LAGOvirtual a collaborative environment for the large aperture GRB observatory
(2009-10-20)
We present the LAGOVirtual Project: an ongoing project to develop platform to collaborate in the Large Aperture GRB Observatory (LAGO). This continental-wide observatory is devised to detect high energy (around 100 GeV) ...
GridChoque: a grid environment to experiment on spherically symmetric general relativistic radiation hydrodynamics
(2009-10-20)
This paper presents a Grid application, GridChoque: a distributed, and a grid based, environment devised to explore the general relativistic spherically radiative stellar collapse using several tools of calculus and ...
Low temperature resistance in saplings and ramets of Polylepis sericea in the Venezuelan Andes
(Acta Oecologica 35(5): 610–613, 2009-10)
The frequent occurrence of all year-round below zero temperatures in tropical high mountains constitutes a most stressful climatic factor that plants have to confront. Polylepis forests are found well above
the continuous ...
Interception of water by pastures of Pennisetum clandestinum Hochst. ex Chiov. and Melinis minutiflora Beauv
(Agricultural and Forest Meteorology 149: 1616-1620, 2009-10)
The conversion of montane cloud forests into pastures for grazing cattle is the main cause of important impacts on rivers and streams in most of the Andes. In order to evaluate the effects of vegetation changes we need to ...

Se registra el tiempo de supervivencia de formas metacíclicas de Trypanosoma cruzi,
obtenidas del tracto digestivo de Rhodnius prolixus, sobre alimentos contaminados experimentalmente.
Observaciones entre 1h y 18h ...
Water cherenkov detectors response to a Gamma Ray Burst in the large aperture GRB observatory
(http://arxiv.org/, 2009-06-04)
In order to characterise the behaviour of
Water Cherenkov Detectors (WCD) under a sudden
increase of 1 GeV - 1 TeV background photons from
a Gamma Ray Burst (GRB), simulations were conducted
and compared to data acquired ...
