Culture of five species of Malaysia indigenous freshwater microalgae
Published 2016“…The growth of Chlorella can be seen materially faster than any other microalgae strain especially from the strain that has spines such as Scenedesmus sp. TH. Based on the observations available, it appears that smaller strains of unicellular microalgae have appreciably higher intrinsic growth rates than algae of the larger size. …”

Planar antennas with enhanced bandwidth and radiation characteristics
Published 2017“…In this chapter, novel wideband and ultra-wideband (UWB) antennas that are based on loading the background plane of a monopole radiator with concentric split-ring resonators are presented. It is shown that this modification improves the fractional bandwidth of the antenna from 41 to 87%; in particular, the operational bandwidth of the proposed antennas is double that of a conventional monopole antenna of the same size.…”
