Title A name given to the resource Particulate Matter Short-Term Exposition, Mobility Trips and COVID-19 Diffusion: A Correlation Analyses for the Italian Case Study at Urban Scale Creator An entity primarily responsible for making the resource Armando Cartenì, Furio Cascetta, Luigi Di Francesco, Felisia Palermo Description An account of the resource The conjecture discussed in this paper was that the daily number of certified cases of COVID-19 is direct correlated to the average particular matter (PM) concentrations observed several days before when the contagions occurred (short-term effect), and this correlation is higher for areas with a higher average seasonal PM concentration, as a measure of prolonged exposure to a polluted environment (long-term effect). Furthermore, the correlations between the daily COVID-19 new cases and the mobility trips and those between the daily PM concentrations and mobility trips were also investigated. Correlation analyses were performed for the application case study consisting in 13 of the main Italian cities, through the national air quality and mobility monitoring systems. Data analyses showed that the mobility restrictions performed during the lockdown produced a significant improvement in air quality with an average PM concentrations reduction of about 15%, with maximum variations ranging between 25% and 42%. Estimation results showed a positive correlation (stronger for the more highly polluted cities) between the daily COVID-19 cases and both the daily PM concentrations and mobility trips measured about three weeks before, when probably the contagion occurred. The obtained results are original, and if confirmed in other studies, it would lay the groundwork for the definition of the main context variables which influenced the COVID-19 spread. The findings highlighted in this research also supported by the evidence in the literature and allow concluding that PM concentrations and mobility habits could be considered as potential early indicators of COVID-19 circulation in outdoor environments. However, the obtained results pose significant ethical questions about the proper urban and transportation planning; the most polluted cities have not only worst welfare for their citizens but, as highlighted in this research, could lead to a likely greater spread of current and future respiratory and/or pulmonary health emergencies. The lesson to be learned by this global pandemic will help planners to better preserve the air quality of our cities in the post-COVID-19 era.

It could be possible to give priority to the factors that take placein a production process of biological products plants, according to the new tendency in maintenance. Atypical installation is described and also the factors, of such plants, that have to be considered. All theseresults must be compared by using a matrix, taking into account all the factors that interfere in the criticismand complexity of the installation. That was done by well experience engineers and experts. The modelwas validated using expert methods obtaining satisfactory results.Key words: biological products, critical index, critical models, asset hierarchy, asset maintenance.

Title A name given to the resource Análisis de la estabilidad del arado FDN" de tracción animal" Creator An entity primarily responsible for making the resource Armando Eloy García de la Figal Costales, Fidel Diego Nava Description An account of the resource Para el análisis por los métodos de la estática de un arado de tracción animal, modelo FDN-fabricado en Oaxaca, México, se emplea un sistema de fuerzas en el plano longitudinal-vertical de movimiento, aplicado en puntos específicos del órgano de trabajo del mismo, a 1/3 y 1/4 de su profundidad de trabajo, cuyos valores varían de 440 a 1 200 N y de 20 a 260 N para la fuerza horizontal Rx y la vertical Rz, respectivamente y se conocen sus dimensiones, peso, centro de gravedad y punto de aplicación del tiro, el cual está inclinado ß de 200 y 180 respecto a la horizontal. Los resultados demuestran que para las condiciones antes señaladas, dicho arado de tracción animal puede estar en equilibrio estático -como primer principio de la estabilidad de los sistemas móviles planteado por Lyapunov- si se regulan o verticalmente el punto donde se acopla el arado al pértigo o timón, o la longitud del brazo del órgano de trabajo respecto al bastidor del arado, o ambos. Los desplazamientos verticales necesarios calculados varían en: desde 49,39 hasta 163,33 mm, para cuando ß=180 y de 11,16 a 128,24 mm para ß=200. La no realización de lo anterior, implicaría que el bastidor del arado giraría un ángulo ? de 4,760 a favor de las manecillas del reloj, hasta-1,020 en contra, para ß=180 y de 2,760 a favor, hasta -1,50 contrario a las manecillas del reloj, para ß=200.

Title A name given to the resource Análisis resistivo de un nuevo arado de tracción animal mediante el Método de Elementos Finitos (MEF) Creator An entity primarily responsible for making the resource Armando Eloy García de la Figal Costales, Miguel Herrera Suárez, Fidel Diego Nava, Jaime Ruiz Vega Description An account of the resource La tracción animal como fuente energética tiene una amplia utilización en la agricultura de Oaxaca, México. Por tal razón se desarrolló un nuevo arado de tracción animal para realizar las distintas operaciones que se requieren durante la labranza. Con fines de la optimización se hizo necesario analizar la resistencia de los elementos estructurales de dicho arado mediante el método de elementos finitos. Como primer paso se desarrolló el modelo geométrico con la herramienta computacional Cosmos DesingStar 2008, y la definición de las propiedades mecánicas de los materiales empleados en la construcción del arado, así como la definición de las condiciones de borde y cargas. Los resultados mostraron que la estructura resiste las cargas aplicadas durante el trabajo con un coeficiente de seguridad de 2,46, la magnitud de las deformaciones resultantes se limitaron a 0,0005 m. Se evidencia que los materiales empleados en la construcción del arado garantizan la resistencia y rigidez requerida para el trabajo sin fallos de sus elementos y órganos de trabajo.

Estudio de caso: Granja Guayabal, San José de las Lajas, La Habana, Cuba Creator An entity primarily responsible for making the resource Armando Eloy García de la Figal Costales, Roberto González Valdés, Yanoy Morejón Mesa, Dianne Morales Rodríguez Description An account of the resource El presente trabajo se realizó en la finca 'Guayabal', área docente y de investigación del Instituto de Ciencia Animal (ICA), Provincia La Habana, Cuba, con el objetivo de realizar una evaluación energética comparativa de la labor de rotura del suelo Ferralítico Rojo con tracción motorizada (tractor MTZ-510+arado ADI-3) y tracción animal (yunta+arado criollo #2), el estudio se desarrolló para 1 ha de tierra, determinándose la productividad de ambos métodos de rotura, obteniéndose un valor de 0,24 ha/h para la tracción motorizada y de 0,05 ha/h para la tracción animal. Se utilizaron métodos establecidos por diversos autores y la ecuación racional de tiro propuesta por Goriachkin, V. P., obteniéndose un gasto total de energía: con tracción motorizada de 1278,91 MJ/ha; con tracción animal de 1213,23 MJ/ha. La eficiencia energética de la energía directa con respecto a la energía secuestrada total en la motorizada es de 9,57 % y la animal de 5,6 %, y la eficiencia energética de la energía directa respecto a la energía gastada a partir de la suministrada en la tracción motorizada es de 11,38 % y con tracción animal es de 7,09 %. Sin embargo, la energía secuestrada total por m3 de volumen roturado para una ha es 21,22 % mayor para el tiro animal que para el motorizado. Se incluye el análisis económico teniendo en cuenta los costos de inversión, depreciación, mantenimientos, reparaciones y de las diferentes fuentes de energía, obteniéndose un costo total en la labor de rotura con tracción animal superior a la tracción motorizada en 78,10 peso.

El ensayo se realizó durante la época de Postrera (Septiembre - Diciembre) de 1989, en la Finca Experimental La Compañía, Carazo, Nicaragua; sobre un suelo franco - arenoso derivado de cenizas volcánicas (Typic Durandepts). Se utilizó un experimento Bifactorial en diseño de parcelas divididas en Bloques completos al azar, con cuatro réplicas. Los AO empleados fueron Gallinaza, Compost y Pulpa de café, siendo las dosis ensayadas de 5, 10 y 15 ton.ha-1 de cada uno, combinadas con Fosfato Diamónico a razón de 64.8 kg.ha-1. Se observó una disminución de la d y un aumento del EPT con la aplicación de los AO, siendo este efecto influido por las dosis incorporadas. Las parcelas que presentaron la menor d y el mayor EPT, fueron aquellas donde se incorporó el Compost.
