El ferrocarril a Igualada: la lluita pel progrés (1852-1893)

Hom veié que la lluita pel progrés era la lluita pel ferrocarril, i aquesta es convertí en el principal eix de les aspiracions igualadines durant les últimes dècades del segle XIX. La pregunta clau que cal fer-se és fins a quin punt l"aïllament ferroviari d"Igualada roman per causes pròpies o obeeix a plantejament més amplis. A retop d'aquesta, sorgeixen moltes altres preguntes: en quina mesura la solució del problema estava en mans igualadines?; eren aquests realment conscients de la seva situació i de les seves possibilitats?; fou correcta la seva actuació?; quines eren les condicions reals, tant locals com foranies, que jugaven en la qüestió ferroviària en particular i en l"econòmica en general?. Aquesta i d'altres preguntes són les que cal plantejar-se per tal de comprendre veritablement el problema del perllongat aïllament ferroviari d'Igualada.

Thomas-Fermi theory for atomic nuclei revisited

The recently developed semiclassical variational Wigner-Kirkwood (VWK) approach is applied to finite nuclei using external potentials and self-consistent mean fields derived from Skyrme inter-actions and from relativistic mean field theory. VWK consist s of the Thomas-Fermi part plus a pure, perturbative h 2 correction. In external potentials, VWK passes through the average of the quantal values of the accumulated level density and total en energy as a function of the Fermi energy. However, there is a problem of overbinding when the energy per particle is displayed as a function of the particle number. The situation is analyzed comparing spherical and deformed harmonic oscillator potentials. In the self-consistent case, we show for Skyrme forces that VWK binding energies are very close to those obtained from extended Thomas-Fermi functionals of h 4 order, pointing to the rapid convergence of the VWK theory. This satisfying result, however, does not cure the overbinding problem, i.e., the semiclassical energies show more binding than they should. This feature is more pronounced in the case of Skyrme forces than with the relativistic mean field approach. However, even in the latter case the shell correction energy for e.g.208 Pb turns out to be only ∼ −6 MeV what is about a factor two or three off the generally accepted value. As an adhoc remedy, increasing the kinetic energy by 2.5%, leads to shell correction energies well acceptable throughout the periodic table. The general importance of the present studies for other finite Fermi systems, self-bound or in external potentials, is pointed out.

Classical references and their significance in The Magic Mountain by Thomas Mann

Although Thomas Mann’s novel The Magic Mountain has been the object of innumerable studies, this paper suggests that so far none of these has given truly close attention to the significance of the classical references in this novel with regard to the search for a true humanism. This is probably owing to the generally held belief that the influence of the classical tradition is relatively inconsequential in relation to the ample conjunction of philosophical ideas on which the novel is based. This article takes a differing view and, through a close analysis and comment of the explicit and implicit classical notions in the text, concludes that these ideas are also a valuable key to a greater comprehension of the ideological design of the main character, Hans Castorp, and to a certain degree they also help to continue to reflect on the most enigmatic and controversial episode of the novel: the young protagonist’s descent to the plain from the magical mountain (Zauberberg) in order to take part in the great tragedy of World War I, alien as is any war to the prevalent but ultimately futile desire that love (Liebe) should in the end prevail in the life of humans.

De More a Moore : de la utopia al cos, i a l’inrevés

Through the graphic novel V for Vendetta by Alan Moore and David Lloyd, I problematize here the act of classification of the subgenres within each genre. This is a literary study that aims to reflect on the utopian genre. It is a genre which requires in order to be understood a consideration of society and its organization. The concept of society cannot be properly discussed without mentioning the surface on which it is based: people with their selves and their bodies. Institutions and conventions act subtly and constantly on us, offering more or less free roles, usually related to a particular physical appearance, as may be the mode of dress, or gesture- and generating a negotiation between our desires and our duties. In other words, they act on us to transform us into people suitable for the smooth running of the community
