ESCRITORAS DE LA GENERACIóN DEL CINCUENTA: CLAVES PARA UNA LECTURA POLíTICA
Olea,Raquel;

Abstract: in the production of denaturalization of women’s submission, historically inscribed in the religious-patriarchal society, bourgeoise and landowning, which evidences its own fall and decadence, women’s writing of the generation of 1950, proposes reading clues that play in the relationships that texts establish with: contemporary writing policies, the historical and social context (global and local), with the relationship with power and politics, and existentialism as a philosophical system. facing the hegemony of the marxist discourse that dominates the interpretation of the period, the feminist dictum private sphere is political as well offers a discursive clue to make intelligible the political discourses that these texts support.

Leishmaniosis visceral en un paciente con infección por VIH Visceral leishmaniasis in patient with HIV infection
Pilar Olea
Revista chilena de infectología , 2013,
Abstract: La leishmaniosis es una infección producida por parásitos del género Leishmania, transmitida por mosquitos hematófagos. Puede ocasionar infecciones subclínicas o manifestarse con compromiso cutáneo, mucoso o visceral. Esta última forma de presentación, que constituye la leishmaniosis visceral, es la más grave pudiendo llegar a ser fatal y en los pacientes con infección por VIH se presenta como una infección oportunista de difícil diagnóstico y tratamiento. Se reporta el caso de un paciente con infección por VIH con leishmaniosis visceral cuyo cuadro clínico se presentó como un síndrome febril prolongado con hepato-esplenomegalia, linfadenopatías y pancitopenia. Se plantearon los diagnósticos diferenciales de linfoma y otras infecciones oportunistas, como mico-bacteriosis. La demostración de amastigotes del parásito en el aspirado de médula ósea confirmó el diagnóstico. El paciente se trató con anfotericina B deoxicolato por 14 días y a los 2 meses presentó una recaída por lo cual recibió un segundo curso con el mismo medicamento por 21 días y se mantuvo posteriormente con profilaxis secundaria. Además se realizó cambio de la TAlRV por fracaso virológico e inmunológico. Ha continuado controlándose en forma ambulatoria por 29 meses presentando evolución satisfactoria, sin nuevas recaídas. Leishmaniasis is a parasitic disease caused by the protozoa of the genus Leishmania transmitted by sandfly bites. It causes subclinical infection and diverse clinical manifestations with cutaneous, mucosal or visceral involvement. The last one, called visceral leishmaniasis, is usually fatal without treatment and in VIH patients with deep immunosuppression, has been recognized as an opportunistic infection with a high degree of difficulty in diagnosis and treatment. We present the case of a patient with HIV infection and visceral leishmaniasis. The clinical presentation was a prolonged febril syndrome with hepatosplenomegaly, lymphadenopathy and pancytopenia. The diferential diagnosis was made with lymphoma and other opportunistic infections, as mycobacteriosis. The bone marrow aspirate reveled parasite amastigotes. The patient received treatment with amphotericin B deoxycholate for 14 days and 2 months after he relapsed. Then he was treated with the same drug for 21 days and after that he has been in prophylaxis for 29 months with good outcome, without any other relapse.

Abstract: En la producción de la desnaturalización de la sumisión de las mujeres, inscrita históricamente en el orden de una sociedad eclesial-patriarcal, burguesa y hacendal que evidencia su desmoronamiento y su decadencia, la escritura de las mujeres de la Generación del 50 propone claves de lectura que se juegan en las relaciones que los textos establecen con: las políticas escriturales de su contemporaneidad, el contexto histórico-social global y chileno, con la relación de las mujeres con el poder y la política y con el existencialismo como sistema filosófico. Frente a la hegemonía del discurso marxista que domina la interpretación de la época, el enunciado feminista lo privado también es político ofrece la clave discursiva de inteligibilidad de los discursos políticos que estos textos sostienen.

Mass, Angular Momentum and Thermodynamics in Four-Dimensional Kerr-AdS Black Holes
Rodrigo Olea
Physics , 2005, DOI: 10.1088/1126-6708/2005/06/023
Abstract: In this paper, the connection between the Lorentz-covariant counterterms that regularize the four-dimensional AdS gravity action and topological invariants is explored. It is shown that demanding the spacetime to have a negative constant curvature in the asymptotic region permits the explicit construction of such series of boundary terms. The orthonormal frame is adapted to appropriately describe the boundary geometry and, as a result, the boundary term can be expressed as a functional of the boundary metric, extrinsic curvature and intrinsic curvature. This choice also allows to write down the background-independent Noether charges associated to asymptotic symmetries in standard tensorial formalism. The absence of the Gibbons-Hawking term is a consequence of an action principle based on a boundary condition different than Dirichlet on the metric. This argument makes plausible the idea of regarding this approach as an alternative regularization scheme for AdS gravity in all even dimensions, different than the standard counterterms prescription. As an illustration of the finiteness of the charges and the Euclidean action in this framework, the conserved quantities and black hole entropy for four-dimensional Kerr-AdS are computed.
Regularization of odd-dimensional AdS gravity: Kounterterms
Rodrigo Olea
Physics , 2006, DOI: 10.1088/1126-6708/2007/04/073
Abstract: As an alternative to the Dirichlet counterterms prescription, I introduce the concept of Kounterterms as the boundary terms with explicit dependence on the extrinsic curvature K_{ij} that regularize the AdS gravity action. Instead of a Dirichlet boundary condition on the metric, a suitable choice of the boundary conditions --compatible with any asymptotically AdS (AAdS) spacetime-- ensures a finite action principle for all odd dimensions. Background-independent conserved quantities are obtained as Noether charges associated to asymptotic symmetries and their general expression appears naturally split in two parts. The first one gives the correct mass and angular momentum for AAdS black holes and vanishes identically for globally AdS spacetimes. Thus, the second part is a covariant formula for the vacuum energy in AAdS spacetimes and reproduces the results obtained by the Dirichlet counterterms method in a number of cases. It is also shown that this Kounterterms series regularizes the Euclidean action and recovers the correct black hole thermodynamics in odd dimensions.
Charged Rotating Black Hole Formation from Thin Shell Collapse in Three Dimensions
Rodrigo Olea
Physics , 2004, DOI: 10.1142/S021773230501827X
Abstract: The thin shell collapse leading to the formation of charged rotating black holes in three dimensions is analyzed in the light of a recently developed Hamiltonian formalism for these systems. It is proposed to demand, as a way to reconcile the properties of an infinitely extended solenoid in flat space with a magnetic black hole in three dimensions, that the magnetic field should vanish just outside the shell. The adoption of this boundary condition results in an exterior solution with a magnetic field different from zero at a finite distance from the shell. The interior solution is also found and assigns another interpretation, in a different context, to the magnetic solution previously obtained by Cl\'{e}ment and by Hirschmann and Welch.
Canonical variation of a Lorentzian metric
Benjamin Olea
Mathematics , 2015,
Abstract: Given a Lorentzian manifold $(M,g_L)$ and a timelike unitary vector field $E$, we can construct the Riemannian metric $g_R=g_L+2\omega\otimes\omega$, being $\omega$ the metrically equivalent one form to $E$. We relate the curvature of both metrics, especially in the case of $E$ being Killing or closed, and we use the relations obtained to give some results about $(M,g_L)$.
