Item type: Item , DC-DC converter with bipolar output and its use for connection of a distributed generation system to a bipolar dc grid(Centro Científico Tecnológico de Huelva, 2019) Durán Aranda, Eladio; Pérez Litrán, Salvador; Ferrera Prieto, María BellaItem type: Item , Sustainable urban race (sur), a project to educate in scientific and technical vocations of the University of Huelva(Centro Científico Tecnológico de Huelva, 2019)The authors have devised a project that consists of the construction of a solar vehicle with the objective of promoting technical studies among pre-university students, to later carry out a public competition in which to reward the best projects. This paper describes the project carried out at the University of Huelva together with 15 institutes in 2018, as well as some of the results obtained in it.Item type: Item , Theranostic: a new tecnique againts cancer(Centro Científico Tecnológico de Huelva, 2019) Sánchez Segovia, José; Salgado Gracia, C.; Martel Bravo, IsmaelTheranostic, has positioned itself as a promising technique to fight cancer, especially when using radioactive isotopes, where it has demonstrated good efficiency in human cancer treatment and in the animal phase study. The technique basically consists in using a chemical element with several radioactive isotopes. One diagnostic (gamma or β+ emitter) and another isotope of the same therapeutic element (alpha, β+, β- or Auger electrons). These isotopes must be linked to a vector molecule expressed by the tumor cells of the corresponding type of cancer. Radioisotopes can also be encapsulated in nanoparticles.Item type: Item , Electricity microgeneration in pressure hydraulic networks(Centro Científico Tecnológico de Huelva, 2019) Rodríguez Pérez, Ángel Mariano; Pérez Calañas, Cinta; Pulido Calvo, InmaculadaThe aim of this study is to analyze and evaluate the installation of microturbines placed at selected points of water distribution systems to generating electricity from excess and unused hydraulic energy. In order to achieve this objective, we have considered some alternatives to installation in hydraulic pressurized networks of two municipalities in the province of Huelva: Cañaveral de León and Aracena. These water distribution systems are managed by the public company Giahsa. An economic feasibility analysis of the proposed installation alternatives as well as a proposal for amortization of the investment were shown in this work.Item type: Item , New single-input, multiple-output converter topologies: combining singleswitch non-isolated dc-dc converters for single-input multiple-output applications(Centro Científico Tecnológico de Huelva, 2019) Ferrera Prieto, María Bella; Pérez Litrán, Salvador; Durán Aranda, EladioThis paper presents a methodology that allows the development of new converter topologies for single-input, multiple-output (SIMO) from different basic configurations of singleinput, single-output dc–dc converters. These typologies have in common the use of only one powerswitching device and they are all non-isolated converters. Sixteen different topologies are highlighted, and their main features are explained. The 16 typologies include nine two-output-type, five threeoutput- type, one four-output-type, and one sixoutput- type dc–dc converter configurations. In addition, an experimental prototype of a three-outputtype configuration with six different output voltages based on a single-ended primary inductance (SEPIC)- Cuk-boost combination converter was developed, and the proposed design methodology for a basic converter combination was experimentally verified.Item type: Item , An open hardware electronic controller for motorized rotary injection valves used in flow injection analysis(Centro Científico Tecnológico de Huelva, 2019) Mozo Llamazares, Juan Daniel; Otero, J. I.; Durán Aranda, Eladio; Semião, JorgeThis work presents the design, development and the implementation of a motorized injection valve used in Flow Injection Analysis systems. The built prototype has been developed based on the open hardware, software and firmware, emergent philosophy thus helping the development of a free and independent science. This policy creates a platform of open projects that feed each other, contributing to scientific and technological development while sharing knowledge. The proposed design project can be modified to implant it in other devices or projects according to the needs of each one. Also, the open project can be a great help as teaching material in Universities, since open hardware projects are fully described and documented.Item type: Item , The UHU Open Source Hardware Group(Centro Científico Tecnológico de Huelva, 2019) Mozo Llamazares, Juan Daniel; Durán Aranda, EladioItem type: Item , The ICH15 project: design study of a proton accelerator sistem for production of radioactive isotopes and treatment of uveal melanoma by using IH/CH rRF-cavities(Centro Científico Tecnológico de Huelva, 2019) Sánchez Segovia, José; Martel Bravo, Ismael
