Preliminary data on horse mackerel (Trachurus spp) landings from Mauritanian waters

European fishery off Mauritania (one of the most productive and most intensively exploited regions in the world) targeted to small pelagic fish accounts for 30% of the total catches in the area. The Instituto Español de Oceanografía (IEO), through its Centro Oceanográfico de Canarias, follows up the activity of these vessels that land at Spanish port (Las Palmas de Gran Canaria, Spain), under the European Project Data Collection (Regulation (EC) 1543/2000). One of the target groups in this fishery is Trachurus spp, commercially named “JAX”. During 2008 and 2009, several samples of this group from these landings were analysed, and Caranx rhonchus was the second species of importance. The mixture of these species in the landings of this UE fleet should be determined to improve the data provided to the international Working Groups responsible for assessment of those resources.

Red de investigación en Visión Artificial y Robótica. Establecimiento de contenidos e implantación y seguimiento del plan de evaluación

Se presenta en esta memoria el trabajo desarrollado durante el curso 2013/14 por los componentes de la “Red de investigación en Visión Artificial y Robótica. Establecimiento de contenidos e implantación y seguimiento del plan de evaluación”. Código de Red ICE 3031. Este ha sido el primer curso en el que se imparte la asignatura a estudio y nuestros esfuerzos han estado orientados tanto a la valoración de los materiales elaborados en los años precedentes como al seguimiento y ponderación del sistema de evaluación propuesto para la asignatura de Visión Artificial y Robótica y que consiste en la evaluación continua de trabajos desarrollados por los estudiantes a lo largo de todo el cuatrimestre. Además, estos trabajos han de ser expuestos oralmente en el aula. Para ello, el alumno ha de desarrollar también las transparencias que le sirvan para apoyar su presentación.

Diamond Surface Modification to Enhance Interfacial Thermal Conductivity in Al/Diamond Composites

Diamond/metal composites are very attractive materials for electronics because their excellent thermal properties make them suitable for use as heat sink elements in multifunctional electronic packaging systems. To enlarge the potential applications of these composites, current efforts are mainly focused on investigating different ways to improve the contact between metal and diamond. In the present work, a theoretical study has been carried out to determine the differences between the interfacial thermal conductance of aluminum/diamond and aluminum/graphite interfaces. Additionally, diamond particles were surface modified with oxygen to observe how it affects the quality of the diamond surface. The characterization of the surface of diamonds has been performed using different surface analysis techniques, especially x-ray photoelectron spectroscopy and temperature-programmed desorption.

Reduction of 1,2-dicarbonyl compounds and of their N-phenylimine derivatives by sodium cyanide under aprotic conditions

Some aromatic 1,2-dicarbonyl compounds, i.e. 9,10-phenanthrenequinone, acenaphthenequinone and benzil, and their corresponding N-phenyl monoimines, have been reduced, using dry acetonitrile as the solvent, in the presence of sodium cyanide as a reducing agent. Comparative potentiostatic preparative-scale electrolysis is described.
