Purpose – The purpose of this article is to assess the effect of religious fasting on the cognitive performance during the month of Ramadan among healthy fasting individuals. Design/methodology/approach – 30 students were recruited prior the month of Ramadan to compare their cognitive performance during and after fasting. The data on cognition

Luvunga scandens (“Mengkurat Jakun”) is one of the medicinal plant that produce triterpenoid compounds. A number of studies have reported that the compounds possess antiproliferative activities against various type of cancer cells. The present study aims for anticancer potential of two triterpenoids derived from L. scandens namely flindissol (c

There is a growing interest in bioethanol as biofuel since it has the possibility to be the potential substitute for fossil fuels. Ethanol batch fermentation of Saccharomyces cerevisiae strain was carried out in 10 L stirred tank bioreactor for 72 h at 0.075 vvm of aeration and 75 rpm of agitation speed. 85.8% conversion efficiency of ethanol produ

Purpose: The aim of this qualitative paper was to understand the employment needs of young adults with visual disability in Kabul, Afghanistan. Method: The phenomenological approach was employed to obtain rich data based on the participants’ personal experiences. In-depth semi-structured interviews were conducted with 14 adults with visual disabi

Quartz crystal oscillators is widely used in many types of electronics equipment for our daily life applications such as mobile communication, military, industrial measurement, an others due to its high stability clock sources. In this paper, a Two-Stage CMOS op-amp for a quartz crystal-based oscillator is presented. The design of two-stage CMOS op

This paper investigates the perplexing issue of the democratic deficit in Africa's postliberation states. It seeks to answer why former African liberation movements failed to make a genuine transition to democracy during the second stage of the national liberation struggle, instead ofleaving behind authoritarian military regimes and one-party s

Recently, Plug-in Hybrid electric vehicles become a sustainable solution to strike a balance between performance and fuel economy. For a multimode PHEV, the car switches among three operation modes; namely electric mode, series mode, and parallel mode to maximize fuel economy based on the driving conditions. Atkinson thermodynamic cycle has a highe

The supply chain group consists of members from various locations in the network working together to deliver services to the client. Integration challenges remain as main issue for the group to create more flexible processes and allow modification to be made to the current and global pre-planned processes for the entire supply chain members in the

The influence of dispersant concentration on the physical properties of porous alumina ceramics formed by the protein foaming–consolidation method has been studied. Slurries of alumina powders, yolk, and dispersant were prepared by rigorously stirring the mixture for 3 h with an alumina-to-yolk ratio of 1 : 1 in weight and dispersantconcentration

The future integrated circuit would demand a combination of micromechanical components and traditional electronics. MEMS resonator is the one of future integrated circuit. MEMS resonators can provide CMOS compatibility and multifrequency operation on a single chip. In this paper, Two-Stage CMOS op amp for a MEMS-based oscillator is presented. The d
