Medicinal plants containing essential bioactive ingredients are used to cure disease or disorder since time immortal. One of the aims of medicinal plant research is the isolation and identification of markers/ bioactive compounds. Isolation of the markers compounds and bioactive plant constituents has always been a challenging task for the researchers. Separation of these components from the me...

The phenomenon of centrifugal separation in a rotating multispecies plasma column is discussed. Rate equations for collisional separation are derived. Two electrostatic instabilities that are driven by centrifugal effects are also considered: a diocotron mode and a drift wave.

Leonardo Baldassarre is currently the Engineering Manager & Principal Engineer for Compressors & Expanders with General Electric Oil & Gas Company, in Florence, Italy. He is responsible for all requisition, and standardization as well as for detailed design of new products for centrifugal compressors, reciprocating compressors and turboexpanders. Dr.Baldassarre began his career with General Ele...

The accelerating fields (e. g. centrifugal acceleration and constant acceleration) can change the physical performance of nano-sensors significantly. Herein, a new size-dependent model is developed to investigate the scale-dependent dynamic behavior of nanowire-fabricated sensor operated in an accelerating field. The scale-dependent equation of motion is developed by employing a consolidation o...

The unusual infrared emission patterns of CH$^+$, recently detected in the planetary nebula NGC 7027, are examined theoretically with high-accuracy rovibrational wavefunctions and $ab$ $initio$ dipole moment curves. calculated transition moments quantitatively reproduce observed $J$-dependent intensity variation, which is ascribed to underlying centrifugal distortion-induced interference effect...

The numerical results of mathematical modeling a two-phase, axisymmetric swirling turbulent flow in the separation zone centrifugal separator are presented. movement carrier gas was modeled using RANS, which were closed SARC turbulence models, SST-RC model, and SSG/LRR-RSM-w2012 model. For solution problem, SIMPLE algorithm used. article compares calculation models. comparison calculations with...

The co-rotating mechanism is utilized for scroll vacuum pump application by one of the authors. It was found that the corotating scroll compressor is transformed to a centrifugal compressor by reducing the eccentricity between the two scrolls to zero. The authors propose a co-rotating scroll compressor which works not only as a positive displacement compressor, but also as a centrifugal one in ...
