La gestion terrestre d’une pollution d’origine maritime à l’échelle locale : quelle intégration ?

A l’échelle locale, les acteurs du territoire perçoivent souvent les risques de pollutions côtières par hydrocarbures par une entrée maritime, où les solutions préventives émaneraient des instances juridiques internationales. Néanmoins, dans le cadre de la gestion terrestre d’une pollution, il convient d’intégrer ce risque dans une gestion globale des territoires côtiers, au même titre que d’autres risques (érosion, pollution tellurique…). La gestion des zones côtières doit ainsi avoir pour objectif premier l'amélioration de la coordination de la gestion locale pour une préparation efficace de la lutte à terre. Cela nécessite une intégration qui implique aussi les différents services de l’Etat au niveau national et régional. Dans ce cadre, l’échelle intercommunale semble apparaître privilégiée pour assurer l’interrelation entre l’échelle nationale et internationale et le niveau local.With the local scale, stakeholders often perceive the risks of coastal pollution by hydrocarbons by a maritime entry, where the preventive solutions would emanate from international authorities. Nevertheless, in the scope of coastal management of pollution, it is advisable to integrate this risk in the management of coastal territories, as well as other risks (erosion, telluric pollution…). The aim of integrated coastal zone management is a better coordination of local management for an effective preparation of the terrestrial fight. Intercommunality scale seems to be the best way to ensure the interrelationship between the national and international scale and the communal level

Common Powder Flow Characterization Methods vs. Brookfield\u27s Powder Flow Tester and Shear Cell Technology

Powder flow properties have been characterized for many years using common methods such as Angle of Repose, the Carr Index and Hausner Ratio. These methods have been around for many years and numerous companies, including pharmaceutical companies, manufacturing powders or utilizing gravity feed systems have used these subjective methods to characterize their powders for flow. These common methods in industry will be reviewed and compared to shear cell technology. Shear cell technology gives definitive test results on powder and defines them for flow. A brief discussion of shear cell technology and data results using Mohr circle analysis will be reviewed. Brookfield Engineering’s Powder Flow Tester is one such instrument that utilizes shear cell technology. Brookfield Engineering, in conjunction with the Wolfson Center at the University of Greenwich, developed this automated Powder Flow Tester. This instrument gives defined, repeatable measurements on necessary flow parameters such as Flow Function, Bulk Density, Internal Friction Angle, Arching Dimension and Rat-Hole Diameter. These parameters, and others, will be reviewed and discussed for use in characterizing bulk solids and pharmaceutical powders for flow characteristics. A review of bulk density measurements and how this relates to tablet and capsule manufacturing for the pharmaceutical industry will be discussed

Polymer pinning in a random medium as influence percolation

In this article we discuss a set of geometric ideas which shed some light on the question of directed polymer pinning in the presence of bulk disorder. Differing from standard methods and techniques, we transform the problem to a particular dependent percolative system and relate the pinning transition to a percolation transition

Comparing the effects of the second OPEC oil price shock on income and resource allocation in four oil-poor developing economies: Ivory Coast, Kenya, South Korea, Turkey

The large OPEC-engineered real world oil price increases of the early and late 1970?s have set in train, via a highly integrated international trade and finance system, significant resource transfers from energy-poor to energy-rich countries. In accommodating these resource transfers both energy exporting and importing economies have been confronted with adjustment pressures. In the case of the former group, these adjustment pressures have arisen from the need for these economies to accommodate a favourable shift in their foreign terms of trade, ostensibly by way of a redirection of resources from the international to the domestic account, thus permitting higher real national income. For energy-poor countries however the required adjustment process has much less palatable consequences for economic growth and the real income aspirations of the populations. Our concern in this paper is with a subset of the latter group - the so-called oil-poor developing countries. We focus in considerable detail on four such economies; Kenya, South Korea, Ivory Coast and Turkey. As well as representing various levels of oil 'poorness' these countries exhibit interesting differences in resource endowments, the industrial composition of their gross domestic products, the oil intensity of their industrial production technologies, the skill composition of their labour forces, their openness to world trade and their commodity composition of exports and imports. By means of multisectoral economy-wide models for each of these countries, we quantify the nature and extent of the adjustment pressures imposed on them by what has now become known as the second OPEC oil shock of 1978-80.

On the Existence of a Kazantzis-Kravaris/Luenberger Observer

We state sufficient conditions for the existence, on a given open set, of the extension, to nonlinear systems, of the Luenberger observer as it has been proposed by Kazantzis and Kravaris. We prove it is sufficient to choose the dimension of the system, giving the observer, less than or equal to 2 + twice the dimension of the state to be observed. We show that it is sufficient to know only an approximation of the solution of a PDE, needed for the implementation. We establish a link with high gain observers. Finally we extend our results to systems satisfying an unboundedness observability property
