Abstract: The present study aims to know the flow patterns in two nanorefrigerants R600a / CuO and R410A / CuO throughout the forced boiling process in horizontal square pipes. Those are obtained using the thermophysical properties of the refrigerants R600a and R410A in state liquid and vapor, as well as the properties of the CuO nanoparticles. The analysis was carried out using two methods: analytical and numerical. The analytical method was established by formulas and correlations through scientific articles and books to find an improvement in the two-phase heat transfer, under the conditions at an inlet temperature of 8 ° C and with a quality range of 0 to 1. This allowed to verify that by adding nanoparticles to the refrigerant, the transition between the flow regimes increases progressively, while the quality of the vapor decreases. For the numerical method, the different transition limits are specified in a simulation process in the Ansys Fluent CFD Software, under established design conditions, which consequently increases the general efficiency of any refrigeration system.

Resumen: El presente estudio tiene como propósito identificar los patrones de flujo en los nanorefrigerantes R600a/CuO y R410a/CuO durante el proceso de ebullición forzada en tuberías cuadradas horizontales. Dichos patrones se obtienen empleando las propiedades termofísicas de los refrigerantes R600a y R410A en estado líquido y de vapor, así como, también las propiedades de las nanopartículas de CuO. El análisis se lo realizó mediante dos métodos: analítico y numérico. El método analítico se estableció mediante fórmulas y correlaciones a través de artículos científicos y libros para encontrar una mejora en la transferencia de calor de dos fases. El trabajo se llevo a cabo bajo las condiciones a una temperatura de entrada de 8 °C y con un rango de calidad de 0 a 1, comprobando que al añadir nanopartículas al refrigerante la transición entre los regímenes de flujo aumenta de manera progresiva, mientras que, la calidad de vapor reduce. Para el método numérico se procedió a especificar los diferentes límites de transición en un proceso de simulación en el Software CFD Ansys Fluent, bajo condiciones establecidas de diseño, lo que en consecuencia aumenta la eficiencia general de cualquier sistema de refrigeración.

Abstract: This paper presents and discusses the results of a project aimed at investigating the mechanical behaviour of typical shear walls of light frame constructions and built with frame of Argentinean Eucalyptus grandis (eucalipto). The research was carried out on 17 panels, 15 of which distributed in 5 series with different configurations that met the construction requirements specified in Method A of Eurocode 5 UNE-EN 1995-1-1 and 2 presenting anomalies. All tests were carried out according to UNE-EN 594. The racking resistance determined experimentally exceeded that calculated according to the aforementioned Method in all panels that fulfil the construction requirements, placing the value calculated according to the European rules on the safety side. The experimental results confirmed a greater variability for the stiffness than for the resistance, and showed that the panels that failed under high loads do not always developed the expected resistance for allowable deformations under service loads, indicating the convenience of focusing on this aspect in future investigations on this structural system.

Resumen: En este artículo se presentan y discuten los resultados de un proyecto orientado a investigar el comportamiento mecánico de muros de corte típicos de construcciones de entramado ligero y construidos con bastidor de Eucalyptus grandis (eucalipto) de la Mesopotamia Argentina. La investigación se llevó a cabo sobre 17 paneles, 15 de los cuales integraron 5 series con distintas configuraciones que cumplieron los requerimientos constructivos del Método A del Eurocódigo 5 UNE-EN 1995-1-1, y 2 con anomalías. Los ensayos se realizaron según la norma UNE-EN 594. La resistencia al descuadre determinada experimentalmente superó a la obtenida según el Método A en todos los paneles que cumplieron los requerimientos constructivos, ubicando del lado de la seguridad al valor calculado según las reglas europeas. Los resultados experimentales probaron una mayor variabilidad de la rigidez que de la resistencia y mostraron que los paneles que fallaron bajo cargas elevadas no siempre desarrollaron la resistencia esperada para deformaciones admisibles bajo cargas de servicio, indicando la conveniencia de focalizar sobre este aspecto en futuras investigaciones sobre estos sistemas estructurales.

ABSTRACT This study aimed to determine the antibiotic profile of microorganisms isolated from urine samples of patients with community urine tract infections (UTI) admitted to the University Hospital of the Federal University of Sao Carlos to support an appropriate local empirical treatment. A retrospective cross-sectional study was conducted from October 2018 to October 2020. Data from 1,528 positive urine cultures for bacterial pathogens and antibiograms were tabulated. Bacterial species prevalence and their resistance profile were analyzed and compared by sex and age. For Gram-negative fermenting bacteria, resistance rates were compared between patients with previous hospitalization and the total of infections caused by this group. For comparisons, the Chi-square test was performed, using Fisher’s exact test when necessary (BioEstat program, adopting p ≤ 0.05). A multivariate analysis was applied to assess the effect of the studied variables in predicting multidrug resistance. Infections were more prevalent in women and older adults. Gram-negative bacteria represented 90.44% of total cultures. In both sexes, E. coli prevalence was significantly higher in adults compared with older adults (p < 0.0001). For several antibiotics, resistance rates were higher in the older adults compared with other ages and in patients with Gram-negative fermenting infections and previous hospitalization compared with the total of infections by this group of bacteria. The closer to the hospitalization, the higher the number of antibiotics with superior resistance rates. Resistance rates for aminoglycosides, carbapenems, ceftazidime, nitrofurantoin, piperacillin+tazobactam, and fosfomycin were less than 20%, considered adequate for empirical treatment. Only hospitalization in the previous 90 days was statistically significant in predicting infections by multidrug-resistant bacteria.

ABSTRACT: The road system is the main mode used for the transportation of agricultural cargo, and in some cases, it is the only option for handling this type of product. This dependence means that the implementation of tools to support the management of logistical costs can reduce the financial impact with the transport felt by the economic agents operating in the soybean chain. This study contributed to a better understanding of the variables that make up the cost of road freight, generating a system of road freight prediction from a multiple linear regression model using the selection of variables Stepwise, Forward, and Backward elimination. This being said, this research intends to evaluate whether the behavior of soybean road freight is influenced by the variables that make up the productive, economic, and infrastructure dimensions in price formation. The regression models had an explanatory power of 87.20%. In the infrastructure dimension, the most impact variable in soybean road freight was the distance traveled; in the economic dimension, the variables of inflation and fuel price stood out; while in the productive dimension, the main contribution was the volume of production. A more assertive predictability of logistical costs and better understanding of the dynamics of freight price formation helps industry agents in planning and decision-making. Another contribution of this study is that it can be used as a practical tool for predicting soybean road freight on several transportation routes.

RESUMO: O sistema rodoviário é o principal modal utilizado para o transporte de cargas agrícolas, e em alguns casos, é a única opção para movimentação desse tipo de produto. Esta dependência faz com que a implementação de ferramentas para apoiar a gestão dos custos logísticos possa reduzir o impacto financeiro com o transporte sentido pelos agentes econômicos que atuam na cadeia da soja. O presente trabalho visa contribuir para um melhor entendimento das variáveis que compõem o custo dos fretes rodoviários, gerando um sistema de previsão de fretes rodoviários a partir de um modelo de regressão linear múltipla usando a seleção de variáveis Stepwise, Forward e a eliminação Backward. Isto posto, a pesquisa tem por objetivo avaliar se o comportamento do frete rodoviário da soja é influenciado pelas variáveis que compõem as dimensões produtivas, econômicas e de infraestrutura na formação do preço. Os modelos de regressão tiveram um poder explicativo de 87,20%. Na dimensão infraestrutura o destaque foi a variável distância percorrida como a mais impactante no frete rodoviário da soja, na dimensão econômica as variáveis inflação e preço do combustível, enquanto que na dimensão produtiva a principal contribuição foi o volume de produção. A previsibilidade mais assertiva dos custos logísticos e melhor compreensão da dinâmica de formação do preço do frete auxilia os agentes do setor no planejamento e na tomada de decisão. Outra contribuição deste trabalho é que pode ser usado como uma ferramenta prática para a predição de fretes rodoviários da soja em diversas rotas de transporte.

Abstract: The objective of this study was to characterize the morphological composition of five populations of native maize and estimate their yields using agricultural practices without the use of agrochemicals. The study conducted in 2021, in the municipality of Cintalapa, Chiapas, within the experimental field of the Regional Academic Center of the Antonio Narro Autonomous Agrarian University. The five populations of native maize were provided by farmers from different regions of the state, with prior informed consent. The Agricultural practices consisted of using plant extracts and potassium soap with neem extract (Azadirachta indica) to prevent and combat pests. For fertilization, Californian red earthworm (Eisenia foetida) leachate and bat guano were applied in their commercial presentation. Morphological characters were evaluated with a descriptive statistical analysis considering days to male and female flowering, plant and ear height ear length and diameter, number of rows per ear and number of kernels per row. Grain yield was estimated by the weight of the ear harvested from a random sample of 20 plants per population. Numerical differences of the studied variables were identified, which demonstrates an existing genetic diversity. The populations with the highest yields were Campeón and Olotillo, with 5.37 and 4.4 ton ha-1 (± 1.24), respectively. The data provide information to design native maize conservation strategies through agrochemical-free management.

Resumen: El objetivo de este estudio fue caracterizar morfológicamente cinco poblaciones de maíz nativo y estimar sus rendimientos, empleando prácticas agrícolas sin uso de agroquímicos. El estudio se realizó en el año 2021, en el municipio de Cintalapa, Chiapas, dentro del campo experimental del Centro Académico Regional de la Universidad Autónoma Agraria Antonio Narro. Las cinco poblaciones de maíz nativo fueron proporcionadas por campesinos de diferentes regiones de la entidad, con previo consentimiento informado. Las prácticas agrícolas consistieron en uso de extractos vegetales y jabón potásico con extracto de neem (Azadirachta indica) para la prevención y combate de plagas. Para la fertilización se aplicó lixiviado de lombriz roja californiana (Eisenia foetida) y guano de murciélago en su presentación comercial. Los caracteres morfológicos se evaluaron con un análisis estadístico descriptivo considerando: días de floración masculina y femenina, alturas de planta y mazorca, longitud y diámetro de la mazorca, y número de hileras por mazorca y número de granos por hilera. El rendimiento de grano se estimó mediante el peso de la mazorca cosechada de una muestra aleatoria de 20 plantas por población. Se identificaron diferencias numéricas de las variables estudiadas, lo que demuestra una diversidad genética existente. Las poblaciones que presentaron mayores rendimientos fueron Campeón y Olotillo, con 5,37 y 4,4 ton ha-1 (± 1,24), respectivamente. Los datos aportan información para diseñar estrategias de conservación de maíces nativos con manejo libre de agroquímicos.

Resumo O objetivo deste artigo é identificar a prevalência e avaliar os fatores associados aos comportamentos extremos para perda de peso em adolescentes do Nordeste brasileiro. Estudo transversal com 2.439 adolescentes da Amostra 2 (2015) da Pesquisa Nacional de Saúde do Escolar. Os comportamentos extremos para perda de peso (desfecho) e as variáveis independentes foram avaliadas por meio de um questionário eletrônico autoaplicável. A análise estatística foi realizada seguindo um modelo conceitual hierárquico. A prevalência de comportamentos extremos para perda de peso na amostra foi de 12,1%. Entre os fatores que mostraram associação significativa com o desfecho, destacam-se a situação administrativa da escola privada (RP = 0,62; IC = 0,46-0,84), ser vítima bullying relacionado à aparência corporal e pelos demais motivos (RP = 1,62; IC = 1,19-2,20), ser forçado a ter relação sexual (RP = 2,65; IC = 1,90-3,69), ter insônia (RP = 1,84; IC = 1,43-2,37) e se autoperceber como gordo ou muito gordo (RP = 1,90; IC = 1,50-2,42). Prevalência moderada de comportamentos extremos para perda de peso foi identificada entre os adolescentes. Os fatores socioeconômicos, de exposição à violência, de saúde mental e da imagem corporal se associaram à adoção de tais comportamentos.

Abstract The objective of this article is to identify the prevalence and evaluate the factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil. Cross-sectional study with 2,439 adolescents from Sample 2 (2015) of the National School-based Health Survey. Extreme weight loss behaviors, such as self-induced vomiting, laxative use and use of medicines or formulas (outcome) and independent variables were evaluated using a self-administered electronic questionnaire. The statistical analysis was performed following a hierarchical conceptual model. The prevalence of extreme weight loss behaviors in the sample was 12.1%. Among the factors that showed significant association with the outcome, we emphasize the administration model of the private school (PR = 0.62; CI = 0.46-0.84), bullying related to body appearance and for other reasons (PR = 1.62; CI = 1.19-2.20), forced sexual intercourse (PR = 2.65; CI = 1.90-3.69), insomnia (PR = 1.84; CI = 1.43-2.37), and be perceived as fat or very fat (PR = 1.90; CI = 1.50-2.42). Moderate prevalence of extreme weight loss behaviors was identified among adolescents. Socioeconomic factors, exposure to violence, mental health, and body image were associated with the adoption of these behaviors.

ABSTRACT The earthquake of March 4th, 1904, as a natural phenomenon, evidenced the vulnerability in the construction materials of the buildings in Lima. This type of study brings us closer to those of historical seismology as long as its relationship as a natural phenomenon with society is analyzed in a diachronic way. Thus, it is also important to point out that studies of natural disasters have as their main purpose the implementation of measures that contribute to reduce the vulnerability of the populations that are frequently affected by them, so as to prevent the effects. For this study, newspaper articles describing the phenomenon and its effects were used as the main sources. Despite the fact that this phenomenon did not generate a disaster with a high number of victims and losses, the authorities and the population did not take the necessary measures to modify the construction patterns, construction materials and territorial ordering with preventive intentions in the future, maintaining and even increasing the vulnerability in the city.

RESUMEN El temblor del 4 de marzo de 1904, como fenómeno natural, evidenció la vulnerabilidad en los materiales de construcción de las edificaciones de la ciudad de Lima. Este estudio nos acerca a los trabajos de sismología histórica, en tanto se analiza su relación como fenómeno natural con la sociedad de manera diacrónica. Es importante señalar que los estudios de los desastres naturales tienen como principal objetivo la puesta en práctica de medidas que contribuyan a reducir la vulnerabilidad de las poblaciones que se ven frecuentemente afectadas por estos, de manera que prevengan los efectos. Para este estudio se utilizaron como fuentes principales los artículos periodísticos que describen el fenómeno y sus consecuencias. A pesar de que el sismo no generó un desastre con alto número de víctimas y pérdidas, las autoridades y la población no tomaron las medidas necesarias para modificar los patrones constructivos, materiales de construcción y el ordenamiento territorial con intenciones preventivas a futuro, al mantener e incluso incrementar la vulnerabilidad en la ciudad.

Resumen El proceso de sacrificio es la última etapa de manejo y representa un punto en el que se compromete el bienestar de los bovinos. El objetivo del presente trabajo fue evaluar los indicadores de bienestar animal de bovinos en un rastro Tipo Inspección Federal. Se observó el proceso de sacrificio de 1,167 animales [740 machos (63.8 %) y 420 hembras (36.2 %)] en una planta de sacrificio Tipo Inspección Federal en el noroeste de México. Se registraron variables de manejo y comportamiento, así como indicadores de retorno a la sensibilidad y se caracterizaron los hematomas observados en las canales. El 10 % del ganado recibió descargas eléctricas con picanas, el 24.3 % fue golpeado por los operarios. Se observó arqueamiento de la columna vertebral (44.5 %), el 62.2 % de los animales mostró sensibilidad durante el sangrado. La prevalencia de hematomas fue del 88.8 %. Las hembras tuvieron 1.62 mayor riesgo de sufrir hematomas que los machos y la presencia de cuernos grandes incrementó el riesgo de presentar hematomas 1.46. Las características de los hematomas observados fueron rojo brillante (93.8 %), moteado (71.5 %), pequeño (82.9 %) y grado 1 (95.7 %). La zona más afectada por hematomas fue la dorso-lumbar con un 58.3 %. Se concluyó que los animales incluidos en el presente estudio estuvieron expuestos a condiciones que propician el estrés, entre estos, el uso de la picana eléctrica por los operarios, las conductas indeseables de los bovinos durante el arreo, el aturdimiento ineficaz y la presencia de hematomas en las canales.

Abstract The slaughter process is the last stage of management and represents a point at which the welfare of the cattle is compromised. The objective of this study was to evaluate the animal welfare indicators of cattle in a Federal Inspection Type slaughterhouse. The slaughter process of 1,167 animals [740 males (63.8 %) and 420 females (36.2 %)] was observed in a Federal Inspection Type slaughter plant in northwestern Mexico. Management and behavioral variables, as well as indicators of return to sensitivity were recorded, and the bruises observed on the carcasses were characterized. 10 % of the cattle received electric shocks with prods, while 24.2 % were beaten by operators. Arching of the spine was observed (44.5 %), 62.2 % of the animals exhibited sensitivity during exsanguination. The prevalence of bruising was 88.8 %. Females had 1.62 % higher risk of bruising than males and the presence of large horns increased the risk of bruising by 1.46 %. The characteristics of the bruises observed were bright red (93.8 %), mottled (71.5 %), small (82.9 %), and grade 1 (95.7 %). The area most affected by bruises was the dorsal-lumbar area, with 58.3 %. It was concluded that the animals included in this study were exposed to conditions conducive to stress, including the use of the electric prod by the operators, undesirable behaviors of cattle during herding, ineffective stunning, and the presence of bruises on the carcasses.

Resumen El daño cerebral adquirido es un tema de central interés en la neuropsicología, puesto que nos permite comprender la relación entre la cognición, comportamiento y emoción con el funcionamiento cerebral patológico. En esta oportunidad, presentamos un caso con una enfermedad cerebrovascular que, producto de un daño a nivel talámico, presenta alteraciones ejecutivas, emocionales, lingüísticas y mnésicas. Se trata de un paciente de 52 años de edad que presenta signos y síntomas como una despreocupación personal, falta de motivación por buscar empleo, problemas en la regulación de su comportamiento, entre otros. Analizamos el caso en torno al rol del tálamo en el funcionamiento cerebral global y en la necesidad de realizar un seguimiento correcto con el paciente.

Abstract Acquired brain damage is a topic of central interest in neuropsychology, since it allows us to understand the relationship between cognition, behavior and emotion with pathological brain functioning. On this occasion, we present a case with a cerebrovascular disease that, as a result of damage at the thalamic level, presents executive, emotional, linguistic, and memory disorders. This is a 52-year-old patient who presents signs and symptoms such as personal insouciance, lack of motivation to seek employment, problems regulating his behavior, among others. We analyze the case regarding the role of the thalamus in global brain functioning and the need to carry out a correct follow-up with the patient.
