This article aims to present the current knowledge on physiological requirements in Olympic distance and Ironman triathlon. Showing the data available from a “traditional point of view” (aerobic power, anaerobic threshold, heart rate, running economy) and from a “contemporary” point…

The paper draws on in-depth qualitative. comments from student evaluation of an e-learning module on an MSc in Information Technologies and Management, to develop a picture of their perspective on the experience. Questionnaires that yielded some basic quantitative data and…

Magnetic Resonance Imaging (MRI) is an important diagnostic imaging tool that has
seen rapid expansion in recent years with a commensurate increase in the number of
radiographers undertaking MRI scans. This imaging modality is a complex one and the strong

To demonstrate that parsimony analysis of endemicity (PAE) can be a method implementing the panbiogeographic approach, we analyzed two data matrices of 40/38 biogeographic provinces x 148 plant species from the Caribbean subregion of the Neotropical region, one where taxa…

This paper provides evidence on the incidence of poverty among the elderly in Latin America and the Caribbean, based on household survey microdata from 20 countries. The situation of older people is characterized in terms of income, employment, education, health…

In the midst of a serious macroeconomic crisis Argentina implemented a large social program -the Programa Jefes de Hogar (PJH)- that provides cash transfers to unemployed household heads meeting certain criteria. In practice, giving the difficulties in monitoring informal jobs,…

Real-time holographic interferometry has been used to visualize the evolution of the polarization layer during dead-end ultrafiltration of PEG-10000. Several experiments at a constant pressure of 1 bar and varying the feed concentration of PEG-10000 (5–12.5 kg/m3) have been carried…

A statistical model is used to study the formation of noise gratings in holograms and the mechanism that causes radiation scattering in them. The theoretical model presented describes noise scattering in terms of diffraction due to the high number of…
