Propuesta para mejorar la tecnología en la producción de la cerámica que permita potenciar el turismo del distrito de Chulucanas-Piura año 2011

El presente trabajo de investigación pretende brindar una nueva alternativa para optimizar las tecnologías que se vienen empleando en la producción de la cerámica y que de esta manera se logre potenciar el Turismo en el distrito de Chulucanas-Piura. La cerámica desde la década de los años 70 se ha convertido en nuestro producto bandera, es aquí donde los artesanos chulucanenses y de otras localidades cercanas demuestran el arte y creatividad que llevan en sus manos. Pretendemos establecer una propuesta participativa entre los ceramistas y los organismos públicos del sector turístico para que trabajando conjuntamente realicen, por ejemplo, alianzas estratégicas con otras entidades públicas, así como también busquen mercados internacionales donde ofrecer nuestra cerámica, a su vez implementar talleres de capacitación a los artesanos que promueva la búsqueda de nuevas tecnologías que se apliquen a la producción de la cerámica. Todo esto ocurre debido a que hemos podido identificar que actualmente la tecnología que se aplica para producir los ceramios no es la más adecuada, ello implica que el desarrollo haya sufrido un detenimiento y una posterior crisis en los ceramistas quienes reclaman el apoyo por parte de las instituciones públicas y del sector turístico, para que nuestra cerámica mejore su calidad y recupere su prestigio tanto en el ámbito nacional como internacional. Con esto queremos alcanzar un desarrollo turístico en nuestra localidad, que implique pues, la puesta en valor de los recursos turísticos, el mejoramiento de la infraestructura básica de servicios turísticos que se refleje en el aumento del flujo de turistas a nuestra región

The global abundance of tree palms

Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. We quantified global patterns of tree palm relative abundance to help improve understanding of tropical forests and reduce uncertainty about these ecosystems under climate change. Location Tropical and subtropical moist forests. Time period Current. Major taxa studied Palms (Arecaceae). Methods We assembled a pantropical dataset of 2,548 forest plots (covering 1,191 ha) and quantified tree palm (i.e., ≥10 cm diameter at breast height) abundance relative to co‐occurring non‐palm trees. We compared the relative abundance of tree palms across biogeographical realms and tested for associations with palaeoclimate stability, current climate, edaphic conditions and metrics of forest structure. Results On average, the relative abundance of tree palms was more than five times larger between Neotropical locations and other biogeographical realms. Tree palms were absent in most locations outside the Neotropics but present in >80% of Neotropical locations. The relative abundance of tree palms was more strongly associated with local conditions (e.g., higher mean annual precipitation, lower soil fertility, shallower water table and lower plot mean wood density) than metrics of long‐term climate stability. Life‐form diversity also influenced the patterns; palm assemblages outside the Neotropics comprise many non‐tree (e.g., climbing) palms. Finally, we show that tree palms can influence estimates of above‐ground biomass, but the magnitude and direction of the effect require additional work. Conclusions Tree palms are not only quintessentially tropical, but they are also overwhelmingly Neotropical. Future work to understand the contributions of tree palms to biomass estimates and carbon cycling will be particularly crucial in Neotropical forests

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Performance of Different Experimental Absorber Designs in Absorption Heat Pump Cycle Technologies: A Review

The absorber is a major component of absorption cycle systems, and its performance directly impacts the overall size and energy supplies of these devices. Absorption cooling and heating cycles have different absorber design requirements: in absorption cooling systems, the absorber works close to ambient temperature, therefore, the mass transfer is the most important phenomenon in order to reduce the generator size; on the other hand, in heat transformer absorption systems, is important to recover the heat delivered by exothermic reactions produced in the absorber. In this paper a review of the main experimental results of different absorber designs reported in absorption heat pump cycles is presented

ENGIU: Encuentro Nacional de Grupos de Investigación de UNIMINUTO.

El desarrollo del prototipo para el sistema de detección de Mina Antipersona (MAP), inicia desde el semillero ADSSOF perteneciente al programa de Administración en Seguridad y Salud en el trabajo de la UNIMINUTO, se realiza a partir de un detector de metales que emite una señal audible, que el usuario puede interpretar como aviso de presencia de un objeto metálico, en este caso una MAP. La señal audible se interpreta como un dato, como ese dato no es perceptible a 5 metros de distancia, se implementa el transmisor de Frecuencia Modulada FM por la facilidad de modulación y la escogencia de frecuencia de transmisión de acuerdo con las normas y resolución del Ministerio de Comunicaciones; de manera que esta sea la plataforma base para enviar los datos obtenidos a una frecuencia establecida. La idea es que el ser humano no explore zonas peligrosas y buscar la forma de crear un sistema que permita eliminar ese riesgo, por otro lado, buscar la facilidad de uso de elementos ya disponibles en el mercado
