The initial-boundary value problem of the propagation of nonlinear longitudinal elastic waves in an initially strained rod is considered. The rod is assumed to
8-Hydroxyquinoline-5-sulfonic acid,covalently bound to filter cellulose,was used for preconcentrating trace rare earth element(REE) ions from complex matrices a
The nature of the model that produced Enso-like oscillation is further discussed. There are some independent parameters in almost all simple models. The nature
Tetrahydrofuran ring can be opened with acyl chlorides or anhydrides catalyzed by gallium triiodides to afford iodo esters under mild conditions in good yields.
In order to study motional properties of pulsatile blood flow in axially moving arteries, the authors derived some expressions of the pulsatile blood flow from
It is proved that if f is a Teichmüller self-mapping of the unit disk with a holomorphic quadratic differential φ1, and φ satisfies the growth condition m(φ
