Assessment of Microalgae Cell Culture Growth Regulatory Mechanism Towards Different Medium Formulation, Light Intensity and Photoperiod
Research Output | Dar Al-hikmah Library | IIUM Only

The cell culture growth regulatory mechanism for microalgae is depending on various factors such as medium composition, light intensity and photoperiod. Significantly, it will influence economical important through productivity of large scale microalgae for commercialization in order to achieve the maximum growth. In the present study, effects of d

Wear Behaviour of Surface Alloyed Duplex Stainless Steel Containing Sic Ceramic Particles
Research Output | Dar Al-hikmah Library | IIUM Only

This article presents an experimental investigation on the wear behaviour of surface alloyed duplex stainless steel (DSS) containing SiC ceramic particles using TIG melting technique. The SiC powder with 20 µm particle sizes was preplaced at 0.5 mg/mm2 and melting was conducted with energy inputs of 768 and 1280 J/mm. The room temperature wear beh

Key Indicator Tools for Shallow Slope Failure Assessment Using Soil Chemical Property Signatures and Soil Colour Variables
Research Output | Dar Al-hikmah Library | IIUM Only

Slope failure has become a major concern in Malaysia due to the rapid development and urbanisation in the country. It poses severe threats to any highway construction industry, residential areas, natural resources and tourism activities. The extent of damages that resulted from this catastrophe can be lessened if a long-term early warning system to

Influence of Environmental Stress Toward Carotenogenesis Regulatory Mechanism Through in Vitro Model System
Research Output | Dar Al-hikmah Library | IIUM Only

Carotenoid biosynthesis is influenced by some aspects and is liable to geometric isomerisation with the existence of oxygen, light, and heat, which affect color degradation and oxidation. The major problems related to carotenoid accumulation inherently originate from pigment instability. This chapter discusses an overview on the influence of string

Human Location Detection System Using micro-Electromechanical Sensor for Intelligent Fan
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presented the development of sensory system for detection of both the presence and the location of human in a room spaces using MEMS Thermal sensor. The system is able to detect the surface temperature of occupants by a non-contact detection at the maximum of 6 meters far. It can be integrated to any swing type of electrical appliances s

Influence of Growing Location, Harvesting Season and post-Harvest Storage Time on Carotenoid Biosynthesis in Orange Sweet Potato (Ipomoea Batatas) Tuber Flesh
Research Output | Dar Al-hikmah Library | IIUM Only

Carotenoid content in plants differs due to several factors such as cultivar, maturity, climate, locality and storage. Improving the nutritional values of sweet potato is an important breeding goal and understanding the regulation, genetics and inheritance of carotenoid biosynthesis are vital to achieve this. Environmental conditions can have a mar

Slope Failure Analysis Using Chromaticity Variables
Research Output | Dar Al-hikmah Library | IIUM Only

Slope failure has become a major concern in Malaysia due to the rapid development and urbanisation in the country. It poses severe threats to any highway construction industry, residential areas, natural resources, as well as tourism activities. Thus, this study aims to characterise the relationship between chromaticity variables to be manipulated

Human Location Estimation Using Thermopile Array Sensor
Research Output | Dar Al-hikmah Library | IIUM Only

Utilization of Thermopile sensor at an early stage of human detection is challenging as there are many things produce thermal heat other than human such as electrical appliances and animals. Therefrom, an algorithm for early presence detection has been developed through the study of human body temperature behaviour with respect to the room temperat

Stability of Carotenoid Composition in Orange Sweet Potato (Ipomoea Batatas) Tuber Flesh Over Three Growing Seasons and 6 Months Storage Time
Research Output | Dar Al-hikmah Library | IIUM Only

Considerable research interest has recently focused on the development of both transgenic and traditional breeding methods to increase total and individual carotenoid composition in sweet potatoes. Unfortunately little information is available on the influence of the environment on carotenoid profile stability in sweet potatoes especially growing s

Effect of Abiotic Stress on Carotenoids Accumulation in Orange Sweet Potato Callus Under Light and Dark Conditions
Research Output | Dar Al-hikmah Library | IIUM Only

Abiotic stress factors are the main limitation to plant growth and yield in agriculture. Orange sweet potatoes may become major sources of carotenoids in the diet, but the extent of environmental and genetic influences on plant carotenoid biosynthesis are poorly understood. Carotenoid biosynthesis is regulated by several factors such as water, ligh
