Energy management control strategies for energy storage systems of hybrid electric vehicle: A review
Get PDFContinuous efforts to preserve the environment and to reduce gaseous emissions due to the massive growth of urban economic development and heightened concerns over crude oil depletion have accelerated researchers to find long-term solutions, particularly in the transportation sector with the focus on powertrain electrification. This article delivers a comprehensive overview of electric vehicle architectures, energy storage systems, and motor traction power. Subsequently, it emphasizes different charge equalization methodologies of the energy storage system. This work's contribution can be identified in two points: first, providing an overview of different energy management methods to researchers and scholars. Second, to highlight the state-of-the-art leanings in major components and to highlight promising approaches to hybrid electric vehicle future development
Experimental evaluation of the use of cruciform specimens for biaxial stability analysis
Get PDFNovel research is proposed about the suitability of cruciform specimens for estimating the stress-strain response and buckling modes of flat laminates under equibiaxial compression. The experimental challenge lies in determining whether the specimen design and test procedure can be adequate to observe geometric instability at the coupon scale with small dimensions of the tested region
Responsible consumers are made, not born: a clothing secondhand market experience in two Spanish high schools
Get PDFThis article presents the assessment of two educational secondhand clothing markets developed at two high schools in Albacete. One of them involved money and the other was based on barter, and both included an awareness raising phase to promote responsible consumption. Although all students were involved, only those who organized the experience were surveyed (N = 40, 21 females). Data were gathered after the experience, in students regular classrooms. A qualitative methodology was used, combining focus groups and an open ended questionnaire. Findings were similar in both groups: the experience was positively perceived, although there was an initial stigmatized preconception surrounding secondhand clothing; it also helped students learn and become aware of the environmental impact of clothing, making them reflect on their consumption habits and change them. Students also perceived some barriers to reducing their consumption. Thus, secondhand markets can be powerful educational tools to raise awareness and change behaviors toward more prosustainable choices
Estudio de caso en una familia con un niño con síndrome de PACS1 mediante la escala PICCOLO
Get PDFLos Modelos Centrados en la Familia del ámbito de la Atención Temprana dan como resultado el empoderamiento familiar junto a una mayor competencia de los menores en las rutinas. El presente estudio de intervención de caso único se ha realizado bajo este modelo. Durante un año, se ha acompañado a la familia de un niño con síndrome de PACS1, un trastorno del neurodesarrollo de origen genético y muy baja prevalencia. Mediante la Escala PICCOLO de observación de las interacciones parentales con los/las niños/as, se analizaron grabaciones mensuales del padre jugando con su hijo. Tras establecer tres meses de evaluación de línea base, se realizaron devoluciones bimensuales por videoconferencia a la familia, basadas en sus preocupaciones y en aspectos concretos de cada uno de los 4 dominios de la escala, con el fin de facilitar su comprensión del desarrollo e interacciones con el menor. El padre se encontraba en la media poblacional de puntuaciones en estos cuatro dominios, y evolucionó positivamente y de forma constante en uno de los objetivos de intervención planteados (ítem 3 de la escala de enseñanza: “Repite o expande las palabras o los sonidos del niño”). Al finalizar, se valoró con la familia este modo de intervención destacando la utilidad del visionado de las grabaciones a posteriori y su sensación de competencia
Estudio de prevalencia de amiloidosis cardíaca en pacientes con estenosis del canal lumbar e hipertrofia del ligamento amarillo
Get PDFLa estenosis de canal lumbar (ECL) es una condición frecuente entre los pacientes con amiloidosis cardiaca (AC). Sin embargo, se desconoce la prevalencia de AC entre los pacientes con AC. El objetivo de la presente investigación fue evaluar la prevalencia de AC entre los pacientes con ECL. También se exploró el papel de la hipertrofia del ligamento amarillo (HLA) para establecer la sospecha de AC.
Métodos: Se realizó un estudio transversal en que se incluyeron pacientes consecutivos con ECL e HLA. En todos los casos se llevó a cabo una evaluación que incluía una valoración clínica, un electrocardiograma, un ecocardiograma y una analítica. Se definieron como casos de sospecha de AC aquellos que presentaban alguna red flag de la enfermedad y presentaban hipertrofia ventricular. En éstos se completó el estudio con una valoración específica con resonancia cardiaca y gammagrafía con 99mTc-DPD para determinar la presencia de amiloide. Se empleó como grupo control una cohorte histórica de pacientes con AC confirmada y ECL para determinar las características clínicas asociadas a la AC.
Resultados: Ciento cinco pacientes (75,0 ± 6,6 años; 45,7% varones) con ECL e HLA [ 5,5 (5-7) mm] fueron evaluados. La presencia de red flags de AC fue muy frecuente y 58 pacientes (55,2%) cumplieron la definición de sospecha de AC. Tras la valoración específica, 1 paciente (0,95%) fue diagnosticado de AC.
Los pacientes con AC confirmada presentaron un fenotipo muy expresivo de la enfermedad, a diferencia de la cohorte de screening.
Los pacientes con sospecha de AC, así como los pacientes con AC confirmada presentaron un mayor grado de HLA que aquellos sin sospecha de AC [ (6,3 ± 1,3 vs. 5,0 ± 0,8 mm; p <0,001) y (6,7 ± 1,8 vs. 5,0 ± 0,8 mm; p=0,018), respectivamente ]. El grosor del ligamento amarillo se correlacionó con el número de red flags de AC en los pacientes con sospecha (r: 0,33; p <0,001).
Conclusiones: A pesar de que las red flags de AC son frecuentes en pacientes con ECL e HLA, la prevalencia de AC resultó baja en nuestra muestra. La valoración del grado de HLA podría tener un papel en la identificación de casos con sospecha de AC
Effect of the Organizational Model of the Subject of Activities in the Natural Environment on Students’ Satisfaction and Learning
Get PDFThe aim of this study was to identify the most suitable organizational model for teaching the university subject of Outdoor Activities in relation to learning acquisition and satisfaction. For this purpose, four models were designed, some of which were dominated by traditional education and others by innovative education. The data collection instruments were the Spanish version of the Physical Education of the Sport Satisfaction Instrument, adapted to the university context, and the questionnaire on the contents of the subject designed ad hoc. Data collection was carried out before and after the intervention with a total of 125 students. For data analysis, an ANCOVA was performed. The results showed that there were significant differences in satisfaction between groups (p = 0.029), but not in the boredom scale (p = 0.109). With regard to acquisition of learning between groups, there were significant differences (p = 0.005) in the overall grade of the subject. There were also significant differences in the scores for content taught differently depending on the group (p = 0.003), with a higher score in the most innovative group, the intensive-continuous group, compared to the fractioned (p = 0.005) and classic groups (p = 0.015). It is concluded that there is a positive effect between direct and continuous contact with nature, both in the acquisition of learning and in student satisfaction, with the most innovative model obtaining the best results of the stud
All-Small-Molecule Ternary Organic Solar Cell with 16.35% Efficiency Enabled by Chlorinated Terminal Units
Get PDFIn the last few years, there have been notable developments in organic solar cells using both small molecule donor and acceptor. It has been noted that adding halogens to the end groups of small molecules could enhance the film structure and, consequently, the performance of the devices. In this study, three novel small molecule donors are created. The molecules include a vinyl-CPDT oligomer with three units, with end-caps made up of indanedione groups and containing four H, four Cl, and four F substituents. The purpose of the study is to investigate how the halogen substituent affects the photovoltaic characteristics of binary devices made with the non-fullerene acceptor (NFA) TOCR2 as the acceptor. Having the halogen in the device enhances its effectiveness, and FG5, which has 4-Cl substituents in the end groups, shows the highest efficiency among all devices with a PCE of 14.39%. Incredibly, the ternary device that is created in normal atmospheric conditions with chloro-substituted FG5 as the donor, TOCR2 as the acceptor, and the wide band gap NFA DICTF as the third element shows significantly improved efficiency, achieving PCE values of up to 16.35%

II Estadísticas de las TAE y precios medios aplicados a los micropréstamos (2024)
Get PDFLa doctrina en materia de usura sentada por el Tribunal Supremo, desde la sentencia de 25.11.2015 (RJ 2015\5001) prevé recurrir a las estadísticas del Banco de España para determinar cuál es el interés normal del dinero (a efectos del art. 1 de la Ley de Usura). Además, a partir de la STS 4.3.2020 (RJ 2020\407), el Alto Tribunal viene insistiendo en que el tipo medio de interés que ha de tomarse de las estadísticas que se usen como referencia, tiene que ser el del mercado específico del producto controvertido . Sin embargo, en materia de préstamos no hipotecarios extrabancarios, no existen estadísticas públicas ya que los prestamistas no entidades de crédito no son entidades declarantes según la Circular 1/2010, ni están sujetos a registro previo. En consecuencia, nos propo nemos reflejar los tipos y precios medios aplicados a los micropréstamos, con datos actualizados para todo el ejercicio 2023, así como demostrar que la TAE no es un indicador que permita representar la onerosidad de un micropréstamo, por el efecto exponencial que provoca la frecuencia de pagos que incorpora su fórmul
