Influencia de la adición del filler calizo sobre el fraguado del cemento
The present paper deals about the infuence that addition of calcareous "filler" has on the set of portland cement which rates are from 0 up to 50% of filler.

Synthesis of Conducting Polymer Composite Fibers in Electrochemical Flow Cells
A one‐step electrochemical synthesis of polymer and composite polymer fibers of macroscopic dimensions (>10 cm length and 0.2 mm diam) is reported. Poly(3‐methylthiophene) and polypyrrole fibers are grown from the tip of a Pt microelectrode by oxidation of 3‐methylthiophene and pyrrole, respectively, in a capillary fl…
Electrochemistry of Conductive Polymers: XIV . In Situ Spectroelectrochemical and Kinetic Studies on Poly(3‐Methylthiophene) Growth
The growth mechanism of poly(3‐methylthiophene) has been studied employing in situ spectroelectrochemical and kinetic measurements. Results indicate that: ( i ) the polymer film grows only when 3‐methylthiophene is oxidized, suggesting that the radical‐radical coupling reaction is important for the polymer growth; ( i…

Dynamic light scattering with a CCD camera
We have successfully implemented a method to measure intensity autocorrelation functions with a CCD camera and a fast computer. We report light scattering experiments on solutions of diffusing latex spheres in glycerol and compare our results to those obtained with a conventional hardwired electronic correlator. Avera…
Continuous drift correction and separate identification of ferrimagnetic and paramagnetic contributions in thermomagnetic runs
The principle of a Curie balance was changed by using a sinusoidally cycling applied magnetic field instead of a fixed applied field. This was done with a horizontal translation type Curie balance. By cycling between field values Bmin and Bmax, the output signal is amenable to Fourier analysis. Partial Fourier analysi…
Magnetic phase transitions ofMnWO4studied by the use of neutron diffraction
Neutron-powder-diffraction data, collected with the D1B diffractometer, and single-crystal data, collected with the D10 four-circle diffractometer, both at the Institut Max von Laue--Paul Langevin, Grenoble, and single-crystal data, collected with the DN4 four-circle diffractometer at the Centre d'Etudes Nucl\'eaires…
Higher-order response theory based on the quasienergy derivatives: The derivation of the frequency-dependent polarizabilities and hyperpolarizabilities
The higher-order response theory to derive frequency-dependent polarizabilities and hyperpolarizabilities is examined by means of the differentiation of the ‘‘quasienergy’’ with respect to the strengths of the time-dependent external field, which is referred to as the quasienergy derivative (QED) method. This method i…
