 017586, Ccr2rfp) and B6.129×1-Mmp8tm1Otin/J (stock no. 005514, Mmp8−/−) …

Insights into the DHQ-BN: mechanical, electronic, and optical properties

Insights into the DHQ-BN: mechanical, electronic, and optical properties

We begin by analyzing the optimized lattice arrangement of DHQ-BN, as illustrated in Fig. 1. Geometry optimization calculations, performed with the PBE and HSE06 methods, produce comparable lattice parameters. However, for the sake of this discussion, we focus on the results obtained using the HSE06 method, which is highlighted in Fig. 1 and summarized in …

Preparation and characterization of high-performance ceramic proppant from recycling utilization of oil-based drilling cuttings pyrolysis residues

Preparation and characterization of high-performance ceramic proppant from recycling utilization of oil-based drilling cuttings pyrolysis residues

The influence of sintering temperature and ODCPRs contents on the performance of the proppants Performance test To determine the effect of sintering temperature and ODCPRs contents on the physical–mechanical performance of proppants and optimize the sintering conditions, proppants were prepared with various ratios of ODCPRs and sintered at different temperatures. The physical and mechanical performances …

Global surveillance of antimicrobial resistance in food animals using priority drugs maps

Global surveillance of antimicrobial resistance in food animals using priority drugs maps

This analysis is structured in five steps (Fig. 5a–e): (a) collection and extraction of epidemiological information from point prevalence surveys (PPS); (b) mapping distribution of resistance prevalence using three machine learning models; (c) ensembling predictions using Gaussian process stacked generalization; (d) mapping priority antimicrobials for surveillance; and (e) estimating prediction uncertainty of maps generated in steps …

Microstructural brain abnormalities, fatigue, and cognitive dysfunction after mild COVID-19

Microstructural brain abnormalities, fatigue, and cognitive dysfunction after mild COVID-19

We evaluated a group of 97 unvaccinated individuals (without history or current presence of symptoms of anxiety, depression and psychiatric symptoms) after a mild infection with SARS-CoV-2. We detected persistent headache, fatigue, excessive somnolence, cognitive dysfunction, and subtle microstructural white MRI abnormalities. Although the DTI analysis revealed an increase in axial diffusivity compared to controls, …
