The catalysis and characterization of carbon nanofibers (CNFs) composite are reported in this work. Carbon nanofibers were produced on oil palm shell powdered activated carbon (PAC), which was impregnated with nickel. Chemical Vapor Deposition (CVD) of C2H2 was used in the presence of hydrogen at ~ 650º C. The flow rates of carbon source and hydro

Lightweight block cipher algorithms are vital for constrained environment. There are three factors should be considered when you design lightweight block cipher algorithm which are security, performance and cost. In this paper, we have improved the cost factor of OLBCA algorithm by decreasing the number of Substitution box (S-box) without a major e

Carbon nanofibers (CNFs) were synthesized through nickel ion (Ni2+) impregnation of powdered activated carbon (PAC). Chemical Vapor Deposition (CVD) using acetylene gas, in the presence of hydrogen gas, was employed for the synthesis process. Various percentages (1, 3, 5, and 7 wt. %) of Ni2+ catalysts were used in the impregnation of Ni2+ into PAC

Relaxation and calmness are two emotions that people continually seek. One popular method people frequently use to reduce their tension and pressure levels is listening to various types of relaxing music. However, the Quran is composed of Allah’s words, which were ultimately given for the benefit of humanity. Muslims strongly believe that listeni

The quality of service plays a vital role in any service-related economic sector, including in the banking services industry. While the service sector is a major contributor to economic activity,in-depth study on service quality and its impact on customer satisfaction have been largely overlooked. Moreover, all organizations seek quality, particula

LTE is expected to be the dominant system used by operators in these years due to its promising solutions for achieving high capacity and data rate. However, LTE packet scheduling and distributing resources among users is still the main challenge due to unfairness and low performance which occur when allocating resources to users. In this paper, th

Micro gap heat sinks reduce flow boiling instabilities and generate more uniform surface temperature than typical microchannels. Heat transfer rate in micro gaps can be increased by providing micro fins. Micro fins increase surface area as well as generate turbulence, which disturbs the laminar sub-layer. Hence, heat transfer rate enhances due to r

Leaves of Tetracera indica are used in traditional medicine for the treatment of diabetes mellitus in Malaysia. This study was aimed at investigating the phytochemical constituents present in T. indica leaves which may be responsible for the antidiabetic effect of the plant’s leaves. Crude methanolic extract from the leaves of T. indica was separ

Introduction: Leaves of mempelas paya (Tetracera indica) (family: Dilleniaceae) is traditionally used in diabetes management in Malaysia. However, no attempt has ever been made to discover an active principle responsible for its blood glucose lowering effect. Hence, this research deals with the isolation, in vivo antidiabetic and toxicological eval
