This study provide better understanding of the influence of calcination temperatures on the magnetic properties of Nickel Zinc ferrite consequently enable to tailor the magnetic properties of Nickel Zinc ferrite for specific application. Magnetic nanoparticles of Nickel Zinc ferritewere synthesized by … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 21 Mar 2014 · 6,883 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Novel Enhancement Technique of the Hill Cipher for Effective Cryptographic PurposesA. F.A. Abidin, O. Y. Chuan, M. R.K. AriffinProblem statement: The Hill cipher is the first polygraph cipher which has a few advantages in data encryption. However, it is vulnerable to known plaintext attack. Besides, an invertible key matrix is needed for decryption. It may become problematic since an invertible key matrix does not always exist. Approach: In this study, a robust Hill algorithm (Hill++) has been proposed. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 8,547 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Role of Sine and Cosine Components in Love Waves and Rayleigh Waves for Energy Hauling during EarthquakeZainal Abdul Aziz, Dennis Ling Chuan ChingProblem statement: Love waves or shear waves are referred to dispersive SH waves. The diffusive parameters are found to produce complex amplitude and diffusive waves for energy hauling. Approach: Analytical solutions are found for analysis and discussions. Results: When the standing waves are compared with the Love waves, similar cosine component is found in both waves. Energy hauling between waves … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,586 accessesView PDFCite
Research ArticleOpen accessIn the author namesCharacterization of Pullulanase Type II from Bacillus cereus H1.5Hii Siew Ling, Tau Chuan Ling, Rosfarizan Mohamad, Arbakariya B. AriffProblem statement: Pullulanase is one of the important enzymes in starch industry. Search for the pullulanase with distinct features, possibly from easily grown bacterium, is of interest for industrial applications Approach: The extracellular pullulanase produced by Bacillus cereus HI.5 was purified by chromatographic method of DEAE-Sepharose, followed by Superdex gel filtration. The enzyme was characterized in terms of the optimal … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 8,813 accessesView PDFCite
Research ArticleOpen accessIn the author namesClassification of Pressure Range Based on the Characterization of Escherichia coli Cell Disruption in High Pressure HomogenizerRamakrishnan Nagasundara Ramanan, Beng Ti Tey, Tau Chuan Ling, Arbakariya B. AriffProblem statement: High pressure Homogenizer was used for cell disruption in many studies. But no work was carried out to study the characteristics of cell disruption in a wide range of pressure. Approach: The characteristics of Escherichia coli cell disruption was studied in Avestin small scale homogenizer by varying the operating pressure (50-1500 bar), cell concentration in the feed (1.39-12.51 … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 9,632 accessesView PDFCite
Research ArticleOpen accessIn the author namesOptimal Control of the D-Policy M/G/1 Queueing System with Server BreakdownsKuo-Hsiung Wang, Ching-Chang Kuo, Jau-Chuan KeThis study deals with a single server in the D-policy M/G/1 queueing system in which the server is turned off at the end of each complete period and is activated again only when the cumulative completion times of the customers in the system exceeds a given level D. While the server is working, he is subject to breakdowns according to … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,606 accessesView PDFCite
Research ArticleOpen accessIn the author namesC-Terminal Region of Dengue Virus Nonstructural Protein 1 Is Involved in Endothelial Cell Cross-Reactivity via Molecular MimicryShu-Wen Wan, Chiou-Feng Lin, Mei-Chun Chen et al.Infection with dengue virus (DV) causes diseases ranging from self-limited dengue fever to life-threatening dengue hemorrhagic fever and dengue shock syndrome. Vascular leakage, thrombocytopenia and bleeding are the clinical manifestations associated with dengue hemorrhage. We previously showed that anti-DV nonstructural protein 1 (NS1) antibodies (Abs) cross-reacted with endothelial cells. The potential target proteins on endothelial cell surface recognized by anti-DV … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,564 accessesView PDFCite
Research ArticleOpen accessIn the author namesPatient and Mouse Antibodies against Dengue Virus Nonstructural Protein 1 Cross-React with Platelets and Cause Their Dysfunction or DepletionChiou-Feng Lin, Huan-Yao Lei, Ching-Chuan Liu et al.Thrombocytopenia is a clinical manifestation in dengue virus (DV) infection, yet its pathogenic mechanisms are unresolved. We previously showed that dengue patient sera contained antibodies cross-reactive with platelets. In this study, we demonstrated that the anti-platelet activity of dengue patient sera was due to the antibodies against DV nonstructural protein 1 (NS1). Studies using DV-infected or recombinant NS1-immunized mouse sera … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,327 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnti-Prm Antibody as an Autoantibody in Dengue Virus InfectionKao-Jean Huang, Yu-Tien Cheng, Yee-Shin Lin et al.We have reported that anti-prM antibody is an enhancing antibody that enhances DV infection of non-Fc receptor bearing cells by dual specificity. We identified the epitope recognized by this anti-prM antibody, M3, which is located at the a.a.53-67of the prM protein nearby the prM/M cleavage junction and these anti-M3 antibodies could be detected in dengue patients sera. Surprisingly, this anti-prM … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,308 accessesView PDFCite
Research ArticleOpen accessIn the author namesGeneration of Anti-platelet Autoantibody During Dengue Virus InfectionKao-Jean Huang, Yee-Shin Lin, Hsiao-Sheng Liu et al.Dengue virus infection causes dengue fever, Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS). Thrombocytopenia is common in dengue fever and is always found in DHF/DSS. The pathogenesis of thrombocytopenia is poorly understood. To further understand the relationship between anti-dengue virus antibody and anti-platelet antibody, we generated monoclonal anti-dengue virus antibodies from the dengue virus infected mice that developed … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,537 accessesView PDFCite
