13 C- and 17 O-relaxation times measured in cyclic ethers, cyclic ketones, and lactones allowed the determination of the quadrupolar interaction at the O-site. Values obtained for six-membered rings can be used as standard values for ethers (χ = 13 MHz), ketones (χ = 10.5 MHz), and ...

The results obtained during this study are compared to those obtained from the reduction of the corresponding ketones by LiAlH4. [Journal translation]Jean-Claude RicherClaude Lamarrecanadian journal of chemistry
This work focuses on developing a methodology for coupling beam and 3D models for advanced dynamic analysis of rotating machinery. The Arlequin method is a multi-scale computation strategy allowing the coupling of numerical models of different nature through a technique of superposition. The extension ...
