L'adulterio come strumento sociale: confronto tra Anna Karenina e Lady Chatterley

Lo scopo di questo lavoro è confrontare due opere, Anna Karenina di Lev Tolstoj e L’amante di Lady Chatterley di David Herbert Lawrence e dimostrare che essi non hanno in comune solo il tema dell’adulterio, ma anche e soprattutto l’averlo inteso come strumento di ribellione sociale. In Tolstoj troviamo l’adulterio censurato nel corso della narrazione, poiché esso viene condannato sia dalla società che dall’autore stesso, che aveva come intento dare una lezione morale. Lawrence invece esalta e descrive l’adulterio, poiché nel suo caso diventa lo strumento di scoperta dell’amore vero e di ritorno al primitivismo a dispetto della civiltà industrializzata. Quindi, pur appartenendo a due epoche diverse e a due società con differenti visioni circa matrimonio e famiglia, le due eroine sono similari per il coraggio che dimostrano nell’andare contro le rispettive società.

Numerical and semi-analytical models of sliding masses: application to the 1783 Scilla tsunamigenic landslide

The Scilla rock avalanche occurred on 6 February 1783 along the coast of the Calabria region (southern Italy), close to the Messina Strait. It was triggered by a mainshock of the Terremoto delle Calabrie seismic sequence, and it induced a tsunami wave responsible for more than 1500 casualties along the neighboring Marina Grande beach. The main goal of this work is the application of semi-analtycal and numerical models to simulate this event. The first one is a MATLAB code expressly created for this work that solves the equations of motion for sliding particles on a two-dimensional surface through a fourth-order Runge-Kutta method. The second one is a code developed by the Tsunami Research Team of the Department of Physics and Astronomy (DIFA) of the Bologna University that describes a slide as a chain of blocks able to interact while sliding down over a slope and adopts a Lagrangian point of view. A wide description of landslide phenomena and in particular of landslides induced by earthquakes and with tsunamigenic potential is proposed in the first part of the work. Subsequently, the physical and mathematical background is presented; in particular, a detailed study on derivatives discratization is provided. Later on, a description of the dynamics of a point-mass sliding on a surface is proposed together with several applications of numerical and analytical models over ideal topographies. In the last part, the dynamics of points sliding on a surface and interacting with each other is proposed. Similarly, different application on an ideal topography are shown. Finally, the applications on the 1783 Scilla event are shown and discussed.
