Mexico’s Tradition and Culture Entering the Digital Age: The Mexican Cultural Heritage Repository Project

Mexico is a country with a vast and extraordinary cultural heritage, which is the result of a rich history of cultural exchange, syncretism and transculturation. This rich culture has been materialized through the consolidation of a long and prestigious museum tradition, which at the same time is sadly characterized by an endemic lack of technological resources rather than professional skills. As a result, we have found that Mexican museums produce very heterogeneous forms of documentation, which are often not even managed using information technologies. Furthermore, most museums deploy ad hoc solutions that directly limit the usefulness and value of the documentation process itself. In response, the recently founded Mexican Ministry of Culture is undertaking the development of the Mexican cultural heritage data model (Modelo de Datos México), which is aimed at contributing to the cultural heritage domain of our country through the correct characterization and documentation of its cultural objects. It is the first documented experience in Mexico of a large-scale data model inspired by CIDOC-CRM, which is complemented by a set of terminological tools that attempt to capture the singularities and idiosyncrasies of the Mexican cultural sector. In the present paper, we will describe the motivations and decisions made so far to optimize the data model to the Mexican reality and the development of the project that will define a set of local terminologies built on the expertise of linguists, information architects, developers and especially, museum professionals.This research was funded by the Secretaría de Cultura of Mexico

Lay Concept of Aging Well According to Age: A ReAnalysis

Thus, as the document Futurage (2011), published as a Research Road Map in Europe, stated: “there is an urgent need to explore through multi-disciplinary and multi-country studies, involving qualitative and quantitative components, how older people themselves define healthy aging, including the oldest old.”Peer Reviewe

Mortality and refusal in the longitudinal 90+project

Attrition is one of the most important threats for longitudinal studies on aging mainly due to refusal and mortality. This study deals with those individuals who were assessed in the base line of 90+ project but died, dropped out or were examined in the follow-up. Participants of the 90+ project baseline consist of a sample of 188 older than 90 years, independent individuals (mean age = 92.9; 67 men and 121 women) living in the community (n = 76) or in residences (n = 112). They were assessed through the European Survey on Aging Protocol (ESAP) by collecting anthropometric, health and life styles, bio-behavioral, psychological and social data. After 6-14 months from the baseline, 55% individuals were re-assessed, 11% died and 34% dropped out for several reasons. Comparisons between the individuals deceased, interviewed and those who dropped out yielded significant differences mainly due to contextual variables. The mortality rate of participants living in residences is three times greater than those of participants living in the community. Trying to determine the differences between these three groups due to bio-psycho-social variables, we found that regular physical activity, mental status, leisure activities, fitness, perceived control and openness assessed at the baseline differentiate our three groups. Finally, 90% of those individuals who died were identified at the baseline as >non successful agers>, while more than a half of those who participated and a third of the non-participants were identified as >successful agers>. It can be concluded that among those independent but very old people, mortality is less important than willing to participate and contextual, behavioral and psychological factors are relevant for distinguishing mortality, survival and participation.Peer Reviewe

NiGa Unsupported Catalyst for CO2 Hydrogenation at Atmospheric Pressure. Tentative Reaction Pathways

The hydrogenation of CO2 is presented as a catalytic strategy for CO2 utilization and an approach to the development of sustainable processes to obtain products with high added value, such as CO, CH4, and CH3OH. An unsupported NixGay model catalyst with high surface area was synthesized by an ultrasonic-assisted coprecipitation method. The in situ H2-treatment and the activation temperature (600, 700, and 800 °C) are key in the phases present in the catalyst and, therefore, in the reactivity in the CO2 hydrogenation reaction at atmospheric pressure. Operating conditions have been selected that maximize the selectivity to be able to correlate phases, surface, and reactivity. Independently of the H2/CO2 feed ratio, after treatment in hydrogen at 600 °C, CO selectivity values are higher than 97%, via a reverse water gas shift reaction, with Ni13Ga9 and Ni metallic being the main phases detected. The H2-treatment at 700 °C increases the proportion of Ni0 and Ni13Ga9 phases, and even with the use of a H2/CO2 feeding ratio of 3, methanation is the only reaction that occurs. At 800 °C, Ni5Ga3 is the main phase detected, and methanol is formed at 150 °C, through the intervention of a necessary formate species; when the reaction temperature is higher than 400 °C, the rWGS is the only observable reaction, with complete CO formation.Funding for open access charge: Universidad de Málaga / CBU

“Education Network” a new way to teach Chemistry

The complexity of chemistry has implications for the teaching of chemistry. That chemistry is a very complex subject. The majority of the students at University think that chemistry is a difficult discipline and they have difficulty in understanding the concepts. Moreover, students' interest in chemistry decreases the first year at university. The reason for this decrease might be that the contents of chemistry laboratory classes are boring, out of date and lacking of dynamism that students experience through visual media tools. For these reasons, new programs and methodologies should be developed. Those are based on making chemistry relevant through problem solving and collaborative learning hold promise for reforming chemistry education. It is about an education according to circumstances, which is adapted to context and virtual behaviour of people. It's time to CRUSH boredom by transforming your classroom into an Escape Room adventure. School-based escape games are a great teaching tool. The students while playing, learn. The most important point is that they won’t realize they’re doing both at the same time. In this work, an educational gamification experience based on the escape room concept was developed. The first (Do It Yourself) DIY Escape Room was built the year before at Mechanical Engineer Degree started, that took more than three weeks of work. It was presented to other professors to the same subject at different degrees. That DIY Escape Room was modified and adapted to each group. Each professor changed the clues, problems and so on in order to orientate the topic as much as possible to their students.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Estudio DRIFTs-MS in situ de la oxidación de CO en condiciones subestequiométricas de oxígeno con un catalizador bimetálico Ni-Ce

El interés en la reducción de uno de los principales contaminantes atmosféricos como el monóxido de carbono hace que se hayan propuesto diversas técnicas para su eliminación. Actualmente, la oxidación catalítica a baja temperatura presenta gran interés, siendo los catalizadores soportados que contienen metales nobles, como Pt o Pd, los más estudiados. Los catalizadores bimetálicos Ni-Ce no soportados con alta área superficial han mostrado una importante población de vacantes de oxígeno, en comparación con sus equivalentes materiales soportados; mostrando un rendimiento considerable en la reacción de oxidación de CO, con prácticamente conversión completa por encima de los 460K. La actividad catalítica mejorada está relacionada con la presencia de la solución Ni-Ce-Ox que favorece las dos rutas involucradas en el mecanismo de oxidación de CO.Universidad de Málaga.

Invoking Chiral Vector Leptoquark to explain LFU violation in B Decays

LHCb has recently reported more than $2\sigma$ deviation from the Standard Model prediction in the observable $R_{J/\psi}$. We study this anomaly in the framework of a vector leptoquark along with other lepton flavor universality violating measurements which include $R_{K^{(*)}}$, and $R_{D^{(*)}}$. We show that a chiral vector leptoquark can explain all the aforementioned anomalies consistently while also respecting other experimental constraints

Perfil plurilingüe del alumnado de nuevo ingreso en el Campus de Melilla de la Universidad de Granada

XV Congreso Internacional de la Sociedad Española de Didáctica de la Lengua y la Literatura (SEDLL 2014), celebrado en Valencia, 19-21 de noviembre de 2014.Being competent in foreign languages is evident at university due to student mobility and the transmission of knowledge and research in a multilingual higher education. The Andalusian Council of Universities set the level B1 as a requirement for obtaining a university degree. In Melilla, this requirement is added to the high percentage of linguistic diversity that exists. This investigation describes the plurilingual reality of first-year students, and the socio-linguistic variables that account for results. With 206 subjects, we determine that a clear plurilingual profile exists, although their level in a foreign language is not sufficient to become independent users.Este trabajo forma parte del proyecto de investigación Estudio de la competencia multilingüe del alumnado universitario en el Campus Universitario de Melilla, incluido en el II Contrato-programa de investigación de la Facultad de Educación y Humanidades de Melilla. Plan 20 (2012-2014), financiado por el Vicerrectorado de Política Científica e Investigación de la Universidad de Granada (España)

Risk Assessment and Environmental Consequences of the Use of the Allium-derived Compound Propyl-propane Thiosulfonate (PTSO) in Agrifood Applications

The organosulfur compound propyl-propane thiosulfonate (PTSO), mainly found in Allium cepa, has a promising use in the agrifood industry. To confirm its safety for livestock, consumers, and environment, toxicological assessment is needed. In this regard, endocrine-disrupting chemicals (EDCs) are in the spotlight of research. Therefore, as part of the risk assessment of PTSO, in the present work, an in vivo study was performed in mice exposed to PTSO to investigate its potential reproductive toxicity considering fertility, genetic and endocrine endpoints. Five-weeks-old CD1 mice (80 males, 80 females) were exposed for 11 or 16 weeks (males or females, respectively) to different doses of PTSO (0, 14, 28 and 55 mg PTSO/kg b.w./day; 20 animals per group and sex) through the food pellets. No clinical observations or mortality and no changes in absolute organ weights and relative organ weights/body weight or brain ratios occurred during the study. The estrous cycle did not undergo any significant toxicologically relevant change. Most of the sex hormones displayed normal values. Some alterations in the expression of some genes related to reproduction is only observed in females, but they do not appear to have consequences in the development of sex organs. Docking results showed the impossibility of stable binding to estrogen and androgen receptors. Considering all the results obtained, the safe profile of PTSO can be confirmed for different agrifood applications at the conditions assayed.Junta de Andalucía P18-TP-2147Ministerio de Ciencia, Innovación y Universidades FPU2019-0124
