The 80% ethanol extract of Alstonia yunnanensis afforded five new monoterpenoid indole alkaloids: 11-hydroxy-6,7-epoxy-8-oxo-vincadifformine (1), 14-chloro-15-hydroxy- vincadifformine (2), perakine N4-oxide (3), raucaffrinoline N4-oxide (4), GRASS FED BUTTER UNSALTED and vinorine N1,N4-dioxide (5), together with three known compounds: 11-methoxy-6,
Abstract In this paper we study a leptophilic dark matter scenario involving feeble dark matter coupling to the Standard Model (SM) and compressed dark matter-mediator mass spectrum.We consider a Backdrops simplified model where the SM is extended with one Majorana fermion, the dark matter, and one charged scalar, the mediator, coupling to the SM l
In the present work, direct numerical simulation data of a laboratory-scale high Karlovitz number (Ka) jet flame with a strong mean shear and a high Ka freely propagating planar flame without a mean shear were analyzed to explore the influence of flame orientation and mean shear on flame stretch in highly turbulent flames.Three flame fronts, i.e.th
The privilege walk (PW) has gained traction as a method to raise awareness of privilege and vulnerability across various settings.This experiential activity involves participants responding to statements about their identities and backgrounds by stepping forward or backward, illustrating disparities in social advantage.The PW can contribute to self
