Effects of autochthonous Kluyveromyces lactis and commercial Enterococcus faecium adjunct cultures on the volatile profile and the sensory characteristics of short-ripened acid-curd Cebreiro cheese

Elaboráronse catro lotes de queixo tipo Cebreiro por duplicado a partir de leite pasterizado. Un lote control foi fabricado só cun cultivo iniciador comercial tipo O. Os outros tres lotes preparáronse co mesmo cultivo iniciador xunto con: (i) un cultivo comercial de Enterococcus faecium; (ii) un cultivo adxunto seleccionado de Kluyveromyces lactis, usado nunha etapa de premaduración do leite de elaboración; e (iii) unha combinación de ambos cultivos adxuntos. Os queixos elaborados co adxunto de lévedos caracterizáronse por valores máis altos de índices de proteolise xeral, pH e actividade da auga, e amosaron recontos de mesófilos totais e de bacterias lácticas polo menos 2 unidades logarítmicas maiores que os correspondentes aos lotes elaborados só con bacterias lácticas. Os perfís de compostos volátiles dos queixos elaborados con K. lactis distinguíronse polo seu alto contido en ésteres, alcohois de cadea ramificada, ácidos graxos, acetoína e 2-feniletanol. Estes lotes tiveron unha textura máis friable e adherente, e amosaron aromas diferenciados picante, a lévedo, alcohólico, acético e afroitado. Ademáis, a adición de enterococos semellou contribuir a acadar características sensoriais máis desexables. Os lotes fabricados con ambos cultivos adxuntos recibiron puntuacións máis altas nos parámetros preferencia de textura, intensidade de sabor, preferencia de aroma e sabor, e preferencia sensorial xeral. Os perfís sensoriais dos queixos elaborados con lévedos engadidos foron moi similares aos do queixo Cebreiro tradicional de leite cru de boa calidade sensorial.Xunta de Galici

Is different the behaviour of the professional football players heart rate in competition according to the tactical position of the player in the field?

[Resumen] El objetivo del estudio es el de profundizar en el conocimiento del comportamiento de la FC de los futbolistas profesionales en competición. Para ello se han recogido los valores que conforman el comportamiento de la FC de 6 futbolistas profesionales, con diferentes misiones en el equipo, en el transcurso de partidos de competición. Los resultados derivados del análisis de estos datos parecen indicar que existen diferencias significativas (<0,0001), entre las diferentes posiciones tácticas, tanto en términos de valores como en términos de variabilidad, así como en valores de percentiles, y de incrementos acusados, en los valores que conforman el comportamiento de la FC de los jugadores de la muestra. Estos resultados podrían apuntar hacia que el comportamiento de la FC parece algo directamente vinculado a la posición táctica ocupada y/o al perfil físico y fisiológico de cada futbolista

Water absorption behaviour and its effect on the mechanical properties of flax fibre reinforced bioepoxy composites

In the context of sustainable development, considerable interest is being shown in the use of natural fibres like as reinforcement in polymer composites and in the development of resins from renewable resources. This paper focus on eco-friendly and sustainable green composites manufacturing using Resin Transfer Moulding (RTM) process. Flax fibre reinforced bioepoxy composites at different weight fractions (40 and 55wt%) were prepared in order to study the effect of water absorption on their mechanical properties. Water absorption test was carried out by immersion specimens in water bath at room temperature for a time duration. The process of water absorption of these composites was found to approach Fickian diffusion behavior. Diffusion coefficients and maximum water uptake values were evaluated, the results showed that both increased with an increase in fibre content. Tensile and flexural properties of water immersed specimens were evaluated and compared to dry composite specimens. The results suggest that swelling of flax fibres due to water absorption can have positive effects on mechanical properties of the composite material. The results of this study showed that RTM process could be used to manufacture natural fibre reinforced composites with good mechanical properties even for potential applications in a humid environmentThis research is supported by the Spanish Ministerio de Ciencia e Innovacion, Projects PAID-05-11, DPI 2010-20333, and DPI 2013-44903-R-AR.Muñoz Dominguez, E.; García Manrique, JA.

Trends in prioritization of test cases : 2017-2019

A core task in software testing is the design of test suites. Large test suites may take too long to run frequently, and test case prioritization (TCP) techniques have been proposed to speed up the detection of faults. These techniques have become increasingly popular and the number of publications has grown in recent years. Surveys have covered most of the techniques, but the latest included only publications until 2016: interest is growing, and new proposals have been developed in the last three years. This paper aims to complete that survey by providing the latest developments in TCP to respond to this growing interest. Specifically we use the taxonomy proposed by Khatibsyarbin et al. on the most important publications from 2017 to the present day (2019). All in all, we found 320 papers in this period about test case prioritization. The results show that the main techniques used are search-, coverage- and similarity-based

The Development of Social Preferences

This paper examines how social preferences develop with age. This is done using a range of mini-dictator games from which we classify 665 subjects into a variety of behavioural types. We expand on previous developmental studies of pro-sociality and parochialism by analysing individuals aged 9–67, and by employing a cross country study where participants from Spain interact with participants from different ethnic groups (Arab, East Asian, Black and White) belonging to different countries (Morocco, China, Senegal and Spain). We identify a ‘U-shaped’ relationship between age and egalitarianism that had previously gone unnoticed, and appeared linear. An inverse “U-shaped” relationship is found to be true for altruism. A gender differential is found to emerge in teenage years, with females becoming less altruistic but more egalitarian than males. In contrast to the majority of previous economic studies of the development of social preferences, we report evidence of increased altruism, and decreased egalitarianism and spite expressed towards black individuals from Senegal

Feature Selection Using Genetic Algorithms for the Generation of a Recognition and Classification of Children Activities Model Using Environmental Sound

In the area of recognition and classification of children activities, numerous works have been proposed that make use of different data sources. In most of them, sensors embedded in children’s garments are used. In this work, the use of environmental sound data is proposed to generate a recognition and classification of children activities model through automatic learning techniques, optimized for application on mobile devices. Initially, the use of a genetic algorithm for a feature selection is presented, reducing the original size of the dataset used, an important aspect when working with the limited resources of a mobile device. For the evaluation of this process, five different classification methods are applied, k-nearest neighbor (k-NN), nearest centroid (NC), artificial neural networks (ANNs), random forest (RF), and recursive partitioning trees (Rpart). Finally, a comparison of the models obtained, based on the accuracy, is performed, in order to identify the classification method that presents the best performance in the development of a model that allows the identification of children activity based on audio signals. According to the results, the best performance is presented by the five-feature model developed through RF, obtaining an accuracy of 0.92, which allows to conclude that it is possible to automatically classify children activity based on a reduced set of features with significant accuracy.In the area of recognition and classification of children activities, numerous works have been proposed that make use of different data sources.

Estimation of Indoor Location Through Magnetic Field Data: An Approach Based On Convolutional Neural Networks

Estimation of indoor location represents an interesting research topic since it is a main contextual variable for location bases services (LBS), eHealth applications and commercial systems, among others. For instance, hospitals require location data of their employees, as well as the location of their patients to offer services based on these locations at the correct moments of their needs. Several approaches have been proposed to tackle this problem using different types of artificial or natural signals (ie, wifi, bluetooth, rfid, sound, movement, etc.). In this work, it is proposed the development of an indoor location estimator system, relying in the data provided by the magnetic field of the rooms, which has been demonstrated that is unique and quasi-stationary. For this purpose, it is analyzed the spectral evolution of the magnetic field data viewed as a bidimensional heatmap, avoiding temporal dependencies. A Fourier transform is applied to the bidimensional heatmap of the magnetic field data to feed a convolutional neural network (CNN) to generate a model to estimate the user’s location in a building. The evaluation of the CNN model to deploy an indoor location system (ILS) is done through measuring the Receiver Operating Characteristic (ROC) curve to observe the behavior in terms of sensitivity and specificity. Our experiments achieve a 0.99 Area Under the Curve (AUC) in the training data-set and a 0.74 in a total blind data set.Estimation of indoor location represents an interesting research topic since it is a main contextual variable for location bases services (LBS), eHealth applications and commercial systems, among others.

Virtual reality exercise intradialysis to improve physical function: A feasibility randomized trial

[EN] Objective The main objective of this investigation was to assess feasibility of conducting a future RCT with an intradialysis non-immersive virtual reality exercise intervention. The secondary aim was to explore the impact of either conventional or VR exercise on physical function. Design Feasibility randomized trial. Participants Eighteen subjects who participated in a 16-week intradialysis combined exercise program. Interventions The program lasted four additional weeks of either combined exercise or virtual reality exercise. Main outcome measures Physical function was measured through several reliable tests (sit-to-stand-to-sit tests 10 and 60, gait speed, one-leg heel-rise tests, and 6-minute walk test) at baseline, after 16 weeks of intradialysis combined exercise and by the end of four additional weeks of exercise. Adherence to the exercise programs was registered. Results There was a significant time effect, so that physical function improved in both groups. By the end of the 20 weeks, function improved as measured through the sit-to-stand-to-sit tests 10 and 60, gait speed, one-leg heel-rise left leg, and the 6-minute walk test. Changes that did not occur due to error in the test were seen after 20 weeks were achieved in the sit-to-stand-to-sit test 60, gait speed, one-leg heel-rise test for the left leg, and 6-minute walking test. Conclusion Virtual reality was a feasible intervention. Both interventions improved physical function. Adherence was not significantly different between groups.Universidad Cardenal Herrera-CEU, CEU Universities, Valencia, Spain, Grant/Award Number: Consolidacion de Indicadores CEU-UCH 2016-2017/ISegura-Orti, E.; Perez-Dominguez, B.; Ortega-Pérez De Villar, L.; Melendez-Oliva, E.; Martínez-Gramaje, J.; García-Maset, R.; Gil-Gómez, J.

Hemodynamic performance of different stent strategies for coronary bifurcations. Evaluation with a mathematical model

Purpose: Best percutaneous treatment strategy for lesions in coronary bifurcations is an ongoing subject of debate. There is limited data that analyses the effect of the different bifurcation strategies on coronary flow. Our aim is to evaluate the influence of different bifurcation stenting strategies on hemodynamic parameters, both in the main vessel (MV) and side branch (SB)
