Evaluations are provided of 21 descriptors of Posidonia oceanica meadows along the coast of Valencia, Spain, with a view to using these in implementing the European Water Framework Directive (WFD). The descriptors selected are known to respond to a variety…

A Discrete Event System (DES) is a discrete state space dynamic system that evolves in accordance with the instantaneous occurrence, at possibly unkown times, of physical events. Given a DES, its behavior (the sequence of displayed events) may not satisfy…

The aim of this study was to analyse the evolution of critical velocity and critical
stroke rate during 12 weeks of training in age group swimmers. Fourteen age group
male swimmers took part in this investigation. The evaluation took place…

Swimming speed is determined by many factors, including weight preparation of the
swimmer which is one of the most important ones. This power is directly related to the
speed a swimmer can reach in water, that is the value of…

The industrial revolution did not take the environment into
consideration when designing products. However, today
the eco-friendly design of products is a task that gets more
visibility due to the great quantity of industrial waste generated
to finalize the useful…

The electrochemical behaviour of glycine on well-defined Pt(100) and Pt(110) electrodes has been studied in an acid medium by means of cyclic voltammetry and in situ FTIR spectroscopy. The results presented in this paper and those reported previously for the…

The electrochemical oxidation of aniline and p-aminodiphenylamine (ADPA) was carried out in a phosphate buffer solution at pH 5. Cyclic voltammetry and ‘‘in situ’’ FTIR spectroscopy were combined to study the redox behavior of the oxidation products. When ADPA is…

The classical problem of the deflection of a cantilever beam of linear elastic material, under the action of an external vertical concentrated load at the free end, is analysed. We present the differential equation governing the behaviour of this physical…

Bleached holograms are one of the most interesting techniques used to produce phase holograms of high quality on photographic emulsions. Of particular interest is the method of fixation-free rehalogenating bleaching. Using Kogelnik's coupled-wave theory we shall obtain information about the…

Study objectives: (1) To describe the union and life cycle of family rituals, such as specific habits of sharing daily meals, special events or other family activities, and (2) to analyse the relation between the practice of family rituals and…
