Glutathione biosynthesis in Arabidopsis trichome cells
(National Academy of Sciences, 2000)
In Arabidopsis thaliana, trichome cells are specialized unicellular structures with uncertain functions. Based on earlier observations that one of the genes involved in cysteine biosynthesis (Atcys-3A) is highly expressed ...

Pre-requisitos ontogenéticos para la emergencia de relaciones simétricas
(Asociación de Análisis del Comportamiento (AAC), 2001)
Al trabajar con humanos usando discriminaciones condicionales se obtiene sistemáticamente la formación de clases de equivalencia. Sin embargo, no existen demostraciones inequí- vocas del desarrollo de este tipo de ...

Late Holocene evolution of the southwestern Doñana National Park (Guadalquivir Estuary, SW Spain): A multivariate approach
(Elsevier, 2004)
Four phases are distinguished in the Late Holocene evolution of the southwestern Doñana National Park (SW Spain), based on a multidisciplinary analysis of the sediments present in drill cores. In the oldest phase (>2400-2500 ...

Experiments on pumping of liquids using arrays of microelectrodes subjected to travelling wave potentials
(IOP Publishing Ltd., 2008)
Net fluid flow of electrolytes driven on an array of microelectrodes subjected to a travelling-wave potential is presented. Two sizes of platinum microelectrodes have been studied. In both arrays, at low voltages the liquid ...

Boundary conditions and normal state for a vibrated granular fluid
(American Physical Society, 2000)
The steady state of a fluidized granular system confined between a vibrating wall and a reflecting one is analyzed in detail. The relationship between the velocity of the wall and the hydrodynamic profiles is established. ...

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 ...

Remarks on the determination of the Landau gauge OPE for the asymmetric three gluon vertex
(American Physical Society, 2001-12-01)
We compute a compact operator product expansion (OPE) formula describing power corrections to the perturbative expression for the asymmetric momentum subtraction–(MOM̃−) renormalized running coupling constant up to the ...

Intrinsic state for an extended version of the interacting boson model
(American Physical Society, 2000-03-01)
An intrinsic-state formalism for the interacting boson model IBM-4 is presented. A basis of deformed bosons is introduced which allows the construction of a general trial wave function that has Wigner’s spin-isospin SU(4) ...

Structure of the fixed point set and common fixed points of asymptotically nonexpansive mappings
(American Mathematical Society, 2001)
Let X be a Banach space, C a weakly compact convex subset of X and T : C → C an asymptotically nonexpansive mapping. Under the usual assumptions on X which assure the existence of fixed point for T, we prove that the set ...

Increased Cysteine Availability is Essential for Cadmium Tolerance and Accumulation in Arabidopsis Thaliana
(Wiley Open Access, 2004)
Employing genetic transformation using an Atcys-3A cDNA construct expressing the cytosolic O-acetylserine(thiol)lyase (OASTL), we obtained two Arabidopsis lines with different capabilities for supplying cysteine under metal ...
