Los productos biocidas presentan una serie de limitaciones para su uso como son: -Perfil toxicológico que limita su utilización en todos lo ámbitos. -Solubilidad que imposibilita o dificulta la utilización del agua como vehículo de elección. -Estado físico que en algunos casos complica la manipulación del biocida por el operador. -Condiciones de almacenamiento que precisan protección frente a la luz y a la temperatura. En esta memoria se plantea como solución a esta problemática, la formación de microencapsulados (complejos de inclusión) de biocidas de tres familias diferentes (nicotinoides, piretroides y carbamatos) y del sinergista butóxido de piperonilo, con ciclodextrinas (oligosacáridos cíclicos). El objetivo de esta investigación es desarrollar las herramientas adecuadas que permitan obtener un producto medioambientalmente compatible, que sirva de base para la obtención de formulaciones eficaces aplicables al control de plagas de insectos voladores, concretamente enfocado a la mosca doméstica (Musca doméstica), tanto en el interior como en el exterior de entornos urbanos y ganaderos. Una vez obtenido el microencapsulado se lleva a cabo su caracterización mediante diversas técnicas analíticas instrumentales: -Electroforesis capilar de zona (ECZ). -Estudios de solubilidad de fase mediante espectroscopía uv-vis. -Estudios calorimétricos (DSC, TG y DTA). -Resonancia Magnética Nuclear (RMN-H1 y RMN-C13). -Análisis Elemental (AE). -Microscopía Electrónica de Barrido (SEM). -Espectroscopía Infrarroja con Transformada de Fourier (FT-IR).

Cardiovascular diseases are nowadays the first cause of mortality worldwide, causing around the 30% of global deaths each year. The risk of suffering from cardiovascular illnesses is strongly related to some factors such as hypertension, high cholesterol levels, diabetes, obesity The combination of these different risk factors is known as metabolic syndrome and it is considered a pandemic due to the high prevalence worldwide. The pathology of the disorders implies a combined cardiovascular therapy with drugs which have different targets and mechanisms of action, to regulate each factor separately. The simultaneous analysis of these drugs turns interesting but it is a complex task since the determination of multiple substances with different physicochemical properties and physiological behavior is always a challenge for the analytical chemist. The complexity of the biological matrices and the difference in the expected concentrations of some analytes require the development of extremely sensitive and selective determination methods. The aim of this work is to fill the gap existing in this field of the drug analysis, developing analytical methods capable of quantifying the different drugs prescribed in combined cardiovascular therapy simultaneously. Liquid chromatography andem mass spectrometry (LCMS/MS) has been the technique of choice throughout the main part of this work, due to the high sensitivity and selectivity requirements.

Tracking the evolution of research in waste recycling science (WRS) can be valuable for environmental agencies, as well as for recycling businesses. Maps of science are visual, easily readable representations of the cognitive structure of a branch of science, a particular area of research or the global spectrum of scientific production. They are generally built upon evidence collected from reliable sources of information, such as patent and scientific publication databases. This study uses the methodology developed by Rafols et al. (2010) to make a “double overlay map” of WRS upon a basemap reflecting the cognitive structure of all journal-published science, for the years 2005 and 2010. The analysis has taken into account the cognitive areas where WRS articles are published and the areas from where it takes its intellectual nourishing, paying special attention to the growing trends of the key areas. Interpretation of results lead to the conclusion that extraction of energy from waste will probably be an important research topic in the future, along with developments in general chemistry and chemical engineering oriented to the recovery of valuable materials from waste. Agricultural and material sciences, together with the combined economics, politics and geography field, are areas with which WRS shows a relevant and ever increasing cognitive relationship.

A partir del análisis del perfil del ingeniero en la sociedad europea, se ha elaborado una encuesta amplia mediante la que se solicitó a las empresas del entorno las competencias y materias que consideraban más importantes en la formación de los ingenieros de las titulaciones ofertadas en la Escuela. A partir de los resultados de dichas encuestas, se establece un perfil requerido a los titulados.

Background: Cognitive impairments are seen in first psychotic episode (FEP) patients. The neurobiological underpinnings that might underlie these changes remain unknown. The aim of this study is to investigate whether Brain Derived Neurotrophic Factor (BDNF) levels are associated with cognitive impairment in FEP patients compared with healthy controls. Methods: 45 FEP patients and 45 healthy controls matched by age, gender and educational level were selected from the Basque Country area of Spain. Plasma BDNF levels were assessed in healthy controls and in patients. A battery of cognitive tests was applied to both groups, with the patients being assessed at 6 months after the acute episode and only in those with a clinical response to treatment. Results: Plasma BDNF levels were altered in patients compared with the control group. In FEP patients, we observed a positive association between BDNF levels at six months and five cognitive domains (learning ability,immediate and delayed memory, abstract thinking and processing speed) which persisted after controlling for medications prescribed, drug use, intelligence quotient (IQ) and negative symptoms. In the healthy control group, BDNF levels were not associated with cognitive test scores. Conclusion: Our results suggest that BDNF is associated with the cognitive impairment seen after a FEP. Further investigations of the role of this neurotrophin in the symptoms associated with psychosis onset are warranted.

Partiendo de un enfoque de orientación al mercado, el presente trabajo analiza la influencia que ejercen diversos factores sobre la efectividad de las promociones basadas en precios. Dichos factores están relacionados tanto con el comportamiento de compra (importancia del precio dentro del proceso de decisión y nivel de conocimiento de los precios que poseen los compradores) como con las características socioculturales y demográficas de los consumidores (sexo, nivel de formación y nivel de ingresos). El trabajo empírico desarrollado, basado en una muestra de 600 consumidores, ha permitido trazar un perfil que define a los consumidores más proclives a sentirse atraídos por los precios promocionales
