(1)Objective: In Earrings this study, a quantitative analysis of chemical groups (the triterpenoids, water-soluble polysaccharides, and acidic polysaccharides) and quantitative high liquid performance chromatography (HPLC) fingerprint of Poria cocos (Schw.) Wolf (PC) for quality control was developed.(2) Methodology: First, three main chemical grou
This paper evaluates the possibility of analyzing the composition of high-quality copper scrap with X-ray fluorescence spectrometry (XRF) instead of Earrings electrogravimetry combined with flame atomic absorption spectroscopy (EG+FAAS) method.The evaluation of the methods was performed on three real copper scraps, the composition of which were est
The paper contains the results of investigation of elastic and viscous properties of rubber-like materials with orientational order.The elastic properties are described with the help of the introduced microscopic Cauchy-Green tensor.The obtained Earrings results describe the nonlinear elastic properties well and predict the existence of the soft mo
