There are several ways of computing a relevant approximation of this function, using for example technique originating from the approximation of Hamilton Jacobi problems, or the fast sweeping method.

But the usual Maxwell models allow one to define well motions mostly for one-dimensional flows only. To define unequivocal multi-dimensional viscoelastic flows (as solutions to well-posed initial-value problems) we advocated in [ESAIM:M2AN 55 (2021), p. 807-831] an upper-convected Maxwell model for compressible flows with a symmetric-hyperbolic formulation.

To obtain high quality final products, biomolecules can be exposed in production lines to stress factors such as heating, stirring and multiple surfaces contact before their commercialization. These factors can induce stability and e ffi cacy loss. In this work, the antibacterial activity of lysozyme (LSZ),aproteinusedasantibioticwhichactsbydisruptingthebacterialcellwall,wasstudiedaftertwo operations: heating and ultrafiltration. Antibacterial activity after extreme stress factors is expected to decrease due to conformational changes in the protein molecule. It was observed that ultrafiltration can promote an activity decrease proportional to the applied transmembrane pressure of a non-treatedlysozyme.However,whenathermallytreatedlysozyme(90°C)wasfiltered,noadditionale ff ect was observed due to the pore passage, independently of the applied pressure.","PeriodicalId":10566,"journal":{"name":"Comptes Rendus.
