Abstract:
O presente artigo aborda as representa es sociais da pobreza urbana no Brasil. O objeto de estudo é, por um lado, o conjunto de discursos e imagens sobre a favela na imprensa e, por outro lado, as auto-representa es visuais de favelas e periferias da cidade do Rio de Janeiro, na virada do século XXI. O objetivo é analisar o uso da categoria favela na forma o do imaginário social da cidade e, ao mesmo tempo, investigar como se constrói o olhar periférico nas representa es fotográficas dos moradores de favelas. O método empregado baseia-se nas contribui es de Pierre Bourdieu e de Roland Barthes para a análise do discurso e nas contribui es da antropologia visual e da história cultural para a análise da fotografia enquanto campo documental na etnografia. Os resultados revelam um movimento de constitui o de novas subjetividades no cenário das grandes cidades dos anos 90, por meio da a o de ONG’s nas favelas, criando um espa o de reflex o sobre si e sobre o outro e de afirma o de novas identidades.

Abstract:
The ANTARES (Astronomy with a Neutrino Telescope and Abyss environmental RESearch) Collaboration constructed and deployed the world's largest operational underwater neutrino telescope, optimised for the detection of Cherenkov light produced by neutrino-induced muons. The detector has an effective area of about 0.1 square km and it is a first step towards a kilometric scale detector. The detector consists of a three-dimensional array of 884 photomultiplier tubes, arranged in 12 lines anchored at a depth of 2475 m in the Mediterranean Sea, 40 km offshore from Toulon (France). An additional instrumented line is used for environmental monitoring and for neutrino acoustic detection R&D. ANTARES is taking data with its full twelve line configuration since May 2008 and had been also doing so for more than a year before a five and ten line setups. First results obtained with the 5 line setup are presented.

Abstract:
This paper is a reflection on the relations between an individual and the different groups to whom he belongs during the course of his life. The aim of this paper is to describe these relations in the terms of the paradigm of a matrix and an intruder. We believe that this interpretation can shed an interesting light on the individual development. It can also provide a key of interpretation of some fundamental life events that may be of help for therapists. The two roles are distinct, but in time an individual can assume either or even both at the same time. We argue that this duality could be the expression of the opposing poles of a Jungian archetype. We also elaborate on the relations of this archetype with the septenary model of the psyche of the Swiss psychoanalyst Charles Baudouin and the schizo-paranoid and depressive phases described by Melany Klein. We conclude with a reference to Etruscan and early Roman art in relation to the emptiness of the matrix role and the existential solitude of man.

Abstract:
The aim of this paper is to explore the connections between the Jungian concept of collective unconscious, the Bionian group dynamics and the septenary schema elaborated by the Swiss psychoanalyst C. Baudoin, as a synthesis of the Freudian and Jungian topics. Borrowing (marauding) concepts from the above theories, we propose a theoretical analytical framework for our experience with the ASTRAG group training association in terms of psychoanalytical instances and their relations in the analytical group situation. We describe the history and activity of ASTRAG that we founded in 2005 at Geneva, Switzerland. This association has trained more than 100 people interested in group dynamics over 14 years. One of the main features of this training is that there is no money exchange of any sort. Participation is free and the training staff is made of volunteers who are not remunerated. Participants are accepted with no entry interview. We then conclude with some considerations on the effect of gratuity on the group analytical work.

Abstract:
We show the results of two dimensional general relativistic inviscid and isothermal hydrodynamical simulations comparing the behavior of co-rotating (with respect to the black hole rotation) and counter-rotating circumbinary quasi-Keplerian discs in the post merger phase of a supermassive binary black hole system. While confirming the spiral shock generation within the disc due to the combined effects of mass loss and recoil velocity of the black hole, we find that the maximum luminosity of counter-rotating discs is a factor ~(2-12) higher than in the co-rotating case, depending on the spin of the black hole. On the other hand, the luminosity peak happens ~10 days later with respect to the co-rotating case, for a binary with a total mass M~10^6 M_\odot. Although the global dynamics of counter-rotating discs in the post merger phase of a merging event is very similar to that for co-rotating discs, an important difference has been found. In fact, increasing the spin of the central black hole produces more luminous co-rotating discs while less luminous counter-rotating ones.

Abstract:
We propose a simple model for an optically thick radiative torus in local thermodynamic equilibrium around a Kerr black hole. The hydrodynamics structure, which is not affected by the radiation field, is the same as for the so--called polish doughnuts. Under the assumption of isentropic fluid and polytropic equation of state, a simple stationary and axisymmetric solution to the relativistic radiation hydrodynamics equations is possible, for which the temperature of the torus scales like the specific enthalpy. The astrophysical relevance of the model is briefly discussed.

Abstract:
Radiation by elementary sources is a basic problem in wave physics. We show that the time-domain energy flux radiated from electromagnetic and acoustic subwalength sources exhibits remarkable features. In particular, a subtle trade-off between source emission and absorption underlies the mechanism of radiation. This behavior should be observed for any kind of classical waves, thus having broad potential implications. We discuss the implication for subwavelength focusing by time reversal with active sources.

Abstract:
ALICE, the experiment dedicated to the study of heavy ion collisions at the LHC, uses an object-oriented framework for simulation, reconstruction and analysis (AliRoot) based on ROOT. Here, we describe the general ALICE simulation strategy and those components of the framework related to simulation. Two main requirements have driven the development of the simulation components. First, the possibility to run different transport codes with the same user code for geometry and detector response has led to the development of the Virtual Monte Carlo concept. Second, simulation has to provide tools to efficiently study events ranging from low-multiplicity pp collisions to Pb-Pb collisions with up to 80000 primary particles per event. This has led to the development of a variety of collaborating generator classes and specific classes for event merging.

Abstract:
We prove that the linearization of a germ of holomorphic map of the type $F_\lambda(z)=\lambda(z+O(z^2))$ has a $ C^1$--holomorphic dependence on the multiplier $\lambda$. $C^1$--holomorphic functions are $ C^1$--Whitney smooth functions, defined on compact subsets and which belong to the kernel of the $\bar{\partial}$ operator. The linearization is analytic for $|\lambda|\not= 1$ and the unit circle $S^1$ appears as a natural boundary (because of resonances, i.e. roots of unity). However the linearization is still defined at most points of $S^1$, namely those points which lie ``far enough from resonances'', i.e. when the multiplier satisfies a suitable arithmetical condition. We construct an increasing sequence of compacts which avoid resonances and prove that the linearization belongs to the associated spaces of ${\cal C}^1$--holomorphic functions. This is a special case of Borel's theory of uniform monogenic functions, and the corresponding function space is arcwise-quasianalytic. Among the consequences of these results, we can prove that the linearization admits an asymptotic expansion w.r.t. the multiplier at all points of the unit circle verifying the Brjuno condition: in fact the asymptotic expansion is of Gevrey type at diophantine points.
