(Kluwer Academic Publishers-Plenum Publishers, 1988)The olfactory epithelium has the ability to respond to a large number of volatile compounds of small molecular weight. Ultimately, such a property lies on a specialized type of neuron, the olfactory receptor cell. In the ...
-
(1988)The aggregation states of Escherichia coli phosphofructokinase 2 (Pfk-2) and of a mutant enzyme (Pfk-2*) altered in the inhibitory allosteric site for MgATP were measured in the presence and in the absence of substrates ...
-
(1987)The inhibitory effects of guanosine 5'-(ᵧ-fluorotriphosphate) [GTP(ᵧF)] on both the polymerization and the colchicine-dependent GTPase activity of calf brain tubulin have been studied. The results demonstrate that this ...
-
(Kluwer Academic Publishers, 1988)The regeneration of canopy and subeanopy species in a mid-elevation, primary rain forest in the Coastal Range of Isla de Chiloé (42°30′S), in the cold-temperate region of Chile, was studied by comparing seedling and sapling ...
-
(Kluwer Academic Publishers, 1987)Questions of successional pattern and causality have been central concerns in vegetation ecology. In this paper we address the limits of the overextended models of Connell and Slatyer by discussing problems encountered in ...
-
(1987)Stands were dominated by broad-leaved evergreen trees and had in common the presence of several species of Myrtaceous trees in their canopies. Structurally, the forests were dominated by different species, although overall ...
-
(1997)The electronic structure of 1T-TiS2 intercalated with lithium is analysed within a molecular approach that uses a finite-size cluster to represent the solid. Electronic descriptors such as the electronic chemical potential, ...
-
(1987)Pristidactylus volcanensis, a new species from El Volcan, Cordillera de Los Andes, is distinguished by coloration, squamation, measurements, and habitus. -from Authors
-
(1986)The light-activated conductance of Limulus ventral photoreceptors was studied using the patch-clamp technique. Channels (40 pS) were observed whose probability of opening was greatly increased by light. In some cells the ...
-
(1981)The Falicov‐Ramirez‐Kimball model is solved by means of the two‐atom cluster Caron‐Pratt approximation. Metallic and insulating phases according to the value of an order parameter Δ are obtained, and both second‐ and ...
-
(Oxford University Press, 1981)Liolaemus monticola, Müller and Hellmich, is a highly variable, endemic montane species distributed along the temperate Andes in Chile. The subspecies (Müller and Hellmich) karyotypes established from their type localities ...
-
(1975)When hemocyanin is added to a black lipid film, the conductance increases in discrete steps. For negative potentials the single step conductance is constant, but for positive potentials the step conductance appears to ...
-
(1987)The ground state potential energy curves of alkaline-earth monohydride ions have been investigated. A pseudopotential formalism including a corepolarization potential has been used. For the valence correlation energy a ...
-
(Academic Press, 1993)Cobalt and iron can be determined simultaneously by first derivative spectrophotometry. The method does not require simultaneous equations to be resolved and it is based on the separation of the analytes, by liquid-liquid ...
-
(1992)In this work the inverse problem of the variational calculus for systems of differential equations of any order is analyzed. It is shown that, if a Lagrangian exists for a given regular system of differential equations, ...
