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…

In this letter, a method for the improved consideration of propagation losses in metallic waveguide structures is presented. The method relies on the perturbation of the boundary conditions on the metallic walls of the waveguides. Following this advanced technique, we…

Phase equilibrium data regression is an unavoidable task necessary to obtain the appropriate values for any model to be used in separation equipment design for chemical process simulation and optimization. The accuracy of this process depends on different factors such…

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…

At this paper we present an original questionnaire which aims to study the perception of linguistic insecurity (IL). The questionnaire is designed as an instrument for analysis of IL in the context of quantitative research., En aquest treball presentem un…

In order to keep the life and works of J.A. Samaranch alive in the memory of the Olympic section of the Journal of Human Sport and Exercise, the Editorial Committee has decided to recover a previously unpublished interview from the…

Introduction: The increased number of articles published in nutrition is a reflection of the relevance to scientific community. The characteristics and quality of nutritional studies determine whether readers can obtain valid conclusions from them, as well as their usefulness for…

Spontaneous eye blinking is a complex process, which implies the joint actions of the eyelid muscles and the eye globe. These actions provoke the eyelid closure and simultaneous eye retraction into the orbit. Recently, the authors presented a non-invasive technique…

What is the relationship between the awareness of linguistic prestige and the security or insecurity in the use of minoritised languages? Is formal linguistic insecurity (as initially described by Labov) the same as the speakers’ perception of linguistic insecurity? Which…
