Cartagena sociology of leisure in the late nineteenth and early twentieth centuries: Club de Regatas Icue the Bathrooms

[SPA] Un acercamiento a la cultura del ocio en Cartagena a fines del XIX y principios del XX; nos sitúa ante un variopinto sociológico representativo de la sociedad plural, diversa y claramente estratificada que entonces existía. Algunas prácticas de esparcimiento simbolizaban diferencias de status, por las que se alardeaba del lugar que cada individuo ocupaba en la estructura social. Sirvan como ejemplo, las actividades que se organizaban en el Club de Regatas, desde los baños en la patacha a los bailoteos de los que hacían gala los ecos de sociedad. Sin embargo, había otros espacios y hábitos de recreo que servían de nexo de cohesión ciudadana, con independencia de la condición o clase de procedencia. Tal efecto producían los paseos por el muelle, los espectáculos ambulantes, los juegos florales, las veladas marítimas, la feria, los desfiles militares y la música de Infantería; atractivo no solo para los residentes de la portuaria sino también reclamo de foráneos. En un ambiente de progreso que llegaba de la mano del comercio, la industria y la minería, la fiesta se vivía con alegría. La dirección que iba tomando la vida socio-cultural de la ciudad estaba en gran parte al timón de la burguesía; principal favorecedora del florecimiento de una diversión cultivada que llevaba pareja la creación de nuevos espacios de ocio y espectáculos. El desajuste entre las distintas clases sociales se hacía notar en las maneras de diversión, costumbres y hábitos de esparcimiento. Pese a todo, la alegría se expandía por las calles cuando llegaban las festividades de verano, carnaval y Semana Santa.

On the time-consistent stochastic dominance risk averse measure for tactical supply chain planning under uncertainty

In this work a modeling framework and a solution approach have been presented for a multi-period stochastic mixed 0–1 problem arising in tactical supply chain planning (TSCP). A multistage scenario tree based scheme is used to represent the parameters’ uncertainty and develop the related Deterministic Equivalent Model. A cost risk reduction is performed by using a new time-consistent risk averse measure. Given the dimensions of this problem in real-life applications, a decomposition approach is proposed. It is based on stochastic dynamic programming (SDP). The computational experience is twofold, a compar- ison is performed between the plain use of a current state-of-the-art mixed integer optimization solver and the proposed SDP decomposition approach considering the risk neutral version of the model as the subject for the benchmarking. The add-value of the new risk averse strategy is confirmed by the compu- tational results that are obtained using SDP for both versions of the TSCP model, namely, risk neutral and risk averse.The authors would like to thank to the two anonymous review- ers for their help on clarifying some concepts presented in the manuscript and strongly improving its presentatio

Online games for the teaching of mathematics

In this article we present a didactic experience developed by the GIE (Group of Educational Innovation) “Pensamiento Matemático” of the Polytechnics University of Madrid (UPM), in order to bring secondary students and university students closer to Mathematics. It deals with the development of a virtual board game called Mate-trivial. The mechanics of the game is to win points by going around the board which consists of four types of squares identified by colours: “Statistics and Probability”, “Calculus and Analysis”, “Algebra and Geometry” and “Arithmetic and Number Theory ”. When landing on a square, a question of its category is set out: a correct answer wins 200 points, if wrong it loses 100 points, and not answering causes no effect on the points, but all the same, two minutes out of the 20 minutes that each game lasts are lost. For the game to be over it is necessary, before those 20 minutes run out, to reach the central square and succeed in the final task: four chained questions, one of each type, which must be all answered correctly. It is possible to choose between two levels to play: Level 1, for pre-university students and Level 2 for university students. A prototype of the game is available at the website “Aula de Pensamiento Matemático” developed by the GIE: http://innovacioneducativa.upm.es/pensamientomatematico/. This activity lies within a set of didactic actions which the GIE is developing in the framework of the project “Collaborative Strategies between University and Secondary School Education for the teaching and learning of Mathematics: An Application to solve problems while playing”, a transversal project financed by the UPM

Applications of Voltammetric Analysis to Wine Products

Wine contains polyphenols that are responsible for its quality. Moreover, phenolic compounds have antioxidant properties and benefits on human health. Cyclic voltammetry (CV) was the first electrochemical method used for polyphenols characterization and determination of polyphenols content in wine products. Electrochemical behaviour of standard solutions of phenolic compounds has been investigated and evaluated the importance of the phenolic concentration and pH. The electrochemical parameters extracted from the voltammograms have been correlated with the antioxidant potential in wine products. In addition, CV allowed establishing differences in the antioxidant activity of wines with different addition of grape seeds. In winemaking by-products, different Ipa and Q500 values were found depending on the state of maturation of the grape pomace. On the other hand, the total flavonoids and phenolic acids contents were significantly correlated to the electrochemical parameters. Differences for the electrochemical parameters were found between by-products, being pomace and seeds which presented the greatest values of Q500. Simple regression analyses showed that voltammetric parameters are correlated to their values of lipid peroxidation inhibition by thiobarbituric acid reactive substances method. Our results open the possibility of CV as a promising technique to estimate the global antioxidant potential of wine products rich in phenolic compounds

RESUMENEste trabajo tiene como objetivo analizar la influencia que la internacionalización puede tener sobre la adopción de una estrategia medioambiental más proactiva por parte de las empresas. Para conseguir este objetivo realizamos 103 entrevistas personales a los directores generales de empresas exportadoras españolas pertenecientes al sector de la alimentación. Nuestros resultados muestran que un alto grado de diversificación internacional favorece el desarrollo de una estrategia medioambiental más proactiva. Además, la experiencia internacional de las empresas contribuye también a la adquisición de capacidades medioambientales valiosas. Por tanto, la internacionalización permite a las empresas desarrollar una estrategia más avanzada en gestión medioambiental. Finalmente, recogemos una serie de implicaciones de carácter práctico para directivos y reguladores públicos.ABSTRACTWe analyze the influence of the firms' internationalization process of firms on the adoption of a proactive environmental strategy. Using direct interviews with the CEOs of 103 export Spanish firms from the food industry, we show that a high degree of international diversification encourages these firms to take advantage of different environmental competitive advantages from the different regions where they operate. In addition, firms' international experience contributes to acquiring valuable environmental capabilities. Thus, our results support that internationalization leads firms to develop an advanced posture to environmental issues and adopt a proactive environmental strategy. Our paper discusses implications for managers and policy-makers

Lucha frente a la Varroosis en colmenas Layens

111 páginas, 89 figuras, 17 tablas . -- Con la colaboración de: Mª Sonia Rodríguez Cruz, José Manuel Ordax de Castro, Raquel Arroyo Palomares, Yolanda Picó García, Juan Manuel Andrés Sánchez, Francisco Javier Fernández Santiago, Miguel Ángel Santos Oliva, Fernando Sánchez-Montejo Álvarez y Aurelio Pérez Sánchez.Actualmente la varroosis es el principal problema de la apicultura a nivel sanitario, tratándose de la enfermedad de las colonias de abejas más importante, y la única que obliga a realizar un tratamiento sistemático de la colmena para que los efectos del parásito no influyan negativamente en el rendimiento o incluso la viabilidad de la misma. Como consecuencia de la importancia de la actividad apícola en Castilla y León y dada la problemática sanitaria a la que se enfrenta el sector apícola, se justifica perfectamente la ejecución de un estudio de lucha frente a la varroosis, realizado en colmena Layens, colmena utilizada por el 80% de los apicultores españoles y mayoritaria en Salamanca. El estudio se ha ejecutado en esta provincia, que dispone del mayor número de apicultores profesionales y de colmenas y persigue que los resultados permitan a los apicultores mejorar la lucha contra esta parasitosis en sus explotaciones apícolas y mantener su viabilidad.Diputación de Salamanca.

The Use of Grape Seed Byproducts Rich in Flavonoids to Improve the Antioxidant Potential of Red Wines

The influence of adding seeds from grape pomace during Syrah wine fermentation in a warm climate has been studied. Seeds of Pedro Ximenez variety were rich in phenolic compounds, mainly flavonoids such as catechin and procyanidins. Changes in total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity of red wines were observed. These changes depended on the vinification stage and the amount of seeds (SW: 450 g or DW: 900 g seeds/150 kg grapes) applied. In general, antioxidant activity was greater when a simple dose (SW) was considered. Results indicate that seeds rich in flavonoids could be used as wine additives, which could improve the antioxidant potential of red wines in a warm climate.Ministerio de Economía y Competitividad AGL2014-58486-C2-2-

An SDP approach for multiperiod mixed 0-1 linear programming models with stochastic dominance constraints for risk management *

Abstract In this paper we consider multiperiod mixed 0-1 linear programming models under uncertainty. We propose a risk averse strategy using stochastic dominance constraints (SDC) induced by mixed-integer linear recourse as the risk measure. The SDC strategy extends the existing literature to the multistage case and includes both first-order and second-order constraints. We propose a stochastic dynamic programming (SDP) solution approach, where one has to overcome the negative impact the cross-scenario constraints, due to SDC, have on the decomposability of the model. In our computational experience we compare our SDP against a commercial optimization package, in terms of solution accuracy and elapsed time. We use supply chain planning instances, where procurement, production, inventory, and distribution decisions need to be made under demand uncertainty. We confirm the hardness of the testbed, where the benchmark cannot find a feasible solution for half of the test instances while we always find one, and show the appealing tradeoff of SDP, in terms of solution accuracy and elapsed time, when solving medium-to-large instances

Identifying the most suitable endogenous control for determining gene expression in hearts from organ donors

<p>Abstract</p> <p>Background</p> <p>Quantitative real-time reverse transcription PCR (qRT-PCR) is a useful tool for assessing gene expression in different tissues, but the choice of adequate controls is critical to normalise the results, thereby avoiding differences and maximizing sensitivity and accuracy. So far, many genes have been used as a single reference gene, without having previously verified their value as controls. This practice can lead to incorrect conclusions and recent evidence indicates a need to use the geometric mean of data from several control genes. Here, we identified an appropriate set of genes to be used as an endogenous reference for quantifying gene expression in human heart tissue.</p> <p>Results</p> <p>Our findings indicate that out of ten commonly used reference genes (<it>GADPH, PPIA, ACTB, YWHAZ, RRN18S, B2M, UBC, TBP, RPLP and HPRT</it>), <it>PPIA</it>, <it>RPLP </it>and <it>GADPH </it>show the most stable gene transcription levels in left ventricle specimens obtained from organ donors, as assessed using geNorm and Normfinder software. The expression of <it>TBP </it>was found to be highly regulated.</p> <p>Conclusion</p> <p>We propose the use of <it>PPIA</it>, <it>RPLP </it>and <it>GADPH </it>as reference genes for the accurate normalisation of qRT-PCR performed on heart tissue. <it>TBP </it>should not be used as a control in this type of tissue.</p
