Flood-prone areas are associated with hydrological time series data such as rainfall, water level and river flow. The possibility to predict flood is to relate all the three data involved. However, in order to develop a multivariable prediction model based on chaos approach, each datum needs to identify chaotic dynamics. As such, the Sungai Galas, Dabong in Kelantan, Malaysia which is a flood disaster area has been selected for the analysis. Rainfall, water level and river flow data in this area were collected to be analysed using the Cao method to identify the presence of chaotic dynamics. The hydrological data is uncertain, which is difficult to predict because the data involved is located in the area of flood disaster. The analysis showed the presence of chaotic dynamics on rainfall, water level and river flow data in the Sungai Galas which involved uncertain data located in flood affected areas by using Cao method. Therefore, a multivariable flood prediction model can be implemente.....

Due to their role as a centre of knowledge and character development,public higher education institutions serve as the best platform for emphasising health communication messages and promoting a healthy lifestyle. Higher educational institutions’ employees should have good physical and mental health to enable them to demonstrate good values to the students. Thus, the social cognitive theory (SCT) was specifically selected to take a close look at how a conducive environment and knowledge influence employees’ intention towards the tobacco-free policy. This study used the partial least squares (PLS) and structural equation modelling (SEM) software to examine factors influencing the adoption of tobacco-free policy among employees in a Malaysian higher education institution. It also measured the impact of workplace health promotion on employees’ intention to comply with tobacco cessation regulations. Statistical results confirmed that all three constructs of employees’ environment, .....

The study was conducted to investigate the effects of Aquilaria malaccensis leaves aqueous extracts on the aphrodisiac properties, which included; sexual behaviour, orientation activity, and testosterone level in ICR mice. Thirty healthy and sexually experienced male and thirty non-estrous female mice were used. In this experiment, each male was cohabitated with one female in a polysulfone cage. The mice were divided into 6 groups that received normal saline (control group), 50 mg/kg, 100 mg/kg, 200 mg/kg, 500 mg/kg, and 1000 mg/kg body weight of A. malaccensis leaves aqueous extract orally for 21 days consecutively. Results showed that all aphrodisiac parameters investigated in this study were similar between the treatment groups to the control group. However, two treated groups that received 100 mg/kg (day 14; day 21) and 200 mg/kg (day 0; day 21) resulted in significantly higher in mount frequency as compared to the control group. Overall, the results revealed that A. malaccensis le.....

This study aims to isolate and identify microalgae capable of growing in high nitrate (NNO3-) landfill leachate. Source of isolation was collected from a landfill leachate treatment plant and identified according to morphological characteristics and analysis of partial 18S and 28S rRNA genes. The isolates, identified as Chlorella vulgaris UPSI-JRM01 and Tetradesmus obliquus UPSI-JRM02 were capable of growing at high N-NO3 - concentration of nitrified landfill leachate, which is up to 1500 mg/L. The biomass productivities of Chlorella vulgaris and Tetradesmus obliquus were 36.28 mg/L/day and 40.49 mg/L/day, with 44% and 37% N-NO3- removal, respectively. The biomass of Chlorella vulgaris and Tetradesmus obliquus consisted of 17.72% and 16.32% lipid and, 21.93% and 25.43% carbohydrate, respectively. The protein contents (>50%) were higher than lipid and carbohydrate contents for both microalgal species. The newly isolated microalgae species will be useful for future applications of high N.....
