Efectos de la modulación colinérgica y la administración de R-(+)-8-OH-DPAT sobre la evitación inhibitoria a lo largo del ciclo vital en ratones

2015

Las sustancias que actúan modulando los sistemas de neurotrasmisión colinérgico y serotoninérgico, como algunos antidepresivos, han demostrado en estudios previos un efecto deteriorante o facilitador en el aprendizaje y memoria de la tarea de evitación inhibitoria en roedores. Este trabajo tuvo como objetivo el investigar el papel que los sistemas de neurotrasmisión colinérgico y serotoninérgico a través de la administración de diferentes sustancias juegan en la consolidación del aprendizaje de evitación inhibitoria a lo largo de tres etapas del ciclo vital de ratones machos y hembras. Para ello se emplearon fármacos más específicos que interfieren en estos dos sistemas para analizar el efe…

Dado de hueso cargado. Ilegalidad y aceptación social

2017

Los juegos de azar han acompañado a la humanidad desde épocas muy tempranas, y los dados no han sido la excepción. En este artículo hablaremos del hallazgo hecho en una exploración arqueológica, de un dado de hueso, ilegalmente cargado; y también revisaremos un poco de historia sobre las prohibiciones de los juegos de azar. Posteriormente, juntando experimentación y matemáticas, fabricaremos un nuevo dado de hueso cargado, y mediante la probabilidad descubriremos qué sucede al usarlo.

Testing the Dispersion of Nanoparticles in a Nanocomposite with an Ultra-Low Fill Content Using a Novel Non-Destructive Evaluation Technique

2022

A non-destructive evaluation (NDE) technique capable of testing the dispersion of nanoparticles in a nanocomposite would be of great use to the industry to check the quality of the products made and to ensure compliance with their specifications. Very few NDE techniques found in the literature can evaluate the level of dispersion of the nanoparticles in the whole nanocomposite. Here, a recently developed NDE technique based on pulsed phase thermography (PPT) in transmission mode was used to assess the particle dispersion in ultra-low, less than 0.05 wt%, Ag enriched polymeric based nanocomposite manufactured with an innovative nano-coating fragmentation technique. The phasegrams obtained wi…

Scanning Tunneling Spectroscope Use in Electrocatalysis Testing

2010

Published version of an article from the journal: Materials (1996-1944). Also available from publisher: http://dx.doi.org/10.3390/ma3063675 The relationship between the electrocatalytic properties of an electrode and its ability to transfer electrons between the electrode and a metallic tip in a scanning tunneling microscope (STM) is investigated. The alkaline oxygen evolution reaction (OER) was used as a test reaction with four different metallic glasses, Ni78Si8B14, Ni70Mo20Si5B5, Ni58Co20Si10B12, and Ni25Co50Si15B10, as electrodes. The electrocatalytic properties of the electrodes were determined. The electrode surfaces were then investigated with an STM. A clear relationship between the…
