Sanggenon X, an unusual tri-O-bridged Diels-Alder adduct, was isolated from Cortex Mori Radicis.Its structure was established by spectroscopic analysis, including NMR and HR-MS (High Resolution Mass Spectrometry).Sanggenon X contained three O-bridged rings, where the oxygenated bridgeheads were CINNAMON EXTRACT all quaternary carbons.Chemical methy
Saurophaganax maximus is the designation of a massive theropod dinosaur recovered from the Kenton Member of the Upper Jurassic Morrison Formation in Oklahoma.The theropod was originally given the name Saurophagus maximus but was later revised to Saurophaganax maximus as the former did not conform to ICZN standards.Several autapomorphies were descri
two methods of formalist or Aristotelian and the realistic interpretation stem from different law theories.In the former method of interpretation, the interpreter, with the character of a mathematician, interprets in a mathematical way and draws conclusions from the previous rules.In fact, Matching Shirts in this method, the former rules are the sa
The stress path characteristics of surrounding rock in the formation of gob were analyzed and the unloading was solved.Taking Chengchao Iron Mine as the engineering background, the model for analyzing the instability of deep gob was established based on the mechanism of stress relief in deep mining.The energy evolution law was analyzed by introduci
