Potenciometria e Fluxo Subterrâneo no Aqüífero Aluvionar do Baixo Curso do Rio Macaé, Município de Macaé-RJ

Macaé city is inserted in the coastal portion of the Northern region of Rio de Janeiro State, Brazil. The study accomplished in the alluvial aquifer of the Macaé river lower course, whose waters fulfill the domestic needs of a significant part of the rural and peripheral population of the city, comprised the neighborhoods of Córrego do Ouro, Fazenda Severina, Virgem Santa and Aterrado do Imburo. Results comprise the hydrodynamic studies that lead to the elaboration of a potentiometric map in that alluvial aquifer. The potentiometry shows the relationship between the surface and subsurface water. The Macaé River has an effluent character in the studied area. Aquifer recharge is associated to the topographical adjacent higher grounds and discharge is towards the Macaé river channel and river mouth. The hydrographs of water level temporal variation suggest a possible hydraulic connection among the monitored water points, evidencing a lateral continuity in the area

Discriminating among the theoretical origins of new heavy Majorana neutrinos at the CERN LHC

A study on the possibility of distinguishing new heavy Majorana neutrino models at LHC energies is presented. The experimental confirmation of standard neutrinos with non-zero mass and the theoretical possibility of lepton number violation find a natural explanation when new heavy Majorana neutrinos exist. These new neutrinos appear in models with new right-handed singlets, in new doublets of some grand unified theories and left-right symmetrical models. It is expected that signals of new particles can be found at the CERN high-energy hadron collider (LHC). We present signatures and distributions that can indicate the theoretical origin of these new particles. The single and pair production of heavy Majorana neutrinos are calculated and the model dependence is discussed. Same-sign dileptons in the final state provide a clear signal for the Majorana nature of heavy neutrinos, since there is lepton number violation. Mass bounds on heavy Majorana neutrinos allowing model discrimination are estimated for three different LHC luminosities.Comment: 7 pages, 5 figure

Bounds on the electromagnetic interactions of excited spin-3/2 leptons

We discuss possible deviations from QED produced by a virtual excited spin-3/2 lepton in the reaction $e^+e^- \longrightarrow 2\gamma$. Data recorded by the OPAL Collaboration at a c.m. energy $\sqrt{s} = 183 GeV$ are used to establish bounds on the nonstandard-lepton mass and coupling strengths.Comment: Latex, 5 pages, 7 ps figures.

Romantic-Gothic Sepulchres: Intersections of Death, Memory, and Mourning in Film (1907-1958)

In this study, I explore the representation of death, memory, mourning, and oneirism in specific transnational cinematic works from 1907 to 1958. Looking beyond psychoanalytic theories, I revise current theorisations of the Gothic through a formal-aesthetic methodological lens and propose new, cross-cultural avenues that have been heretofore neglected. I suggest that Romanticism and the Gothic have become catch-all terms whose usage may seem convenient to speak and write about film, but that nonetheless overlook the unique way the Gothic and Romantic doctrines meet and meld on the screen. I work towards an assessment of this singular relationship in cinema—which I describe as the Romantic-Gothic mode—by providing analyses of both US and European works. In so doing, I propose an interpretive strategy that highlights and investigates the implications of moving the afterlife out of the graveyard and into the space of the cinema. I endeavour to map the geographic, temporal, and psychological dislocations of the characters, which, I argue, are structured upon the contact between the sensing human body and the circumambient life. I examine the mediation of pastness by certain places and objects that insistently actualise gone-by events and thus question the notion of the past as an unequivocal cause for the present and future. I suggest that the encounter of the dwellers with what I call memory-objects in their lonely walks through the foreignness of private and outdoor spaces re/creates identity. A nodal point in the project concerns the idea that the Romantic-Gothic mode is a map of sensory memories where mourning, forgetfulness, and the annihilation of the self in time, space, and mind germinate. Finally, in broad outline, my work offers a starting point for a critical reappraisal of Romantic and Gothic art in film
