In high-temperature applications of ferrous materials, as in the case of exhaust manifolds, high thermal and mechanical stability are required. Stainless steels and Ni-resist alloys having austenitic matrices are good candidates to meet these requirements at elevated temperatures; however, they are expensive materials and present difficulties in casting. Ferritic ductile cast irons, like the commercial SiMo alloy, are comparatively cheaper materials with better castability but they cannot be used above approximately 800 °C. Thus, to meet the requirements with low-cost materials having improved high-temperature properties, new alloys must be developed by ferrite forming elements having the potential to increase equilibrium temperature. In this study, initially, a novel ductile cast iron matrix was designed using 1 W and 0-4 Al wt.-% and their phases stable at room temperature, transformation temperatures, solidification sequences and thermal expansivity values were determined using thermodynamic calculations with Thermo-Calc software. Computational studies revealed that (i) designed alloy matrices had graphite and M6C type carbides embedded in a ferritic matrix at room temperature as expected, (ii) A1 temperature increased as aluminum content increased. The obtained values were all above that of commercial SiMo alloy, (iii) the detrimental effect of increased aluminum addition on graphite content, and thermal expansivity was observed. Secondly, microstructural and thermal characterizations of cast alloys were performed for validation – the obtained data were in good agreement with the thermodynamic calculations.

Published: April 2020

In this study, the effect of non-metallic inclusions (NMIs) on tensile behavior of titanium stabilized Fe-20Cr-9Ni steel was investigated. The size of NMIs was decreased via the electro-slag remelting (ESR) process. JK-inclusion rating method revealed that the studied steel consisted of D-type (square-shaped) inclusions. According to energy dispersive spectroscopy, it was determined that the appeared inclusions in the matrix of the titanium stabilized Fe-20Cr-9Ni steel is predominantly titanium nitride (TiN). As a result of the ESR process, excellent improvement in the tensile properties of the studied steel was observed. Subsequently, the effect of inclusion size (d = 5, 10, 25, 50 µm) and orientation (α = 0, 45°) on stress concentration factor around the non-metallic inclusion and metallic matrix was simulated. The result of finite element analysis indicated that, for both square (α = 0 °) and rhombus (α = 45°) shape inclusions, increasing inclusion size has resulted in high-stress concentration factor during plastic deformation. On the other hands, generated Mises stress field around the non-metallic inclusion presented that, for the same inclusion size, rhombus (α = 45°) shape inclusion is more susceptible to homogenous deformation in comparison with square (α = 0°) one.

Authors: Liantoni Febri , Agusti Arif
Published: April 2020

Abstractâ€” After being introduced in 2008, the rise in the price of bitcoin and the popularity of other cryptocurrencies triggered a growing discussion about how much energy was consumed during the production of this currency. Making cryptocurrency the most expensive and most popular, both the business world and the research community have begun to study the devel-opment of bitcoin. In this study bitcoin price predictions are performed using the double exponential smoothing method based on the mean absolute percentage error (MAPE). The MAPE value is used to find the best alpha (Î±) parameter as the basis for bitcoin price forecasting. The dataset used is the price of bitcoin from 2017 to 2019. The dataset was obtained from www.cryptocompare.com. As for the value of the alpha parameter (Î±), using a value of 0.1 to 0.9. Based on the test results using the double exponential smoothing method obtained the smallest MAPE value of 2.89%, with the best alpha (Î±) at 0.9. The prediction is done to see the price of bitcoin on January 1, 2020. The error rate generated on the predicted price of bitcoin uses an amount of 0.0373%. This shows that the system built can be used as a support for decision making when trading bitcoin.

Authors: Martin Roger , Sierra-Ruiz Melibea
Published: April 2020

Es grande la expectativa que genera en todos los servicios de salud del mundo la rápida expansión del SARS-CoV2 (Coronavirus 2 del Síndrome Respiratorio Agudo y Grave), agente etiológico de la Enfermedad Infecciosa por Coronavirus del año 2019, COVID-19. Por tratarse de una enfermedad emergente es poco lo que se conoce sobre su comportamiento en los humanos, lo que lleva a múltiples interrogantes al momento de tomar decisiones en la práctica clínica. Hasta el momento, las estrategias para enfrentar esta pandemia se basan en la experiencia de los países que han sido epicentro del brote infeccioso y en la evidencia recopilada durante el manejo de otros coronavirus en años anteriores (SARS-CoV en el año 2002 y MERS-CoV en 2012).
La falta de información contundente y unificada ha dado lugar a especulaciones y a suposiciones, especialmente relacionadas con la atención del COVID-19 en poblaciones consideradas de alto riesgo, como son los pacientes crónicamente inmunosuprimidos postrasplante. A través de esta revisión narrativa de la literatura, más allá de dar la opinión de los autores, se pretende organizar de manera juiciosa los documentos hasta el momento publicados, y responder, basados en datos reales, cinco de las preguntas más importantes que surgen en el día a día durante el manejo de los pacientes trasplantados.
