Nowadays, the material disassembly is an important issue for the industry. This paper presents an algorithm to sequence the task to be performed in the disassembly of a specific material from a product or to separate all the materials of…

In order to determine the characteristics of papers published in the rheumatological literature, we have conducted a survey of the seven leading rheumatological journals published in 1987; 1107 original papers have been reviewed and classified according to study design, statistical…

An approximate scheme for obtaining the period of a simple pendulum for large-amplitude oscillations is analysed and discussed. When students express the exact frequency or the period of a simple pendulum as a function of the oscillation amplitude, and they…

The electrochemical oxidation of serine and alanine was performed at Pt(100) and Pt(110) electrodes and analysed by means of FTIR spectroscopy and cyclic voltammetry. The open circuit adsorption of both amino acids was also investigated. The oxidation of serine gives…

Cyclic voltammetry (CV) and Fourier transform infrared reflection-absorption spectroscopy (FT-IRRAS) have been combined to analyse the oxidation of methylamine and ethylamine on platinum single crystal electrodes in an acidic medium. The oxidation of both amines on Pt(hkl) electrodes gives rise…

Objective: Although the relationship between area socioeconomic environment and obesity is known, previous research has measured area socioeconomic environment at only one point in time. This study evaluates the relationship of cumulative area-based adverse socioeconomic environment with body mass index…

Athletic taping is an adjunct mechanism adopted as a preventive measure of injuries or post-injury rehabilitation and prophylaxis. The tape is chosen properly so that it could be able to properly strap the body parts, e.g., ankle, wrist, finger, etc.…

The purpose of this study is to determine whether Spanish adolescents studied attain a level of physical activity, which complies with current guidelines for this age group. 90 adolescents (54 girls and 36 boys) aged 12 to 14 took part…

Applying the method of main components by Hotelling and the method of rotation of the main components, i.e. Varimax rotations by Keiser, the latent structure of basketball efficiency was established. It was based on the fourteen manifest indicators of efficiency.…

The electrodeposition of lead dioxide from lead(II) nitrate in an acid medium has
been used as a test reaction to study the effects of an ultrasound field. The different behaviours found between platinum and glassy carbon electrodes have been compared…
