Notes on the liturgy in Pamplona cathedral. Rites, magnificence and power
Get PDFLas formas y tipologías artísticas, la música y los ritos solemnes de una liturgia, especialmente
cuidada, han distinguido, secularmente, a nuestras catedrales. De modo muy especial en las fiestas, en donde se han venido fundiendo lo solemne (rito), lo artístico (belleza) y lo extraordinario
(infrecuente). El ejemplo de la catedral de Pamplona y su ceremonial, a lo largo de los siglos,
viene a ejemplificar la importancia de los mencionados elementos, en una ciudad que ostentaba
la capitalidad del virreinato navarro, en la que los elementos de poder y representación cobraban
un especial significado.The forms and artistic typologies, the music and the solemn rites of a liturgy, especially careful,
have distinguished, secularly, our cathedrals. In a very special way in the festivals, where the
solemn (rite), the artistic (beauty) and the extraordinary (infrequent) have been merging. The
example of the cathedral of Pamplona and its ceremonial, throughout the centuries, comes to
exemplify the importance of the aforementioned elements, in a city that held the capital status of
the Navarrese viceroyalty, in which the elements of power and representation took on a special
meaning
A stepped tabu search method for the clique partitioning problem
No full textGiven an undirected graph, a clique is a subset of vertices in which the induced subgraph is complete; that is, all pairs of vertices
of this subset are adjacent. Clique problems in graphs are very important due to their numerous applications. One of these
problems is the clique partitioning problem (CPP), which consists of dividing the set of vertices of a graph into the smallest
number of cliques possible. The CPP is an NP-hard problem with many application fields (timetabling, manufacturing, scheduling, telecommunications, etc.). Despite its great applicability, few recent studies have focused on proposing specific resolution
methods for the CPP. This article presents a resolution method that combines multistart strategies with tabu search. The most
novel characteristic of our method is that it allows unfeasible solutions to be visited, which facilitates exploration of the solution
space. The computational tests show that our method performs better than previous methods proposed for this problem. In fact,
our method strictly improves the results of these methods in most of the instances considered while requiring less computation
time.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

“Back‐to‐Front” Indole and Carbazole Synthesis from N,N‐Bis‐(2‐bromoallyl)amines by Combining Carbolithiation Reactions with Gold‐Catalysis
Get PDFThe combination of organolithium chemistry with gold catalysis has enabled the development of a
synthetic strategy for accessing polysubstituted indoles and carbazoles from readily available starting materials.
This method is based on a “back-to-front” approach from ketopyrroles, generated by intramolecular
carbolithiation of N,N-bis-(2-lithioallyl)amines that evolve into 3,4-bis(lithiomethyl)dihydropyrrole intermediates capable of reacting with carboxylic esters and Weinreb amides. These ketopyrroles have demonstrated to
be excellent precursors of mono or bis(alkynols)pyrroles that, under gold-catalysis, experience a
benzannulation reaction providing access to regioselectively substituted indoles or carbazoles.We gratefully acknowledge Ministerio de Ciencia e Innovación MCIN/AEI/10.13039/501100011033 (PID2020-115789GBC21), and Junta de Castilla y León and FEDER (BU049P20) for financial support.

Propuesta de intervención educativa para la inserción laboral de personas con discapacidad mediante impresoras 3D
No full textComunicación presentada en: VI Congreso Internacional sobre Innovación Pedagógica y Praxis Educativa (INNOVAGOGÍA 2022), celebrado online, del 25 al 27 de mayo de 2022.Uno de los principales retos actuales en el mundo de la discapacidad es asegurar su inclusión laboral. En cuanto a la situación sociolaboral de las personas con discapacidad existe una baja participación, pero está demostrado que cuanta mayor cualificación posean, más posibilidades de acceder al mercado laboral tienen. El objetivo de la presente comunicación es el desarrollo de una propuesta educativa para la inserción laboral para personas con discapacidad mediante la impresión 3D. De esta forma se contribuye a la creación de una sociedad más inclusiva y con menos prejuicios. Existen diversas modalidades de inserción laboral en el empleo ordinario con apoyo, en las cuales se brinda a las personas con discapacidad los mismos derechos de acceso al mundo laboral. A continuación, se describe una propuesta a través del empleo con apoyo para fomentar la autonomía de las personas con discapacidad. La metodología empleada se basa en un sistema estructurado de empleo con apoyo, cuyo objetivo es la incorporación laboral. Después de realizar el acompañamiento y preparación de una persona con discapacidad en una empresa de impresión 3D se observa la necesidad de elaborar un manual de impresión 3D adaptado para personas con discapacidad
Simultaneous addition of slag binder, recycled concrete aggregate and sustainable powders to self-compacting concrete: a synergistic mechanical-property approach
Get PDFThe behavior of Self-Compacting Concrete (SCC) is very sensitive to the use of by-products
in replacement of conventional cement or finer aggregate fractions. The high proportions
of these raw materials in SCC can in great part explain this performance. 18 SCC mixes of
slump-flow class SF3 were prepared for a thorough evaluation of different sustainable
materials and for the prediction of their effects as binder or fine/powder aggregate on the
mechanical properties of SCC. The mixes incorporated 100% coarse Recycled Concrete
Aggregate (RCA); different amounts (0%, 50% or 100%) of fine RCA; CEM I ordinary Portland
cement and CEM III/A (with 45% ground granulated blast furnace slag); and more sustainable powders compared to conventional limestone filler <0.063 mm (such as limestone
powder 0/0.5 mm and RCA powder 0/0.5 mm). Flowability, hardened density, strength
under compression, tensile and bending stresses and modulus of elasticity were all studied. The addition of 50% fine RCA yielded an SCC of adequate strength, stiffness and
flowability. SCC manufactured with limestone powder 0/0.5 mm showed the best overall
performance, while SCC behavior was improved when adding CEM III/A by adjusting the
mix composition. The experimental results of all the mechanical properties were
compared with the values predicted by the compressive-strength-based formulas from the
European and USA standards. Overall, the values resulting from those expressions overestimated all the mechanical properties. Therefore, since all these properties followed
the same simple-regression trend, a statistical analysis was performed to develop a global
model capable of accurately predicting them all.The authors wish to express their gratitude for funding this research work to: the Spanish Ministry of Universities, MICINN, AEI, EU, and ERDF [PID2020-113837RB-I00; 10.13039/501100011033; FPU17/03374; PRX21/00007]; the Junta de Castilla y León (Regional Government) and ERDF [UIC-231, BU119P17]; and the University of Burgos [SUCONS, Y135.GI] and the University of Padova
Ensuring analytical quality in regulated markets through multivariate, multiway and DoE strategies
Get PDFAl abordar un problema de determinación analítica, han de tenerse en cuenta tanto aspectos
fisicoquímicos como características instrumentales de cara a desarrollar un procedimiento de
análisis válido. Estas variables no son realmente independientes unas de otras: una estrategia
multivariante donde la correlación y la covarianza juegan un papel esencial refuerza el camino al
éxito, como evidencia esta tesis doctoral. Herramientas quimiométricas multivariantes como la
regresión PLS, la estimación de la capacidad de detección multivariante, las funciones de
deseabilidad y el diseño de experimentos, junto con técnicas multivía como las descomposiciones
PARAFAC y PARAFAC2 demuestran a lo largo de esta tesis su idoneidad para aumentar la
exactitud, sensibilidad, especificidad y robustez de procedimientos multirresiduo basados en
espectroscopía o en cromatografía acoplada a espectrometría de masas destinados a la
determinación de la composición de alimentos (Queso Zamorano) y la detección de distintas
familias químicas (tranquilizantes, bisfenoles y plastificantes) en alimentos (carne, productos
lácteos mediante simulantes alimentarios) y en productos en contacto con alimentos (vajilla, vasos
y tetinas infantiles). En concreto, la especificidad requerida para todo procedimiento analítico
diseñado para sustancias altamente reguladas es perfectamente asegurada mediante el uso de
descomposiciones PARAFAC. Dicha especificidad, basada en la denominada ventaja de segundo
orden que presenta, por ejemplo, la cromatografía acoplada a espectrometría de masas, puede no
alcanzarse si se siguen metodologías tradicionales cuando no es posible conseguir una resolución
de picos completa o existen interferentes en la muestra.
Por otro lado, esta tesis revela la importancia de la elección de la variable respuesta en un estudio
analítico, hecho clave en el proceso de desarrollo de todo Espacio de Diseño Analítico, en
consonancia con las recientes aproximaciones de autoridades regulatorias y de organismos
internacionales para trasladar el paradigma de la Calidad por el Diseño (Quality by Design, QbD) al
laboratorio.When facing an analytical determination problem, both physicochemical and instrumental
features should be considered so as to develop a valid analytical method. All those variables are
not actually independent from each other, so a multivariate framework where correlation and
covariance play a key role strengthens the way to that success, as every study in this doctoral
thesis consistently shows. In this sense, multivariate chemometric tools such as Partial Least
Squares regression, detection capability estimation based on multivariate curves, D-optimal
designs, both full and fractional factorial designs and desirability functions, together with
multiway techniques like PARAFAC and PARAFAC2 decomposition have proven their
suitability in enhancing accuracy, sensitivity, specificity and robustness of both spectroscopy- and
chromatography-mass-spectrometry-based multiresidue procedures on different chemical families
(tranquillizers, bisphenols and plasticizers), foodstuffs (Queso Zamorano, meat) and migrating food
materials (tableware, glasses and infant dummies). In particular, the specificity required for every
analytical method and specifically for those dealing with regulated substances has been fully
ensured by the use of PARAFAC decompositions on three-way tensors; that specificity, which is
founded on its so-called second-order advantage, can fail if traditional methodologies are followed
whenever a poor resolution is achieved or whether interferents are present in the sample. The
importance of a wise selection of the response variable for an analytical study has also been
revealed, which should be kept in mind to succeed in the statement of any analytical Design
Space, as the recent approaches to extend the Quality by Design paradigm into the analytical
laboratory claim.agradecer el apoyo

Medición de la responsabilidad social universitaria en el Ecuador: caso Universidad Técnica Estatal de Quevedo
No full textLa presente investigación tiene como objetivo proponer un modelo de medición de
responsabilidad social universitaria. La muestra estuvo conformada por los administrativos,
docentes y estudiantes de la Universidad Técnica Estatal de Quevedo (UTEQ), aplicó un
cuestionario adaptado del desarrollado por URSULA (Vallaeys, 2021). Así mismo, se utilizó
la matriz de autodiagnóstico RSU – URSULA (Vallaeys et al., 2021) para obtener
información de las autoridades y directivos de la UTEQ. Ambos instrumentos miden las 12
metas y 66 indicadores del modelo URSULA, evalúan las cuatro dimensiones de la
responsabilidad social universitaria: gestión organizacional, formación, cognición y
participación social. Los resultados muestran una alta fiabilidad del instrumento de medición.
Los stakeholders internos señalan que la mayoría de los indicadores de las metas muestran
un desempeño medio. Adicionalmente, la prueba U de Mann-Whitney identificó la existencia
de diferencias significativas en el indicador global RSU entre los estudiantes de las diferentes
facultades.The objective of this research is to propose a model for measuring university social
responsibility. For this purpose, a survey was applied to workers, teachers and students
of the State Technical University of Quevedo (UTEQ), through a questionnaire adapted
from the one developed by URSULA (Vallaeys, 2021). Likewise, the USR-URSULA
self-diagnosis matrix (Vallaeys et al., 2021) was used to collect information from the
authorities and directors of the UTEQ. Both instruments measure the 12 goals of the
URSULA model, which assess the four dimensions of university social responsibility:
organizational management, education, cognition and social participation. In the case of
workers, the means were used for the evaluations of the three goals of the organizational
management dimension. For the analysis of the goals from the perspective of teachers
and students, a factorial analysis of principal components was applied. The results were
used to calculate indicators for each of the goals of the model and to calculate a global
indicator of university social responsibility. The results show a high reliability of the
measuring instrument. The descriptive analysis of the indicators showed that there is a
discrepancy between the diagnosis made by the authorities and managers and the
perspective of the workers, teachers and students. Additionally, the Mann-Whitney U test
identified the existence of significant differences in the global indicator of university
social responsibility
From Classical to Advanced Use of Polymers in Food and Beverage Applications
Get PDFPolymers are extensively used in food and beverage packaging to shield against contaminants and external damage due to their barrier properties, protecting the goods inside and reducing waste. However, current trends in polymers for food, water, and beverage applications are moving forward into the design and preparation of advanced polymers, which can act as active packaging, bearing active ingredients in their formulation, or controlling the head-space composition to extend the shelf-life of the goods inside. In addition, polymers can serve as sensory polymers to detect and indicate the presence of target species, including contaminants of food quality indicators, or even to remove or separate target species for later quantification. Polymers are nowadays essential materials for both food safety and the extension of food shelf-life, which are key goals of the food industry, and the irruption of smart materials is opening new opportunities for going even further in these goals. This review describes the state of the art following the last 10 years of research within the field of food and beverage polymer’s applications, covering present applications, perspectives, and concerns related to waste generation and the circular economy.This work was supported by the Regional Government of Castilla y León (Junta de Castilla y León) and by the Ministry of Science and Innovation MICIN and the European Union NextGeneration EU PRTR.
