This dissertation compared the differences in fertility amongst groups of women with distinct migration status by using two different matching methods: the Propensity Score Matching (PSM) and the Coarsened Exact Matching ...

We study the effect of inter-grid operators—the interpolation and restriction operators—on the convergence of two-grid algorithms for linear models. We show how a modal analysis of linear systems, along with some assumptions ...

MgAl2O4 is a stable catalyst support with potential for replacing gamma-alumina in several applications. However, synthesis of magnesium spinel requires elevated temperatures to avoid phase separation (in MgO and Al2O3) ...

Resumen En el presente trabajo se realizó el estudio de la precipitación y engrosamiento de carburos, así como su efecto sobre las propiedades mecánicas durante el envejecido isotérmico continuo en un acero ferrítico 5% ...

Refractory insulating is used to reduce thermal losses in industrial processes by decreasing the energy transfer rate between regions with distinct temperatures, therefore, increasing the energy efficiency of various ...

RESUMEN: El material de estudio es un acero ferrítico 2.25Cr-1Mo, que basa sus propiedades mecánicas en el endurecimiento por precipitación de carburos finos y homogéneamente distribuidos en la matriz ferrítica; cuando ...

Maraging steels combine ultra-high strength (1500 – 2450 MPa of tensile strength) with excellent toughness (50 – 240 MPa√��) and are widely used in aerospace and military applications. Unlike other high strength steels ...
