Abstract Background Serious measures, including mass vaccination, have been taken to ensure sufficient hospital capacity during the COVID-19 pandemic.Due to high hospitalization risk in the oldest age groups, most countries prioritized elderly for vaccines.The aim of this study is to broaden the understanding of how vaccination in younger age group
The world-wide cement industry is seeking experimental avenues that will lead to cement production that is less energy-intensive, less damaging to the surrounding environment and less prolific in GHG emissions.In Spain and Europe in general, this approach is wholly consistent with the concept of sustainability and compliance with the Kyoto Protocol
The type of aluminosilicate precursor used in the synthesis of geopolymer binders plays a huge role in the resulting performance.Thus, it is critical to understand the properties of precursors and how they influence the corresponding performance of geopolymer binders.In this study, metakaolin and meta halloysite are used as the aluminosilicate prec
Abstract Precise characterization of geomaterials improves subsurface energy extraction and storage.Understanding geomaterial property, and the complexities between petrophysics and geomechanics, plays a key role in maintaining energy security and the transition to a net zero global carbon economy.Multiple sectors demand accurate and rapid characte
The semi-analytical solution for transient electroosmotic flow through elliptic cylindrical microchannels is derived from the Navier-Stokes creative grids quick trim and circle ruler equations using the Laplace transform.The electroosmotic force expressed by the linearized Poisson-Boltzmann equation is considered the external force in the Navier-St
