The present work reports our attempt in automating the translation of English noun phrase (NP) into Arabic. Translating NP is a very important task toward sentence translation since NPs form the majority of textual content of the scientific and technical documents. The system is implemented in Prolog and the parser is written in DCG formalism. The paper also describes our experience with the developed MT system and reports results of its application on real titles of theses from the computer science domain.

The use of Ni as a catalyst for the electro-oxidation of methanol in alkaline medium was studied by cyclic voltammetry. It was found that only Ni dispersed on graphite shows a catalytic activity towards methanol oxidation but massive Ni does not. Ni was dispersed on graphite by the electro-deposition from acidic NiSO4 solution using potentiostatic and galvanostatic techniques. The catalytic activity of the C/Ni electrodes towards methanol oxidation was found to vary with the amount of electro-deposited Ni. The dependence of the oxidation current on methanol concentration and scan rate was discussed. It was concluded from the electro-chemical measurements and SEM analysis that methanol oxidation starts as Ni-oxide is formed on the electrode surface.

Nickel and ruthenium dispersed on graphite electrode showed a catalytic activity towards methanol oxidation in KOH solution. Various modified graphite electrodes of different Ni–Ru ratios were prepared by the electro-deposition of Ni and Ru from their salt solutions by changing the relative concentration of each metal ion in the deposition bath. Results of the electrochemical measurements revealed that simultaneous deposition of the binary metals is the best method to prepare the catalyst. The relative distribution of Ni–Ru deposits on the graphite electrode depends on the method of deposition as shown by optical microscope analysis. The catalytic activity of the bimetallic catalyst C/(Ni–Ru) towards methanol oxidation was found to vary with the amount of electrodeposited Ni and Ru. However, the catalytic activity increases with increasing the Ni content relative to Ru in the electrode. The dependence of the oxidation current on methanol concentration and the upper- and lower-potential limits was discussed. It was concluded from the electrochemical measurements that methanol oxidation begins at the potential value of NiOOH production with the formation of intermediate products. The presence of perruthenate species on the electrode surface is responsible for the complete oxidation of the intermediate species.
