This paper deals with a new analytical model for microfluidic passive mixers.Two common approaches already exist for such a purpose.On the one hand, the resolution of the advection-diffusion-reaction equation (ADRE) is the first one and the closest to physics.However, ADRE is a partial differential equation that requires finite element simulations.
In this paper, a patch antenna is proposed with reconfigurable patterns in the azimuth plane.The basic Pizza Screens structure of the antenna is a circular patch upon which a vertical slot is etched.In addition, a row of shorting posts along the horizontal direction is placed underneath the patch.With the aid of characteristic mode analysis (CMA),
Aim: The study investigated the effect of using surface protection agents in the adaptation of external and internal margins of restorations subjected to simulated erosion.Methods: Cavities with margins in dentin were prepared in bovine incisors (n=120).Adhesive restorations were placed using a three-step etch&rinse adhesive system and nanofilled c
Energy router is an emerging device based on power electronic technology, which can realize the flexible distribution of electric energy in the power system.Therefore, the use of energy routers to improve the operating conditions of the power system not only has broad development prospects, but also brings economic benefits.In this regard, this pap
