A Symmetry-Adapted Algebraic Approach to Molecular Spectroscopy
(Scielo, 1996)
We apply a symmetry-adapted algebraic model to the vibrational excitations in D_3h and T_d molecules. A systematic procedure is used to establish the relation between the algebraic and configuration space formulations. In ...

The modification of classical Hahn polynomials of a discrete variable
(Taylor & Francis, 1995)
We consider a modi cation of moment functionals for the Hahn classical polynomials of a discrete variable by adding two mass points at the ends of the interval, i.e., in x = 0 and x = N 1. We obtain the resulting orthogonal ...

Evidencias morfogenéticas cuaternarias en el Karst de la Sierra del Endrinal (Grazalema, Cádiz)
(Sociedad Geológica de España, 1998)
The geomorphological observations made until now reveal a long morphogenic history for the karst of the Eridrinal: mountains; going back to pre-Quaternary times. The erosion surfaces mapped (Sl, S2 and 53) have å biostatic ...

Binding of [125I]Iodocyanopindolol by Rat Harderian Gland Crude Membranes: Kinetic Characteristics and Day-Night Variations
(Biochemical Society, 1996-10-01)
The Harderian glands are innervated by sympathetic fibers originating in the superior cervical ganglia. The aim of this study is to characterize the /3-adrenergic receptors in the rat Harderian gland. The characteristics ...

Molecular-dynamics ensembles: Fluctuations and correlations near the phase transitions
(American Institute of Physics Publising LLC, 1993)
Computer simulations of liquid and solid systems very close to the melting-freezing transition zone have been performed for the microcanonical, canonical, and isothermal-isobaric molecular-dynamics ensembles. Temperature, ...

Amino acid transport systems required for diazotrophic growth in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 1995)
Uptake of 16 amino acids by the filamentous, heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 was characterized with regard to kinetic parameters of transport, intracellular accumulation of the transported ...
