Dokumen merupakan instrumen penting dalam kehidupan seharian. Bukan semata-mata sebagai suatu rekod, dokumen juga mempunyai nilai yang tersendiri dan boleh mengandungi pelbagai kepentingan di mata manusia. Apabila menglibatkan rahsia sesebuah negara, dokumen yang mengandungi kerahsiaan tersebut perlu dijaga dengan sebaik-baiknya daripada segi kesel

This study presents the synthesis of a series of methoxybenzoylthiourea amino acid derivatives. The compounds were obtained from the reactions between 2/3/4-methoxybenzoyl isothiocyanate with threonine. All of the compounds were characterized via mass spectrometry, 1H and 13C NMR spectrometry, UV-Vis spectrophotometer and FT-IR spectroscopy. Mass s

This paper presents the effects of Nano-coating process parameters on the thermal efficiency enhancement of copper substrate material. A comparison experimental results of Nano copper oxide coating prepared in oxalate solution at various operating conditions with different porosities and grain sizes. The study evaluate the effects of the Nano coati

The risk of unexpected and harmful events haunted every business that will cost the company money or ultimately brings it to permanently close. Risk management allows organizations to get ready for the unforeseen events by minimizing and avoiding the risks before they happen. The implementation of a successful risk management plan will ensure an or

The changing demographics of higher education due to internationalization has made it incumbent upon educators to promote as well as create multicultural learning environments to meet the challenges of teaching in culturally diverse settings. Studies have shown that teachers’ awareness of multiculturalism will have a direct effect on students’

The development of the velocity gradient at the opening of a closed conduit plays an essential role in monitoring the heat transfer behavior. Hence it is indispensable to examine the minimum critical length at which the velocity gradient is fully developed. Ultimately the flow is fully developed. The developing length determination is very useful f

This paper presents the experimental results of nano copper oxide coating on the heat transfer performance of the copper substrate. The thermal effect of Nano copper oxide coating investigated by using an experimental thermal system consisted of three sections: evaporator, adiabatic, and condenser. The copper oxide (CuO) coating performed for the i

A Q-switched fibre laser operating at 1500 nm is proposed and demonstrated. The laser uses a saturable absorber (SA) based on carbon nanotubes (CNTs) to generate Q-switched pulses, while a 30-m-long depressed-cladding erbium-doped fibre (DC-EDF) provides the necessary gain in the desired wavelength region. The proposed laser has lasing and pulsed t

Youths are very vulnerable to the rapid development of technology specifically on students. The presence of varieties online applications that can be downloaded on their smartphone have exposed them to the latest technology especially in Virtual Reality (VR) technology. Hence, Technology Acceptance Model (TAM) is applied in this study in order to u

Microstrip patch antenna (MPA) having Ultra-Wide Band characteristics is a worthy applicant in wireless communications. Mitigating EMI with the narrowband such as 5G lower band, Wi-MAX, WLAN, Satellite band lies in UWB region is a major research concern. This paper presents an UWB antenna containing variable band rejection for avoiding interference
