Although a priori thinking would suggest that a low intensity crop is environmentally favourable, this assumption ignores the effect of reduced productivity which could simply lead to pollution shifting to other places. A life cycle assessment of the wheat ...
The ab initio mol. dynamics method is extended to treat exchange of electrons between mols. and a reservoir at fixed chem. potential. The method is based on a rigorously grand-canonical d. functional approach using sep. potential energy surfaces for each o ...
The potential of the vertebrate limb as a model system to study developmental mechanisms is particularly well illustrated by the analysis of the Hox gene network. These genes are probably involved in the establishment of patterns encoding positional inform ...
A series of ether-derivatized imidazolium halides have been prepd. and characterized. Contrary to literature reports, they are all cryst. solids and have m.ps. well above room temp. (50-100 °C). Single crystals of the imidazolium salts, obtained in situ by ...
In this article, we describe the application of an enhanced genetic algorithm to the problem of hardware-software codesign. Starting from a source code written in a high-level language our algorithm determines, using a dynamically-weighted fitness function ...
In this paper, we define the concept of digital actors and show their importance in the future interactive digital television and multimedia. We discuss the applications of these digital actors in the new multimedia services especially for training and edu ...
