Research ArticleOpen accessIn the abstractThe Induction of Lycopene in Germinating Cottonseed with 2-(4-Methylphenoxy) Triethylamine (MPTA)Lorraine S. Puckhaber, Jinggao LiuAbstract: Problem Statement: Increasing carotenoids content in foods was currently of great interest. The present paper reports strong stimulatory effect of MPTA on the carotenogenesis in cotton, which was used as a model. Approach: Cotton seedlings were treated with MPTA vs. water and germinated in the dark. The levels of carotenoids were determined by HPLC and the expression levels of … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 26 Jul 2011 · 7,950 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Milling Time on Ni0.5Zn0.5Fe2O4 Compositional Evolution and Particle Size DistributionI. Ismayadi, M. Hashim, A. M. Khamirul, R. AliasProblem statement: This study involved an investigation to ascertain the diffusion of NiO and ZnO into the tetrahedral and octahedral sites using mechanical alloying method. The effect of mechanical alloying towards particle size was also reported. Approach: NiO, ZnO and Fe2O3 precursors were mechanically alloyed to synthesis ultrafine powders of Ni0.5Zn0.5Fe2O4. Various milling times were employed to study the effect … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,998 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Review: Microbiological, Physicochemical and Health Impact of High Level of Biogenic Amines in Fish SauceMuhammad Zukhrufuz Zaman, A. S. Abdulamir, Fatimah Abu Bakar et al.Problem statement: Biogenic amines are basic nitrogenous compounds present in a wide variety of foods and beverages. Their formations were mainly due to the amino acids decarboxylase activity of certain microorganisms. Excessive intake of biogenic amines could induce many undesirable physiological effects determined by their psychoactive and vasoactive action. Fish sauce which is considered as a good source of dietary … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,915 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIonospheric Total Electron Content Response to the December 26, 2004 North Sumatra EarthquakeA. Abdullah, A. F.M. Zain, M. H. Jusoh et al.Problem statement: Ionospheric precursors of earthquake have been studied by scientists and seismologists. This study aims at examining the relationship between the ionosphere and earthquake precursors. The effects of the anomalous electric field that penetrates the ionosphere on the electron concentration can be measured experimentally. This study reports on the variability of the Total Electron Content (TEC) during the December … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,908 accessesView PDF Cite
