A virtual element discretisation for the numerical approximation of three-field formulation linear poroelasticity introduced in R. Oyarzúa and Ruiz-Baier, (SIAM J. Numer. Anal. 54 2951–2973, 2016) is proposed. The treatment extended to include also transient case. Appropriate projector operators are they assist deriving energy bounds time-dependent discrete problem. Under standard assumptions o...

in this research, the production of plum pastille-like with starch and gelatin was studied. thirteen formulation of plum pastille-like were prepared according to a second-order composite rotatable design (with five central points). response surface methodology (rsm) was used to optimize product formulation with: gelatin concentration ranging from 3.85 to 6.925 % (w/w), and starch concentration ...
