Le rose del deserto. La quarta sponda fra arditismo e "colonialismo straccione"
No full textAl film di Monicelli, liberamente ispirato al romanzo di Mario Tobino del 1951, Il deserto della Libia, dedica un’analisi particolareggiata Domenico Guzzo, giungendo a leggere il velleitario colonialismo italiano come prosecuzione e riflesso del colonialismo interno, e in generale di una dinamica di costruzione nazionale mai davvero realizzata e quindi sempre debole sia internamente che esternamente
L'assordante silenzio nero e le ostentate rivendicazioni rosse: gli antitetici modelli comunicativi dei due terrorismi italiani
No full textThe author introduces a comparative examination among the antithetical communicative expressions of the two terrorist experiences, appeared in the second Italian postwar period: the "black carnages" and the "red paramilitary attacks". Starting from their inverse correlation among the "meaning" and the "meant" of the terrorist "sign", the author reconstruct the opposite languages communicated by these different typologies of attempts

Integrability of close encounters in the spatial restricted three-body problem
No full textWe extend to the spatial case a technique of integration of the close encounters formulated by Tullio Levi-Civita for the planar restricted three-body problem. We consider the Hamiltonian introduced in the Kustaanheimo-Stiefel regularization and construct a complete integral of the related Hamilton-Jacobi equation by means of a series convergent in a neighborhood of the collisions with the primary or secondary body
The accelerated Kepler problem
No full textThe accelerated Kepler problem (AKP) is obtained by adding a constant
acceleration to the classical two-body Kepler problem. This setting models the dynamics
of a jet-sustaining accretion disk and its content of forming planets as the disk loses linear
momentum through the asymmetric jet-counterjet system it powers. The dynamics of the
accelerated Kepler problem is analyzed using physical as well as parabolic coordinates. The
latter naturally separate the problem's Hamiltonian into two unidimensional Hamiltonians.
In particular, we identify the origin of the secular resonance in the AKP and determine analytically the radius of stability boundary of initially circular orbits that are of particular interest
to the problem of radial migration in binary systems as well as to the truncation of accretion
disks through stellar jet acceleration
Effective Dark Matter Halo Catalog in f (R) Gravity
No full textWe introduce the idea of an effective dark matter halo catalog in f(R) gravity, which is built using the effective density field. Using a suite of high resolution N-body simulations, we find that the dynamical properties of halos, such as the distribution of density, velocity dispersion, specific angular momentum and spin, in the effective catalog of f(R) gravity closely mimic those in the cold dark matter model with a cosmological constant (ΛCDM). Thus, when using effective halos, an f(R) model can be viewed as a ΛCDM model. This effective catalog therefore provides a convenient way for studying the baryonic physics, the galaxy halo occupation distribution and even semianalytical galaxy formation in f(R) cosmologies
POLLEN DEVELOPMENT IN LIRIODENDRON-TULIPIFERA - SOME UNUSUAL FEATURES
No full textPollen development in Liriodendron tulipifera has some unusual features. Two arrangements in tetrads could be detected: isobilateral and decussate types. The occurrence of one or the other pattern seems to be random. The sulcus position is marked early by an exine fold forming at the beginning of wall deposition at the distal pole of tetrad cells. During increasing microspore volume, the exine outgrowth is unfolded, then stretched and finally broken up, thus exposing the intine below. Plastids are usually excluded from the generative cell, indicating that their inheritance is predominantly maternal. Nevertheless our cytological results give evidence of a trace paternal transmission of plastids. Some evolutionary considerations are mad
