The different demands of competition coupled with the morphological and physiological characteristics of cyclists have led to the appearance of cycling specialities. The aims of this study were to determine the differences in the anthropometric and physiological features in road…

STUDY OBJECTIVE: The aim was to investigate the association between mothers' occupational exposure during pregnancy and the incidence of acute lymphoblastic leukaemia in children. DESIGN: The study was a case-control investigation. A face to face interview was used to assess…

Mi intención es explicar cómo el texto crea significado con estructuras de sintaxis marcadas; pretendo observar el potencial de la lengua por medio del análisis desde una perspectiva funcional de dos estructuras anómalas en la lengua inglesa como son la…

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 evenly convex hull of a given set is the intersection of all the open halfspaces
which contain such set (hence the convex hull is contained in the evenly convex hull). This paper
deals with finite dimensional linear systems containing…

The methods of differential geometry are used with the assumption that rays of light follow geodesic trajectories in a space whose metric is determined by the refraction index. Keeping this in mind, we show that these hypotheses are equivalent to…

The harmonic balance method is used to construct approximate frequency–amplitude relations and periodic solutions to the relativistic oscillator. By combining linearization of the governing equation with the harmonic balance method, we construct analytical approximations to the oscillation frequencies and periodic…

Our intention in this paper is to shortly address some of the basic categories that determine the paradigm of sport culture as we know it. We do believe that by understanding these basic categories the changes of prevailing sport paradigm,…

The current study attempts to describe the free time of City of Havana (Cuba) population older than 15 years, distinguishing between word days, weekends and vacation and holiday periods, determining the population's socio-demographic profile. The object population of study numbers…
