Transition metals in form of small supported particles are frequently used in heterogeneous catalytic reactions. One point of actual interest concerns the reactivity of low co-ordination sites characteristic for particle surface. The non continuous epitaxial layers of Pd and Rh were grown on insulator substrates (Al2O3) by molecular beam epitaxy. The reflection high energy electron diffraction ...

BACKGROUND Metered dose inhalers (MDIs) are not easy to use well. Every MDI user receives a manufacturer's patient information leaflet (PIL). However, not everyone is able or willing to read written information. Multimedia offers an alternative method for teaching or reinforcing correct inhaler technique. OBJECTIVE The aim of this study was to compare the effects of brief exposure to the same...

Motivation There is a wide-ranging consensus that co-ordination in development policy needed for aid effectiveness. However, our research reveals number of surprising and significant gaps existing scholarship. Development Palestine has not been researched the phenomenon as “shielding” against domestic contestation remains underexamined. Purpose This article aims to provide better understanding ...

Embedded agents can be used as building blocks or components in the construction of an Intelligent Building (IB). However it remains a great challenge on how to implement this idea in a distributed networking environment. In this paper, we present a co-ordination framework for web-enabled embedded agents to optimize the dynamic allocation of resources and the mobility of services in an intellig...

1. An overview of the problem My aim is to trace the thinking-in-change (Noss & Hoyles, 1996) during the co-ordination of two epistemologically distinct faces of distribution. By co-ordination here, I refer to the connection between a data-centric perspective on distribution, which identifies distribution as an aggregated set of actual outputs, and a modelling perspective on distribution, which...
