Another exact solution for two-dimensional, inviscid sinh Poisson vortex arrays

Arrays of vortices are considered for two-dimensional, inviscid flows when the functional relationship between the stream function and the vorticity is a hyperbolic sine. An exact solution as a doubly periodic array of vortices is expressed in terms of the Jacobi elliptic functions. There is a threshold value of the period parameter such that a transition from globally smooth distributions of vorticity to singular distributions occurs. © 2003 American Institute of Physics.published_or_final_versio

Identification of the major chemical constituents and their metabolites in rat plasma and various organs after oral administration of effective Erxian Decoction (EXD) fraction by liquid chromatography-mass spectrometry

A simple and specific LC-DAD-ESI-MS/MS method has been developed and applied for the primary investigation of the chemical constituents absorbed or metabolized in vivo, after the rat oral administration of Erxian Decoction (EXD), a Chinese medicine prescription for menopausal syndromes. Through the online ESI-MS n analysis, a total of 35 compounds have been identified or tentatively characterized from the seven tested samples, and 13 of them were unambiguously identified through a direct comparison of the retention time, UV spectra and MS n fragmentation patterns with the authentic ones. The results showed that 21 compounds were detected from rat plasma, 20 compounds were detected from rat kidneys and adrenal glands, 19 compounds were detected from rat ovaries, 12 compounds were found in rat intestines, nine compounds were identified from rat livers and nine compounds were detected from rat brains at certain time points after oral administration of the eff ective EXD fraction.
