Transcription of glutamine synthetase genes (glnA and glnN) from the cyanobacterium Synechocystis sp. strain PCC 6803 is differently regulated in response to nitrogen availability
(American Society for Microbiology, 1997)
In the cyanobacterium Synechocystis sp. strain PCC 6803 we have previously reported the presence of two different proteins with glutamine synthetase activity: GSI, encoded by the glnA gene, and GSIII, encoded by the glnN ...

Brownian motion in a granular gas
(American Physical Society, 1999)
The dynamics of a heavy particle in a gas of much lighter particles is studied via the Boltzmann-Lorentz equation with inelastic collisions among all particles. A formal expansion in the ratio of gas to tagged particle ...

Reorientation and coupling effects in polarized heavy ion fusion
(Elsevier, 1992)
A simple model to understand the reaction mechanisms in the fusion of polarized heavy ions based on tidal symmetry, the sudden approximation and barrier penetration is presented. The model is applied to 23Na+208Pb. The ...

HERC 1 Ubiquitin Ligase Mutation Affects Neocortical, CA3 Hippocampal and Spinal Cord Projection Neurons: An Ultrastructural Study
(Frontiers Media, 2016)
The spontaneous mutation tambaleante is caused by the Gly483Glu substitution in the highly conserved N terminal RCC1-like domain of the HERC1 protein, which leads to the increase of mutated protein levels responsible for ...

Null controllability of the semilinear heat equation
(EDP Sciences, 1997-04)
This paper is concerned with the null controllability of systems governed by semilinear parabolic equations. The control is exerted either on a small subdomain or on a portion of the boundary. We prove that the system is ...

Microheterogeneous catalysis
(MDPI, 2010)
The catalytic effect of micelles, polymers (such as DNA, polypeptides) and nanoparticles, saturable receptors (cyclodextrins and calixarenes) and more complex systems (mixing some of the above mentioned catalysts) have ...

Strongly compact algebras
(Real Academia de Ciencias Exactas, Fisicas y Naturales, 2006)
An algebra of bounded linear operators on a Hilbert space is said to be strongly compact if its unit ball is relatively compact in the strong operator topology. A bounded linear operator on a Hilbert space is said to be ...

Low-frequency excitations in a molecular glass: Single-particle dynamics
(American Institute of Physics Publising LLC, 1992)
The low-frequency dynamics of a molecular glass former has been investigated by means of inelastic neutron scattering from a mostly incoherent sample as well as by computer molecular-dynamics simulation. The mode assignments ...

Relativistic current densities for bound spin-orbit partners and the longitudinal-transverse response in (e,ép) processes
(Elsevier, 1998-11-23)
Scalar, baryon and vector-current densities in coordinate and momentum space are calculated within a relativistic mean-field model. The role of the low components of the bound nucleon wave function is investigated in detail ...
