The non-perturbative unquenched quark model
In recent years states in the quarkonium spectrum not expected in the naive quark model have appeared and created a lot of interest. In the theoretical side the study of the effect of meson-meson thresholds in the spectrum have been performed in different approximations. In a quark model framework, and in the spirit of the Cornell model, when a meson-meson threshold is included, the coupling to all the quark-antiquark states have to be considered. In practice only the closest states are included perturbatively. In this contribution we will present a framework in which we couple quark-antiquark states with meson-meson states non-perturbatively, taking into account effectively the coupling to all quark-antiquark states. The method will be applied to the study of the X(3872) and a comparison with the perturbative calculation will be performed

Soil radon pulses related to the initial phase of volcanic euruptions
Soil radon behaviour related to the initial phase of volcanic eruptions is analysed from reported values related to the explosivity of four American stratovolcanoes: El Chichon (1982) and Popocatepetl (1994) in Mexico, Poas
(1987-1990) in Costa Rica and Cerro Negro (1995) in Nicaragua. The measurements in the field were performed with solid-state nuclear track detectors and electrets.
The ratio between the magnitudes of the radon in soil peaks generated when the eruptive period started and the average radon values corresponding to quiescence periods indicate a dependence on the Volcanic Eruptive Index for each one of the eruptive periods
Water chemistry and soil radon survey at the Poas volcano (Costa Rica)
Radon-in-soil monitoring at the Poas volcano (Costa Rica) has been performed together with water chemistry
from the hot crater lake since 1981 and 1983 respectively. The results are discussed as a function of the eruptive
evolution of the volcano over a 13 years period (1981-1994). It is shown that no definitely clear precursory radon
signals have been recorded. On the contrary, ionic species concentrations are likely to be considered good precursors,
together with the temperature variations of the crater lake water
