The effect of adding Sn to Pt/CeO2–Al2O3 and Pt/Al2O3 catalysts was studied with X-ray photoelectron spectroscopy (XPS), 119Sn Mössbauer
spectroscopy, and adsorption microcalorimetry of CO at room temperature. Catalysts were reduced in situ at 473 (non-SMSI state) and 773 K

The sea level variation (SLVtotal) is the sum of two major contributions: steric and mass-induced. The steric SLVsteric is that resulting from the thermal and salinity changes in a given water column. It only involves volume change, hence has no…

A new analytical approximate expression for the period of the simple pendulum is obtained by using a heuristic but pedagogical derivation. This formula depends on two parameters obtained by comparing term-by-term the power-series expansions of the approximate and exact expressions…

This paper addresses the influence of information technology in human resources management (HRM) and specifically on training policy through the experience of a Spanish telecommunications firm, Telefonica. The characteristics of the training model designed by this firm to face new…

Surfaces with radial structure do not fit well to squared detectors or sampling matrices. Cartesian grid sampling provides a different density of nodes in sectors. Zernike polynomials are a complete set of orthogonal polynomials defined on a unit disk often…

Using a dynamic systems perspective, this study investigated whether distance functioned as a control parameter that might alter children’s place kicking patterns. Nineteen children (mean age = 8.1 years) kicked 3 times at each of 5 randomly ordered distances (1.524,…

The purpose of this study was of two-fold, firstly, to evaluate the anthropometric profile of Indian inter-university cricketers and, secondly, to search the correlations among the anthropometric characteristics studied (if any). To serve this purpose, twelve anthropometric characteristics were taken…

Despite its frequent use, there is little understanding of the concept of differential
among upper high school and undergraduate students of physics. As a first step to identify the origin of this situation and to revert it, we have done…

Despite its being the first testimony of Chaucer’s genius, the interest of modern criticism in the Romaunt has mainly focused on the issue of authorship, whereas the efforts to assess this text as a translation have been limited both in…

Phylogenetic relationships within Limonium (Plumbaginaceae) are evaluated using sequence data from three plastid regions (rbcL, the trnL intron, and the trnL-trnF intergenic spacer). Sixty-six species representing the major genera of Staticoideae, including representatives of all sections and genera formerly included…
