Influencia de la deshidrataci??n en la condici??n f??sica espec??fica del k??rate (modalidad de kumite)

Se presenta un trabajo de investigaci??n sobre la deshidrataci??n y sus efectos sobre el organismo en el rendimiento deportivo de manera espec??fica. El objetivo del estudio es conocer la influencia o grado de afecci??n de la deshidrataci??n (2% inducida mediante sauna y restricci??n de l??quidos) en la condici??n f??sica del k??rate deportivo (en la modalidad de kumite o combate). La aplicaci??n de este estudio al marco escolar se centra b??sicamente en contenidos que pueden ser impartidos en la asignatura de Acondicionamiento F??sico de 2?? de Bachillerato, en alto rendimiento deportivo, prescrito en el curr??culo oficial de esta materia.

Comunicaci??n presentada en las Jornadas sobre Investigaci??n e Innovaci??n en la Educaci??n F??sica escolar celebradas en el CEP de La Laguna, del 2 al 5 de junio de 2010

Enhancement of oxidation rate of a-Si nanoparticles during dehydrogenation

Oxidation of amorphous silicon (a-Si) nanoparticles grown by plasma-enhanced chemical vapor deposition were investigated. Their hydrogen content has a great influence on the oxidation rate at low temperature. When the mass gain is recorded during a heating ramp in dry air, an oxidation process at low temperature is identified with an onset around 250°C. This temperature onset is similar to that of hydrogen desorption. It is shown that the oxygen uptake during this process almost equals the number of hydrogen atoms present in the nanoparticles. To explain this correlation, we propose that oxidation at low temperature is triggered by the process of hydrogen desorption

The effect of click rate in variance ratios for auditory brainstem responses in normal hearing ears

This paper investigates the effect of varying presentation (click) rates in variance ratios for auditory brainstem responses (ABR).

Average annual reading growth rate progress of children who are deaf, use a cochlear implant and attend an auditory-oral school

Reading growth rate averages were established for children who are deaf, have a unilateral cochlear implant and attend an auditory-oral school.

Differential sensitivity to tonal frequency and to the rate of modulation of broad-band noise by hearing-impaired listeners

This dissertation examined whether a hearing impairment of the auditory end-organ has the same or a differential effect on the place and periodicity processes. Differential sensitivities for four normally hearing listeners and for both ears of five patients with unilateral Meniere’s disease were measured for tonal frequency and rate of sinusoidally amplitude-modulated noise at common frequencies and rates of the stimulus.
