We tracked the daily movements of three juvenile golden eagles (Aquila chrysaetos) using satellite telemetry. Straight distances covered in an hour and throughout a day were calculated. Daily movements of golden eagles are mostly characterized by short-distance excursions, with 64%…

To analyze the present status of rheumatological research in Spain, three indicators have been evaluated: use of the difference study designs, use of statistical techniques and relevance of the studies. This last point was determined by the comparison of the…

Although there is a general understanding of Montagu’s harrier migration routes and wintering areas, detailed information on the species’ migration is still lacking. However, improvements in satellite tracking technology in recent years have enabled the study of medium-sized species by…

This paper provides information about the magnitude and responses to intimate partner violence against women in Spain.

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…

The electrochemical oxidation of the aniline dimers 2-aminodiphenylamine (2-adpa) and 4-aminodiphenylamine (4-adpa) has been
performed in strongly acidic medium on platinum, graphite, and indium tin oxide electrodes. The resulting films have been
characterized by a number of electrochemical, microscopic, and…

The redox process undergone by the electrochemically synthesized poly(2,2-dithiodianiline), poly(DTDA), has been examined in
acetonitrile-water mixtures by electrochemical and spectroscopic techniques. The spectroscopic properties of this material are equivalent to those exhibited by the chemically synthesized one. The polymeric structure…

Aniline (ANI) and 2-aminoterephthalic acid (2ATA) copolymers, with different compositions, were prepared by
chemical oxidative polymerization varying the feed ratio. The new materials have been characterized by techniques such
as XPS, FTIR, Raman spectroscopies and thermal analysis. It has been…

This paper deals with the non-linear oscillation of a simple pendulum and presents an approach for solving the non-linear differential equation that governs its movement by using the harmonic balance method. With this technique it is possible to easily obtain…

The transitions and reactions involved in the thermal processing of binary mixtures of polyethylene and poly(ethylene-co-vinyl acetate) copolymers with different concentrations of a foaming agent (azodicarbonamide) were studied using differential scanning calorimetry (DSC). The effect of ZnO as a kicker…
