ASYMPTOTIC STRUCTURE OF SIMPLE COSMOLOGICAL MODELS

Anales (Asociación Física Argentina), 2013
The future null infinity for all non-contracting Robertson-Walker spacetimes is studied systematically. A theorem is proved which establishes the expected relation between the nature of g + and the appearance or absence of cosmic event horizons.

Inflation in an Inhomogeneous Cosmology

, 1995
We present results on the non-linear dynamics of a wide class of inhomogeneous cosmological models with irrotational dust and vanishing magnetic part of the Weyl tensor, with a cosmological constant Lambda > 0.

Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

Revisiting olivine‐phyric shergottites: Pyroxene crystallization pressure and the role of undercooling

Meteoritics &Planetary Science, EarlyView.
Abstract Shergottites are the most abundant meteorites from Mars and a major source of information on magma reservoirs, transport, and eruption, particularly in the late Hesperian northern hemisphere. Conflicting interpretations have arisen on the crystallization conditions of pyroxene in olivine‐phyric shergottites.

Extracting vitalities: Cuts in Indigenous women's bodies‐territories (Brazil)

Medical Anthropology Quarterly, EarlyView.
Abstract In this article, I explore the connections between the medicalization of childbirth and environmental devastation through Guarani‐Mbyá understandings of life and the living. I argue that the cuts made to Guarani‐Mbyá women's vaginas (episiotomies) in Brazilian hospitals are experienced and situated on the same cosmopolitical level as the cuts ...

Diet and leishmaniasis in the Ecuadorian Amazon

Medical Anthropology Quarterly, EarlyView.
Abstract In Ecuador's Amazon, Indigenous communities affected by leishmaniasis often modify their diets as part of their health‐seeking practices. Drawing on qualitative research with sixty‐eight participants from seven Indigenous groups, this study explores how and why patients’ diets shift in pursuit of healing from leishmaniasis.

Spacetime Foam and the Cosmological Constant

, 2007
In the saddle point approximation, the Euclidean path integral for quantum gravity closely resembles a thermodynamic partition function, with the cosmological constant playing the role of temperature and the "density of topologies" acting as an
