EARTH MODELS WITH CHEMICALLY HOMOGENEOUS CORES

Compressible viscoelasticity: stability of solutions for homogeneous plane-Earth models

Characteristics of chemically reacting compressible homogeneous turbulence

Direct numerical simulations ~DNS! are conducted to study the turbulence-chemical reaction interactions in homogeneous decaying compressible fluid flows. The reaction is of a single-step irreversible Arrhenius type. The results indicate that the heat of reaction has a noticeable influence on the solenoidal and the dilatational turbulent motions. The effect of reaction on the solenoidal velocity...

Rare earth cryptates and homogeneous fluoroimmunoassays with human sera.

The rare earth cryptates are used as long-lived fluorescent labels. They are formed by inclusion of a europium ion in the intramolecular cavity of a macropolycyclic ligand containing bipyridine groups as light absorbers. The use of fluoride ions in the measuring medium allows a total shielding of the label fluorescence. Here, I have established the conditions under which the signal of these cry...

Estimation of pore water pressure in the body of earth dams during construction with intelligent models

One of the basic measures in managing the stability of earth dams is to accurately estimate the amount of pore water pressure in the body of the dam during and after its construction. In this study, three different models of artificial neural network (ANN), adaptive neural-fuzzy inference system (ANFIS) and gene expression programming (GEP) to estimate the pore water pressure in the body of Kab...

Tame Theories with Hyperarithmetic Homogeneous Models

A tame theory is a decidable first-order theory with only countably many countable models, and all complete types recursive. It is shown here that the recursive complexity of countable homogeneous models of tame theories is unbounded in the hyperarithmetic hierarchy. Recursive model theory considers model-theoretic objects and constructions from the point of view of recursion-theoretic complexi...
