A phenomenological model for wall effects on the deformation of an ellipsoidal drop in viscous flow
No full textThe simple phenomenological model developed by Maffettone and Minale (J Non-Newt Fluid Mech 78:227-241, 1998) for the deformation of a single ellipsoidal drop in a viscous flow is extended here to predict the drop deformation in confined viscous flows. The model is capable of describing the transient evolution of an ellipsoidal drop subjected to a generic flow field. The steady-state predictions are analytical and recover the theoretical limits of Shapira and Haber (Int J Multiph Flow 16:305-321, 1990) for steady small deformation of a drop in a confined simple shear flow. Model predictions are compared with data available in the literature that cover a wide range of parameter values, and the agreement is good

Mental Disease and Imputability: intervalla insaniae and Regime of Custody. From D. 1.18.14 (Macer De iudiciis publicis libri XIV) to the Contemporary Debate
No full textThe Macer's passage preserved in D. 1.18.14 (together with Ulpian's D. 1.18.13.1 and Modestinus' D. 48.9.9.2) faces the matter of the imputability of a subject author of a crime, but unfit to plead because of mental disease. In our fragment the principle which denied the imputability in such a case, already existing in the Roman legal system, is restated in a rescript sent by Marcus Aurelius and the son Commodus to the functionary Scapula Tertullus concerning a certain Aelius Priscus, murderer of his mother. The emperors ask to investigate the possible presence of simulatio dementiae and mainly intervalla insaniae prescribing the measure of the detention, if necessary also in prison. The fact forces us to reflect about the high level of dogmatic speculation of the Severan jurists. In more criminological sense, instead, the main problem is represented by the social value given to a homicide inside the family and in particular toward a parent, a crime so atrocious to be perceived by the public opinion, now as much as in the past, “unnatural” or better even “against-natur”, on the basis of a kind of self-protection mechanism

No full textDeformation of a non-newtonian ellipsoidal drop in a non-newtonian matrix: extension of Maffettone–Minale model
No full textA phenomenological model for the dynamics of a buoyancy free non-Newtonian drop immersed in a non-Newtonian fluid subjected to a flow field with an arbitrary uniform velocity gradient is presented. The model is based on the assumption that the drop deforms while remaining ellipsoidal and the volume is preserved. The analytical limits of Taylor for both small deformations and high viscosity ratios are exactly recovered. Also, the affine deformation limit is recovered under the appropriate conditions. In addition, the second-order theory for non-Newtonian systems [F. Greco, J. Non-Newtonian Fluid Mech. 107 (2002) 111–131] is also recovered to within a minor term. As a consequence, the major and minor drop semiaxes, together with the drop angle, properly degenerate into the analytical limits, while the third semiaxis differs only slightly from the exact theory. Model predictions are compared with experimental data for both Newtonian and non-Newtonian systems, throughout a significant range of parameters values

No full textThe deformation of an ellipsoidal drop under viscous flow conditions
No full textA previously developed phenomenol. model for the deformation of a droplet immersed in a fluid subjected to a flow field (P. L. Maffettone, M. Minale; 1998) is tested to predict the drop transient behavior following the flow start-up and its relaxation upon cessation of flow. The model was then compared with expts. in which a shear device consisting of a parallel plate app. was used, and the fluids used were 2 immiscible polymers, polyisobutylene and polydimethylsiloxane. Comparison of theor. and exptl. data showed that both the start-up and the relaxation upon cessation fo flow is accurately predicted. The study is of interest with respect to blending and processing polymers
