In this paper, a kinetic Boltzmann model equation involving internal degrees of freedom is constructed for thermodynamic non-equilibrium polyatomic gases, in which the continuous distribution mode rotational energy and discrete quantum effect vibrational are both considered, respectively. By theoretically analyzing “recurrence feature” model, it found that root comes from translational-rotation...

We write to raise some of a number of serious concerns about the recent paper ‘Single maintenance and reliever therapy (SMART) of asthma: a critical appraisal’. We believe that it is written in a misleading fashion and contains important errors of fact, presentation and inference. Tabulated data for symptoms, reliever use and exacerbations are presented only for patients randomly assigned to SM...

ROSENAO [R] has recently proposed a regularized version of the ChapmanEnskog expansion of hydrodynamics. This regularized expansion resembles the usual Navier-Stokes viscosity terms at low wave numbers, but unlike the latter, it has the advantage of being a bounded macroscopic approximation to the linearized collision operator. In this paper we study the behavior of the Rosenau regularization o...
