(1970)The two major methionyl-tRNA species from wheat embryos and E. coli have been studied as regards their capacity to form a ternary complex with GTP and the ribosomal binding enzyme from both sources. Methionyl-tRNA1 from ...
-
(1991)In addition to known compounds, a new furoeremophilane and two pairs of epimeric acetals with an eremophilane skeleton have been isolated from Senecio pachyphyllos. The structures were elucidated by high field 1H NMR ...
-
(American Chemical Society, 1998)The relationship between global softness and static dipole polarizability is explored from the analogy of the spherical averages defined within density functional theory. A cubic relationship is obtained that is consistent ...
-
(1981)The exact ground state of a four-atom system described by the generalized form of the Hubbard Hamiltonian is obtained. Next, the solution is used to extract relevant physical information on the dynamics of the cluster ...
-
(Escuela de Ciencias del Mar, 2003)Upwelling shadows are high temperature regions within coastal upwelling systems. In this article its dynamics is described at Mejillones Bay, in the northern Chilean coast, using satellite images and in situ current data. ...
-
(1969)THE effect of temperature on the resting potential has been studied in a number of different preparations1-3, and has attracted considerable theoretical interest. In the axons of the squid Loligo forbesi, the resting ...
-
(1970)The adsorption of bovine serum albumin (BSA) at an air/water interface was shown to be reversible and the equilibrium adsorption isotherm measured for concentrations between 0.001% and 10.0%. The desorption of BSA into a ...
-
(1992)A model correlation factor is used to derive an exchange-correlation functional. The factor satisfies the cusp condition and the normalization of the second-order density matrix. No use is made of the homogeneous-electron-density ...
-
(2008)Let G be a finite group, Λ an absolutely irreducible ℤ[G]-module and w a weight of Λ. To any Galois covering with group G we associate two correspondences, the Schur and the Kanev correspondence. We work out their relation ...
-
(1988)Thirteen sterols were identified from the marine sponge Tedania excavata. Among them, Δ5-derivatives were the principal components with minor amounts of stanols. The presence of a Δ5,7-derivative and a 3β-hydroxy-Δ5-7-keto ...

(1990)The aerial parts of Bahia ambrosioides afforded several germacranolides and heliangolides one of which has not been reported previously. Furthermore, in addition to widespread compounds, four 3-hydroxyumbelliferone derivatives ...

-
(Springer-Verlag, 1993)The potential curve of the ground state dissociation of Li-F in water has been studied by a combination of a standard ab initio Hartree-Fock procedure and a perturbative reaction field approach. The electrostatic solute-solvent ...
-
(1988)The influence of the donor-acceptor properties of several solvents on the Cr(CO)5 group in the solid [Cr(CO)5·solvent] complexes has been examined by spectroscopic methods. Relationships were found between the acceptor ...
-
(1992)Using dichotomy conditions, we obtain asymptotic formulae for the solutions of perturbed linear second order difference equations. © 1992.
-
(1992)For perturbations conditionally integrable. Levinson's theorems are obtained and applied to almost constant systems. © 1992.
-
(Kluwer Academic Publishers, 1977)The dietary composition of the antarctic fish Notothenia gibberifrons Lönnberg in a depth gradient was studied, from sea level until 200 meters in South Bay, Doumer Island, West Antarctic. The diet of this species varied ...
