In atmospheric chemistry, a parameter called residence time is defined for each gas as T=M/F, where M represents the mass of the gas in the atmosphere and F is the total average influx or outflux, which in time averages are equal. In this brief commu

Considering our atmosphere as a steady viscous gaseous envelope that co-rotates with the Earth, we obtain a solution for the form in which this induced rotational effect decreases as a function of the distances to the centre of the Earth and to the r

Context. We have studied clusters of self-gravitating collisionless Newtonian bosons in their ground state and in the presence of the cosmological constant to model dark haloes of dwarf spheroidal (dSph) galaxies. Aims. We aim to analyse the influenc

We explore the possibility of discriminating dark energy models from the study of the growth of matter perturbations. For the sake of simplicity, instead of dealing with a great number of models, we have chosen a simple model of dark energy (px = ω0

We investigate the cosmology of x-matter with pressure, px, and density, ρx, related by px=w0ργx(w0 0). For γ >1, this x-matter behaves like a cosmological constant when a≪ a0 (a being the scalefactor and a0 the scalefactor at present) and like

The gravitational instability of free and dilute Newtonian boson clouds has been examined. For collisionless Newtonian boson clouds with a uniform unperturbated Bose gas density, it is deduced that the gravitational instability will never give rise t

We calculate the coherent and incoherent scattering functions for free atoms at finite temperature. This is performed within a finite-temperature Thomas-Fermi method recently proposed by us, which avoids — artificial — confining cells of the Wign

We obtain an analytic expression for the total energy of a metallic cluster formed by N atoms of valence v and with net charge Q, by solving variationally the extended Thomas–Fermi version of density functional theory within the spherical jellium m
