The regional ionosphere maps over Malaysia were studied during the minimum phase of solar cycle 23. Fifty-seven GPS RTK reference stations for the network covering the whole of Malaysia managed by JUPEM were used in this analysis. TEC is the measure of the number of electrons along the path from the satellite and is reported as TEC Units (1 TECU = 1??1016 electrons). The observations of oblique TEC...
The ionosphere layer is very important to the communication system. This research involves the determination of total electron content (TEC) in ionosphere based on height in order to determine the appropriate TEC value for Malaysia and for the equitorial region generally. The ionospheric model used is the single layer model based on the Bernese GPS 5.0 Software. The ionosphere TEC map of Malaysia...
This study presents the first experimental evidence of the sensitivity of rice plants to ambient air pollution from the Southeast Asian tropical region. Two widely adopted local cultivars of rice (Oryza sativa L.), MR84 and MR185, were grown in open top chambers ventilated with charcoal-filtered air and non filtered air, and in adjacent open plots on the campus of University Putra Malaysia. This is...
