This paper examines the recent siting of foreign-owned corporate technological development in European regions. The data used are patents granted in the US to the world's largest firms in the period 1987-‘95. According with the literature on knowledge creation in MNCs, we find that location of foreign-owned research tends to agglomerate, depending positively upon the potential for intraand inte...

In this study a three-phase homogeneous model was developed to simulate the performance of the molten carbonate fuel cell ~MCFC! cathode. The homogeneous model is based on volume averaging of different variables in the three phases over a small volume element. This approach can be used to model porous electrodes as it represents the real system much better than the conventional agglomerate mode...

BACKGROUND The likelihood of a Randall's plug composed of calcium oxalate monohydrate (COM) forming by the free particle mechanism in a model of kidney with a structure recently described by Robertson was examined at the most favourable conditions for the considered mechanism. METHODS The Robertson model of the kidney is used in the following development. The classical theory of crystallizati...

Abstract The contribution of soot aerosols to radiative forcing and climate change depends on their optical properties. Since these are agglomerates composed quasi-spherical primary particles (usually small with respect the radiation wavelength), properties can be calculated following Rayleigh-Debye-Gans approximation, which considers as independent absorbers scatterers, corrections made accoun...

This paper develops a simple model of spatial sorting where the least productive entrepreneurs are drawn to large core region. is an unusual feature. The literature on typically shows how most individuals and firms agglomerate core. However, our consistent with empirical evidence that reveals agglomerations also attract low skilled.

In order to reduce energy consumption in the blast furnace ironmaking process, it is important promote not only rapid reduction of ore but also carburization and melting metallic iron. this study, use carbon-iron composite which an agglomerate fine iron carbonaceous material was focused on, effects type slag content on were examined.
