In this paper we deal with the problem of the generation of internal waves at the bottom of convective zone in solar-type stars, and with the transport process linked to the non-adiabatic propagation of these waves through the stable radiative region. The main improvement with respect to the previous papers in this series comes from the convection

We show that a wide variety of processes lead, in certain limit, to a simple generalization of the negative binomial distribution. Its properties are studied in detail and used to derive an important result in the theory of avalanches.

We present observations and analyses of seven Galactic O stars of type O6 and earlier. The analyses are carried out using NLTE plane-parallel, hydrostatic models as well as NLTE spherical models with mass-loss. With detailed calculations for the former and simulations for the latter, it is shown that the flux blocking due to UV metal lines is

We study the bounds that can be obtained on four-fermion contact terms from the experimental data for e+p-->ν¯X obtained at DESY HERA and pp¯-->e+/- ν(-) measured at the Fermilab Tevatron. We compare these bounds with the ones available in the literature. Finally, we apply these results to study the compactification radius in theories with large

Far-IR Infrared Space Observatory (ISO) maps of four Seyfert galaxies are presented and compared with their optical counterpart images. The far-IR maps resemble the optical images of these galaxies when degraded to the ISO resolution. The spatial extension of the far-IR maps is also comparable to the optical extension of these objects, an
