Structure and thermodynamics of multi-component/multi-Yukawa mixtures
New small angle scattering experiments reveal new peaks in colloidal systems
(S.H. Chen et al) in the structure function S(k), in a region that was
inaccessible with older instruments. We propose here general closure of the
Ornstein Zernike equation, that is the sum of an arbitrary number of yukawas,
and that that will go well beyond the MSA . For this closure we get for the
Laplace transform of the pair correlation function . This function is easily
transformed into S(k) by replacing the Laplace variable by the Fourier
wariable. Although the method is general and valid for polydisperse systems, an
explicit continued fraction solution is found for the monodisperse case.Comment: 16 page

The Southeastern Sicily GPS network
The area located between Catania and Syracuse (Southeastern Sicily), characterised by the presence of the Simeto-Scordia-Lentini graben, was affected in the past by a strong seismicity as proved by the occurrence of seismic events strong enough to reach the XI degree of the MCS scale. In particular the January 11 th, 1693 (l = XI MCS) earthquake with a magnitude over 7.5 (estimated), caused huge damage and a great loss of human lives. Following the last seismic event which occurred on December 13th, 1990 (Ml = 5.4) which caused heavy damage and many victims in the Catania-Syracuse area, a geodetic Global Positioning System network (GPS) was set up with the aim of monitoring ground movements in one of the Italian areas subjected to high seismic risk, This "pace geodesy technique supplies high precision measurements and represent, a powerful new tool for investigating both regional stress fields and the evolution of local tectonic areas. The GPS network will allow the detection of ground movements with a centimetric accuracy through repeated surveys in time. The results obtained in two surveys carried out il1 1991 al1d 1993, are described in this paper
