Evaluación del potencial fotovoltaico del Campus Sur de la Universidad Politécnica de Madrid
El presente proyecto engloba el estudio del potencial fotovoltaico del Campus Sur de la Universidad
Politécnica de Madrid.
Este estudio se divide en tres partes. En primer lugar, se calcula la productividad del campus. En segundo lugar, se diseña la disposición de los generadores fotovoltaicos en los terrenos disponibles.
Como paso final, se realiza un estudio económico de distintos supuestos.
Para realizar los cálculos de productividad, se utiliza IESPRO, un programa desarrollado en Matlab©, junto con una aplicación complementaria desarrollada en el mismo lenguaje. Gracias a estos dos software es posible obtener una estimación muy realista de la energía anual generada.
El aprovechamiento del terreno se estudia con la ayuda del software libre Sketchup©. Gracias a esta aplicación, es posible la reconstrucción del Campus Sur en 3D. Dicha reconstrucción incluye edificaciones y vegetación, facilitando la distribución de los generadores fotovoltaicos en todas las zonas, pudiendo evitar zonas con sombreado o no aptas para la instalación, y maximizando la utilización del terreno.
El conjunto de los análisis anteriores permiten determinar el rendimiento energético del Campus Sur en sus distintas configuraciones, es decir, únicamente instalando generadores fotovoltaicos en las azoteas de los edificios, o la instalación en todo el terreno disponible, el cual incluye las azoteas y los descampados.
Este rendimiento energético, comparado con el consumo anual de todo el campus, permite estimar el coste financiero de llevar a cabo la instalación y su rentabilidad, todo ello detallado en el estudio económico.
El estudio económico se basa en dos supuestos, el primero de ellos, únicamente tiene en cuenta la instalación en las azoteas de los edificios. El segundo estudio, incluye los descampados y las azoteas.
Con estos dos estudios se puede verificar la viabilidad del proyecto, facilitando datos concretos sobre las ventajas de cada uno de ellos.
ABSTRACT.
The aim of this work is to study the photovoltaic potential in the South Campus of the Polytechnic University of Madrid.
The work has been divided into three parts. The first one is focused on the calculus of the solar harvesting productivity of the South Campus. The second part is centered in the development of the complete photovoltaic system layout design, taking into account the available placement. In the third part, an economic study considering several different scenarios is carried out.
In order to calculate the solar productivity, the MATLAB based software tool IESPRO together with a complementary application developed in MATLAB as well, have been used. These programs allow to obtain an accurate estimation of the generated annual energy.
The land use is studied with the help of free software SketchUp. With this application, it is possible to
rebuild the South Campus in 3D. This reconstruction includes: buildings and vegetation, facilitating
the distribution of photovoltaic generators in all areas, to avoid shaded or unsuitable areas for the installation, and maximizing land use.
All the above analysis allow determining the energy efficiency of the South Campus for two different
configurations, i.e., installing solar photovoltaic arrays only on the roofs of the buildings, or installing
solar photovoltaic arrays throughout the land available, including vacant lots and rooftops.
The facilities final cost and the cost effectiveness are estimated by comparing the energy efficiency with the South Campus total consumption. This study is based on two different scenarios: the first one considers the solar arrays installation in the buildings roofs, and the second one includes in the layout the vacant lots and rooftops. These studies allow verifying the feasibility of the project, and provide specific information related to the advantages and drawbacks of each scenario
Practical issues for testing thin film PV modules at standard test conditions.
Thin film photovoltaic (TF) modules have gained importance in the photovoltaic (PV) market. New PV plants increasingly use TF technologies. In order to have a reliable sample of a PV module population, a huge number of modules must be measured. There is a big variety of materials used in TF
technology. Some of these modules are made of amorphous or microcrystalline silicon. Other are made of CIS or CdTe. Not all these materials respond the same under standard test conditions (STC) of power measurement. Power rates of the modules may vary depending on both the extent and the history of sunlight exposure. Thus, it is necessary a testing method adapted to each TF technology. This test must guarantee repeatability of measurements of generated power. This paper shows responses of different commercial
TF PV modules to sunlight exposure. Several test procedures were performed in order to find the best methodology to obtain measurements of TF PV modules at STC in the easiest way. A methodology for indoor measurements adapted to these technologies is described
Water harvesting for young trees using Peltier modules powered by photovoltaic solar energy
Young trees transplanted from nursery into open field require a minimum amount of soil moisture to successfully root in their new location, especially in dry-climate areas. One possibility is to obtain the required water from air moisture. This can be achieved by reducing the temperature of a surface below the air dew point temperature, inducing water vapor condensation on the surface. The temperature of a surface can be reduced by applying the thermoelectric effect, with Peltier modules powered by electricity. Here, we present a system that generates electricity with a solar photovoltaic module, stores it in a battery, and finally, uses the electricity at the moment in which air humidity and temperature are optimal to maximize water condensation while minimizing energy consumption. Also, a method to reduce the evaporation of the condensed water is proposed. The objective of the system is to sustain young plants in drier periods, rather than exclusively irrigating young plants to boost their growth
Influence of a Multidisciplinary Program of Diet, Exercise, and Mindfulness on the Quality of Life of Stage IIA-IIB Breast Cancer Survivors
Background: Integrative oncology has proven to be a useful approach to control cancer symptoms and improve the
quality of life (QoL) and overall health of patients, delivering integrated patient care at both physical and emotional levels.
The objective of this randomized trial was to evaluate the effects of a triple intervention program on the QoL and lifestyle
of women with breast cancer. Methods: Seventy-five survivors of stage IIA-IIB breast cancer were randomized into 2
groups. The intervention group (IG) received a 6-month dietary, exercise, and mindfulness program that was not offered
to the control group (CG). Data were gathered at baseline and at 6 months postintervention on QoL and adherence
to Mediterranean diet using clinical markers and validated questionnaires. Between-group differences at baseline and 3
months postintervention were analyzed using Student’s t test for related samples and the Wilcoxon and Mann-Whitney U
tests. Results: At 6 months postintervention, the IG showed significant improvements versus CG in physical functioning
(p = .027), role functioning (p = .028), and Mediterranean diet adherence (p = .02) and a significant reduction in body
mass index (p = .04) and weight (p = .05), with a mean weight loss of 0.7 kg versus a gain of 0.55 kg by the CG (p = .05).
Dyspnea symptoms were also increased in the CG versus IG (p = .066). Conclusions: These results demonstrate that an
integrative dietary, physical activity, and mindfulness program enhances the QoL and healthy lifestyle of stage IIA-IIB breast
cancer survivors. Cancer symptoms may be better managed by the implementation of multimodal rather than isolated
interventions.Background: Integrative oncology has proven to be a useful approach to control cancer symptoms and improve the

Characterization of Lactobacillus rhamnosus MP01 and Lactobacillus plantarum MP02 and Assessment of Their Potential for the Prevention of Gastrointestinal Infections in an Experimental Canine Model
The aim of the present study was to evaluate the probiotic potential of Lactobacillus rhamnosus MP01 and Lactobacillus plantarum MP02, two strains isolated from canine milk. These two isolates were characterized in vitro for their survival to conditions similar to those found in the canine gastrointestinal tract, production of antimicrobial compounds, adherence to intestinal mucin, degradation of mucin, and antibiotic sensitivity. Globally, both strains exhibited a high in vitro probiotic potential. Finally, their potential for the prevention of gastrointestinal infections was evaluated in an experimental canine model using 1-month-old puppies. A group of 12 German shepherd puppies, 6 males and 6 females, received L. rhamnosus MP01 daily for 2 months and a second group of 12 puppies, 6 males and 6 females, of the same breed received L. plantarum MP02 during the same period of time. The same experimental approach was carried with Yorkshire puppies. Additionally, the trial included 12 dogs of each breed in the placebo groups. The results demonstrated that administration of the strains resulted in a significant preventive effect of gastrointestinal infections in such populations
