(2008)We give a cohomological characterization of the set of conjugacy classes of finite subgroups of the projective multiplicative group of a finite dimensional algebra that become conjugate to a given group over some finite ...
-
(1972)Absorption spectral, circular dichroic spectral, and viscosity measurements indicate that the compact low-spin conformation characteristic of native cytochrome c is quantitatively recovered from its extended high-spin ...
-
(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 ...
-
(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. ...
-
(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 ...
-
(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 ...
-
(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 ...

(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.
-
(1995)Association constants of alkylpyridine bromide, CnPyB, (methyl, ethyl, propyl, and butyl) to dodecylsulfate micelles has been determined by two methods, ultrafiltration and fluorescence spectroscopy. In the last, the ...
