Research ArticleOpen accessIn the author namesForecasting Ozone Concentrations Using Box-Jenkins ARIMA Modeling in MalaysiaWan Rozita Wan Mahiyuddin, Nur Izzah Jamil, Zamtira Seman et al.Time series analysis and forecasting has become a major tool in many applications in air pollution and environmental management fields. Among the most effective approaches for analyzing time series data is the model introduced by Box and Jenkins. In this study, we used Box-Jenkins methodology to build Autoregressive Integrated Moving Average (ARIMA) model on the average of monthly ozone data … …American Journal of Environmental Sciences, Vol. 14, Issue 3 · 25 May 2018 · 8,943 accessesView PDFCite
Research ArticleOpen accessIn the author namesRemediation of Heavy Metals by using Industrial Waste by Products in Acid Mine DrainageNuur Hani Mohammed, Mustapha Atta, Wan Zuhairi Wan YaacubAcid Mine Drainage (AMD) is one of the main important problems being combated today. Laboratory tank experiments were conducted to evaluate the use of industry waste to adsorb and control the mobilization of metals from contaminated acid mine water. The main physical conditions such as pH and treatment performance are displayed. The solution of acid mine were sampled from the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 18 Dec 2017 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the author namesMeasuring Hydraulic Conductivity Using Geotechnical CentrifugeNur Aishah Zarime, Wan Zuhairi Wan YaacobThis study investigated the validity of hydraulic conductivity value using Mini Column Infiltration Test. Granitic residual soils from Broga Selangor, Malaysia were tested to obtain the hydraulic conductivity value in relatively shorter time. Soil samples were physically characterized before being tested using Centrifuge Mini Column Infiltration Technique. A normal 1-g Falling Head Permeability Test (Kf) was also being performed as … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 6 Nov 2017 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the author namesDetermination of Breeding Seasonality in Rusa Deer (Rusa timorensis) Stags via Serum Testosterone ProfilingWan Nor Fitri Wan Jaafar, Abd Wahid Haron, Rosnina Hj Yusoff et al.Breeding seasonality in mammals is influenced by the environmental changes and the endocrine response of the animals to that changes. Comprehension in breeding seasonality enables better reproductive management consequently maximizing the reproductive potential of the stags. Despite that, the study in breeding seasonality in Rusa deer (Rusa timorensis) is still scarce. Five healthy and matured stags were selected for this … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 19 Mar 2017 · 8,608 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Social Content Management Model based on the DART ModelWan Azlin Zurita Wan Ahmad, Muriati MukhtarWeb 2.0 has increased the volume of unstructured content which gives rise to the need for a Social Content Management (SCM) model. A review of the literature reveals that research specific in SCM is broad and fragmented. It also highlights the need for a comprehensive SCM model. Due to the specific nature of social content, existing Enterprise Content Management (ECM) … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 31 Dec 2016 · 8,072 accessesView PDFCite
