Site-directed Mutagenesis of Cytochromec 6 from Synechocystissp. PCC 6803
(Elsevier, 1999)
This paper reports the first site-directed mutagenesis analysis of any cytochrome c 6, a heme protein that performs the same function as the copper-protein plastocyanin in the electron transport chain of photosynthetic ...

Homogeneous cooling state of a low-density granular flow
(American Physical Society, 1996)
The homogeneous cooling state of a granular flow of smooth spherical particles described by the Boltzmann equation is investigated by means of the direct simulation Monte Carlo method. The velocity moments and also the ...

Origin of density clustering in a freely evolving granular gas
(American Physical Society, 1999)
The physical mechanisms leading to the development of density inhomogeneities in a freely evolving low density granular gas are investigated. By means of the direct simulation Monte Carlo method, numerical solutions of the ...

Excitation of multiple giant dipole resonances: From spherical to deformed nuclei
(Elsevier, 1999)
The effect of deformation on the excitation of multiple giant dipole resonances is studied. Analytical expressions are derived in the framework of the interacting boson model for the energies and E1 properties of giant ...

Typification of two species of Vicia L. (Fabaceae) described by Boissier in N. Africa
(Palermo : Published under the auspices of OPTIMA by the Herbarium Mediterraneum Panormitanum, 1997)
Two species of Vicia subgen. Cracca from the S. W. Mediterranean, V. durandii Boiss, and V. momardii Boiss., are typified. The former name is referable to V. altissima Desf. and the other becomes the correct name for the ...

Glasslike relaxation in a one-dimensional bonded-fluid model
(American Institute of Physics Publising LLC, 1991)
A Monte Carlo investigation of the linear and nonlinear relaxation of a one-dimensional bonded fluid is presented. The simulation shows that the model possesses many of the qualitative properties of the glass-forming ...

Un método de elementos finitos incondicionalmente estable en norma uniforme para resolver las ecuaciones de Euler 2D
(Universitat Politècnica de Catalunya, 1993)
Este trabajo presenta dos algoritmos de tipo transporte e interpolación con Elementos Finitos para la resolución numérica de las ecuaciones de Euler para flujos incompresibles bidimensionales en todo el espacio IR2. En la ...

On the approximate and null controllability of the Navier-Stokes equations
(Society for Industrial and Applied Mathematics, 1999-06)
This paper presents some known results on the approximate and null controllability of the Navier–Stokes equations. All of them can be viewed as partial answers to a conjecture of J.-L. Lions.

Self-diffusion in freely evolving granular gases
(American Institute of Physics, 1994)
A self-diffusionequation for a freely evolving gas of inelastic hard disks or spheres is derived starting from the Boltzmann–Lorentz equation, by means of a Chapman–Enskog expansion in the density gradient of the tagged ...
