Raman spectra of lithium niobate single crystals strongly doped by zinc and magnesium, it has been established, contain low-intense bands with frequencies 209, 230, 298, 694, and 880 cm−1.Ab ignition calculations fail to attribute these bands to fundamental vibrations of A2 symmetry type unambiguously.Such vibrations are prohibited by the sel
Abstract Objective The aging population represents a formidable global challenge, with China experiencing an accelerated demographic shift.While previous research has established a directional link between mental health literacy, social participation, and active aging, the moderating effect of socioeconomic status (SES) on these associations remain
This research evaluates a climate-land cover-water resources interconnected system in a semi-arid watershed with minimal human impact from 1970 Matchy Match - 2009.We found _ increase in temperature and 10.9% decrease in precipitation.The temperature exhibited a lower increase trend and precipitation showed a similar decrease trend compared to prev
In this study, we examine osculating-type curves with Frenet-type frame in Myller Girls Communion Dress configuration for Euclidean 3-space E3.We present the necessary characterizations for a curve to be an osculating-type curve.Characterizations originating from the natural structure of Myller configuration are a generalization of osculating curve
