A number of media components influencing a-amylase production by Aspergillus niger O103A were studied using local bitter variety of cassava (Manihotes cuelenta) as the main substrate. The media components (cassava, maltose, glucose, yeast extract, urea, NH4NO3, KH2PO4, CaCl2, MgSO4.7H2O, NaCl, and FeSO4.7H2O) were analyzed using Plackett?Burman des

At a frequency range above 5 GHz, rainfall becomes a serious and major source of attenuation for microwave communication. Atmospheric effects play a major role in designing terrestrial or satellite-to-earth links operating at frequencies above 5 GHz. Raindrops absorb and scatter radio waves, leading to signal attenuation and reduction of the system

This paper presents the application of time weighted model reduction using cross gramians on a state space model derived from two partial differential equations representing the instantaneous thermal balance of a differential element of length along the absorber plate and the absorber plate to fluid heat convection process respectively of a flat pl

Recent developments have shown that sukuk (Islamic bond) is one of the most noteworthy driving forces behind the growth of the Islamic capital market and Islamic finance as a whole. Unlike conventional bonds, sukuk offers the investor ownership of tangible assets, usufruct of an asset, or sometimes ownership of certain projects or investment activi

The needs for effective and efficient public transportation services are crucial to attract more people to use public transport, hence overcoming the issue of traffic congestion. Public transportation in Malaysia, including KTM Komuter, also facing various challenges, hence cannot offer the quality of services desired by passengers. This study aims

This paper provides an overview of carbon nanotubes (CNTs). The fundamental relations leading the geometry of carbon nanotubes are reviewed and explicit examples are presented. A framework is given for the symmetry properties of carbon nanotubes. The implications of symmetry on the electronic structure of 1D carbon nanotube systems are considered.

The suitability of previously proposed techniques claim to be able toaccurately convert precipitation intensity statistics at longer integration times into 1-minute integration time statistics has been of great interest to many wirelesspropagation researchers. Measured data of precipitation intensity collected in KualaLumpur, Malaysia had enabled t

The Halal Industry is the fastest growing global business across the world although it is a new growing sector. Due to its hygienic, good quality, wholesome and contamination free principles it is a highly demanded emerging market force attracting not only Muslims but also non-Muslims around the world. Currently the halal food industry is estimated

This paper presents assessments of ITU’s predicted rainfall intensities against measurements acquired from a campaign in Kuala Lumpur, Malaysia. Data for a period of twenty months were collected between 1996 and 1998. The statistical analyses involve generation of annual cumulative distributions. Predicted values generated using established ITU-

As steel consumption increases, Malaysia’s steel production will increase, causing escalation in raw material consumption. Malaysia has no iron ore deposit, the low grade ore is an attractive alternative as a domestic iron resource. However, the use of low grade iron ore requires extra energy consumption. Development process for the utilization o
