A 2-set-up Routley-Meyer Semantics for the 4-valued Relevant Logic E4

The logic BN4 can be considered as the 4-valued logic of the relevant conditional and the logic E4, as the 4-valued logic of (relevant) entailment. The aim of this paper is to endow E4 with a 2-set-up Routley-Meyer semantics. It is proved that E4 is strongly sound and complete w.r.t. this semantics

Lisístrata. Proyecto de intervención sobre los estereotipos de género en adolescentes a través del arte

[ES] Los estereotipos de género son creencias y pautas sociales que las personas interiorizan y asimilan desde el primer momento en el que nacen. Estas creencias pueden desarrollar una serie de aspectos discriminatorios en cuanto a la figura de la mujer y del hombre y que en ocasiones generan desigualdad en algunos ámbitos de la vida cotidiana. Por ello, es importante trabajar estas creencias para detectarlas y eliminarlas en cualquier etapa de la vida humana. En este caso se pretende crear una propuesta de intervención sobre los estereotipos de género dirigido a la etapa de la adolescencia. Etapa muy compleja donde estos jóvenes experimentan unas series de cambios a nivel personal y físico que si se gestionan de manera incorrecta pueden generar complicaciones futuras como es el caso de la violencia de género en las relaciones de parejas. Por esta razón, se ha diseñado una propuesta de intervención educativa, llamada Lisístrata, dirigida a adolescentes para trabajar los estereotipos de género a través del arte como instrumento educativo de cambio social en el instituto de educación secundaria obligatoria del municipio de Fuentesaúco. De esta manera se pretende eliminar estas creencias interiorizadas por diversos agentes socializadores y desarrollar atributos y características propias libres de estereotipos de género.[EN] Gender stereotypes are beliefs and social guidelines that people internalise and assimilate from the momento they are born. These beliefs can develop a series of discriminatory aspects regarding the figure of women and men that sometines generate inequality in some áreas of daily life. It is therefore important to work on these beliefs in order to detect and eliminate them at any stage of human life. In this case, the aim is to create an intervention proposal on gender stereotypes aimed at the adolescent stage. This is a very complex stage where these young people experience a series of personal and physical changes that, if managed incorrectly, can generate future complications such as gender violence in relationships. For this reason, an educational intervention proposal has been designed, called Lysistrata, aimed at adolescents to work on gender stereotypes through art as an educational tool for social change in the compulsory secondary school of the municipality of Fuentesauco. In this way, the aim is to eliminate these beliefs internalised by various socialising agents and to develop attriutes and characteristics free of gender stereotypes

The class of all 3-valued natural conditional variants of RM3 that are Plumwood Algebras

Valerie Plumwood introduced in "Some false laws of logic" a series of arguments on how the rules Exported Syllogism, Disjunctive Syllogism, Commutation, and Exportation are not acceptable. Based on this we define the class of Plumwood algebras - logical matrices that do not verify any of these theses. Afterwards we provide conditional variants of the characteristic matrix of the logic RM3 that are also Plumwood algebras. These matrices are given an axiomatization based on First Degree Entailment and are endowed with Belnap-Dunn Semantics. Finally we provide results of Soundness and Completeness in the strong sense for each of the defined variants

Modeling °Brix and pH in wine grapes from satellite images in Colchagua valley, Chile

[EN] In order to monitor the ripeness and composition of wine grape berries and establish an optimal harvest date, the determination of °Brix and pH is vital. This research includes the study of two wine grapes harvests seasons of Cabernet Sauvignon variety: 2017 and 2018. Field data was periodically taken, allowing to follow the phenological state of the vine. Incorporating technological solutions to the fruit sampling process, such as Sentinel-2 images, permits optimizing a handcrafted procedure and gives the possibility of having a more detailed view of the plots. From the images, 12 variables were obtained, composed of 8 bands and 4 spectral indices, which were related to variables extracted from field samples. The °Brix modeling presents an R2 of 69% and 73% in the 2017 and 2018 seasons, respectively. In pH modeling, the 2017 season had low R2 results, reaching 43%, which then improves considerably in the 2018 season, reaching 63,8%. By choosing a model that allows defining the variability of the plot and the possible early or late ripening areas of the vineyard, is not only very useful but also very valuable to reach a constant improvement in production and hence in the wine quality.[ES] Con el fin de monitorear la madurez y composición de las bayas de uva vinífera y determinar una fecha óptima de cosecha, es vital la determinación de °Brix y pH. Esta investigación comprende el estudio de dos temporadas de cosecha de uva vinífera de variedad Cabernet Sauvignon: 2017 y 2018. Periodo en el cual se tomaron periódicamente datos de campo que permitieron seguir el estado fenológico de la vid hasta el momento de la cosecha y posterior vinificación. Incorporar soluciones tecnológicas, como el uso de imágenes satelitales, en este caso Sentinel-2, al proceso de muestreo de fruta, permite optimizar un proceso artesanal, dando la posibilidad de tener una visión más detallada del cuartel, lo que hace más eficiente el trabajo de terreno. Desde las imágenes se obtuvieron 12 variables compuestas por 8 bandas y 4 indicadores (NDVI, NDMI, Clorofila y GNDVI) que se relacionaron con variables extraídas de muestreos de campo. Con dichos datos se seleccionó el mejor modelo de regresión lineal múltiple, utilizando 3 variables para predecir °Brix y pH. La modelación de °Brix presenta un coeficiente de determinación R2 de 69% y 73% en las temporadas 2017 y 2018, respectivamente. En el caso de la modelación de pH, la temporada 2017 tiene bajos resultados de R2, alcanzando un 43%, el cual mejora considerablemente en la temporada 2018, alcanzando un 63.8%. Determinar un modelo que permita definir la variabilidad de la parcela y, por tanto, las posibles zonas de maduración temprana o tardía del viñedo, es de gran utilidad para concretar una mejora en la producción y por ende en la calidad del vino.Fredes, S.; Ruiz Fernández, LÁ.; Recio Recio, JA.

Polymeric stationary phases based on poly(butylene terephthalate)and poly(4-vinylpirydine) in the analysis of polyphenols usingsupercritical fluid chromatography. Application to bee pollen

Producción CientíficaTwo new polymer-based stationary phases; DCpak PBT (poly(butylene terephthalate)) and DCpak P4VP(poly(4-vinylpirydine)) were evaluated for the analysis of polyphenols using supercritical fluid chro-matography (SFC). The compounds studied included phenolic acids and flavonoids. The different variablesthat influence the chromatographic separation, such as type and percentage of organic modifier, additive,pressure and temperature were examined. Using the DCpak P4VP column the retention was exception-ally high, obtaining better results with the DCpak PBT column. The separation of nine polyphenols wasachieved using a gradient of modifier (methanol with 0.1% trifluoroacetic acid) from 5 to 50%, a pressureof 150 bar, a temperature of 35◦C and a flow-rate of 2 mL/min. The use of additives was necessary in orderto obtain good peak shapes and efficiencies, achieving the best results with trifluoroacetic acid. LODs andLOQs values were lower than 5 g/mL in all the cases; meanwhile, the %RSD values for method repeatabil-ity and inter-day reproducibility were lower than 3% and 10% respectively. Finally, the proposed methodwas successfully applied to the analysis of polyphenols in commercial bee pollen; four compounds,namely cinnamic acid, p-coumaric acid, catechin and quercetin were identified and quantified

Relational semantics for the 4-valued relevant logics BN4 and E4

The logic BN4 was defined by R.T. Brady in 1982. It can be considered as the 4-valued logic of the relevant conditional. E4 is a variant of BN4 that can be considered as the 4-valued logic of (relevant) entailment. The aim of this paper is to define reduced general Routley-Meyer semantics for BN4 and E4. It is proved that BN4 and E4 are strongly sound and complete w.r.t. their respective semantics

Clinical characterization and factors associated with quality of life in Long COVID patients: Secondary data analysis from a randomized clinical trial

Background: Long COVID patients suffer a negative impact on their quality of life, as well as their functioning, productivity or socialization. There is a need to better understand the individual experience and circumstances surrounding these patients. Objective: To characterize clinical picture of Long COVID patients and to identify factors associated with quality of life. Methods: A secondary data analysis from a randomized clinical trial (RCT) was carried out with 100 Long COVID patients treated by Primary Health Care and residents in the territory of Aragon (northeast of Spain). The main variable of the study was quality of life, evaluated using the SF-36 Questionnaire, in relation to socio-demographic and clinical variables. In addition, ten validated scales were used that contemplated their cognitive, affective, functional and social status, as well as personal constructs. Correlation statistics and linear regression model were calculated. Results: Long COVID patients suffer a decrease in their levels of physical and mental health. On the one hand, the higher number of persistent symptoms (b = -0.900, p = 0.008), worse physical functioning (b = 1.587, p = 0.002) and sleep quality (b = -0.538, p = 0.035) are predictors of worse quality of life, physical subscale. On the other hand, higher educational level (b = 13.167, p = 0.017), lower number of persistent symptoms (b = -0.621, p = 0.057) and higher affective affectation (b = -1.402, p<0.001) are predictors of worse quality of life, mental subscale. Conclusion: It is necessary to design rehabilitation programs that consider both the physical and mental health of these patients, thus obtaining an improvement in their quality of life

Candida y candidiasis invasora : estudio de la actividad antifúngica in vitro de arasertaconazol frente a cepas clínicas de Candida y caracterización molecular de cepas productoras de candidemia relacionada con el catéter

La infección por Candida es un problema de salud pública que abarca desde alteraciones de la flora normal hasta infecciones sistémicas graves en pacientes inmunosuprimidos o portadores de catéteres intravasculares. El tratamiento de la candidiasis sistémica se basa en la administración de un tratamiento antifúngico correcto junto con la retirada del catéter intravascular, si se demuestra que éste es el origen de la infección. El aumento de cepas portadoras de resistencia antifúngica hace necesario el desarrollo de nuevos fármacos para tratar la candidiasis; uno de los fármacos más novedosos es el arasertaconazol nitrato. En este proyecto se estudió la actividad antifúngica de arasertaconazol frente a aislados clínicos de Candida, así como el establecimiento de rangos de CMI aceptables con cepas de colección ATCC según los estándares establecidos en el documento CLSI M27-A3. Por otra parte, para estudiar si el catéter era el origen de la candidemia, se estudió la presencia de genotipos idénticos en muestras de sangre y catéter aislados simultáneamente en pacientes con candidemia y portadores de catéter intravascular. El otro objetivo del proyecto fue recoger prospectivamente y genotipar mediante el análisis de microsatélites las cepas mencionadas pertenecientes a las especies C. albicans y C. parapsilosi

Plan de Empresa: Creación de una residencia de estudiantes Erasmus

En este trabajo de fin de grado se ha desarrollado un plan de empresa consistente en el análisis para la creación de una residencia universitaria en Zaragoza, centrada en los estudiantes Erasmus, algo de lo que nuestra ciudad carece, y que representa una oportunidad, tanto a nivel de negocio como a la hora de aportar un valor añadido a nuestra Universidad, que la haga más atractiva a los estudiantes que quieran acudir a estudiar su programa Erasmus y que en la actualidad deben o bien alquilar un piso compartido o vivir en una residencia con una mayoría de estudiantes nacionales. La idea del proyecto nació después de mi experiencia como estudiante Erasmus en Berlín, viviendo durante más de 10 meses en una residencia como la que pretendo emular en mi plan de empresa y visitando varias residencias más en múltiples viajes, dándome cuenta que existían una serie de características comunes a todas estas residencias en Europa y que era la forma de alojamiento más demandada por los estudiantes. Se trata, en definitiva, de un proyecto que viene a cubrir una necesidad existente y que posibilitaría que la búsqueda de alojamiento no suponga un impedimento para los estudiantes internacionales a la hora de seleccionar Zaragoza como destino para realizar su programa Erasmus<br /

Comparison of three short-course rifamycin-based regimens for the prevention of tuberculosis in patients with end-stage kidney disease: Study protocol for a randomised clinical trial (RIFAKiD-TB trial)

Background and purpose Screening for and treatment of latent tuberculosis (TB) in patients with end-stage kidney disease (ESKD) are recommended. However, there is limited evidence on safety and treatment completion in this population. The objective of the study is to evaluate three short-course rifamycin-based regimens for the treatment of latent TB in ESKD patients. Methods Study design and setting. This is a prospective, open label, randomized clinical trial, that will be conducted at seven teaching hospitals in Spain. Study population, randomization, and interventions. Consecutive adult patients with ESKD requiring treatment for a latent TB infection will be randomly allocated (1:1:1) to receive one of the three treatment regimens of the study: three months of daily isoniazid plus rifampicin (3HR); three months of once-weekly isoniazid plus rifapentine (3HP); or four months of daily rifampicin (4R). Participants will be followed regularly through pre-established visits and a blood test schedule from enrolment to a month after finishing the assigned treatment. Outcomes. The primary outcome will be treatment completion, while the secondary outcomes will be discontinuation of the assigned treatment due to adverse events, related or unrelated to the study treatment; definitive discontinuation of the assigned treatment because of adverse events related to the treatment of the study, and death. Sample size. Two hundred and twenty-five subjects (75 per arm) will be enrolled, which will enable the demonstration, if it exists, of an increase of 0.16 in treatment completion rates either in the 3HP or 4R arm with respect to the 3HR arm. Discussion Results of this clinical trial will contribute to evidence-based recommendations on the management of latent TB infection in ESKD patients
