Citation analysis and literature trends.

Comments on an article by T. R. Elliott and E. K. Byrd (see record 1987-23075-001), in which the authors conducted a citation analysis of articles in Rehabilitation Psychology, Volumes 27-29. They claimed to identify influential authors and publications useful for training and research in rehabilitation psychology. Their method of citation analysis, however, appears to have distorted their results. Crisp discusses the problems with their methodology, and makes suggestions for using a different citation method, using more than three volumes of the journal, and including other journals in the analysis.

The preparation and properties of coprecipitated Cu–Zr–Y and Cu–Zr–La catalysts used for the steam reforming of methanol

Several samples of exhaust diesel soot are investigated by inverse gas chromatography and linear solvation energy relationship (LSER) modelling according to their soluble organic fraction content and their time of exposure in oxidative conditions. The results demonstrate the evolution of the adsorptive properties of the studied materials towards volatile compounds during the oxidation under NO₂.     

Approximation of certain functions given by integrals with highlyoscillatory integrands

There is often a need to approximate integrals of highly oscillatory functions when studying scattering and diffraction of electromagnetic waves. This paper presents a method of estimating certain types of these integrals by evaluating one interpolating function and performing one or two relatively easy numerical integrations. The method is demonstrated for the case of a Fresnel integral
