En décadas anteriores las emociones estuvieron en gran medida descuidadas en la investigación educativa sobre la enseñanza y los profesores, pero recientemente, se ha prestado más atención al papel de las emociones en la enseñanza y en la vida profesional…

An analytical approximate technique for conservative nonlinear oscillators is proposed. This method is a modification of the generalized harmonic balance method in which analytical approximate solutions have rational form. This approach gives us not only a truly periodic solution but…

Can you imagine a useful task you would like a social robot to perform for you? This paper presents an Internet survey where participants were asked this question to identify applications for social robots. The applications mentioned by the participants…

The second-order harmonic balance method is used to construct three approximate frequency-amplitude relations for a conservative nonlinear singular oscillator in which the restoring force is inversely proportional to the dependent variable. Two procedures are used to solve the nonlinear differential…

Mobile agent technology has traditionally been recognized as a very useful approach to build applications for mobile computing and wireless environments. However, only a few studies report practical experiences with mobile agents in a mobile medium. This leads us to…

Different Pt-based electrocatalysts supported on carbon nanofibers and carbon black (Vulcan XC-72R) have been prepared using a polymermediated synthesis. The electrocatalysts have been characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and cyclic voltammetry. The effect of carbon nanofibers…

This paper deals with the transmission of the main stability properties (lower and
upper semicontinuity in Berge sense, and closedness) from a given closed–convex-valued mapping to
its corresponding relative boundary and extreme point set mappings, and vice versa. The domain

Photographic emulsions are still widely used to record holographic optical elements. In particular, if high diffraction efficiencies are needed, phase volume holograms are preferably recorded on these emulsions. Two particular techniques producing high-quality volume phase holograms are fixation-free rehalogenating bleaching…

The purpose of this study is to determine the influence of the fat mass percentage and age on the mobility of these children. It was used the EK functional motor scale to determine their movement capacity. It was also used…

Purpose – Many international retirement migrants are amenity movers undertaking the first move in the late life course model of migration. The purpose of this paper is to examine second moves within the retirement destination community to test whether the…
