The Flipper classroom as an alternative methodology for mathematics education in university teaching
Este trabajo de investigación se ha realizado con los objetivos de conocer los resultados obtenidos
tras haber implementado propuestas didácticas basadas en la metodología de Clase Invertida (Flipped
Classroom) en distintas asignaturas de matemáticas en diferentes cursos y titulaciones de la Universidad
de Málaga; analizar la viabilidad didáctica de esta innovación; y su continuidad. Todo ello orientado
a buscar nuevos modelos educativos que fomenten el trabajo colaborativo, la adaptación a
distintos ritmos de aprendizaje, clases más prácticas y experimentales, que impulse el trabajo autónomo,
y la autorregulación en el aprendizaje.
Los resultados obtenidos, una vez realizado el estudio del grado de satisfacción del alumnado universitario
con la metodología flipped classroom, concluyen que existe una amplia satisfacción con la introducción
de una metodología que le proporciona mayor participación en el aula, que le facilita el
acceso a contenidos didácticos en un formato más cercano (que puede consultar cuándo y cómo
quiera), y que se adapta a sus necesidades y ritmos de aprendizaje. Consideran que el tiempo en el
aula es más eficaz, estiman que realizan un mejor aprovechamiento del tiempo y que además mejora
su aprendizaje y la comprensión de contenidos. Estas conclusiones se han podido contrastar en los
distintos grupos y en diferentes etapas en las que se ha llevado a cabo la experiencia.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
Highly Conductive Zinc Oxide Based Transparent Conductive Oxide Films Prepared using RF Plasma Sputtering Under Reducing Atmosphere
The spectral properties and colour functions of a radio frequency (RF)-based sputtering plasma source was monitored during consecutive sputter deposition of zinc doped indium oxide (IZO) thin films under argon and argon/hydrogen mix. The effect of target exposure to the hydrogen gas on charge density/mobility and spectral transmittance of the deposited films was investigated. We demonstrate that consecutive exposure to the hydrogen gas during the deposition process progressively affects the properties of thin films with a certain degree of continuous improvement in electrical conductivity while demonstrating that reverting to only argon from argon/ hydrogen mix follows a complex pathway, which has not been reported previously in such detail to our knowledge. We then demonstrate that this effect can be used to prepare highly conductive zinc oxide thin films without indium presence and as such eliminating the need for the expensive indium addition. We shall demonstrate that complexity observed in emission spectra can be simply identified by monitoring the colour of the plasma through its colour functions, making this technique a simple real-time monitoring method for the deposition process
Evaluación de la conservación vial del pavimento de la av. Grau entre av. Chulucanas y av. Bellavista, Piura, utilizando el método PCI
El presente trabajo de investigación tuvo como objetivo determinar el estado de
conservación del pavimento flexive de la Av. Grau entre la Av. Chulucanas y la Av.
Bellavista de la ciudad de Piura. Para ello se calculó el Índice de Condición del Pavimento
(PCI), cuyo procedimiento se encuentra descrito en el estándar ASTM D6433 – 18. Dicha
metodología tiene una escala de calificación entre 0 y 100, donde el mínimo valor
representa un pavimento fallado y el máximo un pavimento en buen estado.
La inspección visual sobre el pavimento de la Av. Grau se realizó teniendo como base los
20 daños considerados por el método en su versión 2018, además del nivel de severidad
y la proporción en la que se encuentra cada uno de ellos con respecto al área de su unidad.
Con esta información y las curvas de valores deducibles que proporciona el estándar, se
pudo determinar que el índice Condición del Pavimento en el tramo 01 es de 82 y para el
tramo 02 fue de 72. En promedio se obtuvo un valor PCI de 77, que es indicativo de un
pavimento en estado satisfactorio.
Finalmente, con la ayuda de la información recogida en campo, se proponen algunas
medidas correctivas para evitar que los deteriores sigan aumentando en su severidad y
terminen afectando gravemente la condición del pavimento. Estas medidas van desde un
sellado de grietas y cambio de parches, hasta realizar sobrecarpetas y reconstrucciones.
Las opciones de reparación se basaron en las sugerencias que ofrece el manual del Ing.
Luis Ricardo Vásquez Varela y teniendo en cuenta que resulte económicamente posible su
ejecución.The purpose of this research work was to determine the state of preservation of the
flexural pavement of Grau Avenue between Chulucanas Avenue and Bellavista
Avenue in the city of Piura. For this purpose, the Pavement Condition Index (PCI)
was calculated, whose procedure is described in the ASTM D6433 - 18 standard.
This methodology has a rating scale between 0 and 100, where the minimum value
represents a failed pavement and the maximum value represents a pavement in
good condition.
The visual inspection on the pavement of Grau Avenue was performed based on
the 20 damages considered by the method in its 2018 version, in addition to the
severity level and the proportion in which each of them is found with respect to the
area of its unit. With this information and the deductible value curves provided by
the standard, it was possible to determine that the Pavement Condition Index in
section 01 is 82 and for section 02 it was 72. On average, a PCI value of 77 was
obtained, which is indicative of a pavement in satisfactory condition.
Finally, with the help of the information collected in the field, some corrective
measures are proposed to prevent the deterioration from continuing to increase in
severity and end up seriously affecting the condition of the pavement. These
measures range from crack sealing and patch replacement to overlaying and
reconstruction. The repair options were based on the suggestions offered in Luis
Ricardo Vásquez Varela's manual and taking into account that it is economically
feasible to carry them out.Tesi
Detection of growth-related QTLs in turbot (Scophtalmus maximux)
Background The turbot (Scophthalmus maximus) is a highly appreciated European aquaculture species. Growth related traits constitute the main goal of the ongoing genetic breeding programs of this species. The recent construction of a consensus linkage map in this species has allowed the selection of a panel of 100 homogeneously distributed markers covering the 26 linkage groups (LG) suitable for QTL search. In this study we addressed the detection of QTL with effect on body weight, length and Fulton's condition factor.
Results Eight families from two genetic breeding programs comprising 814 individuals were used to search for growth related QTL using the panel of microsatellites available for QTL screening. Two different approaches, maximum likelihood and regression interval mapping, were used in order to search for QTL. Up to eleven significant QTL were detected with both methods in at least one family: four for weight on LGs 5, 14, 15 and 16; five for length on LGs 5, 6, 12, 14 and 15; and two for Fulton's condition factor on LGs 3 and 16. In these LGs an association analysis was performed to ascertain the microsatellite marker with the highest apparent effect on the trait, in order to test the possibility of using them for marker assisted selection.
Conclusions The use of regression interval mapping and maximum likelihood methods for QTL detection provided consistent results in many cases, although the high variation observed for traits mean among families made it difficult to evaluate QTL effects. Finer mapping of detected QTL, looking for tightly linked markers to the causative mutation, and comparative genomics are suggested to deepen in the analysis of QTL in turbot so they can be applied in marker assisted selection programs
Current profiles and AC losses of a superconducting strip with elliptic cross-section in perpendicular magnetic field
The case of a hard type II superconductor in the form of strip with elliptic
cross-section when placed in transverse magnetic field is studied. We approach
the problem in two steps, both based on the critical-state model. First we
calculate numerically the penetrated current profiles that ensure complete
shielding in the interior, without assuming an a priori form for the profiles.
In the second step we introduce an analytical approximation that asumes that
the current profiles are ellipses. Expressions linking the sample magnetization
to the applied field are derived covering the whole range of applied fields.
The theoretical predictions are tested by the comparison with experimental data
for the imaginary part of AC susceptibility.Comment: 12 pages; 3 figure
