Data transparency has played a key role in this pandemic.The aim of this paper is to map COVID-19 data availability and accessibility, and to rate their transparency and credibility in selected countries, by the source of information.This is used to identify knowledge gaps, and to analyse policy implications.The availability of a number of COVID-19
In recent years, as environmental protection requirements have expanded, SF6/N2 mixed gases have been selected as an insulating medium for high-voltage equipment such as GIL (gas insulated transmission line) without undertaking breaking tasks, which is superior in terms of insulation, economy and environmental protection.The development of streamer
In this study, a novel methodology for the fabrication of gradient porous structures is introduced, predicated upon the phase evolution characteristics of immiscible polymer blends.Initially, a comprehensive flow-phase field dynamics model is developed.This model couples the principles of phase field theory and the dynamics of fluid flow to the two
The COVID19 pandemic has significantly impacted scientific research and higher education.With the chaos, confusion, Brain and Liver and concern caused by the SARSCoV2/COVID19 pandemic, there are lots of questions and general curiosity about coronaviruses and infectious disease.This global health crisis provides an optimal platform for teaching and
We consider Harmonic Functions, H of several variables.We obtain necessary and sufficient conditions on its Fourier coefficients so that H is an entire harmonic (that is, has no finite singularities) function; the radius of gen harmonicity in terms of its Fourier coefficients in case H is not entire.Further, we obtain, in terms of its Fourier coeff
