"He esperado", "he vuelto" y "he vivido": su valor semántico en el español de México

Una demostración de Onoma, el conjugador en línea de verbos y neologismos verbales en español

We present Onoma, an online tool to conjugate and analyze Spanish verbs and verb neologisms. Its development results from of an important linguistic study in which the Spanish verbal system is approached with an innovative methodology. Both the evaluation and the noticeable success confirm its validity and interest.

Experiencias de envejecimiento en el México rural

Objective. To explore the aging experience among men and women older than 60 years, living in rural areas from the states of Guerrero and Morelos, Mexico. Materials and Methods. A qualitative study was conducted in povertystricken, underserved communities with less than 2 500 inhabitants. Semi-structured interviews were applied to collect data. Results. The aging experience is different accordi...

Calculations of the binding energies of weakly bound He–He–H, He–He–H− and He–H–H molecules

We searched for the existence of weakly bound He–He–H, He–He–H− and He–H– H molecules where the binding energies are expected to be of the order of degrees Kelvin. By employing the best empirical interaction between each pair of particles, we solved the Schrödinger equation for the triatomic systems using hyperspherical coordinates in the adiabatic approximation. We found no bound states for 4H...

Autoionization of He and Autodetachment of He- following Bombardment by H+, H2+, He+, and He Atoms

Thermodynamics of Liquid 'he- " He Mixtures

The osmotic pressure of 3He-4He solutions is shown to follow in a natural way from the separation of the specific heat in a quasiparticle contribution and a 4He-contribution. Expressions for important thermodynamic properties such as the chemical potentials, the internal energy, the entropy, specific heat, osmotic pressure, etc. are given for the case the quasiparticle gas can be treated as a n...
