Análisis de la evaluación e interrelación de los parámetros de calidad de las masas de agua de una cuenca : zona media de la Cuenca Hidrográfica del Guadiana

El presente trabajo de investigación, pretende realizar un estudio de la evaluación y control de los parámetros de calidad en varias masas de agua de una misma cuenca. En este sentido, se ha concretado el trabajo en las principales masas de agua de la Cuenca Hidrográfica del Guadiana, donde se encuentran, dos de los principales embalses nacionales; el embalse de La Serena, que con sus 3.219 Hm3 de capacidad es el mayor de España y el embalse de Cijara (6º de mayor capacidad del estado con 1.505 Hm3) El resto de embalses sobre los que versa el presente trabajo están, de una manera u otra forma, ligados geográfica e hidrológicamente a los dos mencionados. Se han analizado y estudiado diferentes series de datos de las características físico-químicas, características físicas, características químicas, características químico-biológicas y características bacteriológicas de los embalses de Cijara, Garcia Sola, Orellana, La Serena y Zújar entre los años 2000 y 2012. De éste análisis se desprende que existen relaciones entre líneas de tendencias de diferentes parámetros para los embalses estudiados de la Zona Media de la Cuenca Hidrográfica del Guadiana durante la serie estudiada. En la misma línea, se concluye que, por un lado existen relaciones entre diferentes parámetros de calidad de un mismo embalse, y por otro, que existen relaciones entre varios parámetros de diferentes embalses, con lo que conocido un valor de un parámetro determinado de un embalse se podría estimar (de forma aproximada) otro parámetro determinado de un embalse distinto de la misma cuenca. The present work of investigation tries to conduct a study of the evaluation and control of the quality parameters in several bodies of water in a basin. In this sense, is has completed work in the main bodies of water of the Guadiana hydrographic basin, where they are, two of the main national reservoirs; the reservoir of La Serena, which with its 3.219 Hm3 capacity is the largest in Spain and the embalse de Cíjara (6th largest State with 1.505 Hm3 capacity). The other reservoirs on which deals with this work are, in one way or another way, linked geographical and hydrologic to the two mentioned. They have been analyzed and studied different data series of physicochemical characteristics, physical characteristics, chemical properties, chemical-biological characteristics and features bacteriological of reservoirs of Cíjara, García single, Orellana, La Serena and Zújar between 2000 and 2012. This analysis shows that there are relations between lines of trends of different parameters for the studied reservoirs in the area average of the river Guadiana basin during the series studied. In the same vein, it is concluded that, on the one hand relationships exist between different quality parameters of a reservoir, and on the other, that there are relationships between various parameters of different reservoirs, with known value for a particular parameter of a reservoir could estimate (in approximate form) other specific parameter of a reservoir other than the same basin.

Customer loyalty plan at Residencia Gómez-Pardo, Universidad Politécnica de Madrid

Accommodation is a first need and one of the most important decisions that university students have to decide taking into account their limited budget. The satisfaction grade of these students is the relevant aspect for the administrators and managers of the university residences, because it allows assuring the viability and sustainability of this kind of accommodation. In a situation of decline in rate of retention of students into the residence, coupled with an environment of economic crisis. Hence, of disposable income reduction, it seems essential to get to know what factors affect the motivation to remain into the university residence more than others when it comes to the final choice. The offer?s increase of different kind of accommodation is another variable to be considered when taking the decision related to the management of this kind of accommodation. Thus, there is the need to know which are the key factors and to obtain information about these variables in order to go deep into the relevance grade with the aim to pursue the strategic objectives, that will allow to improve the relationship with the customer and to respond to his accommodation? needs. This article researches the motivation elements that lead the students to remain in a university residence or to abandon it in exchange or a different accommodation, as per example shared flats or individual apartments. This research work intends to be useful for the university residence?s managers in order to increase its incomes, to raise the satisfaction degree among its residents and to obtain better end results in the management of these properties. The fieldwork conducted in the Residencia Universitaria Gómez Pardo (RUGP), Universidad Politécnica de Madrid (UPM), for four semesters, which means students from 27 different grades (undergraduates) and 81 surveys finished, shows the following conclusions. Not only the relation with the residence?s personnel but also the quality and quantity of the feeding and the availability and quality of the internet service, constitute key factors when it comes to make the decision of remaining or of abandoning the residence when the semester comes to its end.

¿Puede ser la estrategia de carrera un factor de Optimización del rendimiento en los 100 metros lisos?

El presente trabajo de fin de grado plantea una hipótesis acerca de la optimización del rendimiento en una carrera de 100 metros lisos mediante la aplicación de una estrategia de carrera adecuada, tras observarse la pérdida de velocidad en la parte final de la carrera. Para ello, se desarrollaron dos objetivos relacionados con el tratamiento y estudio de la cinética de carrera en grupos de distinto nivel atlético con el fin de determinar si su comportamiento en carrera es diferente más allá del propio rendimiento, y tratar de comprobar cuales pueden ser las vías energéticas de optimización de dicho rendimiento en la carrera de 100 metros lisos.

Impact of Impurities on the Mechanical Strength of Multicrystalline Silicon

The usage of more inexpensive silicon feedstock for crystallizing mc-Si blocks promises cost reduction for the photovoltaic market. For example, less expensive substrates of upgraded metallurgical silicon (UMG-Si) are used as a mechanical support for the epitaxial solar cell. This feedstock has higher content of impurities which influences cell performance and mechanical strength of the wafers. Thus, it is of importance to know these effects in order to know which impurities should be preferentially removed or prevented during the crystallization process. Metals like aluminum (Al) can decrease the mechanical strength due to micro-cracking of the silicon matrix and introduction of high values of thermal residual stress. Additionally, silicon oxide (SiOx) lowers the mechanical strength of mc-Si due to thermal residual stresses and stress intensification when an external load is applied in the surrounding of the particle. Silicon carbide (SiC) introduces thermal residual stresses and intensifies slightly the stress in the surrounding of the particle but can have a toughening effect on the silicon matrix. Finally, silicon nitride (Si3N4) does not influence significantly the mechanical strength of mc- Si and can have a toughening effect on the silicon matrix.

Influence of high aluminium content on the mechanical properties of directionally solidified multicrystalline silicon

The purpose of this research is the mechanical characterisation of multicrystalline silicon crystallised from silicon feedstock with a high content of aluminium for photovoltaic applications. The mechanical strength, fracture toughness and elastic modulus were measured at different positions within the multicrystalline silicon block to quantify the impact of the segregation of impurities on these mechanical properties. Aluminium segregated to the top of the block and caused extensive micro-cracking of the silicon matrix due to the thermal mismatch between silicon and the aluminium inclusions. Silicon nitride inclusions reduced the fracture toughness and caused failure by radial cracking in its surroundings due to its thermal mismatch with silicon. However, silicon carbide increased the fracture toughness and elastic modulus of silicon.

Molecular recognition with nanostructures fabricated by photopolymerization within metallic subwavelength apertures

The first demonstration of fabrication of submicron lateral resolution molecularly imprinted polymer (MIP) patterns by photoinduced local polymerization within metal subwavelength apertures is reported. The size of the photopolymerized MIP features is finely tuned by the dose of 532 nm radiation. Rhodamine 123 (R123) has been selected as a fluorescent model template to prove the recognition capability of the MIP nanostructures, which has been evaluated by fluorescence lifetime imaging microscopy (FLIM) with single photon timing measurements. The binding selectivity provided by the imprinting effect has been confirmed in the presence of compounds structurally related to R123. These results pave the way to the development of nanomaterial architectures with biomimetic artificial recognition properties for environmental, clinical and food testing.

Identification of Novel Components of the Unfolded Protein Response in Arabidopsis

Unfavorable environmental and developmental conditions may cause disturbances in protein folding in the endoplasmic reticulum (ER) that are recognized and counteracted by components of the Unfolded Protein Response (UPR) signaling pathways. The early cellular responses include transcriptional changes to increase the folding and processing capacity of the ER. In this study, we systematically screened a collection of inducible transgenic Arabidopsis plants expressing a library of transcription factors for resistance toward UPR-inducing chemicals. We identified 23 candidate genes that may function as novel regulators of the UPR and of which only three genes (bZIP10, TBF1, and NF-YB3) were previously associated with the UPR. The putative role of identified candidate genes in the UPR signaling is supported by favorable expression patterns in both developmental and stress transcriptional analyses. We demonstrated that WRKY75 is a genuine regulator of the ER-stress cellular responses as its expression was found to be directly responding to ER stress-inducing chemicals. In addition, transgenic Arabidopsis plants expressing WRKY75 showed resistance toward salt stress, connecting abiotic and ER-stress responses.
