Estéticas relacionales e interfaces: La idea de la posproducción en la experiencia del habitar

In the following paper we will develop an approach to put in reflection some questions that concern regarding the architectural dwell in the encounter with the concept of interface. It will advance through two views, focusing on the idea of experience and the sense of that experience in space.On the one hand, I would like us to stop at the interface, and analyze this idea as a component of the experience of an experiential aesthetic. On the other hand, that we open a critical discussion taking into consideration the contemporary implication of the concept of interface, which puts in view its relationship with the world of digitization or algorithmic abstraction. In other words: in the world´s construction from datification and circulation of information.Some further reflections will appear in a third moment, since the idea of interface allows us to open points of view for the creative processes in our time, a time that makes indisputable the rela-tion of the means in the conception of daily life. And so we can expand on a spectrum of relations on the idea of post production. Concept that Nicolás Bourriaud raised as the creative sign of the beginning of the century.A continuación, desplegaremos ciertas relaciones sobre la idea de interfaz que nos permiten poner en reflexión este concepto junto a la idea de habitar. Lo que expongo en ese sentido es que avancemos a través de dos miradas con enfoque de un pensamiento arquitectónico, o dicho de otro modo de un pensar sobre la idea de la experiencia y el sentido de esa experiencia en el espacio. Por un lado, me gustaría que nos detuviéramos en lo que refiere a la interfaz en cuanto es posible mirarla como un componente de análisis en la idea de una estética vivencial. Y por otro lado, que abriéramos una discusión crítica en torno a la interfaz, tomando en consideración la implicancia contemporánea que pone a la vista su relación con el mundo de la digitalización o abstracción algorítmica, incluso si quisiéramos plantearlo de otro modo, en la construcción de mundo desde la datificación y circulación de información. El motivo de esta distinción en dos flancos, es que comparezcan en un tercer momento algunas deliberaciones posteriores, en cuanto la idea de interfaz permite abrir puntos de vista para los procesos creativos en nuestra época, un tiempo que hace indiscutible la relación de los medios en la concepción del cotidiano. Y que así podamos ampliarnos en un espectro de relaciones en lo que esta presentación destaca como posproducción de la mano de lo que plantea Nicolás Bourriaud como el signo creativo del inicio de siglo

Among the different existing strategies used to tune the optoelectronic and magnetic properties of these nanostructures, the introduction of non-hexagonal rings inducing out-of-plane distortions is a promising pathway that has been scarcely explored on surfaces. Here, we demonstrate that non-hexagonal rings, in the form of tropone (cycloheptatrienone) moieties, are thermally transformed into phenyl or cyclopentadienone moieties upon an unprecedented surface-mediated retro–Buchner-type reaction involving a decarbonylation or an intramolecular rearrangement of the CO unit, respectively.Junta de Andalucía-Consejería de Economía y Conocimiento B-FQM-428-UGR20, BES-2015-072642, RYC2018-024364-IMCINMinisterio de Universidades FPU18/05938European Commission FOTOART-CM S2018/NMT-4367European Research CouncilSchweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung 200020-182015European Social FundUniversidad de GranadaEuropean Regional Development Fund 011033, PID2020-113142RB-C21, S2018/NMT-4367National Center of Competence in Research Materials’ Revolution: Computational Design and Discovery of Novel Materials 51NF40-182892Agencia Estatal de Investigació

Crecimiento y calidad espermática en trucha arcoíris Oncorhynchus mykiss (Teleostei: Salmonidae) durante la temporada reproductiva

Background. Oncorhynchus mykiss is a species that is widely cultivated in the world with high economic value. For this reason, it is essential to optimize its growth and reproduction for aquaculture. Goals. Evaluate the growth and sperm quality of rainbow trout during the reproductive season. Methods. We conducted research at the "El Zarco" Aquaculture Center in the state of Mexico, with 32 sexually mature three-year-old males. Once a month, we recorded total length, height, thickness (cm), and weight (g) during July-February, and calculated weight gain (WG), absolute growth rate (AGR), and instantaneous growth rate (IGR). Semen samples were obtained during (August-February). In order to evaluate the spermatic quality, we measured volume, color, consistency, concentration, pH, and mobility. Results. The highest AGR, WG, and IGR in terms of length and weight were obtained from July-August, i.e., a month prior to the reproductive period; from August-February the AGR was 1.13 cm, WG was 0.01 g, and there was an average IGR of 0.0321 ± 0.0522 cm and 0.0932 ± 0.2223 g. Differences (p <0.05) in length and weight were found between July and the months of the reproductive period. There was a pattern of semen production: It increased from August to October and then decreased until February, with significant differences (p <0.05). Usually, white semen and milky consistency were found. The highest sperm concentration occurred in September (8.17 ± 2.06 x 109 mL-1) and decreased until February, with significant differences (p <0.05) between months. The pH was alkaline with an average value of 8.07 ± 0.31. Mobility increased from August to December and decreased from January to February, with significant differences (p <0.05) between months. Conclusions. During the reproductive period, food energy is channeled to ensure reproduction, so that growth slows and sperm quality varies during the reproductive months.  Antecedentes. Oncorhynchus mykiss es una de las especies que más se cultiva en el mundo y que tiene alto valor económico, por tal motivo, optimizar su crecimiento y reproducción es fundamental para la acuacultura. Objetivos. Evaluar el crecimiento y calidad espermática en trucha arcoíris durante la temporada reproductiva. Métodos. La investigación se realizó en el centro acuícola El Zarco, Estado de México, con 32 machos sexualmente maduros de tres años. De julio a febrero se registraron mensualmente: longitud total, altura, grosor (cm), peso (g), ganancia de peso (GP), tasa de crecimiento absoluto (TCA) y tasa instantánea de crecimiento (TIC). Las muestras de semen se obtuvieron de agosto a febrero. Las variables para determinar la calidad espermática fueron: volumen, color, consistencia, concentración, pH y movilidad. Resultados. En cuando a longitud y peso, la mayor TCA, GP y TIC se obtuvo de julio a agosto, mes previo al periodo reproductivo. De agosto a febrero la TCA fue de 1.13 cm; GP de 0.01 g y TIC de 0.0321 ± 0.0522 cm y 0.0932 ± 0.2223 g en promedio. En julio se registraron diferencias en longitud y peso (p <0.05) en comparación con los meses del periodo reproductivo. El patrón de producción de semen se incrementó de agosto a octubre y decreció hasta febrero con diferencias significativas (p <0.05). En general, se encontró semen de color blanco y consistencia lechosa. La mayor concentración espermática se presentó en septiembre (8.17 ± 2.06 x 109 mL-1) y disminuyó hasta febrero, con diferencias significativas (p <0.05) entre los meses. El pH fue alcalino, con un promedio de 8.07 ± 0.31. La movilidad mostró un incremento de agosto a diciembre y un decremento de enero a febrero, con diferencias significativas (p <0.05) entre los meses. Conclusiones. Durante el periodo reproductivo la energía procedente del alimento se destina a asegurar la reproducción, por lo que el crecimiento se ralentiza y la calidad espermática varía entre los meses

Single-Molecule Conductance of 1,4-Azaborine Derivatives as Models of BN-doped PAHs

The single–molecule conductance of a series of BN-acene-like derivatives has been measured by using scanning tunneling break-junction techniques. A strategic design of the target molecules has allowed us to include azaborine units in positions that unambiguously ensure electron transport through both heteroatoms, which is relevant for the development of customized BN-doped nanographenes. We show that the conductance of the anthracene azaborine derivative is comparable to that of the pristine all-carbon anthracene compound. Notably, this heteroatom substitution has also allowed us to perform similar measurements on the corresponding pentacene-like compound, which is found to have a similar conductance, thus evidencing that B–N doping could also be used to stabilize and characterize larger acenes for molecular electronics applications. Our conclusions are supported by state-of-the-art transport calculations.This work has been supported by the MICINN projects PID2019-105458RB-I00, PID2019-106732GB-I00, PGC2018-101873-A-I00, CTQ2017-85454-C2-1-P, FIS2016-77889-R and MAT2017-88693-R, the European Research Council (ERC) (677023), the FEDER/Junta de Andalucía project A-FQM-221-UGR18 and the Comunidad de Madrid project NanoMagCOST (CM S2018/NMT-4321).

Degradation kinetics and thermodynamic analysis of betalains on microencapsulated beetroot juice using maltodextrin and sweet potato starch

Natural colorants have become important due to the health-benefits for humans. In that sense, it is important to evaluate the degradation kinetics of these components, in order to establish the stability under different processing and/or storage conditions. This study provides experimental and simulated results about the degradation of betalains in microencapsulated beetroot juice. Maltodextrin solution (MDX 10%) and sweet potato starch solution (SPS 2%) in proportions of 40MDX:60SPS, 20MDX:80SPS and 0MDX:100SPS were used as microencapsulating agents. The thermal degradation of betalains in the microencapsulated powders was evaluated at three temperatures (6, 19 and 30 °C) in order to predict the behavior under different conditions, using the first-order kinetic model. The kinetic parameters were identified using linear regression on the logarithmic curves of the experimental data to obtain the Arrhenius equations. The highest content of betalains was 2.58 mg/g and the lowest activation energy value was 48.71 KJ/mol, with both values corresponding to the powder that was microencapsulated with 20MDX:80SPS. The above results suggest high betalain stability in this powder, since there was less sensitivity to temperature in comparison to the rest of the powders. Additionally, some thermodynamic parameters were evaluated, which confirmed that the process is non-spontaneous and irreversible. The results obtained from this study, could be a useful tool to predict the minimal losses during processing, and gives the possibility to improve and select the food products where this kind of natural colorant can be applied.Natural colorants have become important due to their health benefits for humans.
