In this paper we study the integral curve in a random vector field perturbed by white noise. It is related to a stochastic transport-diffusion equation. Under s
The temperature curve in the solar chromosphere has puzzled astronomers for a long time.Referring to the structure of supergranular cells,we propose an in ducti
One new dammarane-type triterpene saponin, named (20S)-3β,20,21-trihydroxydammar-24-ene 3-O[α-L- rhamnopyranosyl-(1→2)][β-D-xylopyranosyl(l→3)]-β-D-glucop
The thermodynamic properties of the reaction of amide and formaldehyde were calculated via B3LYP method when substituents chosen included CH3, CH2CH3, CH2CH2CH3
This paper describes an experimental investigation on the flow characteristics within a rotating cylinder containing a rolling bed of sand.The axis of the cylin
Multi-Relaxation-Time Lattice Boltzmann Method (MRT LBM) is of better numerical stability and has attracted more and more research interests. The previous MRT L
A series of novel azasterols 8a―8h and 10a―10c were synthesized from the key intermediate 6 by acylation and deprotection. Compound 6 was obtained through a s
[Hmim]3PW12O40 was developed and used in the acetalization of carbonyl compounds in excellent yields. The ionic liquid-heteropoly acid hybrid compound and react
