Estudios de la climatología en Quintana Roo (México) y su posible correlación con el consumo de energía eléctrica (Parte II)

CIES2020 - XVII Congresso Ibérico e XIII Congresso Ibero-americano de Energia SolarRESUMEN: El desarrollo de este artículo es sobre el estudio climatológico de diez zonas en las cosas del estado de Quintana Roo, en el Caribe Mexicano, El objetivo de este trabajo es analizar el comportamiento de los cambios ambientales observados recientemente en el Caribe, así como los rápidos aumentos en las temperaturas de la superficie del mar y que se atribuyen al calentamiento global, además el análisis de los consumos de energía eléctrica en las zonas estudiadas. Los datos de temperatura han sido recolectados de diez estaciones meteorológicas en un periodo de 1990 al 2018, así mismo, se han obtenido los datos de consumo de energía eléctrica, en un periodo de 2002 al 2017, con ello se pretende buscar si existe asociación entre las dos variables, además, con el conjunto de datos se va a comprobar con la prueba de ajuste de bondad Chi cuadrada si son estadísticamente significativos o no significativos, es decir, la cual nos demuestra que las variables disponibles representan razonablemente los datos que uno esperaría encontrar. Finalmente, en este trabajo se realizarán los mapas correspondientes para el análisis estadístico de las variables de temperatura durante un periodo de 1990 hasta 2018.ABSTRACT: The development of this article is about the climatological study of ten zones in the things of the state of Quintana Roo, in the Mexican Caribbean, The objective of this work is to analyze the behavior of the environmental changes recently observed in the Caribbean, as well as the rapid increases in sea surface temperatures attributed to global warming, in addition to the analysis of electrical energy consumption in the areas studied. The temperature data have been collected from ten meteorological stations in a period from 1990 to 2018, likewise, the data on electricity consumption have been obtained, in a period from 2002 to 2017, with this it is intended to find if there is an association between The two variables, in addition, with the data set, it will be verified with the Chi-square goodness adjustment test if they are statistically significant or not significant, that is, which shows us that the available variables reasonably represent the data that one would expect find. Finally, in this work the corresponding maps will be made for the statistical analysis of the temperature variables during a period from 1990 to 2018.info:eu-repo/semantics/publishedVersio

Impact of COVID-19 on Cardiovascular Testing in the United States Versus the Rest of the World

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-U.S. institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
