Due to the progressive lowering of the age of peak performance among swimmers, it became important to better understand the factors influencing performance in prepuberal boys and girls. Aim of this study is to compare two different racial/ethnic groups of…

Recording noise gratings with single-beam exposures in bleached silver halide emulsions is used as a holographic spectroscopy technique in order to analyse and optimize photochemical processing. In particular, rehalogenating type bleachings are analysed by measuring the transmittance through the recorded…

We propose a two step method which enables us to obtain transmission Holographic Optical Elements of high diffraction efficiency as well as a good signal-to-noise relation. By means of a device using partially coherent light, a master Holographic Optical Element…

Nanostructured cobalt oxide (Co3O4) electrodes were prepared by two different methods. The first one involved the synthesis of Co3O4 nanoparticles through a nanocasting route using commercial silica gel as a sacrificial template, and in the second one, the Co3O4 electrodes…

Theodore Motzkin proved, in 1936, that any polyhedral convex set can be expressed as the (Minkowski) sum of a polytope and a polyhedral convex cone. This paper provides five characterizations of the larger class of closed convex sets in finite…

Realistic mathematical models are of great importance for studying the optical performance of the human eye. Light propagation algorithms provide robust methods to calculate field distributions inside a homogeneous medium, and thus they can be applied to the study of…

Background: Education is a basic prerequisite for d/Deaf people’s health. Deaf education varies considerably from country to country and we still know very little about the reasons for such variation. Objective: To identify international megatrends that influence the current Deaf…

The purpose of this paper is to provide a comprehensive review of Body Percussion from all areas, focusing on existing academic literature and the contribution of different authors. Existing ethnographic publications are reviewed, as are the links with traditional dances,…

The robotics is one of the most active areas. We also need to join a large number of disciplines to create robots. With these premises, one problem is the management of information from multiple heterogeneous sources. Each component, hardware or…
