Research ArticleOpen accessIn the abstractFrequency Behavior of a Quartz Crystal Microbalance (Qcm) in Contact with Selected SolutionsZ. A. Talib, Z. Baba, S. Kurosawa et al.A device was constructed to monitor viscosity of solutions using fundamental frequency of 9 MHz and 10 MHz quartz crystal. Piezoelectric quartz crystals with gold electrodes were mounted by O-ring in between liquid flow cell. Only one side of the crystal was exposed to the solutions which were pumped through silicon tube by a peristaltic pump. The measured frequency shift … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 7,514 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGAUSSIAN COPULA MARGINAL REGRESSION FOR MODELING EXTREME DATA WITH APPLICATIONSutikno, Heri Kuswanto, Iis Dewi RatihRegression is commonly used to determine the relationship between the response variable and the predictor variable, where the parameters are estimated by Ordinary Least Square (OLS). This method can be used with an assumption that residuals are normally distributed (0, σ2). However, the assumption of normality of the data is often violated due to extreme observations, which are often found … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 4 Apr 2014 · 7,620 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification of Volatile Metabolites from Fungal Endophytes with Biocontrol Potential towards Fusarium oxysporum F. sp. cubense Race 4A.S.Y. Ting, S.W. Mah, C.S. TeeProblem statement: Fungal endophytes are widely studied for their potential as biocontrol agents towards fungal pathogens. In vitro assessments usually reveal their antibiosis and mycoparasitism nature, but little is understood regarding their production of volatile metabolites as mechanisms of antagonism. Approach: This study explored the potential of fungal endophytes in controlling the pathogen responsible for Fusarium wilt disease. Nine fungal … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 11,872 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Crude Aqueous Extract of Piper betle L. and its Antibacterial Effect Towards Streptococcus mutansT. Nalina, Z.H.A. RahimIn this study, the antimicrobial influence of crude aqueous extract of Piper betle L. on Streptococcus mutans (S. mutans) was investigated. The focus of the antimicrobial effects includes the ultrastructure and acid producing properties of S. mutans. Transmission electron microscopy (TEM) was used to determine the effect of the extract on the ultrastructure of S. mutans. Analysis of the effect … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 13,459 accessesView PDF Cite
