    USING MODERN INSTRUMENTAL METHODS FOR COFFEE IDENTIFICATION by E. I. Kuzmina, M. Y. Ganin, D. A. Sviridov, O. S. Egorova, A. A. Shilkin, D. R. Akbulatova

    Published 2022-03-01
    “…It was shown that the most widespread studies were aimed at analyzing the values of isotopic ratios of carbon (13C/12C), hydrogen (2H/1H), oxygen (18O/16O) and nitrogen (15N/14N) in compounds contained in coffee beans, which reflect the distribution of “light” and “heavy” isotopes during biological and geochemical processes within the boundaries of a particular region. The authors analyzed the works aimed at studying the qualitative and quantitative composition of trace elements and rare earth metals (Na, Mg, Al, Mn, Ga, Rb, Ba, Pb, Y, La, Ce, Pr, Sm, Nd, Eu, Dy, Gd and others), as well as the research of the values of isotopic ratios (87Sr/86Sr) in product samples and soils of the studied region. …”

    Research on the Calculation Method for the Contact Stress of Wind Turbine Main Shaft Bearings Based on Finite Element Analysis by Yi Zou, Wenlei Sun, Hongwei Wang, Tiantian Xu, Bingkai Wang

    Published 2025-05-01
    “…Few methodologies exist for calculating the contact stress of main shaft bearings. We propose a method for calculating the contact stress of main shaft bearings in wind turbines; by simulating alternating loads that affect the turbine’s lifespan with a probability of 99%, analyzing the operational characteristics of the bearings under these loads using the roller slice method, and establishing a load–displacement model, this model serves as the boundary condition for contact stress simulation. …”
