The study presented here was carried out to obtain the actual solids flow rate by the combination of electrical resistance tomography and electromagnetic flow meter. A new in-situ measurement method based on measurements of the Electromagnetic Flow Meters (EFM) and Electrical Resistance Tomography (ERT) to study the flow rates of individual phases in a vertical flow was proposed. The study was based on laboratory experiments that were carried out with a 50 mm vertical flow rig for a number of sand concentrations and different mixture velocities. A range of sand slurries with median particle size from 212 mu m to 355 mu m was tested. The solid concentration by volume covered was 5% and 15%, and the corresponding density of 5% was 1078 kg/m(3) and of 15% was 1238 kg/m(3). The flow velocity was between 1.5 m/s and 3.0 m/s. A total of 6 experimental tests were conducted. The equivalent liquid model was adopted to validate in-situ volumetric solids fraction and calculate the slip velocity. The results show that the ERT technique can be used in conjunction with an electromagnetic flow meter as a way of measurement of slurry flow rate in a vertical pipe flow. However it should be emphasized that the EFM results must be treated with reservation when the flow pattern at the EFM mounting position is a non-homogenous flow. The flow rate obtained by the EFM should be corrected considering the slip velocity and the flow pattern.

se ha realizado una producci??n cient??fica de la Praxiolog??a Motriz en el siglo XXI, a partir de los art??culos, libros, tesis, congresos y seminarios de ocho autores referencia, tanto a nivel estatal como mundial dentro de este ??mbito. El objetivo de esta producci??n cient??fica es determinar si todo lo que se ha recopilado y clasificado sobre estos autores pertenece al ??mbito de la Praxiolog??a motriz. La b??squeda de art??culos se ha realizado principalmente, mediante la base de datos Dialnet, mientras que la herramienta para la clasificaci??n y el dise??o de las tablas y cuadros se ha realizado con el sistema inform??tico Microsoft Excel??. Durante este periodo se han publicado un total de 60 art??culos cient??ficos, con un promedio de 7.5 art??culos por autor, cuatro art??culos al a??o y a raz??n de 8.5 art??culos por apartado. Estos datos indican que la producci??n cient??fica es pobre ya que tan solo tres autores son los que centran la mayor??a de publicaciones y tres los apartados con la mayor??a de textos. Se ha enfatizado la necesidad de tener facilidad para una informaci??n mayor sobre art??culos, seminarios y congresos para tener mayor volumen de art??culos dado que 43 son los art??culos que se han quedado sin clasificar.
