Research ArticleOpen accessIn the abstractDynamics of Coherent Structures in the Coupled Complex Ginzburg-Landau EquationsTat-Leung YeeProblem statement: In this study, we study the analytical construction of some exact solutions of a system of coupled physical differential equations, namely, the Complex Ginzburg-Landau Equations (CGLEs). CGLEs are intensively studied models of pattern formation in nonlinear dissipative media, with applications to biology, hydrodynamics, nonlinear optics, plasma physics, reaction-diffusion systems and many other fields. Approach: A system of two … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 6 Nov 2012 · 6,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Curcumin Based Ophthalmic FormulationD. Anjana, K. Anitha Nair, N. Somashekara et al.Problem statement: Ophthalmic drug delivery system has been a major challenge due to the distinctive and unique anatomy of the eye. The use of phytochemicals for the application in ocular disease has not been investigated much, due to poor pharmacokinetics of phytochemical and hence poor therapeutic efficacy. Approach: Curcumin is one such phytochemical known for its medicinal properties, but its … …American Journal of Infectious Diseases, Vol. 8, Issue 1 · 24 Feb 2012 · 15,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractRegionalism in East Asia: The Role of North East Asian NationsFithra Faisal HastiadiProblem statement: For the past few years, regionalism has been progressing in East Asia with the likes of China, Japan and Korea (CJK) as the most prominent actors. Unfortunately, with the absence of trade arrangement amongst the CJK, the present regional trade scheme is not sufficient to reach sustainability. Thus, the study aims to give the solution to the problem. … …American Journal of Economics and Business Administration, Vol. 3, Issue 2 · 7 Apr 2011 · 6,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Earthquake Demolition Debris on the Quality of GroundwaterM. S. Benmenni, K. BenrachediProblem statement: Debris from construction or demolition/deconstruction processes have no significant impact on the environment as they are res-usable and inert. This has been also long admitted for solid waste generated by the demolition of damaged cities following violent earthquakes. Approach: This study is a contribution to the assessment of actual impact on the quality of groundwater of buried demolition … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,236 accessesView PDFCite

Ng, S. A. Halim et al.Problem statement: Microstructure of the grain will influence the properties of a polycrystalline manganites when different dopant is introduced. In this work, an effort had been made to investigate the influence of Ca, Ba and Sr substitution in La site. Approach: Polycrystalline manganites compound of La0.67A0.33MnO3 where A = Ba, Sr and Ca had been prepared via conventional solid-state reaction … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Photooxidation Pathways of Dicarboxylic Acids in Atmospheric DropletsL.M. Yang, L.E. Yu, M.B. RayLow molecular weight (LMW) dicarboxylic acids (DCAs) have received increasing attention because of their hygroscopic properties and capability of acting as cloud condensation nuclei (CCN). Based on the concentration profiles of intermediates identified during laboratory photooxidation of C7-C9 DCAs in a liquid-phase reaction system, chemometric analyses were conducted to examine the degradation pathways of DCAs for the formation of secondary … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Boron Carbonitride (BCN) Thin Films Deposited by Radiofrequency and Microwave Plasma Enhanced Chemical Vapor DepositionM.A. Mannan, M. Nagano, K. Shigezumi et al.Boron carbonitride (BCN) thin films with a thickness of ~4 µm were synthesized on Si (100) substrate by radiofrequency and microwave plasma enhanced chemical vapor deposition using trimethylamine borane [(CH3)3N.BH3)] as a molecular precursor. The microstructures of the films were evaluated using field emission scanning electron microscopy (FE-SEM) and X-ray diffractometry (XRD). Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractNanoceramic Matrices: Biomedical ApplicationsWilli Paul, Chandra P. SharmaNatural bone consisted of calcium phosphate with nanometer-sized needle-like crystals of approximately 5-20 nm width by 60 nm length. Synthetic calcium phosphates and Bioglass are biocompatible and bioactive as they bond to bone and enhance bone tissue formation. This property is attributed to their similarity with the mineral phase of natural bone except its constituent particle size. Calcium phosphate ceramics … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,361 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPhase Transition in Φ6 PotentialHatem WidyanScalar field theory with an asymmetric potential was studied at zero temperature and high-temperature for Φ6 potential. The equations of motion are solved numerically to obtain O(4) spherical symmetric and O(3) cylindrical symmetric bounce solutions. These solutions control the rates for tunneling from the false vacuum to the true vacuum by bubble formation. The range of validity of the thin-wall … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 6,878 accessesView PDFCite
