Susceptibility of Listeria monocytogenes planktonic cultures and biofilms to sodium hypochlorite and benzalkonium chloride
Félix Riesco Peláez: Department of Electrical Engineering and Systems Engineering and Automatic Control, University of León, E-24071, León, Spain[EN] The susceptibility of four L. monocytogenes isolates from pork to sodium hypochlorite (SHY) and benzalkonium chloride (BZK) was tested. Minimum inhibitory concentration (MIC) values of 3500 ppm (SHY), or between 3 ppm and 13 ppm (BZK), were found. Minimum bactericidal concentration (MBC) values ranged from 3500 ppm to 4500 ppm (SHY), and from 3 ppm to 14 ppm (BZK). The effect of SHY and BZK on the architecture and cellular viability of 24-h-old biofilms formed by such strains on polystyrene was determined through confocal laser scanning microscopy (CLSM) in conjunction with fluorescent dyes for live cells (SYTO 9) and dead cells (propidium iodide). Strains were able to form biofilm (biovolume values in the observation field of 14,161 μm2 ranged between 103,928.3 ± 6730.2 μm3 and 276,030.9 ± 42,291.9 μm3). Treatment of biofilms for 10 min with SHY (1MIC or 1.5MIC) or BZK (0.5MIC, 1MIC or 1.5MIC) decreased the biovolume of live (potentially dangerous) cells. SHY reduced the cellular viability of biofilms by more than 90%. On the other hand, BZK was able to remove most biofilm mass (live and dead cells), but decreased cellular viability only to a lesser extent, this suggesting strong biofilm detachment and dissemination of live cells.SIThis work was supported by the Spanish Ministerio de Economía, Industria y Competitividad (INIA; RTA2014-00045-C03-02)
The Impact of University–Industry Relationships on Firms’ Performance: A Meta-Regression Analysis
[EN] The University–Industry (U–I) relationship is a fundamental part of innovation systems. A wide spread of public resources has been given to promote this relationship and a large number of studies has evaluated the results. However, while innovation theory identifies this relationship as a positive instrument to increase firms’ performance, evaluation literature reports a wide range of findings. The lack of conclusiveness results in theory and evaluation literature motivates this meta-regression analysis (MRA), built on fifty-one micro-level studies published since 1995. After controlling for publication selection bias, sample, and study heterogeneities, our results show a small effect on firms’ performance. Specifically, the size of the effect is more significant for technical outcomes than economic ones. These findings have a lot of relevance for universities, firms, and policymakers for determining open-innovation strategies and public policieSIThis work was supported by the Spanish Ministry of Science, Innovation and Universities [FPU18/00343] and the Spanish Ministry of Science and Innovation through a research project [PID2019-105140RB-I00]
Proposal of 100% renewable energy production for the City of Cuenca- Ecuador by 2050
[EN] This research presents a scenario for a 100% renewable energy system for the City of Cuenca, Ecuador, with a projection to the year 2050. The transition process starts with Ecuador's change in the productive matrix with reforms from the legal and business strategies point of view to the year 2050. Advances in energy material are dependent on political uncertainty both at the country (Ecuador) and local (Cuenca) levels. It is possible to stop using fossil fuels due to the implementation of new renewable energy sources, potentially rich in the Ecuadorian Southwest and evidenced in the National Plan for a Lifetime. Currently, there is evidence of accelerated changes concerning legal regulations, including the construction of several electric power generation plants. This change in the national productive matrix implies, among others, the implementation of electric vehicles and the change of natural gas stoves for electric ones, and the implementation of the “4 Rios” tram that crosses the city from North-South and South-North, incorporating 100% renewable energy generation, which would provide heat in urban and marginal urban areas. All the systems created in Ecuador, such as heating, cooling, transportation, security etc., will allow an increasing penetration of renewable energy until it reaches 100%.S
The revitalization of the classics on the stage: "El castigo sin venganza" from Lope de Vega in version by Eduardo Vasco
[ES] Se tratará de analizar la puesta en escena de El castigo sin venganza de Lope de Vega,
llevado a las tablas por la CNTC bajo la dirección de Eduardo Vasco en 2005 y la innovación
que supuso. De ese modo, el género dramático sumará la tradicional investigación filológica
del texto con la representación teatral, fin último de este género.[EN] It will try to analyze the staging of El castigo sin venganza by Lope de Vega in the Eduardo
Vasco’s version of 2005, when Vasco directed the National Classical Theater Company (CNTC) and
the innovation that it entailed. In this way, the dramatic genre will add the traditional philological
investigation of the text with the theatrical performance, last purpose of this genre
Feature analysis for data-driven APT-related malware discrimination
[EN] Advanced Persistent Threats (APTs) have become a major concern for IT security professionals around the world. These attacks are characterized by the use of both highly sophisticated, evasive and cautious human and technical resources. It is very common to notice the combined use of different malware in long APT campaigns. This fact makes it interesting to investigate the malware that has been used in APT campaigns. Different approaches have been proposed to find discriminatory features to detect APT malware. Features from either static, dynamic and network-related analyses have been separately proposed for that aim. The new approach considered in this study aims to identify the most discriminatory features to distinguish APT-campaign-belonging malware from non-APT malware executables. This approach suggests to identify the discriminatory features from not one but all three groups of these analyses by using domain knowledge and with a purpose of interpretability. As a result, a set with the most discriminatory features of each type is provided. To achieve this set, well-known machine learning techniques have been used. One of the most important limitations in the use of these learning techniques is the availability of a relevant amount of data. In this paper, a large dataset of 19,457 malware samples is publicly provided, including both malware known to be related with APTs and generic non-APT-belonging malware samples. In order to analyze the discrimination ability of the features, the proposed approach follows several steps. First, an exploratory analysis is conducted to obtain knowledge about the data structure. Later, feature selection is performed using different discriminatory techniques. The resulting selection of features is assessed by means of four well-known binary classification techniques. The high accuracy of the results shows that the proposed features are discriminative enough for the stated purpose. Finally, these results are interpreted and the findings are discussed from the perspective of prior knowledge and assumptions about APT-related malware.SIWe wish to thank to Scayle (Supercomputación de Castilla y León) for their funding and suppor
"The blue centaur": presence and suversion of classical mythology
[ES] La mitología clásica ha trascendido no solo géneros y estilos, sino también épocas,
contando con un enorme atractivo hasta la actualidad, pues ha sabido adaptarse a las
necesidades de la realidad imperante adoptando funciones y formas muy heterogéneas.
Este trabajo pretende constatar la presencia de la mitología clásica en el cuento «El Centauro
azul», donde, además de analizarse la figura del centauro, se resaltan otros aspectos,
como el humor o la simbología del color azul, para hablar de una nueva funcionalidad.
Esta interpretación reafirmaría la subversión mitológica como una práctica habitual en la
búsqueda de nuevas finalidades. Por último, y a modo de marco contextual que justifique
estas observaciones, se pretende reflejar la importancia de la mitología en la literatura
del Siglo de Oro español, donde su recepción supuso la mezcla entre el clasicismo y el
exotismo, abriendo a los lectores de la época un mundo novedoso para ellos.[EN] Classical mythology has transcended not only genres and styles, but also eras, having
enormous appeal up to the present, as it has known how to adapt to the needs of the prevailing
reality, adopting very heterogeneous functions and forms. This work aims to verify the presence
of classical mythology in the story «El Centauro azul», where, in addition to analyzing the figure
of the centaur, other aspects are highlighted, such as humor or the symbology of the color blue, to
talk about a new functionality. This interpretation would reaffirm mythological subversion as a
common practice in the search for new goals. Lastly, and as a contextual framework that justifies
these observations, it is intended to reflect the importance of mythology in the literature of the
Spanish Golden Age, where its reception meant the mixture between classicism and exoticism,
opening up to the readers of the time a new world for them
Repeatability and Reliability of the Rheumatoid Arthritis Foot Disease Activity Index in Spanish Patients: A Transcultural Adaptation
[EN] Background: The Rheumatoid Arthritis Foot Disease Activity Index (RADAI-F5) question-naire, based on five questions, is used to assess the severity of rheumatoid arthritis disease in the foot. Nowadays, RADAI-F5 has been validated in different languages; however a Spanish version was lacking. Therefore, the purpose of this research was to translate and validate the Spanish version (RADAI-F5-es). Methods: A cross-cultural translation of the RADAI-F5 questionnaire was performed from English to Spanish. To validate its use, 50 subjects with rheumatoid arthritis who responded to the translated questionnaire two times in an interval of less than 3 months were selected in order to verify the psychometric properties. Results: Excellent agreement between the two versions according to the Cronbach’s α was shown. Five domains with regards to arthritis activity in foot joint tenderness and swelling, foot arthritis pain, general foot health and joint stiffness were added together to obtain the total score. Excellent retest reliability was shown for the total score. Test/retest reliability was excellent for joint stiffness on awakening and foot arthritis pain domains. There were no significant differences among any domains (p > 0.05). There were no statistically significant differences (p = 0.000) for the mean ± standard deviations (SD) between pre-and post-tests (98.09 ± 15.42) [93.75–102.43] and 97.96 ± 13.88 [94.5–101.86] points, respectively). Bland–Altman plots or clinically pertinent variations were not statistically significantly different. Conclusions: The RADAI-F5-es is considered a valid and strong tool with adequate repeatability in the Spanish communityS
