Sintered stainless steel (SSS) microfiltration membranes, which served as electrode directly, were used for the experiment of separating Alamin, a calcium salt and protein containing particles, found in dairy processing. Fouling and cleaning of the SSS membranes under the application of an external electric field were studied. The imposed electric field was found, diverging the pH of permeate a...

Free-run juice (“saignée”) from Pinot Noir must was filtered by nanofiltration (NF) and then, with the aim of promoting diffusion anthocyanins, retentate fraction returned to tank immediately permeate at different densities during alcoholic fermentation. This extraction strategy compared thermovinification (TV). The results obtained demonstrate that NF shows promise as an alternative non-therma...

Generalized frames are an extension of frames in Hilbert  spaces and  Hilbert $C^*$-modules. In this paper, the concept ''Similar" for modular $g$-frames is introduced and all of operator duals (ordinary duals) of similar $g$-frames with respect to each other are characterized. Also, an operator dual of a given $g$-frame is studied where $g$-frame is constructed by a primary $g$-frame and an or...
