This current article shows a procedure to improve wind turbines for kinetic energy conversion in mechanics using a new concentrating design based on moist air phase change. This concentrator presents special interest in the European Atlantic Coast because its weather is mild with a high relative humidity and its winds represent low values for wind turbines(More)
The incorporation of heteroduplex analysis into conventional strategies for the study of polymorphisms at microsatellite loci has allowed us to obtain information useful in determining genetic diversity and relationships among organisms. We have chosen, as a model for the testing of this strategy, several Solanum tuberosum varieties cultivated on Tenerife(More)
In this paper we present the predicted performance of the TerraSAR-X for meteorological purposes. Principally, the study focuses on the possibility of measuring rain over ocean and forest. Regarding the acquisition geometry, we investigate the rain volume and voxel resolution, the signal-to-noise ratio and the signal-to-clutter ratio. The clutter(More)
Galician climate conditions show the right ambience for wind turbines power generation during the winter and spring season whereas in the summer, the low wind velocity and the moist air density reduce the possibility of energy conversion. To solve this problem, low wind speed wind turbines were assessed during the last few years. In recent papers, some(More)
Galician climate conditions present the right ambience for wind turbines power generators during winter and spring seasons even though its climate change may affect wind velocity and moist air density by reducing the energy conversion. Planet Global Heating was analyzed for Galician climate showing a rise in the average temperature in each season. In this(More)
In order to ensure flexibility and rapid new product development, the mold industry made use of soft materials for cavity inserts in injection molds. However, materials of this kind are prone to wear. This article analyzes the topographic characterization of the surface and wear processes in injection molds cavities. Two materials have been used to produce(More)
