Análisis y priorización de las soluciones técnico-económicas para paliar la pobreza energética en la ciudad de Valencia
[ES] El objetivo del TFG es ayudar a solucionar un problema que sufren en torno a 30.000 familias en el municipio de Valencia. La pobreza energética se debe a tres causas principales: i) los costes altos de la energía en relación a sus ingresos bajos, ii) la mala calidad energética de las viviendas y iii) los malos hábitos de consumo de energía. El problema de la pobreza energética lleva a que las familias tengan mayores índices de enfermedad física y psicológica, a prácticas arriesgadas para no pagar la energía, y a exclusión social.
En el TFG se parametriza en términos cuantitativos la pobreza energética y se buscan soluciones. Estas soluciones, alrededor de 15 diferentes, se clasificarán en "Económicas", de "Rehabilitación energética de viviendas", de "Eficiencia energética de equipos de viviendas", de "Nuevos sistemas energéticos para viviendas" y de "Cultura energética". Son soluciones como rehabilitar energéticamente las viviendas, rediseñar el sistema de suministro de energía, auditorías energéticas, etc. que requieren de una formación en ingeniería para poder entender cómo y cuánto pueden contibuir á plaiar la pobreza energética. A continuación se caracteriza cada solución desde la ingeniería energética, y se evalúan en base a diversos criterios técnicos, ambientales, económicos y sociales. Tanto cuantitativos como cualitativos.
Para identificar estos criterios se realiza una revisión bibliográfica, se hacen entrevistas con expertos, y pequeños proyectos tipo de actuación, según cada solución. Los criterios que se manejan son 13 e incluyen citerios económicos como: coste de la intervención, coste de explotación, periodo de retorno, etc. criterios técnicos como energía ahorrada, viabilidad técnica, plazo de la intervención, etc. Criterios ambientales como gases de efecto invernadero ahorrados, y sociales como sinergias con la economía local, creación de dependencia en las familias, viabilidad lega actual, etc.
Los resultados del TFG permiten priorizar las soluciones técnicas a la pobreza energética en función de la situación de cada familia, y de los recursos técnicos y económicos de la administración pública municipal. Este TFG está previsto que contribuya a la programación de las actuaciones contra la pobreza energética de los técnicos del servicio de Energías Renovables y Cambio Climático del ayuntamiento de Valencia.[EN] The goal of the TFG is to help to solve a problem suffered by around 30,000 families in the municipality of Valencia. Fuel poverty is due to three main causes: i) high energy costs in relation to low income, ii) poor energy quality of homes and iii) poor energy consumption habits. The problem of energy poverty leads families to have higher rates of physical and psychological illness, risky practices to avoid paying for energy, and social exclusion.
In the TFG, energy poverty is parameterized in quantitative terms and solutions are sought. These solutions, around 15 different, will be classified as "Economic", "Energy rehabilitation of homes", "Energy efficiency of residential equipment", "New energy systems for homes" and "Energy culture". These are solutions such as energy subsidies, energy rehabilitation of homes, redesigning the energy supply system, energy audits, etc. They require engineering training to understand how and how much they can contribute to plaiar energy poverty. Each solution is then characterized based on energy engineering, i.e. they are evaluated based on various technical, environmental, economic and social criteria. both quantitative and qualitative.
In order to identify these criteria, a bibliographic review is carried out, interviews are conducted with experts, and small projects of action, according to each solution. The criteria that are handled are 13 and include economic criteria such as: cost of intervention, cost of exploitation, payback period, etc. technical criteria such as energy saved, technical feasibility, durtion of intervention, etc. Environmental criteria such as greenhouse gases saved, and social criteria like synergies with the local economy, creation of dependence on families, current legal viability, etc.
The results of the TFG allow prioritizing technical solutions to energy poverty depending on the situation of each family, and the technical and economic resources of the municipal public administration. This TFG is expected to contribute to the programming of the actions against the fuel poverty of the technicians of the Renewable Energy and Climate Change service of the city of Valencia.Valls Carbonell, J.

Anatomía sensitiva de la rodilla. Anatomía e implicaciones clínicas
El dolor de rodilla es una condición extremadamente frecuente en personas de avanzada edad. Su tratamiento en ocasiones presenta severos condicionantes. La sustitución de la articulación de la rodilla por una prótesis es la mejor opción de tratamiento de diversas patologías sin embargo en determinadas ocasiones persiste el dolor tras la cirugía. Descripciones previas han considerado a los nervios geniculares como los responsables de vehiculizar ese dolor.
La inervación es compleja y sujeta a importante variabilidad entre individuos siendo necesaria una precisa descripción del recorrido de los nervios con el fin de mejorar los resultados.
El objetivo de este estudio es aumentar el conocimiento acerca de estas ramas sensitivas y proveer de patrones ecográficos para su localización
Improving accuracy of the intermediate splint in substantial intermaxillary sagittal discrepancies using an extra anterior anchorage point:technical note
To describe a technical feature that increases the stability of the intermediate splint in patients where bimaxillary surgery with great maxillary/mandibular advancements are planned. Prospective evaluation of the intermediate splint dental vertical penetration in patients undergoing bimaxillary surgery where great sagittal discrepancy occur in the anterior sector between the upper and lower jaws when the intermediate splint is placed by adding an extra intermaxillary fixation (IMF) screw (2x9 mm) placed between the central incisors of the maxilla and fixed to the most anterior aspect of the intermediate splint following the direction of the sagittal maxillo-mandibular discrepancy from January to September 2018. The postoperative evaluation comparing the accuracy of conventional fixation versus fixation with an extra anterior anchorage point through photographic assessment and intraoral digital scanner demonstrated better dental penetration, and therefore improved intermediate splint precision with the latter in all cases Our results suggest that this is a simple and safe technique that can be easily reproduced and optimizes the outcomes by increasing the accuracy of translation of the planned surgical movements to the operating room
Integration of Data Distribution Service and distributed partitioned systems
[EN] Avionics systems are complex and time-critical systems that are progressively adopting more flexible (though equally robust) architectural designs. Although a number of current avionics systems follow federated architectures, the Integrated Modular Avionics (IMA) paradign is becoming the dominant style in the more modern developments. The reason is that the IMA concept promotes modular designs where applications with different levels of criticality can execute in an isolated manner in the same hardware. This approach complies with the requirements of cost, safety, and weight of the avionics systems. FACE standard (Future Airborne Capability Environment) defines the architectural baseline for easing integration in avionics systems, including the communication functions across distributed components. As specified in FACE, middleware will be integrated into avionics systems to ease development of portable components that can interoperate effectively. This paper describes the usage of publish-subscribe middleware (precisely, DDS - Data Distribution Service for real-time systems) into a fully distributed partitioned system. We describe, from a practical point of view, the integration of the middleware communication overhead into the hierarchical scheduling (as compliant with ARINC 653) to allow the usage of middleware in the partitions. We explain the design of a realiable communication setting, exemplified on a distributed monitoring application in a partitioned environment. The obtained implementation results show that, given the stable communication overhead of the middleware, it can be integrated in the time windows of partitions.This work has been partly supported by the Spanish Ministry of Economy and Competitiveness through projects REM4VSS (TIN 2011-28339) and M2C2 (TIN2014-56158-C4-3-P).Garcia-Valls, M.; Domínguez-Poblete, J.; Eddine Touahria, I.; Lu, C.

To achieve an earlier IFN-¿ response is not sufficient to control mycobacterium tuberculosis infection in mice
The temporo-spatial relationship between the three organs (lung, spleen and lymph node) involved during the initial stages
of Mycobacterium tuberculosis infection has been poorly studied. As such, we performed an experimental study to evaluate
the bacillary load in each organ after aerosol or intravenous infection and developed a mathematical approach using the
data obtained in order to extract conclusions. The results showed that higher bacillary doses result in an earlier IFN-c
response, that a certain bacillary load (BL) needs to be reached to trigger the IFN-c response, and that control of the BL is
not immediate after onset of the IFN-c response, which might be a consequence of the spatial dimension. This study may
have an important impact when it comes to designing new vaccine candidates as it suggests that triggering an earlier IFN-c
response might not guarantee good infection control, and therefore that additional properties should be considered for
these candidates.Peer ReviewedPostprint (published version
Improving the ability of image sensors to detect faint stars and moving objects using image deconvolution techniques
In this paper we show how the techniques of image deconvolution can increase
the ability of image sensors as, for example, CCD imagers, to detect faint stars or faint
orbital objects (small satellites and space debris). In the case of faint stars, we show that this
benefit is equivalent to double the quantum efficiency of the used image sensor or to
increase the effective telescope aperture by more than 30% without decreasing the
astrometric precision or introducing artificial bias. In the case of orbital objects, the
deconvolution technique can double the signal-to-noise ratio of the image, which helps to
discover and control dangerous objects as space debris or lost satellites. The benefits
obtained using CCD detectors can be extrapolated to any kind of image sensorsPeer ReviewedPostprint (published version
Circulating inflammatory biomarkers and academic performance in adolescents: DADOS study
Objective
The present study aimed (1) to examine the association between circulating inflammatory
biomarkers and academic performance in adolescents, and (2) to identify the ability of circulating inflammatory biomarkers to predict low academic performance.
Methods
A total of 244 adolescents (13.9±0.3 years, 112 girls) from the DADOS study were included
in the analysis. Four inflammatory biomarkers were quantified: white blood cell (WBC)
count, interleukin-6, tumor necrosis factor-α (TNF-α), and C-reactive protein (CRP). Academic performance was assessed through academic grades and the Spanish version of the
Science Research Associates Test of Educational Abilities.
Results
TNF-α was inversely associated with math, Spanish and grade point average (β ranging
from -0.166 to -0.124; all p<0.05), while CRP was inversely associated with verbal ability (β
= -0.128; p<0.05). Overall, receiver operating characteristic (ROC) curves analyses showed
discriminatory ability of WBC and TNF-α in identifying low academic performance (all
p<0.05). Moreover, logistic regression analyses indicated that students with levels of WBC
and TNF-α above the ROC cut-offs values showed between 78% to 87% increased likelihood of lower academic performance (p<0.05).
Conclusions
Our findings suggested that some circulating inflammatory biomarkers were associated with
academic performance in adolescents. Further larger longitudinal and interventional studies
are needed to clarify the short-term and long-term relationship between inflammation and
academic performance in youths
Longitudinal Associations of Healthy Behaviors on Fitness in Adolescents: DADOS Study
Introduction:
This study aims to investigate the individual and combined associations of physical activity, sedentary time, diet, and sleep at baseline on cardiorespiratory fitness at 24-month follow-up in adolescents.
Methods:
The DADOS (Deporte, ADOlescencia y Salud) prospective cohort study was performed between 2015 and 2017. Analyses were conducted in 2020 and included 189 adolescents aged 13.9 (SD=0.3) years at baseline. Vigorous physical activity, total sedentary time, and sleep duration were evaluated by GENEActiv accelerometer. Sleep quality and adherence to a Mediterranean diet were evaluated by questionnaires. Cardiorespiratory fitness was assessed by the 20-meter shuttle run test. A healthy lifestyle index was created by including positive scores for each individual behavior, and 3 categories of achievement (≤1, 2, ≥3) were established.
Results:
Performing high vigorous physical activity and low screen time at baseline were individually associated with the likelihood of achieving high cardiorespiratory fitness at follow-up (OR=3.33 and 3.09, respectively). ANCOVA indicated that adolescents with a healthy lifestyle index ≥3 at baseline showed higher cardiorespiratory fitness at follow-up than those with a healthy lifestyle index of 2 and ≤1 (74.4 [SE=1.5] vs 68.9 [SE=1.4] and 67.8 [SE=1.5] laps, respectively; p<0.01). Adolescents with a healthy lifestyle index ≥3 at baseline were more likely to have high cardiorespiratory fitness at follow-up (OR=3.10) than their peers with ≤1.
Conclusions:
The results showed a cumulative impact of baseline health-related behaviors on cardiorespiratory fitness at 24-month follow-up in adolescents. These findings underline the key role of promoting a healthy lifestyle to improve adolescents’ health.Funding for open access charge: CRUE-Universitat Jaume IThe DADOS study is funded by the Spanish Ministry of Economy and Competitiveness (DEP2013–45515-R) and by the University Jaume I of Castellón (P1•1A2015-05 and UJI-A2019-12).
