Diseño y desarrollo de un sistema de refrigeración distribuido basado en comunicaciones CANBUS

Este proyecto se ha realizado sobre el LaunchPad Tiva™ C Series TM4C123G de Texas Instruments y el transceptor CANbus MCP2562 de Microchip. Presenta un doble objetivo: primero, el desarrollo de un sistema de control de refrigeración distribuido mediante el uso de ventiladores y sensores de temperatura conectados a launchpads; segundo, la expansión de las posibilidades en relación con el launchpad y las prácticas impartidas en el M.I.E.R.A, dejando la posibilidad de expandir tanto el proyecto como las prácticas. El trabajo cuenta con dos partes bien diferenciadas: La primera parte consiste en la realización, mediante el programa informático “KiCad” (software libre similar al “Eagle”), de una placa similar al boosterpack utilizado en las prácticas del Master en Ingeniería Electrónica, Robótica y Automática (M.I.E.R.A) que permita incluir la conexión de los ventiladores y los sensores de temperatura. La segunda parte consiste en la programación por medio del programa informático “Code Composer Studio” (CCS) de tres terminales: dos que actúan como nodos, que se van a encargar de leer la temperatura por medio de sensores y de accionar los ventiladores; y uno que actúa como master, recibiendo la temperatura y convirtiéndola a un valor de pwm para cada ventilador.This project has been done with the Texas Intruments Tiva™ C Series TM4C123G LaunchPad and the Microchip™ CANbus MCP2562 transceptor.

Dynamic capacities and the influence on the innovative potential of urban hotels

The irruption in the theory of intangible assets, as one of the essential resources of the contemporary organization, places innovation management at the center of organizational strategies. Several approaches are used to study innovation from a business perspective; however, the Theory of Resources and Capacities gains strength to understand the organization. It specializes in knowledge management, the dynamics approach, and the capacity for innovation. That is why this article analyzes the state of development of dynamic capabilities in hotels in the city of the destination Havana and its effect on their innovative performance. For this, the emotional capacities are defined, and the indicators to be measured are established, taking into account the particularities of the accommodation activity. As a result, it is possible to determine the state of the dynamic capacities, and the influence of these on the innovative performance of the hotels studied is analyzed. As well as the viability of the Theory of Resources and Capacities to promote innovation in hotels

RAMADAN PRECEPTS AND COMPLIANCE WITH LABOR RISK PREVENTION. HEALTH CONSEQUENCES AND RECOMMENDATIONS

The precepts followed by Muslim people during the Ramadan season, mainly fasting and abstinence from liquids, as well as changing time habits, can increase occupational risk situations. There is a social perception that can lead to mystify the seriousness of these situations and, therefore, lead to situations of discrimination. This work aims to contribute modestly to the demystification of this incidence in risk prevention, examining the scientific literature and studies on occupational accidents. Additionally, a series of recommendations are made to enable the compatibility of religious practice and safe working during the month of Ramadan regarding occupational health and safety of workers

Confort higrotérmico para actividades en espacios exteriores: periodo cálido, en clima cálido seco extremo

El tiempo de duración de las actividades en espacios exteriores en clima cálido seco extremo, depende de las condiciones de confort higrotérmico de los usuarios. Además por condiciones de ambiente térmico existen riesgos como deshidratación o golpe de calor. El objetivo del presente estudio fue estimar condiciones confort por temperatura y humedad relativa de usuarios de espacios exteriores de un centro recreativo de Mexicali, Baja California, México. Se presenta la estimación de temperatura y humedad relativa neutral con rangos de confort térmico para espacios exteriores, en el período cálido en un clima desértico. Se diseñó un cuestionario basado en ISO 10551, se midieron temperatura de bulbo seco y humedad relativa. Se aplicaron 822 encuestas en julio y agosto del 2008. Se estimaron temperatura y humedad relativa neutra y rangos de confort con el método de medias por intervalo de sensación térmica. El análisis se hizo para tres niveles de actividad: pasiva, moderada e intensa y uno combinado con los tres niveles. El período analizado presentó un comportamiento de clima asimétrico. Los valores de temperatura son aproximadamente simétricos con respecto a sus rangos de confort térmico, mientras que el confort por humedad relativa en actividad moderada e intensa fue asimétrico. Las temperaturas y humedad relativa neutras obtenidas muestran que los sujetos en actividad intensa, con práctica periódica de ejercicio y hábitos apropiados a las condiciones de clima, tienen una temperatura y humedad relativa de confort similar a aquellos con actividad pasiva.The duration of outdoor activities in extreme dry in warm weather, depends on the hygrothermal comfort conditions for users. In addition to the thermal environment conditions there are risks such as dehydration or Heat Stroke. The objective of this study was to estimate the comfort conditions for temperature and relative humidity of outdoor users of a recreational center in Mexicali, Baja California, Mexico. This work shows the estimated neutral temperatura, neutral relative humidity and thermal comfort ranges during the warm period for a public recreational green area located on a desert climate. A questionnaire was designed based on the scale of thermal sensation of ISO 10551 were measured dry bulb temperatura and relative humidity. A total of 822 questionnaires were applied during the months of July and August 2008. By estimated neutral temperatura, neutral relative humidity and comfort range with a statistical method of correlation. The analysis was done for three activity levels: passive, moderate e intense, besides the three levels together. The period of climate analyzed was asymmetric. The neutral temperature values obtained are approximately symmetrical with respect to the thermal comfort range, while the relative humidity comfort for moderate and intensity activity was asymmetric. The neutral temperatures and relative humidity obtained show that the intense activity in subjects with regular exercise and practice habits appropriate to the weather conditions, had a temperature of comfort similar to subjects with passive activity.Peer Reviewe

Nutritional Impact and Eating Pattern Changes in Schizophrenic Spectrum Disorders after Health Education Program on Symbiotic Dietary Modulation Offered by Specialised Psychiatric Nursing–Two-Arm Randomised Clinical Trial

Background: The traditional therapeutic approach has perceived the role of nutrition as a minor intervention in psychiatry. The microbiota–gut–brain axis theory evidences the influence of dietary and nutritional patterns on mental health. Aims: To evidence the impact of dietary advice on increasing symbiotic intake on nutritional status and dietary habits in individuals with schizophrenia spectrum disorders. Methods: Randomised clinical trial (two-arm, double-blind, balanced-block, six-month intervention) in 50 individuals diagnosed with schizophrenia spectrum disorders. The control group received conventional dietary advice on an individual basis. A personal nutritional education programme was established in the intervention group (IG) to increase prebiotic and probiotic intake through dietary advice (dairy and fermented foods, green leafy vegetables, high-fibre fruit, whole grains, etc.). Data on nutritional status and dietary habits were collected (baseline and six months). The degree of dietary adherence to the recommended patterns was recorded weekly. Anthropometric parameters were also analysed monthly. Results: Finally, 44 subjects completed the follow-up. All participants exceeded the dietary reference intakes. The overall and intra-group analysis showed a statistically significant (p < 0.05) reduction in macro and micronutrient intakes with a closer approximation to the recommended dietary intakes, except for polyunsaturated fatty acids, oligosaccharides, polysaccharides and dietary fibre. After six months of intervention, statistical differences (p < 0.001) were found in all variables of the anthropometric profile in the IG, as well as an increase in the consumption of foods with a high symbiotic content (at baseline and six months). Likewise, a reduction in eggs, meat, fish, sugars and ultra-processed foods was evident, leading to significant intra-group differences (p < 0.05). Conclusions: Implementing conventional nutritional education strategies and specific nutritional advice with a symbiotic effect improves the dietary-nutritional profile in patients with schizophrenia spectrum disorders. Furthermore, it highlights the nutritional impact on mental health, stating itself as adjuvant therapy for physical health and lifestyle improvement

Use of a flor yeast strain for the second fermentation of sparkling wines: Effect of endogenous CO2 over-pressure on the volatilome

Saccharomyces cerevisiae flor yeast is used for the first time in sparkling wine-making. Twenty-six oenological variables and fifty-three volatile metabolites are quantified in the middle (P = 3 bar) and at the end (P = 6 bar) of the second fermentation, carried out in open and closed bottles. A heat-map of volatiles and the fingerprints obtained for ten chemical families and ten odorant series visualize the changes for each condition. Terpenes, fatty acids and volatile phenols increased their contents by pressure effect at the end of the study by 25.0, 7.8 and 2.2%, respectively. The remaining families decrease between 17.4% and 30.1% for furanic compounds and esters in the same stage. A Principal Component Analysis established that nine volatiles are mainly affected by pressure and five by fermentation stage. The use of ethanol-tolerant flor yeasts constitutes an innovative procedure for the enhancement of the sparkling wines diversification.info:eu-repo/semantics/acceptedVersio
