INTRODUCTION: rubella cases are often under-reported, especially in many developing countries, owing to inadequate attention and weak funding of elimination strategies, despite being an epidemic-prone disease.Therefore, the paper seeks to bring attention of public health practitioners, researchers and policy makers to threats of rubella and recomme
In this paper, we present a harmonic reaction inductive folded dipole antenna (FDA) for a highly efficient rectenna which is close to the fundamental limitation on efficiency.To remove lossy RF circuit components of the rectifier, the proposed antenna topology integrates circuit functionalities for highly efficient rectification, such as impedance
Angola is a coastal west-central African state which currently stands as one of the fastest growing economies on the sub-continent.Angola’s development as a burgeoning economic powerhouse has been attained despite a protracted and brutal civil conflict spanning several decades.In the current post-conflict era, Angola has emerged as one of the
This paper describes a three-layer head phantom with artificial pulsating arteries at five different depths (1.2 mm, 3.7 mm, 6.8 mm, 9.6 mm and 11.8 mm).The structure enables formation of spatially and temporally varying tissue properties similar to those of living tissues.In our experiment, pressure pulses were generated in the arteries by an elec
