To better understand the nickel-iron electrodeposition process, we have developed one-dimensional numerical model. This model addresses dissociation, diffusion, electromigration, convection and deposition of multiple ion species. The reaction mechanism in this model differs in that Ni2+ and Fe2+ are the electroactive species and NiOH+ and FeOH+ are not involved whatsover. To take account of the...

BACKGROUND The trade of plant roots as traditional medicine is an important source of income for many people around the world. Destructive harvesting practices threaten the existence of some plant species. Harvesters of medicinal roots identify the collected species according to their own folk taxonomies, but once the dried or powdered roots enter the chain of commercialization, accurate identi...

After the conferences in Bonn and Marrakech it is likely that international emission trading will be realized in the near future. Major influences on the permit market are the institutional detail, the participation structure and the treatment of hot air. Different scenarios do not only differ in their implications for the demand and supply of permits and thus the permit price, but also in thei...

This paper investigates the relationship between e-governance and workflow systems which are seen as a tool for improving government processes. The study is based on a real case at the 'Centre Régional d'Investissement' (CRI) of Marrakech, Morocco. The CRI is a government institution entrusted to coordinate various investment projects at the regional level. This paper presents th...

24 European Crystallographic Meeting, ECM24, Marrakech, 2007 Page s126 Acta Cryst. (2007). A63, s126 Escherichia coli beta-galactosidase is known to be active only in the form of tetramers, while the cold-active Arthrobacter sp. C2-2 beta-galactosidase forms compact hexamers with active sites oriented into an internal cavity, connected by three types of channels with exterior solvent. Additiona...
